Subject: [PATCH 001/878] Optimize logical optimizer: skip map_subqueries +
 in-place rewriting (#22298)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Supersedes #20837. That PR's branch was rebased onto current `main`;
GitHub does
not allow reopening a closed PR once its branch has been force-pushed,
so this is
a fresh PR carrying the same work, rebased and re-benchmarked.

## Rationale for this change

`Optimizer::optimize` runs every logical optimizer rule over the whole
plan,
repeatedly, until a fixed point. Benchmarking the optimizer in isolation
(SQL
parsing and analysis excluded) surfaced two avoidable costs:

1. `rewrite_with_subqueries` calls `map_subqueries` at every plan node,
walking
every expression tree via ownership-based `transform_down` — even for
plans
   with no subquery expressions at all, which is the common case.
2. The ownership-based `TreeNode::rewrite` traversal performs an
`Arc::unwrap_or_clone` + `Arc::new` cycle at every child node,
re-allocating
   the `Arc` spine on every pass even when nothing changes.

## What changes are included in this PR?

Three optimizations:

1. **`map_subqueries` short-circuit** — skip the expression-tree walk
when a node
   has no subquery expressions.
2. **`plan_has_subqueries` per-pass check** — when the whole plan has no
subqueries, bypass `rewrite_with_subqueries` entirely and use the
cheaper
   in-place traversal.
3. **`rewrite_plan_in_place` with `Arc::make_mut`** — a private
`map_children_mut` helper in the optimizer crate mutates
`Arc<LogicalPlan>`
children in place (copy-on-write; free when the refcount is 1, the
common
case in the optimizer), avoiding the `Arc::unwrap_or_clone` + `Arc::new`
cycle. The owned-plan rule API is bridged with `std::mem::take`, which
is
allocation-free because `LogicalPlan::default()` is an `EmptyRelation`
that
   shares the process-wide static empty schema.

Also adds optimizer-only benchmarks to `sql_planner.rs` that isolate
optimizer
cost from SQL parsing/analysis.

### Benchmark results (optimizer-only, criterion, this PR vs `main`)

| Benchmark | main | this PR | Change |
|---|---|---|---|
| optimizer_select_one_from_700 | 200 µs | 202 µs | +1% (noise) |
| optimizer_select_all_from_1000 | 4.71 ms | 4.13 ms | **−12%** |
| optimizer_join_chain_4 | 136 µs | 103 µs | **−24%** |
| optimizer_join_chain_8 | 445 µs | 363 µs | **−18%** |
| optimizer_wide_filter_200 | 4.91 ms | 3.47 ms | **−29%** |
| optimizer_wide_aggregate_100 | 2.10 ms | 1.50 ms | **−29%** |
| optimizer_correlated_exists | 187 µs | 185 µs | −1% (noise) |
| optimizer_join_4_with_agg_filter | 384 µs | 276 µs | **−28%** |
| optimizer_tpch_all | 12.25 ms | 9.14 ms | **−25%** |
| optimizer_tpcds_all | 220 ms | 170 ms | **−23%** |

Measured A/B on a single machine: for the baseline run the two optimizer
rule
files were reverted to `main` (keeping the new benchmark code), then
restored, so
only the optimization itself is being measured. The
`optimizer_tpcds_all` number
was confirmed across multiple back-to-back runs after an initial reading
was
distorted by machine interference.

### Possible future work (not in this PR)

The `mem::take` bridge in `rewrite_plan_in_place` is allocation-free,
but it still
extracts an owned plan for every `(node, rule)` pair up front — before
the rule
decides whether it will transform — and the overwhelming majority of
those pairs
are no-ops. A dynamic "lazy handle" rule API (the rule receives a handle
that
derefs to `&LogicalPlan` for free and only pays the copy-on-write / move
when it
calls `make_mut` / `replace`) would let the framework skip the
extraction for
no-op rule invocations entirely. That is a breaking change to the public
`OptimizerRule` trait and is out of scope here; it is being prototyped
separately.

## Are these changes tested?

Yes. The existing optimizer test suite (713 tests across
`datafusion-optimizer`)
passes unchanged. The optimizations are behavior-preserving: the
in-place
traversal produces the same plans as the ownership-based traversal, and
the
subquery short-circuit only skips work that is provably a no-op.

## Are there any user-facing changes?

No. No new public API — the in-place traversal helper is private to the
optimizer crate. Optimization is faster; output plans are unchanged.

Subject: [PATCH 004/878] fix: preserve null_aware on logical JoinNode proto
 round-trip (#22104)

## Summary

Closes #22065.

`null_aware` was missing from `JoinNode` in the logical proto
(it was added to the physical `HashJoinExecNode` in #19635). The
encoder dropped it via `..` destructuring and the decoder had no
field to restore it from, so any `to_proto` -> `from_proto` round
trip silently downgraded a null-aware LeftAnti (NOT IN semantics)
to a plain LeftAnti and returned wrong rows.

## Changes

- Add `bool null_aware = 9;` to `JoinNode`.
- Decoder switches to `Join::try_new`, plumbing `null_aware` and
  `null_equality` (same bug, same path) from the wire.
- Encoder destructure binds `schema: _` instead of `..`, so any
  future `Join` field is a compile error here instead of a silent
  drop.
- Decoder rejects mismatched `left_join_key`/`right_join_key`
  lengths via `proto_error`.
- Regression tests `roundtrip_join_null_aware` and
  `roundtrip_join_null_equality`, each exercising one non-default
  field.

## Test plan

- `cargo test -p datafusion-proto --test proto_integration
cases::roundtrip_logical_plan` passes.
- Clippy clean.

Subject: [PATCH 005/878] perf: collapse chained projections in a single
 optimizer pass; reduce memory usage / recursion (#22389)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22391.

## Rationale for this change

Long chains of consecutive projections (e.g. `SELECT *, <expr> AS dN
FROM ...` stacked N times, with depth-K nested CASE per step) caused
planning to use multi-GB of RAM and tens of seconds of wall time,
scaling superlinearly in chain length and CASE depth. See #22391 for the
OOM/timing data.

## What changes are included in this PR?

Three independent fixes targeting the same workload:

1. **Physical chain collapse**
(`datafusion/physical-plan/src/projection.rs`): replace the pairwise
recursive unification in `ProjectionExec::try_swapping_with_projection`
with `try_collapse_projection_chain`, which walks the entire run of
consecutive `ProjectionExec`s and builds **one** final `ProjectionExec`
(saves N-1 intermediate constructions and their `compute_properties`
calls). Leaf pushdown into a non-`Projection` input is preserved by
calling `remove_unnecessary_projections` once at the end.

2. **Logical iterative merge**
(`datafusion/optimizer/src/optimize_projections/mod.rs`): wrap
`merge_consecutive_projections` in an internal loop so an N-deep
`LogicalPlan::Projection` chain collapses in a single rule application
instead of N outer fixpoint passes.

3. **`update_expr` Column-equality short-circuit**
(`datafusion/physical-expr/src/projection.rs`): when substituting a
Column with one that equals it (the pass-through case during chain
collapse), return `Transformed::no` so `transform_up` does not rebuild
the enclosing `CaseExpr` / `CaseBody`. This is the OOM fix — it
eliminates the O(N² · K²) cascade of CASE allocations.

## Are these changes tested?

- yes, existing test + added bench

  | Stage | Time | Δ vs master |
  |---|---:|---:|
  | master | 623 ms | — |
  | + chain collapse + logical merge loop | 364 ms | −41.5% |
| + `update_expr` Column-equality short-circuit | **155 ms** |
**−75.4%** |

  (criterion p<0.05, CI [−75.67%, −75.16%])

## Are there any user-facing changes?

No public API change.

Subject: [PATCH 006/878] PushdownFilter optimizations  (#21668)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Addresses #20002
- Includes #21643
- Looks like we had a similar idea with #21667, cc @kumarUjjawal
  - [x] I like the name `try_unchecked` more so I would adopt that
- I'm not sure if we need to keep the unaliasing, the optimizer rule
already does that
- I have additional changes for more aggressive optimizations, so I'm
happy to combine the PRs or rebase after merge

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

 - Add a hidden `Filter::new` constructor that skips type-checking
 - Less allocations, more modification of mutable plan nodes
 - Less cloning, use references when possible

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Relying on existing tests mostly, added a few more tests.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

`make_filter` is deprecated, probably wasn't meant to be a public
function.

Subject: [PATCH 007/878] refactor(parquet-datasource): extract
 DecoderProjection from build_stream (#22398)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #.

## Rationale for this change

`RowGroupsPrunedParquetOpen::build_stream` inlines the
`build_projection_read_plan` + `reassign_expr_columns` +
`make_projector` + `replace_schema` quartet right next to the decoder /
stream wiring, which makes the opener's main orchestration body harder
to follow and mixes two concerns: building the per-file projection vs.
wiring it through the push-decoder stream.

This PR isolates that block behind a small `DecoderProjection` type
whose public surface is just \"give me the projection mask\" and
\"project this decoded batch onto the output schema.\"

## What changes are included in this PR?

* New `decoder_projection` module with a `DecoderProjection` type:
* `DecoderProjection::try_new(projection, physical_file_schema,
parquet_schema, output_schema)` constructs the per-file projection in
one call.
  * `projection_mask()` returns the mask installed on every decoder run.
* `map(&batch)` applies the projector and, when needed, rebuilds the
batch with `output_schema` to recover metadata / nullability that the
file schema does not carry.
  * Fields are private.
* `PushDecoderStreamState` collapses three fields (`projector`,
`output_schema`, `replace_schema`) into a single `decoder_projection:
DecoderProjection`. `project_batch` becomes a one-line delegate to
`DecoderProjection::map`.
* `replace_schema` is now derived from the projector's *output* schema
(rather than the read plan's projected schema) so it stays correct under
future widening of the decoder mask.
* `DecoderBuilderConfig` carries the projection mask directly
(`projection_mask: &ProjectionMask`) instead of the full
`ParquetReadPlan`, since the read plan's `projected_schema` is no longer
needed in this layer.

No behaviour change.

## Are these changes tested?

Covered by existing tests:

* \`cargo test -p datafusion-datasource-parquet\` — 123 pass.
* \`cargo test -p datafusion --test parquet_integration\` — 202 pass.
* \`cargo clippy -p datafusion-datasource-parquet --all-targets
--all-features -- -D warnings\` — clean.

## Are there any user-facing changes?

No. All affected types are \`pub(crate)\`.

Subject: [PATCH 008/878] proto: add proto converter reference to
 PhysicalExtensionCodec trait (#21055)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #21056

## Rationale for this change

Custom `ExecutionPlan` nodes that store `PhysicalExpr` fields cannot
participate in expression deduplication during serialization because
`PhysicalExtensionCodec::try_encode`/`try_decode` lack access to the
`PhysicalProtoConverterExtension`.

## What changes are included in this PR?

- Added `proto_converter: &dyn PhysicalProtoConverterExtension`
parameter
  to `PhysicalExtensionCodec::try_decode` and `try_encode`
- Updated all implementations: `DefaultPhysicalExtensionCodec`,
`ComposedPhysicalExtensionCodec`, `ForeignPhysicalExtensionCodec` (FFI),
  and all examples
- Updated call sites in `PhysicalPlanNode` serialization/deserialization
- FFI bridge passes `DefaultPhysicalProtoConverter` as a fallback

## Are these changes tested?

Yes — added `test_custom_node_with_dynamic_filter_dedup_roundtrip` which
verifies that a `DynamicFilterPhysicalExpr` shared between a
`FilterExec`
and a custom `ExecutionPlan` node preserves its shared inner state after
a
roundtrip through `DeduplicatingProtoConverter`.

## Are there any user-facing changes?

Breaking API change: `PhysicalExtensionCodec::try_decode` and
`try_encode`
now take an additional `&dyn PhysicalProtoConverterExtension` parameter.
All custom codec implementations must be updated.

Subject: [PATCH 009/878] Revert "Add `ExecutionPlan::apply_expressions()`
 (#20337)" (#22437)

## Which issue does this PR close?

- Reverts #20337
- Addresses concerns raised in
https://github.com/apache/datafusion/pull/22415
- Closes https://github.com/apache/datafusion/pull/22415

## Rationale for this change

`ExecutionPlan::apply_expressions()` was added in #20337 with no default
implementation, forcing every custom `ExecutionPlan`, `FileSource`, and
`DataSource` implementor to add the method as part of upgrading to
DataFusion 54.

As discussed on #22415, per @LiaCastaneda and @adriangb the method is
not yet called from anywhere in DataFusion and the originally intended
use (dynamic-filter discovery/serialization for distributed scenarios)
is blocked on other in-progress work (#20009, #21350).

The combined effect on downstream users is a required code change with
no immediate benefit, and ambiguity about what a "correct"
implementation even means today (e.g. is returning
`Ok(TreeNodeRecursion::Continue)` is safe right now but becomes
incorrect as soon as the method starts being used by an optimizer pass?.

The plan agreed in the discussion is to remove the API from the 54.0
release and re-add it together with the concrete consumer that needs it.
cc @adriangb @LiaCastaneda @milenkovicm.

## What changes are included in this PR?

`git revert -m 1` of the merge commit, with the following manual
conflict resolutions and follow-ups:

## Are these changes tested?

By CI

## Are there any user-facing changes?

Yes -- this removes the new public API:

- `ExecutionPlan::apply_expressions`
- `FileSource::apply_expressions`
- `DataSource::apply_expressions`

These were only added in 54 and are not yet released. Custom
implementors no longer need to implement these methods.

Subject: [PATCH 010/878] Fix: Infer placeholder type from subquery (#22436)

## Which issue does this PR close?

Closes #15979.

## Rationale for this change

`$1 IN (SELECT ...)` left the placeholder untyped because
`infer_placeholder_types` had no arm for `InSubquery` and made
`get_parameter_types()` return `None` for these placeholders.

## What changes are included in this PR?

Adds the `InSubquery` arm to `infer_placeholder_types`, reading the type
from the subquery's projected column. Covers both `IN` and `NOT IN`.

## How are these changes tested?

Unit tests for `IN` and `NOT IN` placeholder inference, plus end-to-end
sqllogictests with `PREPARE`/`EXECUTE`.

## Are there any user-facing changes?

No.

## Which issue does this PR close?

- Closes #21928.

## Rationale for this change

ScalarValue::compact copies array data for container types to release
sliced-buffer overhead, but never called .gc() on nested StringViewArray
/ BinaryViewArray. A scalar extracted from a large batch would therefore
still hold a reference to the entire original view backing buffer,
negating the benefit of compaction for any list, struct, or map whose
values are view-typed.
## What changes are included in this PR?

- ScalarValue::compact now compacts nested view buffers for all
container types (List, LargeList, FixedSizeList, ListView,
LargeListView, Struct, Map), trimming StringViewArray / BinaryViewArray
backing buffers to only the
  referenced bytes.
- The internal compact_view_buffers helper recursively handles
FixedSizeList, ListView, LargeListView, and Map.

## Are these changes tested?

new unit tests are added in scalar::tests, one per container type. Each
test verifies that after compact() the backing buffer is reduced to
exactly the bytes of the referenced string, and that the scalar value is
preserved.

## Are there any user-facing changes?

No. The public compact / compacted API is unchanged; this PR only fixes
the behaviour for view-typed nested arrays.

Subject: [PATCH 012/878] Split proto serialization to encapsulate private
 state (#21835) (#21929)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #21835.

## Rationale for this change

`datafusion-proto` serializes every built-in `PhysicalExpr` through a
single
~300-line `downcast_ref` chain, with a mirror `match` on the decode
side. That
chain lives outside the crate where each expression is defined, so every
field
an expression wants to round-trip has to be made `pub`. #21807 is the
cautionary tale: it had to add five `pub` "proto-only, not stable" items
to
`DynamicFilterPhysicalExpr` just to serialize an `RwLock`-wrapped inner.

This PR adds the infrastructure so a `PhysicalExpr` can serialize itself
and
keep its state private.

## What changes are included in this PR?

A `PhysicalExpr` can now opt into serializing itself, in both
directions:

```rust
fn try_to_proto(&self, ctx: &PhysicalExprEncodeCtx) -> Result<Option<PhysicalExprNode>>
fn try_from_proto(node: &PhysicalExprNode, ctx: &PhysicalExprDecodeCtx) -> Result<Arc<dyn PhysicalExpr>>
```

`try_to_proto` returning `Ok(None)` (the default) means "fall through to
the
old downcast chain", so the change is purely additive — nothing is
forced to
migrate.

`Column` and `BinaryExpr` are migrated as working demos; everything
else stays on the old path and migrates later, one expression at a time,
with
no wire-format change.

Five stacked commits, each builds green on its own and is independently
reviewable (or splittable into its own PR):

1. **Extract `datafusion-proto-models` crate** — move the `.proto` file
and
   prost-generated types into a lightweight crate (mirrors the existing
   `datafusion-proto-common` split).
2. **Add the `try_to_proto` hook** — feature-gated, off by default.
3. **Migrate `Column` encode.**
4. **Add the decode side and migrate `Column` decode.**
5. **Migrate `BinaryExpr`** (both directions).

## A few design decisions worth flagging

- **`FromProto` / `TryFromProto` traits instead of plain `From` /
`TryFrom`.**
  Once the prost types move into their own crate they are *foreign* to
`datafusion-proto`, and the orphan rule forbids `impl From<&protobuf::X>
for Y`
when both `X` and `Y` are foreign. So those conversions become
`FromProto` /
`TryFromProto` traits in `datafusion_proto::convert`, and callers go
from
`(&x).into()` to `Y::from_proto(&x)`. This is a known workaround, not
the end
  state — see Future work.
- **The ctx is a concrete struct, not `&dyn`.** `PhysicalExprEncodeCtx`
/
`PhysicalExprDecodeCtx` wrap a sealed dispatch trait. Keeping them
concrete
keeps `&dyn` out of every expression's signature and gives a stable
place to
add helpers (UDF encoding, registry hooks) later without churning a
public
  trait.
- **`try_from_proto` takes the whole `PhysicalExprNode`**, not the
pre-unwrapped variant payload, so every expression's decoder has the
same
  signature and can still see outer-node fields like `expr_id`.

## Are these changes tested?

No new behavior, so no new tests. `Column` and `BinaryExpr` produce and
consume
the same wire format as before; the existing `roundtrip_physical_plan` /
`roundtrip_physical_expr` tests already cover both directions and now
exercise
the new path.

## Are there any user-facing changes?

Small API breaks in `datafusion-proto`:

- `try_from_physical_plan_with_converter` /
`try_into_physical_plan_with_converter`
  move to a `PhysicalPlanNodeExt` trait — callers add
  `use datafusion_proto::physical_plan::PhysicalPlanNodeExt;`.
- Foreign-foreign `From` / `TryFrom` conversions become `FromProto` /
  `TryFromProto` (see Design decisions above).
- `datafusion_proto::generated::*` is deprecated in favor of
  `datafusion_proto::protobuf`; it still works.

The new `proto` feature on `datafusion-physical-expr(-common)` is off by
default, so crates that don't serialize plans pay nothing.

## Future work

- Migrate the remaining built-in expressions — including
`DynamicFilterPhysicalExpr`, the original motivation — one per follow-up
PR.
- Apply the same pattern to `ExecutionPlan` serialization.
- Drop the `FromProto` / `TryFromProto` workaround: collapse
  `datafusion-proto-common` into `datafusion-proto-models` and push the
conversion impls down to the target-type crates so callers use plain
`From` /
`TryFrom` again. Full dep-graph analysis and a step-by-step plan are in

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+# Apache DataFusion Protobuf Models
+
+[Apache DataFusion] is an extensible query execution framework, written in Rust, that uses [Apache Arrow] as its in-memory format.
+
+This crate contains the [prost]-generated Rust types for DataFusion's logical
+and physical plan protobuf schemas. It is intentionally kept narrow: it has no
+DataFusion dependencies beyond [`datafusion-proto-common`] and exposes only the
+generated structs (and optional [pbjson]/[serde] support).
+
+This crate is consumed by [`datafusion-proto`] and may also be depended on
+directly by other DataFusion crates that need to refer to the proto schema
+types without pulling in the full [`datafusion-proto`] surface.
+
+Most projects should use the [`datafusion-proto`] crate directly, which
+re-exports this module. If you are already using the [`datafusion-proto`]
+crate, there is no reason to use this crate directly in your project as well.

Subject: [PATCH 013/878] fix: indentation for markdown block comments in
 docstrings (#22409)

## Which issue does this PR close?

Minor enough that I didn't open an issue for it.

## Rationale for this change
There must be some issue in vim's syntax highlighting, possibly in
https://github.com/rust-lang/rust.vim, but these minor inconsistencies
break the sytax highlighting.


## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.

## Are these changes tested?

Subject: [PATCH 015/878] chore: Cleanup and refactor `build_join` in
 `ScalarSubqueryToJoin` (#22316)

## Which issue does this PR close?

- N/A

## Rationale for this change

This PR cleans up and refactors `build_join`, which is used as part of
rewriting correlated subqueries.

## What changes are included in this PR?

* This routine only needs to handle correlated subqueries now, so
simplify the code and add an assert to that effect
* Clarify variable names
* Improve comments
* Hoist a few variables outside of loops, when possible
* Use `when`, `lit` and `not` helpers to build the `CASE` expression

## Are these changes tested?

Yes, covered by existing tests.

## Are there any user-facing changes?

No, no functional changes at all.

Subject: [PATCH 016/878] fix(unparser): fold Limit/Sort into outer SELECT when
 Projection claims Aggregate through them (#21375)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #21374

## Rationale for this change

When the SQL unparser encounters a Projection → Limit → Aggregate or
Projection → Sort → Aggregate plan shape where aggregate aliases are
inlined (no intermediate Projection between
Limit/Sort and Aggregate), it emits the aggregate expressions twice -
once in the outer SELECT and once inside a spurious derived subquery.
The outer SELECT also references columns that are
  out of scope.

This plan shape doesn't occur from the SQL parser (which inserts an
intermediate Projection), but optimizers and plan builders can produce
it.

## What changes are included in this PR?

datafusion/sql/src/unparser/plan.rs:

- reconstruct_select_statement now returns Result<bool> - true when it
found and claimed an Aggregate node for the current SELECT.
- In the Projection arm of select_to_sql_recursively, after claiming an
Aggregate, if the Projection's direct child is a Limit or Sort, fold its
clauses (LIMIT/OFFSET or ORDER BY/LIMIT) into
the current query and recurse into the child's input, skipping the
Limit/Sort node. This prevents the Limit/Sort arm from seeing
already_projected and wrapping everything in a spurious
  derived subquery.

  datafusion/sql/tests/cases/plan_to_sql.rs:

- roundtrip_aggregate_over_subquery — roundtrip test for the
parser-generated plan shape (Projection between Limit and Aggregate),
confirming it still works.
- roundtrip_subquery_aggregate_with_column_alias - roundtrip test for
SELECT id FROM (SELECT max(j1_id) FROM j1) AS c(id).
- test_unparse_aggregate_over_subquery_no_inner_proj - manually
constructed Projection → Limit → Aggregate plan, verifying the Limit is
folded into the outer SELECT.
- test_unparse_aggregate_no_outer_rename - manually constructed
Projection → Aggregate with no outer rename, verifying aggregate aliases
are preserved.
- test_unparse_aggregate_with_sort_no_inner_proj - manually constructed
Projection → Sort → Aggregate plan, verifying the Sort is folded into
the outer SELECT.

## Are these changes tested?

Yes. Five new tests covering:
  1. Parser-generated roundtrip (regression guard)
  2. Column alias roundtrip with subquery aggregate
  3. Limit folding with manually constructed plan (was the primary bug)
  4. Aggregate alias preservation without outer rename
  5. Sort folding with manually constructed plan (same bug pattern)


## Are there any user-facing changes?

No API changes. The fix corrects SQL output for programmatically
constructed logical plans that have Projection → Limit → Aggregate or
Projection → Sort → Aggregate shapes without an intermediate Projection.

Subject: [PATCH 017/878] fix(substrait): dedupe names of aggregate measures,
 not just groupings (#22453)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

When the substrait consumer hits an `Aggregate` with two identical
measures (e.g. `sum(a)` present twice), planning fails with `Schema
contains duplicate unqualified field name`. Substrait carries column
names at the plan root rather than on the measures themselves, so the
measures arrive at `Aggregate` schema construction without aliases --
and two identical exprs produce two identical field names. PR #20539
fixed the `NameTracker` to dedupe duplicate names in the consumer, but
it was only applied to grouping expressions, not to the measures.

The planner sees:

```
field 1: (qualifier: None, name: "sum(data.a)")
field 2: (qualifier: None, name: "sum(data.a)")
```

which is rejected when constructing the Aggregate's output schema.


## What changes are included in this PR?

Run aggregate measures through the same `NameTracker` like the grouping
expressions in `from_aggregate_rel`

## Are these changes tested?

Yes -- added a roundtrip test `aggregate_identical_measures`. Without
the fix it produces `Error: SchemaError(DuplicateUnqualifiedField {
name: "sum(data.a)" }, Some(""))`

## Are there any user-facing changes?

No.

Subject: [PATCH 018/878] fix ^ evaluates as bitwise XOR instead of
 exponentiation (#22314)

## Which issue does this PR close?

- Closes #22252.

## Rationale for this change

In PostgreSQL, the `^` operator represents exponentiation, but
DataFusion was interpreting it as bitwise XOR. This caused
PostgreSQL-dialect queries such as `SELECT 2 ^ 3;` to return `1` instead
of `8`.

This change aligns DataFusion's PostgreSQL SQL semantics with PostgreSQL
for this operator while preserving existing non-PostgreSQL behavior.

## What changes are included in this PR?

- Added PostgreSQL-specific handling for `BinaryOperator::PGExp` during
SQL expression lowering.
- Lowered PostgreSQL `^` expressions to the built-in `power(left,
right)` scalar function instead of treating them as bitwise XOR.
- Kept existing generic-dialect `^` behavior unchanged.
- Kept PostgreSQL bitwise XOR behavior unchanged via `#`.
- Added a sqllogictest regression covering `SELECT 2 ^ 3;` under the
PostgreSQL parser dialect.

## Are these changes tested?

Yes.

Added a regression test in scalar.slt to verify that PostgreSQL-dialect
`^` is evaluated as exponentiation.

Validated with:

```bash
cargo test -p datafusion-sqllogictest --test sqllogictests scalar
```

## Are there any user-facing changes?

Yes.

For the PostgreSQL SQL parser dialect, `^` now behaves as exponentiation
instead of bitwise XOR, matching PostgreSQL semantics. Generic-dialect
behavior is unchanged, and PostgreSQL bitwise XOR remains available
through `#`.

## Which issue does this PR close?

- Closes #22363.

## Rationale for this change

The partitioned_by_file_group field was introduced in #21351 and #21342
but not added to the protobuf schema, breaking `datafusion-distributed`.

## What changes are included in this PR?

- Add optional `bool partitioned_by_file_group = 14` to
`FileScanExecConf` in `datafusion.proto`
- Serialize the field in `to_proto.rs`
- Deserialize the field in `from_proto.rs`
- Regenerate prost/pbjson code

## Are these changes tested?

Yes, added roundtrip_parquet_exec_partitioned_by_file_group test.

## Are there any user-facing changes?

No

Subject: [PATCH 020/878] perf: Optimize `translate` to use new bulk-NULL
 string builders (#22171)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22170.

## Rationale for this change

This PR refactors and optimizes the `translate` UDF. In particular, we
switch to using the new bulk-NULL string builders, avoiding per-row NULL
computation, and avoid an intermediate string copy by using
`append_with` / `append_byte_map`.

Benchmarks (Arm64):

Scalar (scalar_from_to)

  - size=1024, str_len=8: 13.6 µs → 8.5 µs (-37.5%)
  - size=1024, str_len=32: 26.2 µs → 20.6 µs (-21.4%)
  - size=1024, str_len=128: 87.9 µs → 68.9 µs (-21.6%)
  - size=1024, str_len=1024: 572.9 µs → 531.1 µs (-7.3%)
  - size=4096, str_len=8: 51.6 µs → 31.4 µs (-39.1%)
  - size=4096, str_len=32: 103.1 µs → 79.8 µs (-22.6%)
  - size=4096, str_len=128: 341.1 µs → 273.4 µs (-19.8%)
  - size=4096, str_len=1024: 2.3 ms → 2.1 ms (-8.7%)

Array — ASCII (array_from_to)

  - size=1024, str_len=8: 50.6 µs → 21.2 µs (-58.1%)
  - size=1024, str_len=32: 106.5 µs → 26.7 µs (-74.9%)
  - size=1024, str_len=128: 265.4 µs → 59.9 µs (-77.4%)
  - size=1024, str_len=1024: 1760.8 µs → 797.1 µs (-54.7%)
  - size=4096, str_len=8: 211.4 µs → 84.3 µs (-60.1%)
  - size=4096, str_len=32: 435.2 µs → 120.6 µs (-72.3%)
  - size=4096, str_len=128: 1079.0 µs → 487.6 µs (-54.8%)
  - size=4096, str_len=1024: 7.2 ms → 3.2 ms (-55.6%)

Array — non-ASCII (array_from_to_non_ascii)

  - size=1024, str_len=8: 71.2 µs → 68.6 µs (-3.7%)
  - size=1024, str_len=32: 228.8 µs → 236.9 µs (+3.5%)
  - size=1024, str_len=128: 880.5 µs → 881.4 µs (+0.1%)
  - size=1024, str_len=1024: 6.7 ms → 6.7 ms (+0.6%)
  - size=4096, str_len=8: 375.5 µs → 376.6 µs (+0.3%)
  - size=4096, str_len=32: 1041.2 µs → 1079.6 µs (+3.7%)
  - size=4096, str_len=128: 3.5 ms → 3.6 ms (+2.9%)
  - size=4096, str_len=1024: 27.0 ms → 26.8 ms (-0.7%)

## What changes are included in this PR?

* Switch from using the Rust StringBuilders to our new bulk-NULL string
builders
* Switch from per-row NULL checks to computing the NULL bitmaps with
`NullBuffer::union_many`
* Use `append_with` and `append_byte_map` rather than `append_value`,
which avoids an intermediate scratch buffer
* Refactor lookup table code to use a single `TranslationTable` enum
* Add a benchmark for the "varying `from`/`to`, Unicode strings" case
* Add a unit test

## Are these changes tested?

Yes; new test added.

## Are there any user-facing changes?

No.

Subject: [PATCH 021/878] perf: Optimize `overlay` with new string builder
 (#22182)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22181.

## Rationale for this change

This PR optimizes `overlay` by switching to the new bulk-NULL string
builders, and also taking advantage of `append_with` to avoid copying
into an intermediate `String`. Along the way, we also optimize character
counting for Unicode inputs, reducing the number of times we need to
walk the input string.

Benchmarks (Arm64):

StringArray

  - all_utf8: 3.6 ms → 1.85 ms (-48.6%)
  - ascii: 319.8 µs → 134.9 µs (-57.8%)
  - high_nulls: 400.7 µs → 75.1 µs (-81.3%)
  - low_nulls: 2.0 ms → 1.03 ms (-48.3%)
  - no_for: 2.1 ms → 1.12 ms (-46.8%)
  - no_nulls: 2.0 ms → 1.05 ms (-48.4%)

StringViewArray

  - all_utf8: 3.6 ms → 1.86 ms (-48.4%)
  - ascii: 313.8 µs → 133.8 µs (-57.4%)
  - low_nulls: 2.0 ms → 1.05 ms (-47.4%)
  - no_for: 2.1 ms → 1.12 ms (-46.7%)

## What changes are included in this PR?

* Switch to `BulkNullStringArrayBuilder` to build the result set, and
`NullBuffer::union_many` to compute NULLs in bulk
* Use `append_with` to avoid an intermediate string copy
* For Unicode inputs, replace three `char_indices` walks with a single
string traversal
* More comprehensive benchmark coverage
* Fix a misleading/inaccurate error message

## Are these changes tested?

Yes, covered by existing tests.

## Are there any user-facing changes?

No.

Subject: [PATCH 022/878] chore: Add existence (semi / anti ) benchmarks for
 hashjoinexec (#21821)

# Add Existence Join Benchmarks

  ### What changes are included in this PR?

  #### 1. End-to-end benchmarks (`benchmarks/src/hj.rs`)

Adds Q16-Q21 for RightSemi and RightAnti joins, following reviewer
feedback to focus on core axes:

  | Query | Join Type | Build Size | Probe Size | Hit Rate |
  |-------|-----------|------------|------------|----------|
  | Q16 | RightSemi | 25 (nation) | 1.5M (customer) | 100% |
  | Q17 | RightSemi | 100K (supplier) | 60M (lineitem) | 100% |
  | Q18 | RightSemi | 100K (supplier) | 60M (lineitem) | 10% |

+//! Criterion benchmarks for Hash Join with RightSemi/RightAnti joins with Int32 keys.
+//!
+//! ## Key Benchmark Axes
+//!
+//! - **Density**: How tightly distinct keys pack into their numeric range.
+//!   `density = num_distinct_keys / (max_key - min_key + 1)`.
+//!   Examples for 5 distinct keys:
+//!     - `[0, 1, 2, 3, 4]`      → 5/5  = 100% (fully packed)
+//!     - `[0, 2, 4, 6, 8]`      → 5/9  ≈  55% (every 2nd slot)
+//!     - `[0, 10, 20, 30, 40]`  → 5/41 ≈  12% (every 10th slot)
+//!
+//!   Why it matters for this workload: future potential semi/anti-join
+//!   fast paths could exploit densely packed build keys to outperform the
+//!   general hash-table path, which is largely insensitive to density.
+//!   Varying density across benchmarks helps surface those potential gains
+//!   under different key distributions. Density describes only the
+//!   build-side key layout; the per-probe match count is tracked
+//!   separately as fanout.
+//!
+//! - **Hit Rate**: The percentage of probe rows that find a match in the build side.
+//!   This controls how often the join produces output rows.
+//!
+//! Semi/anti joins can short-circuit after finding the first match, so these
+//! benchmarks help evaluate optimization strategies for existence checks.

Subject: [PATCH 024/878] chore: Disallow `reserve()` in clippy to prevent
 panics (#22386)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
In https://github.com/apache/datafusion/pull/22323, we have fixed panic
bugs by replacing `Vec::reserve()` with `Vec::try_reserve()`

This PR enforces a clippy rule to disallow `Vec::reserve()`
project-wise, to prevent future violations. Also it is easy to ignore
this lint with macro, if we can ensure the safety.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
They are not testable right now. To trigger the panic, we would need to
construct an Arrow array with more than `i32::MAX` elements, but Arrow
arrays are currently backed by flat vectors.

However, if Arrow supports an encoding such as RLE in the future, it may
become possible to represent such large arrays with constant memory. At
that point, these code paths would become vulnerable, so I think it is
better to fix them now.
## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 025/878] fix: `Operator::returns_null_on_null()` should
 include string concat (`||`) (#22458)

## Which issue does this PR close?

- Closes #22457

## Rationale for this change

`Operator::returns_null_on_null()` incorrectly claimed that the string
concatenation operator (`||`) treats NULL input as the empty string; it
does not. (Note that the `concat()` _function_ has the NULL->empty
string behavior, but the operator does not.)

While we're here, also teach `Operator::negate()` that
`Operator::RegexMatch` and `Operator::RegexNotMatch` are pairs, and the
same for the case-insensitive versions.

## What changes are included in this PR?

* Teach `Operator::returns_null_on_null()` that `||` returns NULL on
NULL inputs
* Teach `Operator::negate()` that `Operator::RegexMatch` and
`Operator::RegexNotMatch` are pairs; same for case-insensitive versions
* Fix typos in comments
* Add tests for new behavior

## Are these changes tested?

Yes; new tests added.

## Are there any user-facing changes?

Yes, but minor: expression simplification, outer join elimination, and
other optimizer can take advantage of this to optimize queries a bit
more effectively.

Subject: [PATCH 026/878] docs: add agent skill for datafusion-ffi crate
 patterns (#22327)

## Which issue does this PR close?

None.

## Rationale for this change

When writing FFI code, there are a variety of established patterns that
it is important to follow. This includes, but is not limited to, things
like ensuring we do not make FFI struct changes on patch releases and
ensuring we are following best practices for checking round trip trait
implementations. The goal of this PR is to add an agent skill to aid
both developers and code reviewers to find issues before they make it
into the code base.

## What changes are included in this PR?

- Add an agent skill.
- Update the AGENTS.md file to explain where to find this skill.

## Are these changes tested?

Yes, I have run the skill and it has already identified gaps in the
current implementation. Issues are opened for current gaps and linked
back to this PR for originating them.

## Are there any user-facing changes?

None

+name: datafusion-ffi
+description: Patterns and review checklist for the `datafusion-ffi` crate. Use whenever the user adds, edits, or reviews code under `datafusion/ffi/` — new `FFI_X` wrappers, `Foreign<X>` impls, codec changes, or expanding an existing wrapper to cover more of a trait's surface. Also use when reviewing PRs that touch this crate.
+---
+
+# DataFusion FFI Skill
+
+This crate exposes a stable C ABI for DataFusion traits so that independently-compiled libraries (different Rust versions, plugins, `datafusion-python`, etc.) can interoperate at runtime. Stability and correctness here are load-bearing: a missed pattern can cause segfaults, leaks, or silently dropped trait behavior on the consumer side.
+
+Read the crate's `README.md` first if you have not — it establishes the vocabulary (`FFI_X` / `ForeignX`, `library_marker_id`, `release`, `TaskContextProvider`, stabby vs `#[repr(C)]`).
+
+## When to use
+
+Trigger this skill any time the work touches `datafusion/ffi/`:
+
+- Adding a new `FFI_<Trait>` + `Foreign<Trait>` pair
+- Adding a method to an existing `FFI_X` struct
+- Reviewing a PR that touches this crate
+- Changing the codec / proto serialization layer
+- Bumping the wrapped DataFusion trait surface (e.g. a new default method appeared upstream)
+
+## Hard rules
+
+1. **No `datafusion` dependency.** `datafusion-ffi` must not depend on the umbrella `datafusion` crate. Use the leaf crates (`datafusion-common`, `datafusion-expr`, `datafusion-catalog`, `datafusion-physical-plan`, etc.). `datafusion` is fine in `[dev-dependencies]`.
+2. **`#[repr(C)]` on every `FFI_X` struct**, not `#[stabby::stabby]`. Stabby is used for `SString`/`SVec` only. Reasons documented in the README (build time, Arrow types lack `IStable`).
+3. **`unsafe extern "C"` on every function-pointer field — including `version`.** The one exception is the `library_marker_id` field, which is plain `extern "C" fn() -> usize`. Plain (safe) `extern "C"` also applies to the standalone function defs in `src/lib.rs` — `pub extern "C" fn version()` and `pub extern "C" fn get_library_marker_id()` — which coerce into the `unsafe extern "C"` `version` field slot at construction.
+4. **Match `Send`/`Sync` to the wrapped trait.** Raw `*mut c_void` makes every `FFI_X` `!Send + !Sync` by default — `unsafe impl` whichever bounds the consumer-facing trait requires. Most DataFusion traits (`TableProvider`, `ExecutionPlan`, all UDFs, codecs) need both. `Send`-only: `RecordBatchStream`, `Accumulator`, `GroupsAccumulator`, `PartitionEvaluator` (mutable / stream APIs). The matching `ForeignX` always carries the same bounds — pick consistently.
+5. **`#![deny(clippy::clone_on_ref_ptr)]`** is on at the crate root. Use `Arc::clone(&x)`, never `x.clone()` on `Arc`.
+6. **Run before pushing:** `cargo fmt --all`, `cargo clippy -p datafusion-ffi --all-targets --all-features -- -D warnings`, `cargo test -p datafusion-ffi`.
+7. **`api change` label required.** Any PR that modifies an `FFI_X` struct layout (adds/removes/reorders fields, changes a function-pointer signature, adds a variant to an FFI enum, or changes the `version` extern) must carry the `api change` GitHub label. Layout changes break ABI for already-compiled consumer libraries. The label is the project-wide convention for highlighting breaking public-API changes in release notes — see `docs/source/contributor-guide/api-health.md` §"What to do when making breaking API changes?" (step 1 names the label explicitly). Downstream users (e.g. `datafusion-python`, plugin authors) read the labelled notes to know they must recompile against the new DataFusion major. The `version()` extern in `src/lib.rs` returns the major of workspace `CARGO_PKG_VERSION`; consumers compare it at load time and can refuse mismatched producers. Apply via `gh pr edit <num> --add-label "api change"` (label name contains a space — must be quoted). When reviewing such a PR, block merge until label present.
+8. **No FFI struct changes in patch releases.** Patch releases ship from branches matching `^branch-\d+$` (e.g. `branch-53`, `branch-52`). FFI struct layout changes (anything that would earn rule 7's `api change` label) **must not** target a release branch and must not be back-ported. Patch releases are ABI-stable by contract — a consumer compiled against `53.1.0` must keep working against `53.1.1`. Before reviewing/approving an FFI PR, check the PR's base branch: if it matches the regex above, or the PR description / labels indicate patch / back-port, reject the FFI struct change and ask the author to retarget `main`. Bugfixes that do not alter struct layout (e.g. fixing a function-pointer body) are fine to back-port. Quick check: `gh pr view <num> --json baseRefName,labels --jq '.baseRefName'` then match against `^branch-\d+$`. Do **not** glob-match `branch-*` — back-port / cherry-pick working branches (e.g. `branch-53-cherry-pick-1`) also share that prefix but are not release branches; only the strict `branch-<digits>` form is the freeze target.
+
+## The standard wrapper shape
+
+A new `FFI_X` for trait `X` must follow this template. Use `FFI_CatalogProvider` (`src/catalog_provider.rs`) as the canonical reference — it shows the full shape (codec field, nested FFI types, `FFI_Option`/`FFI_Result` returns, Arc-backed `PrivateData`) without async or capability-flag noise. `FFI_TableProvider` (`src/table_provider.rs`) covers async (`scan`, `FFI_SessionRef`, `FfiFuture`) and the one `Option<fn>` capability flag (`supports_filters_pushdown`).
+
+### 1. The `FFI_X` struct
+
+```rust
+#[repr(C)]
+#[derive(Debug)]
+pub struct FFI_X {
+    some_method: unsafe extern "C" fn(this: &Self, ...) -> FFI_Result<...>,
+    optional_method: Option<unsafe extern "C" fn(&Self, ...) -> FFI_Result<...>>,
+    pub logical_codec: FFI_LogicalExtensionCodec,
+
+    clone: unsafe extern "C" fn(&Self) -> Self,
+    release: unsafe extern "C" fn(&mut Self),
+    pub version: unsafe extern "C" fn() -> u64,
+
+    private_data: *mut c_void,
+    pub library_marker_id: extern "C" fn() -> usize,
+}
+
+unsafe impl Send for FFI_X {}
+unsafe impl Sync for FFI_X {}
+```
+
+Field rules:
+
+- **One `unsafe extern "C" fn` per trait method.** Always populate — `Arc<dyn Trait>` dispatch picks override-or-default at call time, so the producer side gets the right answer without the consumer needing to know. See § "Method coverage".
+- **`Option<fn>` is the capability-flag exception**, not a template. Crate uses it exactly once: `FFI_TableProvider::supports_filters_pushdown`. See § "Method coverage".
+- **Codec field** (`FFI_LogicalExtensionCodec` / `FFI_PhysicalExtensionCodec`) only if the trait moves `Expr`s / `LogicalPlan`s / `ExecutionPlan`s across the boundary.
+- **Method function pointers are private by default.** Mark `pub` only if a downstream library needs to invoke them directly (rare — typically only `version`, `library_marker_id`, embedded codecs are `pub`).
+- **`version: super::version` is mandatory.** Consumers gate compatibility on it.
+- **`library_marker_id: crate::get_library_marker_id` is mandatory *when the wrapper uses the standard `ForeignX` adapter pattern*.** Two flavors exist:
+  - **Arc-backed (immutable / shareable traits — `TableProvider`, `ExecutionPlan`, all UDFs, codecs):** consumer-side `From<&FFI_X> for Arc<dyn X>` consults the marker to choose `Arc::clone(inner)` vs `Arc::new(ForeignX(...))`.
+  - **Box-backed (mutable / move-only traits — `Accumulator`, `GroupsAccumulator`, `PartitionEvaluator`):** consumer-side `From<FFI_X> for Box<dyn X>` consults the marker to take the inner `Box` directly vs `Box::new(ForeignX(...))`. Producer-side `From<Box<dyn X>> for FFI_X` *also* uses an `is::<ForeignX>()` downcast as an additional re-wrap bypass; the marker check covers the reverse direction.
+
+  The field is dead ABI surface — and must be omitted with a one-line module-doc rationale — only when **neither** flavor applies: no `ForeignX` adapter, no reverse `From<FFI_X> for {Arc,Box}<dyn X>`, and the trait is impl'd directly on `FFI_X`. Canonical example: `FFI_RecordBatchStream` (`impl RecordBatchStream for FFI_RecordBatchStream` at `record_batch_stream.rs:149`, no `ForeignRecordBatchStream`, no reverse `From`).
+
+  Before flagging a missing `library_marker_id` as a gap, run all three greps on the wrapper file: `Foreign<wrapper-name>`, `From<&?FFI_X> for Arc<`, `From<FFI_X> for Box<`. Hit on any → marker is required and its absence is a real gap. Zero hits on all three → marker is intentionally not needed, not a gap.
+- **`Send`/`Sync` bounds match the wrapped trait** (rule 4). Most wrappers want both; `Send`-only for streams / mutable traits.
+
+### 2. `PrivateData` shape
+
+Default — for read-only, shareable traits — use `Arc`:
+
+```rust
+struct XPrivateData {
+    inner: Arc<dyn X>,
+    runtime: Option<Handle>, // include when any async method exists
+}
+```
+
+For traits that require `&mut self` (e.g. `Accumulator`, `GroupsAccumulator`, `PartitionEvaluator`), use `Box<dyn X>`:
+
+```rust
+struct XPrivateData {
+    inner: Box<dyn X>,
+    runtime: Option<Handle>, // include when any async method exists
+}
+```
+
+A `Box`-backed `FFI_X` **cannot implement `Clone`**; document this and skip the `clone` function pointer, or hand-write a release path that distinguishes producer vs consumer side. Canonical example: `FFI_Accumulator` in `src/udaf/accumulator.rs`. See also `FFI_GroupsAccumulator` (`src/udaf/groups_accumulator.rs`) and `FFI_PartitionEvaluator` (`src/udwf/partition_evaluator.rs`).
+
+### 3. Function-pointer wrappers
+
+Naming convention: `<method>_fn_wrapper`.
+
+```rust
+unsafe extern "C" fn some_method_fn_wrapper(this: &FFI_X, ...) -> FFI_Result<T> {
+    // 1. Recover inner via this.inner()
+    // 2. Translate FFI types → native types
+    // 3. Call native method
+    // 4. Translate native Result → FFI_Result via sresult_return! or .into()
+}
+```
+
+### 4. `clone` / `release` / `Drop`
+
+```rust
+unsafe extern "C" fn clone_fn_wrapper(this: &FFI_X) -> FFI_X { /* re-Box new private_data, copy fn ptrs */ }
+
+unsafe extern "C" fn release_fn_wrapper(this: &mut FFI_X) {
+    unsafe {
+        debug_assert!(!this.private_data.is_null());
+        drop(Box::from_raw(this.private_data as *mut XPrivateData));
+        this.private_data = std::ptr::null_mut();
+    }
+}
+
+impl Drop for FFI_X { fn drop(&mut self) { unsafe { (self.release)(self) } } }
+impl Clone for FFI_X { fn clone(&self) -> Self { unsafe { (self.clone)(self) } } }
+```
+
+`release` must null `private_data` so a double-free debug-asserts loudly.
+
+### 5. Constructor split
+
+```rust
+impl FFI_X {
+    pub fn new(inner: Arc<dyn X>, runtime: Option<Handle>,
+               task_ctx_provider: impl Into<FFI_TaskContextProvider>,
+               logical_codec: Option<Arc<dyn LogicalExtensionCodec>>) -> Self {
+        // build FFI_LogicalExtensionCodec from defaults, then forward
+        Self::new_with_ffi_codec(inner, runtime, ffi_codec)
+    }
+
+    pub fn new_with_ffi_codec(inner: Arc<dyn X>, runtime: Option<Handle>,
+                              logical_codec: FFI_LogicalExtensionCodec) -> Self {
+        // Round-trip downcast: if inner is already a ForeignX, return its FFI directly.
+        if let Some(foreign) = inner.downcast_ref::<ForeignX>() {
+            return foreign.0.clone();
+        }
+        // …allocate XPrivateData and populate fn ptrs…
+    }
+}
+```
+
+The round-trip downcast is **mandatory** — without it, repeated FFI hops nest `ForeignX(FFI_X(ForeignX(...)))` and you pay the boundary cost every layer.
+
+### 6. The `Foreign<X>` consumer
+
+```rust
+#[derive(Debug)]
+pub struct ForeignX(pub FFI_X);
+unsafe impl Send for ForeignX {}
+unsafe impl Sync for ForeignX {}
+
+impl From<&FFI_X> for Arc<dyn X> {
+    fn from(p: &FFI_X) -> Self {
+        if (p.library_marker_id)() == crate::get_library_marker_id() {
+            Arc::clone(unsafe { p.inner() })
+        } else {
+            Arc::new(ForeignX(p.clone()))
+        }
+    }
+}
+
+impl X for ForeignX { /* call each fn pointer, translate types back */ }
+```
+
+The marker-id check is **mandatory** for every `From<&FFI_X> for Arc<dyn X>`. Skipping it breaks the local-bypass optimization and forces the producer's data through serialization.
+
+### 7. Tests
+
+The crate has **two distinct test surfaces** and a new wrapper usually needs entries in both. They are not interchangeable; they catch different classes of bug.
+
+#### a. In-process unit tests (`#[cfg(test)] mod tests` inside `src/<mod>.rs`)
+
+Run on every `cargo test -p datafusion-ffi`. Producer and consumer live in the same compilation unit, so `library_marker_id` returns the same value on both sides. To force the foreign path you must override the marker:
+
+```rust
+let mut ffi_x = FFI_X::new(provider, …);
+ffi_x.library_marker_id = crate::mock_foreign_marker_id; // forces the ForeignX branch
+let arc: Arc<dyn X> = (&ffi_x).into();
+assert!(arc.downcast_ref::<ForeignX>().is_some());
+```
+
+Every wrapper must include at minimum:
+
+- A **local-bypass test** — build `FFI_X` from a concrete native type, convert to `Arc<dyn X>`, `downcast_ref::<ConcreteType>()` must succeed.
+- A **forced-foreign test** — set `library_marker_id = crate::mock_foreign_marker_id`, convert, `downcast_ref::<ForeignX>()` must succeed, then exercise every method end-to-end.
+
+Templates: `test_ffi_table_provider_local_bypass` and `test_round_trip_ffi_table_provider_scan` in `src/table_provider.rs`.
+
+What unit tests catch: Rust-level correctness (translation logic, lifetime bugs, leaks under valgrind/miri, Send/Sync, error propagation, codec round-trips). What they **cannot** catch: real ABI bugs. Both producer and consumer share `#[repr(C)]` layout because they are the exact same struct definition in memory.
+
+#### b. Cross-library integration tests (`tests/ffi_*.rs`, gated by the `integration-tests` feature)
+
+The crate is published as `crate-type = ["cdylib", "rlib"]`. The integration tests in `datafusion/ffi/tests/` use `libloading` to `dlopen` the crate's own `cdylib` and call `datafusion_ffi_get_module` — a `#[unsafe(no_mangle)] extern "C"` entry point defined in `src/tests/mod.rs` and gated by `#[cfg(feature = "integration-tests")]`. The test executable links against the rlib (consumer side); the dlopen'd cdylib is the producer side. Even though both are built from the same source, they are independent compilation outputs going through the actual FFI symbol path.
+
+Run with:
+
+```bash
+cargo test -p datafusion-ffi --features integration-tests
+```
+
+To add coverage for a new wrapper:
+
+1. **Add a constructor** in `src/tests/<area>.rs` (or a new file there). Return a populated `FFI_X` from a known-good native type.
+2. **Wire it into `ForeignLibraryModule`** in `src/tests/mod.rs`: add a field of type `extern "C" fn(...) -> FFI_X` and populate it in `datafusion_ffi_get_module`. This struct is the cross-library contract — adding a field is itself an ABI change for the test module; integration tests will rebuild the cdylib automatically.
+3. **Add the test** in `tests/ffi_<area>.rs` under `#[cfg(feature = "integration-tests")] mod tests { … }`. Call `datafusion_ffi::tests::utils::get_module()` to load the cdylib, invoke your constructor through the returned `ForeignLibraryModule`, convert into `Arc<dyn X>`, and exercise every method.
+
+What integration tests catch that unit tests cannot:
+
+- **Real ABI layout bugs.** Two builds means the consumer's view of `FFI_X` is reconstructed from declaration, not aliased to the producer's memory. Mismatched alignment, padding, niche optimization, or accidentally non-`#[repr(C)]` types surface here.
+- **Symbol visibility / `no_mangle`** issues.
+- **`library_marker_id` correctness without mocking** — the two libraries genuinely have different statics, so the foreign branch is taken for real.
+- **Drop / leak ordering** when the producer side is in a `dlopen`'d image.
+
+#### Which tests does my change need?
+
+| Change                                                                | Unit | Integration |
+| --------------------------------------------------------------------- | ---- | ----------- |
+| New `FFI_X` wrapper                                                   | Yes  | Yes         |
+| New method on existing `FFI_X`                                        | Yes  | Yes if the method takes/returns a non-trivial FFI type. See note below. |
+| Bugfix to a wrapper body, no signature change                         | Yes  | Only if reproducing the bug requires cross-library symbol lookup or `dlopen` semantics |
+| Layout change (`#[repr(C)]` field add/remove/reorder, fn-ptr sig)     | Yes  | **Mandatory** — this is exactly the bug class integration tests exist for |
+| New `From<X> for FFI_X` or codec change                               | Yes  | Yes if the codec is exercised by the cross-library round-trip |
+
+**"Non-trivial FFI type" for the table above** — anything other than:
+
+- Primitives (`u8`/`u64`/`bool`/`usize`, etc.) and `#[repr(u8)]` FFI enums (`FFI_TableType`, `Volatility`, `InsertOp`, `TableProviderFilterPushDown`).
+- A `stabby::string::String` (`SString`) returned by value, with no other args or returns.
+
+Concrete skippable example: `fn name(&self) -> SString` reading a field already validated by another method. Concrete *non*-skippable examples: anything returning `SVec<T>`, `FFI_Option<T>`, `FFI_Result<T>`, `WrappedSchema`, `WrappedArray`, an `FfiFuture`, an `FFI_*` sub-struct, or any `*mut`/`*const` pointer — those exercise alignment / padding / niche-opt across the ABI boundary and need the two-build coverage. When unsure, write the integration test; the cost is one constructor + ~20 lines.
+
+If you skip the integration test for a layout change, you have effectively shipped untested ABI.
+
+## Method coverage — the silent-default gap
+
+**This is the area where the crate currently has real holes.** When the wrapped trait has methods with *default implementations*, those defaults are typically the trait's "no-op / unsupported" answer (`None`, `false`, `Unsupported`, `not_impl_err!()`). If the producer overrides a default but the FFI struct does not carry a function pointer for it, the consumer's `Foreign<X>` falls back to the trait default — **silently losing the override**. The producer thinks it implemented `delete_from`; the consumer behaves as if it never did.
+
+### Rule
+
+When adding or auditing an `FFI_X`, **enumerate every method on the wrapped trait, including defaulted ones**, and for each one decide:
+
+| Category                                                                              | Action                                                                                                                                |
+| ------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------- |
+| Required method (no default)                                                          | Mandatory `unsafe extern "C" fn` field.                                                                                               |
+| Defaulted, plausible override (statistics, distribution, ordering, simplify, DML, …)  | Mandatory `unsafe extern "C" fn` field — same as a required method. The wrapper body calls `inner.method(...)` and `Arc<dyn Trait>` dispatch picks override-or-default for free. |
+| Defaulted, deprecated or vestigial                                                    | Document the skip in a `// FFI omitted: …` comment.                                                                                   |
+| Defaulted, derived purely from other methods already plumbed                          | Skip — but call out the derivation in a comment.                                                                                      |
+
+**Do not use `Option<fn>` just because the underlying trait has a default.** `Arc<dyn Trait>` erases override-vs-default info, so the producer side cannot know whether to populate the slot. Always plumb the fn pointer; the wrapper body invokes the trait method and dynamic dispatch does the right thing.
+
+`Option<fn>` is used exactly once in the crate today: `FFI_TableProvider::supports_filters_pushdown`, gated by the `can_support_pushdown_filters: bool` argument to `FFI_TableProvider::new`. It is an exception, not a template. Reach for it only when (a) the producer's constructor takes an explicit capability flag and (b) skipping the FFI call is meaningfully cheaper than letting the trait default run on the producer side. Otherwise plumb the fn pointer unconditionally.
+
+### Known gaps to close
+
+Tracked gaps live on GitHub under the [`ffi`](https://github.com/apache/datafusion/issues?q=is%3Aissue+is%3Aopen+label%3Affi) label — that query is the source of truth and stays current as issues are filed or closed. Treat new PRs in those areas as opportunities to fix the listed methods; treat new wrappers as required to avoid creating more. Each open issue names the specific wrapper, the missing methods, and the severity.
+
+Quick CLI list:
+
+```bash
+gh issue list --repo apache/datafusion --label ffi --state open --limit 50
+```
+
+Common severity classes seen on the label today:
+
+- **DML / optimizer-relevant defaults silently lost** — e.g. `delete_from`/`update`/`truncate` on table providers, distribution / ordering / pushdown on execution plans, `value_from_stats` on aggregates. These demote producer capability on the foreign side.
+- **SQL surface area silently absent** — naming hooks (`display_name`, `schema_name`, `documentation`), null-handling and within-group clauses on UDAFs, etc.
+- **Performance regressions, not correctness** — e.g. `memoize` on partition evaluators.
+- **Open design questions** — none currently tracked. (Historical entry: whether `FFI_RecordBatchStream` needs `library_marker_id` — resolved no, it impls the trait directly on `FFI_X` with no `Foreign` adapter and no reverse `From`, so the marker has no consultation site. See `library_marker_id` rule in §"Method coverage".)
+
+When in doubt, open the label query; do not assume the list above is exhaustive. Wrappers without an open issue are **not** certified complete — re-enumerate the trait surface (see "How to audit a wrapper's coverage" below) whenever you audit one; upstream trait drift can introduce new defaulted methods at any time and silently re-open the silent-override-loss bug class.
+
+Conversely, an open issue under the `ffi` label is a **claim of a gap, not proof of one.** Past audits have filed false positives by enumerating gaps from memory rather than from current source (e.g. #22335 claimed `size` missing on `FFI_GroupsAccumulator` when it had been plumbed since PR #14775). Before acting on a listed gap — opening a fix PR, re-citing it in a new audit, or extending the list — run the dual-grep audit below and confirm the field is actually absent. If the issue is a false positive, close it as `not planned`, link the `file:line` of the existing plumbing, and remove the corresponding bullet from this skill.
+
+When *closing* a gap, add the fn pointer unconditionally — the wrapper body calls the trait method on the inner `Arc<dyn Trait>` and Rust's dynamic dispatch picks the producer's override or falls back to the default. Use `Option<fn>` only when the new method also gains a corresponding capability flag on the producer's `new()`. Either way the layout changes, so the PR is an ABI break: mark `api change`, do not back-port to `branch-<major>`, and the workspace major bump in the next release makes the `version()` extern surface the change to consumers at load time.
+
+### How to audit a wrapper's coverage
+
+Every audit — opening an issue, filing a fix PR, or re-confirming a listed gap — must compare two sides drawn from current source. Never enumerate either side from memory or from a prior audit; trait surface and FFI struct both drift.
+
+**Side A — trait defaults (what could go missing):**
+
+```bash
+# Find the trait definition
+grep -rn "pub trait X" datafusion/ --include='*.rs'
+
+# Inspect for `fn method(...) { default_body }` — the body marks it as a default
+```
+
+**Side B — FFI wrapper coverage (what is already plumbed):**
+
+```bash
+# List every fn-pointer field on the FFI struct
+grep -nE 'pub [a-z_]+: (unsafe )?extern "C" fn' datafusion/ffi/src/.../X.rs
+```
+
+Diff Side A against Side B. Any claim of a gap — in an issue body, audit summary, or PR description — must cite `file:line` for **both** the trait default and the FFI struct line where the field is (or is not). An issue body with only one side cited is incomplete and likely a false positive; reject it pending a re-grep.
+
+If a method's body is non-trivial, the consumer-side default is non-trivial too. Decide explicitly whether the FFI should let the consumer recompute the same default, or whether the producer's override is what should travel.
+
+## Type-bridging conventions
+
+- **Strings / vecs** crossing the boundary: `stabby::string::String as SString`, `stabby::vec::Vec as SVec`. Native conversion is `Vec::into_iter().collect::<SVec<_>>()` and back.
+- **Optional / fallible** values: use this crate's `FFI_Option<T>` and `FFI_Result<T>` (`src/ffi_option.rs`), *not* stabby's, because ours do not require `T: IStable`.
+- **Schema / arrays**: `WrappedSchema` (`src/arrow_wrappers.rs`) wraps `FFI_ArrowSchema`. Never expose `FFI_ArrowSchema` directly.
+- **Logical `Expr` / `LogicalPlan`**: serialize via `datafusion-proto` using the embedded `FFI_LogicalExtensionCodec`. Same for physical plans → `FFI_PhysicalExtensionCodec`.
+- **Enums** (`Volatility`, `TableType`, `InsertOp`, `TableProviderFilterPushDown`): `#[repr(u8)]`, with `From<Native> for FFI_X` and `From<&FFI_X> for Native`. Always write a round-trip unit test that exercises every variant.
+- **Errors**: every `FFI_X` method that can fail returns `FFI_Result<T>`. Use the `sresult!`, `sresult_return!`, `df_result!` macros from `src/util.rs` — do not roll your own.
+
+## Async, sessions, and task context
+
+- Any async method becomes `unsafe extern "C" fn(...) -> FfiFuture<FFI_Result<T>>`. The wrapper body uses `async move { ... }.into_ffi()`. Store `Option<tokio::runtime::Handle>` in `PrivateData` so the producer side can re-enter its own runtime if needed.
+- Methods taking `&dyn Session` cross the boundary as `FFI_SessionRef`. On the consumer side, try `session.as_local()` first; only construct a `ForeignSession::try_from(&session)` if that returns `None`. See `scan_fn_wrapper` in `src/table_provider.rs`.
+- Anything that needs to deserialize an `Expr` / `LogicalPlan` needs a `TaskContext`. Threading a fresh `TaskContext` per call is wrong because new UDFs may have been registered since construction. Use `FFI_TaskContextProvider` (`src/execution/task_ctx_provider.rs`), which holds a `Weak` ref to a `TaskContextProvider`. If the weak ref is dead at call time, return a clear error — do not panic.
+
+## Memory model checklist for every new `FFI_X`
+
+- [ ] `private_data` is `Box::into_raw`-ed exactly once at construction.
+- [ ] Every constructor path (including `clone_fn_wrapper`) allocates a fresh `Box` for its own `private_data`.
+- [ ] `release_fn_wrapper` `Box::from_raw`s it and nulls the pointer.
+- [ ] `Drop` calls `release`.
+- [ ] No method touches `private_data` directly outside the producer side. Consumer-side methods on `ForeignX` use only the function pointers.
+- [ ] `library_marker_id` and `version` are populated in **every** constructor (including `clone`).
+- [ ] No method dereferences a pointer it did not check for nullness (debug-assert at minimum).
+
+## Quick PR-review checklist
+
+When reviewing a PR that touches `datafusion/ffi/`:
+
+1. **Trait coverage.** Pull up the underlying trait. List its methods. Confirm every non-defaulted method has a function pointer. For each *defaulted* method, ask whether a real-world producer would override it — if yes, the PR must either plumb it through as a plain `unsafe extern "C" fn` (let dynamic dispatch on `Arc<dyn Trait>` pick override-or-default) or explicitly justify the omission in a comment. Reserve `Option<fn>` for the capability-flag pattern described in §"Method coverage" — do not use it just because the trait has a default.
+2. **Layout fields.** `clone`, `release`, `version`, `private_data` all present? `library_marker_id` present **iff** wrapper has a `ForeignX` adapter and a reverse `From<&?FFI_X> for {Arc,Box}<dyn X>` consultation site (Arc-backed for shareable traits, Box-backed for `&mut self` traits); if the trait is impl'd directly on `FFI_X` (no `ForeignX`, no reverse `From`), `library_marker_id` is dead surface and must be omitted with a one-line rationale.
+3. **Marker-id bypass** in `From<&FFI_X>` (where applicable per rule 2)?
+4. **Round-trip downcast** in the constructor?
+5. **`Drop` calling `release`**, and `release` nulling the pointer?
+6. **`Send`/`Sync` unsafe impls** match the wrapped trait's bounds (rule 4), and `FFI_X` + `ForeignX` agree?
+7. **Stabby types** for strings/vecs; crate-local `FFI_Option`/`FFI_Result` for optional/fallible payloads?
+8. **Async** uses `FfiFuture` + `.into_ffi()`, never blocking?
+9. **Codec** present on any method that ships an `Expr` / plan?
+10. **Unit tests** include both local-bypass and `mock_foreign_marker_id` forced-foreign cases? **Integration tests** in `tests/ffi_*.rs` exist for any wrapper that takes/returns non-trivial FFI types, and for *every* layout change? `cargo test -p datafusion-ffi --features integration-tests` must pass before merging an ABI-affecting PR.
+11. **No `datafusion` runtime dep** crept into `Cargo.toml`?
+12. **`Arc::clone(&x)`** everywhere — no implicit `x.clone()` on `Arc` (the lint will reject it but worth pre-flagging).
+13. **`cargo clippy --all-targets --all-features -- -D warnings`** clean on the crate?
+14. **`api change` label** on the PR if any `FFI_X` struct layout / fn-ptr signature / FFI enum / `version` extern changed? Block merge until applied.
+15. **Base branch check.** If FFI struct layout changed, base branch must be `main`, never a release branch matching `^branch-\d+$` (e.g. `branch-53`). Reject back-ports of ABI-breaking changes to patch-release branches. Verify with `gh pr view <num> --json baseRefName,labels --jq '.baseRefName'`; match strictly against `^branch-\d+$` — cherry-pick working branches like `branch-53-cherry-pick-1` also start with `branch-` and must not false-positive.

Subject: [PATCH 027/878] Optimize metric label cloning (#22406)

## Which issue does this PR close?

- Part of #22189.

## Rationale for this change

`ParquetFileMetrics::new` registers many per-file metrics with the same
`filename` label. Before this PR, each metric built its own owned
filename label with `filename.to_string()`, which repeatedly copied the
same dynamic
string during parquet scan setup.

This PR keeps parquet metrics eagerly registered, so
`ExecutionPlan::metrics()` visibility during execution is unchanged,
while reducing repeated label string allocation and copying.

## What changes are included in this PR?

- Store owned `Label` name/value strings behind `Arc<str>` internally,
while
  keeping borrowed static label strings allocation-free.
- Reuse one cloned `filename` label across the per-file parquet metrics
in
  `ParquetFileMetrics::new`.
- Add a metrics test confirming borrowed and owned label values remain
equal
  and display the same way.

## Are these changes tested?

Yes.


## Are there any user-facing changes?

No. Metric registration timing and displayed label values are unchanged.

Subject: [PATCH 028/878] feat: Analyze `VALUES` for nullability (#22089)

## Which issue does this PR close?

- Closes #22088.

## Rationale for this change

`LogicalPlanBuilder::infer_data` (the inference path for `VALUES`
clauses without a target schema) hard-coded every inferred column's
nullability to `true`, regardless of whether any row actually contained
a NULL. This is inconsistent with how nullability is computed for other,
similar situations (e.g., `SELECT 1`).

In addition to improving internal consistency (and theoretically
allowing better query optimization), this also makes it easier to write
tests for nullability-related behavior without using a scratch table.

## What changes are included in this PR?

* `LogicalPlanBuilder::infer_data` now tracks per-column nullability
while iterating values, marking the column nullable iff any row's value
expression returns `nullable() == true`. Note that this only changes
behavior for `VALUES` without a schema; `INSERT INTO VALUES`, for
example, already computed nullability.
* Add SLT tests for this behavior
* Update expected SLT tests where this change results in updating a
schema. Note that some Parquet files are slightly smaller now, which
caused byte-count metrics in a few places to change.


## Are these changes tested?

Yes, with new tests added.

## Are there any user-facing changes?

The inferred schema for `CREATE TABLE AS VALUES (...)` will now change,
although if we also fix #22087 then the original behavior will be
preserved.

Subject: [PATCH 029/878] Add EnsureRequirements: merged EnforceDistribution +
 EnforceSorting with idempotent pushdown_sorts (#21976)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

Replace the separate `EnforceDistribution` and `EnforceSorting`
optimizer rules with a single `EnsureRequirements` rule in the default
optimizer chain. Fix `pushdown_sorts` to be distribution-aware and fix
the `SortPreservingMergeExec` / `CoalescePartitionsExec` fetch
preservation issue from #14150, making the composition idempotent.

**Epic**: #21973

Closes: #14150

## Problem

`EnforceDistribution` and `EnforceSorting` run as separate rules, but
sorting and distribution are coupled through
`SortExec.preserve_partitioning`. This caused:

1. **`SanityCheckPlan` validation failures on multi-partition sort +
limit** — `pushdown_sorts` set `preserve_partitioning=true` on
multi-partition input without inserting `SortPreservingMergeExec`,
violating the `SinglePartition` requirement coming from
`GlobalLimitExec`.
2. **Non-idempotent composition** — running the rules multiple times
produced different (sometimes invalid) plans.
3. **Lost fetch values (#14150)** — `EnforceDistribution` dropped
`fetch` from `SortPreservingMergeExec` / `CoalescePartitionsExec` when
stripping and re-adding distribution operators.

DataFusion was the only major query engine with separate rules — Spark
(`EnsureRequirements`) and Presto/Trino (`AddExchanges`) handle both in
a single rule.

## Changes

### 1. `EnsureRequirements` rule (new, replaces `EnforceDistribution` +
`EnforceSorting` in the default chain)
- Single `PhysicalOptimizerRule` that calls the distribution + sorting
helpers in one coordinated bottom-up sequence.
- Registered in place of `Arc::new(EnforceDistribution) +
Arc::new(EnforceSorting)` in the default optimizer chain.
- Comprehensive inline tests covering known bug topologies + idempotency
verification.

### 2. Distribution-aware `pushdown_sorts` (`sort_pushdown.rs`)
- Add `distribution_requirement: Distribution` field to
`ParentRequirements`.
- New `add_sort_above_with_distribution()` in `utils.rs` — inserts
`SortPreservingMergeExec` when the parent requires `SinglePartition` and
the input has multiple partitions.
- Switch both `add_sort_above` call sites to the distribution-aware
variant.
- Propagate distribution through recursion with a
`stronger_distribution()` helper.
- Reset distribution below partition-merging nodes (SPM,
single-partition outputs).

### 3. Fix fetch preservation in distribution enforcement (#14150)
- `remove_dist_changing_operators()` now saves `fetch` from removed SPM
/ Coalesce nodes.
- `add_merge_on_top()` re-applies the saved `fetch` to re-created
operators.

### 4. Retire the old rule entry points; retarget existing tests
After review feedback from @alamb
(https://github.com/apache/datafusion/pull/21976#issuecomment-4432397769),
the rule structs and their `impl PhysicalOptimizerRule` blocks have been
deleted from `enforce_distribution.rs` and `enforce_sorting/mod.rs`. The
internal helpers (`ensure_distribution`, `ensure_sorting`, the contexts,
`parallelize_sorts`, `replace_with_order_preserving_variants`,
`sort_pushdown`, …) stay in place — `EnsureRequirements` calls them
directly.

The existing integration tests in `core/tests/physical_optimizer/` now
exercise `EnsureRequirements` instead of the deleted rules:
- `enforce_distribution.rs` — `Run::Distribution` / `Run::Sorting`
branches both call `EnsureRequirements::new()`. Legacy run sequences
(`DISTRIB_DISTRIB_SORT`, `SORT_DISTRIB_DISTRIB`) are preserved verbatim;
idempotency makes the previously-different orderings converge to the
same plan.
- `enforce_sorting.rs` — `EnforceSortingTest` drives
`EnsureRequirements::new()` and pins `target_partitions = 10` so
snapshots are deterministic across machines. The historical `[Dist,
Sort]` vs `[Sort, Dist, Sort]` comparison is rewritten as "running
`EnsureRequirements` N times == running it once".
- `enforce_sorting_monotonicity.rs` /
`replace_with_order_preserving_variants.rs` — driven through the same
test framework; only snapshots updated.

A previously-separate `ensure_requirements/new_tests.rs` (added in an
earlier iteration of this PR) is removed; the same coverage lives in the
inline tests in `ensure_requirements/mod.rs`.

### 5. Updated SLT
- `explain.slt`: `EnforceDistribution` + `EnforceSorting` collapse to
`EnsureRequirements` in `EXPLAIN VERBOSE` output.

## Snapshot drift

~78 snapshots in the retargeted tests refreshed. The consistent pattern
is `SortExec + CoalescePartitionsExec` (blocking) →
`SortPreservingMergeExec` (streaming), because `EnsureRequirements` now
runs `parallelize_sorts` + `replace_with_order_preserving_variants` on
plan shapes that the single-rule path used to miss. These are
improvements, not regressions — but worth a careful look in review since
they are visible in the diff.

## Testing

| Suite | Result |
|-------|--------|
| `datafusion-physical-optimizer` (lib, inline tests) | **59 passed** |
| `core_integration physical_optimizer::` | **454 passed** |
| `cargo clippy --all-targets -- -D warnings` | clean |
| `cargo fmt --all --check` | clean |

### Idempotency / regression coverage in the inline tests

| Scenario | Covered |
|----------|---------|
| Multi-partition sort + limit (1-64 partitions) | yes |
| Union with mixed partition counts | yes |
| Projection over multi-partition | yes |
| HashJoin (Partitioned) | yes |
| SortMergeJoin | yes |
| Window function partitioning + ordering | yes |
| Aggregate (Partial + FinalPartitioned) | yes |
| Nested sort + limit | yes |
| Hash repartition + sort | yes |
| CoalescePartitions + sort (`parallelize_sorts`) | yes |
| SPM → Sort → multi-partition | yes |
| `OutputRequirementExec` + `SinglePartition` over multi-partition
source | yes |
| `ProjectionExec` + multi-partition + `SinglePartition` requirement |
yes |
| #14150 fetch preservation across passes | yes |
| Triple optimization convergence | yes |
| 10× consecutive optimization stability | yes |

## Architecture

```
EnsureRequirements::optimize(plan)
  Phase 1: join key reordering (top-down) — adjust_input_keys_ordering
           or reorder_join_keys_to_inputs depending on config.
  Phase 2: distribution enforcement (bottom-up) — ensure_distribution
           Fetch is preserved across SPM/Coalesce strip/re-add (#14150 fix).
  Phase 3: sort enforcement (bottom-up) — ensure_sorting
  Phase 4: parallelize_sorts (bottom-up, when repartition_sorts is on)
  Phase 5: replace_with_order_preserving_variants (bottom-up)
  Phase 6: pushdown_sorts (top-down, distribution-aware)
  Phase 7: replace_with_partial_sort (bottom-up)
```

Idempotent because:
- `pushdown_sorts` now carries `distribution_requirement` and uses
`add_sort_above_with_distribution`, so the second pass never re-violates
an earlier-established `SinglePartition` requirement.
- Distribution enforcement preserves `fetch` across strip/re-add cycles.
- Running `EnsureRequirements` repeatedly converges (verified across the
partition-count sweep, hash-join, sort-merge join, window, projection,
and #14150 regression tests).

## Next steps (future PRs)

- Gradually fold `pushdown_sorts` work into the bottom-up
`ensure_sorting` pass.
- Eliminate the separate top-down `pushdown_sorts` traversal.
- Single-pass architecture (one `transform_up` for both distribution +
sorting, like Spark's `EnsureRequirements`).

+
+//! [`EnsureRequirements`] optimizer rule that enforces distribution and
+//! sorting requirements together so that the two never invalidate each other.
+//!
+//! This rule replaces the separate `EnforceDistribution` + `EnforceSorting`
+//! rules with a unified approach inspired by Apache Spark's `EnsureRequirements`
+//! and Presto/Trino's `AddExchanges`.
+//!
+//! # Motivation
+//!
+//! The previous two-rule design (`EnforceDistribution` then `EnforceSorting`)
+//! suffers from non-idempotent composition: `EnforceSorting`'s `pushdown_sorts`
+//! can break distribution invariants established by `EnforceDistribution`,
+//! because `SortExec.preserve_partitioning` couples sorting and distribution
+//! decisions. See <https://github.com/apache/datafusion/issues/21973> for details.
+//!
+//! # Architecture
+//!
+//! `optimize` runs several tree traversals. The defining property of this
+//! rule is **Phase 2**: a single combined bottom-up pass that resolves
+//! distribution *and* sorting for each node together. The surrounding phases
+//! are independent traversals (top-down join-key reorder, then several
+//! follow-up sort/order rewrites). Some of those could be consolidated
+//! further in a follow-up.
+//!
+//! ```text
+//! EnsureRequirements::optimize(plan)
+//! │
+//! ├─ Phase 1: top-down join-key reorder        (adjust_input_keys_ordering)
+//! │
+//! ├─ Phase 2: combined distribution + sorting  (single bottom-up pass)
+//! │   └─ For each node (bottom-up), for each child:
+//! │       Step 1: ensure distribution requirement
+//! │         └─ insert RepartitionExec / CoalescePartitionsExec /
+//! │            SortPreservingMergeExec as needed
+//! │       Step 2: ensure ordering requirement (distribution-aware)
+//! │         └─ insert SortExec with the correct `preserve_partitioning`,
+//! │            with SortPreservingMergeExec on top if needed
+//! │
+//! └─ Phase 3: small follow-up passes (bottom-up unless noted)
+//!     ├─ parallelize_sorts
+//!     ├─ replace_with_order_preserving_variants
+//!     ├─ pushdown_sorts                         (recursive walk)
+//!     └─ replace_with_partial_sort
+//! ```
+//!
+//! # Key Properties
+//!
+//! - **Idempotent across the whole rule**: Running `EnsureRequirements`
+//!   twice produces the same plan. This is the property that fixes
+//!   <https://github.com/apache/datafusion/issues/21973>, where the old
+//!   two-rule pipeline could regress a parallel sort plan into a serial one
+//!   on pass 2.
+//! - **Distribution before sorting**: For each child, distribution is
+//!   resolved before ordering, so sorting decisions always have full
+//!   distribution context.
+//! - **Sort pushdown is implicit**: Phase 2 only adds `SortExec` where the
+//!   child doesn't already satisfy the ordering requirement, so sorts land
+//!   at the deepest valid position without a separate destructive pass.
+//!
+//! # Behavior: parallelism via repartitioning
+//!
+//! Phase 2 Step 1 inserts `RepartitionExec` to satisfy distribution
+//! requirements. When configuration allows, it also increases parallelism by
+//! repartitioning over otherwise-serial inputs. For example, given two
+//! 1-partition inputs feeding an operator that can run with more
+//! parallelism:
+//!
+//! ```text
+//! ┌─────────────────────────────────┐
+//! │          ExecutionPlan          │
+//! └─────────────────────────────────┘
+//!         ▲                 ▲
+//!         │                 │
+//!   ┌───────────┐     ┌───────────┐
+//!   │  batch A  │     │  batch B  │      Input: 2 partitions
+//!   └───────────┘     └───────────┘
+//! ```
+//!
+//! `EnsureRequirements` inserts a `RepartitionExec` so the operator runs
+//! with three partitions:
+//!
+//! ```text
+//! ┌─────────────────────────────────┐
+//! │          ExecutionPlan          │      Input now has 3 partitions
+//! └─────────────────────────────────┘
+//!         ▲      ▲       ▲
+//!         └──────┼───────┘
+//!                │
+//! ┌─────────────────────────────────┐
+//! │       RepartitionExec(3)        │      batches are repartitioned
+//! │           RoundRobin            │
+//! └─────────────────────────────────┘
+//!         ▲                 ▲
+//!   ┌───────────┐     ┌───────────┐
+//!   │  batch A  │     │  batch B  │
+//!   └───────────┘     └───────────┘
+//! ```
+//!
+//! # Behavior: joint distribution + sorting
+//!
+//! Resolving distribution and sorting together lets Phase 2 produce a
+//! parallel sort plan in cases where the two-rule pipeline historically
+//! risked a serial one. Given `Sort(DESC) ← Coalesce ← MultiPartitionSource`,
+//! `EnsureRequirements` rewrites it into:
+//!
+//! ```text
+//! SortPreservingMergeExec: [a DESC]            (cheap k-way merge of sorted streams)
+//!   SortExec: [a DESC], preserve_partitioning=true   (N sorts run in parallel)
+//!     MultiPartitionSource
+//! ```
+//!
+//! Each input partition is sorted in parallel, then a `SortPreservingMergeExec`
+//! at the top performs a cheap merge of pre-sorted streams. For TopK queries
+//! (`fetch=K`), each parallel sort only keeps K rows per partition, so total
+//! memory is `N × K` rather than coalescing the entire stream first.
+//!
+//! # Behavior: strictest distribution match for joins
+//!
+//! Distribution requirements are met in the strictest way. For example, a
+//! hash join with keys `(a, b, c)` requires `Distribution(a, b, c)`. This
+//! can in principle be satisfied by partitioning on any superset of any
+//! subset of `(a, b, c)`, but this rule always partitions on the exact key
+//! tuple `(a, b, c)`. This is sometimes more aggressive than strictly
+//! necessary, but the strictest match helps avoid data skew in joins.
+

+// in `core/tests/physical_optimizer/{enforce_distribution,enforce_sorting}.rs`.

Subject: [PATCH 030/878] Support DISTINCT ON with aggregation and windows
 (#22169)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #17256.

## Rationale for this change

DataFusion currently rejects `DISTINCT ON` queries when they are
combined with `GROUP BY`, aggregate functions, or window functions.

PostgreSQL allows these queries. The planner already builds the
aggregate and window plan before applying `DISTINCT ON`, but the old
`DISTINCT ON` path only worked against the pre-aggregation input. That
meant expressions that depended on aggregate or window output could not
be planned.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

This PR updates `DISTINCT ON` planning so its expressions participate in
the same aggregate and window rewrite pipeline as `SELECT`, `HAVING`,
`QUALIFY`, and `ORDER BY`.

It also keeps hidden `DISTINCT ON` keys and `ORDER BY` tie-breakers in
scope before the final projection, so valid PostgreSQL-style queries
work even when those expressions are not in the select list.

The change also handles SELECT alias resolution for `DISTINCT ON` and
`ORDER BY` in the PostgreSQL-compatible way: a bare alias can resolve to
the select expression, while the same name inside a larger expression
still resolves as an input column.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No public API Change
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 031/878] fix: custom_datasource example ignores projection
 pushdown in execute() (#22417)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #18578.

## Rationale for this change

The `custom_data_source` example computes a `projected_schema` from the
projection it receives in `scan`, advertising projection-pushdown
support but its `CustomExec::execute` then always emits both source
columns. As soon as
the planner pushes a non-identity projection (e.g. `SELECT 1 FROM t` →
`Some([])`, `SELECT COUNT(id) FROM t` → `Some([0])`), the RecordBatch's
column count diverges from `projected_schema` and the query fails.



<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

- Store the projection on `CustomExec` so `execute` can apply it.
- In `execute`, build a `RecordBatch` over the full source schema and
use `RecordBatch::project` to drop the columns the planner didn't ask
for.`project` preserves row count, which matters when the projection
selects zero columns (`SELECT 1 FROM t`).
- Extend `custom_datasource()` to register the table with a
`SessionContext` and run `SELECT 1 AS a FROM accounts` and `SELECT
COUNT(id) FROM accounts`, which are the two shapes reported in the
issue.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 032/878] fix: handle `IS TRUE` correctly in
 `EliminateOuterJoin` (#22444)

## Which issue does this PR close?

- Closes #22441.

## Rationale for this change

`EliminateOuterJoin` needs to identify "null-rejecting" columns; a
column is null-rejecting with respect to an expression if a NULL value
in the column yields a NULL or false value for the expression.

This analysis was unsound with respect to `IS TRUE`, `IS FALSE`, and `IS
NOT UNKNOWN` operators: those operators are null-rejecting at the
toplevel of the `WHERE` clause, but they may not be null-rejecting when
nested inside an expression tree. The analysis checked this correctly
for `IS NOT NULL` but neglected to apply similar logic for these other
three operators. This resulted in incorrectly converting outer joins to
inner joins in some cases, producing incorrect query results.

As part of fixing this, this PR also makes a bunch of improvements to
the null-rejection analysis, enumerated below, resulting in more
accurate null-rejection analysis.

## What changes are included in this PR?

* Rename `extract_non_nullable_columns` to
`extract_null_rejecting_columns`: "non_nullable" is a property of a
column, "null-rejecting" is a more complex property describing the
relationship between a column and an expression.
* Use `Operator::returns_null_on_null()` instead of maintaining a
hand-rolled and very incomplete list of null-propagating binary
operators. We now compute null-rejection correctly for arithmetic,
bitwise, and regex operators, for example.
* Handle null-rejection correctly for `Expr::Negative`
* Rewrite the logic for handling `OR` and nested `AND` operators to be
more clear, and also more efficient
* Rewrite and expand comments throughout for clarity
* Add unit and SLT tests

## Are these changes tested?

Yes; new unit and SLT tests added.

## Are there any user-facing changes?

Yes, query result correctness fix.

Subject: [PATCH 033/878] fix: avoid panic in
 TableSchema::with_table_partition_cols on shared Arc (#22372)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- No separate issue. This addresses a review observation from #22026:
https://github.com/apache/datafusion/pull/22026#discussion_r3267880296

## Rationale for this change

`TableSchema::with_table_partition_cols` appended to an existing
partition-column list via `Arc::get_mut(...).expect(...)`. The `expect`
message assumed that owning `self` implies sole ownership of the inner
`Arc<Vec<FieldRef>>` — but that is not true. `TableSchema` derives
`Clone`, and cloning only bumps the `Arc` refcount without copying the
`Vec`.

So this sequence panicked:

```rust
let ts = TableSchema::new(file_schema, vec![some_partition_col]);
let cloned = ts.clone();                       // Arc refcount is now 2
let _ = cloned.with_table_partition_cols(more); // Arc::get_mut -> None -> expect() panics
```

`with_table_partition_cols` taking `mut self` gives unique ownership of
the *struct*, not of the inner `Arc`.

## What changes are included in this PR?

- Make `with_table_partition_cols` **replace** the partition columns
instead of appending to them, by assigning a fresh
`Arc::new(partition_cols)`. This removes the in-place mutation branch
entirely:
- It never mutates the inner `Vec`, so it is safe even when the `Arc` is
shared with a clone (copy-on-write isolation is automatic) — fixing the
panic without needing `Arc::make_mut`.
- It matches builder-API expectations (a `with_x` setter replaces) and
removes the risk of accidentally duplicating partition columns, as
raised in review.
- No production code relied on the append behavior (every `TableSchema`
is built via `new`/`from_file_schema`); only unit tests exercised it,
and they are updated to assert replacement.

## Are these changes tested?

Yes:
- `test_with_table_partition_cols_replaces_existing` verifies that
calling the method on a `TableSchema` that already has partition columns
replaces them rather than appending.
- `test_with_table_partition_cols_after_clone_does_not_panic` clones a
`TableSchema` and sets partition columns on the clone, verifying it does
not panic and that the other clone is left unmodified (copy-on-write
isolation).

Existing `TableSchema` tests continue to pass.

## Are there any user-facing changes?

`TableSchema::with_table_partition_cols` now replaces existing partition
columns instead of appending to them. The previous append path panicked
on any shared/cloned `TableSchema`, so no working usage relied on it.
There are no API signature changes.

Subject: [PATCH 034/878] Benchmark multi-column GROUP BY performance (#22322)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

  - Measuring: https://github.com/apache/datafusion/issues/17850

  ## Rationale for this change

1. Measure multi-column GROUP BY performance with a fair
apples-to-apples comparison
2. The default vectorized per-column approach (`GroupValuesColumn`)
underperforms the row-based approach (`GroupValuesRows`) when distinct
group count is small relative
to input rows. The benchmark confirms this: row-based is 16-19% faster
below ~200K groups, while vectorized wins by 15-33% above ~500K groups.

  ## What changes are included in this PR?

Adds a benchmark in `datafusion/physical-plan/benches/multi_group_by.rs`
that directly calls `GroupValues::intern()` with identical Int32 data
for both implementations —
  no SQL/planning/IO overhead, same schema, same hashing.

Makes `mod row` public so the benchmark can instantiate
`GroupValuesRows` directly.

  Test cases:
- **Issue #17850 reproduction** (3 cols, 64 groups, 1M-50M rows) —
confirms row-based wins ~16-19%
- **Low cardinality sweep** (8-4096 groups, 3-4 cols) — row-based wins
15-38%
  - **Batch size sensitivity** (1K-32K) — minimal effect on ratio
- **Column scaling with low groups** (2-10 cols) — row-based advantage
grows with columns
- **High cardinality scaling** (1M groups, 2-10 cols) — vectorized wins
22-43%
- **Group count sweep** (16 to 1M groups, 4 cols) — crossover at
~200K-500K groups

  ## Are these changes tested?

  - `cargo fmt --all`
- `cargo clippy -p datafusion-physical-plan --bench multi_group_by -- -D
warnings`
  - `cargo bench -p datafusion-physical-plan --bench multi_group_by`

  ## Are there any user-facing changes?

  No. This adds a benchmark only.

Subject: [PATCH 035/878] fix(sort-pushdown): restore SortExec elimination
 after stats-based file reorder (#22493)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22494


Regression introduced by #21956 — single-partition multi-file scans with
`WITH ORDER` (or inferred parquet `sorting_columns` metadata) plus files
listed out of order on disk no longer have their `SortExec` eliminated,
even when the stats-based file reorder produces a non-overlapping
layout.
This was the central case PR #21182 was designed to fix.

## Rationale for this change

In the Phase 2 sort pushdown design (#21182), when a file source
returned
`Unsupported` because `validated_output_ordering()` stripped its
declared
ordering, the outer `FileScanConfig::try_pushdown_sort` invoked a
fallback
(`try_sort_file_groups_by_statistics`) that reordered files by min/max
stats, re-validated the ordering against the new file groups, and could
upgrade the result back to `Exact` — dropping the outer `SortExec`.

PR #21956 added the `column_in_file_schema` signal so that plain-column
sort requests would return `Inexact` (with `sort_order_for_reorder` set)
instead of `Unsupported`. That enabled runtime per-RG reorder, but it
also pulled the typical wrong-file-order case out of the
`Unsupported`-fallback re-validation path. The Inexact branch of
`rebuild_with_source` always strips `output_ordering`, so even when the
post-sort file groups became non-overlapping and the declared ordering
would re-validate, the outer wrapper returned `Inexact` and PushdownSort
kept the `SortExec`.

The SLT comment on test 6.1 (`# … → SortExec eliminated`) still
describes
the pre-#21956 behaviour, but the recorded expectation was updated to
match the post-#21956 plan where SortExec stayed — a silent regression.

## What changes are included in this PR?

### `rebuild_with_source`

When `is_exact=false` but the stats-based file sort produced
`all_non_overlapping=true`, re-validate the declared `output_ordering`
against the new file groups. If `ordering_satisfy` passes, preserve
`output_ordering` instead of stripping it.

### Outer `FileScanConfig::try_pushdown_sort`

On the `Inexact` branch, inspect `config.output_ordering` after rebuild
and return `Exact` if it survived. This restores the
`Unsupported → upgrade Exact` semantics, but on the `Inexact` branch the
plain-column path now follows.

### Safety

- When the source has no declared ordering (no `WITH ORDER` and no
  parquet `sorting_columns` metadata), `self.output_ordering` is empty,
  the re-validate produces no orderings, `ordering_satisfy` returns
  `false`, and `SortExec` stays. min/max stats alone never trigger an
  upgrade.
- When `all_non_overlapping=false` (overlapping files post-sort),
  `output_ordering` is stripped exactly as before.

### Tests

`sort_pushdown.slt`:

- Tests **4.1** (parquet metadata), **6.1** (`WITH ORDER ASC`),
  **8.1** (`WITH ORDER DESC` with reverse), **G.1**, **G.2** (multi-
  partition SPM + BufferExec) — expectations updated to match the
  restored `SortExec`-eliminated plans (matches the PR #21182 era plans
  and the SLT comments that were already in the file).
- New **Test 5b** — files written without `ORDER BY` (no
  `sorting_columns` metadata) + external table without `WITH ORDER`:
  asserts that even when min/max stats happen to be non-overlapping,
  `SortExec` is kept.

## Are these changes tested?

Yes — `sort_pushdown.slt` covers the affected paths comprehensively.
Full `cargo test -p datafusion-sqllogictest --test sqllogictests` and
`cargo test -p datafusion-datasource --lib` / `-p
datafusion-datasource-parquet --lib` / `-p
datafusion-physical-optimizer`
pass. `cargo clippy -D warnings` clean.

## Are there any user-facing changes?

Yes — for the in-scope scenarios above, `EXPLAIN` plans now show the
`SortExec` removed and `output_ordering` set on `DataSourceExec`. Query
results are unaffected.

Subject: [PATCH 036/878] fix array_repeat capacity overflow on constant scalar
 with large count (#22305)

## Which issue does this PR close?

- Closes #22228 .

## Rationale for this change

`array_repeat` still panics for oversized repeat counts in the
constant-scalar path. The simplest reproducer is:

```sql
SELECT array_repeat(1, 9223372036854775807)
```

Unlike the previously reported `array_repeat` overflow cases, this path
does not sum counts across rows and does not multiply nested list
lengths, but it still reaches an unchecked `Vec` preallocation and
panics with `capacity overflow`.

This change makes `array_repeat` reject oversized output lengths up
front and return a normal execution error instead of panicking.

## What changes are included in this PR?

This PR adds explicit bounds checks in repeat.rs so `array_repeat`
validates requested output sizes before allocating buffers.

The main changes are:

- Move repeat-length accumulation into shared checked helpers.
- Reject oversized output lengths with:
  `array_repeat: requested length exceeds maximum array size`
- Guard both scalar and list repeat paths so they fail consistently
before hitting unchecked allocation or arithmetic overflow.
- Reuse precomputed outer offsets for the list path instead of
rebuilding them from unchecked lengths.

## Are these changes tested?

Yes.

This PR adds a regression test in repeat.rs covering the constant-scalar
reproducer with `i64::MAX` as the repeat count and verifies that
`array_repeat` returns an execution error rather than panicking.

Validated with:

```bash
cargo test -p datafusion-functions-nested scalar_count_exceeding_max_array_size_returns_error --lib
```

## Are there any user-facing changes?

Yes.

Previously, oversized `array_repeat` calls could panic the process.
After this change, they return a regular execution error:

```text
array_repeat: requested length exceeds maximum array size
```

Subject: [PATCH 037/878] fix sqrt(-1.0::float8) should error, not return NaN
 (#22308)

## Which issue does this PR close?

- Closes #22260.

## Rationale for this change

DataFusion previously returned `NaN` for `sqrt` on negative
floating-point inputs, for example `sqrt((-1.0)::float8)`. This differs
from PostgreSQL semantics, which raise an error for square root of a
negative number.

This change makes `sqrt` return an execution error for out-of-domain
negative inputs so its behavior is closer to PostgreSQL and avoids
silently producing `NaN` for invalid inputs.

## What changes are included in this PR?

- Updated the unary math UDF helper to support an optional validator
callback for runtime input validation.
- Switched `sqrt` to use a named validator helper instead of inline
predicate and error-string arguments.
- Added runtime validation for `sqrt` so negative inputs now raise
`cannot take square root of a negative number`.
- Updated sqllogictests for `sqrt`:
  - negative literal inputs now expect an error
  - negative column inputs now expect an error
  - positive column coverage was retained using in-domain inputs

## Are these changes tested?

Yes.

The change is covered by existing SQL logic tests and targeted
validation runs:

- `cargo test -p datafusion-functions sqrt`
- `cargo test -p datafusion-sqllogictest --test sqllogictests scalar`

## Are there any user-facing changes?

Yes.

`sqrt` now raises an execution error for negative inputs instead of
returning `NaN`. This changes user-visible query behavior to better
align with PostgreSQL semantics.

Subject: [PATCH 038/878] perf: optimize `array_replace` for scalar needle

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Currently, `array_replace` / `array_replace_n` / `array_replace_all`
perform element-wise comparison by invoking `compare_element_to_list`
against each row's sub-array individually. When the needle is a scalar,
this can be optimized by performing a single vectorized `not_distinct`
comparison over the entire flattened values buffer.



## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add a specialized replacement kernel that uses
`arrow_ord::cmp::not_distinct` with `Scalar` wrapper for a single bulk
comparison pass over the flat values buffer.
- Extend SLT tests with multi-row scalar-argument coverage, empty-array
edge cases, NULL needle replacement, and boundary `n` values for
LargeList/FixedSizeList types.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes, existing and new slt edge-case tests in `array_replace.slt`.

## Are there any user-facing changes?

No.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Rationale**

The `datafusion-spark` crate is missing the `monthname` function.
Spark's
[`monthname(date)`](https://spark.apache.org/docs/latest/api/sql/index.html#monthname)
returns the **three-letter abbreviated month name** (Jan, Feb, ..., Dec)
from a date or timestamp — commonly used in Spark SQL workloads.

**What changes are included in this PR?**

Adds `SparkMonthName` to `datafusion-spark`'s datetime functions. It
uses `arrow::compute::date_part(DatePart::Month)` to extract the month
number and maps it to the abbreviated name. The signature accepts
**Timestamp types** with automatic coercion from Date32/Date64.

**Are these changes tested?**

Yes — 6 unit tests covering scalar dates, array dates with nulls, null
scalars, timestamp microseconds, all 12 months, and return field
nullability.

**Are there any user-facing changes?**

New `monthname` scalar function available when using `datafusion-spark`.

Subject: [PATCH 040/878] Guard to_timestamp decimal overflow (#22307)

## Which issue does this PR close?

- Closes #22213

## Rationale for this change

`to_timestamp` converted Decimal128 inputs to nanoseconds with unchecked
`i128` multiplication followed by an `as i64` cast. Large Decimal128
values could overflow during nanosecond scaling, causing a panic in
debug builds or a wrapped timestamp value in release builds.

## What changes are included in this PR?

- Convert Decimal128-to-nanoseconds scaling to checked arithmetic.
- Return a DataFusion error when the scaled value cannot fit in
timestamp nanoseconds.
- Cover both scalar and array Decimal128 overflow paths.
- Add a sqllogictest regression for the reported query shape.

## Are these changes tested?

- `cargo fmt --check`
- `git diff --check`

Subject: [PATCH 042/878] Port LikeExpr to use try_to_proto / try_from_proto
 (#22471)

## Which issue does this PR close?

  - Closes #22431.

  ## Rationale for this change

`LikeExpr` still serialized through the central physical proto
conversion chain. This change moves serialization and deserialization
responsibility into the expression
type itself, following the established migration pattern used for
`Column` and `BinaryExpr`.

  ## What changes are included in this PR?

  - Add `LikeExpr::try_to_proto`
  - Add `LikeExpr::try_from_proto`
  - Route physical proto decode through `LikeExpr::try_from_proto`
  - Remove the central `LikeExpr` encode and decode branches
  - Keep behavior and wire shape unchanged
- Rely on existing physical proto roundtrip coverage instead of an extra
expression-local roundtrip test

  ## Are these changes tested?

  Yes.

  Existing physical proto roundtrip coverage already covers `LikeExpr`.

  Verification run:
  - `cargo fmt --all`
  - `cargo test -p datafusion-physical-expr --features proto`
  - `cargo check -p datafusion-proto --all-features`
- `cargo clippy -p datafusion-physical-expr -p datafusion-proto
--all-targets --all-features -- -D warnings`

  ## Are there any user-facing changes?

  No.

Subject: [PATCH 044/878] feat(physical-expr): DynamicFilterTracker for cheap
 dynamic-filter change detection (#22460)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extracted from a design discussion around the duplicated "does this
filter have a dynamic portion that might change?" / "has the filter
changed?" patterns (e.g. #22450, `FilePruner`).

## Rationale for this change

`DynamicFilterPhysicalExpr` has a rich *producer* API (`update()`,
`mark_complete()`, `wait_update()`, `wait_complete()`), but *consumers*
that hold a predicate which *contains* dynamic filters only had a bare,
recursive `snapshot_generation() -> u64`. Call sites hand-rolled the
same boilerplate around it: store a `last_generation`, recompute
`snapshot_generation(&predicate)` (a full tree walk) on **every** check,
diff it, and rebuild an expensive `PruningPredicate` on change.
`FilePruner` did exactly this, and none of these consumers exploited
`mark_complete()`.

This adds a small consumer-side counterpart so the pattern lives in one
place, driven by the existing `watch` channel rather than by re-walking
the tree.

This immediately eliminates some tree traversals (we were constantly
traversing the expression tree to check if any filters updated). Long
term I hope this makes changes like #22450 easier.

## What changes are included in this PR?

**New public API (`datafusion_physical_expr`):**
- `DynamicFilterTracking` (`classify` → `Static` / `AllComplete` /
`Watching`, plus `contains_dynamic_filter` / `watcher`) and
`DynamicFilterTracker` (`changed`). A tracker walks a (possibly
composite) predicate **once**, subscribes to every still-incomplete
dynamic filter, and answers `changed()` by polling only that shrinking
set — steady-state is one atomic load per filter, no tree walk, no lock
until something actually moves.
- Lives in the `expressions::dynamic_filters` module
(`dynamic_filters.rs` → `dynamic_filters/mod.rs`, tracker in
`dynamic_filters/tracker.rs`). The subscription plumbing (`subscribe`,
`DynamicFilterSubscription`, `DynamicFilterChange`, `observe`,
`is_complete`) is `pub(crate)`; test-only constructors are
`#[cfg(test)]`.

**Consumers:**
- `FilePruner` is driven by `DynamicFilterTracking` instead of
`snapshot_generation` polling, and now decides its own existence in
`try_new` (a static predicate with no usable stats builds no pruner).
- The Parquet opener skips wrapping the scan in `EarlyStoppingStream`
when nothing can change, and no longer needs an "is it dynamic?" gate.

## Are these changes tested?

Yes — unit tests for the tracker (classification, detect-update-once,
`mark_complete` is not a change, coalesced update+complete,
multi-filter), plus the existing `datafusion-pruning` /
`datafusion-datasource-parquet` suites (incl. the
static/dynamic/partition opener pruning test) pass unchanged.

## Are there any user-facing changes?

New public API as above (additive). One **deprecation** and one behavior
change, both documented in the [DataFusion 55.0.0 upgrade
guide](docs/source/library-user-guide/upgrading/55.0.0.md):

-
`datafusion_physical_expr_common::physical_expr::is_dynamic_physical_expr`
is **deprecated (since 55.0.0)** — downcast to
`DynamicFilterPhysicalExpr` or use `DynamicFilterTracking`.
(`snapshot_generation` itself is unchanged — still backing the FFI
vtable and proto roundtrip.)
- `FilePruner::try_new` now returns `None` for a purely static predicate
over a file with no usable column statistics (previously `Some` whenever
a statistics struct was present).

## Followups

I noticed a possible follow-up gate refinement, tracked in #22495.

This also opens up the possibility to deprecate / remove the `snapshot`
/ `generation` machinery from the public physical expr APIs. These new
APIs (the watchers, tracker) subsumes much of the functionality, and I
don't think we want to add `PhysicalExpr::watch`. And after several
releases the only thing using it right now is dynamic filters, i.e. no
other legitimate use case has materialized.

+//! Tracking changes to the dynamic filters inside a predicate.
+//!
+//! Several operators (Parquet file/row-group pruning, remote execution, ...)
+//! hold a predicate that *may* contain one or more
+//! [`DynamicFilterPhysicalExpr`] nodes which are updated during execution
+//! (e.g. a `TopK` tightening its threshold, or a `HashJoinExec` publishing the
+//! build-side bounds). These consumers repeatedly ask two questions:
+//!
+//! 1. *"Does this predicate contain anything that can still change?"* — to
+//!    decide whether it is worth setting up runtime re-pruning at all.
+//! 2. *"Has it changed since I last looked?"* — to decide whether to rebuild an
+//!    expensive derived artifact (e.g. a `PruningPredicate`).
+//!
+//! Historically each call site answered these by recursively folding
+//! [`PhysicalExpr::snapshot_generation`] over the whole tree on *every* check
+//! and diffing the resulting `u64`. [`DynamicFilterTracker`] replaces that with
+//! a single up-front walk that subscribes to each still-incomplete dynamic
+//! filter; subsequent checks only poll the (shrinking) set of subscriptions,
+//! each of which is a cheap atomic load in the common "nothing changed" case.

+## DataFusion 55.0.0
+
+**Note:** DataFusion `55.0.0` has not been released yet. The information provided
+in this section pertains to features and changes that have already been merged
+to the main branch and are awaiting release in this version.
+
+### `is_dynamic_physical_expr` is deprecated
+
+`datafusion_physical_expr_common::physical_expr::is_dynamic_physical_expr` is
+deprecated. It was a thin wrapper over `snapshot_generation(expr) != 0` used to
+ask "does this predicate contain a dynamic filter?".
+
+Prefer asking the question directly against the concrete type. For a one-off
+check, downcast to `DynamicFilterPhysicalExpr`:
+
+```rust
+use datafusion_physical_expr::expressions::DynamicFilterPhysicalExpr;
+use datafusion_common::tree_node::{TreeNode, TreeNodeRecursion};
+
+let mut is_dynamic = false;
+predicate.apply(|e| {
+    if e.downcast_ref::<DynamicFilterPhysicalExpr>().is_some() {
+        is_dynamic = true;
+        Ok(TreeNodeRecursion::Stop)
+    } else {
+        Ok(TreeNodeRecursion::Continue)
+    }
+})?;
+```
+
+If you also need to know whether the dynamic filters can still change (and to be
+notified when they do), use the new `DynamicFilterTracking` /
+`DynamicFilterTracker` API in `datafusion_physical_expr`:
+
+```rust
+use datafusion_physical_expr::DynamicFilterTracking;
+
+let tracking = DynamicFilterTracking::classify(&predicate);
+if tracking.contains_dynamic_filter() {
+    // worth re-evaluating the predicate at runtime
+}
+```
+
+### `FilePruner::try_new` no longer builds a pruner for static predicates without statistics
+
+`datafusion_pruning::FilePruner::try_new` now returns `None` when the predicate
+is purely static _and_ the file carries no usable column statistics, because
+such a pruner can never prune anything beyond what planning already did.
+Previously it returned `Some` whenever a statistics struct was present (the
+"is this worth pruning?" decision lived in the Parquet opener). Files with column
+statistics, and predicates that carry a dynamic filter, are unaffected.

Subject: [PATCH 045/878] refactor: port InListExpr to use
 try_to_proto/try_from_proto hooks (#22503)

## Which issue does this PR close?

- Closes #22425

## Rationale for this change

This PR migrates InListExpr to use the new try_to_proto and
try_from_proto hooks, following the modular serialization architecture
established in #21835 . This moves serialization logic into the
expression itself, improving encapsulation and decentralizing the
datafusion-proto logic as part of the broader effort in #22418

## What changes are included in this PR?

 - Implemented `PhysicalExpr::try_to_proto for InListExpr`.
 - Implemented `InListExpr::try_from_proto` inherent method.
- Wired hooks in `from_proto.rs` and removed the central downcast arm in
to_proto.rs.
- Added isolated unit tests in `in_list.rs` using mock drivers to verify
roundtrips and error handling.


## Are these changes tested?

Yes, these changes are covered by both new and existing tests:

- New Unit Tests: Added mod `proto_tests` to in_list.rs using mock
drivers to verify `try_to_proto` and `try_from_proto` in isolation.
These cover successful roundtrips, incorrect node types, and missing
required fields.
- Existing Integration Tests: Verified that the existing InList
roundtrip tests in datafusion-proto continue to pass after removing the
central downcast logic.
- Linting: Verified that the changes pass cargo `clippy --all-targets
--all-features` with zero warnings.

## Are there any user-facing changes?

No.

Subject: [PATCH 046/878] refactor(physical-expr): add proto ctx expr helpers
 and adopt in InList/Like (#22513)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #22418 (decentralizing `datafusion-proto` serialization onto
the expressions themselves; follows #21835, #22471, #22503).

## Rationale for this change

Expressions migrating to the `try_to_proto` / `try_from_proto` hooks
keep hand-rolling the same boilerplate that the central
`datafusion-proto` match already factors out via `parse_physical_exprs`,
`parse_required_physical_expr`, and `serialize_physical_exprs`. Those
free functions can't be reused by expression authors: they take
`PhysicalProtoConverterExtension` / `PhysicalPlanDecodeContext`, which
the `PhysicalExprEncodeCtx` / `PhysicalExprDecodeCtx` surfaces
deliberately hide.

This was raised in review on #22503 — rather than re-implement the list
maps and "missing required field" checks in every migrated expression,
expose the same shapes on the ctx structs.

## What changes are included in this PR?

- **`datafusion-physical-expr-common`**: three thin convenience methods,
built on the existing `encode_child` / `decode` primitives:
  - `PhysicalExprEncodeCtx::encode_children_expressions`
- `PhysicalExprDecodeCtx::decode_required_expression` (also standardizes
the `Missing required field "<name>"` error so each expression no longer
spells its own)
  - `PhysicalExprDecodeCtx::decode_children_expressions`
- **`datafusion-physical-expr`**: adopt them in `InListExpr` and
`LikeExpr`, removing the hand-rolled list maps and per-field
`ok_or_else` checks.

### Behavior note

`decode_required_expression` couples the presence check with the decode,
so `LikeExpr` now decodes children left-to-right rather than validating
both required fields up front. The end result is unchanged (a missing
required field still errors), but a present sibling is decoded before a
later missing field is reported. The
`try_from_proto_rejects_missing_pattern` unit test is updated to reflect
this.

## Are these changes tested?

Yes — covered by existing tests, no new ones needed:

- The isolated `proto_tests` modules in `in_list.rs` and `like.rs`
already exercise all three helpers (list encode/decode, required decode,
and the missing-field + child-error paths) through the migrated
`try_to_proto` / `try_from_proto`.
- The `datafusion-proto` round-trip integration tests
(`roundtrip_inlist`, `roundtrip_like`,
`roundtrip_filter_with_not_and_in_list`,
`test_tpch_part_in_list_query_with_real_parquet_data`, etc.) continue to
pass.
- `cargo clippy --all-targets --features proto -D warnings` is clean on
the touched crates; `cargo fmt --all` applied.

## Are there any user-facing changes?

No. The per-expression `missing required field` error wording is
preserved: `LikeExpr` is byte-for-byte identical, and `InList` only
changes its label from `InList` to `InListExpr` (the actual type name).
The format now lives in one place (`decode_required_expression`) instead
of being hand-spelled per expression.

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Similar to #22387 (array_replace scalar optimization)

`array_remove` / `array_remove_n` / `array_remove_all` perform
element-wise comparison by invoking `compare_element_to_list` against
each row's sub-array individually. When the needle is a scalar, this can
be optimized by performing a single vectorized `distinct` comparison
over the entire flattened values buffer.


## What changes are included in this PR?


- Add a specialized removal kernel (`general_remove_with_scalar`) that
uses `arrow_ord::cmp::distinct` with `Scalar` wrapper for a single bulk
comparison pass over the flat values buffer.
- Extend SLT tests with multi-row scalar-argument coverage,
NULL-containing arrays, empty-array edge cases, boundary `n` values, and
LargeList type coverage.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes, existing and new SLT edge-case tests in `array_remove.slt`.

## Are there any user-facing changes?

No.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

From 7c39318b8f372396e73e99aaed92667b2dfe3fd3 Mon Sep 17 00:00:00 2001
From: Neil Conway <neil.conway@gmail.com>

Subject: [PATCH 048/878] feat: Improve display of `Decimal` values (#22500)

## Which issue does this PR close?

- Closes #22485.

## Rationale for this change

Displaying `Decimal` values (e.g., in `EXPLAIN` output or in
auto-generated column names) included Rust's `Some` notation. For
example:

```
> set datafusion.sql_parser.parse_float_as_decimal = true; explain select 0.1;
```

Eliding the rest of the `EXPLAIN` output, the projection is rendered as
as `Decimal128(Some(1),1,1): Some(1),1,1`.

This is not very readable:
1. Users may not understand the Rust `Option` syntax
2. When the value is `None`, we should print `NULL`, so showing the
`Option` is not useful anyway
3. The user needs to do math to convert the stored value (`1`) into the
actual value (`0.1`)

This PR changes how `Decimal` values are displayed. For example, the
query above would show the projection as: `Decimal128(0.1,1,1): 0.1`.

## What changes are included in this PR?

* Update `fmt::Display` and `fmt::Debug` for `ScalarValue` to use the
new format for `Decimal` values
* Rename `fmt_binary` to `fmt_binary_debug` for consistency (this format
is used by `Debug`, not `Display`)
* Add unit tests for new formatting behavior
* Update SLTs / goldens for new output format
* Update migration guide for new output format

## Are these changes tested?

Yes; new tests added and expected test output has been updated. The
implemented behavior was compared with Postgres and DuckDB, and roughly
matches what those other systems do.

## Are there any user-facing changes?

Yes. This change may break users that have `EXPLAIN` output or
auto-generated column names in golden files, and other places where the
`Debug` / `Display` of a `ScalarValue` is being compared against. A
section has been added to the 55.0.0 migration guide.

+### Decimal scalar formatting uses human-readable values
+
+Decimal scalar literals in `EXPLAIN` output, expression display strings, and
+auto-generated column names now format the decimal value using its scale while
+still showing the precision and scale. For example, a `Decimal128` literal with
+stored value `1`, precision `1`, and scale `1` is now rendered as
+`Decimal128(0.1,1,1)` instead of `Decimal128(Some(1),1,1)`. When formatting a
+`ScalarValue` directly, it now appears as `0.1` instead of `Some(1),1,1`.
+
+`NULL` decimal literals were previously shown as `Decimal128(None,10,2)`; they
+will now appear as `Decimal128(NULL,10,2)`.
+
+Query result values already used human-readable decimal formatting and are
+unchanged.

Subject: [PATCH 049/878] feat(catalog): expose InformationSchemataBuilder as
 public API (#22499)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

No linked issue. Happy to file one if reviewers prefer.


## Rationale for this change

Downstream catalog implementations that resolve schemas asynchronously
cannot reuse `InformationSchemaProvider` — it enumerates schemas via
`CatalogProvider::schema_names()`, which is synchronous, so an
async-only catalog has to provide its own `information_schema.schemata`
view. Today that requires either duplicating the column layout and
the row-building logic, or reaching into private items.

Exposing `InformationSchemataBuilder` and a `schemata_schema()` factory
lets external crates emit byte-for-byte-compatible `schemata` batches
without copy-pasting the contract.

## What changes are included in this PR?

- `pub fn schemata_schema() -> SchemaRef` — extracts the column-layout
  factory. `InformationSchemata::new` now calls it instead of inlining
  the schema, so there is a single source of truth.
- `InformationSchemataBuilder` becomes `pub` (was private) with a
  `Default` impl and a public `new()`. `add_schemata` and `finish` are
  bumped to `pub`. The function bodies and parameter types
  (`&str` / `Option<&str>`) are unchanged.
- `finish` now returns `Result<RecordBatch>` instead of panicking via
  an internal `.unwrap()`. The one internal caller
  (`PartitionStream::execute` for `InformationSchemata`) was previously
  wrapping `Ok(builder.finish())` and is updated to just
  `builder.finish()` since the inner expression now produces the
  `Result` directly.

## Are these changes tested?

Yes. A new unit test `schemata_builder_emits_canonical_schema_and_rows`
exercises the public API end-to-end via `Default::default()`, asserts
the produced batch's schema matches `schemata_schema()`, and verifies
the null pattern for `schema_owner`, the three `default_character_set_*`
columns, and `sql_path`. The pre-existing internal users
(`InformationSchemata::new`, `PartitionStream::execute`) continue to
exercise the same code path through the unchanged
`InformationSchemata::builder()` constructor.

## Are there any user-facing changes?

Yes — three new public items in `datafusion-catalog`: `schemata_schema`,
`InformationSchemataBuilder` (with its `new` / `add_schemata` / `finish`
methods + `Default` impl). No existing public API is broken. The
`Result<RecordBatch>` return on `finish` is a first-time-public surface,
not a regression.

Subject: [PATCH 050/878] fix: avoid panic in date_bin compute_distance near
 i64::MIN (#22408)

## Which issue does this PR close?

- Closes #22215.

## Rationale for this change

`date_bin` panics with `attempt to subtract with overflow` when the
source timestamp sits near `i64::MIN` because `compute_distance` does
`time_diff - (time_diff % stride)` and then `time_delta - stride` on raw
`i64`. The scalar pipeline already maps `Err` from `bin_fn` into `NULL`,
so the fix is to surface the overflow as a normal error.

## What changes are included in this PR?

- Convert `compute_distance` to return `Result<i64>` and use
`checked_sub`.
- Propagate the result through `date_bin_nanos_interval` and
`date_bin_months_interval`, plus replace the trailing `origin +
time_delta` with `checked_add`.

## Are these changes tested?

Yes. Added `test_date_bin_compute_distance_i64_min` which previously
panicked and now returns `NULL`. Ran `cargo test -p datafusion-functions
--lib -- datetime::date_bin`, `cargo fmt --check`, and `cargo clippy -p
datafusion-functions --lib --tests --no-deps`.

## Are there any user-facing changes?

Queries that previously panicked on extreme timestamps now return `NULL`
(consistent with the existing out-of-range behavior covered by
`test_date_bin_out_of_range`).

Subject: [PATCH 052/878] feat: add array_scale scalar function (#22466)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Partial of #21536 — `array_scale` (the list+scalar arithmetic function
in the vector math series).

## Rationale for this change

Continues the per-function split requested by @alamb on #21536. Three
sibling PRs already merged: `cosine_distance` (#21542), `inner_product`
(#21861), `array_normalize` (#22013). `array_add` is in flight as #22459
by @SubhamSinghal.

Adds element-wise scalar multiplication for numeric arrays, returning a
list of the same shape. Aliased as `list_scale` to match the `array_X` /
`list_X` precedent in this crate.

## What changes are included in this PR?

- New scalar UDF `array_scale(array, scalar)` in
`datafusion/functions-nested/src/array_scale.rs`
- Module wire-up + registration in
`datafusion/functions-nested/src/lib.rs`
- SLT tests at `datafusion/sqllogictest/test_files/array_scale.slt`
- Auto-generated function docs entry in
`docs/source/user-guide/sql/scalar_functions.md`

**Signature:** first arg `List/LargeList/FixedSizeList<numeric>`, second
arg numeric scalar. Both coerce to `Float64`. Same list-widening rules
as the binary-op siblings.

**NULL semantics:**
- NULL row in array → NULL row out
- NULL scalar → NULL row out (whole-row, because the scalar applies
uniformly)
- NULL element at position \`i\` → NULL element at \`i\` out
(per-element propagation)
- Empty array → empty array

**Builders:** uses \`OffsetBufferBuilder\` + \`NullBufferBuilder\` per
the pattern adopted in the round-1 review of #22013.

## Are these changes tested?

Yes. \`array_scale.slt\` covers:
- Happy paths (positive, negative, zero, fractional, single-element)
- NULL propagation at all three levels (NULL row, NULL scalar, NULL
element)
- All list type variants (\`List\`, \`LargeList\`, \`FixedSizeList\`)
- Numeric inner type coercion (Float32, Int64, integer literals)
- Multi-row queries with both constant-scalar broadcast and per-row
column scalar
- Error paths (non-numeric scalar, non-list first arg, wrong arity)
- Empty array
- \`list_scale\` alias

## Are there any user-facing changes?

Yes — new SQL scalar function \`array_scale(array, scalar)\` and its
alias \`list_scale\`. Documented in
\`docs/source/user-guide/sql/scalar_functions.md\`.

Subject: [PATCH 053/878] fix: make array null argument handling follow SQL
 semantics (#22508)

## Which issue does this PR close?

  - Closes #22507.

  ## Rationale for this change

Some array functions were not handling null index or count arguments
correctly.

A null `size` or `max` value was sometimes treated like `0`, which gave
wrong results like `[]` or the original array. `array_element` also
depended on Arrow buffer values in null slots.

  This change makes these functions follow normal SQL null rules.

  ## What changes are included in this PR?

  - Make `array_resize` return `NULL` when `size` is `NULL`
  - Make `array_replace_n` return `NULL` when `max` is `NULL`
  - Make `array_remove_n` return `NULL` when `max` is `NULL`
  - Make `array_element` check for null indexes explicitly
- Clean up `array_repeat` so null counts stay explicit in offset
building
- Update `array_remove_n` field nullability so planner metadata matches
runtime behavior
  - Add regression tests for these cases
  - Update SQL logic test outputs for the changed null behavior

  ## Are these changes tested?

  Yes.

I added regression tests for the changed Rust paths and updated the SQL
logic tests.


  ## Are there any user-facing changes?

These functions now return `NULL` for null index or count arguments
instead of returning `[]`, an unchanged array, or relying on accidental
behavior.

Subject: [PATCH 054/878] refactor: add `try_to_proto` to `HashTableLookupExpr`
 (#22451)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?
Part of #22435

## What changes are included?
Adds `try_to_proto` to `HashTableLookupExpr` so it participates in the
expression-local serialization pattern introduced in #21929.

`HashTableLookupExpr` holds a runtime `Arc<Map>` that cannot be
serialized, so `try_to_proto` replaces it with `lit(true)`. This is
safe because the filter is a performance optimisation only — `lit(true)`
passes all rows and the join produces correct results either way.

The centralized arm in `to_proto.rs` remains as a fallback for now.
Cleanup can follow in a separate PR once this lands.

## Are these changes tested?
Yes — covered by the existing `roundtrip_hash_table_lookup_expr_to_lit`
test in `datafusion/proto/tests/cases/roundtrip_physical_plan.rs`.

## Are there any user-facing changes?
No.

Subject: [PATCH 055/878] perf: Optimize `split_part` using bulk-NULL string
 builders (#22283)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22282.

## Rationale for this change

`split_part` currently uses the Arrow StringBuilder types and computes
NULLs on a per-row basis. This PR switches to using the new bulk-NULL
string builders.

Benchmarks (Arm64):

  - scalar_utf8_single_char / pos_first: 44.6 µs → 39.1 µs (−11.2%)
  - scalar_utf8_single_char / pos_middle: 102.6 µs → 95.8 µs (−6.4%)
  - scalar_utf8_single_char / pos_negative: 48.6 µs → 42.5 µs (−12.4%)
  - scalar_utf8_multi_char / pos_middle: 134.1 µs → 130.4 µs (−2.9%)
- scalar_utf8_long_strings / pos_middle: 1089 µs → 1101 µs (+1.3%,
within noise)
- scalar_utf8view_long_parts / pos_middle: 140.6 µs → 138.0 µs (−2.0%,
within noise)
- scalar_utf8view_very_long_parts / pos_first: 68.9 µs → 69.4 µs (+1.3%,
within noise)
  - array_utf8_single_char / pos_middle: 360.2 µs → 346.6 µs (−3.9%)
- array_utf8_multi_char / pos_middle: 354.3 µs → 343.2 µs (−2.2%,
borderline)

## What changes are included in this PR?

* Switch to new string builder types; compute NULLs in bulk via
`NullBuffer::union_many`

## Are these changes tested?

Yes, covered by existing tests.

## Are there any user-facing changes?

No.

Subject: [PATCH 056/878] Simplify get_field over inline struct constructors
 (#22239)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

https://github.com/apache/datafusion/issues/22240

## Rationale for this change

Constructing a struct with `named_struct(...)` (or `struct(...)`) and
then immediately reading a field back out of it is pure overhead — the
intermediate struct never needs to be materialized. This pattern shows
up after view/CTE inlining and projection pushdown, where a
`named_struct` projection feeds a `get_field` in a parent node.

For example:

```sql
CREATE VIEW t AS (
  SELECT named_struct('type', type, 'value', value) as s
);

SELECT get_field(s, 'value') FROM t;
```

`get_field(named_struct('type', type, 'value', value), 'type')` is
equivalent to `type`, so the simplifier can drop the struct entirely.
This is especially important because without this simplification no
statistics pruning can be applied.

## What changes are included in this PR?

A new logical simplification, added to `GetFieldFunc::simplify` (the
same hook that already flattens nested `get_field` calls):

- `get_field(named_struct('min', a, 'max', b), 'max')` => `b` (lookup by
name)
- `get_field(struct(a, b), 'c1')` => `b` (positional `c0`, `c1`, ...
fields)
- nested constructors collapse all the way through, e.g.
`named_struct('outer', named_struct('inner', a))['outer']['inner']` =>
`a`

The rewrite is conservative and bails out (leaving the expression
untouched) whenever it cannot be proven safe:

- a non-literal field key,
- a `named_struct` with a non-literal field name (which could shadow the
requested field at runtime),
- a field the constructor does not produce,
- non-canonical `struct` field spellings such as `c01`.

Casts are intentionally **not** unwrapped: a struct→struct cast can
rename, retype and reorder fields, so resolving through one correctly is
a larger, separate change.

## Are these changes tested?

Yes:

- Unit tests in `getfield.rs` covering matches, duplicate names, nested
constructors, flatten-then-resolve, and every bail-out guard.
- `struct.slt`: query + `EXPLAIN` tests showing the field access
collapses to the underlying column.
- `order.slt`: two `EXPLAIN` expectations updated — resolving
`get_field(named_struct(...), 'a')` lets the `extract_leaf_expressions`
rule skip a now-pointless sort-key extraction. The `SortExec` is still
present, as those tests intend, and the sort-elimination cases are
unchanged.

The full `sqllogictest` suite, the optimizer crate tests, `cargo clippy
--all-targets --all-features -D warnings` and `cargo fmt` all pass.

## Are there any user-facing changes?

No API changes. Query plans involving `get_field` over an inline struct
constructor are simpler; results are unchanged.

Subject: [PATCH 057/878] Add regression coverage for DATE interval overflow
 (#22519)

## Summary

- add sqllogictest coverage for DATE + INTERVAL day overflow near the
Date32 boundary
- assert the issue repro returns the existing `Date arithmetic overflow`
error instead of panicking

Closes #22233.

## Notes

Current upstream `main` already returns the expected overflow error for
this repro, so this PR is regression coverage only.

## Tests

- `cargo test -p datafusion-expr-common test_overflow_handling --
--nocapture`
- `cargo test --profile=ci --test sqllogictests --
datetime/arith_date_interval.slt`

Subject: [PATCH 058/878] feat: adds array_add function (#22459)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of [#21536](https://github.com/apache/datafusion/issues/21536)
(array_add — first PR in the vector math series).

  ## Rationale for this change

  ## What changes are included in this PR?

  ## Are these changes tested?

  Yes, via SLT only (`array_add.slt`). Coverage:
- Happy paths: basic, negative components, single-element, empty,
multi-row.
- NULL propagation: whole-row NULL on each side / both sides;
element-level NULL on each side / both sides at same
  and different positions.
- Type / variant: integer literals, mixed int+float,
`LargeList`×`LargeList`, mixed `List`+`LargeList`,
  `FixedSizeList` → `List` coercion, `Float32` leaf, `Int64` leaf.
- Decimal handling: `Decimal128` / `Decimal256` rejected at planning;
explicit `cast to DOUBLE` opt-in works.
- Error paths: per-row length mismatch (exec), unsupported non-list
input (plan), non-numeric leaf (plan), boolean
  leaf (plan), nested list (plan), wrong arg count.
  - Aliases: `list_add` single-row + multi-row.
- Composition: `array_add(array_add(...), ...)` chained — single-row,
with element NULLs propagating across both
  layers, and multi-row with row-level NULL.

  ## Are there any user-facing changes?

  Yes — two new functions:
  - `array_add(array1, array2) → List<Float64>` / `LargeList<Float64>`
  - `list_add(...)` alias

Both exposed via `expr_fn` and registered in
`all_default_nested_functions()`. Documented inline via `#[user_doc]`
  (description, syntax, SQL example, argument descriptions).

  No breaking API changes.

+### `array_add`
+
+Returns the element-wise sum of two numeric arrays of equal length, computed as `array1[i] + array2[i]` per position. NULL is propagated per element: if either input element at position `i` is NULL, the corresponding output element is NULL (positions are preserved). Returns NULL if either entire input array is NULL. Errors if the per-row lengths differ. Returns an empty array if both inputs are empty.

Subject: [PATCH 059/878] Add minimal APIs / hooks for granular statistics
 collection in TableProvider implementations (#22300)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Related to #21996
- Related to #21624

This is **not** a replacement for #21996 — it is a minimal subset of it,
carved out so the feature can be discussed/merged in smaller pieces.

## Rationale for this change

#21996 ("Query-aware statistics requests via ScanArgs / ScanResult") is
a full vertical slice: new statistics types, request threading optimizer
→ planner → provider, a built-in `RequestStatistics` optimizer rule, and
a consumer integration (`FilePruner` / `ListingTable`).

This PR extracts **only the framework hooks** — just enough that the
rest can be implemented *entirely outside* of DataFusion. A third party
can write their own optimizer rule to derive statistics requests, and
their own `TableProvider` to consume them, without DataFusion shipping
any rule or consumer of its own.

In stock DataFusion nothing observable changes: no rule populates the
new field, and the built-in providers ignore it.

## What changes are included in this PR?

Five small, independently-reviewable commits:

1. **`refactor: add TableScanBuilder, deprecate TableScan::try_new`** —
`TableScan::try_new` takes five positional args and bare `TableScan { ..
}` literals are fragile to field additions. Introduce `TableScanBuilder`
(with `From<TableScan>`), move schema derivation into `build()`,
deprecate `try_new` (delegates to the builder), migrate all in-tree
callers. Pure refactor.
2. **`feat: add StatisticsRequest type`** — a new public
`StatisticsRequest` enum in `datafusion-expr-common::statistics`
(Min/Max/NullCount/DistinctCount/Sum/ByteSize per column, plus
RowCount/TotalByteSize). Nothing consumes it yet.
3. **`feat: add TableScan::statistics_requests field`** — an advisory
`BTreeSet<StatisticsRequest>` on `TableScan`. A **set** so
request-deriving optimizer rules stay idempotent under fixpoint
iteration (a rule `insert`s its requests; re-running is a no-op and
composes with other rules — no per-rule dedup). Empty by default;
DataFusion's own rules never populate it.
4. **`feat: thread statistics requests into ScanArgs`** — `ScanArgs`
gains `statistics_requests`; the physical planner threads
`TableScan::statistics_requests` into it so the request reaches
`TableProvider::scan_with_args`.
5. **`test: e2e statistics-request flow via a custom optimizer rule`** —
an integration test playing both external roles.

Deliberately **left out** vs #21996, since this PR is request-side only:
the built-in `RequestStatistics` optimizer rule, the `FilePruner` /
`ListingTable` consumer integration, the
`PartitionedFile::satisfied_stats` per-file response field, and the
response-side types (`StatisticsValue` / `SatisfiedStatistics`). Those
belong with whatever actually wires the response side.

## Are these changes tested?

Yes:
- `datafusion/core/tests/user_defined/statistics_requests.rs`: an
end-to-end integration test where a custom `OptimizerRule` annotates
`TableScan` and a custom `TableProvider` asserts the requests reach
`scan_with_args` — plus a test that without such a rule the provider
sees an empty request list.
- All existing `datafusion-expr` / `datafusion-optimizer` /
`datafusion-proto` tests pass against the `TableScanBuilder` refactor.

## Are there any user-facing changes?

Yes — this needs the `api change` label:

- New public type `StatisticsRequest` (re-exported via
`datafusion_expr::statistics`).
- New `TableScanBuilder`; `TableScan::try_new` is **deprecated** (still
works, delegates to the builder).
- `TableScan` gains a new public field `statistics_requests` — this
breaks exhaustive `TableScan { .. }` struct literals downstream (the
recommended fix is `TableScanBuilder`).
- `ScanArgs` gains `with_statistics_requests` / `statistics_requests`.

Subject: [PATCH 061/878] Make DiskManager max_temp_directory_size dynamically
 adjustable (#22246)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change `max_temp_directory_size` from `u64` to `AtomicU64` so the spill
disk limit can be adjusted at runtime without requiring exclusive
(`&mut`) access to the DiskManager.

Before this change, `set_max_temp_directory_size` required `&mut self`
which was unavailable after the DiskManager was shared via `Arc` (as it
always is in production through RuntimeEnv). The only workaround was
`set_arc_max_temp_directory_size` which required `Arc::get_mut` — always
failing when multiple sessions held references.

After this change, `set_max_temp_directory_size` takes `&self` and uses
an atomic store. Any thread can adjust the limit, and subsequent spill
writes immediately see the new value.

Use cases:
- Adaptive spill limits based on available disk space
- Runtime cluster setting changes without restart
- Graceful degradation under disk pressure

The `set_arc_max_temp_directory_size` method is deprecated but kept for
backward compatibility — it now delegates to the `&self` method.

Performance: `AtomicU64::load(Acquire)` adds ~1ns per spill write check.
Negligible since spill writes take milliseconds.

<li><em>Breaking change</em>: Bump the minimum required CodeQL bundle
version to 2.19.4. <a
href="https://redirect.github.com/github/codeql-action/pull/3894">#3894</a></li>

<a

</ul>
<h2>4.35.5 - 15 May 2026</h2>
<ul>
<li>We have improved how the JavaScript bundles for the CodeQL Action
are generated to avoid duplication across bundles and reduce the size of
the repository by around 70%. This should have no effect on the runtime
behaviour of the CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3899">#3899</a></li>
<li>For performance and accuracy reasons, <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> will now only be enabled on a pull request when
diff-informed analysis is also enabled for that run. If diff-informed
analysis is unavailable (for example, because the PR diff ranges could
not be computed), the action will fall back to a full analysis. <a
href="https://redirect.github.com/github/codeql-action/pull/3791">#3791</a></li>
<li>If multiple inputs are provided for the GitHub-internal
<code>analysis-kinds</code> input, only <code>code-scanning</code> will
be enabled. The <code>analysis-kinds</code> input is experimental, for
GitHub-internal use only, and may change without notice at any time. <a
href="https://redirect.github.com/github/codeql-action/pull/3892">#3892</a></li>
<li>Added an experimental change which, when running a Code Scanning
analysis for a PR with <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> enabled, prefers CodeQL CLI versions that have
a cached overlay-base database for the configured languages. This speeds
up analysis for a repository when there is not yet a cached overlay-base
database for the latest CLI version. We expect to roll this change out
to everyone in May. <a
href="https://redirect.github.com/github/codeql-action/pull/3880">#3880</a></li>
</ul>
<h2>4.35.4 - 07 May 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.4">2.25.4</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3881">#3881</a></li>
</ul>
<h2>4.35.3 - 01 May 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.19.3 and earlier. These versions of
CodeQL were discontinued on 9 April 2026 alongside GitHub Enterprise
Server 3.15, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3837">#3837</a></li>
<li>Configurations for private registries that use Cloudsmith or GCP
OIDC are now accepted. <a
href="https://redirect.github.com/github/codeql-action/pull/3850">#3850</a></li>
<li>Best-effort connection tests for private registries now use
<code>GET</code> requests instead of <code>HEAD</code> for better
compatibility with various registry implementations. For NuGet feeds,
the test is now always performed against the service index. <a
href="https://redirect.github.com/github/codeql-action/pull/3853">#3853</a></li>
<li>Fixed a bug where two diagnostics produced within the same
millisecond could overwrite each other on disk, causing one of them to
be lost. <a
href="https://redirect.github.com/github/codeql-action/pull/3852">#3852</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.3">2.25.3</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3865">#3865</a></li>
</ul>
<h2>4.35.2 - 15 Apr 2026</h2>
<ul>
<li>The undocumented TRAP cache cleanup feature that could be enabled
using the <code>CODEQL_ACTION_CLEANUP_TRAP_CACHES</code> environment
variable is deprecated and will be removed in May 2026. If you are
affected by this, we recommend disabling TRAP caching by passing the
<code>trap-caching: false</code> input to the <code>init</code> Action.
<a
href="https://redirect.github.com/github/codeql-action/pull/3795">#3795</a></li>
<li>The Git version 2.36.0 requirement for improved incremental analysis
now only applies to repositories that contain submodules. <a
href="https://redirect.github.com/github/codeql-action/pull/3789">#3789</a></li>
<li>Python analysis on GHES no longer extracts the standard library,
relying instead on models of the standard library. This should result in
significantly faster extraction and analysis times, while the effect on
alerts should be minimal. <a
href="https://redirect.github.com/github/codeql-action/pull/3794">#3794</a></li>
<li>Fixed a bug in the validation of OIDC configurations for private
registries that was added in CodeQL Action 4.33.0 / 3.33.0. <a
href="https://redirect.github.com/github/codeql-action/pull/3807">#3807</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.2">2.25.2</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3823">#3823</a></li>
</ul>
<h2>4.35.1 - 27 Mar 2026</h2>
<ul>
<li>Fix incorrect minimum required Git version for <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a>: it should have been 2.36.0, not 2.11.0. <a

## What changes are included in this PR?

added tests and validation for data_type input

## Are these changes tested?

just tests

## Are there any user-facing changes?
not really

Subject: [PATCH 067/878] minor: add `Any` to `QueryPlanner` trait (#22241)

## Which issue does this PR close?

- does not close the issue.

## Rationale for this change

Working on #22151 it seams that `QueryPlanner` should extend `Any` in
order to be downcastad to actual implementation. The main reason behind
cast is to support runtime change of inner query planner.

## What changes are included in this PR?

- trait `QueryPlanner` extends `Any`

## Are these changes tested?

Using existing tests

## Are there any user-facing changes?

this would be backward incompatible change

Subject: [PATCH 068/878] feat: add TableSchemaBuilder and store partition
 columns as Fields (#22496)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- No separate issue. Follows up on #22372 (panic fix in
`TableSchema::with_table_partition_cols`) and the API discussion it
spawned, and is informed by #22026 (which adds a third column group,
virtual columns, to `TableSchema`).

## Rationale for this change

`TableSchema` has one required input (the file schema) and a growing set
of *optional* column groups: partition columns today, virtual columns in
#22026. The current API expresses this awkwardly:

- `new(file_schema, partition_cols)` privileges partition columns with a
positional slot while virtual columns only get a builder method — an
asymmetry that grows with every new column kind.
- `TableSchema` eagerly recomputes and caches the concatenated table
schema on *every* incremental setter call, so
`from_file_schema(s).with_table_partition_cols(p)` rebuilds it twice
(three times once virtual columns are added). This is exactly why
`new()`'s docs told callers to avoid the builder-style chain.
- The setter mutated an inner `Arc<Vec<FieldRef>>` in place, which is
what caused the shared-`Arc` panic fixed in #22372.

A dedicated builder addresses all three, and mirrors the existing
`FileScanConfigBuilder` (the type that *owns* a `TableSchema`).

## What changes are included in this PR?

- **`TableSchemaBuilder`**: `new(file_schema)` →
`.with_table_partition_cols(impl Into<Fields>)` → `.build()`. The
concatenated table schema is computed exactly **once**, in `build()`.
The setter takes `impl Into<Fields>`, so an existing schema's `Fields`
is accepted zero-copy.
- **Partition columns are now stored as `arrow::datatypes::Fields`** (an
immutable `Arc<[FieldRef]>`) instead of `Arc<Vec<FieldRef>>`: one fewer
indirection, shareable zero-copy, and — being immutable — the
shared-`Arc` mutation panic is structurally impossible.
- **`TableSchema::table_partition_cols()` and the delegating
`FileScanConfig::table_partition_cols()` now return `&Fields`.**
`Fields` derefs to `&[FieldRef]`, so iteration/indexing/`len`/`is_empty`
are unchanged; only the arrow `FileFormat` path needed `.to_vec()`.
- **`TableSchema::with_table_partition_cols` is deprecated** in favor of
the builder. It now **replaces** rather than appends. (Note: `main`
currently *appends* here — the replace change in #22372 was not captured
by that PR's squash merge — so this also restores the intended replace
semantics.)
- `new` / `from_file_schema` are kept as conveniences that route through
the builder.
- Documented in the 54.0.0 upgrade guide.

This intentionally leaves virtual columns out; #22026 should extend the
builder with `with_virtual_columns` once it lands.

## Are these changes tested?

Yes. New unit tests cover building with partition columns,
replace-on-repeat, zero-copy `Fields` input, and the deprecated setter's
behavior; existing `TableSchema` / `FileScanConfig` tests and doctests
pass. `cargo clippy --all-targets -- -D warnings` is clean across the
datasource/proto/arrow/parquet/catalog-listing crates.

## Are there any user-facing changes?

Yes — please apply the `api change` label:

- `TableSchema::table_partition_cols()` /
`FileScanConfig::table_partition_cols()` return `&Fields` instead of
`&Vec<FieldRef>` (source-compatible for most uses via `Deref`).
- `TableSchema::with_table_partition_cols` is deprecated (use the
builder) and now replaces rather than appends.

## Summary

-
`datafusion/physical-plan/src/aggregates/group_values/multi_group_by/mod.rs:737`
- `scalarized_intern_remaining` doc said "preform" → "perform"
- `datafusion/core/tests/dataframe/mod.rs:843,895,943` - three
nearly-identical test comments said "functionally dependant" →
"functionally dependent"

Comment-only.

Subject: [PATCH 070/878] fix: Set Substrait output types for expressions
 (#20597)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #15831.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

The Substrait producer did not set the ScalarFunction `output_type` when
converting binary expressions, which broke consumers relying on the
`output_type`.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

* Refactor `from_join` and `from_between` to eliminate direct calls to
`make_binary_op_scalar_func`
* Set the Substrait ScalarFunction `output_type` when converting several
types of DataFusion expressions:
  * Binary expressions (`Expr::BinaryExpr`)
  * Unary expressions (like `Expr::Not`)
  * Scalar functions (`Expr::ScalarFunction`)

There are a few more places where the `output_type` has not been set,
such as `from_like` and `from_in_list`, as mentioned in #15831. I've
left these out of scope here as fixing them would require more
substantial code changes.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes, via a new unit test.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No, beyond the Substrait output fix.

From: "Zhen-Lun (Kevin) Hong" <kevink556@gmail.com>

Subject: [PATCH 071/878]  port `NegativeExpr` to use the `try_to_proto` /
 `try_from_proto` hooks (#22483)

## Which issue does this PR close?

- Closes #22426

## Rationale for this change

This change is part of the per-expression proto hooks migration #22418.
I moved the serialization and deserialization of `NegativeExpr` into its
proto hooks, keeping it aligned with the new pattern used by migrated
physical expressions and reducing special-case branching in the shared
conversion code.

## What changes are included in this PR?

- Added `try_to_proto` and `try_from_proto` to `NegativeExpr`
- Removed the central `NegativeExpr` serialization branch
- Updated `physical_plan/from_proto.rs` to route physical proto decode
through `try_from_proto`

## Are these changes tested?

Yes. This PR is verified by running

- `cargo fmt --all -- --check`
- `cargo check -p datafusion-physical-expr --features proto`
- `cargo check -p datafusion-proto`
- `cargo test -p datafusion-proto --test proto_integration
roundtrip_physical_plan`
- `cargo test -p datafusion-proto --test proto_integration
roundtrip_physical_expr`
- `git diff --check`

## Are there any user-facing changes?

No user-facing changes are intended.

Subject: [PATCH 072/878] fix: clear handled OFFSET before child recursion in
 LimitPushdown (#22525)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22489.

## Rationale for this change

`LimitPushdown` carries `GlobalRequirements` while walking the physical
plan.
In the bad plan shape from #22489, an outer `OFFSET` was already handled
above
a sort barrier, but its `skip` still remained in the state when
recursion
continued into the child subtree. That stale `skip` then merged with an
inner
`LIMIT` and reduced its fetch incorrectly, which caused a grouped row to
be
  dropped.

The fix is to clear `skip` once the limit requirement has already been
handled,
while keeping `fetch` so valid limit pushdown into child sorts still
happens.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

- Clear `skip` before recursing into children when the limit requirement
is already handled.
  - Keep `fetch` unchanged so valid TopK-style pushdown still works.
- Add a physical optimizer regression test for the exact outer `OFFSET`
/ sort barrier / inner `LIMIT` shape.
  - Add an end-to-end sqllogictest for the SQL reproducer from #22489.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No API Change

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 073/878] chore: update sqllogictest priority list with latest
 timing summary (8s --> 6s) (#22549)

## Which issue does this PR close?

- Follow-up to #20656.

## Rationale for this change

Make running sqllogictests faster by improving scheduling / parallelism

The sqllogictest runner runs test files in parallel but each file
sequentially, so it prioritizes known long-running files to run first to
minimize total wall-clock time. This list was last set in #20656.

The relative timings have since shifted. Running with the
`--timing-summary` flag now reports a different ordering of the longest
files, with `nested_loop_join_spill.slt` having become the longest by a

Subject: [PATCH 074/878] Add Physical `Partitioning::Range` enum variant
 (#22207)

## Which issue does this PR close?
- First mechanical PR for `ExprPartitioning` as described in thread:
#21992.

## Rationale for this change

DataFusion currently cannot truthfully represent range-partitioned
physical data. Some sources may be range partitioned, but have to
advertise another partitioning shape or fall back to unknown
partitioning.

This PR introduces the metadata shape for range partitioning without
implementing optimizer or execution behavior yet. The goal is to
establish the public representation first, then implement planning,
compatibility, and execution behavior incrementally in follow-up PRs.

## What changes are included in this PR?

- Adds `Partitioning::Range(RangePartitioning)`.
- Adds range metadata types:
  - `RangePartitioning`
  - `RangePartition`
  - `RangeInterval`
  - `RangeBound`
- Adds proto serialization/deserialization.
- Adds `not_impl_err!` handling for range partitioning at call sites.
- Preserves range partitioning through projection only when all
partition expressions can be projected, otherwise `UnknownPartitioning`.

## Are these changes tested?

Yes.

## Are there any user-facing changes?

Yes. This adds new public physical partitioning API and proto for range
partitioning.

Subject: [PATCH 075/878] perf: hoist split_vec_min_alloc to datafusion-common
 and shrink the emitted prefix (#22416)

## Which issue does this PR close?

Related to #22164 and #22165.

## Rationale for this change

#22165 added a `split_vec_min_alloc` helper so that `EmitTo::First(n)`
allocates `min(n, len - n)` instead of always copying `n` elements. This
PR finishes and corrects that work, following review:

- The helper was `pub(super)` inside `datafusion-physical-plan`, so it
could not be reused. It moves to `datafusion_common::utils` as the
single shared copy.
- The `split_off` branch returned the original allocation as the emitted
prefix: short length, but original (larger) capacity. datafusion
accounts memory by capacity rather than length, so that prefix did not
actually release memory under pressure. The helper now calls
`shrink_to_fit` on it.
- Two further `EmitTo::First(n)` paths still used the
`drain(..n).collect()` idiom: the min/max accumulators and
`ByteViewGroupValueBuilder::take_n`. Both now route through the shared
helper.

## What changes are included in this PR?

- `datafusion_common::utils::split_vec_min_alloc`: the shared helper,
with `shrink_to_fit` on the emitted prefix.
- `datafusion-physical-plan`: the duplicate helper is removed;
`bytes.rs`, `primitive.rs` and `bytes_view.rs` use the shared one.
- `datafusion-functions-aggregate`: `MinMaxStructAccumulator` and
`MinMaxBytesAccumulator` use it in `emit_to`.

This supersedes #22205, whose `ByteViewGroupValueBuilder::take_n` change
is included here.

## Are these changes tested?

Yes. Unit tests for the helper (both branches and the boundaries) plus
the existing `take_n` and `min_max` tests pass.

## Are there any user-facing changes?

No.

Subject: [PATCH 076/878] Support transparent ExecutionPlan downcasts (#22559)

## Which issue does this PR close?

- Closes #22557.

## Rationale for this change

DataFusion 54 changed `ExecutionPlan` downcasting to use the `Any`
supertrait directly. That removes `ExecutionPlan::as_any`, which had
also served as a customization point for wrapper nodes: wrappers could
identify as themselves internally while exposing the wrapped plan type
to normal downcast-based inspection.

This draft PR proposes one possible fix: add an explicit
`ExecutionPlan::downcast_delegate()` hook for wrapper nodes that want
their public `ExecutionPlan` downcast identity to be delegated to
another plan.

The proposed behavior intentionally preserves the old `as_any` override
semantics: when a node opts into downcast delegation, intermediate
delegating wrappers are invisible to `dyn ExecutionPlan::is::<T>()` and
`downcast_ref::<T>()`. A different "dual identity" model, where wrappers
can downcast both as themselves and as their delegates, may also be
useful, but that would be a new behavior rather than a compatibility
fix.

This is only a suggested implementation for the linked issue. Other
solution proposals, including different API names or a different shape
for the hook, are very welcome.

## What changes are included in this PR?

- Adds `ExecutionPlan::downcast_delegate()` with a default
implementation returning `None`.
- Updates `dyn ExecutionPlan::is::<T>()` and `downcast_ref::<T>()` to
delegate to `downcast_delegate()` when present, otherwise use the
current concrete plan type.
- Documents that `downcast_delegate()` is only for type introspection
and is independent from `children()` / plan traversal.
- Adds tests for direct and nested downcast-delegating wrappers,
including that intermediate delegating wrappers remain invisible to
normal downcast-based inspection.

An alternative API shape would make every plan expose an explicit
downcast target. A concrete spelling could make the self-target case
explicit:

```rust
enum DowncastTarget<'a> {
    SelfTarget,
    Plan(&'a dyn ExecutionPlan),
}

fn downcast_target(&self) -> DowncastTarget<'_> {
    DowncastTarget::SelfTarget
}

pub fn downcast_ref<T: ExecutionPlan>(&self) -> Option<&T> {
    match self.downcast_target() {
        DowncastTarget::Plan(target) => target.downcast_ref::<T>(),
        DowncastTarget::SelfTarget => (self as &dyn Any).downcast_ref(),
    }
}
```

That frames every plan as having a public downcast target, which is
close to the old `as_any` mental model. A simpler conceptual version
would be `fn downcast_target(&self) -> &dyn ExecutionPlan` with the
default target being `self`, but the real helper still needs an explicit
self-target base case to avoid recursing forever. This PR keeps the
primary proposal as an explicit `Option`-based opt-in.

## Are these changes tested?

Yes.

- `cargo test -p datafusion-physical-plan --lib`
- `cargo fmt --all -- --check`
- `git diff --check`

## Are there any user-facing changes?

Yes. This adds a new public `ExecutionPlan` trait method with a default
implementation, and it changes `ExecutionPlan` downcast helpers to honor
wrappers that explicitly opt into delegating public downcast identity.

Subject: [PATCH 077/878] feat: lower repartition_file_min_size default from 10
 MiB to 1 MiB (#22439)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

`repartition_file_min_size` gates how aggressively `repartitioned()`
splits file groups by byte range to fan a scan out across
`target_partitions` worth of cores. At 10 MiB the default leaves several
SF1-sized dimension tables (TPC-H \`part\` ≈ 24 MiB, TPC-DS
\`customer_address\` ≈ 7 MiB, …) on a single partition, so any CPU-bound
per-batch work in the scan (filter eval, dictionary expansion, etc.) is
single-threaded even when the cluster has plenty of idle cores.

At 1 MiB those same files split cleanly into \`target_partitions\` byte
ranges. The cost (more \`open()\` calls, more metadata loads) is small
in absolute terms (≤10 extra opens per file in the worst case, each
amortised over the row-group / page-index reads) and the existing knob
is still available for workloads where it matters.

## Benchmark numbers

12-core, SF1, with the existing dynamic-filter-pushdown defaults
preserved:

| Suite | default (10 MiB) | with this PR (1 MiB) |
|---|---|---|
| TPC-H total | 841 ms | 776 ms |
| TPC-H Q22 | ~30 ms | ~17 ms |
| TPC-DS total | 11.0 s | 11.1 s |
| ClickBench total | 21.7 s | 19.0 s |

## Test plan

- [x] \`cargo test --test sqllogictests\` — all 472 files pass after the
information_schema snapshot and a csv_files reset.
- [ ] \`run benchmarks\`

For example, for a query such as `SELECT * FROM t ORDER BY timestamp DESC LIMIT 10`, the optimizer will attempt to push down the current top 10 timestamps that the TopK operator references into the file scans. This means that if we already have 10 timestamps in the year 2025 any files that only have timestamps in the year 2024 can be skipped / pruned at various stages in the scan. The config will suppress `enable_join_dynamic_filter_pushdown`, `enable_topk_dynamic_filter_pushdown` & `enable_aggregate_dynamic_filter_pushdown` So if you disable `enable_topk_dynamic_filter_pushdown`, then enable `enable_dynamic_filter_pushdown`, the `enable_topk_dynamic_filter_pushdown` will be overridden.                                                                                                                                                                                                                                                                                                                                                                                     |

This applies to both in-memory partitions and FileSource's file groups (1 group is 1 partition). For FileSources, only Parquet and CSV formats are currently supported. If set to `true` for a FileSource, all files will be repartitioned evenly (i.e., a single large file might be partitioned into smaller chunks) for parallel scanning. If set to `false` for a FileSource, different files will be read in parallel, but repartitioning won't happen within a single file. If set to `true` for an in-memory source, all memtable's partitions will have their batches repartitioned evenly to the desired number of `target_partitions`. Repartitioning can change the total number of partitions and batches per partition, but does not slice the initial record tables provided to the MemTable on creation.                                                                                                                                                                                                                                                                                                                      |

Subject: [PATCH 078/878] Guard date_trunc lower-bound truncation (#22303)

## Which issue does this PR close?

- Closes #22214.

## Rationale for this change

Truncating a near-lower-bound nanosecond timestamp to a coarser calendar
unit can produce a timestamp outside Arrow's nanosecond range.
`date_trunc_coarse` already used fallible timestamp conversion, but it
unwrapped the final conversion back to nanoseconds and could panic.

## What changes are included in this PR?

- Convert the final out-of-range truncation case into a DataFusion
execution error.
- Add a small string helper for user-facing granularity names in the
error.
- Add a unit regression and a sqllogictest regression for lower-bound
nanosecond truncation.

## Are these changes tested?

Yes:

- `cargo fmt --check`
- `git diff --check`
-
`CARGO_TARGET_DIR=/home/sean/Projects/datafusion-runtime-set-nonascii/target
CARGO_BUILD_JOBS=2 cargo test -p datafusion-functions --lib
date_trunc_out_of_range_lower_bound_returns_error`
-
`CARGO_TARGET_DIR=/home/sean/Projects/datafusion-runtime-set-nonascii/target
CARGO_BUILD_JOBS=2 cargo test -p datafusion-sqllogictest --test
sqllogictests -- date_trunc_boundaries.slt`
-
`CARGO_TARGET_DIR=/home/sean/Projects/datafusion-runtime-set-nonascii/target
CARGO_BUILD_JOBS=2 cargo clippy -p datafusion-functions --lib -- -D
warnings`

## Are there any user-facing changes?

Instead of panicking, out-of-range `date_trunc` results now return an
error.

Subject: [PATCH 079/878] perf(physical-optimizer): skip ensure_distribution
 rebuild when children are unchanged (#22521)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22520.

## Rationale for this change

`ensure_distribution` in
`datafusion/physical-optimizer/src/ensure_requirements/enforce_distribution.rs`
unconditionally calls `plan.with_new_children(children_plans)` after
collecting the (possibly redistributed) children, even when none of
those children were actually replaced. For nodes like `ProjectionExec`,
that path runs through `try_new` and recomputes the schema, equivalence
properties, output ordering, and output partitioning, then allocates a
new `Arc<dyn ExecutionPlan>`. When every child Arc is pointer-identical
to the input, that work produces a logically identical node — pure
overhead.

The cost is amplified by two factors:

1. **Plan depth.** Workloads dominated by point queries (no join /
aggregate / unmet ordering — i.e. nothing for `ensure_distribution` to
inject a `RepartitionExec` or `SortExec` for) hit this wasted rebuild at
every node in the plan. A 5–30 deep `ProjectionExec` stack pays the cost
N times.
2. **Schema width.** Most steps inside `ProjectionExec::try_new` are
`O(num_columns)`: per-column `data_type` / `nullable` lookup to build
the new schema, per-column remapping of equivalence classes through the
projection mapping, and per-column lookup when rewriting
`PhysicalSortExpr`s into the output ordering. Wide schemas (tens of
columns) make every wasted rebuild proportionally heavier.

Profiling a production point-query workload (wide schemas, deep
`ProjectionExec` stacks) showed `ProjectionExec::with_new_children` as
the single largest cost inside `ensure_distribution`:

- `ensure_distribution` total: 2.87s of a 60s CPU sample
- `ProjectionExec::with_new_children`: 1.94s (56% of the rule)
- `SortExec::with_new_children`: 0.11s
- Other ExecutionPlan nodes: 0.82s

## What changes are included in this PR?

After collecting `children_plans`, compare each new child Arc with the
original via `Arc::ptr_eq`. When every child is unchanged, reuse the
existing `plan` Arc and skip `with_new_children`. The `UnionExec` to
`InterleaveExec` special case still runs first because it intentionally
produces a new node even when child Arcs are unchanged.

This relies on the fact that `ensure_distribution` already produces
pointer-identical Arcs for children that need no redistribution (it
threads the original Arc through unchanged), so `Arc::ptr_eq` precisely
distinguishes "rewritten" from "untouched" children at O(1) per child.

## Are these changes tested?

Yes. The existing `enforce_distribution` suite passes unchanged (66/66):

```
cargo test --release -p datafusion --test core_integration -- physical_optimizer::enforce_distribution
```

The behavior is observable only as a CPU reduction; correctness is
preserved because `ExecutionPlan` nodes are immutable, so reusing the
original Arc produces the same plan tree as
`with_new_children(unchanged_children)` would have, just without the
schema / ordering / equivalence / partitioning recomputation.

## Are there any user-facing changes?

No. Same plans, lower planning time.

## Micro-benchmark

Plan shape: 30-deep `ProjectionExec` stack over a sorted parquet scan,
5000 iterations.

- Without fix: 852.74 ms total, 170.55 us/call
- With fix:    296.81 ms total, 59.36 us/call
- ~2.87x speedup, -65% CPU per call

Wider schemas (more projection expressions per node) widen the gap
further because each skipped `with_new_children` avoids more
O(num_columns) work.

Subject: [PATCH 080/878] fix: Avoid precision loss for `atan2` with integer
 args (#22516)

## Which issue does this PR close?

- Closes #22514.

## Rationale for this change

`atan2` defined two input signatures: `(Float32, Float32)` and
`(Float64, Float64)` (in that order). That meant that integer inputs
were coerced into `Float32` values, which lead to incorrect results:
`atan2(1, 1000000)` resulted in less precision than `atan2(1.0,
1000000.0)`; the results for the former were also inconsistent with the
behavior of `atan2` in Postgres and DuckDB.

Fix this by only using the `Float32` path when given two` Float32`
inputs; for other inputs, we should use `Float64`. This avoids rounding
for large integer inputs (`Float32` has only 24 mantissa bits, so larger
integers would get rounded).

## What changes are included in this PR?

* Fix `atan2` signature to only take the `Float32` code path for two
`Float32` inputs
* Update SLT, add new SLT test

## Are these changes tested?

Yes, new test added.

## Are there any user-facing changes?

Yes: the return type and semantics of `atan2` in some circumstances has
changed. `atan2` will now only be computed in `Float32` when passed two
`Float32` values. In all other cases, the computation will be done in
`Float64` and a `Float64` value will be returned.

Subject: [PATCH 081/878] Return None for cardinality overflow (#22309)

## Which issue does this PR close?

Closes #22232
(cc @Dandandan )

## Rationale for this change

Prevent `Interval::cardinality()` from overflowing on the full `i64`
range.

## What changes are included in this PR?

- use `checked_add(1)` instead of `+ 1`
- add a regression test for the full `i64` range

## Are these changes tested?

- `cargo fmt --all --check`
- `cargo test -p datafusion-expr-common
test_cardinality_full_i64_range_does_not_overflow --lib`
- `cargo clippy --all-targets --all-features -- -D warnings` could not
run locally because `cmake` is not installed

## Are there any user-facing changes?

- No

Subject: [PATCH 082/878] Fix correlated subquery empty defaults for regr_count
 and approx_distinct (#22319)

## Which issue does this PR close?

- Closes #22317.

## Rationale for this change

Correlated scalar subqueries with ungrouped aggregates are decorrelated
into joins. For unmatched outer rows, the rewritten join naturally
produces NULLs on the right side, so DataFusion has compensation logic
for aggregates that should return a non-NULL value on empty input.

That compensation previously special-cased `count` by name. As a result,
other aggregates with non-NULL empty-input results, such as `regr_count`
and `approx_distinct`, incorrectly returned NULL after decorrelation.

## What changes are included in this PR?

This PR updates decorrelation to use each aggregate UDF's
`default_value()` instead of hard-coding `count`.

It also adds empty-input defaults for:

- `regr_count`: `UInt64(0)`
- `approx_distinct`: `UInt64(0)`

Regression coverage is added for correlated scalar subqueries using
these aggregates in projection expressions and filters.

## Are these changes tested?

Yes.

```bash
cargo fmt --all
cargo test -p datafusion-sqllogictest --test sqllogictests -- subquery.slt
```

## Are there any user-facing changes?

Yes. Queries using `regr_count` or `approx_distinct` in correlated
scalar subqueries now return `0` for unmatched outer rows instead of
`NULL`, matching the aggregate behavior on empty input.

Subject: [PATCH 083/878] refactor: port HashExpr proto hooks (#22502)

## Which issue does this PR close?

- Closes #22432.

## Rationale for this change

`HashExpr` is part of the physical expression proto cleanup tracked by
#22418. Its protobuf serialization should live with the expression
implementation instead of in the central proto downcast chains, matching
the hook pattern added in #21929.

## What changes are included in this PR?

This adds `HashExpr`'s `PhysicalExpr::try_to_proto` override and a
feature-gated inherent `HashExpr::try_from_proto`. The existing
`PhysicalHashExprNode` wire shape is preserved, including `expr_id:
None`, while `datafusion-proto` now routes `ExprType::HashExpr` decoding
through the hook and no longer has a central `HashExpr` serialization
arm. `datafusion-physical-plan` now exposes a `proto` feature so the
hook code only compiles when proto support is requested.

## Are these changes tested?

Yes. Added focused direct hook tests for encoding, decoding, and
rejecting a wrong `expr_type`.

Commands run:
- `cargo fmt --all -- --check`
- `cargo check -p datafusion-physical-plan`
- `cargo test -p datafusion-physical-plan --features proto
hash_expr_try`
- `cargo test -p datafusion-proto --test proto_integration
cases::roundtrip_physical_plan::roundtrip_hash_expr`
- `cargo check -p datafusion-proto`
- `cargo clippy -p datafusion-physical-plan --features proto
--all-targets -- -D warnings`
- `cargo clippy -p datafusion-proto --all-targets -- -D warnings`

## Are there any user-facing changes?

No. This preserves the existing protobuf representation.

Subject: [PATCH 084/878] feat: Plumb Parquet virtual columns (row_number)
 through TableSchema and ParquetOpener (#22026)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #20135 (epic: virtual / metadata columns). Does not close that
epic; see [this
comment](https://github.com/apache/datafusion/issues/20135#issuecomment-4381652523)
describing the scope split.
- Revives #20133 (auto-closed stale) — same core plumbing, credit to
@jkylling.
- Unblocks apache/datafusion-comet#3432 (remove native_datafusion
fallback for Spark's `_tmp_metadata_row_index`).

## Rationale for this change

arrow-rs 57.1.0+ supports Parquet virtual columns (`row_number`,
`row_group_index`) via `ArrowReaderOptions::with_virtual_columns`, and
DataFusion pins a new-enough arrow-rs for the API to be available.
DataFusion does not yet plumb the option through `ParquetOpener`, so
consumers (notably Comet) cannot project Spark's
`_tmp_metadata_row_index` through the native_datafusion scan path.

This PR adds the minimal opener-boundary plumbing so `TableSchema` can
carry virtual columns and the Parquet reader produces them. UX /
SQL-layer surface for virtual columns stays deferred to the epic in
#20135 — this follows the same framing alamb blessed for #20071 (the
`input_file_name()` UDF).

## What changes are included in this PR?

### `TableSchema` / `TableSchemaBuilder`

- `TableSchemaBuilder::with_virtual_columns(impl Into<Fields>)` setter,
picking up #22496's "follow-up" hook: build with `[file, partition,
virtual]` ordering in a single concatenation. Setter order on the
builder does not matter; the layout is fixed.
- Virtual columns are stored as `arrow::datatypes::Fields` (matches the
`table_partition_cols` storage main switched to in #22496 — no
`Arc<Vec<_>>` indirection, shareable zero-copy, immutable so the
in-place mutation panic class is structurally impossible).
- `TableSchema::virtual_columns()` getter (`&Fields`).
- `TableSchema::schema_without_virtual_columns()` — file + partition
schema used by pushdown-planning paths that can't evaluate virtual-col
refs.
- `TableSchema::with_virtual_columns(...)` chainable convenience
preserved for API ergonomics; routes through the builder so it preserves
any partition columns already on the source `TableSchema`.
- The deprecated `TableSchema::with_table_partition_cols` was extended
to preserve virtual columns when routing through the builder (it would
otherwise drop them for callers still on the deprecated path).
- Collision check (`virtual` vs `file`, `virtual` vs `partition`,
duplicates within `virtual`) lives in `TableSchemaBuilder::build()` as a
`debug_assert!` so release builds pay nothing; setter order is
irrelevant because the check runs at `build()`.

### `ParquetOpener` / `ParquetSource`

- `ParquetOpener` forwards the fields to
`ArrowReaderOptions::with_virtual_columns`; augments the schemas passed
to the expr-adapter / simplifier with virtual fields so virtual-col refs
identity-rewrite; the virtual-col stripping (substitute with null
literals for `ProjectionMask::roots`, append to `stream_schema` so
`reassign_expr_columns` resolves them by name) lives inside
`DecoderProjection::try_new` (the abstraction #22398 introduced),
reached via a new `Option<&VirtualColumnsState>` parameter so the
zero-virtual-column common path is unchanged.
- New `ParquetVirtualColumn` enum with `TryFrom<&FieldRef>` (in
`datasource-parquet::virtual_column`) gates which arrow-rs virtual
extension types are accepted. Currently only `RowNumber`; adding a
variant (e.g. `RowGroupIndex`) is a compile-time obligation. Replaces a
runtime string-allowlist so the contract lives in the type system.
- `ParquetSource::try_pushdown_filters` classifies filters against
`schema_without_virtual_columns()` so predicates referencing virtual
columns are reported as `PushedDown::No` and the `FilterExec` stays
above the scan — arrow-rs's `RowFilter` addresses parquet leaves only
and can't evaluate virtual-column refs, so silently pushing them would
produce wrong results.
- Defensive check in the opener: `build_virtual_columns_state` (run once
per scan partition at morselizer-build time) errors when
`pushdown_filters=true` and the predicate references a virtual column,
with a clear remediation message pointing at `try_pushdown_filters`.
This catches callers that bypass the optimizer and set the predicate on
`ParquetSource` directly. Returns a `Result` (not a panic) so the
contract is enforced in release builds too.
- `VirtualColumnsState` is constructed once per scan partition:
validates the extension-type allowlist, precomputes the
`null_replacements` HashMap and the `logical_schema_with_virtual`
schema. Each file's open path then borrows the precomputed state via
`Arc`.

### Cargo

- `arrow-schema` added as a direct dep (previously transitive via
`arrow`) so the enum references `RowNumber::NAME` from arrow-rs (via
`arrow_schema::extension::ExtensionType`) instead of hardcoding the
string.

### Explicitly **not** in scope (follow-ups)

- `ListingTable` / SQL-layer surface
- `ParquetSource::with_virtual_columns`
- `RowGroupIndex` support (the enum has a deliberate-rejection test for
it)
- Removing the `TableSchema` chainable convenience setter; it could be
deprecated in a follow-up to align fully with #22496's builder-only
direction

## Are these changes tested?

Yes.

**`opener/mod.rs`** (10 new tests, in a `virtual_columns` submodule):

- `test_row_index_basic` — single row group, select data + row_number.
- `test_row_index_projection_only` — select only row_number.
- `test_row_index_multi_row_group` — 3 × 100 rows, verify absolute
0..300 across boundaries.
- `test_row_index_with_row_group_skip` — predicate stats-prunes the
middle row group; verify row numbers stay absolute (0..100 ++ 200..300).
Critical correctness gate for Spark (and for apache/arrow-rs#8863).
- `test_row_index_with_partition_cols` — partition + virtual + data
columns compose correctly.
- `test_row_index_nullable_int64` — nullability flag flows through
unchanged (matches Spark's `_tmp_metadata_row_index` declaration).
- `test_unsupported_virtual_extension_type_rejected` — using
`RowGroupIndex` (a real arrow-rs type deliberately not in the enum yet)
errors with `NotImplemented` instead of silently forwarding.
- `test_row_index_predicate_pushdown_mixed_or_errors` /
`_virtual_only_errors` / `_allowed_when_pushdown_disabled` — exercise
the opener's defensive check for virtual-col predicate refs with
`pushdown_filters=true`, and confirm the `pushdown_filters=false` path
is unaffected.

**`source.rs`**: `test_try_pushdown_filters_rejects_virtual_column_refs`
pins the planner-boundary contract — file-col filters are
`PushedDown::Yes`, virtual-only and mixed `OR` filters are
`PushedDown::No`.

**`virtual_column.rs`** (3 new tests): `TryFrom<&FieldRef>` for valid
`RowNumber`, missing-extension-type, and unsupported-extension-type
(real `RowGroupIndex`) inputs.

**`table_schema.rs`** (5 new tests): `[file, partition, virtual]` layout
regardless of builder-call order; `debug_assert!` collision panics for
virtual-vs-file, virtual-vs-partition (both setter orderings), and
duplicates within virtual.

`cargo test -p datafusion-datasource-parquet --all-features` (137
passing) and `cargo test -p datafusion-datasource` (148 passing). `cargo
clippy -p datafusion-datasource-parquet -p datafusion-datasource
--all-targets --all-features -- -D warnings` is clean.

## Are there any user-facing changes?

Public API additions:

- `TableSchemaBuilder::with_virtual_columns(impl Into<Fields>)`
- `TableSchema::with_virtual_columns(Vec<FieldRef>)` (chainable
convenience that routes through the builder)

Subject: [PATCH 085/878] Port CastExpr to proto hooks (#22569)

## Which issue does this PR close?

- Closes #22428.

## Rationale for this change

`CastExpr` protobuf serialization is currently handled by the central
physical expression downcast chain. This PR migrates it to the
per-expression `try_to_proto` / `try_from_proto` hooks, following the
existing `Column` / `LikeExpr` pattern.

## What changes are included in this PR?

- Adds `CastExpr::try_to_proto` in the `impl PhysicalExpr for CastExpr`
block.
- Adds inherent `CastExpr::try_from_proto` for decoding
`PhysicalCastNode`.
- Routes `ExprType::Cast` decoding through the new hook.
- Removes the old central `CastExpr` serialization arm from
`to_proto.rs`.
- Adds direct hook tests for successful encode/decode and bad-input
cases.

## Are these changes tested?

Yes

## Are there any user-facing changes?

No. The protobuf wire format for `CastExpr` remains unchanged.

Subject: [PATCH 086/878] ci(breaking-change-detector): don't use
 `maintain-one-comment` and instead do it manually (#22568)

the comment and label for breaking change detector is not working for 8
days already, (it was noticed by @neilconway)

after searching the issue is that
[`actions-cool/maintain-one-comment`](https://github.com/actions-cool/maintain-one-comment)
that we used was compromised and was removed from github.

we did not used the malicious commit fortunately.

this change the comment logic to be manual instead of using that action

Subject: [PATCH 087/878] refactor: cache schema_without_virtual_columns and
 remove TableSchema::with_virtual_columns (#22600)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

Followup to #22026 — addresses two review comments from @adriangb that
landed after the PR was already in the merge queue.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Two pieces of feedback on the `TableSchema` API introduced in #22026:

1.
https://github.com/apache/datafusion/pull/22026#discussion_r3319225261 —
`TableSchema::with_virtual_columns` shouldn't exist as a non-deprecated
counterpart to the already-deprecated
`TableSchema::with_table_partition_cols`. Callers should use
`TableSchemaBuilder` directly. Every existing call site already does, so
the method has no users.
2.
https://github.com/apache/datafusion/pull/22026#discussion_r3319230237 —
`schema_without_virtual_columns` was rebuilding the schema on every
call. It can be computed once at construction and returned by reference,
matching the convention used by every other accessor on `TableSchema`
(`file_schema`, `table_schema`, `table_partition_cols`,
`virtual_columns` all return `&`).

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Remove `TableSchema::with_virtual_columns`. Callers must use
`TableSchemaBuilder::with_virtual_columns` (no in-tree callers needed
updating).
- Cache `schema_without_virtual_columns` on `TableSchema`, computed once
in `TableSchemaBuilder::build`. When there are no virtual columns the
cached field shares the same `Arc` as `table_schema`.
- Accessor `schema_without_virtual_columns(&self)` now returns
`&SchemaRef` instead of an owned `SchemaRef`, matching the rest of the
struct's accessors. Updated the one in-tree caller in
`datasource-parquet/src/source.rs`.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes — covered by the existing `table_schema` unit tests and the
`datasource-parquet` test suite, all of which still pass. The change is
a refactor with no behavioral difference: the cached schema produced in
`build()` is byte-for-byte identical to what the previous accessor
allocated on each call.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Two API changes against the `TableSchema` surface added in #22026 (which
has not been released):

- `TableSchema::with_virtual_columns` removed. Use
`TableSchemaBuilder::with_virtual_columns` instead.
- `TableSchema::schema_without_virtual_columns` return type changed from
`SchemaRef` to `&SchemaRef`. Callers that need an owned value should
`Arc::clone` the result.

Subject: [PATCH 088/878] refactor(physical-expr-common): add proto helpers for
 the recurring shapes in #22418, port already-migrated exprs (#22596)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Part of #22418 / follow-up to #22513.

## Rationale for this change

Every PR migrating a `PhysicalExpr` to `try_to_proto` / `try_from_proto`
under #22418 re-implements the same two shapes that don't fit the
existing helpers from #22513:

1. The outer `match &node.expr_type { ... }` that opens every
`try_from_proto`:
   ```rust
   let try_cast = match &node.expr_type {
Some(protobuf::physical_expr_node::ExprType::TryCast(x)) => x.as_ref(),
_ => return internal_err!("PhysicalExprNode is not a TryCastExpr"),
   };
   ```
2. The hand-rolled "missing required field 'X'" error for non-expression
fields like `arrow_type` on `CastExpr` / `TryCastExpr`.

Each shape leaks across the 7+ remaining open migration PRs. Adding
small helpers in `physical-expr-common` keeps the per-expression diff
minimal and the error messages consistent.

## What changes are included in this PR?

**Commit 1 — `feat(physical-expr-common): add proto helpers ...`**

Two new helpers in `datafusion-physical-expr-common`, both gated on
`feature = "proto"`:

- `expect_expr_variant!` macro (re-exported at crate root) — matches
`Option<ExprType>`, returns inner payload, errors with
`"PhysicalExprNode is not a {variant}"`.
- `proto_decode::require_proto_field<T>(opt, expr_name, field)` —
mirrors `decode_required_expression` for non-`PhysicalExprNode` fields.

Five unit tests cover the helpers (success + the two reject paths for
the macro).

**Commit 2 — `refactor(physical-expr): adopt new proto helpers in
already-migrated expressions`**

Ports every expression already on the new hooks:

- `Column`, `BinaryExpr` (originally #21929)
- `LikeExpr` (#22471)
- `InListExpr` (#22503)
- `NegativeExpr` (#22483)

`BinaryExpr` additionally adopts `decode_required_expression` for its
legacy `l`/`r` arms and `encode_children_expressions` /
`decode_children_expressions` for the linearized `operands` path,
removing two more hand-rolled "missing required field" strings.

One existing test changes assertion text — `InListExpr`'s
rejected-variant message was the only one using the article "an" instead
of "a"; the macro emits article-free "a {Variant}" uniformly.

The two commits are stacked for review: commit 1 is the helper addition
only; commit 2 is the adoption. Either can be reviewed in isolation.

## Are these changes tested?

Yes:

- `cargo test -p datafusion-physical-expr-common --features proto` — new
helper unit tests pass.
- `cargo test -p datafusion-physical-expr --features proto proto_tests`
— 23 / 23 per-expression proto tests pass (1 assertion-string update in
InList).
- `cargo test -p datafusion-proto --test proto_integration` — 173 / 173
pass; no wire-format change.
- `cargo clippy --all-targets --all-features -- -D warnings` clean on
the touched crates.

## Are there any user-facing changes?

No. New API surface in `datafusion-physical-expr-common` (helpers gated
on `feature = "proto"`); no change to serialized output. The macro
`expect_expr_variant!` is exported at the crate root.

Subject: [PATCH 089/878] docs: clarify difference between
 try_cast_literal_to_type and ScalarValue::cast_to (#22592)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #22577 (consolidate `ScalarValue` cast implementations).

## Rationale for this change

I have been confused about the difference between `ScalarValue::cast_to`
and `try_cast_literal_to_type` -- so after some research I would like to
make the difference clearer


## What changes are included in this PR?

Document on each function how it differs from the other, so the choice
is obvious from the docs alone.

## Are these changes tested?

by CI

## Are there any user-facing changes?

Doc comments only. No code or API changes.

Subject: [PATCH 090/878] Port NotExpr proto hooks (#22463)

## Which issue does this PR close?

- Closes #22422.

## Rationale for this change

`NotExpr` still used the central physical expression protobuf downcast
path. Moving it to the expression-level proto hook keeps it aligned with
the newer serialization pattern and reduces the special-case branching
in the shared conversion code.

## What changes are included in this PR?

- Move `NotExpr` protobuf serialization into its `try_to_proto` hook.
- Add `NotExpr::try_from_proto` and route decode through it.
- Remove the old central `to_proto` downcast branch for `NotExpr`.

## Are these changes tested?

Yes. I ran:

- `cargo fmt --all -- --check`
- `cargo check -p datafusion-physical-expr --features proto`
- `cargo check -p datafusion-proto`
- `cargo test -p datafusion-proto --test proto_integration
roundtrip_filter_with_not`
- `git diff --check`

## Are there any user-facing changes?

No. This is an internal proto serialization refactor and should not
change query behavior or public APIs.

 `EliminateOuterJoin` (#22534)

## Which issue does this PR close?

- Closes #22531.

## Rationale for this change

`EliminateOuterJoin` looks for plans with a `Filter` directly above a
`Join`. For most queries, that is the right plan shape, because
`PushdownFilter` will typically place the filters that are useful for
outer join elimination directly on top of the relevant `Join`. However,
some plans don't follow this shape, for at least two reasons:

1. Volatile expressions can interfere with filter pushdown
2. `OptimizeProjections` might insert a `Projection` between the
`Filter` and `Join`

Notably, we run into case (2) in TPC-DS Q49; we currently fail to
convert three outer joins to inner joins for that reason.

We can handle this by teaching `EliminateOuterJoins` to descend through
one or more intermediate `Projection` nodes, rewriting the filter
predicate as it goes to account for the effect of the projection.

## What changes are included in this PR?

* Teach `EliminateOuterJoins` to descend through one or more
`Projection` nodes
* Refactor various code in `eliminate_outer_joins.rs`, improve comments
* Add unit tests
* Add SLT tests

## Are these changes tested?

Yes, new tests added. Manually verified that we fail to eliminate the
outer joins in TPC-DS Q49 without this change and succeed on doing so
with this change.

## Are there any user-facing changes?

More effective outer join query optimization.

+/// Attempt to simplify outer joins when filters make their null-padded
+/// rows impossible to observe.
 ///
-/// Attempt to replace outer joins with inner joins.
+/// Outer joins are generally more expensive than inner joins and can block
+/// predicate pushdown and other optimizations. When a filter above an outer
+/// join removes every row the join would add for unmatched input rows, the
+/// join can be changed to a cheaper join type.
 ///
-/// Outer joins are typically more expensive to compute at runtime
-/// than inner joins and prevent various forms of predicate pushdown
-/// and other optimizations, so removing them if possible is beneficial.
+/// For example:
 ///
-/// Inner joins filter out rows that do match. Outer joins pass rows
-/// that do not match padded with nulls. If there is a filter in the
-/// query that would filter any such null rows after the join the rows
-/// introduced by the outer join are filtered.
+/// ```sql
+/// SELECT ...
+/// FROM a LEFT JOIN b ON ...
+/// WHERE b.xx = 100
+/// ```
 ///
-/// For example, in the `select ... from a left join b on ... where b.xx = 100;`
+/// For unmatched rows from `a`, the LEFT JOIN would produce a row with
+/// `b.xx` set to NULL. The predicate `b.xx = 100` does not pass for those
+/// rows, so the query does not need the LEFT JOIN's null-padded output and
+/// the join can be rewritten as an inner join.
 ///
-/// For rows when `b.xx` is null (as it would be after an outer join),
-/// the `b.xx = 100` predicate filters them out and there is no
-/// need to produce null rows for output.
+/// The same reasoning can also simplify FULL joins to LEFT, RIGHT, or INNER
+/// joins when filters remove the rows padded on one or both sides.
 ///
-/// Generally, an outer join can be rewritten to inner join if the
-/// filters from the WHERE clause return false while any inputs are
-/// null and columns of those quals are come from nullable side of
-/// outer join.
+/// This rule looks for a filter above an outer join:
+///
+/// ```text
+/// Filter(predicate)
+///   Join(LEFT/RIGHT/FULL)
+/// ```
+///
+/// It also handles plan shapes where projection pruning has inserted one or
+/// more Projection nodes between the filter and join:
+///
+/// ```text
+/// Filter(predicate over projection output)
+///   Projection(...)
+///     ...
+///       Join(LEFT/RIGHT/FULL)
+/// ```
+///
+/// In the projection case, the rule rewrites a copy of the predicate through
+/// each Projection so it can analyze the predicate against the Join inputs.
+/// The original filter predicate and Projection nodes are preserved when the
+/// plan is rebuilt.

Subject: [PATCH 092/878] fix: LIKE 'prefix%' pruning fails on Utf8View and
 LargeUtf8 columns (#22562)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22561.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

LIKE 'prefix%' predicates on `Utf8View` and `LargeUtf8` columns produce
`predicate_evaluation_errors`, causing row group and page index pruning
to be skipped entirely.

The cause is `build_like_match` always synthesizes bound literals as
`ScalarValue::Utf8`, regardless of the actual column type. When the
column is `Utf8View` or `LargeUtf8`, the subsequent comparison between
the Utf8-typed bound and the min/max statistics (which use the column's
native type) fails with a type mismatch error.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Updated `build_like_match` to use `string_literal_as` with the
column's data_type() instead of hardcoding `ScalarValue::Utf8` for the
lower/upper bound literals.
- Added a regression test (prune_like_prefix) that verifies LIKE prefix
pruning works correctly on UTF8 columns with expected row group
statistics pruning and zero predicate errors.

## Are these changes tested?

Yes.

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 093/878] perf: array-free fast paths for
 `ScalarValue::cast_to` (#22576)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of https://github.com/apache/datafusion/issues/22577
- Spun out of review discussion on #22562.

## Rationale for this change

`ScalarValue::cast_to_with_options` always builds a single-row array and
runs the arrow cast kernel, even for trivial conversions. For two very
common cases — casting a value to its own type, and converting between
the string types — that array allocation and kernel dispatch is pure
overhead.

## What changes are included in this PR?

Two array-free fast paths in `cast_to_with_options` that produce
**exactly** the same result as the existing array + arrow-kernel path:

Everything else still goes through the existing arrow path, so behavior
is unchanged.

## Are these changes tested?

Yes — there are new tests added

## Are there any user-facing changes?

No. `cast_to` / `cast_to_with_options` return the same results as
before, just faster for these cases. No API changes.

Subject: [PATCH 094/878] feat(sql): Postgres-style `EXPLAIN (...)` option list
 (#21768)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #.

(Follow-up to #21160, which introduced per-category metric filtering via
session config. This PR lets users reach those knobs inline from the
EXPLAIN statement.)

## Rationale for this change

#21160 added metric categories (`Rows`, `Bytes`, `Timing`,
`Uncategorized`) and a verbosity level (`Summary`, `Dev`) to
DataFusion's metrics, exposed today only via session config:

- `datafusion.explain.analyze_categories`
- `datafusion.explain.analyze_level`

Users have to `SET` these out-of-band before running `EXPLAIN ANALYZE`,
which is awkward for ad-hoc debugging. Postgres solves this with its
parenthesized option list:

```sql
EXPLAIN (ANALYZE, BUFFERS, VERBOSE, SETTINGS, WAL) SELECT ... ;
```

This PR adds the same ergonomics to DataFusion, mapping option names to
DataFusion's existing semantics rather than Postgres's buffer/WAL model.

## What changes are included in this PR?

**Parser.** On dialects whose `supports_explain_with_utility_options()`
returns true (the default `GenericDialect`, `PostgreSqlDialect`,
`DuckDbDialect`, etc.), `DFParser::parse_explain` delegates to
sqlparser's `pub fn parse_utility_options()` and feeds the result
through a new `ExplainStatementOptions::from_utility_options`. The
legacy keyword form (`EXPLAIN ANALYZE VERBOSE FORMAT tree ...`) is
unchanged.

**Normalized option type.** A new `ExplainStatementOptions` in
`datafusion-common` captures the knobs parsed from either form. Argument
parsing reuses existing `ExplainFormat::from_str`,
`ExplainAnalyzeCategories::from_str`, and `MetricType::from_str`.

**Options accepted:**

| Option | Argument | Effect |
| --------- | ---------------- |
--------------------------------------------------------------------- |
| `ANALYZE` | bool, default T | Same as keyword `ANALYZE` |
| `VERBOSE` | bool, default T | Same as keyword `VERBOSE` |
| `FORMAT` | ident/string | `indent` / `tree` / `pgjson` / `graphviz` |
| `METRICS` | string | `'all'`, `'none'`, or comma-separated
`rows,bytes,timing,uncategorized` |
| `LEVEL` | ident/string | `summary` or `dev` |
| `TIMING` | bool | Sugar: toggles inclusion of the `timing` category |
| `SUMMARY` | bool | Sugar: TRUE → `summary`, FALSE → `dev` |
| `COSTS` | bool | Per-statement `show_statistics` override (not valid
with `ANALYZE`) |

Postgres-only options (`BUFFERS`, `WAL`, `SETTINGS`, `GENERIC_PLAN`,
`MEMORY`) return a helpful unsupported-option error.

**Logical plan.** `Analyze` gains `analyze_level: Option<MetricType>`
and `analyze_categories: Option<ExplainAnalyzeCategories>`. `Explain`
gains `show_statistics: Option<bool>`. `None` means "fall back to
session config" — existing callers are unchanged.

**Physical planner.** `handle_analyze` and `handle_explain` prefer
statement-level overrides over session config before constructing
`AnalyzeExec` / `ExplainExec`. `AnalyzeExec` itself needs no change — it
already accepts the filters from #21160.

**Proto.** The new override fields round-trip through
`datafusion-proto`:

- `datafusion_common.proto` gains `MetricType`, `MetricCategory`, and an
`ExplainAnalyzeCategoriesNode` wrapper (`bool all` + `repeated
MetricCategory only`, mirroring the Rust enum's `All` / `Only(Vec<…>)`
variants).
- `AnalyzeNode` gains `optional MetricType analyze_level` and `optional
ExplainAnalyzeCategoriesNode analyze_categories`; `ExplainNode` gains
`optional bool show_statistics`.
- `ExplainOption` is extended with `analyze_level` /
`analyze_categories` setters so the proto decode arms construct
`LogicalPlan::Analyze` / `LogicalPlan::Explain` through the same
`LogicalPlanBuilder::explain_option_format` path as the SQL planner.

## Are these changes tested?

Yes:

- **Unit tests** in `datafusion/sql/src/parser.rs` cover legacy keyword
form on PostgreSQL dialect, each option form (`bare`, `= val`, `ON/OFF`,
quoted), unknown-option errors, dialect gating (the parenthesized form
is rejected under a dialect that doesn't enable it), and the error path
for unsupported Postgres-only options.
- **Integration tests** in
`datafusion/core/tests/sql/explain_analyze.rs` —
`explain_analyze_paren_metrics_filtering`,
`explain_analyze_paren_level_overrides_session_config`,
`explain_analyze_paren_metrics_overrides_session_config`,
`explain_paren_buffers_rejected`.
- **sqllogictest** fixtures in
`datafusion/sqllogictest/test_files/explain.slt` covering the
parenthesized form, round-trip with the legacy form, and each error
path.
- **Proto round-trip tests** in
`datafusion/proto/tests/cases/roundtrip_logical_plan.rs` —
`roundtrip_explain_show_statistics_override`,
`roundtrip_analyze_level_override`,
`roundtrip_analyze_categories_override` — cover each field set and
unset, including `All`, `Only(vec![])` (plan-only), and a fully
populated `Only` list.

Ran `cargo fmt --all` and `cargo clippy --all-targets --all-features --
-D warnings` (clean). Two pre-existing test failures on `main`
(`test_display_pg_json` snapshot and a `pgjson` SLT case at
`explain.slt:642`) are unrelated to this change — verified by running
them against a clean checkout of the same base commit.

## Are there any user-facing changes?

Yes — new syntax. User-facing docs updated at
`docs/source/user-guide/explain-usage.md` with a new section describing
the option list and the dialect gate. No breaking changes: the legacy
keyword form continues to work exactly as before.

+| `COSTS`   | boolean           | Include statistics in plain `EXPLAIN` output (equivalent to `SET datafusion.explain.show_statistics`). Not valid with `ANALYZE`.     |
+
+Boolean arguments can be written bare (`ANALYZE` → `true`), as `TRUE`/`FALSE`,
+`ON`/`OFF`, or `0`/`1`.
+
+The statement-level options take precedence over session config, so you can leave
+the session defaults alone and override just for the current query:
+
+```sql
+EXPLAIN (ANALYZE, LEVEL dev, METRICS 'rows,bytes') SELECT ...;
+```
+
+Postgres options that DataFusion does not model (`BUFFERS`, `WAL`, `SETTINGS`,
+`GENERIC_PLAN`, `MEMORY`) return a clear error rather than being silently
+accepted — use `METRICS` to filter what appears in the output.
+

Subject: [PATCH 095/878] Migrate UnKnownColumn proto hooks (#22464)

## Which issue does this PR close?

- Closes #22420.

## Rationale for this change

This issue is part of the migration to the new proto hooks ( ry_to_proto
/ ry_from_proto). UnKnownColumn was still handled in the legacy match
arms, so this ports it to the hook-based path for consistency with other
migrated expressions (e.g. Column, BinaryExpr).

## What changes are included in this PR?

- Add ry_to_proto / ry_from_proto implementations for UnKnownColumn in
physical-expr.
- Remove the legacy UnKnownColumn match arms in datafusion/proto
physical plan conversion.

## Are these changes tested?

- cargo test -p datafusion-proto --lib

## Are there any user-facing changes?

No user-facing changes.

Subject: [PATCH 096/878] refactor: Port IsNotNullExpr proto serialization
 hooks (#22532)

## Which issue does this PR close?

- Closes #22424.

## Rationale for this change

This is part of #22418, which migrates built-in `PhysicalExpr`
implementations away from the central protobuf serialization /
deserialization chains.

`IsNotNullExpr` can now own its protobuf serialization through
`PhysicalExpr::try_to_proto` and its deserialization through
`IsNotNullExpr::try_from_proto`, matching the pattern introduced for
`Column` and `BinaryExpr`.

## What changes are included in this PR?

- Adds `PhysicalExpr::try_to_proto` support for `IsNotNullExpr`.
- Adds `IsNotNullExpr::try_from_proto`.
- Wires `IsNotNullExpr` deserialization in `from_proto.rs` through the
new hook.
- Removes the old `IsNotNullExpr` serialization branch from the central
`to_proto.rs` downcast chain.
- Adds direct proto hook tests for:
  - successful `IsNotNullExpr` roundtrip
  - wrong protobuf expression variant
  - missing required child expression

## Are these changes tested?

Yes.

```bash
cargo fmt --all --check
git diff --check
cargo test -p datafusion-physical-expr --features proto is_not_null_
cargo clippy -p datafusion-proto --tests -- -D warnings
cargo test -p datafusion-proto --test proto_integration
```

## Are there any user-facing changes?
No.

Subject: [PATCH 097/878] Optimize Parquet metadata row-group level statistics
 collection (#22462)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #.

## Rationale for this change

The current stats aggregation does a bunch of unnecessary work, this PR
tries to do the minimal amount of work at every step.

## What changes are included in this PR?

In addition to splitting up the summarization logic into some clearer
functions and a reusable function for min/max, I've tried to do the
minimal amount of work at each step:
1. Only allocate boolean masks if there's a mix of exact/inexact stats
between row groups.
2. No need to allocate an Arrow array for null count.
3. No need to re-calculate the parquet column index - its already in
`stats_converter`, as far as I can tell its exactly the same code path.
4. No need to recalculate the number of rows - we already know it.

I've also included a benchmark, the effect on my laptop is:
```

                        time:   [2.9945 ms 3.0313 ms 3.0487 ms]

## Are these changes tested?

Existing tests and few additional small unit tests.

## Are there any user-facing changes?

None

-->

Part of  https://github.com/apache/datafusion/issues/21172

## Rationale for this change

`HigherOrderUDF` was the only UDF kind defined as a trait that callers
used directly via `Arc<dyn HigherOrderUDF>`. The other UDFs:
`ScalarUDF`, `AggregateUDF`, `WindowUDF` — are concrete structs that
wrap their respective `*Impl trait`, which makes inherent methods like
`with_aliases` ergonomic to call on the function object. With the
trait-only setup, adding aliases to an existing higher-order function
required an extension trait import or a free helper function.

This PR brings higher order functions in line with the other UDFs so the
same `with_aliases` pattern works.

## What changes are included in this PR?

- Rename the `HigherOrderUDF` trait to `HigherOrderUDFImpl`, matching
`ScalarUDFImpl`/`AggregateUDFImpl`.
Add a concrete `HigherOrderUDF` struct wrapping `Arc<dyn
HigherOrderUDFImpl>`, with the same shape as `ScalarUDF`: new_from_impl,
new_from_shared_impl, inner, with_aliases, From<F: HigherOrderUDFImpl>,
and delegate methods for every trait method.
`with_aliases` is backed by a private `AliasedHigherOrderUDFImpl`
decorator (same pattern as `AliasedScalarUDFImpl`).
- Update `Expr::HigherOrderFunction`, `FunctionRegistry`, the
`create_higher_order! `singleton macro, and all consumer files ( across
several crates) to use `Arc<HigherOrderUDF>` instead of `Arc<dyn
HigherOrderUDF>`.
Existing impls (`ArrayFilter`, `ArrayTransform`, `ArrayAnyMatch`) now
implement `HigherOrderUDFImpl`; their public constructors continue to
return `Arc<HigherOrderUDF>` so external call sites need no changes.

Callers can now write:

`array_filter_higher_order_function().with_aliases(["filter"])
`

exactly like the existing scalar pattern:

`make_array_udf().as_ref().clone().with_aliases(["array_construct"])
`

## Are these changes tested?

Covered by existing tests

## Are there any user-facing changes?

Yes, any code referring to `Arc<dyn HigherOrderUDF>` needs to become
`Arc<HigherOrderUDF>`, and any code that wrote `impl HigherOrderUDF for
MyHOF` needs to write i`mpl HigherOrderUDFImpl for MyType`. Constructing
a HigherOrderUDF from an impl is HigherOrderUDF::new_from_impl(my_impl)
(or my_impl.into()).

Subject: [PATCH 099/878] fix: guard repeat array length overflow (#22293)

## Which issue does this PR close?

- Closes #22217.

## Rationale for this change

The array execution path for `repeat(string, count)` calculated
`string.len() * count` before checking the configured string-size limit.
For very large counts, that multiplication can overflow and panic
instead of returning the same string-size overflow error used by the
scalar path.

## What changes are included in this PR?

- Adds checked count conversion and repeated-length calculation helpers.
- Uses checked multiplication and checked total-capacity accumulation in
the array path.
- Adds Rust and sqllogictest coverage for the one-row columnar
reproducer from the issue.

## Are these changes tested?

- `cargo fmt --all`
- `TMPDIR=/home/sean/Projects/datafusion-repeat-overflow/target/tmp
cargo test -p datafusion-functions
string::repeat::tests::test_repeat_string_array_overflow -- --nocapture`
- `TMPDIR=/home/sean/Projects/datafusion-repeat-overflow/target/tmp
cargo test --profile=ci --test sqllogictests --
string/string_literal.slt`
- `TMPDIR=/home/sean/Projects/datafusion-repeat-overflow/target/tmp
cargo clippy --all-targets --all-features -- -D warnings`
- `git diff --check`

## Are there any user-facing changes?

Invalid oversized `repeat` results in the columnar path now return a
normal DataFusion string-size overflow error instead of panicking.

Subject: [PATCH 100/878] refactor: Port IsNullExpr proto serialization hooks
 (#22509)

## Which issue does this PR close?

- Closes #22423.

## Rationale for this change

This is part of #22418, which migrates built-in `PhysicalExpr`
implementations away from the central protobuf serialization /
deserialization chains.

`IsNullExpr` can now own its protobuf serialization through
`PhysicalExpr::try_to_proto` and its deserialization through
`IsNullExpr::try_from_proto`, matching the pattern introduced for
`Column` and `BinaryExpr`.

## What changes are included in this PR?

- Adds `PhysicalExpr::try_to_proto` support for `IsNullExpr`.
- Adds `IsNullExpr::try_from_proto`.
- Wires `IsNullExpr` deserialization in `from_proto.rs` through the new
hook.
- Removes the old `IsNullExpr` serialization branch from the central
`to_proto.rs` downcast chain.
- Adds direct proto hook tests for:
  - successful `IsNullExpr` roundtrip
  - wrong protobuf expression variant
  - missing required child expression

## Are these changes tested?

Yes.

I ran:

```bash
cargo test -p datafusion-physical-expr --features proto is_null_
cargo clippy -p datafusion-physical-expr --features proto --tests -- -D warnings
cargo test -p datafusion-proto --test proto_integration
cargo clippy --all-targets --all-features -- -D warnings
cargo fmt --all

Subject: [PATCH 102/878] fix: widen `power(decimal, float)` to Float64, fix
 bugs (#22482)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22472.

## Rationale for this change

This PR makes several improvements to the `power` UDF:

1. Previously, `power(decimal, float)` returned `decimal`, with the same
precision as the first argument. This could result in silently
truncating the result value and is inconsistent with the behavior of
Postgres and DuckDB; for example, `power(2.5::decimal(2, 1), 4.0)`
returned `39` instead of `39.0625`. This PR changes `power(decimal,
float)` to return a `Float64` instead by removing the `power(decimal,
float)` path entirely: type coercion will result in taking the `(float,
float)` path.

2. `simplify` for `power` could sometimes have resulted in mismatches
between the declared return type of the function and the simplified
expression. Change this to insert casts instead.

3. Previously, `power(decimal, int-array)` converted its inputs to
`Float64`, on the argument that this improved performance. Empirically,
this does not seem to be the case (see benchmarks below), although
perhaps it was true with older version of Arrow. Perhaps more
importantly, converting exact numeric types to floating point is
undesirable because it loses precision. The behavior here was also
inconsistent with the behavior for `power(decimal, int-scalar)`.

Benchmarks (Arm64):

## What changes are included in this PR?

* Implement fixes/improvements described above.
* Various refactoring and code cleanup
* Add new benchmark
* Update SLT tests

## Are these changes tested?

Yes; new tests added.

## Are there any user-facing changes?

Yes; this commit changes the behavior of `power` with a decimal base. In
most cases this is a clear improvement; one slight regression is that
the `decimal` code path for `power` is more likely to needlessly
overflow (#22480); I will fix that in a followup PR.

Subject: [PATCH 103/878] feat: add SparkPow UDF returning Infinity for pow(0,
 negative) (#22605)

## Which issue does this PR close?

Closes #22598

## Rationale for this change

In Apache Spark, the `pow(base, exp)` function follows IEEE 754
semantics where raising `0` (or `-0.0`) to a negative exponent yields
positive `Infinity`.

Currently, DataFusion's default core `PowerFunc` mimics PostgreSQL
behavior, throwing an explicit error (`"zero raised to a negative power
is undefined"`). To support standard Spark compatibility without
breaking core DataFusion expectations, this PR introduces a specialized
`SparkPow` UDF inside the `datafusion-spark` crate.

## What changes are included in this PR?

This PR introduces the following changes within the `datafusion-spark`
integration crate:
* **Added `SparkPow` UDF**
(`datafusion/spark/src/function/math/pow.rs`): Overrides the `Float64`
execution path to evaluate `base == 0.0 && exp < 0.0` as `f64::INFINITY`
(safely catching both `0.0` and `-0.0` due to IEEE 754 equality rules).
* **Decimal Delegation**: Preserves correctness by delegating non-float
types (like decimals) back to the standard `PowerFunc`, as decimals
cannot represent infinity.
* **Function Registration**
(`datafusion/spark/src/function/math/mod.rs`): Registers the new `pow`
function and establishes `power` as a valid alias.
* **SQL Integration Tests**
(`datafusion/sqllogictest/test_files/spark/math/pow.slt`): Updates and
adds test coverage ensuring `pow(0, -1)`, `power(0, -1)`, and `pow(0.0,
-1.0)` successfully return `Infinity`.

## Are these changes tested?

Yes, the changes are covered via both unit and integration tests:
1. **Unit Tests**: Added `test_spark_pow_zero_negative_returns_infinity`
and `test_spark_pow_normal_cases` within `pow.rs` to validate the core
scalar execution logic.
2. **Integration Tests**: Extended
`datafusion/sqllogictest/test_files/spark/math/pow.slt` to verify the
end-to-end SQL evaluation behavior.

## Are there any user-facing changes?

Yes, but only for users utilizing the `datafusion-spark` compatibility
features. When the Spark dialect/crate is active, evaluating `pow(0,
<negative>)` will now return `Infinity` instead of throwing an
evaluation error. Core DataFusion behavior remains completely unchanged.

Subject: [PATCH 104/878] Fix TopK DISTINCT aggregation preserving NULLs
 (#22571)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22554.

## Rationale for this change

TopK aggregation dropped NULL group keys for ordered DISTINCT queries.

For example, `SELECT DISTINCT v FROM t ORDER BY v ASC NULLS FIRST LIMIT
1` could return an empty string instead of NULL when TopK aggregation
was enabled.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

This PR preserves NULL group keys for DISTINCT TopK aggregation by
tracking whether a NULL group key was seen separately from the heap.

The heap still only stores non-NULL values. This avoids making the TopK
heap implementations handle NULL values directly.

The stream also now marks itself done after emitting, so NULL-only
DISTINCT results are emitted once and do not repeat.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No API Change

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 105/878] Add range partitioning sqllogictest fixture (#22607)

## Which issue does this PR close?

- Part of #22397.
- Discussion: #21992.

## Rationale for this change

This adds a focused sqllogictest fixture for source-provided `Range`
partitioning before changing optimizer behavior. It follows the
direction discussed in #21992 and gives later planning PRs stable
baselines for current behavior.

## What changes are included in this PR?

- Registers a `range_partitioned` test table for
`range_partitioning.slt`.
- Adds a sqllogictest-only source wrapper that reports `Range`
partitioning when `range_key` is projected, and `UnknownPartitioning`
when it is not.
- Adds baselines for grouping on the range key, grouping on a non-range
key, joining on the range key, and `UNION ALL` over range-partitioned
inputs.

## Are these changes tested?

Yes.

- `cargo fmt --all`
- `cargo test -p datafusion-sqllogictest --test sqllogictests
range_partitioning`
- `cargo clippy --all-targets --all-features -- -D warnings`

## Are there any user-facing changes?

No. This is test-only infrastructure and sqllogictest coverage.

Subject: [PATCH 106/878] fix(physical-plan): make HashJoinExec dynamic filter
 pushdown idempotent (#22523)

## Which issue does this PR close?

Related to https://github.com/apache/datafusion-ballista/issues/1359

## Rationale

Ballista's Adaptive Query Execution (AQE) planner re-invokes
DataFusion's full `PhysicalOptimizer` chain after every completed stage.
`FilterPushdown::new_post_optimization()` is not idempotent on plans
containing `HashJoinExec`.

In the `Post` phase, `HashJoinExec::gather_filters_for_pushdown`
unconditionally creates a new `DynamicFilterPhysicalExpr` and installs
it on the probe-side child via `with_self_filter`. After pass 1 the join
already carries a `dynamic_filter: Some(...)`, and the shared
`Arc<DynamicFilterPhysicalExpr>` is already wired into the probe-side
scan's predicate. On pass 2 a *second* dynamic filter is created and
ANDed onto the existing predicate, producing `DynamicFilter AND
DynamicFilter`. Each subsequent pass adds another duplicate, compounding
indefinitely in AQE replan loops.

## What changes are included in this PR?

- **Guard in `HashJoinExec::gather_filters_for_pushdown`**: skip
dynamic-filter creation when `self.dynamic_filter.is_some()`, meaning a
previous pass already installed one. The existing `Arc` remains valid
and correctly wired into the probe-side scan.
- **Comment** explaining why the guard is needed (AQE replan context).
- **Test** `post_phase_is_idempotent_on_hash_join` in
`tests/physical_optimizer/filter_pushdown.rs`: builds a `HashJoinExec`,
runs `FilterPushdown::new_post_optimization()` twice, and asserts
structural equality via `get_plan_string`.

## Are these changes tested?

Yes. The new test fails without the fix (plan strings diverge due to
duplicated dynamic filter predicates) and passes with it.

## Are there any user-facing changes?

No. Dynamic filter pushdown is an internal optimization; the idempotence
guard only affects re-optimization scenarios (AQE).

Subject: [PATCH 107/878] feat: add pgjson format support for EXPLAIN ANALYZE
 (#21767)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #.

## Rationale for this change

DataFusion already emits PostgreSQL JSON (pgjson) for logical plans via
`EXPLAIN (FORMAT pgjson) ...`. This PR extends that support to `EXPLAIN
ANALYZE` so the physical plan, along with live execution metrics, can be
fed into pgjson visualizers such as
[Dalibo](https://explain.dalibo.com/) and PEV2.

Today, `EXPLAIN ANALYZE FORMAT pgjson` is explicitly rejected in the
planner with `"EXPLAIN ANALYZE with FORMAT is not supported"`. With this
PR the restriction is lifted for pgjson.

## What changes are included in this PR?

- Add a `format: ExplainFormat` field to the logical `Analyze` node and
the physical `AnalyzeExec` operator, threaded through SQL parsing,
logical planning, and physical planning.
- Accept `EXPLAIN ANALYZE FORMAT pgjson <stmt>`. `Tree` and `Graphviz`
with `ANALYZE` still error with a clear message (out of scope for this
PR).
- Add `DisplayableExecutionPlan::pgjson()` and a new
`PgJsonExecutionPlanVisitor` that mirror the logical-plan
`PgJsonVisitor`. Per-node output includes:
  - `Node Type` — `ExecutionPlan::name()`
  - `Details` — the one-line `DisplayAs::Default` rendering
- `Actual Rows` / `Actual Total Time` — PG-canonical metric keys
populated from `output_rows` / `elapsed_compute` (emitted as float
milliseconds; note DataFusion records compute time, not wall time)
  - `Extras` — remaining DataFusion metrics keyed by their native name
  - `Plans` — child nodes
- Add an optional `set_summary()` builder so `AnalyzeExec` can attach
`Total Rows` and `Duration` at the root in verbose mode.
- Honor existing `analyze_level` / `analyze_categories` config exactly
as `indent()` does.
- Update the `EXPLAIN` user-guide docs
(`docs/source/user-guide/sql/explain.md` and `explain-usage.md`) to
document pgjson support under `ANALYZE` and lead with the Postgres-style
option-list spelling.

### Composes with the `EXPLAIN (...)` option list (#21768)

This builds on the now-merged Postgres-style option list (#21768).
Because both the keyword form and the parenthesized option list parse
into a single `ExplainStatementOptions` that is threaded through
`explain_to_plan`, pgjson works with **both** spellings, and the
`METRICS` / `LEVEL` knobs from #21768 compose with it in one statement:

```sql
EXPLAIN (ANALYZE, FORMAT pgjson) SELECT count(*) FROM t;
EXPLAIN (ANALYZE, FORMAT pgjson, METRICS 'rows', LEVEL summary) SELECT count(*) FROM t;
```

The parenthesized form is the idiomatic spelling for pgjson workflows
since it mirrors Postgres's `EXPLAIN (ANALYZE, FORMAT json)` — exactly
what visualizers like Dalibo / PEV2 document. (Note: `ANALYZE` must go
*inside* the parens; a bare `EXPLAIN ANALYZE (FORMAT pgjson)` is
invalid, as it is in Postgres.)

## Are these changes tested?

- Unit tests in `datafusion/physical-plan/src/display.rs`:
  - `pgjson_renders_plan_without_metrics`
  - `pgjson_includes_summary_when_set`
  - `pgjson_snapshot_of_sample_plan` (insta snapshot)
- sqllogictest coverage in
`datafusion/sqllogictest/test_files/explain_analyze.slt`:
- Structural golden for `EXPLAIN (ANALYZE, FORMAT PGJSON, METRICS
'none')` (option-list form)
- `EXPLAIN (ANALYZE, FORMAT PGJSON, METRICS 'rows')` showing `Actual
Rows` surfacing
  - Keyword form `EXPLAIN ANALYZE FORMAT pgjson` still works
- Negative tests for `EXPLAIN ANALYZE FORMAT tree` and `EXPLAIN ANALYZE
FORMAT graphviz`
- `cargo clippy --all-targets --all-features -- -D warnings` clean on
the touched crates; `cargo fmt --all` clean.

## Are there any user-facing changes?

Yes — `EXPLAIN ANALYZE` now accepts the `pgjson` format, in either
spelling:

```sql
-- Postgres-style option list (idiomatic; composes with METRICS / LEVEL)
EXPLAIN (ANALYZE, FORMAT pgjson) SELECT count(*) FROM t;

-- legacy keyword form
EXPLAIN ANALYZE FORMAT pgjson SELECT count(*) FROM t;
```

No existing behavior changes: the default (`EXPLAIN ANALYZE ...` with no
`FORMAT`) still emits the indent-format plan with metrics, and `EXPLAIN
(FORMAT pgjson) ...` on the logical plan is unchanged.

Subject: [PATCH 108/878] minor: Improve error message for invalid column
 expression in `SELECT` statement (#22486)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
User friendly 'did you mean' error message is missing for some cases,
this PR fixes it.

### Demo in `datafusion-cli`
```
-- Before
> create external table hits
stored as parquet
location '/Users/yongting/Code/datafusion/benchmarks/data/hits_partitioned';
0 row(s) fetched.
Elapsed 0.056 seconds.

> select url+1 from hits;
Schema error: No field named url. Valid fields are hits."WatchID", hits."JavaEnable", hits."Title", hits."GoodEvent", hits."EventTime", hits."EventDate", hits."CounterID", hits."ClientIP", hits."RegionID", hits."UserID", hits."CounterClass",
...
```

```
-- PR
> select url from hits;
Schema error: No field named url. Did you mean 'hits."URL"'?
Column names are case sensitive. You can use double quotes to refer to the hits."URL" column or set the datafusion.sql_parser.enable_ident_normalization configuration.
Valid fields are hits."WatchID", hits."JavaEnable", hits."Title", hits."GoodEvent", hits."EventTime", hits."EventDate", hits."CounterID", hits."ClientIP", hits."RegionID", hits."UserID", hits."CounterClass", hits."OS", hits."UserAgent", hits."URL", hits."Referer", hits."IsRefresh", hits."RefererCategoryID", hits."RefererRegionID", hits."URLCategoryID", hits."URLRegionID",
...
```

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 109/878] fix(physical-optimizer): make OutputRequirements
 idempotent (#22522)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Related to https://github.com/apache/datafusion-ballista/issues/1359

## Rationale

Ballista's Adaptive Query Execution (AQE) planner re-invokes
DataFusion's full `PhysicalOptimizer` chain after every completed stage
(`AdaptivePlanner::replan_stages`). Rules that are not idempotent
(`rule(rule(x)) != rule(x)`) stack execution-plan nodes on each pass.

`OutputRequirements::new_add_mode()` wraps the plan root with
`OutputRequirementExec` to preserve global ordering/distribution
requirements. On a second pass the wrapper's `maintains_input_order() ==
[true]` and `required_input_ordering() == [None]` cause
`require_top_ordering_helper` to recurse through it and produce a
*second* wrapper, yielding
`OutputRequirementExec(OutputRequirementExec(...))`. Each AQE replan
adds another layer.

## What changes are included in this PR?

- **Guard in `require_top_ordering()`**: if the plan root is already an
`OutputRequirementExec`, return it unchanged. This makes the rule
idempotent with zero overhead for single-pass use.
- **Doc-comment update** on `new_add_mode()` and
`require_top_ordering()` documenting the idempotence guarantee.
- **Two tests** in `tests/physical_optimizer/output_requirements.rs`:
- `add_mode_is_idempotent_on_bare_scan` — bare `ParquetExec` (exercises
`is_changed = false` path).
- `add_mode_is_idempotent_on_sorted_plan` — `SortExec → ParquetExec`
(exercises `is_changed = true` path).

## Are these changes tested?

Yes. Two new tests run the rule twice on distinct fixtures and assert
structural equality via `get_plan_string`. Both fail without the fix
(double-wrapped `OutputRequirementExec`) and pass with it.

## Are there any user-facing changes?

No. `OutputRequirementExec` is an internal ancillary node stripped
before execution; the idempotence guard only affects re-optimization
scenarios (AQE).

Subject: [PATCH 110/878] fix: reborrow metadata values when intersecting union
 metadata (#22491)

## Which issue does this PR close?

- Closes #22488.

## Rationale for this change

`intersect_metadata_for_union` compares values retained by
`HashMap::retain` with values from another metadata map. The retained
value is passed as `&mut String`, which can make `Option` equality
ambiguous for downstream crates when additional blanket `PartialEq`
implementations are in scope.

Reborrowing the retained value as `&String` keeps the comparison type
explicit without changing behavior.

## What changes are included in this PR?

The metadata retain predicate now compares `metadata.get(k)` with
`Some(&*v)` instead of `Some(v)`.

## Are these changes tested?

Yes.

- `cargo test -p datafusion-expr intersect_metadata_tests`
- `cargo fmt --all -- --check`
- `git diff --check`

## Are there any user-facing changes?

No runtime behavior change. This avoids a downstream compilation failure
in the reported dependency configuration.

Subject: [PATCH 111/878] fix(array_agg): reverse ordering_values in state()
 when accumulator is reversed (#22597)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

No existing issue. Discovered while investigating incorrect results from
`ARRAY_AGG(x ORDER BY y DESC)` in a multi-partition query.

## Rationale for this change

### Bug description

When multiple `ARRAY_AGG` expressions with conflicting `ORDER BY`
directions (ASC and DESC) appear in the same query, results for the DESC
variant are silently wrong.

### How the optimizer creates the bug path

The bug is triggered deterministically by a well-defined optimizer
pipeline. Take this query:

```sql
SELECT
  ARRAY_AGG(c1 ORDER BY c1 ASC),
  ARRAY_AGG(c1 ORDER BY c1 DESC)
FROM t
```

**Step 1 — `get_finer_aggregate_exprs_requirement` (runs at
`AggregateExec` construction)**

This function iterates the aggregate expressions to find a single common
ordering requirement that the input sort can satisfy:

1. Takes the first aggregate's requirement → `common = [c1 ASC]`
2. Second aggregate needs `[c1 DESC]` — conflicts with `[c1 ASC]`
3. Checks reverse of second: `reverse(DESC) = ASC` → `[c1 ASC]`
satisfies it
4. **Mutates `aggr_expr[1]` in-place**: flips `ARRAY_AGG(c1 DESC)` →
`ARRAY_AGG(c1 ASC, is_reversed=true)`
5. `AggregateExec::required_input_ordering` is set to `[c1 ASC]` (soft
requirement)

The DESC aggregate is already reversed to ASC before any other rule
runs.

**Step 2 — `EnsureRequirements` optimizer**

Sees `required_input_ordering = [c1 ASC]` → inserts `SortExec [c1 ASC]`
before the partial aggregate.

**Step 3 — `OptimizeAggregateOrder` optimizer**

Runs on the partial aggregate (input mode = Raw). Input is now sorted
`[c1 ASC]`. For each aggregate:

- `ARRAY_AGG(c1 ASC)`: direct match → `is_input_pre_ordered=true,
reverse=false` ✓
- `ARRAY_AGG(c1 ASC, is_reversed=true)` (already mutated): direct match
→ `is_input_pre_ordered=true, reverse=true` ← **bug path**

The DESC accumulator ends up with `ordering_req=[c1 ASC]`,
`is_input_pre_ordered=true`, `reverse=true`.

### Root cause

In `OrderSensitiveArrayAggAccumulator::state()`:

```rust
let mut result = vec![self.evaluate()?];   // reverses values list → DESC order ✓
result.push(self.evaluate_orderings()?);    // ordering keys stay in original ASC order ✗
```

`evaluate()` reverses `self.values` (ASC input → DESC output), but
`evaluate_orderings()` always iterated `self.ordering_values` forward.
The partial state emits a **mismatched** pair: values in DESC order,
ordering keys in ASC order.

The final accumulator's `merge_batch` uses `merge_ordered_arrays` with
the ordering keys to decide k-way merge priority. Because the keys are
paired with the wrong values, the merge produces the wrong order —
silently, no error or panic.

Note: if DESC is listed first and ASC second, the roles are swapped —
the ASC aggregate gets reversed and its result is wrong instead. The bug
always hits whichever aggregate `get_finer_aggregate_exprs_requirement`
reverses.

## What changes are included in this PR?

Single change in `evaluate_orderings()` inside
`OrderSensitiveArrayAggAccumulator`:

```rust
// Before
let column_values = self.ordering_values.iter().map(|x| x[i].clone());

// After
let column_values: Box<dyn Iterator<Item = ScalarValue>> = if self.reverse {
    Box::new(self.ordering_values.iter().rev().map(|x| x[i].clone()))
} else {
    Box::new(self.ordering_values.iter().map(|x| x[i].clone()))
};
```

When `reverse=true`, ordering keys are iterated in reverse to match the
reversed values emitted by `evaluate()`, so `merge_batch` receives
correctly paired `(value, ordering_key)` entries.

## Are these changes tested?

**Unit test** — `desc_order_partial_final_merge_correct` in
`array_agg.rs` directly exercises the partial→final merge path with a
reversed accumulator (`is_input_pre_ordered=true, reverse=true`). Before
fix: `[3, 4, 5, 0, 1, 2]`. After fix: `[5, 4, 3, 2, 1, 0]`.

**SQL logic test** — regression test in `aggregate.slt` runs the exact
bug-triggering query against a real 10-row table:

```sql
SELECT array_agg(c1 ORDER BY c1), array_agg(c1 ORDER BY c1 DESC) FROM agg_order;
```

The EXPLAIN confirms `SortExec [c1 ASC]` + `Partial`/`Final` stages (the
optimizer path that triggers the bug). The result assertion catches the
wrong output:

```
-- without fix (wrong):
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]  [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

-- with fix (correct):
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]  [10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
```

## Are there any user-facing changes?

Yes — `ARRAY_AGG(x ORDER BY y DESC)` now returns correct results when
the query uses multi-partition execution and the optimizer reverses the
partial accumulator.

Subject: [PATCH 112/878] Gate new ScalarSubqueryExec node behind session
 property (#22530)

## Which issue does this PR close?

Related to discussion on #21240 and
https://github.com/apache/datafusion/issues/21080#issuecomment-4543527331.


PR #21240 introduced `ScalarSubqueryExec` / `ScalarSubqueryExpr` to
execute uncorrelated scalar subqueries during physical execution. The
two communicate via shared in process state (a `slot` in
`ExecutionProps`), which breaks distributed execution that may split
execution across a network boundary between the producer
(`ScalarSubqueryExec`) and the consumer expression
(`ScalarSubqueryExpr`). See more details on this explanation in
[datafusion-contrib/datafusion-distributed#460](https://github.com/datafusion-contrib/datafusion-distributed/issues/460)

## What changes are included in this PR?

Adds a new optimizer config option
`datafusion.optimizer.enable_physical_uncorrelated_scalar_subquery`
(default true, preserving the current behavior). When true (default),
behavior is unchanged from current main; when false, all scalar
subqueries are rewritten to left joins by `ScalarSubqueryToJoin` and
`ScalarSubqueryExec` is never constructed (which was the previous
behavior).

## Are these changes tested?

Yes all tests pass and added
`uncorrelated_scalar_subquery_rewritten_when_flag_off` to test the
negative case.

## Are there any user-facing changes?

Yes, a new config option
`datafusion.optimizer.physical_uncorrelated_scalar_subquery` (this just
changes the way the query is executed but not the results)

For example, for a query such as `SELECT * FROM t ORDER BY timestamp DESC LIMIT 10`, the optimizer will attempt to push down the current top 10 timestamps that the TopK operator references into the file scans. This means that if we already have 10 timestamps in the year 2025 any files that only have timestamps in the year 2024 can be skipped / pruned at various stages in the scan. The config will suppress `enable_join_dynamic_filter_pushdown`, `enable_topk_dynamic_filter_pushdown` & `enable_aggregate_dynamic_filter_pushdown` So if you disable `enable_topk_dynamic_filter_pushdown`, then enable `enable_dynamic_filter_pushdown`, the `enable_topk_dynamic_filter_pushdown` will be overridden.

+datafusion.optimizer.enable_physical_uncorrelated_scalar_subquery true When set to true, uncorrelated scalar subqueries are left in the logical plan and executed by `ScalarSubqueryExec` during physical execution. When set to false, all scalar subqueries (including uncorrelated ones) are rewritten to left joins by the `ScalarSubqueryToJoin` optimizer rule. Note disabling this option is not recommended. It restores pre <https://github.com/apache/datafusion/pull/21240> behavior, which silently produces incorrect results for multi-row subqueries and does not support scalar subqueries in ORDER BY / JOIN ON / aggregate-function arguments. This option is intended as a temporary escape hatch for distributed execution frameworks and is planned to be removed in a future DataFusion release.
 datafusion.optimizer.enable_piecewise_merge_join false When set to true, piecewise merge join is enabled. PiecewiseMergeJoin is currently experimental. Physical planner will opt for PiecewiseMergeJoin when there is only one range filter.

When enabled, attempts to push sort requirements down to data sources that can natively handle them (e.g., by reversing file/row group read order). Returns **inexact ordering**: Sort operator is kept for correctness, but optimized input enables early termination for TopK queries (ORDER BY ... LIMIT N), providing significant speedup. Memory: No additional overhead (only changes read order). Future: Will add option to detect perfectly sorted data and eliminate Sort completely. Default: true

For example, for a query such as `SELECT * FROM t ORDER BY timestamp DESC LIMIT 10`, the optimizer will attempt to push down the current top 10 timestamps that the TopK operator references into the file scans. This means that if we already have 10 timestamps in the year 2025 any files that only have timestamps in the year 2024 can be skipped / pruned at various stages in the scan. The config will suppress `enable_join_dynamic_filter_pushdown`, `enable_topk_dynamic_filter_pushdown` & `enable_aggregate_dynamic_filter_pushdown` So if you disable `enable_topk_dynamic_filter_pushdown`, then enable `enable_dynamic_filter_pushdown`, the `enable_topk_dynamic_filter_pushdown` will be overridden.                                                                                                                                                                                                                                                                                                                                                                                     |

Subject: [PATCH 113/878] fix: Correct join cardinality estimation for semi and
 anti joins with disjoint column ranges (#22674)

## Which issue does this PR close?

- Closes #22673

## Rationale for this change

`estimate_join_cardinality` for semi-joins checks if ANY of the columns
in the two join inputs are disjoint (comparing columns positionally); if
so, it claims the join will not return any rows. This is wrong, for two
reasons:

1. If two columns don't participate in the join key, they have no impact
on the cardinality of the join result
2. Comparing arbitrary columns positionally is not a sensible thing to
do in the first place

A similar issue exists for anti-joins, except we assume the anti-join
will return the entire join input in this case.

We should instead just check for disjoint ranges between the pairs of
columns that make up the join key.

## What changes are included in this PR?

* Fix `estimate_join_cardinality` behavior in the face of disjoint
column ranges that aren't join key columns
* Refactor `estimate_join_cardinality`, rename a variable for clarity
* Add unit test

## Are these changes tested?

Yes, new test added.

## Are there any user-facing changes?

Better plans / avoid buggy cardinality estimate.

Subject: [PATCH 114/878] chore: Add primary key constraints for TPC-H, TPC-DS
 (#22646)

## Which issue does this PR close?

- Closes #22595.

## Rationale for this change

The TPC-DS and TPC-H specifications define primary keys, but we
previously did not include those constraints when defining the TPC-DS
and TPC-H schemas. Including the constraints enables the query optimizer
to generate better plans (e.g., by leveraging FDs); it also makes the
benchmark setup closer to a realistic TPC-DS/H benchmark run.

To enable this, we need to fix `MemTable::load`: `MemTable` could be
constructed `with_constraints`, but those constraints were not attached
to the table returned by `MemTable::load`.

There is some duplication here: we define two copies of the primary keys
of both TPC-DS and TPC-H, because `benchmarks` and `test-utils` can't
easily share code. This could be improved but I'll defer that for now.

## What changes are included in this PR?

* Fix `MemTable::load` to include constraints on the newly loaded table
* Refactor `MemTable::load` to use `collect_partitioned`
* Add unit tests for new `MemTable::load` behavior
* Add TPC-DS and TPC-H primary keys to `benchmarks`
* Add TPC-DS and TPC-H primary keys to `test-utils`
* Add TPC-H primary keys to SLT schema definitions

## Are these changes tested?

New tests added for `MemTable::load` constraint behavior. SLT fixtures
updated for change in TPC schemas and plans.

## Are there any user-facing changes?

No.

Subject: [PATCH 115/878] fix: Projection stats Absent for columns referenced
 >1 time (#22679)

## Which issue does this PR close?

- Closes #22678.

## Rationale for this change

`ProjectionExprs::project_statistics` uses `std::mem::take` to move an
input column's `ColumnStatistics` into the output when given a direct
column reference. This means if the column is referenced again (either
directly or in a `CAST` expression), the statistics are `Absent`. The
simple fix is to just `clone` instead of `take`.

This pattern crops up in TPC-DS q54, which includes a CTE that projects
both `d_date_sk` and `CAST(d_date_sk AS Float64)`, but it's a more
general bug.

Subject: [PATCH 116/878] fix(substrait): plan nested projected window
 expressions (#22630)

## Which issue does this PR close?

- Closes #22629.

## Rationale for this change

The Substrait `ProjectRel` consumer only added a `WindowAggr` relation
when the root projected expression was a `WindowFunction`. A scalar
expression wrapping a valid window function therefore left the window
directly inside `Projection`, which cannot be physically planned.

Minimal reproducer represented by the added Substrait fixture:

```sql
SELECT 1 + count(*) OVER () FROM DATA;
```

Before this patch, the regression test produced this plan difference:

```diff
 Projection: Int64(1) + count(Int64(1)) ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING AS EXPR$0
-  WindowAggr: windowExpr=[[count(Int64(1)) ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING]]
-    TableScan: DATA
+  TableScan: DATA
```

This is the same class of failure that reaches physical planning as an
unsupported nested `WindowFunction` expression.

## What changes are included in this PR?

- Use existing `find_window_exprs(...)` recursion while consuming
Substrait `ProjectRel` expressions, retaining current `HashSet`
deduplication across projections.
- Add a minimal Substrait JSON fixture with a window function nested
inside an arithmetic scalar expression.
- Add a logical-plan snapshot plus execution regression, proving
`WindowAggr` is inserted and physically executable.

## Are these changes tested?

Pre-fix evidence:

- `cargo test -p datafusion-substrait --test substrait_integration
nested_window_function_in_expression -- --nocapture` failed because the
consumed plan omitted expected `WindowAggr` and put `Projection`
directly above `TableScan`.

Final validation on Apache `main` commit `d8c458828`:

- `cargo fmt --all -- --check`
- `cargo test -p datafusion-substrait` (49 unit passed, 200 integration
passed, 3 doctests passed; 6 existing ignored)
- `cargo check --all-targets -p datafusion-substrait`
- `cargo check --no-default-features -p datafusion-substrait`
- `cargo check --no-default-features -p datafusion-substrait
--features=physical`
- `cargo check --no-default-features -p datafusion-substrait
--features=protoc`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `./dev/rust_lint.sh`

## Are there any user-facing changes?

Substrait producers may now send projected expressions that contain
nested window functions; DataFusion consumes them into executable
logical plans instead of leaving unsupported window expressions in
projections.

Subject: [PATCH 117/878] fix: render binary columns as hex in
 DataFrame::describe() (#21728)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #21496.

## Rationale for this change

`DataFrame::describe()` is the standard way to get a statistical summary
of a DataFrame (count, null_count, mean, std, min, max, median per
column). Today it handles binary-like columns poorly:

- For `Binary`, an exclusion filter in `min`/`max` aggregations caused
both to be reported as `null`, losing useful information for columns
that hold hashes, UUIDs, fingerprints, or other content-addressed
identifiers.
- For `LargeBinary`, `BinaryView`, and `FixedSizeBinary`, the filter did
not apply, so `min`/`max` ran successfully but then the display step
tried to `cast(column, Utf8)`, which Arrow correctly rejects, producing
an `ArrowError::CastError` that bubbled up and failed the whole
`describe()` call.

The fix in this PR is aligned with what the issue proposes: stop
filtering `Binary` from the aggregations and render binary outputs as
lowercase hex (matching Arrow's default display of binary arrays).

## What changes are included in this PR?

- `datafusion/core/src/dataframe/mod.rs`:
- Drop `DataType::Binary` from the `min`/`max` exclusion filter (now
only `Boolean` is excluded, which is still meaningful for a statistical
summary).
- Add a dedicated display branch for `Binary`, `LargeBinary`,
`BinaryView`, and `FixedSizeBinary` that uses
`arrow::util::display::ArrayFormatter` with default options, which
renders bytes as lowercase hex.
  - Tidy a now-stale comment that referenced the previous binary filter.
- Drive-by: use the newly imported `FormatOptions` unqualified in
`DataFrame::to_string()` for consistency.

## Are these changes tested?

Yes, a new integration test `describe_binary_columns` in
`datafusion/core/tests/dataframe/describe.rs` builds an in-memory
`RecordBatch` with one column per binary-like type and asserts the full
`describe()` output via an inline `insta` snapshot. The test covers
non-null values and a null row per column, so it exercises both
`null_count` and the hex rendering path for `min`/`max`.

All existing `describe` tests continue to pass unchanged.

## Are there any user-facing changes?

Yes — this is a visible behavior change for `DataFrame::describe()`:

- Before: `min`/`max` on `Binary` columns were `null`; other binary-like
types caused a cast error.
- After: `min`/`max` on all binary-like types render as lowercase hex
strings (e.g. `"0001"`, `"ffee"`).

No public API changes.

Subject: [PATCH 118/878] test: cover regexp_like multiline flag (#22284)

## Which issue does this PR close?

- Relates to #22268.

## Rationale for this change

The issue documents a PostgreSQL compatibility expectation for
`regexp_like(E'a\nb', '^b', 'm')`: with the multiline flag, `^` should
match after a newline. Current `main` already returns the expected
result for the reported SQL, so this PR adds focused regression coverage
to keep that behavior from drifting.

## What changes are included in this PR?

This adds `regexp_like` tests for the multiline `m` flag in the SQL
logic test suite and in the Rust unit tests for the scalar,
array/scalar, and array/array execution paths. The adjacent no-flags SQL
case remains false, documenting that the new behavior is specifically
tied to `m`.

## Are these changes tested?

Yes:

- `cargo fmt --all --check`
- `git diff --check`
- `cargo test -p datafusion-functions --lib regexp_like`
- `cargo test -p datafusion-sqllogictest --test sqllogictests --
regexp_like`

## Are there any user-facing changes?

No. This is regression coverage for existing behavior.

Subject: [PATCH 119/878] feat: add array_subtract scalar function (#22556)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of [#21536](https://github.com/apache/datafusion/issues/21536)
(array_substract — first PR in the vector math series).

  ## Rationale for this change

  ## What changes are included in this PR?

  ## Are these changes tested?

  Yes, via SLT

  ## Are there any user-facing changes?

Yes — two new functions:

array_subtract(array1, array2) → List<Float64> / LargeList<Float64>
list_substract(...) alias

Both exposed via `expr_fn` and registered in
`all_default_nested_functions()`. Documented inline via `#[user_doc]`
  (description, syntax, SQL example, argument descriptions).

  No breaking API changes.

+### `array_subtract`
+
+Returns the element-wise difference of two numeric arrays of equal length, computed as `array1[i] - array2[i]` per position. NULL is propagated per element: if either input element at position `i` is NULL, the corresponding output element is NULL (positions are preserved). Returns NULL if either entire input array is NULL. Errors if the per-row lengths differ. Returns an empty array if both inputs are empty.

Subject: [PATCH 120/878] fix: wrong precision in a decimal256 log test
 (#22578)

## Which issue does this PR close?

## Rationale for this change

Spotted wrong usage of decimal precision in `test_log_decimal256_large`
- passed Decimal128 max precision instead of Decimal256. The test worked
fine.

## What changes are included in this PR?

- Test fixup
- Unhardcode the usage decimal precision in non-test code

## Are these changes tested?

- Tests passed

## Are there any user-facing changes?

Subject: [PATCH 121/878] fix: Avoid panic decoding invalid parquet writer
 version from proto (#22467)

## Which issue does this PR close?

- Closes #22468.

## Rationale for this change

Parquet file format proto decoding is exposed through a
`try_decode_file_format` API, but invalid `writer_version` values could
still panic because the Parquet options conversion used an infallible
`expect` while parsing the writer version.

This makes malformed or manually produced proto bytes abort the decode
path instead of returning a DataFusion error.

## What changes are included in this PR?

- Convert Parquet table options decoding in the file format codec to the
fallible `TryFromProto` path.
- Return the existing writer version validation error for invalid
non-empty proto values.
- Treat an empty proto `writer_version` as the default writer version
for compatibility with proto default values.
- Add regression coverage for invalid and empty writer version decoding.

## Are these changes tested?

- `cargo fmt --all`
- `cargo test -p datafusion-proto --lib try_decode_file_format
--features parquet`
- `cargo test -p datafusion-proto --lib --features parquet`
- `cargo clippy -p datafusion-proto --lib --features parquet -- -D
warnings`

## Are there any user-facing changes?

Invalid Parquet writer versions in serialized file format protos now
return an error instead of panicking during decode.

Subject: [PATCH 122/878] Guard insert placeholder zero (#22299)

## Which issue does this PR close?

- Fixes #22224.

## Rationale for this change

`EXPLAIN INSERT INTO t VALUES ($0)` currently panics while inferring
parameter types for INSERT VALUES. Other SQL paths already reject `$0`
as an invalid placeholder index, and the INSERT inference path should do
the same instead of subtracting one from zero.

## What changes are included in this PR?

- Adds a zero-index guard before INSERT VALUES placeholder numbers are
converted to parameter vector positions.
- Aligns the INSERT VALUES error with the existing invalid-placeholder
planning error.
- Adds a standalone SQL logic regression for `EXPLAIN INSERT INTO ...
VALUES ($0)`.

## Are these changes tested?

Yes.

- `cargo fmt --check --all`
- `cargo test -p datafusion-sqllogictest --test sqllogictests --
insert_values_placeholders`
- `cargo test -p datafusion-sql --test sql_integration
test_insert_schema_errors` -> 6 passed
- `git diff --check origin/main...HEAD`
- `git diff --cached --check`

## Are there any user-facing changes?

Yes. `INSERT ... VALUES ($0)` now returns a planning error instead of
panicking.

## Scope note

The change is limited to INSERT VALUES placeholder type inference and
the new regression coverage. I did not find any broader placeholder
semantics that needed to change.

Subject: [PATCH 123/878] added support for MapFromEntries (#21720)

## Which issue does this PR close?

Closes # (none: prerequisite for
https://github.com/apache/datafusion-comet/issues/2706; follow-up to
#17779 and #19274).

## Rationale for this change

Spark's default mapKeyDedupPolicy is EXCEPTION, raising
SparkRuntimeException with error class DUPLICATED_MAP_KEY on duplicate
map keys. The existing Spark map_from_entries / map_from_arrays UDFs
silently kept the last occurrence, forcing downstream engines like
datafusion-comet to fall back to Spark.

## What changes are included in this PR?

Duplicate map keys in Spark map_from_entries, map_from_arrays, and
str_to_map now raise [DUPLICATED_MAP_KEY] Duplicate map key {key} was
found, matching Spark's default behaviour and error class.

## Are these changes tested?

Yes, via sqllogictest assertions covering the new error across the
affected Spark map UDFs.

## Are there any user-facing changes?

Yes. Duplicate keys now raise [DUPLICATED_MAP_KEY] under the default
policy instead of silently collapsing to the last occurrence. No new
config keys, no API changes.

+### Spark map functions now reject duplicate keys by default
+
+The Spark-compatibility map-construction functions (`map_from_arrays`,
+`map_from_entries`, `str_to_map`) now raise `[DUPLICATED_MAP_KEY]` at runtime
+when constructing a map that contains duplicate keys. This matches the default
+of Spark's [`spark.sql.mapKeyDedupPolicy`](https://github.com/apache/spark/blob/v4.0.0/sql/catalyst/src/main/scala/org/apache/spark/sql/internal/SQLConf.scala#L4502-L4511).
+
+A new config option, `datafusion.spark.map_key_dedup_policy`, controls the
+behavior:
+
+- `EXCEPTION` (default): raise on any duplicate key.
+- `LAST_WIN`: keep the last occurrence of each duplicate key. The key stays at
+  its first-seen position with the value from its last occurrence (matching
+  Spark's `ArrayBasedMapBuilder`).
+
+**Who is affected:**
+
+- Queries calling `map_from_arrays` or `str_to_map` on data that contains
+  duplicate keys. Previously these functions either tolerated duplicates
+  silently or raised a non-configurable error.
+
+**Migration guide:**
+
+To restore lenient duplicate-key handling, set the policy to `LAST_WIN`:
+
+```sql
+SET datafusion.spark.map_key_dedup_policy = 'LAST_WIN';
+```
+
+See [PR #21720](https://github.com/apache/datafusion/pull/21720) for details.

Subject: [PATCH 124/878] chore: update Rust toolchain to 1.96.0 (#22611)

## Which issue does this PR close?

<!-- No tracking issue; routine toolchain maintenance. -->

- Closes #.

## Rationale for this change

Keeps the pinned Rust toolchain current. This bumps the toolchain used
to
compile the workspace and run CI jobs from `1.95.0` to `1.96.0`.

## What changes are included in this PR?

- `rust-toolchain.toml`: bump `channel` from `1.95.0` to `1.96.0`.
- `docs/source/contributor-guide/development_environment.md`: update the
`rustup component add --toolchain 1.96.0 rust-analyzer` example to
match.

The MSRV (`rust-version = "1.88.0"` in the workspace `Cargo.toml`) is
unchanged.

## Are these changes tested?

Covered by existing CI, which compiles and lints the workspace with the
pinned toolchain. `cargo clippy --all-targets --all-features -- -D
warnings`
was run locally against 1.96.0.

## Are there any user-facing changes?

No. This only affects the toolchain used by contributors and CI.

Subject: [PATCH 126/878] test: make push_down_filter_regression dynamic filter
 content deterministic (#22621) (#22643)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22621.

## Rationale for this change

`push_down_filter_regression.slt` (added in #22150) asserts the exact
`DynamicFilter` content rendered by `EXPLAIN ANALYZE` on the `agg_dyn_*`
fixtures. That content is **not** deterministic: the filter threshold
tightens
as each `AggregateExec(mode=Partial)` publishes its running `min`/`max`,
and the
`EXPLAIN ANALYZE` snapshot can be taken while the filter is still
converging.

For `agg_dyn_single`, `file_0` holds the global `min` (1) and `file_1` a
larger
partial `min` (3). If the snapshot lands after `file_1` publishes `3`
but before
`file_0` publishes `1`, the filter reads `a < 3` instead of the final `a
< 1` —
exactly the intermittent CI failure reported in #22621. The fixture's
comment
incorrectly claimed the filter *content* was deterministic and only the
pruning
*counts* raced.

## What changes are included in this PR?

Make the filter content independent of publish order by giving **every
file the
same per-file min/max**, so any snapshot equals the fully converged
filter:

- `agg_dyn_single` — both files `(1), (8)` → each file `min=1, max=8`.
- `agg_dyn_two_col` — each file `min(a)=1, max(b)=9`.
- `agg_dyn_mixed` — each file `min(a)=1, max(a)=8, max(b)=12`.

`agg_dyn_two_col` and `agg_dyn_mixed` were not in the reported failure
but shared
the same latent race (differing per-file extremes), so they are fixed
too.
`agg_dyn_nulls` is left untouched — its filter is always `true` and
never races.

The expected plan text is **unchanged**; only the input data and the
misleading
comments are modified. The alternative of forcing a single partition was
rejected: dynamic aggregate filters are only emitted in `Partial+Final`
mode
(`target_partitions >= 2`), so a single partition would emit no filter
at all.

## Are these changes tested?

Yes — the modified `push_down_filter_regression.slt` itself is the test.
It
passes, and because the asserted filter content no longer depends on
partition
scheduling, it is stable across runs (verified by running it repeatedly
locally).

## Are there any user-facing changes?

No. Test-only change.

-//! Command-line inspection for SQL benchmark suites.
-//!
-//! This module backs the `benchmark_runner` binary. The initial command
-//! surface lists discovered SQL benchmark suites from `.suite` files and
-//! prints the top-level help.
-//!
-//! Common invocations:
-//!
-//! ```text
-//! cargo run --bin benchmark_runner -- --help
-//! cargo run --release --bin benchmark_runner -- list
-//! ```
-//!
-//! The public entry point is [`run_cli`]. The submodules are kept private so
-//! the command-line flow remains the single supported API:
-//!
-//! - `cli` builds the clap command tree and parses the selected command.
-//! - `suite` loads `.suite` metadata and discovers benchmark query files.
-//! - `output` formats colored `list` command output.

Subject: [PATCH 128/878] perf(optimizer): EliminateCrossJoin fast-path for
 join-free plans (#22612)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Closes #22583.

## Rationale for this change

`EliminateCrossJoin::rewrite` is called on every plan during logical
optimization. The rule's body only does real work when the root (or its
`Filter` child) is an inner `Join`; in every other case it falls through
to `rewrite_children`, which recurses into the plan, processes
uncorrelated subqueries, and rewrites every direct child via
`map_children` (clone-on-write), then calls `recompute_schema` on the
way back.

This is paid by every query in the logical optimizer pipeline —
including simple point queries with no joins anywhere in the tree.

## Discussion on the issue

@neilconway raised the valid concern that a fast-path scan still does
*some* up-front work in the case where the rewrite does fire, and that
the deeper fix is mutable tree rewrites (avoiding the clone-on-write of
`TreeNode::rewrite` entirely). @alamb agreed and pointed at the in-place
`map_children_mut` / `plan_has_subqueries` infrastructure adriangb
landed in #22298 as the existing precedent.

This PR follows that precedent directly:

- **Same shape as `plan_has_subqueries`** — a read-only `apply` scan,
early-stops on the first matching node, allocates nothing.
- The scan cost on a query that *does* have joins is
O(depth-to-first-join) — typically a handful of nodes, well below the
cost of even one `map_children` clone-on-write the rewrite would
otherwise do.
- For the deeper "in-place mutable rewrite" direction,
`rewrite_children` here recurses via `optimizer.rewrite(input, config)`
per child — a different shape from `map_children_mut`'s `&mut`
traversal. Adapting that is a larger refactor and worth its own
follow-up; this PR doesn't block it.

## What changes are included in this PR?

- New `plan_has_joins(&LogicalPlan) -> bool` helper in
`eliminate_cross_join.rs` — `apply` walk that returns `true` on the
first `LogicalPlan::Join` it sees.
- Fast-path at the top of `EliminateCrossJoin::rewrite`: `if
!plan_has_joins(&plan) { return Ok(Transformed::no(plan)); }`.
Everything else is unchanged.

## Are these changes tested?

Four new unit tests in the existing `mod tests`:

- `plan_has_joins_detects_root_join`
- `plan_has_joins_detects_nested_join` (Join under Filter/Projection)
- `plan_has_joins_returns_false_for_join_free_plan`
- `rewrite_short_circuits_when_plan_has_no_joins` — end-to-end: rule's
`rewrite` returns `Transformed::no` and the plan comes back identical
(schema + display) on join-free input.

The existing 20 `EliminateCrossJoin` tests + the full 708-test
`datafusion-optimizer --lib` suite still pass. `cargo clippy -p
datafusion-optimizer --all-targets -- -D warnings` clean.

## Are there any user-facing changes?

No semantic change. Pure perf optimization, no new config knobs.

## Follow-ups

- A deeper architectural improvement (mutable tree rewrites following
the `map_children_mut` pattern from #22298) is worth considering — see
issue #22583 comments for discussion. Out of scope here.

Subject: [PATCH 129/878] fix: make PushDownLeafProjections work with unnest
 (#22620)

## Which issue does this PR close?

Closes https://github.com/apache/datafusion/issues/22615.

## Rationale for this change

`PushDownLeafProjections` throws an error when it tries to push down an
expression through an `Unnest` node. It also tries to push leaf
projections incorrectly for `Unnest` nodes.

## What changes are included in this PR?

This PR makes PushDownLeafProjections never push down leaf expressions
through Unnest nodes. This avoids the code in `try_push_into_inputs`
from calling:
```
let new_node = node.with_new_exprs(node.expressions(), new_inputs)?;
```
on an Unnest node, which doesn't work.

Changing that line is not enough, as even in that case the code in
`try_push_into_inputs` to decide when to push down a projection is not
valid for Unnest nodes, as explained in
https://github.com/apache/datafusion/issues/22615

In this PR, I only want to make sure that the optimizer works for Unnest
cases, but we could probably do better and allow leaf expressions push
downs when the expression refer to a column that is not being unnested.

## Are these changes tested?

Added unit tests and `.slt` tests for these cases.

## Are there any user-facing changes?

No

Subject: [PATCH 130/878] fix array_repeat scalar path overflows total
 repeated-value count (#22274)

## Which issue does this PR close?

- Closes #22218

## Rationale for this change

The scalar path of array_repeat can overflow while computing the total
number of repeated values. Previously, the implementation used unchecked
accumulation for these totals, which could lead to overflow behavior
that was not explicitly handled. This change makes the capacity and
offset calculations overflow-safe and returns a clear execution error
when the total output size exceeds usize.

## What changes are included in this PR?

- Adds overflow checks for the total repeated value count in the scalar
array_repeat path.
- Adds overflow checks for outer and inner total size calculations in
the list repeat path.
- Preserves the existing behavior where non-positive counts are treated
as zero.
- Adds sqllogictest coverage for the overflow error case.

## Are these changes tested?

- Yes. A new sqllogictest covers the scalar overflow failure case for
array_repeat.
- Existing related tests continue to pass.

## Are there any user-facing changes?

- Yes. For extremely large inputs, array_repeat now returns a clear
execution error instead of relying on implicit overflow behavior.
- Normal inputs are unchanged.

      let total_byte_size = left_stats
          .total_byte_size
          .multiply(&right_stats.total_byte_size)
          .multiply(&Precision::Exact(2));
```

This is wrong (e.g., it multiplies two byte-size values together). The
correct formula is "left-num-rows * right-size-in-bytes + right-num-rows
* left-size-in-bytes", since the left side is repeated once per row on
the right, and vice versa.

## What changes are included in this PR?

* Fix total byte size formula for cross join
* Update expected SLT results

## Are these changes tested?

Yes; covered by existing tests.

## Are there any user-facing changes?

No.

Subject: [PATCH 132/878] fix: Correctly compute nullability in recursive CTE
 schemas (#22552)

## Which issue does this PR close?

- Closes #22034.

## Rationale for this change

Nullability analysis for recursive CTEs had two shortcomings:

1. The output schema of the `RecursiveQuery` was derived solely from the
static (anchor) term. This is incorrect; the recursive term might widen
nullability for some of the output columns.

2. The schema of the CTE work table was derived solely from the static
term. This is only correct for the first iteration of recursive CTE
evaluation; on subsequent iterations, NULLs might have been deposited
into the work table, so the static term's nullability properties may not
hold.

In this PR, we fix the first issue by computing the output schema of the
`RecursiveQuery` by taking the union of the per-column nullability of
the static and recursive terms. The output schema of the
`RecursiveQuery` is stored explicitly, matching the approach taken for
most logical plan nodes.

We fix the second issue by conservatively marking the work table's
columns as nullable. We could compute nullability precisely by
repeatedly doing nullability analysis until we reach fixed point, but
for now we take the simpler and cheaper approach.

## What changes are included in this PR?

* Add explicit schema to `RecursiveQuery`, computed by widening the
per-column nullability of the static and recursive terms
* Conservatively mark CTE worktable columns as nullable
* Recompute `RecursiveQuery` schema as part of proto deserialization,
rather than attempting to serialize it
* Add unit and SLT tests

## Are these changes tested?

Yes; new unit and SLT tests added, existing tests updated.

## Are there any user-facing changes?

Behavioral: nullability analysis for CTEs will be less buggy.

API: `RecursiveQuery` is a `pub struct` that has a new field (`schema`),
and no longer derives `PartialOrd`.

Subject: [PATCH 133/878] Refactor Spark `format_string` integer conversion
 dispatch (#22388)

## Which issue does this PR close?

* Closes #22163

## Rationale for this change

`ConversionSpecifier::format` contained substantial duplication across
integer `ScalarValue` variants for `%d`, `%x`, `%o`, `%s`, and `%c`
handling. Each integer width repeated nearly identical conversion logic,
making the code harder to maintain and increasing the risk of
inconsistent behavior across integer types.

This change consolidates integer formatting behavior into shared
internal helpers while preserving existing Spark-compatible semantics.

## What changes are included in this PR?

* Introduced a local `IntegerValue` enum to normalize signed and
unsigned integer handling while preserving width-specific unsigned bit
behavior for `%x` and `%o`.
* Replaced repeated per-variant integer dispatch branches in
`ConversionSpecifier::format` with a shared `format_integer` helper.
* Added shared helper methods for:

  * decimal formatting
  * unsigned bit formatting
  * `%c` conversion
  * decimal string conversion
* Added small `macro_rules!` helpers to generate `From<T> for
IntegerValue` implementations for signed and unsigned integer families,
reducing repetitive conversion boilerplate while preserving
width-specific unsigned formatting semantics.
* Added `invalid_integer_conversion` helper to centralize integer
conversion error generation.
* Added table-driven regression coverage for integer formatting behavior
across:

  * signed integer widths
  * unsigned integer widths
  * `%d`, `%x`, `%o`, `%s`, and `%c`
  * null handling behavior

## Are these changes tested?

Yes.

Added `test_integer_formatting_across_widths` covering:

* Signed integer formatting across `Int8`, `Int16`, `Int32`, and `Int64`
* Unsigned integer formatting across `UInt8`, `UInt16`, `UInt32`, and
`UInt64`
* `%d`, `%x`, `%o`, `%s`, and `%c` formatting behavior
* Null integer formatting behavior

## Are there any user-facing changes?

No intended user-facing behavior changes. This PR is a structural
refactor intended to preserve existing Spark-compatible integer
formatting semantics.

Subject: [PATCH 134/878] Allow specifying an arrow schema for PartitionedFile
 (#22360)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes https://github.com/apache/datafusion/issues/22200.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

As described in the linked issue, parsing the arrow schema from parquet
metadata can be expensive for point lookups, relative to the rest of the
query execution pipeline. If the user knows the arrow schema of the
file, they should be able to specify it explicitly.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

* Add a `arrow_schema: SchemaRef` field to `PartitionedFile`
* Use the `arrow_schema` field in the parquet opener to bypass schema
inference from the `ARROW:schema` metadata field.

## Are these changes tested?

Added unit tests for both matching and mismatching schemas.

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

There are no breaking changes, the new field is optional and is set to
None by default.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 135/878] Track allocator-level memory vs MemoryPool during
 SLTs to prevent OOMs (#22626)

## Which issue does this PR close?

Closes #22627.

## What & why

A test opts in with `SET datafusion.runtime.memory_limit = 'N'`; the
wrapping `AccountingMemoryPool` then panics the query if real heap
allocations exceed `N * 1.10`. Catches the silent-OOM bug class where
DF's voluntary `MemoryPool` undercounts. Off by default.

## Changes

**Upstream** (`execution/src/memory_pool/`, `runtime_env.rs`)
- New `MemoryPool::try_resize(usize) -> Result<()>`, default
`Err(NotImplemented)`. `GreedyMemoryPool` (now `AtomicUsize` pool_size)
  and `TrackConsumersPool` override.
- `RuntimeEnvBuilder::with_memory_limit` tries `try_resize` before
  wholesale replacement so wrappers survive `SET memory_limit`.

**SLT runner** (`datafusion/sqllogictest/`)
- `AccountingAllocator`: global allocator, per-file account
  (`HashMap<ContextId, AtomicIsize>`). Context-id stamped on workers
  via per-file Tokio runtime + `on_thread_start`.
- `AccountingMemoryPool` wraps DF's pool. `try_resize` retunes the
  account to `N * 1.10`. Renders the operator-set default as `Infinite`
  so un-opted tests' `SHOW ALL` is unchanged.
- One CLI flag, `--default-pool-size-mb` (replaces `--total-memory-mb`
  + `--datafusion-memory-fraction`).
- README + contributor-guide updated.

## Testing

- `memory_pool` and SLT-accounting unit tests pass.
- Full 475-file SLT corpus passes under `--default-pool-size-mb 16384`.

## User-facing

API non-breaking. `--total-memory-mb` and `--datafusion-memory-fraction`
replaced by `--default-pool-size-mb`. End-user query behavior unchanged.

---

```
[aggregate.slt] killed by allocator overdraft:
  account balance = -110983311 bytes, df-pool reserved = 0 MB;
  sql = "SELECT array_agg(c13 ORDER BY c13) FROM ..."
```
`df-pool reserved = 0 MB` next to a deeply-negative balance is the
discrepancy this PR surfaces.

+## Running tests: allocator-level memory accounting
+
+Build with `--features memory-accounting` to install a global allocator
+wrapper that tracks actual bytes allocated per SLT file and reconciles them
+against DataFusion's voluntary `MemoryPool` tracking. The point isn't to
+enforce a process-wide budget — it's to catch DataFusion lying about how
+much memory it's using. If `MemoryPool` reports 1 MB while the allocator
+sees 100 MB go by, _that gap is the bug_.
+
+```shell
+cargo test --features memory-accounting --test sqllogictests -- \
+    --default-pool-size-mb 16384
+```
+
+`--default-pool-size-mb` seeds each per-file SLT context's MemoryPool with
+the given size in MB and arms the bank as a no-op until a test opts in.
+
+**Opting an individual test in.** Add `SET datafusion.runtime.memory_limit = 'N'` at the top of the `.slt`. The wrapping `AccountingMemoryPool` then
+tightens its allocator-level bank to `N * 1.10` (10% headroom). If the test
+allocates more than that — including bytes DataFusion's tracker didn't see
+— the test panics with an `OverdraftPanic` reporting the actual balance at
+panic time. SLTs without a `SET` of `memory_limit` see no change in
+behavior; the bank stays loose and `SHOW ALL` continues to render the limit
+as `unlimited`.
+
+Inside the runner each file gets its own multi-thread Tokio runtime so
+context-ids stamped onto worker threads stay stable for the allocator
+hook, and per-file accounts in the bank are isolated from each other.

+//! Allocator-driven memory accounting with per-context budgets.
+//!
+//! The bank ([`ACCOUNTS`]) holds one [`AtomicIsize`] account per stamped
+//! `CONTEXT_ID`, each tracking its own remaining budget. Allocations debit
+//! the current thread's account, deallocations credit it; below zero is an
+//! overdraft. Threads with `CONTEXT_ID == 0` (main, the outer orchestration
+//! runtime, blocking-pool hosts) are untracked and skip the hot path.
+//!
+//! Per-alloc bookkeeping accumulates in a thread-local `LOCAL_BALANCE`
+//! drift counter; it settles into the account once `|drift|` crosses
+//! [`SETTLE_THRESHOLD`] (64 KB), amortizing the `RwLock` read + atomic
+//! op across thousands of allocations.
+//!
+//! [`account_balance`] reads the current thread's account; it lags reality
+//! by up to one threshold's worth of un-settled drift per thread.
+//!
+//! # Enforcement
+//!
+//! An allocation that drives the bank negative on a stamped thread
+//! (`CONTEXT_ID != 0`) panics with [`OverdraftPanic`] on the polling thread.
+//! Drop-chain credits during unwind never re-panic — `track` only fires on
+//! debits (`delta < 0`). Unstamped threads are silently skipped.
+//!
+//! Compiled in only when the `memory-accounting` feature is on.

+
+For tests that need to verify DataFusion's voluntary memory tracking
+matches actual heap usage, the `sqllogictest` runner ships an optional
+`memory-accounting` feature that installs a global allocator wrapper.
+Adding `SET datafusion.runtime.memory_limit = 'N'` at the top of an
+`.slt` file opts that file into allocator-vs-`MemoryPool` reconciliation
+with 10% headroom — any divergence panics the test with an
+`OverdraftPanic` reporting the actual allocator balance. See
+[the sqllogictest README](https://github.com/apache/datafusion/blob/main/datafusion/sqllogictest/README.md#running-tests-allocator-level-memory-accounting)

Subject: [PATCH 136/878] perf: optimize date subtraction to avoid intermediate
 array allocation (#22591)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

When evaluating `Date32 - Date32` or `Date64 - Date64`, DataFusion needs
to return an Int64 representing the difference in days(after #19563).
The current implementation went through Arrow's sub_wrapping, then
converted to Int64 days. This allocates an unnecessary intermediate
array and bypasses vectorized kernels.

Since Date32/Date64 are just i32/i64 under the hood, we can compute the
day difference directly on the native values.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

- Replace `apply_date_subtraction + duration_to_days` with
`subtract_date_to_days`, which operates directly on primitive values
using `binary()/unary()`
- Add date subtraction benchmarks

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.

Subject: [PATCH 138/878] refactor: Port TryCastExpr proto serialization hooks
 (#22550)

## Which issue does this PR close?

- Closes #22429.

## Rationale for this change

This is part of #22418, which migrates built-in `PhysicalExpr`
implementations away from the central protobuf serialization /
deserialization chains.

`TryCastExpr` can now own its protobuf serialization through
`PhysicalExpr::try_to_proto` and its deserialization through
`TryCastExpr::try_from_proto`, matching the pattern used by previously
migrated physical expressions.

## What changes are included in this PR?

- Adds `PhysicalExpr::try_to_proto` support for `TryCastExpr`.
- Adds `TryCastExpr::try_from_proto`.
- Wires `TryCastExpr` deserialization in `from_proto.rs` through the new
hook.
- Removes the old `TryCastExpr` serialization branch from the central
`to_proto.rs` downcast chain.
- Adds direct proto hook tests for successful encoding / decoding and
invalid protobuf inputs.

## Are these changes tested?

Yes.

I ran:

```bash
cargo fmt --all --check
git diff --check
cargo test -p datafusion-physical-expr --features proto try_cast
cargo test -p datafusion-proto --test proto_integration
cargo clippy -p datafusion-physical-expr --features proto --tests -- -D warnings
cargo clippy -p datafusion-proto --tests -- -D warnings
```

## Are there any user-facing changes?

No. This is an internal protobuf serialization refactor for
`TryCastExpr`; the wire format remains unchanged.

Subject: [PATCH 139/878] fix nth_value window function negates i64::MIN
 (#22304)

## Which issue does this PR close?

- Closes #22222.

## Rationale for this change

`nth_value` could panic at execution time when called with `i64::MIN` as
the `n` argument. The implementation supports negative `n` for reverse
indexing and negated the value internally, but negating `i64::MIN`
overflows. This caused a runtime panic instead of returning a normal
DataFusion error for invalid input.

## What changes are included in this PR?

This PR adds validation for the second argument of `nth_value` so that
`i64::MIN` is rejected before any negation occurs. Instead of panicking
during execution, the function now returns a regular execution error.

This PR also adds regression coverage at two levels:
- a unit test for the `nth_value` window function implementation
- a sqllogictest case covering the SQL query shape that previously
triggered the panic

## Are these changes tested?

Yes.

The change is covered by:
1. a focused unit test in the window function implementation
2. a SQL logic test in `window.slt`

Validated with:
1. `cargo test -p datafusion-functions-window nth_value --lib`
2. `cargo test -p datafusion-sqllogictest --test sqllogictests window`

## Are there any user-facing changes?

Yes. Queries that previously panicked when calling `nth_value(...,
-9223372036854775808)` now return a proper execution error instead.

Subject: [PATCH 140/878] fix: Improve consistency of per-column stats on
 `FilterExec` output (#22718)

## Which issue does this PR close?

- Closes #22716

## Rationale for this change

#21081 capped the NDV at the row count when computing statistics for
several operators. This PR extends that work and ensures that per-column
statistics for filter operators are consistent with the estimated output
row count. In particular:

* Null count is also capped at the row count
* Byte size is scaled down by the estimated selectivity

We also extend the analysis to consider null-rejecting predicates; for
example, the clause `a = 10` as a top-level conjunct implies that the
null-count of the surviving rows is exactly 0.

## What changes are included in this PR?

* Ensure per-column statistics (null count, byte size) are consistent
with filtered row count
* Check for null-rejecting predicates to estimate a more accurate null
count of 0
* Update SLT expected plans
* Add unit tests for new behavior
* Various refactoring and comment improvements

## Are these changes tested?

Yes; new tests added.

## Are there any user-facing changes?

No.

Subject: [PATCH 141/878] fix: Correct computation of selectivity for multi-key
 joins (#22725)

## Which issue does this PR close?

- Closes #22724

## Rationale for this change

`estimate_inner_join_cardinality` sets `join_selectivity` to the
selectivity of the last join key in the list. The intent was almost
surely to instead use the selectivity of the most selective join key
instead.

## What changes are included in this PR?

* Fix formula for multi-key join selectivity estimation
* Improve comment to reference Spark Catalyst behavior more clearly
* Add unit test

## Are these changes tested?

Yes, new test added.

## Are there any user-facing changes?

No.

Subject: [PATCH 142/878] refactor: give parquet CDC options an explicit
 `enabled` flag (#22632)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- None

## Rationale for this change

The CDC options currently work as `use_content_defined_chunking:
Option<CdcOptions>` with a `ConfigField` impl that accepts a bare
`use_content_defined_chunking = true|false` and otherwise enables CDC
implicitly when any sub-field is set. This has a few problems:

- **Naming diverges from parquet-rs.** `WriterProperties` exposes
`content_defined_chunking()` /
`set_content_defined_chunking(Option<CdcOptions>)` with no `use_`
prefix.
- **Implicit / order-dependent on the SQL side.** Format options in
`COPY ... OPTIONS` / `CREATE EXTERNAL TABLE ... OPTIONS` are applied
from a `HashMap` (non-deterministic order). With the old bare-boolean
form, mixing `... = false` with a sub-field, or setting a sub-field
after `= false`, could resolve to enabled or disabled depending on
iteration order.
- **Extra machinery.** Supporting the bare boolean required a
hand-written `impl ConfigField for CdcOptions` + `impl ConfigField for
Option<CdcOptions>` and a `#[expect(clippy::should_implement_trait)]`
workaround, plus a zero-sentinel fallback in the proto mapping.

Since CDC is unreleased, the config/proto surface can still be changed
freely.

## What changes are included in this PR?

- Rename the `ParquetOptions` field `use_content_defined_chunking` ->
`content_defined_chunking` (matches parquet-rs).
- Make `CdcOptions` a plain `config_namespace!` with an explicit
`enabled: bool` field alongside the chunking parameters; the field is a
bare `CdcOptions` (no longer `Option<CdcOptions>`). CDC is on if
`content_defined_chunking.enabled` is true. Setting a parameter no
longer implicitly enables CDC, and the result is independent of key
order.
- Add `CdcOptions::enabled()` / `CdcOptions::disabled()` shorthand
constructors.
- Drop the `ConfigField` impls and the `should_implement_trait`
workaround — all generated by the macro now.
- Add an `enabled` field to the proto `CdcOptions` message so the proto
<-> config mapping is a plain field copy in both directions (removes the
presence-encoding and the zero-sentinel fallback).
- Update unit tests, regenerate config docs + the `information_schema`
snapshot, and add `parquet_cdc_config.slt` documenting the resolution
behavior.

## Are these changes tested?

Yes:
- `datafusion-common` config + writer unit tests (enable toggle,
parameter-does-not-enable, validation, writer round-trip).
- `datafusion-proto-common` proto round-trip tests (enabled / disabled /
negative norm level).
- `datafusion/core` parquet integration tests (data round-trip, page
boundaries).
- sqllogictest: `parquet_cdc.slt` (end-to-end) and a new
`parquet_cdc_config.slt` (config resolution / order independence).

## Are there any user-facing changes?

Yes, but only to the unreleased CDC options:
- Config key `datafusion.execution.parquet.use_content_defined_chunking`
-> `datafusion.execution.parquet.content_defined_chunking.enabled` (plus
`.min_chunk_size` / `.max_chunk_size` / `.norm_level`).
- The bare-boolean form is removed; enable/disable via
`content_defined_chunking.enabled = true|false`.

No released API is affected.

Subject: [PATCH 143/878] sqllogictest: account before alloc to avoid
 panic-after-alloc hazards (#22742)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #.

Follow-up defect fix in the allocator-level accounting framework added
by #22626.

## Rationale for this change

`AccountingAllocator::realloc` (introduced in #22626) called
`inner.realloc` first — which frees the caller's old pointer on success
— then called `track`, which can `panic_any` on overdraft. The unwind
starts with the caller's `Vec` (or similar growing container) still
holding the now-freed old pointer; the next `Drop` produces glibc's
`double free or corruption (out)` and SIGABRT, masking the underlying
untracked-allocation panic the framework was trying to surface.

The same hazard does not apply to `alloc` / `alloc_zeroed` / `dealloc`:
- `alloc` / `alloc_zeroed` — the caller has no preexisting pointer to be
invalidated; panicking after the inner alloc just leaks the new
allocation, which is fine on the kill path.
- `dealloc` — credits the bank, never panics.

Only `realloc` has a live caller-side pointer that gets invalidated by
the inner operation before the panic decision.

## What changes are included in this PR?

Reorder `AccountingAllocator::realloc` to account first, forward to
`inner.realloc` second:

- `track(delta)` first — on overdraft we panic with the caller's pointer
still valid; unwind drops the live container cleanly, no abort.
- If `inner.realloc` returns null after a successful track, refund the
delta so the bank stays consistent with what actually got allocated.

## Are these changes tested?

Manually verified using a `GroupedHashAggregateStream` + `List<Utf8>`
group-key reproducer (routes through `GroupValuesRows::intern` →
`RowConverter::append` → `Vec::resize` → `__rust_realloc`, which is one
of the untracked-allocation sites this framework is meant to catch):

- before: exit 101, `double free or corruption (out)`, signal 6 SIGABRT
- after: exit 1, clean `allocator overdraft: account balance at panic =
-1.7 MB` at the same `RowConverter::append` stack frame

A regression test for "panic from inside `realloc` does not double-free"
would require constructing the precise realloc-mid-grow scenario plus a
`catch_unwind` harness; deferred as follow-up.

## Are there any user-facing changes?

No. Confined to `sqllogictest`'s `memory-accounting` feature, which is
internal CI tooling.

<h1>CodeQL Action Changelog</h1>
<p>See the <a

page</a> for the relevant changes to the CodeQL CLI and language
packs.</p>
<h2>[UNRELEASED]</h2>

<h2>4.36.1 - 02 Jun 2026</h2>
<p>No user facing changes.</p>
<h2>4.36.0 - 22 May 2026</h2>
<ul>
<li><em>Breaking change</em>: Bump the minimum required CodeQL bundle
version to 2.19.4. <a
href="https://redirect.github.com/github/codeql-action/pull/3894">#3894</a></li>
<li>Add support for SHA-256 Git object IDs. <a
href="https://redirect.github.com/github/codeql-action/pull/3893">#3893</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.5">2.25.5</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3926">#3926</a></li>
</ul>
<h2>4.35.5 - 15 May 2026</h2>
<ul>
<li>We have improved how the JavaScript bundles for the CodeQL Action
are generated to avoid duplication across bundles and reduce the size of
the repository by around 70%. This should have no effect on the runtime
behaviour of the CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3899">#3899</a></li>
<li>For performance and accuracy reasons, <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> will now only be enabled on a pull request when
diff-informed analysis is also enabled for that run. If diff-informed
analysis is unavailable (for example, because the PR diff ranges could
not be computed), the action will fall back to a full analysis. <a
href="https://redirect.github.com/github/codeql-action/pull/3791">#3791</a></li>
<li>If multiple inputs are provided for the GitHub-internal
<code>analysis-kinds</code> input, only <code>code-scanning</code> will
be enabled. The <code>analysis-kinds</code> input is experimental, for
GitHub-internal use only, and may change without notice at any time. <a
href="https://redirect.github.com/github/codeql-action/pull/3892">#3892</a></li>
<li>Added an experimental change which, when running a Code Scanning
analysis for a PR with <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> enabled, prefers CodeQL CLI versions that have
a cached overlay-base database for the configured languages. This speeds
up analysis for a repository when there is not yet a cached overlay-base
database for the latest CLI version. We expect to roll this change out
to everyone in May. <a
href="https://redirect.github.com/github/codeql-action/pull/3880">#3880</a></li>
</ul>
<h2>4.35.4 - 07 May 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.4">2.25.4</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3881">#3881</a></li>
</ul>
<h2>4.35.3 - 01 May 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.19.3 and earlier. These versions of
CodeQL were discontinued on 9 April 2026 alongside GitHub Enterprise
Server 3.15, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3837">#3837</a></li>
<li>Configurations for private registries that use Cloudsmith or GCP
OIDC are now accepted. <a
href="https://redirect.github.com/github/codeql-action/pull/3850">#3850</a></li>
<li>Best-effort connection tests for private registries now use
<code>GET</code> requests instead of <code>HEAD</code> for better
compatibility with various registry implementations. For NuGet feeds,
the test is now always performed against the service index. <a
href="https://redirect.github.com/github/codeql-action/pull/3853">#3853</a></li>
<li>Fixed a bug where two diagnostics produced within the same
millisecond could overwrite each other on disk, causing one of them to
be lost. <a
href="https://redirect.github.com/github/codeql-action/pull/3852">#3852</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.3">2.25.3</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3865">#3865</a></li>
</ul>
<h2>4.35.2 - 15 Apr 2026</h2>
<ul>
<li>The undocumented TRAP cache cleanup feature that could be enabled
using the <code>CODEQL_ACTION_CLEANUP_TRAP_CACHES</code> environment
variable is deprecated and will be removed in May 2026. If you are
affected by this, we recommend disabling TRAP caching by passing the
<code>trap-caching: false</code> input to the <code>init</code> Action.
<a
href="https://redirect.github.com/github/codeql-action/pull/3795">#3795</a></li>
<li>The Git version 2.36.0 requirement for improved incremental analysis
now only applies to repositories that contain submodules. <a
href="https://redirect.github.com/github/codeql-action/pull/3789">#3789</a></li>
<li>Python analysis on GHES no longer extracts the standard library,
relying instead on models of the standard library. This should result in
significantly faster extraction and analysis times, while the effect on
alerts should be minimal. <a
href="https://redirect.github.com/github/codeql-action/pull/3794">#3794</a></li>
<li>Fixed a bug in the validation of OIDC configurations for private
registries that was added in CodeQL Action 4.33.0 / 3.33.0. <a
href="https://redirect.github.com/github/codeql-action/pull/3807">#3807</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.2">2.25.2</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3823">#3823</a></li>
</ul>
<h2>4.35.1 - 27 Mar 2026</h2>
<ul>
<li>Fix incorrect minimum required Git version for <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a>: it should have been 2.36.0, not 2.11.0. <a
href="https://redirect.github.com/github/codeql-action/pull/3781">#3781</a></li>

<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/astral-sh/setup-uv/releases">astral-sh/setup-uv's
releases</a>.</em></p>
<blockquote>
<h2>v8.2.0 🌈 New inputs <code>quiet</code> and
<code>download-from-astral-mirror</code></h2>
<h2>Changes</h2>
<p>This release brings two new inputs and a few bug fixes.</p>
<h3>New inputs</h3>
<p>Lets talk about the new inputs first.</p>
<h4>quiet</h4>
<p>Pretty simple. It turns of all <code>info</code> loggings. Useful if
you use this in a composite action and are not interested in all the
details.
In the upcoming releases we will add log groups to fully implement
support for &quot;less noise&quot;</p>
<blockquote>
<p>[!NOTE]<br />
Warnings and errors are always logged.</p>
</blockquote>
<h4>download-from-astral-mirror</h4>
<p>In some cases you may want to directly use the fallback of checking
for available versions and downloading releases from GitHub instead of
using the astral.sh mirror. Setting <code>download-from-astral-mirror:
false</code> allows you to do that.</p>
<h3>Bugfixes</h3>
<p>When using the astral.sh mirror to query available versions and
download releases (done by default) we now stop sending the GitHub token
in the header. The mirror never looked at it but we shouldn't be handing
out that data even if it is just a short lived token.
All other bugfixes try to limit the impact of failed GitHub queries due
to retries and other faults.</p>
<p>We couldn't pinpoint all rootcauses yet but added more logging for
error cases to track them down.</p>

Subject: [PATCH 148/878] fix: replace with empty search string should be a
 no-op (#22497)

## Which issue does this PR close?

- Closes #22253
- Closes #22357

## Rationale for this change

PostgreSQL returns the input unchanged when `replace` is called with an
empty `from`. DataFusion was instead inserting `to` before every
character and at both ends, so `replace('abc', '', 'x')` returned
`xaxbxcx`. This PR brings the behaviour in line with PostgreSQL. Part of
the PG-compatibility cleanup tracked in #22247.

## What changes are included in this PR?

- `datafusion/functions/src/string/replace.rs`: the empty-`from` branch
in `apply_replace` now writes the input verbatim instead of inserting
`to`. Added a `LargeUtf8` unit test for the new behaviour.
- `datafusion/sqllogictest/test_files/string/string_literal.slt`: four
new SLT asserts covering the `Utf8`, `Dictionary`, `Utf8View`, and
`LargeUtf8` paths.
- `datafusion/sqllogictest/test_files/string/string_query.slt.part`:
updated four expected rows that were asserting the old buggy output.

## Are these changes tested?

Yes. The unit test in `replace.rs` covers the `LargeUtf8` path, and the
four new SLT asserts in `string_literal.slt` cover the remaining Arrow
string encodings end-to-end. The full SLT suite passes locally.

## Are there any user-facing changes?

Yes. `replace(str, '', x)` now returns `str` unchanged instead of
inserting `x` between every character. This matches PostgreSQL.

Subject: [PATCH 149/878] perf: optimize arrays_zip perfect list zips (#22285)

## Which issue does this PR close?

- Closes #22225.

## Rationale for this change

`arrays_zip` currently uses the general `MutableArrayData` path even
when all regular `ListArray` inputs are already perfectly aligned. In
that case, the output list offsets match the inputs and each struct
child column can reuse the corresponding input values array instead of
copying one row at a time.

## What changes are included in this PR?

- Add a fast path for perfect regular `ListArray` zips that reuses the
first input's offsets and clones the input values arrays into the output
struct children.
- Keep the existing general path for ragged inputs, `LargeList`,
`FixedSizeList`, `Null` inputs, and null rows that would require
padding.
- Add unit coverage for offset/value reuse, zero-length null rows, and
null rows with hidden values falling back to the general path.
- Rename the no-null benchmark case to `arrays_zip_perfect_zip_8192`.

## Are these changes tested?

Yes. Local checks run:

- `cargo fmt --all`
- `cargo test -p datafusion-functions-nested`
- `cargo clippy -p datafusion-functions-nested --all-targets
--all-features -- -D warnings`
- `CARGO_TARGET_DIR=C:\df-target cargo clippy --all-targets
--all-features -- -D warnings`
- `CARGO_TARGET_DIR=C:\df-target cargo bench -p
datafusion-functions-nested --bench arrays_zip -- --warm-up-time 1
--measurement-time 2 --sample-size 10`

Latest local benchmark sample:

- `arrays_zip_perfect_zip_8192`: `11.234 ?s 11.600 ?s 12.045 ?s`
- `arrays_zip_10pct_nulls_8192`: `4.3463 ms 4.5531 ms 4.7898 ms`

## Are there any user-facing changes?

No. This is an internal performance optimization with the same
`arrays_zip` output semantics.

## Review follow-up validation

2026-05-21:

- `cargo fmt --all --check` passed after formatting.
- `cargo test -p datafusion-functions-nested
perfect_zip_uses_supplied_field_names --lib` could not compile locally
because this Windows GNU toolchain is missing `dlltool.exe`.
- `cargo clippy -p datafusion-functions-nested --all-targets -- -D
warnings` hit the same local `dlltool.exe` toolchain blocker before
checking the crate.

Subject: [PATCH 150/878] fix: Remove `power(decimal, int)` code path (#22651)

## Which issue does this PR close?

- Closes #22480
- Closes #22510

## Rationale for this change

`power(decimal, int)` attempted to compute `power` without loss of
precision. For negative exponents, the code did the computation in
`Float64` and then cast the result back to `decimal`. Unfortunately, the
previous implementation got this wrong, because `decimal` might not have
enough precision to accurately represent the result. It seems simpler to
return `Float64` for the negative exponent case.

We could potentially try to return `decimal` only for non-negative
exponents and `Float64` for negative exponents, but that is complicated,
and also means that the code would produce different results for literal
arguments vs. columnar arguments, which I think should be avoided.

On reflection, it seems simplest to just remove the `power(decimal,
int)` code path entirely, and have `power` always return `Float64`. This
also fixes another issue in the decimal code path (#22480)

## What changes are included in this PR?

* Remove `power(decimal, ...)` support; both args will be coerced to
Float64 if necessary, and the function will always return Float64
* Update SLT
* Add new test cases for #22480 and #22510

## Are these changes tested?

Yes.

## Are there any user-facing changes?

Yes, `power(decimal, ...)` will now return `Float64`.

-/// Binary function to calculate a math power to integer exponent

-///
-/// Formula
-/// The power for a scaled integer `b` is
-///
-/// ```text
-/// (b * 10^(-s)) ^ e
-/// ```
-/// However, the result should be scaled back from scale 0 to scale `s`,
-/// which is done by multiplying by `10^s`.
-/// At the end, the formula is:
-///
-/// ```text
-///   b^e * 10^(-s * e) * 10^s = b^e / 10^(s * (e-1))
-/// ```
-/// Example of 2.5 ^ 4 = 39:
-///   2.5 is represented as 25 with scale 1
-///   The unscaled result is 25^4 = 390625
-///   Scale it back to 1: 390625 / 10^4 = 39

Subject: [PATCH 151/878] feat: support Boolean in approx_distinct (#22707)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Which issue does this PR close?**

No issue is open for Boolean specifically. Related: #1109 (closed by
#21453) introduced the bitmap pattern this PR extends. The pre-#21453
code carried a `// TODO support for boolean (trivial case)` comment that
was silently
[dropped](https://github.com/apache/datafusion/pull/21453/changes#diff-1b528be54cb05b65e70e59af3016c21deb39cdeedfe5bfd554cdc3e47694f81eL345)
without implementation.

**Rationale for this change**

Today `approx_distinct(bool_col)` errors with *"Support for
'approx_distinct' for data type Boolean is not implemented"*. Boolean
has at most **2** distinct non-null values, so HLL is overkill — a tiny
pair of flags gives an **exact** answer at a fraction of the memory
cost, matching the small-int bitmap strategy already in the codebase.

**What changes are included in this PR?**

Adds `BooleanDistinctCountAccumulator` (two named flags:
`has_seen_false` / `has_seen_true`) in `functions-aggregate-common` and
wires `DataType::Boolean` through the existing
`ApproxDistinctBitmapWrapper` in `approx_distinct.rs` alongside the
small-int arms. State serializes as `List<Boolean>`.

**Are these changes tested?**

Yes — SLT regression coverage in `aggregate.slt` for all-true,
all-false, mixed, all-null, and `GROUP BY` cases.

**Are there any user-facing changes?**

Yes — `approx_distinct(<boolean>)` now works instead of erroring. No API
or behavioral changes for existing types.

Subject: [PATCH 152/878] fix: avoid extraneous casts for equivalent nested
 types (#20945)

## Summary

This PR avoids inserting extraneous casts during function argument
coercion when two nested types are structurally equivalent but differ
only in nested field names or metadata.

Specifically, it:
- treats equivalent nested `DataType`s as matching during UDF argument
coercion
- avoids rewriting such arguments with unnecessary `CAST`s
- adds regression coverage in both `datafusion-expr` and
`datafusion-optimizer`

Closes #19943.

## Tests

- `cargo test -p datafusion-optimizer`
- `./dev/rust_lint.sh`
- `cargo test -p datafusion-expr` currently fails on an existing
snapshot mismatch in `logical_plan::plan::tests::test_display_pg_json`
on the current `main` baseline, unrelated to this change

Subject: [PATCH 153/878] fix date_bin overflows scaling extreme
 Timestamp(Second) source (#22315)

## Which issue does this PR close?

- Closes #22211.

## Rationale for this change

`date_bin` could panic during planning or constant evaluation when
scaling a non-nanosecond source timestamp to nanoseconds overflowed.
This change makes that path return a regular error instead of panicking.

## What changes are included in this PR?

- Added checked overflow handling for source timestamp scaling in
`date_bin`.
- Return an error for out-of-range source timestamp conversion instead
of panicking.
- Preserved existing `NULL` behavior for unrelated out-of-range
`date_bin` cases.
- Added Rust unit test and sqllogictest coverage for the overflow case.

## Are these changes tested?

Yes.

Verified with:

- `cargo test -p datafusion-functions test_date_bin --lib`
- `cargo test -p datafusion-sqllogictest --test sqllogictests
date_bin_errors`

## Are there any user-facing changes?

Yes. Queries that previously could panic now return a normal error:

`Execution error: DATE_BIN source timestamp ... cannot be represented in
nanoseconds`

Subject: [PATCH 154/878] Add `array_product` UDF (#22703)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

 - Part of #21536 (vector math + array aggregate functions family).

## Rationale for this change

## What changes are included in this PR?

- datafusion/functions-nested/src/array_product.rs — new ArrayProduct
UDF and kernel.
- datafusion/functions-nested/src/lib.rs — three registration sites
(module, expr_fn, all_default_nested_functions).
  - datafusion/sqllogictest/test_files/array_product.slt — SLT coverage.

## Are these changes tested?

yes using UT

## Are there any user-facing changes?
Yes — adds two new SQL scalar functions, array_product and its alias
list_product. No API breakage.

 - `name` - returns the name of the rule

Subject: [PATCH 156/878] perf: Reorder predicates in conjuncts via simple
 heuristic (#22343)

## Which issue does this PR close?

- Closes #11262.

## Rationale for this change

If a filter consists of a mix of cheap and expensive predicates,
evaluating the cheap predicates first can improve performance, because
it reduces the number of rows that the expensive predicate must be
evaluated on. This PR implements this idea, by reordering predicates in
a conjunction to place "cheap" predicates first.

Predicates are assessed as "cheap" or "expensive" using an intentionally
simple heuristic: "cheap" predicates are expressions that consist of
only cheap operations like binary comparisons, negations, and casts, and
"expensive" predicates are everything else (e.g., `LIKE`, regexp
matching, subqueries, and function calls). Composite expressions like
`CASE` are considered cheap only if all of the expressions they contain
are cheap. We use a stable sort when reordering predicates, which means
that the input order of operations is preserved within these two
classes.

Arbitrarily more sophisticated schemes for predicting predicate
evaluation cost (and selectivity) are possible, but a simple approach
seems like a good place to start.

We avoid reordering predicates if the filter contains a volatile
expression.

We don't reorder operands to `OR`: I believe this would be worth doing
if #22342 is implemented.

On ClickBench, this improves performance by ~10-13% on Q21 and ~5% on
Q22, in both cases by reordering simple comparisons to run before `LIKE`
predicates.

## What changes are included in this PR?

* Add a new `reorder_predicates` helper
* Invoke `reorder_predicates` as part of the `PushDownFilter` rewrite
pass
* Add unit tests for `reorder_predicates`
* Update expected query plans in SLT
* Add migration guide note for change to predicate evaluation order

## Are these changes tested?

Yes. Added new unit tests for predicate reordering behavior, updated
some expected `EXPLAIN` output.

## Are there any user-facing changes?

Yes. Users that expect their predicates to be evaluated in a strictly
left-to-right manner might see changes in performance and/or behavior.
Performance changes could be improvements or regressions. Behavioral
changes are possible if the query includes fallible operations like
certain casts or division by zero. Note that the SQL standard is clear
that implementations are allowed to evaluate predicates in any order, so
user queries that depend on an evaluation order are fundamentally
fragile.

   `ScalarSubqueryExpr` expression. Code that walks or transforms `LogicalPlan` /
   `ExecutionPlan` trees, as well as `EXPLAIN` output, may need updating.
 
+### Filter predicate evaluation order may differ from query text
+
+The logical optimizer now reorders filters so that cheap predicates (most binary
+comparisons, `IS NULL`, `Between`, `InList`, etc.) evaluate before expensive
+ones (`LIKE`, regex, scalar function calls, subqueries). For example,
+`WHERE col LIKE '%foo%' AND col2 = 5` may evaluate `col2 = 5` before
+`col LIKE '%foo%'`.
+
+**Evaluation order has never been guaranteed to match the order written in the
+query.** The SQL standard explicitly allows implementations to evaluate operands
+in any order; major engines (PostgreSQL, SQL Server, Oracle, MySQL) document the
+same. Queries should not rely on left-to-right evaluation or short-circuit
+semantics for `AND` or `OR`. Previous versions of DataFusion already reordered
+predicates (e.g., as part of expression simplification or predicate pushdown);
+the new reordering pass just increases the scenarios where the optimizer will
+change predicate evaluation order.
+
+**Fallible-predicate patterns are particularly affected.** For example:
+
+```sql
+WHERE s ~ '^[0-9]+$' AND CAST(s AS INT) > 0
+```
+
+The intent is likely to filter non-numeric strings before the `CAST` runs,
+but this depends on evaluation-order behavior the SQL standard does not
+guaranteed. The new reorder makes this kind of pattern more likely to fail
+at runtime if the optimizer moves the `CAST` ahead of the regex. To force
+conditional evaluation, rewrite using `CASE`, which has standardized
+short-circuit semantics:
+
+```sql
+WHERE CASE WHEN s ~ '^[0-9]+$' THEN CAST(s AS INT) > 0 ELSE false END
+```
+
+Volatile expressions (`random()`, `now()`, etc.) are exempt — their position
+in the conjunct list is preserved so the number of times they evaluate per
+query does not change.

Subject: [PATCH 157/878] test: benchmarks and SLT tests for push-down TopK
 through join (#22760)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Relates to https://github.com/apache/datafusion/issues/11900

## Rationale for this change

This splits the test and benchmark scaffolding out of #21621 so the
`PushDownTopKThroughJoin` optimizer rule itself can be reviewed in
isolation, with a small, focused diff.

The benchmark and SLT files here do not depend on the rule. They are
committed first so that:

1. The benchmark can measure the rule's effect against a baseline that
   does not register it.
2. The follow-up rule PR's diff shows exactly which plans change, since
   the EXPLAIN plans here capture the current (pre-rule) behavior.

## What changes are included in this PR?

- A `push_down_topk` benchmark (`dfbench push-down-topk`) that runs
  `ORDER BY <cols> LIMIT N` queries over outer joins against TPC-H
  `customer`/`orders`/`nation`, plus its query files under
  `benchmarks/queries/push_down_topk/`.
- `push_down_topk_through_join.slt` covering the scenarios the rule
  handles: preserved-side sort keys, ineligible join types
  (inner/full/semi/anti), `ON`-clause filters, projection and
  `SubqueryAlias` resolution, existing child sorts, ties, multi-level
  joins, `OFFSET`, and volatile expressions.

The EXPLAIN plans assert current behavior (TopK not yet pushed through
the join). The follow-up PR that adds the rule updates those plans in
place; the query-result checks hold regardless of whether the rule is
enabled.

The new optimizer rule, the `push_down_limit.rs` changes, and the
`optimizer_rule_reference.md` update from #21621 are intentionally left
for the follow-up PR.

## Are these changes tested?

Yes — this PR is the tests. `push_down_topk_through_join.slt` passes
against `main`, and the benchmark binary compiles and runs.

## Are there any user-facing changes?

No. No API changes; only new benchmark and test files plus benchmark CLI
wiring.

Subject: [PATCH 158/878] Refactor hash join build-report lifecycle into
 `BuildReportHandle` (#22623)

## Which issue does this PR close?

* Closes #22622.

## Rationale for this change

The build-report lifecycle for hash-join partitions was previously
spread across `HashJoinStream`, `OnceFut` polling, and drop-time
cancellation logic. Although correctness around scheduled versus
delivered reports had already been addressed, the lifecycle ownership
remained fragmented and difficult to reason about.

This change centralizes lifecycle management into a dedicated
abstraction, making state transitions explicit and ensuring drop-time
behavior is self-contained and easier to maintain.

## What changes are included in this PR?

* Introduce a new `BuildReportHandle` type that owns the lifecycle of a
partition's build-data report.
* Consolidate report lifecycle state management into explicit states:

  * `NotReported`
  * `Scheduled`
  * `Delivered`
  * `Canceled`
  * `Finalized`
* Move report scheduling, delivery tracking, cancellation, and
finalization logic out of `HashJoinStream` and into `BuildReportHandle`.
* Implement drop-safe behavior in `BuildReportHandle` so pending
scheduled reports are canceled when dropped before delivery.
* Replace the stream's separate accumulator, waiter, and lifecycle state
fields with a single `build_report` handle.
* Add test-only helpers in `shared_bounds.rs` to construct partitioned
accumulators and inspect completed partition counts.
* Update lifecycle documentation to reflect the new centralized
ownership model and state transitions.

## Are these changes tested?

Yes.

New tests were added covering lifecycle behavior and invariants:

* `report_canceled_partition_is_noop_after_report`
* `report_canceled_partition_marks_pending_partition_canceled`
* `build_report_handle_cancels_scheduled_partition_on_drop`
* `build_report_handle_does_not_cancel_delivered_partition_on_drop`
* `build_report_handle_cancel_pending_is_idempotent`
* `build_report_handle_no_accumulator_finalizes`

These tests verify correct cancellation behavior, delivery tracking,
terminal-state handling, and idempotency.

## Are there any user-facing changes?

No. This is an internal refactoring of hash-join build-report lifecycle
management and does not change user-facing behavior.

Subject: [PATCH 159/878] Mark BufferExec and AnalyzeExec as eager (#22711)

## Which issue does this PR close?

- Closes #22708.

## Rationale for this change

`BufferExec` and `AnalyzeExec` both have eager evaluation behavior: they
can drive child streams in spawned tasks instead of performing exactly
one downstream poll worth of work at a time. Their `PlanProperties`
currently report `EvaluationType::Lazy`, so physical-plan metadata does
not describe how these operators execute.

While making that metadata accurate, this PR also keeps
`need_data_exchange(...)` scoped to its original purpose. #4585
introduced that helper as a way to identify physical operators that
require exchange-style handling because they redistribute partitions or
gather multiple input partitions into one output partition. #4586
implemented it for the native exchange/gather operators called out
there: non-round-robin `RepartitionExec`, `CoalescePartitionsExec`, and
`SortPreservingMergeExec`.

The later cooperative-scheduling work in #16398 introduced
`EvaluationType` and made `need_data_exchange(...)` use `evaluation_type
== EvaluationType::Eager`. That shortcut worked when the eager operators
and exchange/gather operators were the same set. With `BufferExec` and
`AnalyzeExec` correctly classified as eager, the shortcut would make
`need_data_exchange(...)` report operators that do eager child polling
but do not perform a data exchange.

So the intended split in this PR is:

- `EvaluationType` describes execution behavior.
- `need_data_exchange(...)` identifies partition redistribution or
partition gathering.

## What changes are included in this PR?

- Mark `BufferExec` as `EvaluationType::Eager` while keeping its
existing cooperative scheduling metadata.
- Mark `AnalyzeExec` as `EvaluationType::Eager` in its computed plan
properties.
- Clarify the `EvaluationType` docs so eager evaluation is not defined
by whether work starts in `execute` or on the first stream poll.
- Restore `need_data_exchange(...)` as an exchange/gather predicate for
the native exchange operators instead of deriving it from all eager
operators.

## Are these changes tested?

Targeted tests pass:

```bash
cargo test -p datafusion-physical-plan --lib buffer::tests
cargo test -p datafusion-physical-plan --lib analyze::tests
cargo test -p datafusion-physical-plan --doc execution_plan
cargo test -p datafusion-physical-plan --lib execution_plan::tests::buffer_exec_does_not_need_data_exchange
RUSTDOCFLAGS="-D warnings" cargo doc -p datafusion-physical-plan --no-deps
```

I also added a focused regression test that `BufferExec` does not
require data exchange. I did not add tests that merely assert the
assigned `EvaluationType`, as those would duplicate the implementation
rather than cover behavior.

## Are there any user-facing changes?

No query-result changes are expected. This updates physical-plan
metadata and keeps `need_data_exchange(...)` scoped to operators that
move data between partitions or gather partitions together.

Subject: [PATCH 160/878] perf: avoid unnecessary large allocations (#22558)

## Which issue does this PR close?
Related a bit to https://github.com/apache/datafusion/issues/22526

~Needs rebasing once https://github.com/apache/datafusion/pull/22416 is
merged~

## Rationale for this change
split_off does this:
> Returns a newly allocated vector containing the elements in the range
[at, len). After the call, the original vector will be left containing
the elements [0, at) with its previous capacity unchanged.

which is bad when taking a small slice from a large Vec, for two
reasons:
* it will allocate memory for the remaining elements, which are a lot
more than n
* it will return a Vec with a very large capacity compared to its length

split_vec_min_alloc still has some issues:
https://github.com/apache/datafusion/issues/22548 but it uses drain +
collect when n is small, which is better because it only allocates for
the initial n elements and doesn't inflate the capacity

## Are these changes tested?
Yes

Subject: [PATCH 161/878] feat(physical-expr): port Literal to try_to_proto /
 try_from_proto hooks (#22636)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Closes #22427

## Rationale for this change

`Literal` serialization/deserialization lived in the central downcast
chains in `to_proto.rs` and `from_proto.rs`. This PR moves it into
self-contained `try_to_proto` / `try_from_proto` hooks on `Literal`
itself, following the pattern established for `NotExpr`, `NegativeExpr`,
`IsNullExpr`, and `IsNotNullExpr`.

## What changes are included in this PR?

- `datafusion/physical-expr/src/expressions/literal.rs`
- Added `#[cfg(feature = "proto")] fn try_to_proto(...)` inside `impl
PhysicalExpr for Literal`
- Added `#[cfg(feature = "proto")] impl Literal { pub fn
try_from_proto(...) }`
- Added `proto_tests` module with encode, null-literal, roundtrip, and
reject-wrong-variant tests
- `datafusion/proto/src/physical_plan/to_proto.rs`
- Removed the `Literal` downcast arm; removed `Literal` from import list
- `datafusion/proto/src/physical_plan/from_proto.rs`
- Replaced the inline `ExprType::Literal` arm with
`Literal::try_from_proto(proto, &decode_ctx)?`

## Are there any user-facing changes?

No. Serialization behaviour is identical; only the code location
changed.

Subject: [PATCH 162/878] Add optimize_with_context to
 FFI_PhysicalOptimizerRule (#22584)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Closes #22334

## Rationale for this change

`FFI_PhysicalOptimizerRule` only plumbed `optimize`, `name`, and
`schema_check` — not `optimize_with_context`. Foreign rules that
override the context-aware variant had their override silently
discarded.

## What changes are included in this PR?

- Added `FFI_PhysicalOptimizerContext` struct to pass optimizer context
(config + statistics registry) across FFI
- Added `optimize_with_context` function pointer to
`FFI_PhysicalOptimizerRule`
- `ForeignPhysicalOptimizerRule` now overrides `optimize_with_context`
to route through FFI
- Unit tests for context-aware round-trip (with and without statistics
registry)

## Are these changes tested?

Yes — two new tests (`test_optimize_with_context_round_trip`,
`test_optimize_with_context_with_registry`) plus all existing tests
continue to pass.

## Are there any user-facing changes?

API change: `FFI_PhysicalOptimizerRule` gains a new field
(`optimize_with_context`). This is a layout change for any external
consumer of this struct.

Subject: [PATCH 163/878] perf(logical-plan): box CreateExternalTable /
 CreateFunction in DdlStatement (-45% LogicalPlan size) (#22733)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Closes #22732.

## Rationale for this change

`LogicalPlan` is 320 bytes today, sized by the `Ddl(DdlStatement)`
variant — which is itself 320 bytes because it carries
`CreateExternalTable` (312 bytes) and `CreateFunction` (288 bytes).
Every non-DDL variant is at most 176 bytes (`Join`). Every SELECT query
pays the full 320-byte payload on every `mem::take` / `mem::swap` /
`Arc<LogicalPlan>` write during planning, even though it never
instantiates a DDL node.

Profiling `sql_planner` (samply, macOS aarch64) showed ~13% of CPU in
`libsystem_platform.dylib` (memcpy / memmove). Shrinking the most
frequently-moved type directly attacks that pool.

## What changes are included in this PR?

Box the two oversized DDL variants:

```rust
pub enum DdlStatement {
    CreateExternalTable(Box<CreateExternalTable>),
    // …
    CreateFunction(Box<CreateFunction>),
    // …
}
```

After this change:

- `DdlStatement` drops from **320 → ~152 bytes** (max variant is now
`CreateIndex` at 144).
- `LogicalPlan` drops from **320 → 176 bytes (–45%)** — the enum
discriminant fits inside `Join`'s alignment padding, so the enum is
exactly the same width as `Join`.

DDL plan construction takes one extra `Box::new(...)` allocation per DDL
statement — negligible because DDL plans are one-shot and not on the
per-query hot path.

The diff is mechanical: construction sites add `Box::new(...)`, the few
field-destructuring patterns are converted to a `let CreateExternalTable
{ … } = ce.as_ref();` shape, and the FFI/proto crates need one `*cmd` /
`Box::new(cmd)` adjustment at the type boundaries.

A new `test_size_of_logical_plan` unit test pins
`size_of::<LogicalPlan>() == 176` and asserts `DdlStatement` stays
smaller than `Join`, so future variant growth that would re-balloon the
enum trips the test rather than silently regressing the planning hot
path. (Same shape as the existing `test_size_of_expr` in `expr.rs`.)

## Are these changes tested?

- 711 optimizer + 217 expr + 86 sql + 7 proto unit tests pass.
- SLT `create_external_table` / `create_function` / `ddl` pass.
- `cargo clippy --workspace --all-targets -- -D warnings` clean.


## Are there any user-facing changes?

Yes (semantic API only). Code that pattern-matches
`DdlStatement::CreateExternalTable(CreateExternalTable { … })` must
change to bind the box and deref. Code that constructs these variants
must wrap with `Box::new(...)`. No behavioral change.

 ```
 
+### `DdlStatement::CreateExternalTable` and `CreateFunction` are now boxed
+
+The two largest variants of `datafusion_expr::DdlStatement` are now
+`Box`ed:
+
+```rust,ignore
+// Before
+pub enum DdlStatement {
+    CreateExternalTable(CreateExternalTable),
+    // ...
+    CreateFunction(CreateFunction),
+    // ...
+}
+
+// After
+pub enum DdlStatement {
+    CreateExternalTable(Box<CreateExternalTable>),
+    // ...
+    CreateFunction(Box<CreateFunction>),
+    // ...
+}
+```
+
+`CreateExternalTable` is 312 bytes and `CreateFunction` is 288 bytes, so
+without boxing they forced the entire `LogicalPlan` enum to 320 bytes
+even on SELECT-only query paths that never instantiate them. Boxing
+shrinks `LogicalPlan` from 320 → 176 bytes (−45%), making every
+`mem::take` / `mem::swap` / `Arc<LogicalPlan>` store on the planning
+hot path move a smaller payload.
+
+**Who is affected:**
+
+- Users who construct `DdlStatement::CreateExternalTable(...)` or
+  `DdlStatement::CreateFunction(...)` from an owned struct.
+- Users who pattern-match these variants and destructure the inner
+  struct in the same pattern (e.g.
+  `DdlStatement::CreateExternalTable(CreateExternalTable { name, .. })`).
+- Code that consumes the inner struct out of these variants (e.g. to
+  pass `CreateExternalTable` by value to another function).
+
+**Migration guide:**
+
+When constructing the variants, wrap the inner struct in `Box::new`:
+
+```rust,ignore
+// Before
+let stmt = DdlStatement::CreateFunction(CreateFunction { name, args, .. });
+
+// After
+let stmt = DdlStatement::CreateFunction(Box::new(CreateFunction {
+    name,
+    args,
+    ..
+}));
+```
+
+When pattern-matching, bind the boxed value and either access fields
+through it (Rust auto-derefs the `Box`) or destructure via `.as_ref()`:
+
+```rust,ignore
+// Before
+match ddl {
+    DdlStatement::CreateExternalTable(CreateExternalTable {
+        name, location, ..
+    }) => { /* use name, location */ }
+}
+
+// After — access fields through the box
+match ddl {
+    DdlStatement::CreateExternalTable(ce) => {
+        let name = &ce.name;
+        let location = &ce.location;
+        /* ... */
+    }
+}
+
+// After — destructure the dereferenced struct
+match ddl {
+    DdlStatement::CreateExternalTable(ce) => {
+        let CreateExternalTable { name, location, .. } = ce.as_ref();
+        /* ... */
+    }
+}
+```
+
+When you need an owned `CreateExternalTable` / `CreateFunction` out of
+the variant, dereference the box with `*`:
+
+```rust,ignore
+// Before
+match plan {
+    LogicalPlan::Ddl(DdlStatement::CreateExternalTable(cmd)) => Ok(cmd),
+    _ => { /* ... */ }
+}
+
+// After
+match plan {
+    LogicalPlan::Ddl(DdlStatement::CreateExternalTable(cmd)) => Ok(*cmd),
+    _ => { /* ... */ }
+}
+```
+
+See [PR #22733](https://github.com/apache/datafusion/pull/22733) for
+details, including the per-variant size breakdown and benchmark
+results.

Subject: [PATCH 164/878] feat: add max_row_group_bytes option to
 ParquetOptions (#22649)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes https://github.com/apache/datafusion/issues/22650.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

arrow-rs 58.0 added WriterProperties::set_max_row_group_bytes (PR:
apache/arrow-rs#9357
Issue: apache/arrow-rs#1213), which flushes a row group when either the
row-count or the byte limit is reached, whichever comes first, matching
parquet-mr's parquet.block.size. DataFusion already consumes atleast
this version of arrow but does not yet expose this new byte-based setter
through its config.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add `max_row_group_bytes: Option<usize>` (default None) to
ParquetOptions in `datafusion/common/src/config.rs`.
- Wire it through `ParquetOptions::into_writer_properties_builder` to
`WriterPropertiesBuilder::set_max_row_group_bytes`, with a guard that
rejects Some(0) as a configuration error (arrow-rs panics on a zero byte
limit).
- Plumb the field through protobuf serialization - add it to the
ParquetOptions proto message and the proto-common/proto conversions,
with regenerated bindings.
- Exposed as the max_row_group_bytes COPY / CREATE EXTERNAL TABLE format
option alongside max_row_group_size.
- Update the generated config docs and the format options table doc.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes - run locally and passing:

Unit (datafusion-common, parquet_writer.rs):
- defaults to None, so no byte limit is propagated to WriterProperties.
- a configured value propagates to WriterProperties.
- Some(0) is rejected with a configuration error.
- the existing table_parquet_opts_to_writer_props round-trip and
test_defaults_match tests were extended to cover the new field.

Protobuf round-trip (datafusion-proto-common):
- new test_parquet_options_max_row_group_bytes_round_trip confirms the
option survives serialization to protobuf and back.

SLTs:
- new test_files/parquet_max_row_group_bytes.slt writes Parquet with the
option set (via both COPY ... OPTIONS and session config), reads it
back, asserts the data round-trips, and asserts a zero value is
rejected.
- copy.slt exercises the option inside the existing "all supported
statement overrides" COPY test.
- information_schema.slt updated for the new option in SHOW ALL.

Commands run locally (all pass):
cargo test -p datafusion-common --features parquet
cargo test -p datafusion-proto-common
cargo test -p datafusion-proto
cargo test --test sqllogictests -- parquet_max_row_group_bytes
cargo test --test sqllogictests -- information_schema
cargo test --test sqllogictests -- copy

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

Additive only, does not affect existing options.

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Valid values are: plain, plain_dictionary, rle, bit_packed, delta_binary_packed, delta_length_byte_array, delta_byte_array, rle_dictionary, and byte_stream_split. These values are not case sensitive. If NULL, uses default parquet writer setting
 datafusion.execution.parquet.force_filter_selections false (reading) Force the use of RowSelections for filter results, when pushdown_filters is enabled. If false, the reader will automatically choose between a RowSelection and a Bitmap based on the number and pattern of selected rows.
 datafusion.execution.parquet.max_predicate_cache_size NULL (reading) The maximum predicate cache size, in bytes. When `pushdown_filters` is enabled, sets the maximum memory used to cache the results of predicate evaluation between filter evaluation and output generation. Decreasing this value will reduce memory usage, but may increase IO and CPU usage. None means use the default parquet reader setting. 0 means no caching.
-datafusion.execution.parquet.max_row_group_size 1048576 (writing) Target maximum number of rows in each row group (defaults to 1M rows). Writing larger row groups requires more memory to write, but can get better compression and be faster to read.
+datafusion.execution.parquet.max_row_group_bytes NULL (writing) Target maximum size of each row group in bytes. When set, the writer flushes whenever either this limit or `max_row_group_size` is reached, whichever comes first. Useful for bounding writer memory on wide schemas where a row-count limit can map to very different byte sizes. Matches the behavior of `parquet.block.size` in parquet-mr. If `None` (the default), only the row-count limit applies. Currently only honored when `allow_single_file_parallelism` is `false`; by default the parallel file writer ignores this limit.
+datafusion.execution.parquet.max_row_group_size 1048576 (writing) Target maximum number of rows in each row group (defaults to 1M rows). Writing larger row groups requires more memory to write, but can get better compression and be faster to read. When `max_row_group_bytes` is also set, the writer flushes a row group when either limit is reached, whichever comes first.
 datafusion.execution.parquet.maximum_buffered_record_batches_per_stream 2 (writing) By default parallel parquet writer is tuned for minimum memory usage in a streaming execution plan. You may see a performance benefit when writing large parquet files by increasing maximum_parallel_row_group_writers and maximum_buffered_record_batches_per_stream if your system has idle cores and can tolerate additional memory usage. Boosting these values is likely worthwhile when writing out already in-memory data, such as from a cached data frame.
 datafusion.execution.parquet.maximum_parallel_row_group_writers 1 (writing) By default parallel parquet writer is tuned for minimum memory usage in a streaming execution plan. You may see a performance benefit when writing large parquet files by increasing maximum_parallel_row_group_writers and maximum_buffered_record_batches_per_stream if your system has idle cores and can tolerate additional memory usage. Boosting these values is likely worthwhile when writing out already in-memory data, such as from a cached data frame.
 datafusion.execution.parquet.metadata_size_hint 524288 (reading) If specified, the parquet reader will try and fetch the last `size_hint` bytes of the parquet file optimistically. If not specified, two reads are required: One read to fetch the 8-byte parquet footer and another to fetch the metadata length encoded in the footer Default setting to 512 KiB, which should be sufficient for most parquet files, it can reduce one I/O operation per parquet file. If the metadata is larger than the hint, two reads will still be performed.

When set, the writer flushes whenever either this limit or `max_row_group_size` is reached, whichever comes first. Useful for bounding writer memory on wide schemas where a row-count limit can map to very different byte sizes. Matches the behavior of `parquet.block.size` in parquet-mr. If `None` (the default), only the row-count limit applies. Currently only honored when `allow_single_file_parallelism` is `false`; by default the parallel file writer ignores this limit.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

Subject: [PATCH 165/878] feat: implement retract_batch for array_agg(DISTINCT)
 sliding window (#22719)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

### Which issue does this PR close?

  - Closes #22667.

  ### Rationale for this change
  ### What changes are included in this PR?

- DistinctArrayAggAccumulator state: HashSet<ScalarValue> →
HashMap<ScalarValue, u64>.
  - update_batch: increments the per-value count instead of inserting.
- New retract_batch: decrements, removes the key on zero, mirrors the
update_batch null-handling
  rules (ignore_nulls skip, otherwise NULL is a tracked key).
  - supports_retract_batch() now returns true.
- merge_batch is structurally unchanged — the wire state (List<value>)
carries presence, not
multiplicities. Merged counts represent "partitions that emitted this
value," which is fine because
evaluate only reads keys. Refcount semantics are only relied on within a
single accumulator instance
  (window execution, which doesn't merge).
- New helper ScalarValue::size_of_hashmap<V, S> in datafusion-common,
mirroring size_of_hashset.

  ### Are these changes tested?

  Yes

  ### Are there any user-facing changes?

Yes. array_agg(DISTINCT x) now works in bounded/sliding window frames.
Queries that previously
  errored now succeed:

Subject: [PATCH 167/878] Add imdb SQL benchmark (#22680)

## Which issue does this PR close?

Part of #21706

## Rationale for this change

Continue work on sql benchmark migration.

## What changes are included in this PR?

Imdb sql benchmark.

## Are these changes tested?

Yes

`BENCH_NAME=imdb IMDB_FILE_TYPE=csv cargo bench --bench sql`
`BENCH_NAME=imdb IMDB_FILE_TYPE=parquet cargo bench --bench sql`

Note that the IMDB_FILE_TYPE=csv will OOM on most systems because csv
doesn't infer statistics and thus won't get scan predicates and dynamic
filters pushed into DataSourceExec. This results in queries such a 16a
doing joining large tables/intermediates before enough of the selective
filters have reduced the data size to not OOM (tested on a 96GB system).
Setting PARTITION=1 does not solve the issue.

## Are there any user-facing changes?

no

Subject: [PATCH 168/878] Add partitioning compatibility API (#22590)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22589
- EPIC: #22395
- Relevant thread #21992

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Follow-up range partitioning work needs a way to ask whether two
physical partitionings describe the same partition map. This is distinct
from distribution satisfaction and is needed before optimizer rules can
safely use partition-local behavior.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Adds `Partitioning::compatible_with`.
- Adds `RangePartitioning::compatible_with`.
- Adds tests for hash, range, round-robin, and unknown partitioning
compatibility.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes added unit tests for all compatibility

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

Yes. This adds public compatibility helper API on physical partitioning
types.

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 169/878] Add h2o SQL benchmark (#22660)

## Which issue does this PR close?

Part of #21706

## Rationale for this change

Continue work on sql benchmark migration.

## What changes are included in this PR?

h2o sql benchmark

## Are these changes tested?

Yes

`BENCH_NAME=h2o BENCH_SUBGROUP=window H2O_BENCH_SIZE=medium
H2O_FILE_TYPE=parquet cargo bench --bench sql`

I was unable to run the following because of limited memory:

`BENCH_NAME=h2o BENCH_SUBGROUP=groupby H2O_BENCH_SIZE=big
H2O_FILE_TYPE=csv cargo bench --bench sql`
`BENCH_NAME=h2o BENCH_SUBGROUP=groupby H2O_BENCH_SIZE=big

cargo bench --bench sql`
`BENCH_NAME=h2o BENCH_SUBGROUP=join H2O_BENCH_SIZE=big
H2O_FILE_TYPE=parquet cargo bench --bench sql`
`BENCH_NAME=h2o BENCH_SUBGROUP=window H2O_BENCH_SIZE=big
H2O_FILE_TYPE=csv cargo bench --bench sql`
`BENCH_NAME=h2o BENCH_SUBGROUP=window H2O_BENCH_SIZE=big
H2O_FILE_TYPE=parquet cargo bench --bench sql`

## Are there any user-facing changes?

No

Subject: [PATCH 170/878] feat: Add Spark SQL parser dialect config (#22529)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #21653.

## Rationale for this change

This lets users combine Spark-compatible functions with Spark SQL
parsing when they choose the dialect.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

  - Add `Spark` to the SQL parser dialect config enum.
  - Accept `spark` and `sparksql` as dialect config values.
  - Use Spark dialect for Spark sqllogictests.
  - Keep `with_spark_features()` config-neutral.
  - Update dialect docs and expected config output.
- Add tests for Spark dialect parsing and Spark SQL execution with Spark
functions.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

Users can now set `datafusion.sql_parser.dialect` to `spark` or
`sparksql`.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 172/878] fix: handle NULLs in sliding SUM(DISTINCT) window
 frames (#22755)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22754

## Rationale for this change

`SUM(DISTINCT)` over bounded/sliding window frames did not handle `NULL`
values correctly.

It could read values from null slots in the Arrow buffer, and it
returned `0` instead of `NULL` when a frame had no non-null values.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

  - skip `NULL` rows in sliding `SUM(DISTINCT)` update
  - skip `NULL` rows in sliding `SUM(DISTINCT)` retract
  - return `NULL` when the frame has no non-null distinct values
  - reuse the same helper for distinct-value updates during merge
  - add regression tests for accumulator behavior with null slots
- add sqllogictest coverage for sliding window SQL behavior, including
when a frame becomes all `NULL`

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

`SUM(DISTINCT)` over bounded/sliding window frames now handles `NULL`
values correctly:
  - `NULL` inputs are ignored
  - frames with no non-null values return `NULL` instead of `0`
  - No API Change

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 173/878] fix: Scale semi/anti-join column stats by estimated
 row count (#22762)

## Which issue does this PR close?

- Closes #22743

## Rationale for this change

This PR makes several related improvements/fixes to the stats code for
semi- and anti-joins:

1. Scale per-column stats using the estimated output row count, rather
than just reusing the stats from the preserved side of the join.
2. Compute `total_byte_size` for semi/anti-join results, based on
summing per-column `byte_size`, instead of always emitting `Absent`. We
still emit absent for other join types and if any of the per-column
`byte_size` values are `Absent`
3. Pass in the join's `NullEquality` semantics, and use those for stats:
under `NullEqualsNothing`, null join keys will never match (so we can
return `Exact(0)`), whereas under `NullEqualsNull` we consider nulls
just like any other value.

## What changes are included in this PR?

* Stats improvements described above
* Some refactoring and cleanup
* New unit tests
* Update test expectations where needed

## Are these changes tested?

Yes; new tests added.

## Are there any user-facing changes?

Some queries might get different plans.

Subject: [PATCH 174/878] fix: preserve timestamp precision when coercing mixed
 time units (#22759)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22756.

## Rationale for this change

DataFusion coerced Timestamp values with different TimeUnits to the
coarser unit which result in a loss of precision and lead to incorrect
comparison semantics

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

- Change timestamp time unit coercion to prefer the finer unit.
- Add overflow checks for timestamp-to-timestamp casts when converting
to a finer unit.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes. Added unit tests for timestamp coercion and overflow checks, plus
sqllogictest coverage for comparison, subtraction, UNION, and COALESCE.

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

Yes. Timestamp operations with mixed time units now coerce to the finer
unit. If that conversion would overflow i64, the query returns an
overflow error.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 175/878] fix: make
 skip_partial_aggregation_probe_ratio_threshold match the docs (#22752)

## Which issue does this PR close?

- Closes #.

## Rationale for this change

The config `skip_partial_aggregation_probe_ratio_threshold` was
documented as triggering skip when the ratio is **greater than** the
threshold, but the code used `>=`. This meant setting the threshold to
`1.0` (to disable the feature) still skipped rows when cardinality was
exactly 100%.

## What changes are included in this PR?

- Changed `>=` to `>` in the ratio comparison to match the docs.
- Return `None` for `SkipAggregationProbe` when `probe_ratio_threshold
>= 1.0`, effectively disabling the feature since the ratio can never
exceed `1.0`.

## Are these changes tested?

Yes. Added `test_skip_aggregation_disabled_at_threshold_one` which sets
threshold to `1.0` with 100% cardinality input and asserts that no rows
are skipped.

## Are there any user-facing changes?

Yes. Setting `skip_partial_aggregation_probe_ratio_threshold = 1.0` now
reliably disables skip aggregation, matching the documented behavior.

Subject: [PATCH 176/878] test: make ensure_requirements tests deterministic
 (#22789)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22782.

## Rationale for this change

The `ensure_requirements` plan tests were using
`ConfigOptions::default()`.
  That makes `target_partitions` depend on the machine CPU count.

Because of that, the same test could build a different physical plan on
a
runner with more CPUs. In the failing case, `EnsureRequirements` added
an
extra `RepartitionExec`, so the snapshot changed even though the
optimizer was
  doing the right thing.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

  - Add a small test-only config helper with a fixed `target_partitions`
- Use that helper in the `ensure_requirements` test helpers and the
tests in
    this module that directly build a config
- Keep the plan snapshots and idempotency checks stable across machines
with
    different CPU counts

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 177/878] perf: Optimize semi-, anti-join index alignment
 (#22794)

## Which issue does this PR close?

- Closes #22793

## Rationale for this change

`get_semi_indices` computes the duplicate-free intersection between a
`Range` and a `PrimitiveArray` of integer indices (containing probe
matches). The previous algorithm constructs a bitmap from the `Range`
and then probes the bitmap for every element in the range. This does
work linear in the size of the range and also allocates an intermediate
data structure.

We can do better by leveraging the fact that the input index array is
sorted: iterate over the inputs, check membership in the `Range`, and do
duplicate elimination by just comparing with the previous member of the
array. This does work linear in the number of matches and avoids the
intermediate data structure.

We can optimize `get_anti_indices` in a similar manner, except we just
need to emit the in-range gaps between array elements instead of the
array elements themselves.

This improves the performance of `RightSemi` and `RightAnti` joins, as
well as outer joins (since those also call `get_anti_indices`).

Subject: [PATCH 178/878] fix: NestedLoopJoinExec emits spurious unmatched-left
 rows with multiple probe partitions (#22791)

## Problem

`NestedLoopJoinExec` can return incorrect and non deterministic results
for LEFT, RIGHT and FULL joins when the probe side has more than one
partition (the common case for any join whose condition is not a pure
equijoin). Some unmatched left rows are emitted twice: once correctly
and once again as an extra NULL padded row.

## Proof

Correct answer is 5 (every t1 row is unmatched). Verify with
`target_partitions = 1`. With multiple partitions an unpatched build
intermittently returns 6, 7 or 8. Because it is a scheduling race, run
it a few times to observe the divergence.

```sql
set datafusion.execution.target_partitions = 4;
set datafusion.execution.batch_size = 2;

create table t1(v bigint) as values (4),(72),(41),(98),(91);
create table t2(s varchar, w bigint) as values
 ('aaaaaaaaaaaaaaaa', 1),('bbbbbbbbbbbbbbbb', 2),('cccccccccccccccc', 3);

select count(*) as left_join_rows
from t1 left join t2 on (t1.v < t2.w and t2.s <= 'A');
```

## Solution

The probe streams share a `probe_threads_counter`; the stream that
drives it to 0 is the one that emits unmatched left rows, after all
partitions finish probing. In `handle_emit_left_unmatched`, after
`process_left_unmatched` returns `Ok(false)`,
`maybe_flush_ready_batch()` can return early with a ready batch before
the state advances to `Done`. The stream stays in `EmitLeftUnmatched`,
so the next poll re enters `process_left_unmatched` with `left_emit_idx
== 0` and decrements the counter a second time. The counter then reaches
0 before every partition has finished probing, so a partition emits
unmatched left rows early.

The fix decrements the counter at most once per probe stream using a new
`probe_completed_reported` flag (reset per chunk in the memory limited
path). All 42 existing `nested_loop_join` tests pass.

This is separate from #22641, which covers the memory limited spill
fallback path; this bug reproduces with unbounded memory and with
spilling disabled.

Subject: [PATCH 179/878] perf: improve approx_distinct performance 100x when
 there are fewer distinct values with many groups (#22768)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22767

## Rationale for this change

`approx_distinct` is very slow with `GROUP BY` on high-cardinality keys.

On a dataset (~3.9M rows, ~512K groups), one file from the dataset
describe in #22767

```sql
SELECT client_ip, approx_distinct(trace_id) AS cnt
FROM '*.parquet'
GROUP BY client_ip
ORDER BY cnt DESC LIMIT 10;
```

- DataFusion: **~32.6s**
- DuckDB (`approx_count_distinct`): **~0.1s**

The reason is that `approx_distinct` only implemented `Accumulator`, not
`GroupsAccumulator`. So grouped queries fell back to
`GroupsAccumulatorAdapter`, which allocates a full 16 KiB HyperLogLog
per group (~8 GB for 512K groups) and re-slices the input per group on
every batch — even though most groups only see a few distinct values.

## What changes are included in this PR?

- Add a dedicated `GroupsAccumulator` for `approx_distinct` that
processes each batch in a single pass (no per-group slicing or dynamic
dispatch).
- Use an adaptive per-group sketch: keep a small list of hashes (sparse)
and only switch to a dense 16 KiB HyperLogLog after 256 distinct values.
This cuts memory and keeps the partial state small. The dense format
stays compatible with the existing scalar accumulator.
- Add `count_from_hashes` so small groups are estimated directly from
their stored hashes, avoiding a 16 KiB alloc + scan per group at output
time.
- Hashing matches the existing per-type scalar accumulators, so results
are unchanged. Boolean / small-int / `Null` keep using the old path.

Result on the query above: **~32.6s → ~0.12s** (~270x, on par with
DuckDB), with identical output.

## Are these changes tested?

Yes.

- New unit tests for the per-group sketch (sparse/dense, promotion,
serialize/merge round-trip, merging groups, empty groups), checked
against a dense-fold reference.
- New `aggregate.slt` cases: grouped `approx_distinct` over `Utf8`,
`Utf8View`, and `Int32` (small groups are exact), null-only groups (=
0), and a sparse→dense case (2000 distinct/group, within HyperLogLog
error).
- Existing `aggregate.slt` and `aggregate_skip_partial.slt` still pass;
clippy and fmt are clean.

## Are there any user-facing changes?

No API or result changes — only a large speedup for `approx_distinct`
with `GROUP BY` on high-cardinality keys.

Subject: [PATCH 180/878] refactor: Split hash aggregation logic into separated
 streams (#22729)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- part of https://github.com/apache/datafusion/issues/22710
- 1/N of https://github.com/apache/datafusion/pull/22712

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
See issues.

This PR split out partial and final aggregate strem from
`GroupsHashAggregateStream`

To fully migrate hash aggregation, we have to
- Port this optimization back
https://github.com/apache/datafusion/pull/11627
- Support spilling
I think they should be leave to follow up PRs

Todo in this PR:
- [x] Add a temporary configuration `enable_migration_aggregate` to turn
off this path

Since it should be a regression if the above features are not added, it
also helps if to prevent potential regressions from the migration of
other aggregate streams.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
Split out the streams from `GroupsHashAggregateStream`
1. Partial stage of hash aggregation
2. Final stage of hash aggregation

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
3. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

@@ -374,6 +375,7 @@ datafusion.execution.batch_size 8192 Default batch size while creating new batch
 datafusion.execution.coalesce_batches true When set to true, record batches will be examined between each operator and small batches will be coalesced into larger batches. This is helpful when there are highly selective filters or joins that could produce tiny output batches. The target batch size is determined by the configuration setting
 datafusion.execution.collect_statistics true Should DataFusion collect statistics when first creating a table. Has no effect after the table is created. Applies to the default `ListingTableProvider` in DataFusion. Defaults to true.
 datafusion.execution.enable_ansi_mode false Whether to enable ANSI SQL mode. The flag is experimental and relevant only for DataFusion Spark built-in functions When `enable_ansi_mode` is set to `true`, the query engine follows ANSI SQL semantics for expressions, casting, and error handling. This means: - **Strict type coercion rules:** implicit casts between incompatible types are disallowed. - **Standard SQL arithmetic behavior:** operations such as division by zero,   numeric overflow, or invalid casts raise runtime errors rather than returning   `NULL` or adjusted values. - **Consistent ANSI behavior** for string concatenation, comparisons, and `NULL` handling. When `enable_ansi_mode` is `false` (the default), the engine uses a more permissive, non-ANSI mode designed for user convenience and backward compatibility. In this mode: - Implicit casts between types are allowed (e.g., string to integer when possible). - Arithmetic operations are more lenient — for example, `abs()` on the minimum   representable integer value returns the input value instead of raising overflow. - Division by zero or invalid casts may return `NULL` instead of failing. # Default `false` — ANSI SQL mode is disabled by default.
+datafusion.execution.enable_migration_aggregate false Temporary switch for aggregate stream implementations that are being migrated from `GroupedHashAggregateStream`. When set to true, DataFusion tries the migrated implementations when their preconditions are satisfied. When set to false, grouped aggregation falls back to `GroupedHashAggregateStream`. This option will be removed after the migration is finished. See <https://github.com/apache/datafusion/issues/22710> for details.
 datafusion.execution.enable_recursive_ctes true Should DataFusion support recursive CTEs
 datafusion.execution.enforce_batch_size_in_joins false Should DataFusion enforce batch size in joins or not. By default, DataFusion will not enforce batch size in joins. Enforcing batch size in joins can reduce memory usage when joining large tables with a highly-selective join filter, but is also slightly slower.
 datafusion.execution.hash_join_buffering_capacity 0 How many bytes to buffer in the probe side of hash joins while the build side is concurrently being built. Without this, hash joins will wait until the full materialization of the build side before polling the probe side. This is useful in scenarios where the query is not completely CPU bounded, allowing to do some early work concurrently and reducing the latency of the query. Note that when hash join buffering is enabled, the probe side will start eagerly polling data, not giving time for the producer side of dynamic filters to produce any meaningful predicate. Queries with dynamic filters might see performance degradation. Disabled by default, set to a number greater than 0 for enabling it.

Since datafusion writes spill files using the Arrow IPC Stream format, only codecs supported by the Arrow IPC Stream Writer are allowed. Valid values are: uncompressed, lz4_frame, zstd. Note: lz4_frame offers faster (de)compression, but typically results in larger spill files. In contrast, zstd achieves higher compression ratios at the cost of slower (de)compression speed.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

Subject: [PATCH 182/878] fix: Optimize projections in recursive CTEs (#22476)

## Which issue does this PR close?

- Closes #22249.
- Closes #17853.

## Rationale for this change

Optimize projections for the static and recursive terms of recursive
CTEs just like regular subqueries. The previous implementation optimized
projections based on the outer columns, which could cause bugs.

This new implementation still ensures that #16684 remains fixed.

## What changes are included in this PR?

- Updated `optimize_projections` to be applied to the static and
recursive terms of a recursive query.
- Updated and added tests.

## Are these changes tested?

Yes.

## Are there any user-facing changes?

Maybe if the user relied on projections being pushed down from the outer
query to the recursive CTE, but this can be fixed by removing those
unnecessary projections directly in the CTE.

Subject: [PATCH 184/878] fix: Coerce aggregate FILTER predicates to boolean
 (#22774)

## Which issue does this PR close?

- Closes #22773 .

## Rationale for this change

Aggregate and window aggregate `FILTER` clauses currently fail with an
internal error when the filter condition is `NULL`, even though the
equivalent boolean-typed expression (e.g. `CAST(NULL AS BOOLEAN)`) works
correctly.

This occurs because `FILTER` predicates are not being coerced to
`BOOLEAN` during type coercion.

## What changes are included in this PR?

* Coerce aggregate `FILTER` predicates to `BOOLEAN` during type
coercion.
* Apply the same coercion to window aggregate `FILTER` predicates.
* Add SQL logic tests covering `FILTER (WHERE NULL)` for both aggregate
and window aggregate functions.

## Are these changes tested?

Yes.

Added SQL logic tests covering:

* `COUNT(*) FILTER (WHERE NULL)`
* `COUNT(1) FILTER (WHERE NULL)`
* `SUM(1) FILTER (WHERE NULL)`
* `AVG(1) FILTER (WHERE NULL)`
* Window aggregate variants using `FILTER (WHERE NULL)`

## Are there any user-facing changes?

Yes.

Queries using `FILTER (WHERE NULL)` no longer fail with an internal
error and now return the expected results. Also, no changes were made to
any public APIs

Subject: [PATCH 186/878] feat: add array_sum scalar function (#22542)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Partial of #21536 — `array_sum` (first of the array aggregates in the
series).

## Rationale for this change

Continues the per-function split sequence requested by @alamb on #21536.
Four sibling PRs already merged: `cosine_distance` (#21542),
`inner_product` (#21861), `array_normalize` (#22013), `array_scale`
(#22466). `array_add` is in flight as #22459 by @SubhamSinghal.

`array_sum` is the first of the three array-aggregate functions (sum,
product, avg). Its semantics set the pattern for the other two
aggregates.

## What changes are included in this PR?

- New scalar UDF `array_sum(array)` in
`datafusion/functions-nested/src/array_sum.rs`
- Module wire-up + registration in
`datafusion/functions-nested/src/lib.rs`
- SLT tests at `datafusion/sqllogictest/test_files/array_sum.slt`
- Auto-generated docs entry in
`docs/source/user-guide/sql/scalar_functions.md`

**Signature:** \`List/LargeList/FixedSizeList<numeric>\` in, \`Float64\`
out (one scalar per row). Numeric inner types coerced to \`Float64\`.

**NULL semantics — SQL aggregate convention (deliberate divergence from
binary-op siblings):**
- NULL row → NULL row out
- NULL elements are **skipped**, matching PostgreSQL \`array_sum\`,
DuckDB \`list_sum\`, Spark \`aggregate\`. Binary-op siblings
(\`inner_product\`, \`array_normalize\`) null-row on NULL element
because their per-element operation is undefined on NULL; aggregates
conventionally skip NULLs in SQL.
- All-NULL row → NULL out (matches \`SUM(...)\` over an all-NULL column)

- **Empty array → NULL** (matches sibling `array_product` #22703,
PostgreSQL, DuckDB `list_sum`, SQL Standard SUM-of-empty-set)

**Alias:** \`list_sum\` (matches the precedent of
\`array_normalize\`→\`list_normalize\`, \`array_scale\`→\`list_scale\`).

## Are these changes tested?

Yes. SLT covers happy paths, empty arrays, NULL row, NULL elements (mix
+ all-NULL), all list variants (List/LargeList/FixedSizeList), numeric
coercion (Float32/Int64/integer literals), multi-row composition, error
paths, return type, and the \`list_sum\` alias.

## Are there any user-facing changes?

Yes — new SQL scalar function \`array_sum(array)\` and its alias
\`list_sum\`.

Subject: [PATCH 187/878] coerce Union vs scalar in comparisons (#22825)

- Closes https://github.com/apache/datafusion/issues/18825

Add a `union_coercion` rule so that comparisons between a Union column
and an opaque scalar pick the scalar type whenever any union variant can
be cast to it. The execution side is already handled by arrow-rs's
`cast(Union -> T)` (arrow 58.3.0+), which extracts values from the
matching variant and emits NULL for rows whose active variant is not
castable to the target

+tests for union type comparison coercion.
+
+when comparing a union type with an "opaque" (non-union) scalar type, the
+coercion rule picks the scalar type if any union variant can be cast to it.
+the actual extraction at execution time is delegated to arrow's
+`cast(Union -> T)`, which selects the source variant using three passes:
+
+1. exact match: a variant whose type equals the target
+2. same type family: e.g. Utf8 / LargeUtf8 / Utf8View are interchangeable,
+   so Utf8 is preferred over Int32 when the target is Utf8View
+3. castable: the first variant (by type_id order) where can_cast_types is true
+
+rows whose active variant is not the selected one become NULL.
+
+current limitations exercised by these tests:
+- numeric literals default to Int64, so a comparison against `42` won't pick
+  the Int32 variant exactly
+- when multiple variants are equally good in pass 3, the smaller type_id wins

Subject: [PATCH 188/878] bench: add predicate_eval SQL micro-benchmark suite
 for conjunctive filter evaluation (#22704)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!-- No tracking issue; this is a standalone benchmark contribution. -->

This PR does not close an issue. It adds a benchmark suite to support
work and
discussion around predicate ordering in filter evaluation (e.g. the
static
reordering in #22343 and the runtime/statistics-based reordering
explored in
#22698). It deliberately benchmarks *no specific implementation* — see
below.

## Rationale for this change

Conjunctive (`AND`) filter evaluation in `FilterExec` is a left-deep
`BinaryExpr(And)` chain, and the order conjuncts are evaluated in can
change
runtime by large factors: once a leading conjunct passes few enough rows
the
batch is physically compacted before the rest, so a cheap-and-selective
predicate evaluated early saves later predicates work. Predicate
ordering is
therefore an active area (static heuristics, runtime/adaptive schemes,
cost
models).

There is currently no benchmark suite that isolates the dimensions that
drive
this. Existing macro-benchmarks (TPC-H/DS, ClickBench) only incidentally
exercise filter ordering, so they can't show *why* a change to ordering
helped
or hurt, or guard the order-insensitive case against regressions.

## What changes are included in this PR?

A new SQL benchmark suite, `benchmarks/sql_benchmarks/predicate_eval`,
built on
the existing `.benchmark` template framework (no engine code, no new
Rust). It
sets no engine config of its own and measures DataFusion's built-in
short-circuit
by default; a system under test is toggled purely via its native
`DATAFUSION_EXECUTION_*` env var (the bench harness builds its
`SessionContext`
with `SessionConfig::from_env`), so the same scenarios can characterise
the
baseline, a static heuristic, an adaptive scheme, or a cost model and be
compared apples-to-apples.

It is organised into 10 subgroups (select with `BENCH_SUBGROUP`), each
varying
one property of conjunctive filter evaluation while holding the others
fixed:

| Subgroup | What it varies (others held fixed) |
|---|---|
| `costsel` | cost and selectivity point in different directions
(expensive predicate is the selective one) |
| `cost` | per-predicate cost, at equal selectivity |
| `selectivity` | per-predicate selectivity, at equal cost |
| `cardinality` | conjunct count `k = 2/4/8/16` |
| `width` | string-column width (`PRED_FILL` = 2 / 30 / 170 chars) |
| `scale` | row count `5k / 100k / 5M / 50M` |
| `neutral` | predicates are interchangeable (equal cost, none
selective) — an order-insensitive control |
| `correlation` | conditional vs marginal selectivity (independent /
positively / anti-correlated) |
| `drift` | selectivity that changes across the scan |
| `nulls` | null density (two- vs three-valued predicate results) |

Each query's comment notes the per-predicate cost/selectivity that the
data
generation hides from the SQL. Data is synthetic and generated inline by
each
subgroup's load SQL (no external files); `PRED_ROWS` sizes it and
`PRED_FILL`
sets string width. Wired into `bench.sh` (`./bench.sh run
predicate_eval`) and
documented in `benchmarks/sql_benchmarks/README.md`.

The design was informed by surveying how Velox drives the analogous
decision
(it ranks by cycles-per-row-eliminated, `time / (rows_in - rows_out)`).

> Note: the `scale` subgroup's `q52`/`q53` build 5M / 50M-row tables
(the latter
> ~9 GB); run a single point with `BENCH_QUERY` if that is too heavy.

## Are these changes tested?

These are benchmark definitions, not engine code. Each `.benchmark`
includes an
`assert` that the generated table is non-empty, and every subgroup was
run
locally at small `PRED_ROWS` to confirm the suite parses, loads,
asserts, and
executes end-to-end. The queries are order-invariant (`SELECT count(*)
...`), so
any predicate-ordering system can also be checked for correctness by
diffing
counts with the optimization on vs. off.

## Are there any user-facing changes?

No. This only adds an opt-in benchmark suite and its documentation; no
public
API, engine behavior, or default configuration changes.

+description = "Micro-benchmarks for conjunctive (AND) filter evaluation. Each subgroup exercises a different predicate pattern (per-predicate cost, selectivity, conjunct count, string-column width, row count, correlation, selectivity drift, plus an order-neutral control) so the suite can show how an adaptive predicate-ordering system behaves across them -- the kind of change these benchmarks are meant to help drive, e.g. https://github.com/apache/datafusion/issues/11262. By default it measures DataFusion's built-in left-deep AND short-circuit and sets no engine config of its own; toggle a system under test with its native DATAFUSION_* env var (the harness reads SessionConfig::from_env), e.g. DATAFUSION_EXECUTION_ADAPTIVE_FILTER_REORDERING=true. Subgroups (BENCH_SUBGROUP): costsel, cost, selectivity, cardinality, width, scale, neutral, correlation, drift. Size synthetic data with PRED_ROWS and string-column width with PRED_FILL."

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Figured this out when working through the codebase, I think it worth
some more comment.

```bash
cd datafusion-examples/examples
cargo run --example data_io -- partitioned_file_schema
```

## Are there any user-facing changes?

No user facing changes.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

Subject: [PATCH 191/878] bench: make wide_schema honor DATA_DIR like the other
 sql_benchmarks (#22836)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Relates to #21968 (wide-schema benchmark work).

## Rationale for this change

Every `sql_benchmarks` suite declares its external-table `LOCATION` as
`${DATA_DIR:-data}/...`, and the matching `bench.sh run_*` forwards
`DATA_DIR="${DATA_DIR}"` to the benchmark process — e.g. `clickbench`,
`imdb`, `tpch`, `push_down_topk`, `h2o` all do this.

`wide_schema` (added in #21970) diverged on **both** counts:
- `wide_schema/init/load.sql` hardcoded `LOCATION
'data/wide_schema/...'` (no `${DATA_DIR}`)
- `run_wide_schema` did not forward `DATA_DIR`

Run from inside the repo this happens to work, because the process CWD
is the repo's `benchmarks/` and the relative `data/` path resolves. But
it breaks whenever the data directory is not under the current directory
— for example the CI benchmark runner builds/runs the benchmark from a
separate source checkout while staging the dataset elsewhere and
pointing at it via `DATA_DIR`. There, wide_schema fails at load:

```
initialization failed: No files found at file:///.../benchmarks/data/wide_schema/wide/.
Cannot infer schema from an empty location; either add data files or declare an explicit schema for the table.
```

(The `bench.sh` variable `DATA_DIR` is set but not exported, so it only
reaches the benchmark when a `run_*` function passes it explicitly —
which `run_tpch` etc. do and `run_wide_schema` did not.)

## What changes are included in this PR?

Two one-line fixes bringing `wide_schema` in line with the convention
used by every other suite:
- `load.sql`: `data/wide_schema/...` →
`${DATA_DIR:-data}/wide_schema/...`
- `run_wide_schema`: forward `DATA_DIR="${DATA_DIR}"` for both the
`wide` and `narrow` subgroups

## Are these changes tested?

Benchmark tooling only. The substitution path is the same one every
other suite already relies on: the SQL harness's `process_replacements`
resolves `${DATA_DIR:-data}` from the env (falling back to `data`), and
`run_wide_schema` now forwards `DATA_DIR` exactly as `run_tpch` does.
Verified `bench.sh` still parses (`bash -n`). Default in-repo behavior
is unchanged (CWD-relative `data/`).

## Are there any user-facing changes?

No. Benchmark harness only.

Subject: [PATCH 192/878] fix: approx_distinct over-counts for utf8view
 (#22815)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes https://github.com/apache/datafusion/issues/22796

## Rationale for this change

`approx_distinct` over-counted distinct values for `Utf8View` columns
when the same short string appeared across batches with different
layouts.

Arrow stores strings ≤ 12 bytes inline in the 128-bit view integer. The
fast path (no data buffers) hashed these as raw `u128`. But when a batch
also had a long string, it fell into a different branch that hashed
**all** strings as `&str` — including the short inline ones. The same
string hashed differently in different batches, so HyperLogLog counted
it twice.

## What changes are included in this PR?

- **`StringViewHLLAccumulator::update_batch`** and **`Utf8ViewHasher`**:
in mixed batches (data buffers present), short strings (≤ 12 bytes) are
still hashed as the raw `u128` view; only long strings hash as `&str`.
This keeps hashing consistent regardless of batch layout.

- **Two regression tests**:
- `utf8view_acc_split_batches_match_single_mixed_batch` — scalar
accumulator
- `utf8view_groups_short_string_hashed_consistently_across_batches` —
group accumulator

## Are these changes tested?

Yes, two new regression tests cover the exact failure mode.

## Are there any user-facing changes?

Yes. `approx_distinct` on `Utf8View` / `VARCHAR VIEW` columns now
returns correct (lower) counts. Results may differ from the previously
incorrect values.

Subject: [PATCH 193/878] refactor: Port CaseExpr proto serialization hooks
 (#22838)

## Which issue does this PR close?

- Closes #22421.

## Rationale for this change

CaseExpr should own its protobuf serialization and deserialization
through the PhysicalExpr try_to_proto / try_from_proto hooks, matching
the migration pattern used by other physical expressions and avoiding
the central downcast chain.

## What changes are included in this PR?

- Adds CaseExpr::try_to_proto in the PhysicalExpr impl.
- Adds CaseExpr::try_from_proto as an inherent proto constructor.
- Routes physical expression decoding for CaseExpr through the new hook.
- Removes the old CaseExpr serialization arm and its helper from
datafusion-proto.
- Adds direct hook tests covering encode, decode, wrong node variant,
missing when/then children, and child encode/decode error propagation.

## Are these changes tested?

Yes:

- cargo fmt --all
- cargo test -p datafusion-physical-expr --features proto
case::tests::try_
- cargo test -p datafusion-proto --test proto_integration
- cargo clippy -p datafusion-physical-expr --features proto --tests --
-D warnings
- cargo clippy -p datafusion-proto --test proto_integration -- -D
warnings

## Are there any user-facing changes?

No. This is an internal proto serialization refactor with the same wire
format.

<a

</ul>
<h2>4.35.5 - 15 May 2026</h2>
<ul>
<li>We have improved how the JavaScript bundles for the CodeQL Action
are generated to avoid duplication across bundles and reduce the size of
the repository by around 70%. This should have no effect on the runtime
behaviour of the CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3899">#3899</a></li>
<li>For performance and accuracy reasons, <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> will now only be enabled on a pull request when
diff-informed analysis is also enabled for that run. If diff-informed
analysis is unavailable (for example, because the PR diff ranges could
not be computed), the action will fall back to a full analysis. <a
href="https://redirect.github.com/github/codeql-action/pull/3791">#3791</a></li>
<li>If multiple inputs are provided for the GitHub-internal
<code>analysis-kinds</code> input, only <code>code-scanning</code> will
be enabled. The <code>analysis-kinds</code> input is experimental, for
GitHub-internal use only, and may change without notice at any time. <a
href="https://redirect.github.com/github/codeql-action/pull/3892">#3892</a></li>
<li>Added an experimental change which, when running a Code Scanning
analysis for a PR with <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> enabled, prefers CodeQL CLI versions that have
a cached overlay-base database for the configured languages. This speeds
up analysis for a repository when there is not yet a cached overlay-base
database for the latest CLI version. We expect to roll this change out
to everyone in May. <a
href="https://redirect.github.com/github/codeql-action/pull/3880">#3880</a></li>
</ul>
<h2>4.35.4 - 07 May 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.4">2.25.4</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3881">#3881</a></li>
</ul>
<h2>4.35.3 - 01 May 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.19.3 and earlier. These versions of
CodeQL were discontinued on 9 April 2026 alongside GitHub Enterprise
Server 3.15, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3837">#3837</a></li>
<li>Configurations for private registries that use Cloudsmith or GCP
OIDC are now accepted. <a
href="https://redirect.github.com/github/codeql-action/pull/3850">#3850</a></li>
<li>Best-effort connection tests for private registries now use
<code>GET</code> requests instead of <code>HEAD</code> for better
compatibility with various registry implementations. For NuGet feeds,
the test is now always performed against the service index. <a
href="https://redirect.github.com/github/codeql-action/pull/3853">#3853</a></li>
<li>Fixed a bug where two diagnostics produced within the same
millisecond could overwrite each other on disk, causing one of them to
be lost. <a
href="https://redirect.github.com/github/codeql-action/pull/3852">#3852</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.3">2.25.3</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3865">#3865</a></li>
</ul>
<h2>4.35.2 - 15 Apr 2026</h2>
<ul>
<li>The undocumented TRAP cache cleanup feature that could be enabled
using the <code>CODEQL_ACTION_CLEANUP_TRAP_CACHES</code> environment
variable is deprecated and will be removed in May 2026. If you are
affected by this, we recommend disabling TRAP caching by passing the
<code>trap-caching: false</code> input to the <code>init</code> Action.
<a
href="https://redirect.github.com/github/codeql-action/pull/3795">#3795</a></li>
<li>The Git version 2.36.0 requirement for improved incremental analysis
now only applies to repositories that contain submodules. <a
href="https://redirect.github.com/github/codeql-action/pull/3789">#3789</a></li>
<li>Python analysis on GHES no longer extracts the standard library,
relying instead on models of the standard library. This should result in
significantly faster extraction and analysis times, while the effect on
alerts should be minimal. <a
href="https://redirect.github.com/github/codeql-action/pull/3794">#3794</a></li>
<li>Fixed a bug in the validation of OIDC configurations for private
registries that was added in CodeQL Action 4.33.0 / 3.33.0. <a
href="https://redirect.github.com/github/codeql-action/pull/3807">#3807</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.2">2.25.2</a>.

Writing larger row groups requires more memory to write, but can get better compression and be faster to read. When `max_row_group_bytes` is also set, the writer flushes a row group when either limit is reached, whichever comes first.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  |
 | datafusion.execution.parquet.max_row_group_bytes                        | NULL                      | (writing) Target maximum size of each row group in bytes. When set, the writer flushes whenever either this limit or `max_row_group_size` is reached, whichever comes first. Useful for bounding writer memory on wide schemas where a row-count limit can map to very different byte sizes. Matches the behavior of `parquet.block.size` in parquet-mr. If `None` (the default), only the row-count limit applies. Currently only honored when `allow_single_file_parallelism` is `false`; by default the parallel file writer ignores this limit.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

Subject: [PATCH 204/878] fix: regex simplification of anchored patterns
 produces wrong results (#22727)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22726.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

The regex simplification rule rewrites anchored regex matches
(`^literal$`, `^(a|b)$`) into cheaper `=` / `IN` / `LIKE` expressions.
Two bugs in that path:

1. The literal was always built as `Utf8` via `lit(...)`, so on a
`Utf8View` / `LargeUtf8` column the rewritten comparison failed at
execution with `Invalid comparison operation: Utf8View == Utf8`.
2. A `~*` (case-insensitive) anchored literal was rewritten to a
case-sensitive `=`, silently dropping rows that differ only in case.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Build the extracted literal with `string_scalar.to_expr(...)` so its
type follows the column type (`Utf8` / `LargeUtf8` / `Utf8View`),
consistent with the existing `LIKE` branches.
- Rewrite `~*` anchored literals to `ILIKE` instead of `=`. The existing
`is_safe_for_like` guard ensures the literal has no `%` / `_`, so this
is an exact case-insensitive match. (Anchored alternations under `~*`
still fall back to regex evaluation.)

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes. `predicates.slt` now covers anchored `~` / `~*`, single literals
and alternations, over both `Utf8` and `Utf8View` columns. Existing
`regex.rs` unit tests still pass.

## Are there any user-facing changes?

Yes, bug fixes only

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

- Closes #22490
- Closes #11108

## Rationale for this change

SQL (per PG and IEEE 754) treats `+0.0` and `-0.0` as equal in `=`, `IS
DISTINCT FROM`, DISTINCT, GROUP BY, UNION/INTERSECT/EXCEPT, equi-joins,
and `array_*` set ops. DataFusion treated them as
  distinct because:

- Arrow's `cmp::eq`/`gt`/`lt` use IEEE 754 totalOrder for floats —
`arrow-ord-58.3.0/src/cmp.rs:71-75` explicitly says *"please normalize
zeros before calling this kernel"*.
- Arrow's `RowConverter` row-encodes floats with totalOrder; ±0 produce
different bytes.
- DataFusion's primitive float hashing used raw `to_bits()` /
`to_ne_bytes()`, so ±0 hashed to different buckets.

  ## What changes are included in this PR?

  **Helper** in `datafusion/common/src/utils/mod.rs`:
- `normalize_float_zero(&ArrayRef) -> ArrayRef` — rewrites `-0.0 → +0.0`
for Float16/32/64 via `PrimitiveArray::unary`; `Arc::clone` for
non-float. NaN payloads preserved (`bits << 1 == 0` matches only
  ±0).
- `normalize_float_zero_scalar(ScalarValue) -> ScalarValue` — symmetric
for scalars.

**Applied at six boundary sites** where DataFusion hands float data to
Arrow:
  | Site | Fixes |
  |---|---|
| `physical-expr-common/src/datum.rs::apply_cmp` | BinaryExpr `=`, `<`,
`>`, `IS DISTINCT FROM` |
| `physical-plan/src/joins/utils.rs::eq_dyn_null` | HashJoin row
equality → INNER JOIN, INTERSECT, EXCEPT |
| `physical-plan/src/aggregates/group_values/row.rs::intern` |
Multi-column row-encoded GROUP BY |
| `functions-nested/src/set_ops.rs::general_array_distinct` |
`array_distinct` |
| `functions-nested/src/set_ops.rs::generic_set_lists` | `array_union`,
`array_intersect` |
  | `functions-nested/src/except.rs::general_except` | `array_except` |

  **Float hash macros** normalize for consistency:
- `datafusion/common/src/hash_utils.rs::hash_float_value!` —
`create_hashes`, hash joins, shuffle.
-
`datafusion/physical-plan/src/aggregates/group_values/single_group_by/primitive.rs::hash_float!`
— single-column primitive GROUP BY fast path.

**Single-column primitive GROUP BY / DISTINCT**
(`GroupValuesPrimitive::intern`,
`PrimitiveGroupValueBuilder::{append_val,vectorized_append,equal_to,vectorized_equal_to_*}`)
canonicalize the input via
a new default-identity `canonicalize` method on the local `HashValue`
trait (float override only). Trait visibility lifted to `pub` so the
multi-column file can use it.

+## Negative Zero (-0.0) vs. Positive Zero (+0.0) Behavior
+##########
+#
+# IEEE 754 specifies +0.0 == -0.0 (they compare equal). PostgreSQL follows
+# this and treats them as the same value for DISTINCT, GROUP BY, UNION,
+# INTERSECT, EXCEPT, and equality predicates. The bit patterns differ in
+# the sign bit, so any code path that hashes / compares the raw bits (e.g.
+# `f64::to_bits` or `f64::to_ne_bytes`) will treat them as distinct values
+# and must be normalized before grouping / dedup.
+#
+# Note: the sqllogictest formatter renders both `-0.0` and `+0.0` as `0`,
+# so the visible scalar values look identical in the expected output. The
+# behavior is asserted via row counts and via auxiliary `1.0 / a`
+# (`Infinity` vs `-Infinity`) columns that expose the sign.

Subject: [PATCH 206/878] docs: link release tracking issue to release
 management page (#22822)

## Which issue does this PR close?

- Part of  https://github.com/apache/datafusion/issues/22765
- Related to https://github.com/apache/datafusion/issues/19783.


## Rationale for this change

While reviewing https://github.com/apache/datafusion/pull/22766 from
@comphead I noticed that the release management guide did not point
contributors to the ongoing release tracking issue, where planned
releases are listed.

## What changes are included in this PR?

This PR adds a link to the DataFusion Releases tracking issue from the
release management guide and clarifies that each release is coordinated
in a dedicated GitHub issue.

## Are these changes tested?

Not run. This is a documentation-only change.

## Are there any user-facing changes?

No API or behavior changes. This updates contributor documentation only.

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22765 .

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

+## Backport Criteria
+
+A release branch is a stabilization branch for an imminent or recent patch
+release. The bar for landing a change on a release branch is therefore
+_higher_ than the bar for landing on `main`, not lower. These criteria define
+what is eligible for backport; the [Backport Workflow](#backport-workflow)
+below describes the mechanics.
+
+DataFusion follows Cargo SemVer, with breaking changes allowed at major
+version boundaries — see the [API health policy] for the full framing of
+public Rust and SQL API stability. Patch releases (`x.y.z`, `z ≥ 1`) carry
+fixes only and never introduce new features or breaking changes.
+
+### Eligible for backport
+
+- **Security fixes.** Fixes for known or reported security issues should be
+  backported to every actively maintained release branch.
+- **Correctness fixes.** Fixes for queries that produce incorrect results,
+  panics, data loss, or crashes. If the fix itself changes user-visible SQL
+  semantics to make a wrong result right, follow [Behavior changes] below.
+- **Stability and regression fixes.** Fixes for regressions introduced in the
+  current release line, hangs, deadlocks, memory leaks, or other availability
+  issues.
+- **Build, CI, and test fixes** required to keep the branch buildable and
+  releasable.
+- **Documentation fixes** for behavior already in the release. Documentation
+  for behavior that exists only on `main` does not belong on a release branch.
+
+### Not recommended for backport
+
+- **New features**, including new SQL functions, new optimizer rules, new
+  configuration options, new public APIs, and new file-format support. Land
+  on `main` and ship in the next major release.
+- **Breaking API changes** of any kind, Rust or SQL. DataFusion makes
+  breaking changes only at major version boundaries — see [API health policy].
+- **Refactors and cleanup** that do not fix a bug, even if they are correct.
+- **Performance improvements** that are not also correctness or stability
+  fixes. Land on `main`.
+- **Dependency upgrades**, except when the upgrade itself is the security or
+  correctness fix and there is no narrower alternative.
+
+### Behavior changes
+
+A "behavior change" is any fix that alters user-visible results: SQL
+semantics (values, ordering, types, null handling), error messages that
+downstream users may rely on, plan output, or default configuration values.
+
+Behavior-changing fixes need extra scrutiny on a release branch because
+users upgrading between patch versions do not expect their queries to start
+returning different results. When proposing one for backport, state on the
+release tracking issue _why_ the change should ship in this patch release
+rather than wait for the next major. The previous and new behavior should
+already be documented on the original issue or PR — link to that rather
+than restating it.
+
+If in doubt, default to "land on `main`, ship in the next major."
+
+### Who decides
+
+The release manager for the active release line is the final reviewer of
+what goes into the patch release. They coordinate via the release tracking
+issue (for example, the [release issue for 50.3.0]). Anyone may propose a
+backport by opening a backport PR and linking it from the tracking issue;

+### Active release branches
+
+DataFusion does not maintain Long-Term Support branches. In general only the
+most recent `branch-NN` is actively maintained for backports, but if you need
+fixes in older releases, we are open to discussion.
+
+Security fixes are an exception: a maintainer may choose to backport a
+critical security fix to an older branch even after it would otherwise be
+closed. Discuss on the dev list or in a tracking issue before doing so.

Subject: [PATCH 209/878] refactor(hash-aggr): Forward port the soft limit
 optimization to the new hash aggregation impl (#22824)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- part of https://github.com/apache/datafusion/issues/22710

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Part of rewriting hash aggregation into several dedicated streams.

In the first step https://github.com/apache/datafusion/pull/22729,
`PartialHashAggregateStream` and `FinalHashAggregateStream` has been
split from the old `GroupsHashAggregateStream`, but both stream only
have basic implementation, no optimizations and extra features like
spilling.
\* it's incremental migration, so old impl won't change, we plan to
delete it once migration is finished

This PR forward ports the below optimization to the new implementation:
- https://github.com/apache/datafusion/pull/8038

The optimizer part don't have to move, ported changes are only inside
aggregate operator.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
Extends `PartialHashAggregateStream` and `FinalHashAggregateStream` to
apply the optimization. See code comment at
`datafusion/physical-plan/src/aggregates/hash_aggregate.rs` for the
background.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Yes, the original test in https://github.com/apache/datafusion/pull/8038
is only at `ExecutionPlan` level, they're still passing after the
change.
This PR added new test coverage: check `explain analyze` to ensure the
implementation actually respects this soft limit at runtime.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 210/878] feat: Add From<Option<T>> trait for Precision enum
 (#22792)

This commit adds a `From<Option<T>>` trait for `Precision`. Porting from
`influxdb` to upstream:

Subject: [PATCH 211/878] Add logical range partitioning representation
 (#22777)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22778.
- Related: #21992, #22395.
- Needed by #22657.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Declared scan output partitioning should use logical partitioning
metadata, not physical partitioning types. This adds logical range
partitioning so range-partitioned sources can declare their layout at
the logical layer.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add logical `Partitioning::Range` and `RangePartitioning`.
- Move `SplitPoint` and shared split-point validation to
`datafusion-common`.
- Wire logical range partitioning through expression traversal,
rewrites, and display.
- Keep planning, logical proto, and Substrait support explicitly
unsupported for now.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes. Unit tests added

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

Yes. This adds public logical range partitioning API. No breaking API
changes.

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 212/878] refactor(physical-plan): extract make_group_column
 factory + eager init at try_new + tighten Time variants (#22751)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Which issue does this PR close?

PR 1 of 5 from the split agreed on
https://github.com/apache/datafusion/pull/22706#issuecomment-4602892722.
Related to #22682 / #22715 (full `GroupValuesColumn` type coverage).
Lays the dispatcher foundation; closes nothing on its own.

# Rationale for this change

Preparation for the nested-type `GroupColumn` work. No new builders
here. The goal is to refactor the per-field builder dispatch in
`GroupValuesColumn` so subsequent PRs that add `FixedSizeList` /
`Struct` / `List` / `LargeList` support can plug into one well-defined
factory instead of growing the inline match in
`GroupValuesColumn::intern`. Also includes two adjacent correctness
fixes around the `Time32` / `Time64` variants that came up in the
upstream thread.

# What changes are included in this PR

1. **Factory extraction.** The inline match that maps each schema field
to a `Box<dyn GroupColumn>` builder moves out of
`GroupValuesColumn::intern` into a free function
`make_group_column(field: &Field) -> Result<Box<dyn GroupColumn>>`.
Subsequent nested-type specializations can recursively call this factory
for child field construction without enumerating every combination
inline.

2. **Eager construction at `try_new`.** Per @2010YOUY01's review, the
per-field builder vector is now built in the constructor via a private
`build_group_columns` helper. `emit(EmitTo::All)` uses `mem::replace` to
swap in a fresh vector after draining the old one; `clear_shrink`
rebuilds the same way. The post-condition `self.group_values.len() ==
self.schema.fields().len()` holds across the aggregator's lifetime, so
`intern` no longer carries a lazy-init branch. Unsupported schemas now
fail fast at `try_new` rather than at the first `intern` call. In
production this changes nothing because `new_group_values` in
`aggregates/group_values/mod.rs` only calls `GroupValuesColumn::try_new`
after `multi_group_by::supported_schema` returns true.

3. **`Time32` / `Time64` `supported_type` alignment.** Previously
`supported_type` matched `Time32(_)` (admitting the invalid Microsecond
/ Nanosecond combinations) and did not match `Time64(_)` at all, while
the dispatcher accepted `Time32(Second / Millisecond)` and
`Time64(Microsecond / Nanosecond)`. Tighten `supported_type` to the
exact set the dispatcher constructs. The dispatcher's wildcard arms for
invalid `Time` variants now return `not_impl_err` instead of silently
producing an empty builder vector.

4. **`supported_type` ↔ `make_group_column` consistency fuzz.** New unit
test `supported_type_and_make_group_column_stay_in_sync` iterates a
representative set of 20 supported and 6 unsupported `DataType` values
and asserts the biconditional. Pins the alignment so future contributors
who add a type to one side without the other trip a unit test
immediately.

# What this PR is NOT doing

- No new `GroupColumn` builders. `FixedSizeList`, `Struct`, `List`,
`LargeList` come in subsequent PRs of the #22682 sequence.
- No new types in `supported_type`'s allow-list (the `Time` tightening
removes invalid combinations rather than adding new ones).
- No external dependencies. Per @alamb's review the earlier `dhat-heap`
feature and the `dhat` dependency were dropped; memory savings in
follow-up PRs will be measured via `GroupColumn::size()` head-to-head
against `GroupValuesRows`, matching the existing
`column_path_uses_less_memory_than_rows_for_*` tests pattern in #22706.

# Are these changes tested

- `cargo test -p datafusion-physical-plan --lib
aggregates::group_values`: 30 tests pass (27 existing + 3 new: the
consistency fuzz, the mixed-schema rejection, and the `try_new`-time
NotImpl propagation).
- `cargo test -p datafusion-physical-plan --lib aggregates`: 105 tests
pass (no regression in the broader aggregate suite).
- `cargo clippy -p datafusion-physical-plan --lib --tests -- -D
warnings`: clean.
- `cargo fmt --check`: clean.

# Are there any user-facing changes

No semantic change for any schema that already used `GroupValuesColumn`
on main. The factory is the same dispatch logic pulled into a function;
the `Time` changes only affect schemas that are semantically invalid
Arrow types anyway; the eager construction surfaces `not_impl_err` from
a different call site for those defensive paths.

Subject: [PATCH 213/878] refactor: centralize SQL dialect metadata (#22840)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22818.

## Rationale for this change

DataFusion kept SQL dialect metadata in several separate places, which
made it easy for enum variants, canonical names, aliases, display names,
docs, and error messages to drift.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

  - Centralize dialect metadata in one macro-driven source.
- Generate the `Dialect` enum, metadata table, canonical names, aliases,
display names, and available-dialect string from that source.
  - Replace `Dialect::AVAILABLE` with `Dialect::available()`.
  - Add `Dialect::metadata()` for iterating supported dialects.
- Update dialect error messages and generated config docs to use the
centralized metadata.
  - Add an upgrade note for the removed public constant.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

Yes. `Dialect::AVAILABLE` is removed and replaced by
`Dialect::available()`.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

-tightens its allocator-level bank to `N * 1.10` (10% headroom). If the test
-allocates more than that — including bytes DataFusion's tracker didn't see
-— the test panics with an `OverdraftPanic` reporting the actual balance at
-panic time. SLTs without a `SET` of `memory_limit` see no change in
-behavior; the bank stays loose and `SHOW ALL` continues to render the limit
-as `unlimited`.
-
-Inside the runner each file gets its own multi-thread Tokio runtime so
-context-ids stamped onto worker threads stay stable for the allocator
-hook, and per-file accounts in the bank are isolated from each other.

-//! Allocator-driven memory accounting with per-context budgets.
-//!
-//! The bank ([`ACCOUNTS`]) holds one [`AtomicIsize`] account per stamped
-//! `CONTEXT_ID`, each tracking its own remaining budget. Allocations debit
-//! the current thread's account, deallocations credit it; below zero is an
-//! overdraft. Threads with `CONTEXT_ID == 0` (main, the outer orchestration
-//! runtime, blocking-pool hosts) are untracked and skip the hot path.
-//!
-//! Per-alloc bookkeeping accumulates in a thread-local `LOCAL_BALANCE`
-//! drift counter; it settles into the account once `|drift|` crosses
-//! [`SETTLE_THRESHOLD`] (64 KB), amortizing the `RwLock` read + atomic
-//! op across thousands of allocations.
-//!
-//! [`account_balance`] reads the current thread's account; it lags reality
-//! by up to one threshold's worth of un-settled drift per thread.
-//!
-//! # Enforcement
-//!
-//! An allocation that drives the bank negative on a stamped thread
-//! (`CONTEXT_ID != 0`) panics with [`OverdraftPanic`] on the polling thread.
-//! Drop-chain credits during unwind never re-panic — `track` only fires on
-//! debits (`delta < 0`). Unstamped threads are silently skipped.
-//!
-//! Compiled in only when the `memory-accounting` feature is on.

-//! It wraps any [`MemoryPool`] and re-tunes the current thread's bank
-//! account whenever the pool's limit changes (via [`MemoryPool::try_resize`],

-### Allocator-level memory accounting (`--features memory-accounting`)
-
-For tests that need to verify DataFusion's voluntary memory tracking
-matches actual heap usage, the `sqllogictest` runner ships an optional
-`memory-accounting` feature that installs a global allocator wrapper.
-Adding `SET datafusion.runtime.memory_limit = 'N'` at the top of an
-`.slt` file opts that file into allocator-vs-`MemoryPool` reconciliation
-with 10% headroom — any divergence panics the test with an
-`OverdraftPanic` reporting the actual allocator balance. See
-[the sqllogictest README](https://github.com/apache/datafusion/blob/main/datafusion/sqllogictest/README.md#running-tests-allocator-level-memory-accounting)
-for the runner flag and the full mechanism.

Subject: [PATCH 216/878] perf: fast-path inline strings in
 ByteViewGroupValueBuilder::vectorized_append (#21794)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #21568.

## Rationale for this change

`ByteViewGroupValueBuilder::vectorized_append` was doing unnecessary
work for short strings (≤12 bytes): for each row it called
`array.value(row)` to decode the u128 view into a `&[u8]`, then called
`make_view` to re-encode it back into a u128. The input
`GenericByteViewArray` already stores inline values in exactly that u128
format, so the round-trip is redundant.

This mirrors the existing `HAS_BUFFERS` specialisation in
`vectorized_equal_to_inner`, which uses the same
`data_buffers().is_empty()` guard to take a direct-view-compare fast
path for inline strings.

## What changes are included in this PR?

In `vectorized_append_inner`, the `Nulls::None` branch now dispatches on
`arr.data_buffers().is_empty()`:

- **Fast path** (no data buffers → all values ≤12 bytes inline): copies
u128 views directly via `self.views.extend(rows.iter().map(|&row|
arr.views()[row]))`. Arrow's validity invariant guarantees inline views
are zero-padded, so direct copy is semantically identical to `value() →
make_view()`.
- **Slow path** (array has non-inline strings): adds
`self.views.reserve(rows.len())` before the existing loop to avoid
repeated reallocation.

## Are these changes tested?

Covered by the existing 6 unit tests in `bytes_view::tests`, all passing
unchanged. `test_byte_view_vectorized_operation_special_case` exercises
the fast path directly (11-byte strings, no data buffers).

## Are there any user-facing changes?

No. Internal performance improvement only.

## Benchmark

`inline_null_0.0_size_1000/vectorized_append` (8-byte strings, no nulls,
1 000 rows):

Subject: [PATCH 217/878] docs: Update/improve `SELECT` reference  (#22672)

## Which issue does this PR close?

- N/A

## Rationale for this change

Various improvements and cleanups to the `SELECT` reference page in the
documentation. Update the documentation to cover more of the supported
SQL syntax, to include more details when appropriate, and to add more
examples.

## What changes are included in this PR?

* Improve the `SELECT` reference page in the documentation
* Update `pipe_operator.slt` to reflect that the pipe operator syntax is
now supported in the default SQL dialect

## Are these changes tested?

Manually and LLM-checked the examples.

## Are there any user-facing changes?

Documentation improvements, but should be no regressions. No functional
changes in DataFusion.

+Queries in DataFusion scan data from tables, subqueries, table functions, or
+literal values and return zero or more rows. DataFusion supports the following
+general form for `SELECT` queries. Optional clauses can be omitted. The linked
+sections describe each clause in more detail.

+
+Unquoted identifiers are normalized to lower case in SQL queries, but inferred
+schema field names are not changed. If a field name contains capital letters or
+other characters that require quoting, reference it with double quotes. See this
+[example](https://datafusion.apache.org/user-guide/example-usage.html) for
+clarification.
 
 ## WITH clause
 
-A with clause allows to give names for queries and reference them by name.
+```text
+WITH [RECURSIVE] cte_name [(column_name [, ...])] AS (query) [, ...]
+```
+
+A `WITH` clause defines common table expressions (CTEs) that can be referenced
+by name in the rest of the query.
+
+Examples:
 
 ```sql
 WITH x AS (SELECT a, MAX(b) AS b FROM t GROUP BY a)
 SELECT a, b FROM x;
 ```
 
+CTEs can also rename their output columns:
+
+```sql
+WITH x(key, total) AS (
+  SELECT a, SUM(b) FROM t GROUP BY a
+)
+SELECT key, total FROM x;
+```
+
+DataFusion supports `WITH RECURSIVE` for recursive CTEs. Recursive CTE support
+is controlled by the `datafusion.execution.enable_recursive_ctes` configuration
+setting, which is enabled by default.
+
+```sql
+WITH RECURSIVE numbers AS (
+  SELECT 1 AS n
+  UNION ALL
+  SELECT n + 1 FROM numbers WHERE n < 3
+)
+SELECT n FROM numbers;
+```
+
 ## SELECT clause
 
-Example:
+```text
+SELECT [ALL | DISTINCT | DISTINCT ON (expression [, ...])]
+       select_item [, ...]
+       [INTO table_name]
+```
+
+The `SELECT` list can contain column references, arbitrary expressions, scalar
+functions, aggregate functions, window functions, scalar subqueries, and
+wildcards.
+
+Examples:
 
 ```sql
-SELECT a, b, a + b FROM table
+SELECT a, b, a + b AS sum_ab FROM table_name;
 ```
 
-The `DISTINCT` quantifier can be added to make the query return all distinct rows.
-By default `ALL` will be used, which returns all the rows.
+Aliases can be written with or without `AS`:
 
 ```sql
-SELECT DISTINCT person, age FROM employees
+SELECT a AS key, b value FROM table_name;
+```
+
+`SELECT` can be used without a `FROM` clause when the selected expressions do
+not need input rows:
+
+```sql
+SELECT 1 + 2 AS three;
+```
+
+`SELECT *` requires a `FROM` clause.
+
+### DISTINCT
+
+```text
+SELECT DISTINCT select_item [, ...]
+SELECT DISTINCT ON (expression [, ...]) select_item [, ...]
+```
+
+By default, `SELECT` uses `ALL` semantics and returns every row. The `DISTINCT`
+quantifier removes duplicate rows from the query result.
+
+Examples:
+
+```sql
+SELECT DISTINCT person, age FROM employees;
+```
+
+DataFusion also supports PostgreSQL-style `DISTINCT ON`, which keeps one row for
+each distinct value of the listed expressions. Use `ORDER BY` to choose which
+row is kept for each group. When `ORDER BY` is present, the initial `ORDER BY`
+expressions must match the `DISTINCT ON` expressions.
+
+If multiple rows have the same `DISTINCT ON` values and the `ORDER BY` clause
+does not fully order those rows, the row that is kept is not specified. Add
+additional `ORDER BY` expressions to make the choice deterministic.
+
+```sql
+SELECT DISTINCT ON (customer_id) customer_id, order_id, order_date
+FROM orders
+ORDER BY customer_id, order_date DESC;
+```
+
+### Wildcards
+
+```text
+*
+table_alias.*
+* EXCLUDE column_name
+* EXCLUDE (column_name [, ...])
+* EXCEPT column_name
+* EXCEPT (column_name [, ...])
+* REPLACE (expression AS column_name [, ...])
+```
+
+Use `*` to select all columns, or `table_alias.*` to select all columns from a
+specific input.
+
+Examples:
+
+```sql
+SELECT * FROM orders;
+SELECT o.* FROM orders AS o;
+```
+
+Wildcard projections support `EXCLUDE` and `EXCEPT` to omit columns. Both
+accept either a single column name or a parenthesized list of column names.
+
+```sql
+SELECT * EXCLUDE customer_id FROM orders;
+SELECT * EXCLUDE (customer_id, internal_note) FROM orders;
+SELECT * EXCEPT customer_id FROM orders;
+SELECT * EXCEPT (customer_id, internal_note) FROM orders;
+SELECT o.* EXCLUDE (internal_note) FROM orders AS o;
+```
+
+Every name in an `EXCLUDE` or `EXCEPT` list must refer to an existing column.
+The list must not name the same column more than once, and the wildcard must
+not expand to zero columns.
+
+Wildcard projections also support `REPLACE`, which keeps the original column
+name but substitutes a new expression for that column.
+
+```sql
+SELECT * REPLACE (price * 2 AS price) FROM products;
+SELECT p.* REPLACE (price * 2 AS price, product_id + 1000 AS product_id)
+FROM products AS p;
+```
+
+`RENAME` and wildcard aliases such as `* AS alias` are not supported.
+
+### SELECT INTO
+
+```text
+SELECT select_item [, ...] INTO table_name FROM ...
+```
+
+`SELECT ... INTO table_name` creates an in-memory table from the query result.
+It is similar to [`CREATE TABLE ... AS SELECT`](ddl.md#create-table).
+
+```sql
+SELECT customer_id, SUM(amount) AS total
+INTO customer_totals
+FROM orders
+GROUP BY customer_id;
 ```
 
 ## FROM clause
 
-Example:
+```text
+FROM from_item [, ...]
+
+from_item:
+  table_name [[AS] alias [(column_alias [, ...])]]
+| (query) [[AS] alias [(column_alias [, ...])]]
+| VALUES (expression [, ...]) [, ...] [[AS] alias [(column_alias [, ...])]]
+| table_function(argument [, ...]) [[AS] alias [(column_alias [, ...])]]
+| UNNEST(expression) [[AS] alias [(column_alias [, ...])]]
+```
+
+The `FROM` clause specifies the input relations for the query. Supported inputs
+include tables, CTEs, derived tables, `VALUES`, table functions, and `UNNEST`.
+
+Examples:
+
+```sql
+SELECT t.a FROM table_name AS t;
+```
+
+Table aliases can include column aliases:
+
+```sql
+SELECT x, y
+FROM some_table AS t(x, y);
+```
+
+Subqueries can be used in the `FROM` clause:
+
+```sql
+SELECT q.a
+FROM (SELECT a FROM table_name WHERE a > 10) AS q;
+```
+
+`VALUES` can be used as a table expression:
 
 ```sql
-SELECT t.a FROM table AS t
+SELECT *
+FROM VALUES (1, 'a'), (2, 'b') AS t(id, label);
 ```
 
+Table functions such as `range` and `generate_series` can be used in `FROM`:
+
+```sql
+SELECT value FROM range(0, 3);
+```
+
+`UNNEST` expands a list, array, or similar nested value into one row for each
+element. It can be used in the `SELECT` list to expand a value in each input
+row, or as an input relation in `FROM`. When used in `FROM`, it can be given a
+table alias and column alias.
+
+```sql
+SELECT * FROM UNNEST([1, 2, 3]) AS u(value);
+```
+
+To expand a column for each input row, use `UNNEST` in the `SELECT` list:
+
+```sql
+SELECT id, UNNEST(items) FROM orders;
+```
+
+`UNNEST` in the `FROM` clause cannot yet reference columns from preceding `FROM`
+items (implicit lateral references such as `FROM orders AS t, UNNEST(t.items)`
+are not currently supported).
+
 ## WHERE clause
 
-Example:
+```text
+WHERE condition
+```
+
+The `WHERE` clause filters input rows before grouping, aggregation, and window
+processing.
 
 ```sql
-SELECT a FROM table WHERE a > 10
+SELECT a FROM table_name WHERE a > 10;
 ```
 
 ## JOIN clause
 
-DataFusion supports `INNER JOIN`, `LEFT OUTER JOIN`, `RIGHT OUTER JOIN`, `FULL OUTER JOIN`, `NATURAL JOIN`, `CROSS JOIN`, `LEFT SEMI JOIN`, `RIGHT SEMI JOIN`, `LEFT ANTI JOIN`, `RIGHT ANTI JOIN`, `LATERAL JOIN`, and `LEFT JOIN LATERAL`.
+```text
+from_item [join_type] JOIN from_item [join_condition]
+from_item CROSS JOIN from_item
+from_item NATURAL JOIN from_item
+from_item [join_type] JOIN LATERAL (query) AS alias [join_condition]
+from_item, LATERAL (query) AS alias
+

+| FULL [OUTER]
+| LEFT SEMI
+| RIGHT SEMI
+| LEFT ANTI
+| RIGHT ANTI
+
+join_condition:
+  ON condition
+| USING (column_name [, ...])
+```
+
+Joins are written inside the `FROM` clause between input relations.
+
+Join conditions can use `ON` or `USING`.
+
+Examples:
+
+```sql
+SELECT *
+FROM orders AS o
+JOIN customers AS c ON o.customer_id = c.id;

 ## GROUP BY clause
 
-Example:
+```text
+GROUP BY ALL
+GROUP BY grouping_element [, ...]
+
+grouping_element:
+  expression
+  ordinal_position
+  ROLLUP(expression [, ...])
+  CUBE(expression [, ...])
+  GROUPING SETS ((grouping_element [, ...]) [, ...])
+```
+
+The `GROUP BY` clause groups rows before aggregate expressions are evaluated.
+Grouping elements can be expressions, output aliases, or ordinal positions in
+the `SELECT` list.
+
+Examples:
+
+```sql
+SELECT a, b, MAX(c) FROM table_name GROUP BY a, b;
+SELECT a AS key, COUNT(*) FROM table_name GROUP BY key;
+SELECT a, b, COUNT(*) FROM table_name GROUP BY 1, 2;
+```
+
+`GROUP BY ALL` groups by every non-aggregate expression in the `SELECT` list.
 
 ```sql
-SELECT a, b, MAX(c) FROM table GROUP BY a, b
+SELECT a, b, SUM(c) FROM table_name GROUP BY ALL;
 ```
 
-Some aggregation functions accept optional ordering requirement, such as `ARRAY_AGG`. If a requirement is given,
-aggregation is calculated in the order of the requirement.
+Grouping sets allow a single query to compute aggregates for multiple grouping
+levels. `ROLLUP(a, b)` computes aggregate rows grouped by `(a, b)`, then by
+`a`, then over all input rows. `CUBE(a, b)` computes aggregate rows for all
+combinations of `a` and `b`. `GROUPING SETS` lets you list the grouping levels
+explicitly.
+
+```sql
+SELECT a, b, SUM(c) FROM table_name GROUP BY ROLLUP(a, b);
+SELECT a, b, SUM(c) FROM table_name GROUP BY CUBE(a, b);
+SELECT a, b, SUM(c)
+FROM table_name
+GROUP BY GROUPING SETS ((a), (a, b), ());
+```
 
-Example:
+Some aggregate functions accept an optional ordering requirement, such as
+`ARRAY_AGG`. If an ordering requirement is given, aggregation is calculated in
+that order.
 
 ```sql
-SELECT a, b, ARRAY_AGG(c, ORDER BY d) FROM table GROUP BY a, b
+SELECT a, b, ARRAY_AGG(c ORDER BY d) FROM table_name GROUP BY a, b;
 ```
 
 ## HAVING clause
 
-Example:
+```text
+HAVING condition
+```
+
+The `HAVING` clause filters groups after aggregation. It can reference grouping
+expressions, aggregate expressions, and aliases from the `SELECT` list.
+
+```sql
+SELECT a, b, MAX(c) AS max_c
+FROM table_name
+GROUP BY a, b
+HAVING max_c > 10;
+```
+
+## WINDOW clause
+
+```text
+WINDOW window_name AS (window_definition) [, ...]
+```
+
+The `WINDOW` clause defines named window specifications that can be referenced
+from window functions. See [Window Functions](window_functions.md) for the full
+window-function reference.
 
 ```sql
-SELECT a, b, MAX(c) FROM table GROUP BY a, b HAVING MAX(c) > 10
+SELECT
+  depname,
+  empno,
+  salary,
+  AVG(salary) OVER w AS avg_salary
+FROM empsalary
+WINDOW w AS (PARTITION BY depname ORDER BY salary DESC);
 ```
 
 ## QUALIFY clause
 
-Example:
+```text
+QUALIFY condition
+```
+
+The `QUALIFY` clause filters rows after window functions are evaluated. A query
+with `QUALIFY` must contain a window function in either the `SELECT` list or the
+`QUALIFY` expression. `QUALIFY` can reference aliases from the `SELECT` list.
 
 ```sql
-SELECT ROW_NUMBER() OVER (PARTITION BY region) AS rk FROM table QUALIFY rk > 1;
+SELECT ROW_NUMBER() OVER (PARTITION BY region ORDER BY sales DESC) AS rk
+FROM table_name
+QUALIFY rk <= 3;
+```
+
+## Set operations
+
+```text
+query UNION [ALL | DISTINCT] [BY NAME] query
+query INTERSECT [ALL | DISTINCT] query
+query EXCEPT [ALL | DISTINCT] query
 ```
 
-## UNION clause
+Set operations combine the results of two queries into a single result. They
+operate on whole rows rather than on individual columns, and the input queries
+must produce compatible columns. Except for `UNION ... BY NAME` variants,
+inputs must have the same number of output columns.
 
-Example:
+`UNION` returns rows from both inputs and removes duplicates by default.
+`UNION DISTINCT` is equivalent to `UNION`; `UNION ALL` preserves duplicates.
+
+Examples:
 
 ```sql
 SELECT
@@ -419,55 +758,108 @@ SELECT
 FROM table2
 ```
 
+`INTERSECT` returns rows that appear in both inputs. `EXCEPT` returns rows from
+the left input that do not appear in the right input. Both support `ALL` and
+`DISTINCT`.
+
+```sql
+SELECT a FROM table1
+INTERSECT
+SELECT a FROM table2;
+
+SELECT a FROM table1
+EXCEPT ALL
+SELECT a FROM table2;
+```
+
+`UNION BY NAME` matches columns by name instead of by position. `UNION ALL BY NAME` preserves duplicates, and `UNION DISTINCT BY NAME` removes duplicates.
+
+```sql
+SELECT a, b FROM table1
+UNION BY NAME
+SELECT b, a FROM table2;
+```
+
+Set operations can be followed by `ORDER BY`, `LIMIT`, and `OFFSET` clauses,
+which apply to the combined result.
+
 ## ORDER BY clause
 
-Orders the results by the referenced expression. By default it uses ascending order (`ASC`).
-This order can be changed to descending by adding `DESC` after the order-by expressions.
+```text
+ORDER BY order_expression [ASC | DESC] [NULLS FIRST | NULLS LAST] [, ...]
+```
+
+`ORDER BY` sorts query results. Each `order_expression` can be an expression, a
+`SELECT` alias, or an ordinal position. The default direction is ascending
+(`ASC`).
+
+If multiple rows have the same values for every `ORDER BY` expression, their
+relative order is not specified. Add additional `ORDER BY` expressions to break
+ties when the exact row order matters.
 
 Examples:
 
 ```sql
-SELECT age, person FROM table ORDER BY age;
-SELECT age, person FROM table ORDER BY age DESC;
-SELECT age, person FROM table ORDER BY age, person DESC;
+SELECT age, person FROM table_name ORDER BY age;
+SELECT age, person FROM table_name ORDER BY age DESC;
+SELECT age AS years, person FROM table_name ORDER BY years;
+SELECT age, person FROM table_name ORDER BY 1, person DESC;
 ```
 
-## LIMIT clause
+Use `NULLS FIRST` or `NULLS LAST` to control where null values sort:
 
-Limits the number of rows to be a maximum of `count` rows. `count` should be a non-negative integer.
+```sql
+SELECT age, person FROM table_name ORDER BY age DESC NULLS LAST;
+```
 
-Example:
+With the DuckDB dialect, DataFusion supports `ORDER BY ALL`, which orders by
+every column in the `SELECT` list from left to right. All selected items must
+be column references; ordering by computed expressions such as `a + b` is not
+supported:
 
 ```sql
-SELECT age, person FROM table
-LIMIT 10
+SET datafusion.sql_parser.dialect = 'DuckDB';
+SELECT address, zip FROM addresses ORDER BY ALL DESC;
+```
+
+## LIMIT and OFFSET clauses
+
+```text
+[LIMIT count]
+[OFFSET count]
 ```
 
-## EXCLUDE and EXCEPT clause
+`LIMIT` restricts the number of rows returned. `OFFSET` skips rows before
+returning results. The count expressions must be constant expressions that
+evaluate to non-negative integers or `NULL`; column references are not allowed.
+`NULL` has no effect.
 
-Excluded named columns from query results.
+Without an `ORDER BY` clause, `LIMIT` and `OFFSET` operate on an unspecified row
+order, so the returned rows are not guaranteed to be deterministic.
 
-Example selecting all columns except for `age` and `person`:
+Examples:
 
 ```sql
-SELECT * EXCEPT(age, person)
-FROM table;
+SELECT age, person FROM table_name LIMIT 10;
+SELECT age, person FROM table_name OFFSET 20;
+SELECT age, person FROM table_name LIMIT 10 OFFSET 20;
+SELECT age, person FROM table_name OFFSET 20 LIMIT 10;
 ```
 
+DataFusion also accepts MySQL-style `LIMIT offset, count`:
+
 ```sql
-SELECT * EXCLUDE(age, person)
-FROM table;
+SELECT age, person FROM table_name LIMIT 20, 10;
 ```
 
 ## Pipe operators
 
-Some SQL dialects (e.g. BigQuery) support the pipe operator `|>`.
-The SQL dialect can be set like this:
-
-```sql
-set datafusion.sql_parser.dialect = 'BigQuery';
+```text
+query |> pipe_operator [|> pipe_operator ...]
 ```
 
+DataFusion supports BigQuery-style pipe operators (`|>`).
+
 DataFusion currently supports the following pipe operators:

Subject: [PATCH 218/878] feat: implement Spark-compatible weekday function
 (#22740)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22599.

## Rationale for this change

Implements the Spark `weekday` function as part of the datafusion-spark
function library (#15914). Spark's `weekday` returns the day-of-week as
a 0-indexed integer with Monday = 0 .. Sunday = 6, which differs from
the existing `dayofweek` (1-indexed, Sunday = 1). This fills a gap for
Spark-compatibility consumers.

## What changes are included in this PR?

- New `SparkWeekDay` scalar UDF in
`datafusion/spark/src/function/datetime/weekday.rs`, modeled on the
sibling `monthname` function.
- Accepts Date and (implicitly coerced) Timestamp input; returns
`Int32`.
- Uses Arrow's `DatePart::DayOfWeekMonday0` kernel, which is exactly
0=Monday .. 6=Sunday — a direct match for Spark semantics.
- Null input propagates to null output for both scalar and array paths.
- Registered in the datetime function `mod.rs` (UDF macro, doc export,
`functions()` list).

## Are these changes tested?

Yes:
- Rust unit tests: return-field nullability, scalar evaluation (incl.
null), and array evaluation.
- sqllogictest coverage in
`datafusion/sqllogictest/test_files/spark/datetime/weekday.slt`: scalar
dates for all 7 weekdays, array input, TIMESTAMP / TIMESTAMP_NTZ / LTZ
coercion, null handling, and argument-type / zero-argument error cases.
The original PySpark 3.5.5 reference (`weekday('2009-07-30') = 3`) is
preserved and validated.

## Are there any user-facing changes?

Adds the new Spark-compatible scalar function `weekday`. No breaking
changes.

Note: I noticed there is an existing draft PR #22601 for the same
function (last updated 2026-05-28). It appears to be a stale draft, so
I've opened this as a complete, tested implementation — happy to defer
or collaborate if the draft author is still active.

Subject: [PATCH 219/878] fix: Correct output-count stats for partitioned
 partial aggs (#22780)

## Which issue does this PR close?

- Closes #22779

## Rationale for this change

A partial aggregate with no group by expression emits one row per output
partition, even for input partitions that did not receive any rows. The
stats code gets this incorrect, and claims that the partial agg outputs
`Exact(0)` rows in this scenario. This is off by a factor of
`partition_count`, which can lead to suboptimal planning decisions
downstream.

Because `total_byte_size` is scaled from the output row count, this is
also improved: the byte-size estimate now scales with the corrected
output row count rather than the input row count.

## What changes are included in this PR?

* Pass the requested partition into `statistics_inner` and adjust
`statistics_inner` as described above
* Tighten optimizer metadata for grouping sets queries (minor
correctness fix)
* Add/extend existing unit tests

## Are these changes tested?

Yes; new tests added.

## Are there any user-facing changes?

No.

Subject: [PATCH 220/878] fix: map() fails when keys are literals and values
 are column expressions (#22784)

## Which issue does this PR close?

Closes #22781

## Rationale for this change

`map(['a','b'], [col, col * 10])` fails at execution time with "map
requires key and value lists to have the same length" when keys are all
literals and values contain column references.

Root cause: literal keys evaluate to
`ColumnarValue::Scalar(FixedSizeList[N])` (length N) while column values
evaluate to `ColumnarValue::Array` (length batch_size). The length check
compares N != batch_size and errors.

## What changes are included in this PR?

In `make_map_batch`: when one argument is scalar and the other is array,
expand the scalar to match `batch_size` via
`ScalarValue::to_array_of_size(number_rows)` before the length
comparison.

## Are these changes tested?

Yes.
- Unit test: scalar keys + array values in `map.rs`
- SLT test: `SELECT map(['a','b'], [column1, column1 * 10]) FROM (VALUES
(1), (2), (3))`

## Are there any user-facing changes?

No. Previously-failing queries now execute correctly.

in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`array_remove` errored out when given a `NULL` array argument.

`array_replace` handled the `DataType::Null` case, but it always built a
NULL array of length 1, regardless of the actual input length.

`remove` and `replace` share nearly identical implementations, so they
should treat a NULL array argument the same way

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- `array_remove`: handle `DataType::Null` in both
`array_remove_internal` and the scalar fast-path
`array_remove_with_scalar_args`, returning a NULL array of the input
length.
- `array_replace`: fix the existing `DataType::Null` branches to use the
input array length (`array.len()` / `list_array.len()`) instead of a
hard-coded `1`.

## Are these changes tested?

Yes, added slt coverage

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

`array_remove`/`array_remove_n`/`array_remove_all` now return `NULL` for
a `NULL`-typed array argument instead of raising an error. No breaking
API changes.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 223/878] fix: Avoid incorrectly rounding large integers in
 `nanvl` (#22575)

## Which issue does this PR close?

- Closes #22567

## Rationale for this change

`nanvl`'s function signature listed `Float16` first, which meant that
data types not natively supported by the function (e.g., integers) would
be converted to `Float16`. This resulted in unnecessary and incorrect
rounding for large integer inputs (e.g., `nanvl(16777217, 1)` returned
incorrect results).

Instead, we now convert non-floating point inputs to `Float64`. This
might still round for inputs larger than 2^53, but it's the best we can
do without more fundamental changes. Floating point inputs are coerced
to the widest float type they have in common -- e.g., (`Float16`,
`Float32`) -> `Float32`.

## What changes are included in this PR?

* Change function signature to avoid unnecessary rounding
* Update SLT

## Are these changes tested?

Yes; new tests added.

## Are there any user-facing changes?

Yes; `nanvl` now avoids rounding in more cases.

Subject: [PATCH 225/878] fix: preserve async UDF return field metadata
 (#22663)

## Which issue does this PR close?

Closes https://github.com/apache/datafusion/issues/22662.

## Rationale for this change

Async scalar UDFs can compute output field metadata in
`return_field_from_args(...)`, but `AsyncFuncExpr` rebuilt the output
field from only name, data type, and nullability. This dropped metadata
from async UDF result fields.

## What changes are included in this PR?

This PR updates `AsyncFuncExpr::field(...)` to preserve the planned
`return_field` metadata and only rename the field for the async
expression output.

It also adds a regression test that verifies an async UDF result batch
preserves metadata attached by `return_field_from_args(...)`.

## Are these changes tested?

Yes.

Added a regression test in:
-
`datafusion/core/tests/user_defined/user_defined_async_scalar_functions.rs`

The test fails without the fix and passes with the fix.

## Are there any user-facing changes?

Yes.

Async scalar UDF result fields now preserve metadata attached by
`return_field_from_args(...)`.

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Related to #22882.

## Rationale for this change

I opened a new roadmap discussion, [DataFusion 2026 Q3-Q4 Roadmap
Discussion](https://github.com/apache/datafusion/issues/22882), and it
would be nice if public-facing docs pointed readers at it so the
community can find and join the current discussion.

## What changes are included in this PR?

- Add a roadmap pointer to the `README.md` "Contributing to DataFusion"
section linking to the roadmap docs and the current discussion (#22882).
- Update the contributor-guide roadmap page
(`docs/source/contributor-guide/roadmap.md`) to call out #22882 as the
current discussion and list it at the top of the quarterly roadmap
discussions.

## Are these changes tested?

No tests; documentation-only change.

## Are there any user-facing changes?

Documentation only — adds links to the current roadmap discussion.

Subject: [PATCH 227/878] perf: Convert inner joins to semi joins when
 equivalent (#22652)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22594

## Rationale for this change

This PR extends the `EliminateJoin` rewrite pass to replace inner joins
with semi joins in some cases. An inner join `L ⋈ R` can be rewritten to
a left semi join `L ⋉ R` if two conditions hold:

1. None of R's columns are referenced above the join
2. (a) each L row matches at most one R row, OR (b) the consumers of the
join result are insensitive to duplicates

(And symmetrically with right semi joins.)

## What changes are included in this PR?

* Add `for_each_referenced_index` helper that is used by both
`EliminateJoin` and `EliminateProjections`
* Introduce `LiveColumns` type to track the "live" (referenced by
parent) columns of a plan node
* Add inner -> semi join rewrite to `EliminateJoin`
* Add unit and SLT tests for rewrite behavior
* Update SLT test fixtures for plan changes

## Are these changes tested?

Yes; new tests added.

## Are there any user-facing changes?

Some plan changes but no behavioral changes.

-//! [`EliminateJoin`] rewrites `INNER JOIN` with `true`/`null`
-use crate::optimizer::ApplyOrder;
+//! [`EliminateJoin`] rewrites inner joins to simpler forms to make them cheaper
+//! to evaluate. We implement two distinct rewrites:
+//!
+//! * An inner join can be rewritten to an empty relation if the join condition
+//!   is trivially false.
+//!
+//! * An inner join `L ⋈ R` can be rewritten to a left semi join `L ⋉ R`
+//!   (`LeftSemi`), which keeps the rows of L that have a match in R and outputs
+//!   only L's columns. The rewrite to `L ⋉ R` is valid when both of the
+//!   following are true:
+//!
+//!     1. None of R's columns are referenced above the join.
+//!     2. R does not observably multiply L's rows. This holds when either the
+//!        join's ancestors are duplicate-insensitive (e.g., DISTINCT) or we can use
+//!        functional dependencies to prove that each L row matches at most one R
+//!        row (R is provably unique on the join keys).
+//!
+//! # Overview
+//!
+//! `rewrite_subtree` walks the plan top-down, threading two pieces of context
+//! down to each join:
+//!
+//! * `live` — which of the join's output columns are referenced above it. It is
+//!   propagated top-down: each node asks its children only for the columns it
+//!   needs from them, so a projection or aggregate asks for just the columns its
+//!   expressions reference, dropping the rest (the narrowing); a join splits the
+//!   set across its two inputs.
+//! * `duplicate_insensitive` — whether emitting each row once instead of many
+//!   times will not change the output. A duplicate-collapsing node (e.g.,
+//!   DISTINCT, GROUP BY with no aggregate functions, or the existence side of a
+//!   semi/anti/mark join) sets it `true` for its subtree, and it propagates
+//!   downward until a node that makes the row count observable again (a `LIMIT`,
+//!   a top-N sort, ...) clears it. It is therefore fixed by the nearest such
+//!   node, not by the whole ancestor chain: a collapsing node shields its subtree,
+//!   so a duplicate-sensitive node further above does not matter.
+//!
+//! At each join, `rewritten_join_type` combines this context with the side's
+//! functional dependencies to choose `Inner`, `LeftSemi`, or `RightSemi`. Most
+//! node types just forward the context to their single child via
+//! `rewrite_single_input`; nodes that alter column requirements or
+//! duplicate-sensitivity (projection, aggregate, sort, ...) adjust it first.

Subject: [PATCH 228/878] fix: Enable sliding window execution for covar_pop,
 covar_samp, and corr (#22764)

## Which issue does this PR close?

- Closes #22763 .

## Rationale for this change

Bounded sliding window queries using `covar_pop`, `covar_samp`, and
`corr` currently fail with a `retract_batch is not implemented` error,
preventing these aggregates from being used with sliding window frames.

## What changes are included in this PR?

* Included `supports_retract_batch()` for the covariance and correlation
accumulators.
* Added SQL logic tests covering bounded sliding window execution for
covariance and correlation aggregates.

## Are these changes tested?

Yes.

Added SQL logic tests covering:

* Single-row bounded sliding frames
* Multi-row bounded sliding frames

for `covar_pop`, `covar_samp`, and `corr`.

## Are there any user-facing changes?

Yes.

`covar_pop`, `covar_samp`, and `corr` can now be used with bounded
sliding window frames that previously failed. Also, no changes were made
to any public APIs.

Subject: [PATCH 229/878] fix: handle `date_bin` negative subsecond and
 overflow cases (#22610)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22528

## Rationale for this change

`date_bin` had a few edge cases that could return the wrong result,
return an error only on array inputs, or panic/wrap when scaling
timestamp and time values to nanoseconds.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

  - Fix negative sub-second timestamp conversion before the epoch.
- Make scalar and array paths return `NULL` consistently for per-row
binning errors.
- Use checked scaling when converting timestamp and time values to
nanoseconds.
- Return an error for invalid shared origin values that overflow during
scaling.
  - Simplify duplicated stride and scale handling.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?
No public API changes.
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 230/878] feat(spark): add `concat_ws` with array support
 (#20928)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #15914

## Rationale for this change

DataFusion core's `concat_ws` does not support array arguments. Spark's
`concat_ws(sep, ...)` accepts both scalar strings and arrays, expanding
array elements and skipping nulls. This is needed for Spark
compatibility in the `datafusion-spark` crate.


## What changes are included in this PR?

- New `SparkConcatWs` UDF in
`datafusion/spark/src/function/string/concat_ws.rs`
  - Supports `concat_ws(sep, str1, str2, ...)` with scalar strings
- Supports array arguments: `concat_ws(',', array('a', 'b'), 'c')` →
`"a,b,c"`
  - Null scalars and null array elements are skipped (Spark behavior)
  - Null separator returns NULL
  - Zero value arguments (`concat_ws(',')`) returns empty string
  - Supports Utf8, LargeUtf8, Utf8View, List, and LargeList types
- Registered the function in `mod.rs` (`make_udf_function!`,
`export_functions!`, `functions()`)
- Replaced commented-out SLT tests with 14 working test cases covering
basic usage, arrays, mixed arguments, nulls, column expressions, and
edge cases


## Are these changes tested?

Yes.
- 7 unit tests in `concat_ws.rs` (basic, null values skipped, null
separator, list arrays, list with nulls, mixed scalar+list, multiple
rows)
- 14 SLT tests in `spark/string/concat_ws.slt` covering scalars, arrays,
nulls, column expressions, and edge cases


## Are there any user-facing changes?

No. This is a new function in the `datafusion-spark` crate only.

+//! Spark-compatible `concat_ws`: joins strings (and array elements) with a separator.
+//!
+//! Null scalar args and null array elements are skipped; a null separator yields a
+//! null row. Non-string args are coerced to STRING; list args (`List`, `LargeList`,
+//! `ListView`, `LargeListView`, `FixedSizeList`) expand their elements.
+//!
+//! Differences with DataFusion core `concat_ws`:
+//! - Accepts list arguments and expands their elements
+//! - Always returns Utf8 (Spark's `STRING` type)
+//! - Coerces non-string scalars (numbers, booleans, dates, ...) to Utf8

Subject: [PATCH 231/878] fix: preserve Spark next_day whitespace validation
 (#22720)

## Which issue does this PR close?

- Closes #22717.

## Rationale for this change

Spark does not trim `dayOfWeek` before matching it in `next_day`, but
`datafusion-spark` currently does. That makes values like `' MO '`
succeed in DataFusion even though Spark treats them as invalid.

## What changes are included in this PR?

- remove the `.trim()` call from `spark_next_day`
- add a regression test proving whitespace-padded day names are rejected

## Are these changes tested?

- `cargo test -p datafusion-spark
next_day_rejects_whitespace_padded_day_names -- --nocapture`
- `cargo test -p datafusion-spark`
- `cargo fmt --all --check`
- `cargo clippy -p datafusion-spark --all-targets --all-features
--no-deps -- -D warnings`

Note: the broader package clippy invocation still reports an existing
unused import warning in untouched
`datafusion/core/src/execution/session_state.rs` on current main.

## Are there any user-facing changes?

Behavior now matches Spark for whitespace-padded `dayOfWeek` inputs in
`next_day`.

Subject: [PATCH 233/878] Clearly gate sliding SUM(DISTINCT) type support
 (#22866)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22820.

## Rationale for this change

Sliding `SUM(DISTINCT)` only supports `Int64`, but it was routed through
the wider `SUM` type dispatch path. This made unsupported types fail
with a less clear accumulator error.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

This PR adds an explicit `Int64` gate for sliding `SUM(DISTINCT)`.

Unsupported types now return a clear feature error that names the
operation and type. The existing `Int64` path is unchanged.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No public API change

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 234/878] FFI: plumb `placement` for `FFI_ScalarUDF` (#22608)

## Which issue does this PR close?

- Part of #22330.

This is the first of the per-method PRs that issue describes. It plumbs
`placement` only; the remaining defaulted methods follow separately, so
the umbrella issue stays open.

## Rationale for this change

`FFI_ScalarUDF` (`datafusion/ffi/src/udf/mod.rs`) carried no function
pointer for `placement`, and `ForeignScalarUDF` did not override it, so
a producer's override of `ScalarUDFImpl::placement` (default body at
`datafusion/expr/src/udf.rs:1028`) was dropped on the consumer side and
every foreign UDF fell back to `KeepInPlace`. A UDF loaded over FFI
never delivered its leaf-pushdown hint to the optimizer.

## What changes are included in this PR?

- New `FFI_ExpressionPlacement` enum bridge in
`datafusion/ffi/src/placement.rs`, in the shape of `FFI_Volatility`:
`#[repr(u8)]` with `From` impls both ways and a round-trip test over
every variant.
- A `placement` function pointer on `FFI_ScalarUDF`, populated in the
`From<Arc<ScalarUDF>>` constructor, with `placement_fn_wrapper` on the
producer side and a forwarding `ForeignScalarUDF::placement` on the
consumer side. `placement` is infallible, so the pointer returns the
enum directly rather than `FFI_Result`.

Adding a field to the `#[repr(C)]` struct changes its layout, so this is
an API change and should carry the `api change` label (I can't add it
myself). It targets `main` and should not be back-ported to a release
branch.

`display_name` is also on the issue's list, but it has been deprecated
since 50.0.0, so it should be dropped from the gap list rather than
plumbed. I have left it and the remaining methods to follow-up PRs.

## Are these changes tested?

Yes.

- Unit: a round-trip test over all four `ExpressionPlacement` variants,
plus a forced-foreign test (`mock_foreign_marker_id`) using a UDF whose
`placement` override depends on its arguments. The assertions cover
ordered, reordered, and empty argument slices, so argument marshalling
is checked, not just the return value.
- Integration: `tests/ffi_udf.rs` loads the UDF from the real cdylib and
asserts the override survives the boundary, which is the surface a
layout change needs.

Run with `cargo test -p datafusion-ffi` and `cargo test -p
datafusion-ffi --features integration-tests`.

## Are there any user-facing changes?

A `placement` override on a `ScalarUDFImpl` is now preserved across the
FFI boundary instead of being silently replaced by the default. This is
an ABI change to `FFI_ScalarUDF`; consumers must be recompiled against
the new layout.

Subject: [PATCH 235/878] refactor: introduce ProbeEnd state in
 NestedLoopJoinExec (#22865)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22808.

## Rationale for this change

Follow-up to #22791, as suggested in review by @2010YOUY01.

That PR fixed a double-decrement bug where `EmitLeftUnmatched` did two
jobs at once — deciding whether a partition emits unmatched-left rows
(which decrements the shared `probe_threads_counter`) and performing the
emit. Because the state is re-enterable (a ready batch can be flushed
before the state advances to `Done`), the counter could be decremented
twice, driving it to zero before all partitions finished probing and
emitting spurious NULL-padded rows. #22791 patched this with a
`probe_completed_reported` guard flag.

This refactor makes "decrement exactly once per probe stream" a
structural property of the state graph rather than a runtime guard, so
the inner logic is easier to follow and the bug is harder to
reintroduce.

## What changes are included in this PR?

Restructures the state machine from `FetchingRight → EmitLeftUnmatched`
to `FetchingRight → ProbeEnd → EmitLeftUnmatched`:

- Adds a dedicated `ProbeEnd` state, entered exactly once per left chunk
when the right side is exhausted. It owns the single
`report_probe_completed()` call and records whether this stream is the
unmatched-left emitter.
- Replaces the `probe_completed_reported` guard flag with an
`is_unmatched_left_emitter` field that `EmitLeftUnmatched` only reads.
- Removes the per-chunk flag reset in the memory-limited path (the
decision is recomputed in `ProbeEnd` for each chunk) and reverts the
`Arc::clone` workaround #22791 needed in `process_left_unmatched`.
- Updates the state-transition doc graph and arm comments.

No behavior change is expected.

## Are these changes tested?

Yes — covered by existing tests:

- All 42 `nested_loop_join` unit tests and the full
`datafusion-physical-plan` suite pass.
- `joins.slt` sqllogictests pass (including the multi-partition LEFT
JOIN regression test added in #22791).
- 41 `join_fuzz` tests (`cargo test --features extended_tests`)
comparing `NestedLoopJoinExec` against `HashJoinExec` across every join
type, filtered and unfiltered, with a multi-partition probe side — the
exact scenario class of the original bug — pass.
- `cargo fmt` and `cargo clippy --all-targets --all-features -- -D
warnings` are clean.

## Are there any user-facing changes?

No.

Subject: [PATCH 236/878] fix: TRY_CAST returns NULL for timestamp/date
 overflow (#22897)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22896.

## Rationale for this change

`TRY_CAST` should return NULL on cast failure, but overflowing
date/timestamp casts returned errors.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

- Make scalar temporal overflow checks respect CastOptions.safe.
- Skip DataFusion’s array pre-check for safe casts so Arrow can return
NULLs.
- Add regression tests.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes:

```bash
cargo test -p datafusion-common timestamp_overflow_returns
cargo test -p datafusion-expr-common timestamp_array_to_timestamp_overflow
cargo test --test sqllogictests -- datetime/timestamps.slt
```

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

Yes. TRY_CAST for overflowing date/timestamp casts now returns NULL;
regular CAST still errors.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

## Known Limitation

This PR does not add Date array-path coverage yet. For example:

```sql
SELECT TRY_CAST(d AS TIMESTAMP(9))
FROM (VALUES (DATE '3000-01-01')) t(d);
```

This depends on the upstream Arrow fix in apache/arrow-rs#9825. Once
DataFusion updates to an Arrow version containing that fix, we can add
this regression test.

Subject: [PATCH 237/878] fix: count shared buffers once in hash join
 build-side memory accounting (#22862)

## Which issue does this PR close?

- Closes #22861.

## Rationale for this change

When using DataFusion comet I noticed that my hash join operator was
failing with the following error: `Failed to acquire 142606336 bytes
where 17142251456 bytes already reserved and the fair limit is
17179869184 bytes, 4 registered`. Looking into this more, DataFusion
asks to reserve memory for each batch (by default 8192 rows) of the
build side of a hash join - and tries to reserve (without actually
allocating it) num_batches * batch_size. This is problematic when these
are batches are zero-copy slices of a larger batch (e.g.
GroupedHashAggregateStream), since the slice size is evaluated to be the
size of the larger buffer. This is because the reference to the slice
actually keeps the entire buffer from being freed. DataFusion doesn't
overallocate memory (the underlying data is the same), but it does
over-request it (in the centralized accounting system), which can lead
to these "ResourcesExhausted" exceptions.

## What changes are included in this PR?

In this change, we keep track of all of the buffers that we've already
counted via a set of pointers. This way, we don't redundantly request
memory for the whole arrow buffer for each sub-slice of it. We choose
this approach as opposed to just requesting a smaller amount of memory
per batch, because as mentioned before, the pointer to each batch
technically keeps the entire arrow-buffer from being freed.

## Are these changes tested?

The new hash join test fails on main with ResourcesExhausted and passes
with this change.

## Are there any user-facing changes?

No breaking changes. Adds a new public helper
count_record_batch_memory_size to datafusion-common.

Subject: [PATCH 238/878] fix(topk): call attempt_early_completion when filter
 rejects entire batch (#22852)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22849
- A related cross-partition starvation case is tracked separately in
#22874 and addressed by an upcoming follow-up PR — see
[discussion](https://github.com/apache/datafusion/pull/22852#issuecomment-4670382915)
for details

## Rationale for this change

`TopK::insert_batch` short-circuits when the heap's dynamic filter
rejects every row in a batch:

```rust
if !filter.has_true() {
    // nothing to filter, so no need to update
    return Ok(());
}
```

The early-exit check `attempt_early_completion(&batch)` lives later in
the same function, gated on `replacements > 0`. So a batch that the
filter rejects entirely bypasses the check.

The heap's dynamic filter is derived from the heap's worst row (via
`update_filter`). A batch whose rows all come from a strictly worse sort
prefix is exactly the batch the filter rejects entirely — i.e. the very
signal `attempt_early_completion` is designed to detect ("the next batch
is past the heap's boundary, we can stop") is what causes the function
to short-circuit *before* the check runs.

This is a feature-interaction regression between two PRs that were both
correct in isolation. The `attempt_early_completion` mechanism was added
by #15563 (closing #15529). At the time, there was no heap-derived
dynamic filter on TopK, so the only sensible call site was right after a
successful heap insertion. Two months later, #15770 added the
dynamic-filter pushdown for TopK sorts, introducing the
`!filter.has_true()` short-circuit. The two features address different
problems and the new short-circuit didn't connect to the existing
prefix-completion check — which is how this gap opened up.

**Consequence**: on a TopK over an input ordered on the sort prefix,
`finished = true` is never set once the heap stabilizes. Since
`finished` is the signal `SortExec` uses to stop pulling from its input
(via `Poll::Ready(None)` from the TopK stream, which cascades into
dropping the source stream), the source keeps being polled long past the
point where no further row can improve the heap. The LIMIT optimization
effectively degrades to "heap saves memory but reads everything";
sources with cancellable streams (e.g. networked sources) never receive
the cancellation signal.

## What changes are included in this PR?

Single behavioral change in `datafusion/physical-plan/src/topk/mod.rs`:
call `attempt_early_completion(&batch)` immediately before the `return
Ok(())` in the `!filter.has_true()` branch.

Why this scope, not a broader restructuring:

- The existing `attempt_early_completion` call inside `if replacements >
0` is load-bearing for a related case: a batch containing a mix of
"still valuable" rows and "past the boundary" rows. The existing
`test_try_finish_marks_finished_with_prefix` test covers this case —
Batch 2 with `a=[2,3], b=[10,20]` against a heap where `heap.max.a = 2`;
the `(2, 10)` row must be inserted before the check on the `(3, 20)`
last row triggers. Moving the call earlier would skip the insertion of
valuable rows and break that test.
- The bug is specifically that the *short-circuit* path doesn't call the
check. The fix targets exactly that path.
- A related but separate gap is not addressed here: when
`filter.has_true() == true` but `replacements == 0` (the filter accepts
some rows but `find_new_topk_items` ends up inserting none of them), the
existing call inside `if replacements > 0` is also skipped. This
requires a divergence between the heap's filter predicate and the
row-byte comparison used inside `find_new_topk_items`, which shouldn't
normally happen (the filter is derived from the heap's worst row using
the same comparator). A deterministic synthetic repro would likely
require concurrent heap updates from sibling partitions or
boundary-value edge cases (NaN/NULL semantics, type coercion). Happy to
send a follow-up if reviewers want it covered; the workload that
motivated this fix was the filter-rejection case empirically.

## Are these changes tested?

Yes. Added a regression test
`test_try_finish_fires_when_filter_rejects_entire_batch`. The assertion
target is `topk.finished` — the flag that signals "stop pulling from the
source" to upstream consumers (read by `TopKExec::poll_next` to emit
`Poll::Ready(None)`). Asserting that the flag transitions on the
fully-filter-rejected batch is equivalent to asserting that the
source-stopping mechanism activates.

- Builds a TopK over a `(a, b)` sort with prefix `a`, k=3.
- Inserts a batch that fills the heap with rows from `a ∈ {1, 2}`;
`update_filter` tightens the filter to `a < 2 OR (a = 2 AND b < 30)`.
- Inserts a second batch with all rows at `a = 3` — filter rejects every
row.
- Without the fix: `insert_batch` short-circuits, `topk.finished` stays
`false`. Test fails.
- With the fix: `attempt_early_completion` fires (last-row prefix `a =
3` > heap.max prefix `a = 2`), `topk.finished` becomes `true`. Test
passes.

The test also asserts the emitted top-K is unchanged from after batch 1,
confirming no candidate row was incorrectly excluded by the early bail.

All 28 existing `topk::` tests continue to pass (including
`test_try_finish_marks_finished_with_prefix`, which exercises the
mixed-prefix case).

## Are there any user-facing changes?

No public API or output changes. The fix only changes when TopK marks
itself `finished = true` — specifically, it now fires
`attempt_early_completion` for batches that are entirely rejected by the
heap's dynamic filter, where previously it would silently skip the
check. Output of TopK is unchanged; only the early-exit behavior
improves.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
See issue for the background, this PR forward ports below optimization
to the rewritten hash aggregation
- https://github.com/apache/datafusion/pull/11627

After this migration, the performance is back, so this PR also changes
the temporary configuration
`datafusion.execution.enable_migration_aggregate` default to `true` --
the new path will be used by default.

is sometimes worth providing a summary of the individual changes in this
PR.
-->

This PR is easier to read commit-by-commit.

1. Cleanup the state machine in hash aggregation with typestate pattern
2. Move common util for partial hash aggregation skip from
`aggregates/row_hash.rs` -> `aggregates/utils.rs`
3. Implement the same optimization to the migrated aggregation
4. Set configuration `enable_migration_aggregate` default to true

 datafusion.execution.coalesce_batches true When set to true, record batches will be examined between each operator and small batches will be coalesced into larger batches. This is helpful when there are highly selective filters or joins that could produce tiny output batches. The target batch size is determined by the configuration setting
 datafusion.execution.collect_statistics true Should DataFusion collect statistics when first creating a table. Has no effect after the table is created. Applies to the default `ListingTableProvider` in DataFusion. Defaults to true.
 datafusion.execution.enable_ansi_mode false Whether to enable ANSI SQL mode. The flag is experimental and relevant only for DataFusion Spark built-in functions When `enable_ansi_mode` is set to `true`, the query engine follows ANSI SQL semantics for expressions, casting, and error handling. This means: - **Strict type coercion rules:** implicit casts between incompatible types are disallowed. - **Standard SQL arithmetic behavior:** operations such as division by zero,   numeric overflow, or invalid casts raise runtime errors rather than returning   `NULL` or adjusted values. - **Consistent ANSI behavior** for string concatenation, comparisons, and `NULL` handling. When `enable_ansi_mode` is `false` (the default), the engine uses a more permissive, non-ANSI mode designed for user convenience and backward compatibility. In this mode: - Implicit casts between types are allowed (e.g., string to integer when possible). - Arithmetic operations are more lenient — for example, `abs()` on the minimum   representable integer value returns the input value instead of raising overflow. - Division by zero or invalid casts may return `NULL` instead of failing. # Default `false` — ANSI SQL mode is disabled by default.
-datafusion.execution.enable_migration_aggregate false Temporary switch for aggregate stream implementations that are being migrated from `GroupedHashAggregateStream`. When set to true, DataFusion tries the migrated implementations when their preconditions are satisfied. When set to false, grouped aggregation falls back to `GroupedHashAggregateStream`. This option will be removed after the migration is finished. See <https://github.com/apache/datafusion/issues/22710> for details.

This option will be removed after the migration is finished. See <https://github.com/apache/datafusion/issues/22710> for details.
 datafusion.execution.enable_recursive_ctes true Should DataFusion support recursive CTEs
 datafusion.execution.enforce_batch_size_in_joins false Should DataFusion enforce batch size in joins or not. By default, DataFusion will not enforce batch size in joins. Enforcing batch size in joins can reduce memory usage when joining large tables with a highly-selective join filter, but is also slightly slower.
 datafusion.execution.hash_join_buffering_capacity 0 How many bytes to buffer in the probe side of hash joins while the build side is concurrently being built. Without this, hash joins will wait until the full materialization of the build side before polling the probe side. This is useful in scenarios where the query is not completely CPU bounded, allowing to do some early work concurrently and reducing the latency of the query. Note that when hash join buffering is enabled, the probe side will start eagerly polling data, not giving time for the producer side of dynamic filters to produce any meaningful predicate. Queries with dynamic filters might see performance degradation. Disabled by default, set to a number greater than 0 for enabling it.

 | datafusion.execution.spill_compression                                  | uncompressed              | Sets the compression codec used when spilling data to disk. Since datafusion writes spill files using the Arrow IPC Stream format, only codecs supported by the Arrow IPC Stream Writer are allowed. Valid values are: uncompressed, lz4_frame, zstd. Note: lz4_frame offers faster (de)compression, but typically results in larger spill files. In contrast, zstd achieves higher compression ratios at the cost of slower (de)compression speed.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

Subject: [PATCH 241/878] refactor(hash-aggr): Migrate existing tests on
 `GroupsHashAggregateStream` (#22953)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

Part of https://github.com/apache/datafusion/issues/22710

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
The goal is after we have fully migrated from the old `row_hash.rs`, the
existing UTs should be kept. Specifically, all tests that include
`GroupedHashAggregateStream`

There are 3 previous PRs for the migration have been merged, some
existing UTs are applicable to them, this PR migrated those tests to the
new implementation.

The test migration includes:
1. copy and paste test case
2. Change `GroupedHashAggregateStream` to `PartialHashAggregateStream`
(or other stream in new impl)
3. Left a comment on the migrated test case, so in the final delete move
it's more clear which tests have already been moved.

This PR moved 2 applicable UTs, and updated the comments for all the
tests moved previously.

(Just some random thoughts, in general I don't think it's a good idea to
write tests against low-level utilities like
`GroupedHashAggregateStream`, all tests should better be at SQL level,
or at least at `ExecutionPlan` level, so their test goal are more likely
to survive refactors)

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
5. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 242/878] refactor: remove `opt_filter` in
 `GroupsAccumulator::merge_batch` (#22816)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22775.

## Rationale for this change

the `opt_filter` on `GroupsAccumulator::merge_batch` is a dead
parameter. Aggregate `FILTER` clauses only apply to raw input rows in
the update phase (`update_batch`). `merge_batch` combines already
pre-aggregated states, so there is no per-row filtering to do —
`opt_filter` is meaningless there.

The code confirms this:
- The only production caller (`row_hash.rs`) always passed `None`.
- Existing implementations already ignored it — e.g. `correlation.rs`
asserted `opt_filter.is_none()`, and Spark `avg` used `_opt_filter`.

## What changes are included in this PR?

- Removed `opt_filter` from `merge_batch` in the trait and all
implementations (built-in aggregates, `physical-expr-common`,
`functions-aggregate-common`, Spark, and FFI).
- Updated the trait docs to say `merge_batch` has no `opt_filter`
because filtering happens in the update phase.
- Changed the group zero-init path in `row_hash.rs` to always use
`update_batch` with an all-false filter instead of branching to
`merge_batch`. `update_batch` always takes raw argument types (what
`aggregate_arguments` provides), and since every row is filtered out the
data never matters — this is simpler and more correct.
- Updated all call sites and tests.

## Are these changes tested?

Yes. Existing aggregate tests cover this and were updated to the new
signature. The `first_last` tests were adjusted (with comments) to match
the merge behavior without a filter, and the FFI and Spark tests were
updated too.

## Are there any user-facing changes?

Yes — this is a breaking change to the public `GroupsAccumulator` trait:
`opt_filter` is removed from `merge_batch`. Custom implementations and
direct callers must update their signatures.

+### `GroupsAccumulator::merge_batch` no longer takes `opt_filter`
+
+The `opt_filter` argument has been removed from
+`datafusion_expr_common::groups_accumulator::GroupsAccumulator::merge_batch`:
+
+```diff
+  fn merge_batch(
+      &mut self,
+      values: &[ArrayRef],
+      group_indices: &[usize],
+-     opt_filter: Option<&BooleanArray>,
+      total_num_groups: usize,
+  ) -> Result<()>;
+```
+
+Aggregate `FILTER` clauses only apply to raw input rows during the partial
+(update) phase, so by the time intermediate states are merged there is nothing
+left to filter per row. In practice `opt_filter` was always `None` here, so
+removing it makes the API self-explanatory and impossible to misuse.
+
+**Who is affected:**
+
+- Anyone with a custom `GroupsAccumulator` implementation.
+- Anyone calling `merge_batch` directly.
+
+**Migration guide:**
+
+Drop the `opt_filter` argument from your `merge_batch` signature and from any
+call sites:
+
+```diff
+  fn merge_batch(
+      &mut self,
+      values: &[ArrayRef],
+      group_indices: &[usize],
+-     opt_filter: Option<&BooleanArray>,
+      total_num_groups: usize,
+  ) -> Result<()> {
+      // ...
+  }
+```
+
+```diff
+- acc.merge_batch(values, group_indices, None, total_num_groups)?;
++ acc.merge_batch(values, group_indices, total_num_groups)?;
+```
+
+If your implementation previously inspected `opt_filter` (for example asserting
+it was `None`), that code can simply be deleted.
+
+See [issue #22775](https://github.com/apache/datafusion/issues/22775) for details.

Subject: [PATCH 243/878] Include `null_aware` status in the relevant Join node
 display implementations (#22913)

## Which issue does this PR close?

- Closes #22912.

## Rationale for this change

This change makes testing null_aware behavior easier, and also makes the
performance of various joins clearer - null_aware joins do extra work.

This was originally part #21585, but it seems like there is a bunch of
activity around null-aware joins, so I figured its worth splitting out.

## What changes are included in this PR?

Add a `null_aware` indication to relevant Display implementations when
appropriate.

## Are these changes tested?

SLT tests

## Are there any user-facing changes?

Display only

<h2>2.13.0</h2>
<h1>PyJWT 2.13.0 — Security Release</h1>
<p>This release bundles five security fixes plus three additional
hardening / spec-compliance changes. We recommend all users upgrade.</p>
<h2>Security</h2>
<ul>
<li>
<p><strong><a
href="https://github.com/jpadilla/pyjwt/security/advisories/GHSA-xgmm-8j9v-c9wx"><code>GHSA-xgmm-8j9v-c9wx</code></a>
— JWK JSON accepted as HMAC secret (algorithm confusion).</strong>
<code>HMACAlgorithm.prepare_key</code> previously rejected PEM- and
SSH-formatted asymmetric keys but did not catch a JWK passed as a raw
JSON string. In a verifier configured with both symmetric and asymmetric
algorithms in <code>algorithms=[…]</code> and a raw-JSON JWK as the key,
an attacker could forge HS256 tokens using the JWK text as the HMAC
secret. The guard has been extended to reject any JWK-shaped JSON.

— Algorithm allow-list bypass with <code>PyJWK</code> /
<code>PyJWKClient</code>.</strong> When verifying with a
<code>PyJWK</code>, the caller's <code>algorithms=[…]</code> allow-list
was checked against the token header <code>alg</code> as a string only;
actual verification used the algorithm bound to the <code>PyJWK</code>.
An attacker who controlled a registered JWKS key could sign with one
algorithm and advertise another on the header. PyJWT now requires the
token header <code>alg</code> to match the <code>PyJWK</code>'s
algorithm before verification. <em>Reported by <a

— DoS via base64 decode of unused payload segment when
<code>b64=false</code>.</strong> For detached-payload JWS
(<code>b64=false</code>), the compact-form payload segment was
base64-decoded before being discarded in favor of the caller-supplied
<code>detached_payload</code>. An attacker could inflate the unused
segment to force CPU + memory cost without holding a valid signature.
The segment is now required to be empty per RFC 7515 Appendix F, and is
no longer decoded. <em>Reported by <a

— <code>PyJWKClient</code> accepts non-HTTP(S) URIs.</strong>
<code>PyJWKClient.fetch_data</code> passed its URI to
<code>urllib.request.urlopen</code>, which by default also handles
<code>file://</code>, <code>ftp://</code>, and <code>data:</code>
schemes. An application that fed an attacker-influenced URI into
<code>PyJWKClient</code> could be coerced into reading local files or
reaching other unintended schemes. <code>PyJWKClient</code> now rejects
any URI whose scheme isn't <code>http</code> or <code>https</code>.

— <code>PyJWKClient</code> cache wiped on fetch error.</strong> A
<code>finally</code>-block <code>put(jwk_set=None)</code> cleared the
JWK Set cache whenever a fetch raised, turning a transient JWKS-endpoint
outage into application-wide auth failure. The cache write was moved
into the success path; transient errors no longer evict valid cached
keys. <em>Reported by <a

<li>Forward per-call <code>options</code> (including
<code>enforce_minimum_key_length</code>) from <code>PyJWT.decode</code>
through to <code>PyJWS._verify_signature</code>. The option was
previously silently dropped between the two layers, so it only took
effect when set on the <code>PyJWT</code> instance. <em>Thanks to <a

<li><strong>RFC 7797 §3 compliance for <code>b64=false</code>:</strong>

</ul>
<h2>Upgrade notes</h2>
<p>Most fixes are invisible to correctly-configured callers. A few
behavioral changes you may encounter:</p>
<ul>
<li><strong>Empty HMAC keys now raise.</strong> If your app passed
<code>&quot;&quot;</code> or <code>b&quot;&quot;</code> as a secret
(often via a missing env var, e.g.
<code>os.getenv(&quot;JWT_SECRET&quot;, &quot;&quot;)</code>),
<code>encode</code>/<code>decode</code> will now raise
<code>InvalidKeyError</code>. This is the intended behavior — fix the
configuration.</li>
<li><strong><code>PyJWK</code> decoding now requires the token's
<code>alg</code> to match the JWK's algorithm.</strong> Previously a
mismatch was silently honored if the header <code>alg</code> appeared in
the allow-list. Tokens that relied on this mismatch will now fail with
<code>InvalidAlgorithmError</code>.</li>
<li><strong><code>PyJWKClient</code> now rejects non-HTTP(S) URIs at
construction time.</strong> Tests or dev environments that fetched JWKS
from <code>file://</code> URIs need to switch to a local HTTP server or
load the JWKS by other means (e.g. construct
<code>PyJWKSet.from_dict(...)</code> directly).</li>
<li><strong><code>b64=false</code> tokens are now strictly RFC 7515 /
7797 compliant.</strong> Tokens with a non-empty compact-form payload
segment, or that omit <code>&quot;b64&quot;</code> from
<code>crit</code>, will be rejected. PyJWT-produced tokens always
satisfy both invariants, so round-trips through PyJWT are
unaffected.</li>
<li><strong><code>enforce_minimum_key_length</code> set per-call now
takes effect.</strong> Callers who passed
<code>options={&quot;enforce_minimum_key_length&quot;: True}</code> to
<code>jwt.decode()</code> previously got no enforcement; they will now
get <code>InvalidKeyError</code> on undersized keys, as documented.</li>

<p>Security</p>
<pre><code>
- Reject JWK JSON documents passed as raw HMAC secrets in
  ``HMACAlgorithm.prepare_key`` to close an algorithm-confusion gap that
  the existing PEM/SSH guard did not cover. Reported by @aradona91 in
`GHSA-xgmm-8j9v-c9wx
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-xgmm-8j9v-c9wx&gt;`__.
- Bind the JWT header ``alg`` to ``PyJWK.algorithm_name`` during
  verification so the caller's ``algorithms=[...]`` allow-list cannot be
bypassed when decoding with a ``PyJWK`` / ``PyJWKClient`` key. Reported
by @sushi-gif in `GHSA-jq35-7prp-9v3f
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-jq35-7prp-9v3f&gt;`__.
- Reject non-``http(s)`` URI schemes in ``PyJWKClient`` so attacker-
influenced URIs cannot read local files or reach unintended schemes via
urllib's default ``file://`` / ``ftp://`` / ``data:`` handlers. Reported
by @KEIJOT in `GHSA-993g-76c3-p5m4
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-993g-76c3-p5m4&gt;`__.
- Preserve the cached JWK Set on fetch errors in
``PyJWKClient.fetch_data``.
  The previous ``finally``-block ``put(None)`` pattern cleared the cache
on any transient outage, turning one bad JWKS request into application-
wide auth failure. Reported by @eddieran in `GHSA-fhv5-28vv-h8m8
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-fhv5-28vv-h8m8&gt;`__.
- Skip the unconditional base64 decode of the compact-form payload
segment
  when ``b64=false`` is set in the protected header, and require that
  segment to be empty (RFC 7515 Appendix F detached form). Closes an
  unauthenticated DoS amplifier. Reported by @thesmartshadow in
`GHSA-w7vc-732c-9m39
&lt;https://github.com/jpadilla/pyjwt/security/advisories/GHSA-w7vc-732c-9m39&gt;`__.
<p>Fixed</p>
<pre><code>
- Reject empty HMAC keys outright in ``HMACAlgorithm.prepare_key`` with
  ``InvalidKeyError`` instead of accepting them with only a warning.
  Thanks to @SnailSploit and @spartan8806 for independently flagging the
  footgun.
- Forward per-call ``options`` (including
``enforce_minimum_key_length``)
  from ``PyJWT.decode`` through to ``PyJWS._verify_signature`` so the
option actually takes effect when set at the call site rather than only
  on the ``PyJWT`` instance. Thanks to @WLUB for the report.
- RFC 7797 §3 compliance for ``b64=false``: the encoder now auto-adds
``&amp;quot;b64&amp;quot;`` to the ``crit`` header parameter, and the
decoder rejects
tokens that set ``b64=false`` without listing it in ``crit``. Thanks to
  @MachineLearning-Nerd for the report.

Subject: [PATCH 245/878] ci: Setup valid `Cargo.lock` for `depcheck` to
 unblock CI (#22933)

## Which issue does this PR close?

- Closes #22932

## Rationale for this change

`depcheck` stopped working because an underlying dependency released a
non-semver compatible change (`time 0.3.48`, not going to link to the
issue there because people are already spamming it). Because there was
no lockfile, every run pulled the most recent versions for all
dependencies, which don't currently compile.

## What changes are included in this PR?

1. Add lockfile to `depcheck`
2. Make sure to run `depcheck` with `--lock` in CI

## Are these changes tested?

Tested locally

## Are there any user-facing changes?

None

Subject: [PATCH 246/878] feat: decimal support for gcd and lcm (#22655)

## Which issue does this PR close?

- Closes #19057.

## Rationale for this change

A binary gcd and lcm UDF in the datafusion-functions crate supports only
Int64, but not Decimals. Adding missing support for decimals.

## What changes are included in this PR?

1. Updated gcd and lcm functions to add decimal support. The integer
path is more performant and stays intact. For decimals, the Euclidean
algorithm is used for GCD
2. Added coercion rules: casting to decimals if any argument is decimal;
otherwise, stay with ints as before
3. Common functionality extracted to `common.rs` to avoid inter-UDF
dependency
4. In order to use `calculate_binary_math` for Decimals, updated it to
accept a target type instead of raw `Decimal128Type::DATA_TYPE` - it
causes scaling issues for these UDFs, see #19621


A bit more on (4). The driving force is this failing example:
```sql
query R
select gcd(2::decimal(38, 0), 3::decimal(38, 0));
----
1
```
Previously in #19874, I suggested a more complicated solution to extend
`calculate_binary_math`. However, it only affected gcd/lcm and could be
considered overkill. This PR extends these functions with an extra
parameter `cast_target` for `calculate_binary_decimal_math` to perform a
proper cast to the actual type used, rather than to the default
`Decimal128Type::DATA_TYPE` - it is much lighter.

## Are these changes tested?

- Added unit test for UDFs with decimals for array and scalar paths
- Added unit tests for the gcd/lcm math itself
- Added new SLT tests for decimals

## Are there any user-facing changes?

No

Subject: [PATCH 247/878] Add `file_row_index` UDF to query file-level row
 indexes from Parquet files (#22604)

## Which issue does this PR close?

- Part of #20135

## Rationale for this change

This PR includes the "front end" side of @mbutrovich's #22026, bridging
the last mile to allow users to query file row indexes.

## What changes are included in this PR?

1. A new Scalar UDF `file_row_index`, following #20071's example. The
function returns 0-based row indexes for Parquet scans.
2. Expands the row-filter PushdownChecker to also check if the predicate
contains the new function, denying it from being pushed down if it does.
3. I've added a couple of utilities to find or rewrite ScalarUDF
instances in physical expressions trees, I've seen @alamb point this
mistake out in multiple PRs (including
[here](https://github.com/apache/datafusion/pull/20071#discussion_r3250815183)).
They can also be used in #20071. They are currently in
`schema_rewriter.rs` which was the best place I could think of, but
maybe they should be move elsewhere.
4. A dedicated rewrite function for `file_row_index`, which turns it
into a `Cast(Column(...))`, which is required to return Int64 values.
5. In `ParquetSource::try_pushdown_projection`, we look for
`FileRowIndexFunc`, and if it exists we rewrite it and the source's
table schema.

## Are these changes tested?

In addition to individual unit tests, I've added a new SLT file
(`file_row_index.slt`) that tests for the following cases:
1. Querying `file_row_index` from a table backed by multiple files
2. Filtering on `file_row_index` when its part of the projection
3. Filtering on `file_row_index` when its **not** of the projection,
when filter pushdown is either enabled or disabled (this part didn't
work in a previous iteration, but figured it out today).

## Are there any user-facing changes?

1. New scalar function type - `FileRowIndexFunc`/`file_row_index`,
5. Rewrite logic in `physical-expr-adapter` -
`rewrite_file_row_index_expr` specifically for the new UDF,
`rewrite_file_row_index_projection` to rewrite the `ProjectionExprs` and
two utility functions that should make it clearer how to manipulate and
find ScalarUDFs in physical expressions - `expr_references_scalar_udf`
and `rewrite_scalar_udf`.

+### `file_row_index`
+
+Returns the zero-based row offset within the source file
+that produced the current row.
+
+The value is scoped to one file, so rows from different files in the same scan
+can have the same row index. This function is intended to be rewritten at
+file-scan time. If the input file is not known (for example, if this function
+is evaluated outside a file scan, or was not pushed down into one), direct
+evaluation returns an error.
+
+```sql
+file_row_index()
+```
+
+#### Example
+
+```sql
+SELECT file_row_index() FROM t;
+```
+
 ### `get_field`
 
 Returns a field within a map or a struct with the given key.

Subject: [PATCH 249/878] chore(deps): bump cryptography from 46.0.7 to 48.0.1
 (#22968)

Bumps [cryptography](https://github.com/pyca/cryptography) from 46.0.7
to 48.0.1.
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/pyca/cryptography/blob/main/CHANGELOG.rst">cryptography's
changelog</a>.</em></p>
<blockquote>
<p>48.0.1 - 2026-06-09</p>
<pre><code>
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL
4.0.1.
<p>.. _v48-0-0:</p>
<p>48.0.0 - 2026-05-04<br />
</code></pre></p>
<ul>
<li>
<p><strong>BACKWARDS INCOMPATIBLE:</strong> Support for Python 3.8 has
been removed.
<code>cryptography</code> now requires Python 3.9 or later.</p>
</li>
<li>
<p><strong>BACKWARDS INCOMPATIBLE:</strong> Loading an X.509 CRL whose
inner
<code>TBSCertList.signature</code> algorithm does not match the outer
<code>signatureAlgorithm</code> now raises <code>ValueError</code>.
Previously, such CRLs
were parsed successfully and only rejected during signature
validation.</p>
</li>
<li>
<p>Added support for
:doc:<code>/hazmat/primitives/asymmetric/mlkem</code> and
:doc:<code>/hazmat/primitives/asymmetric/mldsa</code> when using OpenSSL
3.5.0 or
later, in addition to the existing AWS-LC and BoringSSL support. This
means
post-quantum algorithms are now available to users of our wheels.</p>
<ul>
<li><strong>Note:</strong> Going forward, we do not guarantee that all
functionality
in <code>cryptography</code> will be available when building against
OpenSSL. See :doc:<code>/statements/state-of-openssl</code> for more
information.</li>
</ul>
</li>
</ul>
<p>.. _v47-0-0:</p>
<p>47.0.0 - 2026-04-24</p>
<pre><code>
* Support for Python 3.8 is deprecated and will be removed in the next
  ``cryptography`` release.
* **BACKWARDS INCOMPATIBLE:** Support for binary elliptic curves
  (``SECT*`` classes) has been removed. These curves are rarely used and
  have additional security considerations that make them undesirable.
* **BACKWARDS INCOMPATIBLE:** Support for OpenSSL 1.1.x has been
removed.
OpenSSL 3.0.0 or later is now required. LibreSSL, BoringSSL, and AWS-LC
  continue to be supported.
* **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL &lt; 4.1.
* **BACKWARDS INCOMPATIBLE:** Loading keys with unsupported algorithms
or
  keys with unsupported explicit curve encodings now raises
  :class:`~cryptography.exceptions.UnsupportedAlgorithm` instead of
  ``ValueError``. This change affects

:func:`~cryptography.hazmat.primitives.serialization.load_pem_private_key`,

:func:`~cryptography.hazmat.primitives.serialization.load_der_private_key`,

:func:`~cryptography.hazmat.primitives.serialization.load_pem_public_key`,

:func:`~cryptography.hazmat.primitives.serialization.load_der_public_key`,
  and :meth:`~cryptography.x509.Certificate.public_key` when called on
  certificates with unsupported public key algorithms.
&lt;/tr&gt;&lt;/table&gt;
</code></pre>

Subject: [PATCH 251/878] Remove orphaned `snowflake_flatten_validation.sql`
 script (#22938)

## Which issue does this PR close?

- Closes #.

## Rationale for this change

This file seems to be a leftover of #21593. I see what its trying to do,
but most developers don't have access to a Snowflake instance, and the
transformations are already all coded in tests.

I looked into turning it into some sort of SLT tests, but I couldn't
find a Snowflake-provided mock server.

## What changes are included in this PR?

- Remove `snowflake_flatten_validation.sql`

## Are these changes tested?

Existing tests. I ran all the tests in `datafusion-sql` to make sure
there's no hidden dependency I missed.

## Are there any user-facing changes?

None

Subject: [PATCH 252/878] fix: Disable join dynamic filters for null-equal
 joins (#22965)

## Which issue does this PR close?

- Closes ##22964

## Rationale for this change

We presently allow dynamic filter pushdown to be applied to null-equal
hash joins. This might result in pushing a predicate down into the
probe-side plan, where the predicate will not be evaluated with the
null-equal semantics that are required.

Longer-term, we might consider supporting this case with the correct
semantics (e.g., generate a predicate with `OR IS NULL ...`), but for
now disabling pushdown for null-equal joins seems much more practical.

## What changes are included in this PR?

* Disable hash join dynamic filter pushdown for null-equal joins
* Add SLT test with end-to-end repro
* Add unit test

## Are these changes tested?

Yes.

## Are there any user-facing changes?

No.

Subject: [PATCH 258/878] refactor: Update SortMergeJoin to use async spill
 abstractions (#22230)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

~~## Note: This PR depends on #21882 (pluggable SpillFile trait) and
cannot be merged before it. Opening in parallel per @alamb's suggestion
for easier review. The required SpillFile trait used here is defined in
that base PR.To review locally, apply #21882 first and then stack this
branch on top.~~
**Update:** This PR has been rebased to use the existing
`RefCountedTempFile` and is now completely standalone. It can be
reviewed and merged independently

## Which issue does this PR close?

- Contributes to #21215 (and is required by #21882)

## Rationale for this change

`materializing_stream.rs` and `bitwise_stream.rs` were reading spilled
batches via `open_sync_reader` / direct `File::open` calls ~~, bypassing
the `SpillFile` abstraction introduced in #21882~~. This PR migrates
both to use `SpillManager::read_spill_as_stream`. This safely converts
the SMJ to an async I/O path, preparing the ground for custom backends
(Postgres BufFile, object storage) to handle spill reads without
requiring an OS file path.

## What changes are included in this PR?

- `materializing_stream.rs`: Eagerly restores spilled `BufferedBatches`
via async streams before freezing, avoiding new state machine variants.
- `bitwise_stream.rs`: Replaces sync reads with an async
`poll_next_unpin` loop, caching the stream to survive `Poll::Pending`.
~~- `spill_file.rs`: Removes `open_sync_reader` from the `SpillFile`
trait (no longer needed).~~

## Are these changes tested?

Covered by existing SMJ tests. No new tests added, the behavioral change
is internal (sync → async IO path).

## Are there any user-facing changes?

No.
~~Removes `open_sync_reader` from the SpillFile trait, this is a
breaking API change for anyone implementing the trait, but the trait was
introduced in #21882 which has not merged yet so there are no external
implementors.~~

Subject: [PATCH 260/878] Fix leaf expression reconciliation (#22971)

## Which issue does this PR close?

- Closes https://github.com/apache/datafusion/issues/22955

## Rationale for this change

This fixes a bug with the extract leaf expressions

## What changes are included in this PR?

This is a one liner that sanity checks the schema is the same length
when we are doing expression pushdown

## Are these changes tested?

Yes, a couple of tests have been added.

## Are there any user-facing changes?

Nope!

Subject: [PATCH 261/878] Add MERGE INTO types to datafusion-expr (#20763)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- part of #20746

[EPIC] Complete DML Support (MERGE, INSERT OVERWRITE, TRUNCATE) #19617
As well as task 1 of #20746

## Rationale for this change

Lay the foundation for MERGE INTO support in DataFusion by adding the
logical plan types and their proto serialization. Keeping types separate
from execution lets reviewers reason about the data model independently
of the planner and physical dispatch.

## What changes are included in this PR?

**`datafusion/expr` — new types in `dml.rs`**
- `MergeIntoOp` — carries the `ON` join condition and ordered list of
`WHEN` clauses
- `MergeIntoClause` — a single `WHEN` clause: kind + optional predicate
+ action
- `MergeIntoClauseKind` — `Matched` / `NotMatched` /
`NotMatchedByTarget` / `NotMatchedBySource`; includes
`is_not_matched_by_target()` and `canonical()` helpers because
`NotMatched` and `NotMatchedByTarget` are semantically identical and
must be treated identically downstream
- `MergeIntoAction` — `Update(Vec<(col, expr)>)` / `Insert { columns,
values }` / `Delete`
- `WriteOp::MergeInto(MergeIntoOp)` variant added to the existing
`WriteOp` enum; `WriteOp` is now `#[non_exhaustive]` so future variant
additions are not a SemVer break

**`datafusion/proto-models` — proto schema**
- Extended `DmlNode` with a `MERGE_INTO` type tag and a boxed
`MergeIntoOpNode` payload field
- Added `MergeIntoOpNode`, `MergeIntoClauseNode`, `MergeIntoActionNode`
messages

**`datafusion/proto` — serialization**
- `from_proto`: `parse_write_op(&DmlNode, ...)` reads the payload when
the type tag is `MergeInto`; defensive helpers
`parse_merge_into_op/clause/action` with explicit errors for missing
fields
- `to_proto`: `serialize_merge_into_op/clause/action` helpers; encode
path uses an explicit `match` over all `WriteOp` variants producing
`(dml_type, merge_into)` pair — no silent payload loss
- Cross-crate conversions use `FromProto` (the crate-local trait) rather
than `From` to satisfy the Rust orphan rule after the upstream
`datafusion-proto-models` refactor

**Proto codegen** — after editing `.proto` files, regenerate with:
```bash
PROTOC=/tmp/protoc cargo run --manifest-path datafusion/proto-models/gen/Cargo.toml
```
(Install `protoc` from
https://github.com/protocolbuffers/protobuf/releases if not present; set
`PROTOC` to its path.)

## Are these changes tested?

- `datafusion-expr` unit tests: `WriteOp::MergeInto` display,
`is_not_matched_by_target`, `canonical`
- `datafusion-proto` round-trip test: exercises all four
`MergeIntoClauseKind` variants and all three `MergeIntoAction` variants
through encode → decode
- `datafusion-proto` error-path tests: missing `merge_into` payload,
missing `on` expression, unknown clause kind tag, missing clause action,
missing action oneof

## Are there any user-facing changes?

`WriteOp` gains a `MergeInto` variant and is now `#[non_exhaustive]`.
Existing downstream `match` arms need a wildcard arm added (this is
intentional and expected for a new DML operation).

## Follow-up

A stacking PR that adds the SQL planner, physical planner dispatch, and
`TableProvider::merge_into` hook is available at
https://github.com/wirybeaver/datafusion/pull/2. If reviewers prefer to
review both together in one pass, I'm happy to include that work here
instead.

Subject: [PATCH 262/878] refactor: use raw view access in do_append_val_inner
 and consolidate duplicated logic (#22907)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Follow-up to #21794, addressing review feedback from @alamb and
@Dandandan.

## Rationale for this change

In the review of #21794, several optimizations were suggested:

- **@alamb**
([comment](https://github.com/apache/datafusion/pull/21794#discussion_r2174375498)):
"as a possible future optimization, we could use `get_unchecked` here if
it makes any difference" — referring to the slow-path `arr.views()[row]`
access.
- **@alamb**
([comment](https://github.com/apache/datafusion/pull/21794#discussion_r2174376693)):
"from here on down I think this is basically the same as
append_val_inner -- if there are any differences perhaps we can fold it
into append_val_inner and avoid the copy"
- **@Dandandan**
([comment](https://github.com/apache/datafusion/pull/21794#discussion_r2175204095)):
"In principle we can make this faster as well - `extend` + reuse input
view (instead of make_view) + avoid `array.value(row)`"

## What changes are included in this PR?

**1. Refactored `do_append_val_inner` to use raw view access**

Replaced `array.value(row)` + `make_view()` with raw view access via
`get_unchecked(row)`:
- **Inline (len <= 12):** push the u128 view as-is — no decode/re-encode
round-trip
- **Non-inline (len > 12):** parse via `ByteView::from(view)`, copy
buffer data, reuse source prefix directly (avoids re-reading first 4
bytes)

**2. Simplified the vectorized slow path**

Replaced the duplicated 28-line loop body in `vectorized_append_inner`
with `try_reserve` + a loop calling `do_append_val_inner`, eliminating
code duplication.

**3. Removed unused `make_view` import**

### Safety notes

- **`get_unchecked` usage**: Consistent with `do_equal_to_inner` (same
file) and `PrimitiveGroupValueBuilder` in `primitive.rs`, both of which
use the same pattern. All callers derive row indices from enumeration
over the input array length, guaranteeing validity.
- **Buffer access safety**: When `data_buffers()` is empty, all views
must have len <= 12 (Arrow invariant), so the non-inline branch is never
entered.

## Are these changes tested?

Covered by 6 existing unit tests in the `bytes_view` module plus 3
integration tests in the `multi_group_by` module. All 111 tests in the
aggregates suite pass.

## Are there any user-facing changes?

No. This is an internal refactor with no API changes.

Subject: [PATCH 263/878] Make LogicalPlan::Unnest expression/rebuild contracts
 consistent (#22783)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Closes #22769

## Rationale for this change

`LogicalPlan::Unnest` had an inconsistent API contract:
`apply_expressions()` exposed `exec_columns` but `with_new_exprs()`
rejected them via `assert_no_expressions`. This broke the standard
`node.with_new_exprs(node.expressions(), new_inputs)` pattern.

## What changes are included in this PR?

- `with_new_exprs` now accepts expressions from `apply_expressions`
(extracts `Column` values back out)
- `map_expressions` now properly transforms `exec_columns` instead of
treating Unnest as expressionless
- Removed stale comment in `extract_leaf_expressions` (semantic barrier
remains)

## Are these changes tested?

Yes — two new unit tests proving both `with_new_exprs(expressions(),
inputs)` and `with_new_exprs(vec![], inputs)` work. All existing
optimizer and SLT tests pass.

## Are there any user-facing changes?

No.

Subject: [PATCH 264/878] feat: support reading from stdin in datafusion-cli
 (#22839)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #9430.

## Rationale for this change

Users frequently want to pipe data into the CLI, e.g. `cat data.csv |
datafusion-cli`, but pointing `LOCATION` at `/dev/stdin` did not work:

- CSV failed with `Illegal seek` (a pipe is not seekable).
- Parquet failed with `file size of 0 is less than footer` (a pipe
reports size 0).
- JSON silently returned 0 rows.

This PR makes reading from standard input work for CSV, JSON, and
Parquet.

## What changes are included in this PR?

stdin is exposed as a `stdin://` object store, dispatched alongside the
other schemes (`s3`, `gs`, `http`, ...) in `get_object_store` —
conceptually similar to DuckDB's `PipeFileSystem`.

- `rewrite_stdin_location` maps the well-known stdin pseudo-paths
(`/dev/stdin`, `/dev/fd/0`, `/proc/self/fd/0`) to a canonical
`stdin:///stdin.<ext>` URL, so they flow through the normal
object-store/listing code path. The extension matches the declared
`STORED AS` format because the listing layer filters candidate files by
extension.
- The `stdin://` store reads all of standard input into an in-memory
object store. Buffering up front is required because a pipe is not
seekable and Parquet stores its metadata at the end of the file.

Known scope/limitations (left as potential follow-ups):
- Only `CREATE EXTERNAL TABLE` is supported (not dynamic `SELECT * FROM
'/dev/stdin'`).
- Input is fully buffered in memory, so it must fit in memory.
- stdin can only be consumed once per session.
- Unix-only (`/dev/stdin` does not exist on Windows); writing to
`/dev/stdout` is out of scope.

## Are these changes tested?

Yes:
- Unit tests in `object_storage.rs` cover `rewrite_stdin_location` and
end-to-end reads for CSV, JSON, and Parquet via the in-memory store.
- A `#[cfg(unix)]` integration test in `cli_integration.rs` drives the
real binary through an actual pipe, exercising the real stdin read.
- Manually verified all three formats via real pipes, and confirmed
normal local-file reads are unaffected.

## Are there any user-facing changes?

Yes — reading from stdin via `LOCATION '/dev/stdin'` is now supported.
Documented in `docs/source/user-guide/cli/datasources.md` (new "Reading
from standard input" section). No breaking changes.

 ```
 
+## Reading from standard input
+
+On Unix-like systems you can pipe data into the CLI and query it by pointing the
+`LOCATION` at the `/dev/stdin` pseudo-file:
+
+```console
+$ cat hits.csv | datafusion-cli -c "
+CREATE EXTERNAL TABLE hits STORED AS CSV LOCATION '/dev/stdin' OPTIONS ('format.has_header' 'true');
+SELECT count(*) FROM hits;"
+```
+
+This works for CSV, JSON, and Parquet. Because standard input is not seekable
+(and Parquet stores its metadata at the end of the file), the CLI buffers the
+entire input into memory before querying it, so the data must fit in memory.
+Standard input is read only once: the buffered contents are reused for any
+further tables backed by `/dev/stdin` in the same session. Those tables must
+declare the same `STORED AS` format as the first one; a differing format is
+rejected with an error.
+
+The SQL must be passed with `-c`/`--command` or `-f`/`--file` so that standard
+input is free to carry the data. In the interactive shell (and when SQL is
+piped to the CLI without `-c`/`-f`) standard input carries the SQL itself, and
+`LOCATION '/dev/stdin'` returns an error.
+

(<a href="https://github.com/ivov"><code>@​ivov</code></a>)</li>
<li>Setting <code>CI=true</code> normally makes <code>cargo insta
test</code> behave as though <code>--check</code>
was passed. Explicit snapshot handling options such as
<code>--accept</code> now take
precedence over this environment variable, allowing users to override
this
behavior if they want to. <a

<li>Fix <code>cargo insta test --profile</code> being forwarded to
nextest as the nextest
profile instead of the cargo build profile; it now translates to
<code>--cargo-profile</code> for the nextest runner. Add
<code>--nextest-profile</code> to select
the nextest profile. <a
href="https://redirect.github.com/mitsuhiko/insta/issues/910">#910</a></li>
<li>Fix <code>cargo insta pending-snapshots</code> printing unusable
<code>\\?\</code>-prefixed paths
on Windows. The <code>--snapshot</code> filter now also accepts partial
paths: any
trailing path suffix of the snapshot file matches, so a bare
<code>--snapshot my_test.snap</code> works. <a

From 7bb6e152bee1df3cd8215176742bfc1cdf300e52 Mon Sep 17 00:00:00 2001

Subject: [PATCH 266/878] Remove redundant `collect_stat` and
 `target_partitions`  on `ListingOptions` (#22969)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #.

## Rationale for this change

Something that was spotted during the review of:
- https://github.com/apache/datafusion/pull/22657

`ListingOptions::target_partitions` and `ListingOptions::collect_stat`
duplicate `SessionConfig`'s `execution.target_partitions` and
`execution.collect_statistics`.

After some investigation, I think they only live on `ListingOptions` for
historical reasons: when the struct was added (#1010 5 years ago),
`TableProvider::scan` had no access to the session, so the values had to
be copied onto the table at build time. Once #2660 passed `SessionState`
into `scan`, the fields became redundant (and had already drifted —
`scan` read them from the session config while `list_files_for_scan`
read the stale copy). This PR makes `SessionConfig` the single source of
truth.

## What changes are included in this PR?

- Remove `target_partitions`/`collect_stat` fields, their builders, and
`with_session_config_options` from `ListingOptions`.
- `ListingTable` now reads both values from the session config at scan
time.
- Reserve proto tags 8/9 in `ListingTableScanNode` and drop the related
(de)serialization.
- Update benchmarks, factory, and test call sites.

## Are these changes tested?

Yes, by existing tests

## Are there any user-facing changes?

Yes, breaking: the removed fields/builders require configuring

 datafusion.catalog.newlines_in_values false Specifies whether newlines in (quoted) CSV values are supported. This is the default value for `format.newlines_in_values` for `CREATE EXTERNAL TABLE` if not specified explicitly in the statement. Parsing newlines in quoted values may be affected by execution behaviour such as parallel file scanning. Setting this to `true` ensures that newlines in values are parsed successfully, which may reduce performance.
 datafusion.execution.batch_size 8192 Default batch size while creating new batches, it's especially useful for buffer-in-memory batches since creating tiny batches would result in too much metadata memory consumption
 datafusion.execution.coalesce_batches true When set to true, record batches will be examined between each operator and small batches will be coalesced into larger batches. This is helpful when there are highly selective filters or joins that could produce tiny output batches. The target batch size is determined by the configuration setting
-datafusion.execution.collect_statistics true Should DataFusion collect statistics when first creating a table. Has no effect after the table is created. Applies to the default `ListingTableProvider` in DataFusion. Defaults to true.
+datafusion.execution.collect_statistics true Should DataFusion collect statistics when first creating a table. Has no effect after the table is created. Defaults to true.
 datafusion.execution.enable_ansi_mode false Whether to enable ANSI SQL mode. The flag is experimental and relevant only for DataFusion Spark built-in functions When `enable_ansi_mode` is set to `true`, the query engine follows ANSI SQL semantics for expressions, casting, and error handling. This means: - **Strict type coercion rules:** implicit casts between incompatible types are disallowed. - **Standard SQL arithmetic behavior:** operations such as division by zero,   numeric overflow, or invalid casts raise runtime errors rather than returning   `NULL` or adjusted values. - **Consistent ANSI behavior** for string concatenation, comparisons, and `NULL` handling. When `enable_ansi_mode` is `false` (the default), the engine uses a more permissive, non-ANSI mode designed for user convenience and backward compatibility. In this mode: - Implicit casts between types are allowed (e.g., string to integer when possible). - Arithmetic operations are more lenient — for example, `abs()` on the minimum   representable integer value returns the input value instead of raising overflow. - Division by zero or invalid casts may return `NULL` instead of failing. # Default `false` — ANSI SQL mode is disabled by default.
 datafusion.execution.enable_migration_aggregate true Temporary switch for aggregate stream implementations that are being migrated from `GroupedHashAggregateStream`. When set to true, DataFusion tries the migrated implementations when their preconditions are satisfied. When set to false, grouped aggregation falls back to `GroupedHashAggregateStream`. This option will be removed after the migration is finished. See <https://github.com/apache/datafusion/issues/22710> for details.

+### `ListingOptions::target_partitions` and `collect_stat` removed
+
+The `target_partitions` and `collect_stat` fields on
+`datafusion_catalog_listing::ListingOptions`, their builder methods
+(`with_target_partitions`, `with_collect_stat`), and the
+`with_session_config_options` helper have been removed.
+
+`ListingTable` now reads both values directly from the active `SessionConfig`
+at scan time instead of from a copy snapshotted onto the table at construction
+time.
+
+**Who is affected:**
+
+- Code that set `target_partitions` / `collect_stat` per table via
+  `ListingOptions`, or read those public fields.
+- Code that relied on a `ListingTable` freezing these values at construction
+  time independently of the session config. The table now always reflects the
+  current `SessionConfig`.
+
+**Migration guide:**
+
+Configure these on the `SessionConfig` instead:
+
+```rust,ignore
+// Before
+let options = ListingOptions::new(format)
+    .with_target_partitions(8)
+    .with_collect_stat(true);
+
+// After
+let config = SessionConfig::new()
+    .with_target_partitions(8)
+    .with_collect_statistics(true);

Subject: [PATCH 267/878] Refactor outer join null-rejection analysis to track
 join sides directly (#22870)

## Which issue does this PR close?

Closes #22686

## Rationale for this change

`EliminateOuterJoin` makes join elimination decisions using side-level
information (whether the left and/or right side reject NULL-padded
rows), but the existing implementation first collects null-rejecting
columns and then derives side-level booleans by scanning those columns.

This intermediate `Vec<Column>` representation adds indirection and
makes the null-rejection logic for constructs such as top-level `AND`,
nested `AND`, and `OR` harder to follow. This change refactors the
analysis to represent null-rejection evidence directly at the join-side
level while preserving existing optimizer behavior.

## What changes are included in this PR?

* Replace column-based null-rejection tracking with a new private
`NullRejectingSides` helper that records side-level evidence (`left` /
`right`).
* Refactor `extract_null_rejecting_columns` into
`extract_null_rejecting_sides`, returning side-level null-rejection
information directly.
* Simplify `try_simplify_join` to use the returned side-level evidence
without allocating and scanning a `Vec<Column>`.
* Add `union` and `intersection` helpers to model the existing
null-rejection semantics for:

  * top-level `AND` (union of side evidence),
  * `OR` and nested `AND` (intersection of side evidence),
  * other NULL-propagating operators (union of operand evidence).
* Update comments throughout the file to describe the optimizer's
side-level null-rejection contract and the conservative handling of
unsupported or NULL-accepting expressions.
* Leave `eliminate_outer` and join conversion behavior unchanged.

## Are these changes tested?

Yes.

This PR adds unit tests for the new helper behavior:

* `null_rejecting_sides_union`
* `null_rejecting_sides_intersection`

The change is intended to be behavior-preserving and continues to rely
on the existing `eliminate_outer_join` test coverage.

## Are there any user-facing changes?

No.

This is an internal optimizer refactor and comment cleanup intended to
preserve existing query planning behavior.

## LLM-generated code disclosure

This PR includes LLM-generated code and comments. All LLM-generated
content has been manually reviewed and tested.

Subject: [PATCH 268/878] fix: ProjectionPushdown internal error on
 NestedLoopJoin mark joins (#22902)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22901.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

A query whose subquery becomes a mark join (`LeftMark`/`RightMark`) can
panic during the `ProjectionPushdown` physical optimization with an
internal assertion error.

The pushdown helper `try_pushdown_through_join` assumes the join output
schema is the plain concatenation of its two children (`left ++ right`)
and uses `join_table_borders` to split the projected columns into a left
group and a right group by column index. Mark joins break this
assumption: they append an extra `mark` boolean column that does not
originate from either child, so the column-index split misroutes columns
to the wrong side and the subsequent child-projection rewrite fails its
name-match assertion.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

In `HashJoinExec::try_swapping_with_projection` and
`NestedLoopJoinExec::try_swapping_with_projection`, skip the
`try_pushdown_through_join` path for mark joins (`LeftMark`/`RightMark`)
and fall through to embedding the projection into the join instead.

## Are these changes tested?

Yes.

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

Yes, only bug fixes.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 269/878] chore: attach Diagnostic to unary operator type
 errors (#21288)

## Which issue does this PR close?

- Closes #14433

## What changes are included in this PR?

Attaches `Diagnostic` (message, note, help) to the `NOT` and `-` error
paths in `unary_op.rs`. Also extends `Expr::spans()` to recurse through
`Not`/`Negative` so column source locations propagate to the error.

`+` already had this, this PR covers the remaining two operators.

## Are these changes tested?

Yes, added tests in `diagnostic.rs` for column and non-column operands
for both operators.

## Are there any user-facing changes?

Error messages for `NOT <non-boolean>` and `- <non-numeric>` now include
source location and a fix suggestion.

Subject: [PATCH 270/878] fix: Omit NULL values from build side of hash joins
 (#22893)

## Which issue does this PR close?

- Closes #22875

## Rationale for this change

Previously, when the build side of a hash join was backed by an
`ArrayMap`, rows with NULLs in their join keys were omitted, but they
were included for `HashMap`-backed hash joins. Under
`NullEqualsNothing`, we can safely omit rows that have a NULL in any of
their join keys, because they will never contribute to the output of the
join. Omitting NULLs reduces the size of the build-side hash table.

The previous probe behavior also resulted in searching the hash table
for probe rows with NULLs in their join keys. This was wasted work;
indeed, because all NULL build rows will end up in the same hash chain,
this could actually be very expensive for joins over NULL-heavy data
sets. For example, joining two 10k tables on all-NULL join keys took ~6
seconds (!). That drops to a few milliseconds after this PR.

## What changes are included in this PR?

* Omit build rows with one or more NULLs in their join keys from
`HashMap`
* Don't probe the map for probe rows with NULLs in their join keys
* Fix a few places that assumed that an empty build-side hash table
meant the build input was empty
* Add unit tests

## Are these changes tested?

Yes; new tests added.

## Are there any user-facing changes?

No.

Subject: [PATCH 271/878] fix: parquet limit pruning for row group selections
 (#22942)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22941

## Rationale for this change

Limit pruning handled row groups with `RowSelection` incorrectly. It
counted the full row group size and could replace a selection with a
full scan.

## What changes are included in this PR?

- Preserve existing row selections.
- Count only selected rows when checking the limit.
- Add regression tests for both cases.

## Are these changes tested?

Yes. New unit tests cover preserving `RowSelection` and counting
selected rows during limit pruning.

## Are there any user-facing changes?

No API changes.

Subject: [PATCH 272/878] refactor: make scalar distance u64 and overflow aware
 (#22892)

Closes #22687

## Rationale for this change

The distance API in `datafusion/common/src/scalar/mod.rs` previously
returned `Option<usize>`. `usize` is machine-width dependent and does
not represent value-domain cardinality. This could lead to
target-dependent behavior on large integer/temporal ranges.
Additionally, downstream callers like `interval_arithmetic.rs` had to
convert the distance back to `u64` to compute cardinality.

Exposing an overflow-aware `u64`-oriented contract (`distance_u64`)
resolves these architecture differences and aligns the API with
value-domain semantics.

## What changes are included in this PR?

- Added `distance_u64`: Added a new public method `distance_u64(&self,
other: &ScalarValue) -> Option<u64>` to `ScalarValue`.
- Deprecated `distance`: Marked the original `distance(&self, other:
&ScalarValue) -> Option<usize>` method as deprecated and redirected it
to call `distance_u64`.
- Interval Cardinality: Migrated the cardinality calculation in
`datafusion/expr-common/src/interval_arithmetic.rs` to use
`distance_u64` directly.
- Selectivity / Stats Overlap: Migrated the overlap calculations in
`datafusion/common/src/stats.rs` to use `distance_u64`.
- Boundary/Overflow Tests: Added `test_scalar_distance_u64_boundaries`
in `scalar/mod.rs` to verify edge cases:
  - Full signed range edge (`i64::MIN` to `i64::MAX`)
  - Full unsigned range edge (`u64::MIN` to `u64::MAX`)
- Large temporal range edge (`TimestampSecond` and `Date32` boundaries)
- Overflow-to-None behavior (exceeding `u64::MAX` for Float,
`Decimal128`, and `Decimal256` values)

## Are these changes tested?

Yes, they are covered by the new unit tests in `datafusion-common` and
existing test suites in both `datafusion-common` and
`datafusion-expr-common`.

## Are there any user-facing changes?

No, deprecation of `ScalarValue::distance` has been removed from this PR

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Attempt to simplify the `approx_distinct` implementation, the existing
complexity is due to there is no generic API to calculate hash for a
`array.elem(i)`, so we have to implement specialization for many
different types like primitive/string/stringview, and bloated the code
size.

This PR used a existing `create_hashes` for batched hashing that is
applicable to all array types, and it reduced 261 lines of code in
`approx_distinct.rs`

It shows some get 5% faster due to batched hashing, some utf cases get
slower (the worst one 22% slower)

I think it's still a good idea to ignore the regression and simplify the
code due to:

#### Amdahl's Law

If we make function X 20% faster, but function X only takes 1% of query
time, then the complexity to win the performance might not be worthy:
specifically the microbench only measured `update_batch()` function,
this piece of code is highly vectorizable, and it can very unlikely to
be significant on real queries.

I tried to construct a query that is very heavy on `update_batch`, still
can't observe end-to-end difference:

```sql id="8d3m2p"
> select approx_distinct(v1)
from (
select arrow_cast(v1, 'Utf8View')
from generate_series(100000000)
as t1(v1)) as t_string(v1);

+------------------------------+
| approx_distinct(t_string.v1) |
+------------------------------+
| 99201889                     |
+------------------------------+
1 row(s) fetched.
Elapsed 0.139 seconds.

-- Runtime almost the same on PR v.s. main
```

#### LLVM Optimization

For the slowest microbench, I think the root cause is that LLVM can
optimize the manually simplified code more easily.

The existing implementation has the following fast path:


https://github.com/apache/datafusion/blob/b8998c762bb864a9f3607a518384b03dcf40eb61/datafusion/functions-aggregate/src/approx_distinct.rs#L254-L261

The same optimization also exists in the common, simpler API
`create_hashes`:


https://github.com/apache/datafusion/blob/b8998c762bb864a9f3607a518384b03dcf40eb61/datafusion/common/src/hash_utils.rs#L352

The existing implementation is still faster likely because the code is
manually specialized, while `create_hashes` is more branchy. This makes
LLVM easier to figure out how to optimize and bring 20% speedup.

However, this kind of optimization can be applied endlessly and would
introduce complexity everywhere, so I do not think it is worth
preserving here.




## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
1. Extend `create_hashes` with a hash state that is optimized for
statistical quality

Subject: [PATCH 274/878] Unify LRU memory-limiting caches into one generic
 cache (#22613)

## Which issue does this PR close?

- Closes
https://github.com/issues/assigned?issue=apache%7Cdatafusion%7C22359.

## Rationale for this change

This PR introduces a new cache which merges the functionality of
file-metadata cache, list-files cache and file-statistics cache into one
generic implementation. This removes a lot of redundant code.

## What changes are included in this PR?

- Introduce a generic `DefaultCache` with LRU eviction, memory-limit and
TTL.

- Migrate all cache tests to use the new `DefaultCache`.

- Replace file-metadata cache, list-files-cache and
file-statistics-cache implementations with the new generic version.

## Are these changes tested?

Yes. All existing cache tests are migrated to the new implementation and
passing. They had to be slighlty adapted because the new implementation
also counts the cache-key for memory accounting which wasn't the case
for all previous implementations. The tests are still at the same
location to have a diff for reviews.


## Are there any user-facing changes?

The traits `FileStatisticsCache`, `ListFilesCache` and
`FileMetadataCache` are replaced with the types `Cache<TableScopedPath,
CachedFileMetadata>`, `Cache<TableScopedPath, CachedFileList>` and
`Cache<Path, CachedFileMetadataEntry>`.

-/// Default implementation of [`FileStatisticsCache`]
-///
-/// Stores cached file metadata (statistics and orderings) for files.
-///
-/// The typical usage pattern is:
-/// 1. Call `get(path)` to check for cached value
-/// 2. If `Some(cached)`, validate with `cached.is_valid_for(&current_meta)`
-/// 3. If invalid or missing, compute new value and call `put(path, new_value)`
-///
-/// # Internal details
-///
-/// The `memory_limit` controls the maximum size of the cache, which uses a
-/// Least Recently Used eviction algorithm. When adding a new entry, if the total
-/// size of the cached entries exceeds `memory_limit`, the least recently used entries
-/// are evicted until the total size is lower than `memory_limit`.
-///

+### Unify LRU memory-limiting caches into one generic cache
+
+The caches `DefaultFileMetadataCache`, `DefaultListFilesCache` and `DefaultFileStatisticsCache`
+are merged into one generic implementation `DefaultCache`. The corresponding traits are now
+type aliases:
+
+```diff
+- pub trait FileStatisticsCache: CacheAccessor<TableScopedPath, CachedFileMetadata>
+- pub trait ListFilesCache: CacheAccessor<TableScopedPath, CachedFileList>
+- pub trait FileMetadataCache: CacheAccessor<Path, CachedFileMetadataEntry>
++ pub type FileStatisticsCache = dyn Cache<TableScopedPath, CachedFileMetadata>;
++ pub type ListFilesCache = dyn Cache<TableScopedPath, CachedFileList>;
++ pub type FileMetadataCache = dyn Cache<Path, CachedFileMetadataEntry>;
+```
+
+**Who is affected:**
+
+- Users who introduced their own implementation of `FileMetadataCache`, `ListFilesCache` or `FileStatisticsCache`.
+
+**Migration guide:**
+
+Implement the newly introduced types for your custom cache implementation.
+
+See [PR #22613](https://github.com/apache/datafusion/pull/22613) for details.

Subject: [PATCH 275/878] Add StatisticsContext parameter to
 partition_statistics (#21815)

## Which issue does this PR close?

Closes #20184

## Rationale for this change

`ExecutionPlan::partition_statistics` forces each operator to re-fetch
child statistics internally, causing redundant subtree walks in deep
plans.

## What changes are included in this PR?

- Deprecate `partition_statistics` in favor of
`statistics_with_args(&self, args: &StatisticsArgs)`, an extensible
signature that won't require downstream churn when new parameters are
added
- `StatisticsArgs` carries the partition index and a shared per-call
`StatsCache`, eliminating redundant subtree walks within a single
`compute_statistics` call
- Child stats are pre-computed with `partition=None` and cached;
operators look them up via `args.child_stats_of(child)` (overall) or
`args.child_stats_for(child)` (partition-aware)
- Criterion micro-benchmark on three plan shapes from #19795

## Tests

Existing tests pass unchanged. New unit test verifies the caching
contract.

## Test plan

- [x] `cargo fmt --all`
- [x] `cargo clippy --all-targets --all-features -- -D warnings`
- [x] `cargo test --profile ci --all-features` on affected crates
- [x] Criterion benchmark: ~26x (coalesce chain), ~5x (cross-join tree),
~25x (filter chain) speedup

Disclaimer: I used AI to assist in the code generation, I have manually
reviewed the output and it matches my intention and understanding.

+Existing implementations of `partition_statistics` continue to work unchanged.
+The default `statistics_with_args` delegates to the deprecated method, so no
+migration is required until the deprecated method is removed.
+
+> **Warning:** The delegation is **one-way**: the default `statistics_with_args`
+> calls `partition_statistics`, but the default `partition_statistics` does
+> **not** call `statistics_with_args` — it returns `Statistics::new_unknown`.
+> Nodes that override only `statistics_with_args` will silently return
+> `Statistics::new_unknown` to any caller still using the deprecated
+> `partition_statistics`.
+
+**Who is affected:**
+
+- Users who implement custom `ExecutionPlan` nodes (recommended to migrate)
+- Users who call `partition_statistics` directly (recommended to switch to `statistics_with_args`)
+
+**Migration guide:**
+
+For **implementations**, override `statistics_with_args` instead of
+`partition_statistics`. Leaf nodes that do not have children can ignore
+the args.
+
+Child statistics are looked up via `args.compute_child_statistics(child, partition)`.
+Use `args.partition()` for partition-preserving operators, or `None` for
+partition-merging operators that always need overall stats:
+
+```rust,ignore
+// Before:
+fn partition_statistics(&self, partition: Option<usize>) -> Result<Arc<Statistics>> {
+    let child_stats = self.input.partition_statistics(partition)?;
+    // ... transform child_stats ...
+}
+
+// After (partition-preserving):
+fn statistics_with_args(
+    &self,
+    args: &StatisticsArgs,
+) -> Result<Arc<Statistics>> {
+    let child_stats = args.compute_child_statistics(&self.input, args.partition())?;
+    // ... transform child_stats ...
+}
+
+// After (partition-merging):
+fn statistics_with_args(
+    &self,
+    args: &StatisticsArgs,
+) -> Result<Arc<Statistics>> {
+    let child_stats = args.compute_child_statistics(&self.input, None)?;
+    // ... transform child_stats ...
+}
+```
+
+For **callers**, create a `StatisticsArgs` and call `statistics_with_args`
+directly. The cache is created automatically:
+
+```rust,ignore
+use datafusion_physical_plan::StatisticsArgs;
+
+// Before:
+let stats = plan.partition_statistics(None)?;
+
+// After:
+let stats = plan.statistics_with_args(&StatisticsArgs::new())?;
+```
+
 ### `DdlStatement::CreateExternalTable` and `CreateFunction` are now boxed
 
 The two largest variants of `datafusion_expr::DdlStatement` are now

Subject: [PATCH 276/878] bugfix: changed return type of spark's width_bucket
 to i64 (#22811)

## Which issue does this PR close?
- Closes #22602

## Rationale for this change
The return type of this function in Spark is int64. It is changed here
to match Sparks behavior.

## What changes are included in this PR?
Changed the return type of Spark's `width_bucket` from i32 to i64.

## Are these changes tested?
Yes, all existing unit tests in `width_bucket.rs` pass.

## Are there any user-facing changes?
- Spark consumers should expect a different data type when calling the
`width_bucket` function.
- No API changes.

Subject: [PATCH 278/878] feat: warn on NULL equality predicates (#22948)

## Which issue does this PR close?

- Closes #14434.

## Rationale for this change

SQL comparisons such as `expr = NULL` and `expr <> NULL` evaluate to
`NULL` under SQL three-valued logic, not to `true` or `false`. When
those comparisons appear in predicate contexts such as `WHERE`, `JOIN
ON`, or `HAVING`, they are almost always a user mistake where `IS NULL`
or `IS NOT NULL` was intended.

This PR emits non-fatal diagnostic warnings for those cases so callers
that surface `Diagnostic` information can help users find and fix the
query without changing planning success or query semantics.

## What changes are included in this PR?

- Adds warning collection to `SqlToRel`, with
`SqlToRel::take_warnings()` to drain non-fatal planning diagnostics
after planning.
- Adds predicate-scoped detection for `= NULL` and `<> NULL`
comparisons.
- Wires detection into `WHERE`, `JOIN ON`, and `HAVING` planning paths.
- Recursively checks predicate expression structure such as nested `AND`
/ `OR` binary predicates and `CASE WHEN` conditions, without warning for
projection-only expressions like `SELECT col = NULL`.
- Creates `Diagnostic::new_warning` entries with a primary span on the
comparison expression and help pointing at the `NULL` literal when spans
are available.

## Are these changes tested?

Yes. Added regression coverage in
`datafusion/sql/tests/cases/diagnostic.rs` for:

- `WHERE col = NULL`
- `WHERE NULL = col`
- `WHERE col <> NULL`
- `JOIN ... ON col = NULL`
- `HAVING ... = NULL`
- nested `CASE WHEN col = NULL` inside a predicate
- no warning for `IS NULL`
- no warning for projection-only `SELECT col = NULL`
- multiple warnings in one predicate

Validation run locally:

```shell
cargo fmt --all
cargo test -p datafusion-sql --test sql_integration diagnostic
cargo test -p datafusion-sql
cargo clippy -p datafusion-sql --all-targets --all-features -- -D warnings
cargo clippy --all-targets --all-features -- -D warnings
git diff main..HEAD --check
```

## Are there any user-facing changes?

Yes, but non-breaking. SQL planning can now collect warning diagnostics
for likely mistaken `NULL` equality predicates. Consumers can retrieve
them with `SqlToRel::take_warnings()` and decide how to present them.
Planning still succeeds and query semantics are unchanged.

Subject: [PATCH 279/878] feat: support file-level parquet row selections
 (#22940)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22939

## Rationale for this change

- see issue #22939

## What changes are included in this PR?

- Add public `ParquetRowSelection`.
- Add `ParquetAccessPlan::try_new_from_overall_row_selection`.
- Allow Parquet opener setup to read either `ParquetAccessPlan` or
`ParquetRowSelection`.
- Reject using both extension types on the same file.
- Validate that the selection row count matches the file row count.
- Document the new extension path in `ParquetSource`.


## Are these changes tested?

Yes. This PR adds tests for:

- converting a file-level selection into row-group access
- rejecting invalid selection row counts
- creating an initial plan from `ParquetRowSelection`
- rejecting both `ParquetAccessPlan` and `ParquetRowSelection` on the
same file

## Are there any user-facing changes?

Yes. This adds a new public `ParquetRowSelection` type for callers that
want to attach a file-level Parquet `RowSelection` to a
`PartitionedFile`.

Subject: [PATCH 281/878] Add sorted TopK TPC-H benchmark target (#23003)

## Which issue does this PR close?

This PR adds a first-class benchmark target for an existing `sort-tpch`
mode.

## Rationale for this change

`dfbench sort-tpch` already supports TopK queries over input declared as
sorted with `--sorted --limit`, but `bench.sh` only exposed the unsorted
TopK wrapper as `topk_tpch`.

That made the sorted TopK path harder to run from the benchmark bot and
easier to miss during performance work. Adding `topk_sorted_tpch` gives
a named target for the sorted-input TopK case:

```bash
./benchmarks/bench.sh run topk_sorted_tpch
```

The new target uses `--limit 100` so it is the sorted counterpart to the
existing `topk_tpch` benchmark.

## What changes are included in this PR?

- Adds `topk_sorted_tpch` to the benchmark script help text.
- Reuses the existing TPC-H SF1 parquet data setup.
- Adds a `run_topk_sorted_tpch` wrapper around `dfbench sort-tpch
--sorted --limit 100`.
- Writes results to `run_topk_sorted_tpch.json`.
- Documents the new benchmark target in `benchmarks/README.md`.

## Are these changes tested?

Validated with:

```bash
bash -n benchmarks/bench.sh
CARGO_COMMAND=echo DATA_DIR=/tmp/df-topk-bench-data RESULTS_NAME=topk_sorted_tpch_smoke ./benchmarks/bench.sh run topk_sorted_tpch
git diff --check
cargo fmt --all
cargo clippy --all-targets --all-features -- -D warnings
```

The smoke run verified that the script dispatches to:

```bash
dfbench sort-tpch --iterations 5 --path ... --sorted --limit 100
```

## Are there any user-facing changes?

No engine or API behavior changes. This only adds a new opt-in benchmark
target.

-If the TPCH tables have been converted as sorted on their first column (see [Sorted Conversion](#sorted-conversion)), you can use the `--sorted` flag to indicate that the input data is pre-sorted, allowing DataFusion to leverage that order during query execution.
+The `--sorted` flag does not sort or rewrite the input files. It declares that the `lineitem` Parquet input is already sorted ascending by its first column (`l_orderkey`). DataFusion can then leverage that ordering during query execution.

+To generate the expected TPC-H SF=1 Parquet input for this benchmark, run:
+
+```bash

+
+For the `lineitem` table used by `sort-tpch`, this uses `tpchgen-cli` to generate Parquet data that is already ordered by `l_orderkey`. If you use a different input directory, only pass `--sorted` when the `lineitem` files already have that ordering.
 
 Additionally, an optional `--limit` flag is available for the sort benchmark. When specified, this flag appends a `LIMIT n` clause to the SQL query, effectively converting the query into a TopK query. Combining the `--sorted` and `--limit` options enables benchmarking of TopK queries on pre-sorted inputs.

Subject: [PATCH 282/878] test: correct feature gating of two datafusion-common
 tests (#23044)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- N/A — two small, unrelated-to-features test-gating fixes in
`datafusion-common` found while building the crate's tests under
non-default feature sets.

## Rationale for this change

Two `#[cfg]` feature-gating issues in `datafusion-common` test code:

1. **`test_create_hashes_with_quality_hash_state`** asserts that
`create_hashes`
   reproduces a specific high-quality hash distribution. Under the
`force_hash_collisions` feature, `create_hashes` is replaced by a stub
that
writes all-zero hashes, so the exact-value assertion fails — this breaks
the
`cargo test hash collisions` CI job. Every other exact-hash-value test
in
that module is already gated with `#[cfg(not(feature =
"force_hash_collisions"))]`;
   this one was missing the gate.

2. The test-only `use sqlparser::ast::Ident;` in `utils::tests` is used
solely by
`test_quote_identifier`, which is `#[cfg(feature = "sql")]`. Building
the tests
   without the `sql` feature leaves the import unused and emits an
   `unused_imports` warning.

## What changes are included in this PR?

- Gate `test_create_hashes_with_quality_hash_state` with
  `#[cfg(not(feature = "force_hash_collisions"))]`.
- Gate the test-only `Ident` import with `#[cfg(feature = "sql")]` to
match its
  sole user.

Both are test-only changes; no production code is touched.

## Are these changes tested?

Verified via the existing tests:

- With `--features force_hash_collisions`,
`test_create_hashes_with_quality_hash_state`
is now excluded (no longer fails the forced-collision build); without
the
  feature it still compiles and passes.
- Building `datafusion-common` tests without the `sql` feature no longer
emits
the `unused_imports` warning; with `sql` the import and
`test_quote_identifier`
  are both present.

## Are there any user-facing changes?

No.

Subject: [PATCH 283/878] fix: isolate anonymous file statistics cache (#22950)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22935.

## Rationale for this change

Anonymous file reads can read the same path with different explicit
schemas in the same session. The shared file statistics cache was keyed
by table/path metadata, but did not validate that cached statistics
matched the schema used to compute them.

This could reuse narrower cached statistics for a later wider schema
read and panic during statistics projection.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

This PR routes anonymous listing table statistics through a per-table
cache instead of the shared session cache.

Named tables still use the shared session cache, since their table
reference gives the cache a stable identity.

It also adds a regression test that first warms statistics with the
physical schema, then reads the same Parquet file with a wider explicit
schema.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No API Change

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 284/878] fix: Parquet bloom filter pruning can incorrectly
 filter decimals encoded as FIXED_LEN_BYTE_ARRAY (#22995)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22994.

## Rationale for this change

Parquet bloom filter pruning can incorrectly prune decimal columns
encoded as `FIXED_LEN_BYTE_ARRAY`.

Bloom filters are checked against the physical bytes stored in the
Parquet file. For `FIXED_LEN_BYTE_ARRAY`, the byte width comes from the
Parquet column descriptor's `type_length`. DataFusion was checking
decimal literals using a fixed-width integer byte representation, which
can differ from thefile's fixed byte width and cause false negatives.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Carry the Parquet column `type_length` together with the bloom filter
metadata.
- Use `type_length` when checking decimal literals against
`FIXED_LEN_BYTE_ARRAY` bloom filters.
- Fall back to conservative pruning behavior when the fixed byte length
cannot be represented safely.
- Add a regression test for fixed-length decimal bloom filter pruning.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes.

## Are there any user-facing changes?

No API changes. This fixes incorrect query results when Parquet bloom
filter pruning is enabled for fixed-length decimal columns.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 285/878] test: gate hash-dependent approx_distinct tests
 behind not(force_hash_collisions) (#23053)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- N/A — a CI test-gating fix found while building the workspace under
`force_hash_collisions`. Follow-up to #23044, which fixed the equivalent
`datafusion-common` test.

## Rationale for this change

Three `approx_distinct` tests assert exact distinct-count results that
HyperLogLog can only produce with real hashing. Under the
`force_hash_collisions` feature, `create_hashes` forces every hash
equal, so the cardinality estimate collapses to 1 and the assertions
fail — breaking the `cargo test hash collisions` and `extended_tests` CI
jobs:

```
update_batch_nullable_filter_excludes_null_filter_rows
utf8view_groups_short_string_hashed_consistently_across_batches
utf8view_acc_split_batches_match_single_mixed_batch
```

`datafusion-functions-aggregate` did not declare
`force_hash_collisions`, so a plain `#[cfg(not(feature =
"force_hash_collisions"))]` would also raise an `unexpected_cfgs` lint
and never actually fire.

## What changes are included in this PR?

- Forward the feature in `datafusion-functions-aggregate/Cargo.toml`:
`force_hash_collisions = ["datafusion-common/force_hash_collisions"]`,
so the crate recognises it (and it gets enabled under the workspace
`force_hash_collisions` build).
- Gate the three tests (and their test-only imports / helpers) with
`#[cfg(not(feature = "force_hash_collisions"))]`, matching the pattern
already used for the equivalent `datafusion-common` tests.

Test-only changes; no production code is touched.

## Are these changes tested?

- `cargo test -p datafusion-functions-aggregate --features
force_hash_collisions approx_distinct` — the three tests are now
excluded; the rest pass.
- `cargo test -p datafusion-functions-aggregate approx_distinct` (no
feature) — all tests still present and pass.
- `cargo clippy -p datafusion-functions-aggregate --all-targets
--features force_hash_collisions -- -D warnings` — clean.

## Are there any user-facing changes?

No.

Subject: [PATCH 286/878] Skip loading Parquet page index when row-group
 statistics already prove it cannot prune (#22857)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22795

## Rationale for this change

The Parquet opener was loading the page index (ColumnIndex +
OffsetIndex) before row-group statistics pruning. When all surviving row
groups are fully matched by row-group statistics (for example, `IS NOT
NULL` on a non-null column), page index I/O cannot prune further and is
wasted.

## What changes are included in this PR?

- Reorder the opener state machine: `PrepareFilters →
PruneWithStatistics → LoadPageIndex? → LoadBloomFilters`
- Skip `load_page_index` when there is no page-pruning predicate, no
surviving row groups, or every surviving row group is fully matched
- Add unit and integration tests for the gate and the fully-matched `IS
NOT NULL` case

## Are these changes tested?

- `cargo test -p datafusion-datasource-parquet should_load`
- `cargo test -p datafusion-datasource-parquet page_index_skip`
- `cargo test -p datafusion-datasource-parquet
opener::test::test_page_pruning`
- `cargo test -p datafusion --test parquet_integration`
- `cargo clippy -p datafusion-datasource-parquet --all-targets -- -D
warnings`

## Are there any user-facing changes?

No user-facing API changes. This reduces unnecessary Parquet page index
I/O during scan planning when row-group statistics already prove no
further pruning is possible.

Subject: [PATCH 287/878] Return errors on string builder offset overflow in
 `replace` and `initcap` (#22990)

## Which issue does this PR close?

* Part of #22688

## Rationale for this change

`GenericStringArrayBuilder` only exposed infallible append APIs that
panic when string offsets exceed the underlying offset type limits.
String functions such as `replace`, `replace_view`, and the generic
`initcap` path relied on these APIs, meaning extreme output sizes could
panic instead of returning a recoverable `DataFusionError`.

This change introduces fallible builder APIs and migrates selected
string UDFs to use them so offset overflow is reported as an error
rather than causing a panic.

## What changes are included in this PR?

* Add overflow-checked helper functions to `GenericStringArrayBuilder`:

  * `try_offset`
  * `try_push_offset_for_len`
  * `try_append_bytes`
* Add fallible append APIs:

  * `try_append_value`
  * `try_append_placeholder`
  * `try_append_byte_map`
  * `try_append_with`
* Introduce a shared overflow error path that returns a
`DataFusionError` instead of panicking.
* Keep existing infallible append APIs for compatibility while
documenting that new overflow-sensitive call sites should prefer the
`try_*` variants.
* Refactor `replace` and `replace_view` to share a generic
`replace_arrays` implementation.
* Change `apply_replace` to return `Result<()>` and propagate errors
from builder operations.
* Update `replace`/`replace_view` to use the new fallible builder APIs
and thread errors with `?`.
* Update the generic `Utf8`/`LargeUtf8` path in `initcap` to use
`try_append_placeholder` and `try_append_value`.
* Add rollback handling in `try_append_with` so builder state is
restored if offset validation fails.

## Are these changes tested?

Yes.

Added tests in `datafusion/functions/src/strings.rs`:

* `generic_string_builder_try_append_success_path`
* `generic_string_builder_mixed_append_success_path`
* `generic_string_builder_try_offset_overflow`
* `generic_string_builder_try_append_bytes_overflow`

Existing `replace` and `initcap` tests remain in place and the migrated
code paths continue to be exercised by those test suites.

## Are there any user-facing changes?

Yes.

For extreme string outputs that exceed the offset limits of the
underlying string array type, affected functions now return a
`DataFusionError` instead of panicking. Normal behavior and results are
otherwise unchanged.

Subject: [PATCH 288/878] minor: reuse ColumnarValue::into_array in map's
 expand_if_scalar and avoid uncessary clones (#22984)

Follow-up to #22934: per [@alamb's
suggestion](https://github.com/apache/datafusion/pull/22934#issuecomment-4721530629),
reuse the existing `ColumnarValue::to_array` in `map.rs`'s
`expand_if_scalar` instead of hand-rolling the same logic. `to_array`
(borrowing) is used over `into_array` to avoid an extra `ScalarValue`
clone; no behavior change.

Subject: [PATCH 289/878] refactor: add `try_to_proto` / `try_from_proto` to
 `DynamicFilterPhysicalExpr` (#22452)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?
Part of #22434

## What changes are included?
Adds `try_to_proto` and `try_from_proto` to `DynamicFilterPhysicalExpr`
so it participates in the expression-local serialization pattern
introduced in #21929.

The centralized arms in `to_proto.rs` / `from_proto.rs` remain as
fallbacks for now. Cleanup of the pub-for-proto scaffolding
(`from_parts`, `inner`, `original_children`, `remapped_children`) can
follow in a separate PR once decode reads state directly.

## Are these changes tested?
Yes — all three existing dynamic filter roundtrip tests pass:
- `test_dynamic_filter_roundtrip_dedupe`
- `test_dynamic_filter_plan_roundtrip_dedupe`
- `test_dynamic_filter_expression_id_is_stable_between_serializations`

## Are there any user-facing changes?
No.

Subject: [PATCH 290/878] feat: support mixed binary and string types for
 concat UDFs (#22244)

## Which issue does this PR close?

- Closes #12709.

## Rationale for this change

While #21883 introduced binary argument support for the pipe operator,
this PR targets three UDFs: `concat`, `concat_ws`, and Spark's `concat`
to harmonise all their behaviour.

After the first attempt at banning mixed string+concat operations, I
switched to allowing them for concat UDFs and the pipe operator - as
seen in DuckDB, Spark, Databricks. Previously, mixed behaviour was
allowed in #20787 (not released yet). Thus, no breaking API changes
since the klast release

## What changes are included in this PR?

- Added support for binary types (four variants)
- Allow mixed string/binary operations for UDFs and pipe operator
- Fixed edge cases when binary->string type coercion overrode UDF rules,
so mixed calls were allowed
- Refactored the three UDFs by extracting duplicate code into shared
helpers to keep the logic centralised
- Refined `concat_ws` behavior for different separator types

The diff is quite large. Detailed code changes:
- Added a trait `ConcatBuilder` to abstract string/binary/view/array
operations
- Abstracted `StringArray`/`LargeStringArray` into a generic
`ConcatGenericStringBuilder` - less duplication
- Introduced mirrored builders for binary types in a new file
`binaries.rs`
- Introduced more `ColumnarValueRef` variants to handle nullable and
non-nullable binary types
- Extracted the ColumnarValue -> ColumnarValueRef builder to
`from_columnar_value` - simplified call sites. Scalar code path stays
mostly the same
- Switched from `Signature::variadic` to `Signature::UserDefined` to
allow different argument types.`Variadic` required every argument
(including binaries) to be coerced to the same string type, so the UDF
cannot distinguish between binary and string inputs. It's a relatively
uncommon - happy to discuss
- Simplified Spark's concat significantly by reusing the `concat`
implementation, so it handles only Spark-specific null-handling
- Moved SLTs from Spark SLT (`spark/concat.slt`) to a generic SLT, so we
test both generic and Spark-specific behaviour


## Are these changes tested?

- Added more unit tests for previously uncovered major code paths
- Added more SLTs, especially for type coercion

## Are there any user-facing changes?

No. Also, reverted a breaking api change for `||` operator

Subject: [PATCH 291/878] minor: Validate `batch_size` configuration when
 setting it (#23054)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of https://github.com/apache/datafusion/issues/17498

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
In datafusion-cli:
```
DataFusion CLI v53.1.0
> set datafusion.execution.batch_size=0;
0 row(s) fetched.
Elapsed 0.001 seconds.
```

A '0' batch_size is a invalid config value, and it's widely used in most
operators to control behavior. If operators don't validate `batch_size`,
the 0 value might cause bugs/panics. This PR rejects it when setting the
config.

I triggered a bug on my first attempt:
```
> set datafusion.execution.batch_size=0;
0 row(s) fetched.
Elapsed 0.000 seconds.

> select * from generate_series(100);
+-------+
| value |
+-------+
+-------+
0 row(s) fetched.
Elapsed 0.004 seconds.
```

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
Implement a custom type for non-zero usize configuration value on
`batch_size`, and rejects '0' value on initialization. Rust native
`NonZero<u32>` is not used, because custom type allows to provide better
error message on errors, and the implementation complexity is similar.

Note other invalid inputs like '-1' 'a' are already rejected and covered
by existing tests.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
3. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Yes, sqllogictest

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No

Subject: [PATCH 292/878] Fix shared TopK early exit with shared prefix
 threshold (#22991)

## Which issue does this PR close?

Closes #22874.

Follow-up to [fix(topk): call attempt_early_completion when filter
rejects entire batch].

## Rationale for this change

[TopK dynamic filter pushdown attempt 2] lets `SortExec` tighten
scan-side predicates while a TopK heap finds better rows. Once the
current TopK threshold is known, scans can skip data that cannot enter
the final `ORDER BY ... LIMIT` result.

That works well for a single partition. Partitioned `SortExec` has one
extra case to handle:

- each output partition has its own local `TopK` heap
- those local heaps share one `TopKDynamicFilters` instance
- one partition can tighten the shared filter before another partition
has enough rows to fill its local heap

[fix(topk): call attempt_early_completion when filter rejects entire
batch] fixed the local case where a heap already has a max row and the
dynamic filter rejects a whole batch.

This PR fixes the remaining shared-filter case. A lagging partition can
now use the shared prefix threshold to stop early even when its local
heap is still empty. If there is no shared threshold yet, it falls back
to the existing local heap prefix check.

The shared prefix check is not treating another partition's threshold as
this partition's local heap boundary. It uses the same threshold that
already drives the shared dynamic filter. Once a partition's ordered
input has moved past that shared prefix threshold, later batches from
that partition cannot add rows that survive the shared filter. The local
heap still emits the candidates it has already kept; this only stops
pulling input that can no longer add candidates.

Single-partition behavior is unchanged.

## How the TopK optimizations fit together

There are two existing optimizations involved here:

- Dynamic filter pushdown: once a `TopK` heap has K rows, its worst kept
row becomes a threshold. That threshold tightens a scan-side filter so
later data that cannot enter the final `ORDER BY ... LIMIT` result can
be skipped.
- Prefix early exit: when the input is ordered by a prefix of the
requested sort, `TopK` can stop pulling once the last row in a batch is
past a known TopK boundary on that shared prefix.

For a partition-preserving `SortExec`, those optimizations meet in one
shared place. Each output partition has a local `TopK` heap, but all of
those local heaps publish into one shared dynamic filter. A partition
that fills first can tighten the shared filter for everyone else.
Lagging partitions then need to use that same shared prefix threshold to
stop pulling once their ordered input has moved past it.

This PR makes that composition explicit: the shared filter stays alive
until every local `TopK` has emitted, and the shared threshold carries
its common-prefix row so lagging partitions can apply the same prefix
early-exit check.

## What changes are included in this PR?

- Check early completion when a batch passes the dynamic filter but
produces zero heap replacements.
- Track local TopK emitters so a shared filter completes only after the
last emitter has produced output.
- Store the shared threshold and its common-prefix row together in
`TopKDynamicFilters`.
- Check the shared prefix in `attempt_early_completion` before falling
back to the local heap prefix.
- Add focused TopK and `SortExec` tests for the local zero-replacement
path, early completion before local heap fill, equal-prefix
non-completion, DESC/null prefix ordering, and shared-filter completion.

## How is this split for review?

The commits are ordered so each one has a narrow job:

1. `Check TopK early completion after zero-replacement batches`
Handles the local case where a batch passes the dynamic filter, produces
zero heap replacements, but still proves later rows cannot enter the
TopK.

2. `Complete shared TopK filters after all emitters`
Keeps a shared dynamic filter watchable until every local TopK emitter
has emitted. This includes the `SortExec` wiring for preserved
partitioning.

3. `Use shared TopK prefix thresholds for early exit`
Carries the shared threshold's common-prefix row so lagging partitions
can stop before their local heap is full.

## Are these changes tested?

Correctness is covered by targeted tests for:

- the local zero-replacement early-completion path
- early completion before local heap fill from a shared prefix threshold
- equal-prefix non-completion
- DESC and NULLS LAST prefix row ordering
- shared-filter completion after all TopK emitters, including preserved
`SortExec` partitioning

Relevant background:

- [perf: Add TopK benchmarks as variation over the `sort_tpch`
benchmarks] added the benchmark setup used here.
- [perf: Introduce sort prefix computation for early TopK exit
optimization on partially sorted input (10x speedup on top10 bench)]
added common-prefix TopK early termination.
- [TopK dynamic filter pushdown attempt 2] added scan-side dynamic
filter pushdown and exposed the shared-filter / local-heap interaction.
- [fix(topk): call attempt_early_completion when filter rejects entire
batch] fixed the local all-filtered-batch case.
- This PR fixes the remaining partitioned shared-filter case.

Benchmark command:

```bash
dfbench sort-tpch --sorted --limit 10 --iterations 5 \
  --path /tmp/df-topk-bench-data/tpch_sf1 \
  -o /tmp/topk-shared-prefix-followup.json
```

Both sides were rebuilt with fresh isolated `release-nonlto` target
directories before running the benchmark. This is not the regular
`topk_tpch` script: this case needs `--sorted --limit 10` to exercise
the prefix early-exit path.

Clean rerun against the PR base commit `7bb6e152b`. Times are
milliseconds, using the average of 5 iterations for each row.

| Q9 | 92.13 | 10.27 | -88.8% |
| Q10 | 89.66 | 14.35 | -84.0% |

The `DataSourceExec` counters show the less noisy part of the result.
Q8/Q9/Q10 now emit only the first batch from each partition instead of
continuing to drain millions of rows.

## Are there any user-facing changes?

No. This is an internal physical execution optimization fix.

Subject: [PATCH 293/878] feat(parquet): intra-file early stopping via
 statistics + dynamic filters (#22450)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Closes #22407.

## Rationale for this change

DataFusion already prunes parquet at three granularities — **file**
(`EarlyStoppingStream` + `FilePruner`), **row group at scan-startup**
(`PruningPredicate` → `RowGroupAccessPlanFilter`), and **row inside an
open RG** (`RowFilter`).

There's a gap in the middle: once row-group pruning runs at file open,
that
decision is **frozen** because any dynamic filter is still `lit(true)`
at
that point. As `TopK` tightens its threshold at runtime, subsequent RGs
in
the already-opened file keep getting decoded even when their stats
already
prove they cannot beat the threshold. This is the dominant cost for
`ORDER BY ... LIMIT` queries on multi-RG files where file-level pruning
can't help (single large file, or scrambled-RG multi-file).

See the issue for a full architectural diagram and a concrete trace
showing where the wasted I/O / decompression / decode lives.

## What changes are included in this PR?

A single decoder paused at row-group boundaries, with a pruner consulted
between row groups and the decoder rebuilt via `into_builder()` to skip
the row groups the pruner just rejected. Three coordinated pieces:

1. **`RowGroupPruner`**
(`datafusion/datasource-parquet/src/push_decoder.rs`)
   mirrors `FilePruner` at row-group granularity. It uses the
   `DynamicFilterTracker` API from #22460 to subscribe once to every
   not-yet-complete dynamic filter in the predicate; `tracker.changed()`
   is a single atomic load — no tree traversal per check. The cached
   `PruningPredicate` is rebuilt only when a watched filter has actually
   moved, then evaluated against the next pending row group's statistics
   via the existing `RowGroupPruningStatistics` adapter. Predicate
   construction errors and predicate evaluation errors are counted into
   two separate metrics so a flaky predicate path can never silently
   drop data.

2. **Single-decoder iteration model**
   (`PushDecoderStreamState::transition`). The opener builds **one**
   `ParquetPushDecoder` from the prepared access plan, and the stream
   uses arrow-rs 59's `ParquetRecordBatchReader` iterator to pause at
   row-group boundaries. At each boundary the pruner is consulted
   against the head of `rg_plan` (the remaining row-group indices). If
   the pruner proves the head RG unwinnable, that index is dropped from
   the plan and the decoder is **rebuilt via**
   `decoder.into_builder().with_row_groups(remaining).build()` so the
   skipped RGs are bypassed entirely — no decode, no row-filter eval.
   Already-fetched buffered bytes for downstream RGs carry across the
   rebuild.

3. **Gate: build the pruner only when the predicate actually moves.**
   The opener creates a `RowGroupPruner` only when
   `DynamicFilterTracking::classify(&predicate)` reports `Watching` (at
   least one not-yet-complete dynamic filter) **and** more than one row
   group remains in the access plan. Static or already-complete
   predicates were fully consumed by `prune_by_statistics` at file open,
   so re-evaluating them per RG boundary would be wasted work.

The earlier multi-decoder design (`PendingDecoderRun`,
`ParquetAccessPlan::split_runs`, `force_per_row_group`) is removed —
arrow-rs 59's `into_builder` + `with_row_groups` makes a single decoder
strictly more capable.

### Observability

- New `Count` metric `row_groups_pruned_dynamic_filter` on
  `ParquetFileMetrics` surfaces the runtime saving.
- New `dynamic_rg_pruning=eligible` marker on `ParquetSource`'s
  `EXPLAIN` (`fmt_extra` Default + Verbose) signals plan-time
  eligibility, emitted whenever the predicate has a still-watching
  dynamic portion. **Eligible** rather than **true** because the static
  plan can't predict the runtime outcome.

### Benchmarks (`benchmarks/sort_pushdown_inexact`, 5 iterations)

| Query | main | this PR | Δ |
|---|---|---|---|
| Q1 `ORDER BY l_orderkey DESC LIMIT 100` | 6.99 ms | 3.80 ms | **−46%**
|
| Q2 `ORDER BY l_orderkey DESC LIMIT 1000` | 3.29 ms | 1.33 ms |
**−60%** |
| Q3 `SELECT * ... DESC LIMIT 100`         | 11.17 ms | 9.91 ms | −11% |
| Q4 `SELECT * ... DESC LIMIT 1000`        | 9.28 ms | 7.95 ms | −14% |

Narrow-projection queries gain the most — their per-RG cost is dominated
by metadata + sort-column read, which this PR eliminates for unwinnable
RGs. Wide-projection queries gain less because the *kept* RG's
all-column decode dominates total time, but still see meaningful
savings.

## Are these changes tested?

Three layers:

- **6 unit tests**:
  - 3 in `push_decoder.rs::tests`: `RowGroupPruner` basic pruning,
    tracker-driven dynamic-filter updates, fallback when the predicate
    has no analyzable bounds.
  - 3 in `source.rs::tests`: `dynamic_rg_pruning=eligible` marker
    present on dynamic predicate, absent on static predicate, absent
    when there is no predicate at all.
- **3 integration tests** in
  `datafusion/core/tests/parquet/dynamic_row_group_pruning.rs`:
  asserts `row_groups_pruned_dynamic_filter >= 1` end-to-end on a 5-RG
  `ORDER BY DESC LIMIT 5` scan; a regression test for the
  `prepare_access_plan` reorder bug that uses `ORDER BY ASC` against a
  file written in descending value order so the sort-pushdown reorder
  is exercised; and a quiet-without-TopK test that asserts the metric
  stays at 0 (no spurious firing).
- **New SLT**
  `datafusion/sqllogictest/test_files/dynamic_row_group_pruning.slt`:
  asserts both `EXPLAIN` surfaces — plain `EXPLAIN` shows
  `dynamic_rg_pruning=eligible`, and `EXPLAIN ANALYZE` pins
  `row_groups_pruned_dynamic_filter=4` (five RGs, four pruned at
  runtime).

`cargo clippy --all-targets --all-features -- -D warnings` clean.

## Are there any user-facing changes?

Two visible additions, both opt-in via existing dynamic-filter
infrastructure:

- New `row_groups_pruned_dynamic_filter` counter visible in
  `EXPLAIN ANALYZE` for queries whose plan carries a
  `DynamicFilterPhysicalExpr` (today: only TopK with
  `enable_topk_dynamic_filter_pushdown=true`, which is the default).
- New `dynamic_rg_pruning=eligible` marker visible in `EXPLAIN`
  output for the same queries.

No config changes, no API breakage, no behavior change for queries
without a dynamic predicate.

+//! End-to-end test for **runtime row-group pruning** driven by a TopK
+//! `SortExec`'s `DynamicFilterPhysicalExpr`.
+//!
+//! A 5-row-group parquet file is constructed with disjoint statistics on
+//! the sort column (`v`): row group `i` contains values
+//! `[i*100, (i+1)*100)`. The query `ORDER BY v DESC LIMIT 5` fills the
+//! TopK heap from the row group with the largest values; the threshold
+//! then proves the remaining row groups cannot contribute. The runtime
+//! `RowGroupPruner` in the parquet scan must observe the tightened
+//! threshold and increment `row_groups_pruned_dynamic_filter`.
+//!
+//! We assert a property (`pruned >= 1`) rather than an exact count
+//! because batch-arrival timing affects how soon the TopK heap fills,
+//! and we don't want this test to become flaky.

Subject: [PATCH 294/878] feat(unparser): support DISTINCT FROM operators in
 the MySQL dialect (#22999)

## Which issue does this PR close?

Closes #22997

## Rationale for this change

MySQL does not support the `IS NOT DISTINCT FROM` syntax, but has an
alternative syntax which does the same, the spaceship operator.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Adds a `DistinctFromStyle` attribute to dialects that dictates how `IS
DISTINCT FROM` is unparsed.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes

## Are there any user-facing changes?

No, we provide a default implementation for `DistinctFromStyle`

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 296/878] bench: add correlated-proxy case to the
 predicate_eval suite (#22919)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Related to #11262 (predicate evaluation ordering). Extends the
`predicate_eval`
  suite added in #22704. No single issue closed.

## Rationale for this change

The `correlation` subgroup's existing cases (q70–q72) use two predicates
of equal
cost and equal selectivity. For two conjuncts the evaluation cost of an
order is
`cost(first) + selectivity(first) × cost(second)`, which is symmetric
here — so
the two orders cost the same and correlation only affects the result
cardinality.
These cases measure the *overhead* of an ordering system, but give it no
opportunity: nothing in the suite rewards (or even detects)
correlation-aware
ordering.

This adds a case with real, measurable headroom that **only** joint
statistics can
find. A cheap integer predicate (`c0 = 1`, ~30%) is a perfect proxy for
three
string regexes (on `s1`/`s2`/`s3`); a fourth regex (on `s4`) has the
same ~30%
selectivity and the same cost but is independent. The four string
columns are
deliberately **identical in shape** — equal width, one marker at the
same offset,
an equally cheap regex each — so marginally the four regexes are
indistinguishable
in *any* position: neither a per-predicate cost/selectivity estimate nor
runtime
timing can prefer one over another. Conditionally — behind the proxy —
the three
correlated regexes keep every survivor while the `s4` regex still
discards ~70%.

The query is written in the natural-but-pessimal order (the redundant
regexes
grouped with their proxy, the informative one last). On an M-series
laptop the
written order runs ~1.7x slower than the hand-optimal order `[c0, s4,
s1/s2/s3]`
(16.5 ms vs 9.7 ms median per iteration), so:

- an ordering system using *marginal* per-predicate statistics (or an
independence assumption) is blind to the difference — every ranking of
the four
  regexes looks equivalent;
- a system measuring the predicates' *joint* behaviour can reliably
collect ~1.7x.

## What changes are included in this PR?

- `load/corrproxy.sql` — the correlated-proxy dataset (deterministic,
generated
from `generate_series` like the existing datasets;
`PRED_ROWS`/`PRED_FILL`
knobs as elsewhere). The proxy and independent conditions are factored
into a
`WITH base` CTE as named booleans so each invariant has a single
definition.
- `queries/correlation/q73.sql`, `benchmarks/correlation/q73.benchmark`
— the new
  case, following the suite's existing conventions.

Run with: `BENCH_NAME=predicate_eval BENCH_SUBGROUP=correlation cargo
bench --bench sql`

## Are these changes tested?

The suite's shared template asserts the query returns rows; the case
runs green
locally alongside q70–q72. The dataset invariants were verified on 1M
rows: equal
column widths (63), marginal selectivities all ~0.30, and
conditional-on-`c0`
selectivity 1.0 for `s1`/`s2`/`s3` vs ~0.30 for `s4`.

## Are there any user-facing changes?

No — benchmark-only.

Subject: [PATCH 297/878] fix: prevent unparser stack overflow on deeply nested
 expressions (#23058)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23056.

## Rationale for this change

`Unparser::expr_to_sql` overflows the OS stack on deeply nested
expressions, and — surprisingly — it does so **even with the
`recursive_protection` feature enabled** (the default for the
`datafusion` crate).

While investigating I found the root cause is subtler than "a function
is missing `#[recursive]`":

`expr_to_sql_inner` **is** already annotated and **is** re-entered on
the function-argument / dialect-override paths, so the trampoline does
fire. The real problem is that the `recursive` crate's default red zone
is **128 KiB**, but a single `expr_to_sql_inner` stack frame in debug
builds is **~130 KiB** — *larger than the red zone*.
`stacker::maybe_grow` only grows when `remaining < red_zone`, so a frame
can pass the check and then overflow before the next checkpoint. The
unparser installed **no `StackGuard`**, unlike the planner, which
already does exactly this in `query.rs`:

```rust
// query.rs
let _guard = StackGuard::new(256 * 1024);
```

with a comment noting the same debug-frame-size issue (PR #13310).

Secondary leaks: several internal recursion sites recursed through the
public, un-annotated `expr_to_sql` (function arguments, `make_array`,
`array_element`, `named_struct`, `map`, and the `array_has` /
`date_part` dialect overrides), and `remove_unnecessary_nesting` (pretty
mode) was not annotated at all — it would be the next overflow site once
the first is fixed.

## What changes are included in this PR?

The recursive design is kept (an iterative rewrite of the tree-building
unparser would be a large, high-risk change for no benefit over the
trampoline). The fix mirrors the planner:

- Install `StackGuard::new(256 * 1024)` once at the top-level
`expr_to_sql`.
- Add an annotated `pub(crate) expr_to_sql_with_nesting` recursion core
that all internal recursion sites call. This keeps pretty-mode behavior
identical (each level still runs `remove_unnecessary_nesting`) while
making every nesting level a stack-growth checkpoint.
- Annotate `remove_unnecessary_nesting` with `#[recursive]`.

The PR is split into two commits for review: the failing regression test
first, then the fix.

## Are these changes tested?

Yes. `test_deeply_nested_expr_does_not_overflow_stack` (gated on
`recursive_protection`) unparses a depth-2000 `array_has` chain on
`PostgreSqlDialect` and a depth-2000 binary chain on a 2 MiB thread. It
aborts the process on `main` and passes with the fix. I verified
empirically that with the default 128 KiB red zone the test still
aborts, and that 256 KiB carries both paths past depth 5000 on a
realistic thread.

Note: the guarantee holds on realistically-sized thread stacks (≥1–2
MiB). The 512 KiB-stack figure in the issue's repro is too small to
bootstrap the heavier `array_has` override path even after the fix, but
that is the same memory floor the planner side has and is not a
configuration used by DataFusion in practice.

## Are there any user-facing changes?

No public API changes. Deeply nested expressions that previously aborted
the process now unparse successfully when `recursive_protection` is
enabled.

Subject: [PATCH 298/878] refactor: name build-row and matchable-map presence
 checks in hash join (#23024)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23008.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`HashJoinStream::state_after_build_ready` relies on two *different*
facts about the collected build side:

- whether the build side physically has rows (`batch().num_rows()`)
- whether the hash map has any matchable entries (`map().is_empty()`)

These diverge under `NullEquality::NullEqualsNothing`: build rows whose
join key is NULL are omitted from the map, so the map can be empty while
the build side still has rows. Conflating the two was the source of the
bug fixed in #22893.

Today both checks are written inline as raw `batch().num_rows() == 0` /
`map().is_empty()`. Giving each a name on `JoinLeftData` makes the
distinction explicit at the API surface, so future call sites are harder
to get wrong.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add two helpers on `JoinLeftData`:
  - `has_build_rows()` — build-side row presence
  - `has_matchable_build_rows()` — matchable hash-map entry presence
- Update `state_after_build_ready` to use them instead of the raw
checks.

Pure readability refactor — no behavior change.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Covered by the existing hash join tests; `cargo test -p
datafusion-physical-plan hash_join` passes (804 tests). Since this is a
readability-only refactor with no behavior change, no new tests are
added.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
No.

Subject: [PATCH 299/878] IN LIST: clean up generic static filtering (#21927)

## Which issue does this PR close?

- Part of #19241.
- This PR was originally proposed as the first commit in the broader `IN
LIST` optimization series in #19390.
- This PR builds on the refactor extracted in #21649.

## Rationale for this change

After #21649, non-primitive constant `IN LIST` evaluation still uses the
extracted `ArrayStaticFilter` fallback path. That path relies on
comparator checks for each input row. This PR replaces that fallback
lookup with a precomputed hash table and shared result construction so
generic constant-list evaluation is cheaper before the later specialized
primitive and string optimizations from #19390.

## What changes are included in this PR?

The PR is split so reviewers can separate mechanical cleanup from the
behavior/performance changes:

1. `Refactor generic InList static filter helpers`

Pure refactoring. This moves the existing generic static-filter
construction and probe loop into helper methods inside
`ArrayStaticFilter`, without changing the lookup data structure or
result semantics.

2. `Build InList results from bitmaps`

Changes how the generic path materializes `BooleanArray` results after
membership has been computed. Instead of mixing membership checks and
SQL three-valued null handling in the row loop, this builds a contains
bitmap first and applies the null/negation rules with bitmap operations.
This keeps the same `IN` / `NOT IN` semantics, including the `NULL`
cases.

3. `Optimize generic InList static filtering`

Replaces the fallback lookup storage from a unit-valued raw-entry
`HashMap` to `hashbrown::HashTable<usize>`. The table still stores
indices into the constant list and still uses Arrow hashing plus
`make_comparator` for equality, but avoids the extra map value
bookkeeping.

The existing specialized primitive filters and dictionary handling are
intentionally left out of scope.

## Are these changes tested?

Yes.

## Are there any user-facing changes?

No. This is an internal performance optimization only.

## Local benchmark snapshot

Benchmark command:

```bash
cargo bench -p datafusion-physical-expr --profile release-nonlto --bench in_list_strategy -- --save-baseline <name>
```

Method: compare adjacent saved baselines using raw Criterion sample
minima (`min(time / iters)`). Lower is better; changes within +/-5% are
treated as noise.

Compared baselines: merge-base ->
[#21927](https://github.com/apache/datafusion/pull/21927)

Relevant scope: generic fallback string/view/binary rows.

Summary: 62 relevant rows, 61 faster, 0 slower, 1 within +/-5%.

Subject: [PATCH 300/878] docs: clarify stdin store buffers on construction,
 not first use (#23060)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Follow-up to #22839 (stdin support in `datafusion-cli`), addressing
post-merge review feedback from @alamb. No separate issue.

## Rationale for this change

In the review of #22839, @alamb noted that the
`StdinUtils::get_or_create` doc comment was technically imprecise:

> technically I would say this buffers stdin on construction, not first
use.

The `stdin://` store reads and buffers all of standard input eagerly
when the store is constructed (`object_store` → `read_to_end` →
`in_memory_object_store`), not lazily on first use of the store. The doc
comment said "on first use", which suggests lazy buffering.

## What changes are included in this PR?

Reword the first sentence of the `get_or_create` doc comment to say the
store buffers all of standard input "when the store is first
constructed" instead of "on first use". Doc-comment only; no behavior
change.

## Are these changes tested?

No code change — documentation only. Existing tests in
`object_storage/stdin.rs` are unaffected.

## Are there any user-facing changes?

No.

Subject: [PATCH 301/878] test: drive stdin store reuse through get_or_create
 (#23061)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Follow-up to #22839 (stdin support in `datafusion-cli`), addressing
post-merge review feedback from @alamb. No separate issue.

## Rationale for this change

In the review of #22839, @alamb noted the `reuses_buffered_stdin_store`
test would be clearer if it used the same API to create and re-fetch the
object store:

> this test would be clearer for me if it used the same API to create
and recreate the object store -- aka `StdinUtils::get_or_create` rather
than `StdinUtils::in_memory_object_store`

The test built the buffered store via
`StdinUtils::in_memory_object_store` but re-fetched it via
`StdinUtils::get_or_create`, which obscured what "reuse" actually
guarantees.

## What changes are included in this PR?

Refactor `reuses_buffered_stdin_store` so the only `StdinUtils` API it
exercises is `get_or_create`:

- Seed the registry with a plain `InMemory` store. The genuine first
stdin read happens inside `get_or_create` → `object_store`, which
consumes the real process stdin and so cannot be driven from a unit
test; the comment now explains this.
- Assert via `Arc::ptr_eq` that `get_or_create` hands back that *exact*
store rather than rebuilding it — a stronger and clearer statement of
the reuse invariant than comparing bytes alone.

Test-only change; no production behavior change.

## Are these changes tested?

Yes — this is a test change. Verified locally:

```
cargo test -p datafusion-cli --lib object_storage::stdin
...
test object_storage::stdin::tests::reuses_buffered_stdin_store ... ok
test result: ok. 7 passed; 0 failed; 0 ignored; 0 measured; 62 filtered out
```

## Are there any user-facing changes?

No.

Subject: [PATCH 302/878] test: Move default cache tests to default cache file
 (#23040)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes None.

## Rationale for this change

Follow-up of https://github.com/apache/datafusion/pull/22613 This moves
the cache related tests to `default_cache.rs` where the tests belong to.
The tests were previously not moved to have a diff for the review. Now,
since https://github.com/apache/datafusion/pull/22613 is merged we can
move the tests to the right location.

## What changes are included in this PR?

See above.

## Are these changes tested?

This change only moves tests around.

## Are there any user-facing changes?

No.

Subject: [PATCH 303/878] feat: Add new `input_file_name` UDF for file-backed
 scans (#22978)

## Which issue does this PR close?

- Closes #6051.
- Closes https://github.com/apache/datafusion/pull/20071
- Part of #20135.

## Rationale for this change

Adds useful metadata functions to DataFusion. This PR builds on
@ethan-tyler's #20071.

## What changes are included in this PR?

1. A new `input_file_name()` UDF, which reports a UTF8 return_type. Like
`file_row_index()`, it errors when evaluated out of context.
2. Add rewrites in the `FileOpener` (Both in `ParquetOpener` and
`ProjectionOpener`), making it a literal with the file's path.
3. New public rewrite helper `rewrite_input_file_name_in_projection` in
`datafusion-physical-expr-adapter`.

## Are these changes tested?

1. Unit tests in all rewrite-sites and for the core rewrite logic
2. New SLT tests working on CSV
3. New SLT testing metadata functions specifically on Parquet which has
its own opener. These include `file_row_index()`.

## Are there any user-facing changes?
- The new UDF
- New public function in `datafusion-physical-expr-adapter` -
`rewrite_input_file_name_in_projection`.

AI was used in this PR, mostly when helping to come up with test cases.

+### `input_file_name`
+
+Returns the path of the input file that produced the current row.
+
+Note: file paths/URIs may be sensitive metadata depending on your environment.
+
+This function is intended to be rewritten at file-scan time (when the file is
+known). If the input file is not known (for example, if this function is
+evaluated outside a file scan, or was not pushed down into one), direct evaluation returns an error.
+
+```sql
+input_file_name()
+```
+
+#### Example
+
+```sql
+SELECT input_file_name() FROM t;
+```
+
 ### `try_cast_to_type`
 
 Casts the first argument to the data type of the second argument, returning NULL if the cast fails. Only the type of the second argument is used; its value is ignored.

Subject: [PATCH 304/878] Optimize Parquet row-filter struct schema pruning
 (#22960)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
`build_filter_schema and `prune_struct_type` repeatedly scanned the same
struct-field access paths while constructing Parquet row-filter
projection schemas. That caused avoidable iterator work and temporary
allocations when filters referenced multiple struct fields, especially
across nested struct paths.

This change groups struct field access paths once per schema level, so
schema pruning can reuse lookups instead of repeatedly filtering the
full access-path list.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
* Group struct field access paths by root column in build_filter_schema.
* Reuse the grouped root-path lookup when deciding whether to keep a
full field or prune a struct field.
* Group recursive struct pruning paths by field name in
prune_struct_type.
* Avoid rebuilding per-field temporary vectors while walking struct
fields.
* Preserve whole-field output when an access path terminates at that
field.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
* cargo fmt --all
* cargo clippy -p datafusion-datasource-parquet --all-targets
--all-features -- -D warnings
* cargo test -p datafusion-datasource-parquet row_filter

## Are there any user-facing changes?

No

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 305/878] fix: block timestamp precision narrowing unwrap
 (#22837)

## Which issue does this PR close?

Part of https://github.com/GreptimeTeam/greptimedb/issues/8214.
Follow-up / smaller alternative to #21908. So this quick fix is for fix
a very common path, the rest(and the allow list version still lays in
#21908 and need more discussion)

- closes https://github.com/apache/datafusion/issues/22142

## Rationale for this change

`unwrap_cast` can currently rewrite predicates like:

```sql
CAST(ts_ns AS timestamp(3)) = timestamp(3) '2024-01-01 00:00:00.001'
```

into an equality against the original nanosecond column. That is not
equivalent: the original predicate matches every nanosecond timestamp
within the same millisecond, while the rewritten predicate only matches
the exact millisecond boundary.

## What changes are included in this PR?

This is intentionally a small blocklist-only fix:

- add a shared `is_timestamp_precision_narrowing_cast` helper
- block comparison cast unwrap when a timestamp cast narrows precision
- apply the same guard to logical and physical unwrap-cast simplifiers
- keep timestamp precision widening unwraps enabled

## Are these changes tested?

Added targeted logical, physical, and helper tests.

Ran:

```text
cargo test -p datafusion-optimizer unwrap_cast
cargo test -p datafusion-physical-expr unwrap_cast
cargo test -p datafusion-expr-common test_timestamp_precision_narrowing_cast
```

## Are there any user-facing changes?

Plans will keep timestamp precision-narrowing casts in comparison
predicates instead of unwrapping them incorrectly.

Subject: [PATCH 306/878] fix: preserve no-filter SMJ matches across pending
 outer batches (#23049)

## Which issue does this PR close?

- Closes #23048

## Rationale for this change

When the no-filter bitwise sort-merge join path finds a matching key,
it advances the inner cursor past that key before marking all matching
outer rows. If the outer key group continues into the next outer batch
and polling that batch returns `Pending`, `poll_join` resumes from its
top-level state with the inner cursor already past the matched key.

On resume, the stream still retained the already-emitted outer batch.
That stale batch caused the pending boundary state to be applied to the
wrong batch and then discarded. When the actual next outer batch was
loaded later, rows continuing the matched key could compare as `Less`
than
the current inner key and be incorrectly treated as unmatched.

Fix this by clearing `outer_batch` after emitting the fully consumed
batch
and before polling for the next outer batch. This makes the resumed
top-level state load the actual next outer batch before applying
`resume_boundary`, matching the filtered code path.

## What changes are included in this PR?

* Bug fix for SMJ semi/anti-join behavior across outer batches
* Add unit test

## Are these changes tested?

Yes.

## Are there any user-facing changes?

No.

Subject: [PATCH 307/878] feat: logical plan protobuf representation for range
 repartitioning (#23030)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22787

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

The range repartitioning scheme for logical plans does not currently
have a protobuf representation.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

A protobuf representation of the `RangeRepartition` struct was added to
`datafusion.proto`, and the codegened Rust types were created. Added
logic for serializing and deserializing to and from the protobuf
representation, and a roundtrip test as well!

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes! Added a test in `roundtrip_logical_plan`

## Are there any user-facing changes?

No, adding internal protobuf serialization support for an existing
logical plan variant

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 308/878] Docs: Add `PartialSortExec` documentation (#23092)

@mhilton mentioned the other day that he was looking for PartialSortExec
but it wasn't well documented

So let's fix that!

## Summary
- expand PartialSortExec rustdoc with a concise explanation
- add an ASCII example showing partial sorting from (a, b) to (a, b, c)

cc @berkaysynnada and @akurmustafa perhaps you might have some time to

Subject: [PATCH 309/878] perf: optimize object store requests when reading CSV
 (#22962)

## Which issue does this PR close?

- Closes #21419

## Rationale for this change

The CSV scanner currently uses `calculate_range` which issues two extra
`get_opts` requests per byte range to find newline boundaries (one for
the start boundary, one for the end boundary), plus one GET for the
actual data. For a file split into 3 partitions, this results in 8 total
object store requests.

#20823 solved this same problem for the JSON scanner by introducing
`AlignedBoundaryStream`, which wraps the raw byte stream and lazily
aligns to newline boundaries as data is read, eliminating the extra
boundary-seeking requests entirely. This PR applies the same approach to
CSV.

## What changes are included in this PR?

Based on the approach from #20823:

Moved `AlignedBoundaryStream` from `datasource-json` to the shared
`datasource` crate so it can be reused by both JSON and CSV scanners.
Updated `CsvOpener` to use instead of `calculate_range`, and removed the
`calculate_range` & `find_first_newline` as they no longer had any
callers. Updated tests to reflect.

Public API changes include:
- Removal of the `RangeCalculation` enum
- Removal of the `calculate_change` function
- `boundary_stream` (containing `AlignedBoundaryStream`) moved from
`datafusion_datasource_json` to `datafusion_datasource`

## Are these changes tested?

Yes. The existing `AlignedBoundaryStream` unit tests (16 tests covering
boundary alignment edge cases) were moved along with the implementation
and continue to pass. The `query_csv_file_with_byte_range_partitions`
snapshot test in `object_store_access.rs` has been updated to verify the
new request pattern (4 requests instead of 8).


## Are there any user-facing changes?

No.

Subject: [PATCH 310/878] Fix DuckDB unparse for optimized join projections
 (#23002)

## Which issue does this PR close?

- Closes #22961.

## Rationale for this change

Optimized plans can introduce intermediate projection aliases from
common subexpression elimination and can also leave join conditions
referencing aliases from a flattened join input.

The SQL unparser was rebasing some unqualified optimizer aliases to a
table alias, producing invalid references such as
`"o"."__common_expr_1"`. It could also emit a derived projection around
a join input while the outer join condition still referenced aliases
inside that derived table, producing SQL that DuckDB rejects.

## What changes are included in this PR?

- Make `TableAliasRewriter` use `DFSchema` qualifier information instead
of only Arrow field names, with explicit control over whether
unqualified fields should be rebound to a table alias.
- Keep existing alias rebasing for table-scan filters and window-derived
inputs.
- Avoid wrapping qualified pass-through join projections when they are
used as the left input of another already projected join, so referenced
aliases remain in scope.
- Add a regression test for the optimized DuckDB unparse path from the
issue.

## Are these changes tested?

- `cargo fmt --all`
- `cargo test -p datafusion --test core_integration
optimized_duckdb_unparse_preserves_derived_table_scope`
- `cargo test -p datafusion-sql --test sql_integration`
- `cargo test -p datafusion-sql unparser::rewrite`
- `cargo clippy -p datafusion-sql --test sql_integration -- -D warnings`
- `cargo clippy -p datafusion --test core_integration -- -D warnings`

## Are there any user-facing changes?

No public API changes. This fixes SQL generated by the unparser for
optimized logical plans.

Subject: [PATCH 311/878] chore: gate `internal_datafusion_err` import behind
 the `proto` feature (#23075)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A — a trivial build-warning fix, no tracking issue.

## Rationale for this change

Building `datafusion-physical-expr` without the `proto` feature emits an
`unused import` warning:

```
warning: unused import: `internal_datafusion_err`
  --> datafusion/physical-expr/src/expressions/dynamic_filters/mod.rs:26
```

`internal_datafusion_err` is only referenced inside
`impl DynamicFilterPhysicalExpr { fn try_from_proto(..) }`, which is
itself gated
behind `#[cfg(feature = "proto")]`. The import was unconditional, so it
became
dead whenever `proto` is disabled.

## What changes are included in this PR?

Move the `internal_datafusion_err` import behind `#[cfg(feature =
"proto")]` so it
is compiled only when its sole use site is, matching the existing gate
on the
`try_from_proto` impl block.

## Are these changes tested?

No new tests — this is a compile-time-only change. It is exercised by
existing CI,
which builds the crate both with and without the `proto` feature; the
warning
(promoted to an error under `-D warnings`) no longer fires.

## Are there any user-facing changes?

No.

Subject: [PATCH 312/878] Perf: avoid redundant comparison in
 SortPreservingMerge round-robin tie-breaker; optimize inner loop (#23107)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes: #23108

## Rationale for this change

`SortPreservingMergeStream` (the loser-tree k-way merge behind
`SortPreservingMergeExec`, and `SortExec`'s spill/streaming merge) uses
a round-robin tie-breaker — enabled by default — applied at the root
comparison.

Two small inefficiencies on the hot `update_loser_tree` path:

1. At the root it compared the two finalists with `==` and then, when
not equal, again with `>` — up to **two** comparisons per output row
where the non-tie-breaker path does one. For byte-wise row comparisons
(multi-column keys) and string keys the extra comparison per row is
measurable.
2. The round-robin handling only applies at the root (`cmp_node == 1`),
yet the per-node loop tested `cmp_node == 1` (and carried the
tie-breaker branch) on every node.

On sort_tpch it shows some nice gains:
```
│ Q4    │  213.82 / 216.41 ±2.86 / 221.41 ms │   196.81 / 200.38 ±3.91 / 206.99 ms │ +1.08x faster │
│ Q5    │  300.12 / 300.95 ±0.45 / 301.43 ms │   280.25 / 281.01 ±1.13 / 283.25 ms │ +1.07x faster │
│ Q6    │  313.95 / 318.37 ±7.24 / 332.81 ms │   293.26 / 294.82 ±1.24 / 296.98 ms │ +1.08x faster │
```

## What changes are included in this PR?

- Collapse the root `==` + `>` into a single `Ord::cmp` and match on the
`Ordering`.
- Lift the root comparison out of the per-node loop, leaving a tight
`is_gt` inner loop (`while cmp_node > 1`) that no longer checks
`cmp_node == 1` per node.


## Are these changes tested?

Covered by the existing tests in `sorts/merge.rs` and
`sorts/sort_preserving_merge.rs` (including
`test_round_robin_tie_breaker_success` /
`test_round_robin_tie_breaker_fail` and the merge ordering tests).
Behavior-preserving, so no new tests are added.

## Are there any user-facing changes?

No.

Subject: [PATCH 314/878] Group scan time expression rewrite functionality for
 UDFs in new module in `datafusion-physical-expr-adapter` (#23125)

## Which issue does this PR close?

- Closes #.

## Rationale for this change

Instead of continuously adding more and more UDF-specific rewrite
utilities to `datafusion/physical-expr-adapter/src/schema_rewriter.rs`,
move all of them to a new `rewrite` module.

This issue was raised in recent PRs that added `input_file_name()` and
`file_row_index()`.

## What changes are included in this PR?

1. Introduce a new `rewrite` module in
`datafusion-physical-expr-adapter`, and move some functionality to it.

## Are these changes tested?

Existing testing suites.

## Are there any user-facing changes?

I don't think any of this code was released.

Subject: [PATCH 315/878] Move Parquet `input_file_name()` tests to
 `input_file_name.slt` (#23123)

## Which issue does this PR close?

- Closes #.

## Rationale for this change

This was part of #22978 which I had locally and apparently didn't push

## What changes are included in this PR?

Move parquet-only tests that only test `input_file_name()` from
`parquet_metadata_functions.slt` (which tests how the metadata functions
interact) to the canonical test file for the UDF.

## Are these changes tested?

They are tests. Verified locally.

## Are there any user-facing changes?

No

Subject: [PATCH 318/878] [physical-plan]: remove deprecated UnionExec::new
 (#23100)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- part of #23080

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`UnionExec::new` is deprecated in 44.0.0, and replaced
`UnionExec::try_new`

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
Removed the deprecated `UnionExec::new` constructor
## Are these changes tested?
verified by running local tests for `datafusion-physical-plan` package

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
Yes. This removes a public Rust API `UnionExec::new` that was deprecated
in 44.0.0. Downstream users should migrate to `UnionExec::try_new`.

This is an API change and should be labeled `api change`.

Subject: [PATCH 319/878] [sql]: remove deprecated TableReference re-exports
 (#23102)

## Which issue does this PR close?

- part of #23080

## Rationale for this change

`ResolvedTableReference` and `TableReference` re-exports were deprecated
in 46.0.0 in `datafusion-sql` and should be imported from
`datafusion_common` (or `datafusion::common`) instead.

## What changes are included in this PR?

- Removed deprecated `ResolvedTableReference` and `TableReference`
re-exports from `datafusion-sql` (`lib.rs`).
- Updated internal downstream imports in `datafusion-sql`,
`datafusion-core`, and `datafusion-substrait` to use correct paths.

## Are these changes tested?

Verified by running local compilation and tests.

## Are there any user-facing changes?

Yes. This removes deprecated public Rust API re-exports
`ResolvedTableReference` and `TableReference` from `datafusion-sql`.
Downstream users should migrate to importing them from
`datafusion_common` (or `datafusion::common`).

This is an API change and should be labeled `api change`.

## Summary

Removes the free function `datafusion_datasource::write::create_writer`,
which was deprecated in 48.0.0 with the suggestion to use
`ObjectWriterBuilder::new(...)` instead. Per the [API health deprecation
guidelines](https://datafusion.apache.org/contributor-guide/api-health.html#deprecation-guidelines),
APIs deprecated in 48.0.0 or earlier are now eligible for removal.

A grep across the workspace confirms `create_writer` has **zero
callers** anywhere in the repo (the other matches are differently-named
methods `create_writer_physical_plan` and `create_writer_props`, which
we are not touching) and is not re-exported from
`datafusion_datasource::lib`. This is the smallest possible pure-removal
cleanup — 16 lines deleted from a single file.

Part of  #23080 (partial — one of the listed eligible items).

## Test plan

```
git diff upstream/main..chore/remove-deprecated-create-writer
 datafusion/datasource/src/write/mod.rs | 16 ----------------
 1 file changed, 16 deletions(-)
```

Since all callers are gone, no test updates are needed; the standard CI
matrix (`./dev/rust_lint.sh`, `cargo check -p datafusion-datasource`,
downstream consumer builds) will catch any indirect breakage.

## AI assistance

Used an AI coding assistant to identify and minimally remove the unused
deprecated function. I read the file end-to-end before and after the
diff, verified zero callers via a workspace grep, and the change is a
16-line pure deletion.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add declared `output_partitioning` to file scan and listing table
configuration.
- Preserve declared partition counts during listing-table file grouping.
- Serialize scan `output_partitioning` through physical plan proto.
- Refactor `range_partitioning.slt` to use a CSV `ListingTable` instead
of a custom test-only `TableProvider` / `DataSource`.

Contract:
- Declared partitioning expressions are written against the full table
schema before scan projection. For example, `Range([range_key@0], [(10),
(20)], 3)` remains valid if the scan projects `range_key` and falls back
to `UnknownPartitioning(3)` if `range_key` is not projected.
- Listing tables create one file group per declared output partition
(which can exceed `target_partitions`). It is up to the user to plan
their partitioning. For example, a 4-partition range declaration creates
four scan file groups, adding empty trailing groups when fewer files are
present.
- File group index is part of the contract: file group `i` must contain
rows for declared output partition `i`. DataFusion does not validate row
placement, matching other user-declared properties such as sortedness.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

Yes. This adds public API for declaring file/listing scan output
partitioning. No breaking API changes.

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 324/878] chore(parquet): remove deprecated schema-coercion
 helpers (Closes #23080 - partial) (#23132)

Removes coerce_file_schema_to_view_type and
coerce_file_schema_to_string_type (both deprecated since 47.0.0 with
replacement apply_file_schema_type_coercions). Zero callers in the
workspace; only the function definitions and re-export entries in mod.rs
/ file_format.rs remain. Drops the now-unused #[expect(deprecated)]
attribute on the re-export lines. Pure 118-line deletion across 3 files.
Part of #23080 (partial - third in the housekeeping series after #23129
and #23131). AI assistance: used an AI coding assistant to identify and
remove unused symbols; verified via repo-wide grep that the deprecated
functions have no callers.

Subject: [PATCH 325/878] refactor(hash-aggr): Use `EmitTo` to output (#23055)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

Part of https://github.com/apache/datafusion/issues/22710

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Regarding the EPIC issue: I have drafted all the migrations locally, and
verified that after deleting the old implementation, UTs are passing.

We are now about 4 feature migration PRs away from completing the EPIC.
Before continuing with those migrations, this PR performs some cleanup
and refactoring.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
This PR can be read commit by commit:
- commit 1: use EmitTo for incremental outputting
- commit 2: split `hash_table.rs` into small files

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

+/// # Logical and Physical Model
+///
+/// Logically, this is a hash table that maps { group keys -> accumulator states }

+///
+/// Physically, the group keys and accumulators are backed by [`GroupValues`] and
+/// [`GroupsAccumulator`]. Both use columnar storage so aggregation can stay
+/// vectorized.
+///
+/// # Marker Type
+/// `AggrMode` selects the aggregate semantics.
+///
+/// e.g. `AggregateHashTable::<PartialMarker>::new(...)` creates an aggregate hash table
+/// for the partial hash aggregate stage, the input schema is raw rows and output
+/// schema is intermediate states.

+/// It is a zero-sized compile-time marker, so each stage keeps its update logic

Subject: [PATCH 326/878] refactor: centralize TopK heap boundary handling
 (#23091)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23073.

## Rationale for this change

TopK derives local heap-boundary data in multiple places. This refactor
names that boundary and keeps full sort-key bytes, scalar threshold
values, and prefix comparison tied to the same heap row.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

  - Add a private helper for the current local TopK heap boundary.
  - Use it when updating dynamic filter thresholds.
  - Use it for local prefix early-completion checks.
  - Remove the old duplicate scalar threshold extraction path.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 327/878] fix(proto): honor ExecutionPlan downcast_delegate
 during serialization (#23154)

## Which issue does this PR close?

N/A. This is a follow-up to #22559 and #21263, but there is no dedicated
issue for this specific bug.

## Rationale for this change

#21263 removed `ExecutionPlan::as_any()` now that `ExecutionPlan` has
`Any` as a supertrait. Most call sites were migrated from code like
this:

```rust
plan.as_any().downcast_ref::<SomeExec>()
```

to the new helper:

```rust
plan.downcast_ref::<SomeExec>()
```

That distinction matters after #22559. `ExecutionPlan::downcast_ref` is
now the public downcast operation for execution plans: it follows
`ExecutionPlan::downcast_delegate()` before falling back to raw `Any`.
This lets wrapper plans keep their own concrete type private while still
presenting the wrapped plan's normal public identity.

For example, tracing or instrumentation wrappers can implement
`downcast_delegate()` so callers that ask "is this a `FilterExec` /
`EmptyExec` / `ProjectionExec`?" get the same answer they would have
received without the wrapper. The wrapper remains visible only to code
that intentionally performs a raw concrete-type `Any` check.

This problem came up while trying to instrument distributed plans
through
[`datafusion-distributed`](https://github.com/datafusion-contrib/datafusion-distributed).
In that setting, physical plans may be wrapped for
tracing/instrumentation and then serialized for distributed execution.
The wrapper is meant to be transparent for normal plan inspection, but
serialization still needs to recognize the delegated built-in plan
underneath it.

The physical plan proto serializer still had one leftover mechanical
migration from the old `as_any()` world:

```rust
let plan = plan.as_ref() as &dyn Any;
```

That line bypasses `ExecutionPlan::downcast_ref` entirely. As a result,
a delegating wrapper around a built-in execution plan is not serialized
as the built-in plan. Instead, the serializer sees only the wrapper's
concrete type, fails all built-in `Exec` checks, and falls through to
the extension codec. With the default extension codec this produces an
unsupported-plan error, even though the wrapped plan itself is
serializable.

This is particularly relevant for transparent wrappers such as
[`InstrumentedExec`](https://github.com/datafusion-contrib/datafusion-tracing/blob/main/datafusion-tracing/src/instrumented_exec.rs)
in
[`datafusion-contrib/datafusion-tracing`](https://github.com/datafusion-contrib/datafusion-tracing),
which intentionally delegate public downcasts to the wrapped plan.

## What changes are included in this PR?

- Changes physical plan proto serialization to bind the plan as `&dyn
ExecutionPlan` instead of `&dyn Any`.
- Leaves the existing serializer downcast chain intact, so each
`plan.downcast_ref::<...>()` now dispatches through the `ExecutionPlan`
helper and therefore honors `downcast_delegate()`.
- Adds a regression test with a small wrapper execution plan that
delegates public downcasts to an inner `EmptyExec`.
- Audited other `as_ref() as &dyn Any` patterns. The remaining hits are
either non-`ExecutionPlan` traits, `PhysicalExpr` checks, UDF tests, or
the intentional raw `Any` fallback inside the `ExecutionPlan` helper
itself.

## Are these changes tested?

Yes.

```bash
cargo fmt --all
cargo fmt --all --check
cargo test -p datafusion-proto --test proto_integration serialize_uses_downcast_delegate
cargo clippy --all-targets --all-features -- -D warnings
```

## Are there any user-facing changes?

Yes, as a bug fix. Physical plan proto serialization now honors the
documented `ExecutionPlan::downcast_delegate()` behavior. Transparent
wrapper plans can serialize as their delegated built-in execution plan
when appropriate instead of requiring an extension codec for the wrapper
itself.

Subject: [PATCH 328/878] IN LIST: add UInt8 bitmap filter (#23011)

## Which issue does this PR close?

- Part of #19241.
- Stacked on #21927.
- Next in stack: #23012.
- Extracted from #19390.

## Rationale for this change

`IN LIST` evaluates expressions like `x IN (1, 3, 7)`. The list on the
right is fixed, so DataFusion can precompute a small lookup structure
once and then reuse it for every input row.

For `UInt8`, there are only 256 possible values: 0 through 255. That
means the lookup can be a tiny checklist with one bit per possible
value:

- If the list contains `3`, set bit `3`.
- If the list contains `7`, set bit `7`.
- To check whether an input value is present, read that one bit.

So instead of hashing each input value or comparing it against the list,
membership becomes one indexed bit test. The bitmap is only 32 bytes,
because 256 bits = 32 bytes.

This PR adds the first specialized primitive path in the stack as a
concrete `UInt8` filter. The `UInt16` version is added in #23012, and
the shared bitmap abstraction is introduced only after both concrete
implementations are visible in #23035.

## What changes are included in this PR?

- Adds `UInt8BitmapFilter`, a 32-byte bitmap built from the non-null
constants in the `IN` list.
- Routes `UInt8` constant-list filtering to that bitmap path.
- Keeps the same SQL null behavior as the generic path for both `IN` and
`NOT IN`.
- Moves shared dictionary-needle handling into `static_filter.rs`, so
specialized filters can reuse it consistently.
- Adds focused tests for `UInt8` null handling and dictionary-encoded
needles.

## Are these changes tested?

Yes.

- `cargo fmt --all`
- `cargo test -p datafusion-physical-expr bitmap_filter_u8 --lib`
- `cargo test -p datafusion-physical-expr in_list_int_types --lib`
- `cargo clippy -p datafusion-physical-expr --all-targets --all-features
-- -D warnings`

## Are there any user-facing changes?

No. This is an internal performance optimization only.

## Local benchmark snapshot

Benchmark command:

```bash
cargo bench -p datafusion-physical-expr --profile release-nonlto --bench in_list_strategy -- --save-baseline <name>
```

Method: compare adjacent saved baselines using raw Criterion sample
minima (`min(time / iters)`). Lower is better; changes within +/-5% are
treated as noise. These numbers were not rerun after splitting the
bitmap abstraction into #23035.

Compared baselines:
[#21927](https://github.com/apache/datafusion/pull/21927) ->
[#23011](https://github.com/apache/datafusion/pull/23011)

Relevant scope: UInt8 narrow-integer rows.

Summary: 5 relevant rows, 5 faster, 0 slower, 0 within +/-5%.

Subject: [PATCH 329/878] chore(physical-plan): remove deprecated RowIndex
 struct (Closes #23080 - partial) (#23143)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes part of  #23080

## Summary

Removes the deprecated `RowIndex` struct from
`datafusion-physical-plan`. The whole
`datafusion/physical-plan/src/sorts/index.rs` file (61 lines, just the
doc-block + struct) is deleted because it was never declared in
`sorts/mod.rs` and never re-exported via `pub use` — it was a dead file
already. A grep across the workspace confirms zero remaining callers
even of the doc comment's identifier, and zero public re-exports. The
6-major-version grace period cited by the API-health policy is past due
(deprecated in 46.0.0, we are now on 55.x).

## Test plan

- `git grep -nE '\bRowIndex\b'` returns no matches in source or docs
(false-positives filtered: `FileRowIndexFunc` is a separate,
undeprecated symbol).
- `sorts/mod.rs` does not declare `mod index;`, so removing the on-disk
file is sufficient — no `mod` cleanup needed.
- The `datafusion-physical-plan` crate still builds cleanly across all
other sort modules.

Subject: [PATCH 332/878] perf: avoid possibly expensive string formatting if
 no error is encountered (#23157)

## Which issue does this PR close?

We had a `LogicalPlan` extension for which it was expensive to print the
debugging information and which occurred multiple times in each query.
Because the old code always created a string with the debugging
information even in the success path, this overhead accumulated. I think
this was exaggerated by our huge debug info but I thought we could avoid
this.

Are there any existing benchmarks with respect to extension planning? At
least `sql_planner` and `sql_planner_extended` don't seem to have one on
first sight.

## Rationale for this change

Avoid printing debug info if it's not needed

## What changes are included in this PR?

- Swap an `&str` to a closure that computes the string on-demand.

## Are these changes tested?

Existing tests

## Are there any user-facing changes?

No

Subject: [PATCH 333/878] chore(catalog-listing): remove deprecated split_files
 free fn (Closes #23080) (#23152)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #23080 (partial)

## Summary

Removes `datafusion_catalog_listing::helpers::split_files`, deprecated
since 47.0.0 in favor of the `FileGroup::split_files` method on
`datafusion-catalog/datasource::file_groups::FileGroup`.

Verified workspace-wide:
- 0 non-test call sites for the deprecated free function (`grep -rn
"split_files" --include="*.rs"`)
- The 5 in-tree references in
`datafusion/catalog-listing/src/helpers.rs::tests::test_split_files` are
calls on `FileGroup` values (`files.clone().split_files(N)`), not the
deprecated free function — they exercise `FileGroup::split_files`
correctly.
- 3 other call sites in `datafusion/catalog-listing/src/table.rs` also
call the `FileGroup` method.
- `cargo check -p datafusion-catalog-listing` is clean (no warnings
after also dropping the now-unused `use std::mem;`).
- `cargo test -p datafusion-catalog-listing test_split_files` passes.

This is a 36-line pure deletion: 35 lines for the function body plus the
`use std::mem;` import. Replaces only — the public method
`FileGroup::split_files` already exists at
`datafusion/datasource/src/file_groups.rs:454` and is what callers use.

## Test plan

- `cargo check -p datafusion-catalog-listing` ✓ (clean)
- `cargo test -p datafusion-catalog-listing test_split_files` ✓ 1 passed
- `grep -rn "helpers::split_files\|use.*helpers::{.*split_files"
datafusion/` → 0 matches after this change

`(e of in-tree call sites verified before edit via workspace grep;
revisited after edit.)`

## AI assistance

This patch was drafted with the help of an AI coding assistant. The diff
was reviewed line by line before submission and the change was verified
independently (cargo check + a focused cargo test run).

 (Closes #23080 - partial) (#23142)

Fixes #23080

## Summary

Removes the deprecated `DFParser::new` and `DFParser::new_with_dialect`
constructors from `datafusion-sql`. Both were deprecated since 46.0.0 in
favor of the `DFParserBuilder` API, and a grep across the workspace
confirms zero remaining callers (the only references are to
`DFParser::parse_sql` and `DFParserBuilder::new`, which we keep). With
DataFusion now on 55.x, this clears the 6-major-version grace period for
trivial removal.

## Test plan

- `git grep -nE 'DFParser::new\b|DFParser::new_with_dialect\b'` returns
no results in source or docs.
- The `datafusion-sql` package's `DFParserBuilder` API surfaces
(`parse_sql`, `parse_sql_with_dialect`) are unchanged and provide
drop-in replacement ergonomics.

Subject: [PATCH 335/878] chore(common): remove deprecated DFSchema type-check
 method (Closes #23080 - partial) (#23144)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #23080

## Summary

Removes `DFSchema::check_arrow_schema_type_compatible`, deprecated since
47.0.0 ("This method is no longer used"). A grep across the workspace
confirms zero remaining callers and zero public re-exports — the method
is definition-only. The 6-major-version grace period cited by the
API-health policy is past due (we are now on 55.x).

## Test plan

- `git grep -nE 'check_arrow_schema_type_compatible'` returns no matches
in source or docs (only the removed definition site).
- `Schema` is still imported at the top of `dfschema.rs` because it
remains in use elsewhere in the file (e.g.,
`qualified_schema_from_field_names`, etc.).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #23080

## Summary

Removes `Signature::get_possible_types`, deprecated since 46.0.0 ("See
get_example_types instead"). A grep across the workspace confirms zero
remaining callers and zero public re-exports — the function is
definition-only. (The lone in-tree test, `test_get_possible_types`,
retained its name for stability but already exercises the new
`get_example_types` path.) The 6-major-version grace period cited by the
API-health policy is past due (we are now on 55.x).

## Test plan

- `git grep -nE '\bget_possible_types\b'` returns no matches in source
code (only the removed definition site). The 44.0.0 changelog entry is
historical and is left intact.
- `test_get_possible_types` continues to compile and pass since it never
called the deprecated function.

Subject: [PATCH 338/878] [sql]: remove old deprecated `DFParser::new` and
 `DFParser::new_with_dialect` (#23101)

## Which issue does this PR close?

- part of #23080

## Rationale for this change

`DFParser::new` and `DFParser::new_with_dialect` were deprecated in
46.0.0 and replaced by `DFParserBuilder`.

## What changes are included in this PR?

Removed the deprecated `DFParser::new` and `DFParser::new_with_dialect`
constructors from `datafusion-sql`.

## Are these changes tested?

Verified by running local tests for `datafusion-sql` package.

## Are there any user-facing changes?

Yes. This removes public Rust APIs `DFParser::new` and
`DFParser::new_with_dialect` that were deprecated in 46.0.0. Downstream
users should migrate to `DFParserBuilder`.

This is an API change and should be labeled `api change`.

Subject: [PATCH 340/878] chore(common): remove deprecated
 equivalent_names_and_types (Closes #23080) (#23153)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #23080 (partial)

## Summary

Removes the deprecated `DFSchema::equivalent_names_and_types` method
(deprecated since 47.0.0 in favor of `has_equivalent_names_and_types`).
5-line pure deletion. Verified workspace-wide: zero callers of the
deprecated method. The active method
`logically_equivalent_names_and_types` (different name, related logic)
is unaffected.

This is part of the deprecation-removal series against #23080.

## Test plan

- `cargo check -p datafusion-common` ✓ clean
- Workspace grep: 0 callers of `equivalent_names_and_types` outside the
deprecated method's own definition.

## AI assistance

This patch was drafted with the help of an AI coding assistant. Diff was
reviewed line by line before submission, and the change was verified
independently.

Subject: [PATCH 341/878] chore(expr-common): remove deprecated Signature
 get_possible_types (Closes #23080 - partial) (#23135)

Removes Signature::get_possible_types (deprecated since 46.0.0 with
replacement get_example_types). Pure 5-line deletion; the in-tree unit
test already calls get_example_types directly, so no test updates
needed. Closes #23080 (partial - fifth in housekeeping series after
#23129, #23131, #23132, #23134). AI assistance: used an AI coding
assistant; verified via repo-wide grep that the function is unused
outside tests.

Subject: [PATCH 343/878] [execution] Remove deprecated disk manager
 configuration API (#23139)

### Which issue does this PR close?
- Part of #23080

### Rationale for this change
`DiskManagerConfig` and `DiskManager::try_new` were deprecated in
version 48.0.0 in favor of the new `DiskManagerBuilder`. This PR remove
this deprecated methods and update Runtime env initialization logic

### What changes are included in this PR?
- Removed `RuntimeEnvBuilder::with_disk_manager` depercated method.
- Removed deprecated `DiskManagerConfig` enum and its associated
constructor methods.
- Removed deprecated `DiskManager::try_new` method.
- Refactored `RuntimeEnvBuilder` to store `Option<Arc<DiskManager>>`
instead of the old configuration enum.
- Update `RuntimeEnvBuilder::build` logic by using matching to handle
the existing manager, builder, or default initialization.

### Are these changes tested?
verifed by running local tests

### Are there any user-facing changes?
Yes. This removes the deprecated public Rust APIs
`RuntimeEnvBuilder::with_disk_manager`, `DiskManagerConfig` and
`DiskManager::try_new`. Downstream users who need to configure the disk
manager should migrate to using `DiskManager::builder`.

This is an API change and should be labeled as `api change`.

Subject: [PATCH 344/878] Fix projection functional dependency remapping
 (#23028)

## Which issue does this PR close?

- Closes #23027.

## Rationale for this change

Projection functional dependency propagation builds a mapping from
projected output expressions back to input field indices.

Before this change, projection expressions that are not direct input
fields, such as planner-generated computed expressions, were omitted
from that mapping. This shifted the projected positions of later
passthrough columns. If a primary key column appears after such a
computed expression, the projected schema can record the primary key
functional dependency against the wrong output index.

This showed up in the TPC-DS q39 planning path after primary key
constraints were added to the schemas: downstream aggregate planning was
reasoning from incorrect functional dependency metadata.

## What changes are included in this PR?

- Preserves one output slot per projection expression when remapping
functional dependencies.
- Uses a sentinel for computed / non-input projection expressions so
they do not match input functional dependencies, while still keeping
later passthrough column positions aligned.
- Applies the same positional behavior to aliases, wildcards, and direct
projection expressions.
- Adds a focused regression test for a leading computed projection
before a primary key column.

## Are these changes tested?

Yes.

```text
cargo fmt --all -- --check
cargo test -p datafusion-expr projection_with_leading_computed_column_preserves_pk
cargo test -p datafusion --test tpcds_planning q39
```

I also ran a debug SF10 TPC-DS all-query comparison for the fix path
separately; it completed with 0 failures. I am treating that as
diagnostic evidence, not a formal benchmark claim.

## Are there any user-facing changes?

No SQL syntax or public API changes.

Users may see corrected optimized plans and restored performance for
queries affected by projection functional dependency remapping.

Subject: [PATCH 346/878] [physical-plan]: remove deprecated
 spill_record_batch_by_size (#23029)

## Which issue does this PR close?

- part of https://github.com/apache/datafusion/issues/23080

## Rationale for this change

`datafusion_physical_plan::spill::spill_record_batch_by_size` was
deprecated in DataFusion `46.0.0` in favor of
`SpillManager::spill_record_batch_by_size`.

The [API health policy deprecation
guidelines](https://datafusion.apache.org/contributor-guide/api-health.html#deprecation-guidelines)
say deprecated methods remain for 6 major versions or 6 months,
whichever is longer. This API has exceeded that window, so this removes
the deprecated wrapper.

## What changes are included in this PR?

- Removes the deprecated
`datafusion_physical_plan::spill::spill_record_batch_by_size` function.

## Are these changes tested?
By CI
## Are there any user-facing changes?

Yes. This removes a public Rust API that was deprecated in DataFusion
`46.0.0`. Downstream users should migrate to
`datafusion_physical_plan::spill::SpillManager::spill_record_batch_by_size`.

This is an API change and should be labeled `api-change`.

Subject: [PATCH 347/878] fix: add assert to `HashJoinExec::swap_inputs`
 (#23078)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23077

## Rationale for this change

Dynamic filters are runtime state tied to the probe side. `swap_inputs`
changes the probe side, so preserving the old filter is unsafe and can
lead to wrong column references.


## What changes are included in this PR?


remove the `dynamic_filter` while swap inputs in `HashJoinExec`:

```rust
.with_dynamic_filter(None)
```

## Are these changes tested?

yes, add one test case

## Are there any user-facing changes?

no

Subject: [PATCH 348/878] Perf: cache primitive sort key in SortPreservingMerge
 to drop per-comparison bounds checks (#23162)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!-- No dedicated issue; this is a self-contained performance
improvement to the
sort-preserving merge hot path. Happy to file a tracking issue if
preferred. -->

- N/A (performance)

## Rationale for this change
Two inefficiencies in the hot path:

1. The single-column primitive/array cursor comparison was **not being
inlined**
(in profiles it appeared as a separate ~21% self-time symbol), and every
comparison
   bounds-checked the underlying `ScalarBuffer` twice.
2. `maybe_poll_stream` was called on **every** output row, even though
it is a
   no-op whenever the winner's cursor is still live (the common case).

## What changes are included in this PR?

- Inline the lightweight primitive/array cursor comparisons.
- Skip the per-row `maybe_poll_stream` call unless the winner's cursor
is
  actually exhausted and needs a fresh `RecordBatch`.
- Cache the current (and previous) value of a primitive cursor,
refreshed once
per `advance()` via a new `CursorValues::set_offset` hook (default
no-op;
  `ArrayValues` forwards to the inner cursor).

Subject: [PATCH 349/878] Migrate case conversion and substr_index to fallible
 string view builder APIs (#23074)

## Which issue does this PR close?

* Part of #22688

## Rationale for this change

This PR continues the migration to fallible string builder APIs for
string UDFs that previously relied on infallible `append_value` and
`append_placeholder` calls.

The non-ASCII case conversion paths in `string/common.rs` and the
generic implementations in `unicode/substrindex.rs` could panic when
string view metadata exceeds ByteView's `i32::MAX` limits. Converting
these call sites to use fallible builder APIs allows overflow conditions
to be propagated as `DataFusionError`s instead of causing panics.

This work is part of the broader effort in #22688 to eliminate
panic-based overflow handling in string builders.

## What changes are included in this PR?

* Migrated non-ASCII case conversion paths in `string/common.rs` to use:

  * `try_append_value`
  * `try_append_placeholder`
* Migrated `substr_index_general` and `map_strings` in
`unicode/substrindex.rs` to use:

  * `try_append_value`
  * `try_append_placeholder`
* Added fallible APIs to `StringViewArrayBuilder`:

  * `try_append_value`
  * `try_append_placeholder`
  * `try_ensure_long_capacity`
* Added overflow error generation for StringView-specific limits:

  * `string_view_overflow_error`
* Refactored StringView view construction to validate:

  * value length
  * buffer offsets
  * completed buffer count
* Preserved existing infallible APIs (`append_value`,
`append_placeholder`, `ensure_long_capacity`) as wrappers around the
fallible implementations, maintaining existing behavior for callers that
still use them.

## Are these changes tested?

Yes.

Added the following unit tests:

* `string_view_builder_try_append_success_path`
* `test_substr_index_all_nulls`

These tests verify:

* Successful operation of the new fallible StringView builder APIs.
* Correct null propagation behavior in `substr_index_general`.

Existing case conversion and `substr_index` tests continue to validate
the normal execution paths. No dedicated overflow-triggering tests were
added in this PR.

## Are there any user-facing changes?

No user-facing functionality changes are expected.

The primary behavioral change is that certain internal string-builder
overflow conditions can now be returned as `DataFusionError`s rather
than triggering panics, improving robustness in extreme cases.

Subject: [PATCH 350/878] fix: preserve empty projection when ser/de
 `HashJoinExec` and `NestedLoopJoinExec` (#23082)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23083

## Rationale for this change

`HashJoinExec` and `NestedLoopJoinExec` carry `projection:
Option<Vec<usize>>` but the proto field is `repeated uint32`. Proto3
can't tell `None` from `Some(vec![])`, and the decoder treats both as
`None`. `Some(vec![])` is reachable in real plans —
`try_embed_projection` produces it for `SELECT count(1) … JOIN …`
(#20191) — and after a round-trip the join silently switches from "emit
zero columns" to "emit all columns".

`FilterExec` has a workaround for the same limitation; these two execs
were missed.

## What changes are included in this PR?
Encode `Some(vec![])` as the single-element sentinel `[u32::MAX]` (never
a valid column index); recognise it on decode. Everything else goes
through unchanged.

```rust
// encode
projection: match exec.projection.as_ref() {
    None => Vec::new(),
    Some(v) if v.is_empty() => vec![u32::MAX],
    Some(v) => v.iter().map(|x| *x as u32).collect(),
},

// decode
let projection = match hashjoin.projection.as_slice() {
    [] => None,
    [u32::MAX] => Some(Vec::new()),
    indices => Some(indices.iter().map(|i| *i as usize).collect()),
};
```

Applied symmetrically to `HashJoinExec` and `NestedLoopJoinExec`.


## Are these changes tested?

yes, add roundtrip test case

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

Subject: [PATCH 351/878] fix: `array_compact` handle edge case with NULLs
 (#23192)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Rationale for this change

`array_compact(make_array(NULL, NULL, NULL))` returned `[NULL, NULL,
NULL]` instead of an empty array.

Root cause: `make_array(NULL, NULL, NULL)` has type `List(Null)`, whose
inner values are an Arrow `NullArray`. `NullArray::nulls()` returns
`None` (it has no validity buffer), so the default
`Array::is_null()` returns `false` for every index — even though every
element is logically null. The compaction loop saw "no nulls" and copied
all elements through unchanged.

  ## What changes are included in this PR?

- In `compact_list`, resolve the values' null mask once via
`values.logical_nulls()` and use that buffer for both the fast-path
check and the per-element null test. This correctly treats `NullArray`
(and any
  other type without a physical validity buffer) as all-null.
- Added a sqllogictest covering the untyped-NULL case: `select
array_compact(make_array(NULL, NULL, NULL))` → `[]`.

  ## Are these changes tested?

Yes — new test added in
`datafusion/sqllogictest/test_files/array/array_distinct.slt` alongside
the existing `array_compact` coverage. Existing `array_compact` tests
continue to pass.

  ## Are there any user-facing changes?

Yes — `array_compact` on a list of untyped NULLs now returns `[]`
(matching the typed-NULL behavior and user expectation) instead of
preserving the null elements. No API changes.

## Rationale for this change

`arrow::buffer::OffsetBufferBuilder` is a thin wrapper around `Vec<O>`
plus a `last_offset: usize` running counter; every `push_length(n)` does
a `checked_add` on `usize` and a `usize_as(O)` conversion. For
per-row loops with a known upfront row count, a direct `Vec<O>` that
stores the running offset via `offsets[row] + O::usize_as(len)` can save
measurable work in tight per-row loops — provided the offset push
  is a meaningful fraction of per-row cost.

I swapped the pattern in all eight `OffsetBufferBuilder` call sites in
the repo (`array_normalize`, `array_filter`, `remove`, `replace`,
`array_add`, `utils::general_array_zip_with`, `array_scale`,
`encoding::delegated_decode`), benchmarked the three sites that have
criterion benches, and found the win is **not** uniform.

  ## What changes are included in this PR?

Replace `OffsetBufferBuilder<O>` with `Vec<O>` (preinitialized with
`O::zero()` and finalized with `OffsetBuffer::new(v.into())`) **only**
in `datafusion/functions-nested/src/remove.rs`, where benches show
  clean wins with no regressions.

The other seven sites are left on `OffsetBufferBuilder` — benches showed
flat-to-regressing results, see below.

  ## Are these changes tested?

Existing unit tests, doctests, and sqllogictests (`array_remove*`) pass
unchanged. No new tests — refactor is functionally equivalent.

  ## Are there any user-facing changes?

  No.

  ## Benchmark results

The biggest win is `array_remove`

  ### `array_remove`

  | Bench | size 10 | size 100 | size 500 |
  |---|---:|---:|---:|
  | `int64` | −0.2% | −1.0% | **−50.0%** |
  | `n_int64` | −0.7% | +0.05% | **−23.1%** |
  | `all_int64` | +0.2% | −1.8% | **−15.1%** |
  | `strings` | +3.8% | +0.6% | **−4.6%** |
  | `boolean` | −0.01% | +1.1% | +0.3% |
  | `fixed_size_binary` | −0.06% | **−20.0%** | **−2.6%** |
  | `int64_nested` | flat | flat | flat |


For others its more like noise

See `HashJoinExec: ... build_mem_used=2.80 B`, it actually means 2.8
billion bytes, but it looks quite misleading. This PR fixes it:

```sh
+-------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------+
| plan_type         | plan                                                                                                                                                  |
+-------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------+
| Plan with Metrics | HashJoinExec: mode=Partitioned, join_type=Inner, on=[(v1@0, v1@0)], metrics=[output_bytes=1526.7 MB, build_mem_used=2.6 GB]
```

The reason is those metrics are tracking peak memory usage for a
operator in the query lifecycle, so it's using `Gauge` metrics type, but
how to choose display format become tricky (bytes or count?)

This PR adds a new `Metric` type, that wraps the existing `Gauge`, and
use it to represent 'gauge for memory bytes', this fixes the bytes
display issue.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
1. Introduce `MetricValue::PeakMemoryUsage` to address the above issue
2. Use this metric type for applicable metrics
3. Add slts for testing.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
4. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 354/878] IN LIST: add UInt16 bitmap filter (#23012)

## Which issue does this PR close?

- Part of #19241.
- Stacked on #23011.
- Next in stack: #23035.
- Extracted from #19390.

## Rationale for this change

#23011 uses a bitmap checklist for `UInt8`, where there are 256 possible
values. `UInt16` is the same idea with a larger value range: 0 through
65,535.

That is still small enough to represent directly. A `UInt16` bitmap
needs one bit for each possible value:

- 65,536 possible values
- 65,536 bits total
- 8 KB of memory

Then a lookup is still simple: use the input value as the bit position
and check whether that bit is set. For example, if the list contains
`42`, bit `42` is set, and every input row with value `42` can be
recognized with one bit test.

This PR keeps the scope narrow: it adds the unsigned 2-byte bitmap path
as a concrete `UInt16` filter. #23035 then unifies the `UInt8` and
`UInt16` implementations, and #23013 uses that shared shape for signed
same-width reinterpretation.

## What changes are included in this PR?

- Adds `UInt16BitmapFilter`, backed by a heap-allocated 65,536-bit
bitmap.
- Routes `UInt16` constant-list filtering to that bitmap path.
- Keeps the same `IN` / `NOT IN` null behavior as the generic path.
- Adds focused coverage for `UInt16` boundary values, nulls, and `NOT
IN`.

## Are these changes tested?

Yes.

- `cargo fmt --all`
- `cargo test -p datafusion-physical-expr bitmap_filter_u16 --lib`
- `cargo test -p datafusion-physical-expr in_list_int_types --lib`
- `cargo test -p datafusion-physical-expr
test_in_list_from_array_type_combinations --lib`
- `cargo test -p datafusion-physical-expr test_in_list_dictionary_types
--lib`
- `cargo clippy -p datafusion-physical-expr --all-targets --all-features
-- -D warnings`

## Are there any user-facing changes?

No. This is an internal performance optimization only.

<!-- codex-benchmark-start -->
## Benchmark note

No local `in_list_strategy` numbers are included for this PR because the
benchmark harness does not currently include a direct `UInt16` case. The
available `i16` rows measure the signed reinterpretation path added in
#23013 after the bitmap unification in #23035, not this PR's unsigned
`UInt16` bitmap filter.

Subject: [PATCH 356/878] Fix final hash aggregate output regression by
 materializing once (#23182)

## Which issue does this PR close?

- part of https://github.com/apache/datafusion/issues/22710
- short-term solution for #23178.
- closes https://github.com/apache/datafusion/issues/23178

## Rationale for this change

PR #23055 changed final hash aggregate output to emit groups
incrementally with
`EmitTo::First(batch_size)`. For terminal final aggregate output, this
can cause
the group value state to be repeatedly compacted while output batches
are being
produced. On TPC-DS q23 this showed up as a significant regression.

This PR implements the short-term approach discussed in #23178:
materialize the
final aggregate output once, then return slices of that materialized
`RecordBatch` according to `batch_size`.

This avoids changing the `GroupValues` API while preserving bounded
downstream
batch sizes.

## What changes are included in this PR?

- Adds an `OutputtingMaterialized` hash aggregate state.
- Adds `MaterializedOutput`, a small wrapper around a `RecordBatch` plus
output
  offset.
- Changes final hash aggregate output to:
  - emit all final groups once,
  - evaluate all final aggregate values once,
  - slice the materialized batch for subsequent output polling.
- Leaves partial aggregate output behavior unchanged.
- Adds focused tests for materialized output slicing and final hash
aggregate
  output state transitions.

## Performance
TPC-DS SF10 full 99 queries, 10 rounds:

- Total runtime ratio: `0.857051`
- Geomean ratio: `0.976652` (~2.4% faster)
- q23 ratio: `0.313770` (~218.7% faster), faster in `10/10` rounds

Regressions over 5% were observed in 10 queries. Most have small
absolute
deltas, but the largest slowdowns were:

- q67: `1.055907`, +170.996 ms
- q39: `1.060436`, +98.544 ms
- q9: `1.050135`, +37.858 ms
- q70: `1.061124`, +11.848 ms
- q35: `1.052392`, +9.386 ms
- q33: `1.063655`, +6.995 ms
- q98: `1.071688`, +6.515 ms
- q91: `1.109819`, +5.362 ms
- q15: `1.058356`, +5.072 ms
- q27: `1.057686`, +0.815 ms

Overall, this recovers the q23 regression strongly and improves
full-query
geomean, but q39 and q67 are worth calling out as residual per-query
slowdowns.

## Testing

- `cargo fmt --all -- --check`
- `cargo test -p datafusion-physical-plan materializ`
- `cargo test -p datafusion-physical-plan aggregates::`
- TPC-DS SF10 q23, 3 rounds
- TPC-DS SF10 full 99 queries, 10 rounds

Subject: [PATCH 357/878] Add regression coverage for quoted dotted column
 aliases (#23155)

## Which issue does this PR close?

Follow up to #22917, I overlooked these:
- Add SLT regression coverage for quoted dotted names / column-list
aliasing.
- remove redundant .clone() after columns() since it already returns
Vec<Column>.


## What changes are included in this PR?

This PR adds SLT regression coverage for quoted dotted column names used
with table column-list aliasing, including qualified and unqualified
references.

It also removes a redundant `.clone()` call after
`plan.schema().columns()`.

## Are these changes tested?

Yes. Tests are added in:

`datafusion/sqllogictest/test_files/alias.slt`

## Are there any user-facing changes?

No user-facing changes.

## LLM-generated code disclosure

This PR includes LLM-generated code and comments. All LLM-generated
content has been manually reviewed.

Subject: [PATCH 358/878] perf: coalesce single-column sort runs to cut merge
 fan-in (#23202)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Closes

## Rationale for this change

When a sort exceeds `sort_in_place_threshold_bytes`, `ExternalSorter`
sorts each buffered batch individually and merges them all. With many
small input batches this gives a very high merge fan-in
(hundreds/thousands of one-batch runs). For single-column sorts the
per-stream cursor/merge overhead dominates, making this much slower than
sorting a few larger runs.

## What changes are included in this PR?

For **single-column** sorts, coalesce the buffered batches into a small
number of larger runs (each bounded by `sort_in_place_threshold_bytes`,
the same limit the in-place concat path already uses) before sorting and
merging.

### Why only single-column?

The optimal strategy flips with column count, so coalescing is gated to
`expr.len() == 1`:

- **Single column** is *fan-in bound*: the merge uses typed
`FieldCursorStream` cursors (native primitive/string compares), so the
per-key compare is cheap and the per-stream cursor/merge overhead
dominates. Collapsing hundreds/thousands of one-batch runs into a few
larger runs is a clear win.
- **Multi-column** is *compare bound*: the merge already uses the Arrow
row format (`RowCursorStream`). Streaming-merging many small row-format
runs beats running a few large lexicographic-comparator sorts, so
coalescing there *regresses* (all-string/dict tuples ~0.45×). Left as
one run per batch.

Note we don't switch the single-column in-memory path to a single global
row-format sort either: encoding every row to comparable bytes up front
is pure overhead vs. `lexsort_to_indices` (which only sorts `u32`
indices over the native arrays). Row-format sort only wins for
single-column high-cardinality `StringView` (~25%) and loses for
primitives.

Microbenchmarks (`benches/sort.rs`, single-column): i64/f64 ~2×,
utf8/utf8view ~1.6–1.9×, dictionary up to 2.4×; **geomean ~1.77×** at
100k & 1M rows. Multi-column unchanged.

## Are these changes tested?

Existing + a new `test_in_mem_sort_coalesced_runs` verifying the
coalesced multi-run merge produces a correct total order (incl. NULLs).

## Are there any user-facing changes?

No (internal performance change only).

Subject: [PATCH 359/878] feat(functions-aggregate): support sum(interval)
 (#23177)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

  - Part of #23085.

  ## Rationale for this change

PostgreSQL supports `sum()` over `interval` values via component-wise
addition; DataFusion currently
  only supports `sum()` on `Duration`, so a query like

  ```sql
  SELECT sum(value) FROM (VALUES
(interval '1 second'), (interval '1 year'), (interval '1 month'))
t(value);
  ```

errors with No function matches the given name and argument types
'sum(Interval(MonthDayNano))'. The
most useful real-world case is summing time-series gaps / durations
expressed as intervals, which the
  issue filer calls out.

  ## What changes are included in this PR?

  ## Are these changes tested?

  Yes.

  ## Are there any user-facing changes?

Yes — SUM(<Interval(YearMonth | DayTime | MonthDayNano)>) and
SUM(DISTINCT <interval>) are now valid;
previously they errored at planning time with No function matches. No
change to existing behavior on
  any other type. No public API changes.

A note for reviewers: the rendered output for (months=13, days=0,
nanos=1e9) is 13 mons 1.000000000
secs rather than PostgreSQL's 1 years 1 mons 0 days 0 hours 0 mins 1.0
secs. The stored value is
identical; the difference is a display-formatter choice in DataFusion
(it doesn't normalize 13 mons to
  1 year 1 month). Keeping that out of scope here.

Subject: [PATCH 360/878] feat: add array_avg scalar function (#23168)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

Adds `array_avg`, the last function from the split-PR pipeline tracked
in #21536.

Computes the arithmetic mean (sum divided by count) of the elements of a
numeric array, returned as `Float64`. Templated from the merged
`array_sum` (#22542) with the same SQL aggregate NULL conventions;
sibling of `array_sum`, `array_product`, `array_subtract`, `array_add`,
`array_scale`, and `array_normalize`.

## Semantics

**NULL semantics — SQL aggregate convention (deliberate divergence from
binary-op siblings):**
- NULL row → NULL row out
- NULL elements are **skipped** from BOTH the sum and the count,
matching PostgreSQL `AVG`, DuckDB `list_avg`, Spark `aggregate`. So
`array_avg([1, NULL, 3]) = (1+3) / 2 = 2`, not `(1+3) / 3`.
- All-NULL row → NULL out (matches `AVG(...)` over an all-NULL column)
- **Empty array → NULL** (matches sibling `array_sum` #22542 and
`array_product` #22703, PostgreSQL, DuckDB `list_avg`, SQL Standard
AVG-of-empty-set)

**Type coercion:**
- Inner numeric types (`Float32`, `Int*`, `UInt*`) coerced to `Float64`.
Integer-arg literals are coerced too.
- Return type is always `Float64` (since avg of integers can be
non-integer).

**List shapes supported:** `List`, `LargeList`, `FixedSizeList`.

**Alias:** `list_avg` (matches the `list_sum` / `list_product` pattern).

## Test coverage

SLT (`array_avg.slt`) covers:
- Happy paths (basic, single element, negative values, cancelling
positive/negative, non-integer mean `[1,2] → 1.5`)
- All NULL shapes: bare `NULL` row, NULL elements skipped, single
non-NULL among NULLs, all-NULL array
- Empty array → NULL
- All 3 list shapes (`List`, `LargeList`, `FixedSizeList`)
- Float32, Int64 inner types, integer literals, integer mean that is
non-integer
- Multi-row mix
- Error paths (non-list input, zero args, two args)
- Return type assertion (`Float64`)
- `list_avg` alias

## Closes

The last open slot in #21536 — completes the 8-function split-PR
pipeline from the originally-too-big PRs #21371 / #21376.

Subject: [PATCH 361/878] fix(spark): return error from ELT coerce_types when
 fewer than 2 args (#23164)

## Which issue does this PR close?

- Closes N/A

## Rationale for this change

`SparkElt::coerce_types` validates that ELT receives at least 2
arguments (index + value1), but the error was never returned: it was
built with `plan_datafusion_err!(...)` as an expression statement whose
value was discarded. Since `DataFusionError` is not `#[must_use]`, the
compiler didn't warn, so the function fell through and continued with
fewer arguments than required instead of failing with a clear plan-time
error.

## What changes are included in this PR?

In datafusion/spark/src/function/string/elt.rs, the argument-count check
is wrapped in return Err(plan_datafusion_err!(...)) so the validation
actually short-circuits when fewer than 2 arguments are provided.

## Are these changes tested?

This change restores an error path that was previously dropped silently.
ELT's normal behavior is already covered by the existing tests in
elt.rs. The invalid-arity branch had no coverage because it was never
actually exercised.

## Are there any user-facing changes?

ELT now returns a plan-time error when invoked with fewer than 2
arguments, instead of silently continuing. No public API changes.

Subject: [PATCH 362/878] feat: Support Decimal type in `approx_distinct`
 (#23190)

## Which issue does this PR close?

- Relates to https://github.com/apache/datafusion/issues/22989 but does
not close it. More types are coming.

## Rationale for this change

- Support the SQL `Decimal` type for `approx_distinct`

- The Arrow types `Decimal32`, `Decimal64`, `Decimal128` and
`Decimal256` can be directly supported for `NumericHLLAccumulator` and
`HllGroupsAccumulator`


## What changes are included in this PR?

- Enable `NumericHLLAccumulator` and `HllGroupsAccumulator` to support
`Decimal32`, `Decimal64`, `Decimal128` and `Decimal256`.
- Tests for the non-grouped and grouped path as part of
`approx_distinct.rst` and `aggregate.slt` for `Decimal128` and
`Decimal256`
- Benchmarks

## Are these changes tested?

Yes

## Are there any user-facing changes?

Yes, `approx_distinct` supports now `Decimal` but no breaking changes.

Subject: [PATCH 364/878] =?UTF-8?q?perf:=20share=20encoder/reservation=20a?=
 =?UTF-8?q?cross=20PartitionedTopKExec=20partition=20=E2=80=A6=20(#23096)?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Follow-up to #21479 (`PartitionedTopKExec` for `ROW_NUMBER ... PARTITION
BY ... LIMIT N`) toward closing #6899.

  ## Rationale for this change

`PartitionedTopKExec` today maintains a `HashMap<OwnedRow, TopK>` — one
full `TopK` per distinct partition key. Each `TopK` carries its own
`RowConverter`, `MemoryReservation` registered with the runtime pool,
`TopKMetrics`, and scratch `Rows` buffer. With high partition
cardinality every partition seen for the first time pays:

- `RowConverter::new` (parses `SortField` list, allocates per-encoder
state)
  - `MemoryConsumer::register` with the pool (involves a global lock)
  - per-counter `TopKMetrics` setup
  - scratch `Rows::empty_rows` allocation

For the h2o window-TopN sweep on a 10M-row CSV (`id3 % N` partition
cardinality), this shows up as a regression at ≥10K partitions —
`PartitionedTopKExec` is slower than the unpartitioned `SortExec`
baseline that it's meant to replace.

  ## What changes are included in this PR?

Adds a `PartitionedTopK` sibling type to `topk/mod.rs` that holds the
shared encoder/reservation/metrics state once at the operator level and
a `HashMap<OwnedRow, TopKHeap>` of cheap per-partition heap state.
`PartitionedTopKExec` switches from `HashMap<OwnedRow, TopK>` to one
`PartitionedTopK`.

  ### Bench results

  #### Today's default (main, flag-off) vs this PR (flag-on)

  | Partitions | main flag-off | this PR flag-on | Delta |
  |-----------:|--------------:|----------------:|-------|
  | 100        | 282 ms        | 105 ms          | **2.7x faster** |
  | 1,000      | 247 ms        | 110 ms          | **2.2x faster** |
  | 10,000     | 250 ms        | 137 ms          | **1.8x faster** |
  | 100,000    | 222 ms        | 320 ms          | 1.4x slower |

h2o `id3 % N` sweep, 10M-row CSV, 3 iterations per query, release build,
`enable_window_topn=true` on both sides:

  | Partitions | `main` | this PR | Speedup |
  |-----------:|-------:|--------:|--------:|
  |        100 | 110 ms | 105 ms  | ~1.0× |
  |      1,000 | 117 ms | 110 ms  | ~1.0× |
  |     10,000 | 640 ms | 137 ms  | **4.7×** |
  |    100,000 | 4,327 ms | 320 ms | **13.5×** |

10K is the inflection point: on `main` it's a regression vs the sort
baseline (640 ms vs 234 ms); after this PR it's a win (137 ms vs 234 ms
— 1.7× faster than sort). 100K nearly catches up to the sort baseline
(320 ms vs 238 ms).

`enable_window_topn` default stays `false` per the #21479 discussion —
100K+ remains slower than sort on average, so this PR doesn't motivate
flipping the default. It's the prerequisite for further optimizations
that would attack the residual 100K+ cliff.

  ## Are these changes tested?

  Yes

 ## Are there any user-facing changes?

  No public API changes.

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23159

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Join unparsing handles the left and right inputs inline in
`select_to_sql_recursively` (`datafusion/sql/src/unparser/plan.rs`).
Both sides
repeated the same table-scan filter extraction
(`try_transform_to_simple_table_scan_with_filters`: extend the collected
filters, then return the simplified or original plan), while the
passthrough-`Projection(Join)` handling intentionally diverges per side
(the
left input can be unwrapped; the right input may need a nested-join
relation so
SQL preserves the required join grouping).

Centralizing only the duplicated common setup — and keeping the
side-specific
behavior explicit — makes the two paths easier to read and keeps the
alias-scope invariant in one obvious place. #23159 tracks this.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Extract the duplicated filter-extraction dispatch into a small helper
`extract_join_input_table_scan_filters(plan, &mut table_scan_filters)`,
and
  call it from both the left and right join-input paths.
- Keep the side-specific passthrough-projection handling inline and
explicit
  (left: `unwrap_qualified_passthrough_join_projection`; right:
  `qualified_passthrough_join_projection_to_nested_relation`).
- Tests: factor the shared three-table setup into a
  `nested_passthrough_join_tables()` helper, and add

`test_unparse_projected_join_unwraps_left_nested_passthrough_projection`
to
mirror the existing right-input test (this also fills a left-side
coverage
  gap).

This is a pure refactor with no behavior change.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Covered by existing tests plus the new left-input test, all passing:

- `cargo test -p datafusion-sql --test sql_integration`
  (includes both `..._left_..._passthrough_projection` and
  `..._right_..._passthrough_projection`)
- `cargo clippy -p datafusion-sql --tests -- -D warnings`
- `cargo fmt --all`

Existing inline snapshots are unchanged (no behavior change); the new
test locks
in the left-input behavior the refactor touches.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
No. This is an internal refactor of the SQL unparser; the generated SQL
is
unchanged and there are no public API changes.

Subject: [PATCH 366/878] chore(datasource): remove deprecated add_row_stats
 (Closes #23080 - partial) (#23134)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removes datafusion_datasource::add_row_stats (deprecated since 47.0.0
with replacement Statistics::add). Zero callers — the only references
are the deprecated function definition and a single pub use re-export
(carrying an explicit 'Remove when add_row_stats is remove' comment,
indicating this was already acknowledged as future work). Pure 11-line
deletion across 2 files. Closes #23080 (partial - fourth in housekeeping
series after #23129, #23131, #23132). AI assistance: used an AI coding
assistant; verified via repo-wide grep that the function has no callers.

Subject: [PATCH 367/878] refactor: factor distinct-from unparsing into a
 shared helper (#23163)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23158

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

The `IsDistinctFrom` and `IsNotDistinctFrom` arms of `expr_to_sql_inner`
each carried a near-identical `match self.dialect.distinct_from_style()`
block, dispatching over `DistinctFromStyle::{FullText, Spaceship}`. The
two
copies differed only in whether the comparison is "distinct" or
"not distinct", so the dialect-handling logic was duplicated. #23158
tracks
factoring this out.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add a private helper `distinct_from_to_sql(&self, left, right,
is_distinct)`
  that performs the `DistinctFromStyle` dispatch in a single place.
- Call it from both arms: `IsDistinctFrom` with `is_distinct = true` and
  `IsNotDistinctFrom` with `is_distinct = false`.

This is a pure refactor with no behavior change.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Covered by existing tests, since there is no behavior change:

- `cargo test -p datafusion-sql --lib unparser` (incl.
`test_is_distinct_from`)
- `cargo test -p datafusion-sql --test sql_integration`
- `cargo clippy -p datafusion-sql -- -D warnings`
- `cargo fmt --all`

I also checked by hand that all four combinations
(`FullText`/`Spaceship` × distinct/not-distinct) produce the same
`ast::Expr`
as before.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
No. The helper is private and the generated SQL is unchanged for every
dialect. No public API changes.

Subject: [PATCH 368/878] fix: Preserve integer values in round() for large
 Int64 and UInt64 inputs (#22697)

## Which issue does this PR close?

- Closes #22696 .

## Rationale for this change

`round()` should not change integer values when the scale is
non-negative, since no fractional digits need to be rounded.

Currently, core `round()` coerces large `Int64` values through
`Float64`, causing precision loss:

```sql
SELECT round(arrow_cast(9007199254740993, 'Int64'));
````

Before/Current Buggy Output:

```text
9007199254740992.0
```

Expected:

```text
9007199254740993
```

The Spark-compatible `round()` also fails for `UInt64` values above
`i64::MAX` even when the scale is non-negative:

```sql
SELECT round(arrow_cast(18446744073709551615, 'UInt64'));
```

Before/Current Buggy Output:

```text
round: UInt64 value 18446744073709551615 exceeds i64::MAX and cannot be rounded
```

## What changes are included in this PR?

* Preserved integer inputs in core `round()` for non-negative scales
instead of routing them through `Float64`.
* Preserved `UInt64` values in Spark-compatible `round()` when the scale
is non-negative, avoiding unnecessary `UInt64 -> i64` conversion.
* Added SQLLogicTest coverage for:

  * `Int64` values above `2^53` in core `round()`.
  * `UInt64::MAX` in Spark-compatible `round()`.
  * Both one-argument and two-argument forms.

## Are these changes tested?

Yes.

```bash
cargo fmt --all
git diff --check
cargo test -p datafusion-sqllogictest --test sqllogictests -- spark/math/round.slt
cargo test -p datafusion-functions round
cargo test -p datafusion-spark round
```

I also verified the core regression queries manually:

```sql
SELECT arrow_typeof(round(arrow_cast(9007199254740993, 'Int64'))),
       round(arrow_cast(9007199254740993, 'Int64'));
```

Result:

```text
Int64 9007199254740993
```

```sql
SELECT arrow_typeof(round(arrow_cast(9007199254740993, 'Int64'), 2)),
       round(arrow_cast(9007199254740993, 'Int64'), 2);
```

Result:

```text
Int64 9007199254740993
```

## Are there any user-facing changes?

No.

Subject: [PATCH 369/878] IN LIST: unify bitmap filter implementations (#23035)

## Which issue does this PR close?

- Part of #19241.
- Stacked on #23012.
- Next in stack: #23013.
- Extracted from #19390.

## Rationale for this change

#23011 and #23012 intentionally introduce the `UInt8` and `UInt16`
bitmap filters as concrete implementations. With both widths visible,
the shared shape is now clear: each filter builds a fixed-size bitmap
from non-null `IN` list values and probes it with the input value's
integer bit pattern.

This PR factors that duplicated bitmap machinery into one
`BitmapFilter<T>`, where `T` is the Arrow primitive type (`UInt8Type` or
`UInt16Type`). Arrow remains the source of truth for the native Rust
value through `T::Native`; the only extra type-specific piece is the
bitmap storage size, supplied by a small private `BitmapFilterType`
trait implemented for those two Arrow types.

This does not add a new lookup strategy or change which data types use
bitmap filters. The next PR uses this shared shape to let same-width
signed integers reuse the unsigned bitmap storage.

## What changes are included in this PR?

- Adds `BitmapStorage` for fixed-size bitmap backing stores.
- Adds `BitmapFilterType`, a private extension trait that supplies the
bitmap storage size for `UInt8Type` and `UInt16Type`.
- Replaces the concrete `UInt8BitmapFilter` and `UInt16BitmapFilter`
implementations with `BitmapFilter<T>`.
- Uses Arrow's `T::Native` directly when setting and checking bit
positions.
- Keeps `UInt8` and `UInt16` routing behavior unchanged.

## Are these changes tested?

Yes.

- `cargo fmt --all`
- `cargo test -p datafusion-physical-expr bitmap_filter_ --lib`
- `cargo test -p datafusion-physical-expr in_list_int_types --lib`
- `cargo test -p datafusion-physical-expr
test_in_list_from_array_type_combinations --lib`
- `cargo test -p datafusion-physical-expr test_in_list_dictionary_types
--lib`
- `cargo clippy -p datafusion-physical-expr --all-targets --all-features
-- -D warnings`

## Are there any user-facing changes?

No. This is an internal refactor only.

<!-- codex-benchmark-start -->
## Benchmark note

No local benchmark numbers are included for this PR because it is
intended to be a behavior-preserving refactor of the bitmap filter
implementation. Benchmarks were not rerun for this stack split.

Subject: [PATCH 370/878] feat: introduce pluggable SpillFile trait and
 TempFileFactory for custom spill backends (#21882)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #21215, depends on #22230

## Rationale for this change

DataFusion’s spill infrastructure is tightly coupled to OS-level files,
with no extension points for alternative storage backends. `DiskManager`
cannot be customized for file creation, and `IPCStreamWriter` depends on
OS file paths.
This prevents integration in environments where temporary storage must
be managed by the host system. For example, Postgres extensions (e.g.,
ParadeDB) require spill files to go through `BufFile` APIs to respect
`temp_tablespaces`, enforce `temp_file_limit`, and integrate with
transaction-scoped cleanup. Since `BufFile` has no OS-visible path, it
cannot work with the current design.
A secondary motivation raised by @alamb is supporting object storage
backends (S3, GCS) for spilling, which require async IO and cannot use
`std::io::Write` or `std::io::Read`.

## What changes are included in this PR?

- Introduced `SpillFile`, `SpillWriter`, and `TempFileFactory` traits to
abstract spill file handling
- Added `DiskManagerMode::Custom` to allow pluggable backends
- Updated `DiskManager` to return `Arc<dyn SpillFile>` instead of
OS-bound types
- Refactored write path using `SpillWriteAdapter` to bridge sync Arrow
writers with backend-agnostic writers
- Refactored read path to use async streaming (`Stream<Item =
Result<Bytes>>`) instead of blocking state machines
- Updated spill-related components to operate on `Arc<dyn SpillFile>`
- Migrated the Sort-Merge Join (SMJ) operator to use the async spill
abstraction

## Are these changes tested?

Yes. Existing spill tests cover the full read/write flow.

- Fixed `test_disk_usage_decreases_as_files_consumed` by correcting a
pre-existing off-by-one assumption in file rotation
- Fixed `test_preserve_order_with_spilling` by just asserting spilling
occurs (`spill_count>0`) and output batches are sorted

## Are there any user-facing changes?

Yes this introduces API changes:

- Spill-related APIs now use `Arc<dyn SpillFile>` instead of
`RefCountedTempFile`
- New public traits: `SpillFile`, `SpillWriter`, `TempFileFactory`
- Added `DiskManagerMode::Custom` for custom backends

Custom spill backends can now be implemented and plugged in via
`DiskManager`.

+### User `SpillFile` traits instead of [`RefCountedTempFile`]
+
+Spill file APIs now use the `datafusion_execution::SpillFile` trait instead of
+the concrete [`RefCountedTempFile`] type. [`DiskManager::create_tmp_file`] now
+returns `Arc<dyn SpillFile>`.
+This change was introduced in [PR #21882], which adds pluggable spill file
+backends via `SpillFile` and `TempFileFactory`.
+
+If your code matched on [`DiskManagerMode`], add a `DiskManagerMode::Custom(_)`
+arm.
+
+If your code wrote directly to a [`RefCountedTempFile`] or called
+[`RefCountedTempFile::update_disk_usage`], open a spill writer instead:
+
+```diff
+- temp_file.inner().as_file().write_all(bytes)?;
+- temp_file.update_disk_usage()?;
++ temp_file.open_writer()?.write_all(bytes)?;
+```
+
+Use `temp_file.size()` instead of [`RefCountedTempFile::current_disk_usage`].

Subject: [PATCH 371/878] fix: surface BufferExec input panics instead of
 silently truncating output (#23243)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this close?

Closes #23242.

## Rationale for this change

When the input to a `BufferExec` panics, the panic unwinds the
background producer task (`MemoryBufferedStream`), tokio catches it at
the task boundary, and the dropped sender looks like a clean
end-of-stream to the consumer. A panic isn't a `Result::Err`, so it also
skips the `batch_tx.send(Err(..))` path — the partition gets silently
truncated and the query returns partial results instead of failing. More
detail in #23242.

## What changes are included in this PR?

Catch the panic at the input poll inside `MemoryBufferedStream` and
forward it as a `DataFusionError` over the channel the consumer already
drains, so it propagates instead of being swallowed.

I went with surfacing it as an error rather than re-raising via
`join_unwind` (the way `RecordBatchReceiverStream` does), since the
consumer already handles `Some(Err(..))` and this fails only the query.
Happy to switch to a re-raise if that's preferred for consistency.

## Are these changes tested?

Yes — added `panic_in_input_is_propagated`, which feeds a stream that
panics partway through and asserts the buffered stream yields an error
instead of finishing cleanly.

## Are there any user-facing changes?

A query whose input panics under a `BufferExec` now fails with an error
instead of silently returning truncated results. No API changes.

Subject: [PATCH 372/878] fix: apply recursive CTE column-list aliases to the
 static term (#23098)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23097.

## Rationale for this change

`WITH RECURSIVE t(n) AS (...)` failed to plan because the CTE's declared
column-list names (the `t(n)` part) were never applied to the recursive
working relation. They were applied (via `apply_table_alias`) only after
the whole CTE plan was built, but the working table is derived from the
static term's schema *before* that — so the self-reference couldn't
resolve the declared names and planning failed with `Schema error: No
field named n. Valid fields are t."Int64(1)".`. PostgreSQL and DuckDB
accept the query; aliasing inside the static `SELECT` (`SELECT 1 AS n`)
was the only workaround.

## What changes are included in this PR?

Apply the column-list aliases to the static term inside
`recursive_cte()`, before the work table is created, so the working
relation and the self-reference carry the declared names. The caller now
applies only the relation-name alias on the recursive path (the columns
are already applied), avoiding a redundant projection on top of the
`RecursiveQuery` node. The non-UNION fallback applies the aliases
directly; non-recursive CTEs are unchanged. A column/alias-count
mismatch is now reported at the static term — a clearer error than the
previous "No field named …".

## Are these changes tested?

Yes, added `cte.slt` cases for single- and multi-column column-list
recursive CTEs (asserting the recursion produces the expected rows),
`UNION (DISTINCT)`, the arity-mismatch error, and an `EXPLAIN` locking
the plan shape (no extra projection over `RecursiveQuery`).

## Are there any user-facing changes?

`WITH RECURSIVE t(n) AS (...)` and multi-column column lists now plan
and execute correctly, matching PostgreSQL/DuckDB. No API changes.

*Note: this pull request was created together with AI tools (claude
code), the full diff was reviewed by myself in full prior to submission*

Subject: [PATCH 373/878] Avoid repeated `EmitTo::First` in partial hash
 aggregate output (#23250)

## Which issue does this PR close?

- Closes #23249.

## Rationale for this change

The migrated partial hash aggregate output path still used
`EmitTo::First(batch_size)` when draining grouped aggregate state in
batches.

For terminal output this is unnecessary and can be expensive:
`EmitTo::First` is not just slicing the first N rows, it also shifts
remaining group indexes and maintains `GroupValues` lookup state. For
high-cardinality partial aggregate output, this can cause repeated work
during output draining.

The final hash aggregate path already avoids this by materializing
output once with `EmitTo::All` and then slicing the resulting
`RecordBatch`. This PR applies the same approach to partial hash
aggregate output.

## What changes are included in this PR?

- Remove the helper that selected `EmitTo::First(batch_size)` for hash
aggregate terminal output.
- Change migrated partial hash aggregate output to:
  - materialize grouped keys and aggregate state once with `EmitTo::All`
- slice the materialized `RecordBatch` into `batch_size` chunks across
output polls
- Rename the shared materialized-output state/type to mode-neutral names
because it is now used by both final and partial output paths.
- Add a regression test with a custom `GroupsAccumulator` that fails if
partial terminal output calls `EmitTo::First(_)`.
- Strengthen the regression test to verify both batch slicing and
emitted key/state values.

## Are these changes tested?

Yes.

Local targeted tests:
```bash
cargo test -p datafusion-physical-plan partial_grouped_aggregate_materializes_before_slicing -- --nocapture
cargo test -p datafusion-physical-plan materialized_aggregate_output_slices_batches_until_exhausted -- --nocapture
git diff --check
```
Additional local verification run during development:

```bash
cargo test -p datafusion-physical-plan materialized_final_output_slices_batches_until_exhausted -- --nocapture
cargo test -p datafusion-physical-plan partial_grouped_aggregate_uses_raw_partial_stream -- --nocapture
```
The new regression test was also applied to the pre-fix baseline and
failed with the expected internal error when the partial output path
used `EmitTo::First`.
Local benchmark evidence was collected against the implementation commit
before the final test/naming polish commit.

## Are there any user-facing changes?
No. This is an internal physical execution change for hash aggregate
output draining. There are no public API or documented behavior changes.

Subject: [PATCH 374/878] Fix metrics for repartition when
 `preserve_order=true` (#20924)

## Which issue does this PR close?
Found this when working on
https://github.com/apache/datafusion/pull/20875/
<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change
Metric reporting was previously incorrect for `RepartitionExec` if
preserve order was set to true.
<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
Create new metrics before creating `PerPartitionStream`
## Are these changes tested?
Yes and confirmed that this fails on main:
```
     thread 'repartition::test::test_preserve_order_output_rows_not_double_counted' (12487869)
      panicked at datafusion/physical-plan/src/repartition/mod.rs:3007:9:
     assertion `left == right` failed: metrics output_rows (8) should match actual rows
     collected (4), not double-count
       left: 8
      right: 4
     note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 377/878] feat: Support interval type in approx_distinct
 (#23234)

## Which issue does this PR close?

- Relates to https://github.com/apache/datafusion/issues/22989 but does
not close it. More types are coming.

## Rationale for this change

- Support the `Interval` type for `approx_distinct`

- The Arrow type `Interval` in the `YearMonth`, `DayTime` and
`MonthDayNano` variant can be directly supported for
`NumericHLLAccumulator` and `HllGroupsAccumulator`

## What changes are included in this PR?

- Enable `NumericHLLAccumulator` and `HllGroupsAccumulator` to support
`Interval`.
- Tests for the non-grouped and grouped path as part of
`approx_distinct.rst` and `aggregate.slt`
- Benchmarks

## Are these changes tested?

Yes

## Are there any user-facing changes?

Yes, `approx_distinct` supports now `Interval` but no breaking changes.

Subject: [PATCH 378/878] feat: Re-spill sort stream if unable to reserve for 2
 streams (#22945)

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

I've encountered several cases where the merge reservation cannot
acquire the minimum reservation needed(2 streams, with a buffer size of
1), we currently error in these cases but that's not a necessity.
I've implemented a simple re-spill mechanism for when the first 2
streams cannot be reserved: we take the larger of those streams, and we
re-spill it with all its batches split in half(done using slice() so no
copying happens at that stage and we'll have a smaller memory peak)
This converges until we have enough memory to perform the merge(because
max_record_batch_size is halved, ideally)
I've encountered this in situations where there is heavy skew, so maybe
in the future might be worth it running this in general whenever one
stream has a max_record_batch_size that is far above the other streams,
could greatly improve performance of the entire merge stream at the cost
of re-spilling once.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Aforementioned implementation

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No

Subject: [PATCH 380/878] Add `Distribution::HashPartitioned` to
 `Distribution::KeyPartitioned` API bridge (#23259)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link to an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23236.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`HashPartitioned` is historical naming for a key-partitioning
requirement. This keeps the old variant as a deprecated compatibility
bridge while moving DataFusion internals to `KeyPartitioned`.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Adds `KeyPartitioned`, deprecates `HashPartitioned`, and treats both
equivalently during the transition to avoid breaking changes for
downstream consumers. A blast radius report on this was done here #23241

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

Yes, `Distribution::HashPartitioned` is deprecated and trainsitioned to
`Distribution::KeyPartitioned`.

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

## Which issue does this PR close?

Adds benchmark query for
https://github.com/apache/datafusion/issues/23237
Useful to test changes in
https://github.com/apache/datafusion/pull/23209

## Rationale for this change

Q16–Q22 existed in `hj.rs` but were missing `.benchmark` files, so they
were invisible to `bench.sh` and the CI benchmark bot. Q23 is a new
query reproducing a skewed high-fanout pattern where a single partition
does nearly all the join work -- almost all probe rows carry the same
key. Statistics are disabled to force `Partitioned` mode.

## What changes are included in this PR?

- `benchmarks/src/hj.rs`: adds Q23
- `benchmarks/sql_benchmarks/hj/benchmarks/q16–q23.benchmark`: sql
harness files for Q16–Q23 so they run via `bench.sh` and the CI
benchmark bot

## Are these changes tested?

These are benchmark additions, so no tests are needed.


## Are there any user-facing changes?

No

Subject: [PATCH 382/878] Restrict trigger push branch for GitHub Workflow
 (#23278)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Feature branches rarely need their own CI runs: the code is already
tested when a pull request is opened against a release branch. If the
push trigger has no branch restriction and pull_request is also
configured, every push to a branch with an open PR runs the workflow
twice: once for the push and once for the PR synchronisation.

Always give the push trigger an explicit list of branches: this stops
branches created from a release branch from inheriting its workflow
runs.

Subject: [PATCH 383/878] docs: show struct-returning aggregate window metadata
 pattern (#23248)

## Which issue does this PR close?

- Closes #16453.

## Rationale for this change

Issue #16453 asks how an extension can expose window metadata such as
`window_start`, `window_end`, and `window_duration` when grouping with a
custom window assignment function.

The earlier nullary aggregate UDF direction in #23038 turned out to be
the wrong abstraction: generic aggregate accumulators need real input
arrays for row context and normal multi-stage aggregate execution. In
the issue and PR discussion, @alamb suggested modeling this as a
selector-style aggregate that receives real input columns and returns a
struct containing both the metadata and aggregate result.

## What changes are included in this PR?

This PR documents and tests that struct-returning aggregate pattern:

- Adds UDAF integration tests for an `augmented_avg(time, value)`
aggregate returning a struct with `window_start`, `window_end`,
`window_duration`, and `avg_value`.
- Shows direct SQL field projection from the returned struct, for
example `augmented_avg(time, value)['window_start']`.
- Adds a test-only `session_window(time, INTERVAL ...)` grouping UDF to
demonstrate how an extension can assign rows to windows while the
aggregate derives metadata from real input columns.
- Adds library user guide documentation for returning multiple values
from an aggregate UDF.
- Adds a runnable `datafusion-examples` UDF example for the same
pattern.

This intentionally does not add nullary aggregate UDF support and does
not add first-class planner support for bare virtual columns such as
`SELECT window_start`.

## Are these changes tested?

Yes. I ran:

- `cargo run --example udf -- struct_udaf`
- `ci/scripts/check_examples_docs.sh`
- `cargo test -p datafusion --test user_defined_integration
test_augmented_avg`
- `cargo fmt --all -- --check`
- `ci/scripts/doc_prettier_check.sh`
- `git diff --check`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `./dev/rust_lint.sh`

## Are there any user-facing changes?

Yes. This adds documentation and an example for aggregate UDF authors.
There are no public API changes.

+### Returning multiple values from an Aggregate UDF
+
+An aggregate UDF can return a `DataType::Struct` when one aggregate result needs
+to carry multiple values. This is useful for time-windowing extensions that
+need to return metadata such as the window start, window end, and the aggregate
+value together.
+
+Pass the relevant input columns to the aggregate so the accumulator has enough
+information to update and merge state normally in multi-stage aggregate plans.
+For example, rows can be grouped into time buckets with the built-in `date_bin`
+function, while a struct-returning aggregate computes the value and carries
+metadata about each bucket:
+
+```sql
+SELECT
+  augmented_avg(time, value)['window_start'] AS window_start,
+  augmented_avg(time, value)['window_end'] AS window_end,
+  augmented_avg(time, value)['window_duration'] AS window_duration,
+  augmented_avg(time, value)['avg_value'] AS avg_value
+FROM t
+GROUP BY date_bin(INTERVAL '30 seconds', time)
+ORDER BY window_start;
+```
+
+In this pattern `date_bin(...)` assigns rows to a time bucket, while
+`augmented_avg(time, value)` is a normal aggregate UDF whose accumulator stores
+mergeable state such as `window_start`, `window_end`, `sum`, and `count`.
+The aggregate's `evaluate` method returns a `ScalarValue::Struct`, and callers
+can project individual fields from that struct.
+

Subject: [PATCH 384/878] feat: Expose cache hits in statistics_cache function
 (#23253)

## Which issue does this PR close?

- Closes None.

## Rationale for this change

Follow up to https://github.com/apache/datafusion/pull/22613. Cache hits
are now supported for all memory-limiting caches. Therefore it makes
sense to expose them in the `statistics_cache` function the same way the
`metadata_cache` function does it already.

## What changes are included in this PR?

- Add cache hits to the `statistics_cache` function
- Tests
- Adapt documentation for the `statistics_cache` function

## Are these changes tested?

Yes.

## Are there any user-facing changes?

Yes, the `statistics_cache` function supports now cache hits but no
breaking changes.

Subject: [PATCH 385/878] fix: unparse columns of stacked pushdown projections
 unqualified (#23176)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23138 .

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

For an optimized plan, common subexpression elimination can leave a
`SubqueryAlias` over two stacked `Projection`s (it factors a shared
expression
into an extra inner projection). The plan is correct; the unparser just
cannot
render it accurately.

When unparsing such a subquery, `unparse_table_scan_pushdown` pushes the
subquery alias down to the aliased table scan and rebases each
projection's
columns to that alias. That is correct for the projection directly above
the
scan, but an *outer* stacked projection sits over a derived table where
the
alias is no longer in scope, so rebasing its qualified pass-through
columns
emits references the surrounding query cannot resolve.

For the reproducer in the issue the generated SQL is (note the middle
`"o"."order_id"`):

```sql
... INNER JOIN (
  SELECT "o"."order_id", CASE WHEN "__common_expr_1" ... END AS "discount_pct_2"
  FROM (SELECT CAST("o"."discount_pct" ...) AS "__common_expr_1", "o"."order_id"
        FROM "warehouse"."main"."orders" AS "o")
) AS "o" ON ...
```

DuckDB rejects it with Binder Error: Referenced table "o" not found!,
because
"o" is only the base-table alias one level deeper, not visible in the
intermediate derived table.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

In unparse_table_scan_pushdown's Projection arm, detect the stacked
case:
if the recursive pushdown result is itself a Projection, this projection
sits over a derived table rather than directly over the aliased scan.
In that case, strip the table qualifier from the projection's
pass-through
columns so they reference the derived table's output unqualified,
instead of
being rebased to the (out-of-scope) scan alias. The projection is built
directly (Projection::try_new) so the unqualified columns are not
re-normalized back to the alias.
The projection directly above the scan is unchanged and still rebases to
the
alias.
After the fix the middle column is unqualified and the SQL is valid:

```sql
... INNER JOIN (
  SELECT "order_id", CASE WHEN "__common_expr_1" ... END AS "discount_pct_2"
  FROM (SELECT CAST("o"."discount_pct" ...) AS "__common_expr_1", "o"."order_id"
        FROM "warehouse"."main"."orders" AS "o")
) AS "o" ON ...
```

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

New test `optimized_duckdb_unparse_qualifies_nested_passthrough_column`
in
`datafusion/core/tests/sql/unparser.rs`, asserting the intermediate
derived
table no longer carries the out-of-scope alias.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No public API changes.

 datafusion.execution.enable_file_stream_work_stealing config (#23294)
MIME-Version: 1.0

## Which issue does this PR close?

- Closes #23293.

## Rationale for this change

`FileStream` sibling work-stealing (`WorkSource::Shared`, added in
#21351 and extended by #23285) seeds one shared work queue from every
file group and lets whichever output partition goes idle first steal the
next unopened file (or byte-range morsel). This assumes all output
partitions of a scan are polled concurrently in one process.

Executors that run each output partition as an isolated task in a
separate process — Ballista and datafusion-distributed — never poll the
sibling partitions. The single polled partition drains the whole shared
queue and reads files belonging to other partitions, so every isolated
task reads the entire input and the scan output is inflated by the
partition count. This is a correctness bug for those executors, not just
a performance one.

The existing escape hatches (`preserve_order`,
`partitioned_by_file_group`) are plan-level flags on `FileScanConfig`,
not something a distributed executor can set centrally through the
session config, and a plain repartitioned scan does not set
`partitioned_by_file_group`. There is no session-level off switch,
unlike `datafusion.optimizer.enable_dynamic_filter_pushdown`, which
exists precisely so consumers that cannot support runtime
cross-partition state can disable it.

## What changes are included in this PR?

- Add `datafusion.execution.enable_file_stream_work_stealing` (default
`true`). When `false`, `FileScanConfig::create_sibling_state` returns
`None`, so each partition falls back to `WorkSource::Local` and reads
only its own file group.
- Thread `&ConfigOptions` into `DataSource::create_sibling_state` so the
flag is read from the session config at `execute` time. As a session
config value it round-trips through `datafusion-proto` with no proto
schema change.
- Regenerate `configs.md` and add the setting to
`information_schema.slt`.
- Turn the previously `#[ignore]`d reproduction test into a passing
regression test that drives only partition 0 (as an isolated task does)
and asserts both behaviors: with the default (stealing on) partition 0
also reads partition 1's file, and with the flag off it reads only its
own.

## Are these changes tested?

Yes. `isolated_partition_respects_work_stealing_config` in
`datafusion/datasource/src/file_stream/mod.rs` covers both the default
(shared-queue) behavior and the flag-off behavior. The existing sibling
work-stealing tests continue to pass with the default.
`information_schema` sqllogictests pass with the new setting listed.

## Are there any user-facing changes?

A new session config,
`datafusion.execution.enable_file_stream_work_stealing` (default
`true`), so existing behavior is unchanged.
`DataSource::create_sibling_state` gains a `&ConfigOptions` parameter
(an API change for anyone implementing the `DataSource` trait directly).

 datafusion.execution.enable_ansi_mode false Whether to enable ANSI SQL mode. The flag is experimental and relevant only for DataFusion Spark built-in functions When `enable_ansi_mode` is set to `true`, the query engine follows ANSI SQL semantics for expressions, casting, and error handling. This means: - **Strict type coercion rules:** implicit casts between incompatible types are disallowed. - **Standard SQL arithmetic behavior:** operations such as division by zero,   numeric overflow, or invalid casts raise runtime errors rather than returning   `NULL` or adjusted values. - **Consistent ANSI behavior** for string concatenation, comparisons, and `NULL` handling. When `enable_ansi_mode` is `false` (the default), the engine uses a more permissive, non-ANSI mode designed for user convenience and backward compatibility. In this mode: - Implicit casts between types are allowed (e.g., string to integer when possible). - Arithmetic operations are more lenient — for example, `abs()` on the minimum   representable integer value returns the input value instead of raising overflow. - Division by zero or invalid casts may return `NULL` instead of failing. # Default `false` — ANSI SQL mode is disabled by default.
+datafusion.execution.enable_file_stream_work_stealing true When `true` (the default), DataFusion's built-in file scans dynamically rebalance files across partitions at query execution time: a partition that goes idle reads files (or byte-range morsels) originally assigned to a sibling partition, which keeps all partitions busy in a single process. Executors that depend on the plan-time partition assignment — such as Ballista and datafusion-distributed, which run each partition as an isolated task and never poll the siblings — should set this to `false` so each partition reads only its own file group and no runtime reassignment occurs.
 datafusion.execution.enable_migration_aggregate true Temporary switch for aggregate stream implementations that are being migrated from `GroupedHashAggregateStream`. When set to true, DataFusion tries the migrated implementations when their preconditions are satisfied. When set to false, grouped aggregation falls back to `GroupedHashAggregateStream`. This option will be removed after the migration is finished. See <https://github.com/apache/datafusion/issues/22710> for details.
 datafusion.execution.enable_recursive_ctes true Should DataFusion support recursive CTEs
 datafusion.execution.enforce_batch_size_in_joins false Should DataFusion enforce batch size in joins or not. By default, DataFusion will not enforce batch size in joins. Enforcing batch size in joins can reduce memory usage when joining large tables with a highly-selective join filter, but is also slightly slower.

Subject: [PATCH 387/878] Aggregations Support `Partitioning::Range` (#23239)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23191.
- Related discussion: #23184, #23236.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Range partitioning can satisfy aggregate hash partitioning: equal group
keys are already partitioned, even though the partitioning is not
hash-based.

This is the first unary-operator implementation from the range
partitioning discussion before making broader public API changes around
`HashPartitioned` / `KeyPartitioned`.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Let compatible range partitioning satisfy aggregate hash distribution
requirements in `EnforceDistribution`
- Keep this private to aggregate planning for now to not make public API
changes to `Distribution` enum variants yet until more operators are
supported

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

Yes. Range-partitioned aggregate plans can now avoid hash

Subject: [PATCH 388/878] fix(sort): record output_batches, output_bytes and
 end_time for when not using merge sort (#22878)

## Which issue does this PR close?

N/A

## Rationale for this change

When only using in mem sort without going through the
`StreamingMergeBuilder` some metrics are not being recorded

## What changes are included in this PR?
wrap in `ObservedStream` for streams that returned to the next operator

## Are these changes tested?
yes

## Are there any user-facing changes?
no

Subject: [PATCH 389/878] fix: Handle decimal columns consistently in SLT tests
 (#23161)

## Which issue does this PR close?

- Closes #23160.

## Rationale for this change

As described in the issue, different width decimals are currently
handled differently, going through inconsistent display path and not
presenting the full precision.


## What changes are included in this PR?

1. Unifies all handling and formatting for the four decimal variants,
which are now all supported. Also includes full display of decimal
values up to the specified precision, which should be deterministic.
2. I've also reran the all tests with `--complete`, which makes a few
random changes around empty whitespaces which I think is good to run
periodically (I keep doing that locally in unrelated changes and having
to `git restore` a bunch of files). Would it make sense to maybe add
this check to CI and verify it leaves the worktree clean?

## Are these changes tested?

Ran all tests locally

## Are there any user-facing changes?

Users of `datafusion-sqllogictest` will get different results if they
depend on the existing behavior.

Subject: [PATCH 390/878] refactor(hash-aggr): Migrate ordered partial/final
 aggregation (#23181)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Part of https://github.com/apache/datafusion/issues/22710

This PRs implements the cases that input is ordered by group keys.

Comments at
datafusion/physical-plan/src/aggregates/ordered_partial_stream.rs
explains the high-level idea.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
1. Implement two aggregate tables for ordered partial/final aggregates.
It provides a simple abstraction to the control flow: its logically a
map from group keys to group states, and internally handles the
low-level details
2. Implement two streams for ordered partial/final aggregates

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
3. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

+/// The table consumes input batches while `GroupOrdering` tracks which groups

+/// ends, which keeps memory bounded by the active ordered key range.
+///
+/// # Partial and final variant difference
+///
+/// The partial and final aggregate tables implement the two stages of grouped
+/// aggregation. See
+/// [`OrderedPartialAggregateStream`](crate::aggregates::ordered_partial_stream::OrderedPartialAggregateStream)
+/// for the high-level plan shape.
+///
+/// Example: `AVG(v) FILTER (WHERE v>0) GROUP BY k`
+///
+/// Partial table ([`AggregateMode::Partial`], with optional filter from query):
+/// - Input rows: `k, v`
+/// - Table stores: `k, sum(v), count(v)`
+/// - Output schema: `k, sum(v), count(v)`
+///
+/// Final table ([`AggregateMode::Final`], no filters):
+/// - Input rows: `k, sum(v), count(v)`
+/// - Table stores: `k, sum(v), count(v)`
+/// - Output schema: `k, avg(v)`
+///
+/// # Marker Type
+///
+/// `OrderedAggrMode` selects the aggregate semantics. For example,
+/// `OrderedAggregateTable::<PartialMarker>::new(...)` consumes raw rows
+/// and emits partial states, while
+/// `OrderedAggregateTable::<FinalMarker>::new_with_input_order(...)`
+/// consumes partial states and emits final values.
+///
+/// Shared methods live on `impl<T>`; partial/final behavior lives on
+/// marker-specific impls.

+/// Partial aggregate stream for `InputOrderMode::Sorted` and
+/// `InputOrderMode::PartiallySorted`.
+///
+/// # Example
+///
+/// SELECT k, AVG(v) FROM t GROUP BY k;
+///
+/// If the input is ordered by `k`, the aggregate can use ordered partial and
+/// final stages:
+///
+/// ## Plan
+/// AggregateExec(stage=final, ordered)
+/// -- RepartitionExec(hash(k), preserves_order=true)
+/// ---- AggregateExec(stage=partial, ordered)
+///
+/// ## Partial Stage Behavior
+/// Input: raw rows
+/// Output: partial states for all groups (for example, `AVG(x)` emits `SUM(x)`
+/// and `COUNT(x)`)
+///
+/// ## Final Stage Behavior
+/// Input: partial states
+/// Output: results for all groups (for example, `AVG(x)` calculated from the
+/// state)
+///
+/// # Order-based Optimization
+///
+/// For the aggregation work, the hash aggregation implementation is reused.
+///
+/// After each input batch, check whether any groups can be emitted eagerly to
+/// improve memory efficiency. For example, if the last group key seen is
+/// `k = 100`, it is safe to emit all groups with keys less than 100 because the
+/// input is ordered.
+///
+/// ## Implementation Note
+///
+/// This is intentionally kept simple and closely maps to
+/// `GroupedHashAggregateStream` to finish the refactor sooner.
+///
+/// See issue for details: <https://github.com/apache/datafusion/issues/22710>
+///
+/// More applicable optimizations are left to future work.

+The proposed refactor makes window function execution simpler and more extensible. I think it is a necessary step if we want to invest further in better vectorization or more parallel execution paradigms.
+
+The existing structure is not ideal: if we keep evolving the current shape, new optimization work will likely add more special cases and make the system harder to reason about.
+
+To sanity-check whether this refactor makes sense, we can use the potential optimizations mentioned in:
+
+- https://github.com/apache/datafusion/issues/23197
+
+The examples include better parallelism and vectorization for fixed frames, parallel execution for prefix frames, and segment-tree-based parallelism. These optimizations are natural extensions of the ideal architecture introduced by this issue, but they are hard to add cleanly with the existing structure.
+
+This issue explains, in order:
+
+- How an ideal structure should look
+- The issues in the existing implementation
+- A possible implementation plan
+
+### Ideal Architecture
+
+The gist is that we should fully separate the logical and physical layers of window execution.
+
+- Logical layer: `WindowCall` purely describes what we want to calculate. It contains the expressions for arguments, partitioning, ordering, and frame bounds.
+- Physical layer: `WindowKernel` purely provides the methods needed for execution. It represents the selected execution algorithm for a specific window call.
+
+This design brings below benefits:
+- Simplicity: the control flow is one directional, `WindowCall` decides what window kernel to use, and window kernel purely provide methods for execution.
+- Extensibility: adding new parallelism scheme/or improve vectorized fast path means adding one window kernel, no deep structural changes needed.
+
+#### Workflow
+
+```text
+SQL / logical physical planning
+  -> WindowCall              // pure description: function, args, partition/order/frame
+  -> WindowKernel selection  // physical execution protocol chosen from shape + capabilities
+  -> WindowExec              // execution routing: choose stream based on selected kernel
+      -> NaiveAccumulatorStream
+      -> SlidingAccumulatorStream
+      -> other specialized streams
+```
+
+In rough terms:
+
+```rust
+/// pure description: function, args, partition/order/frame
+struct WindowCall {
+    name: String,
+    field: FieldRef,
+    function: WindowFunctionKind,
+    args: Vec<Arc<dyn PhysicalExpr>>,
+    filter: Option<Arc<dyn PhysicalExpr>>,
+    partition_by: Vec<Arc<dyn PhysicalExpr>>,
+    order_by: Vec<PhysicalSortExpr>,
+    frame: Arc<WindowFrame>,
+    options: WindowOptions,
+}
+
+/// pure execution: provided methods needed for a specific path
+enum WindowKernel {
+    /// Derived from existing Accumulator without `retract_batch`
+    /// A nested-loop algorithm will be used.
+    NaiveAccumulator(Box<dyn NaiveAccumulatorWindowKernel>),
+    /// Derived from existing Accumulator with `retract_batch`
+    /// A sliding window algorithm will be.
+    SlidingAccumulator(Box<dyn SlidingAccumulatorWindowKernel>),
+}
+```
+
+DataFusion's existing `Accumulator` API already contains the primitives for two useful aggregate window algorithms:
+
+- `update_batch()` plus `evaluate()` can recompute a result for any frame. This supports a naive nested-loop fallback for all accumulators.
+- `retract_batch()` plus `supports_retract_batch()` allow incremental sliding-window execution when rows leave the frame.
+
+If the accumulator does not support `retract_batch()`, a naive nested-loop evaluation can be used. If `retract_batch()` is supported and the window frame is a fixed sliding frame, a sliding-window algorithm can be used for optimization.
+
+Then the implication for newly added user-defined window function is, it should only support the naive method to make it work universally (for aggregate function in window cases, it requires only `update_batch()` for the above naive path), but it can optionally support more fast paths (`retract_batch` for sliding window, or even vectorized API in the future), then the optimizer/execution will route that into the fast path if the query expression shape allows.
+
+Here is a simple example to walk through the above workflow.
+
+#### Workload 1: Sliding Aggregate
+
+Example query:
+
+```sql
+SELECT
+  avg(x) OVER (
+    PARTITION BY k
+    ORDER BY ts
+    ROWS BETWEEN 2 PRECEDING AND CURRENT ROW
+  ) AS avg_x
+FROM t;
+```
+
+Planning:
+
+1. `WindowCall` holds the logical description: `avg(x)`, `PARTITION BY k`, `ORDER BY ts`, and `ROWS BETWEEN 2 PRECEDING AND CURRENT ROW`.
+2. The planner sees that this is an aggregate window over a fixed moving frame.
+3. The planner asks the aggregate accumulator whether it supports `retract_batch()`. `avg` does;
+4. The planner chooses `SlidingAccumulatorWindowKernel`.
+5. `WindowAggExec` routes execution to a dedicated `SlidingAccumulatorStream`, because the selected kernel has the sliding-window execution protocol.
+
+The kernel API can stay small because it only represents one physical protocol:
+
+```rust
+trait SlidingAccumulatorWindowKernel {
+    fn evaluate_partition(
+        &mut self,
+        input: &PartitionWindowInput<'_>,
+        frame: &FrameIndex,
+    ) -> Result<ArrayRef>;
+}
+
+struct PartitionWindowInput<'a> {
+    batch: &'a RecordBatch,
+    args: Vec<ArrayRef>,
+    filter: Option<BooleanArray>,
+}
+```
+
+Very rough sliding-window algorithm sketch:
+
+```python
+acc = create_avg_accumulator()
+current_frame = range(0, 0)
+output = []
+
+for row_idx in partition_rows:
+    next_frame = frame_for(row_idx)
+
+    # Rows that were in the previous frame but are not in the next frame.
+    leaving = current_frame.start .. next_frame.start
+    if leaving is not empty:
+        acc.retract_batch(values_for(leaving))
+
+    # Rows that are in the next frame but were not in the previous frame.
+    entering = current_frame.end .. next_frame.end
+    if entering is not empty:
+        acc.update_batch(values_for(entering))
+
+    output.append(acc.evaluate())
+    current_frame = next_frame
+```
+
+This is the fast path: each input row is added and removed at most once, so the cost is linear in the partition size for row-based fixed frames.
+
+#### Workload 2: Naive Aggregate Fallback
+
+Example query:
+
+```sql
+SELECT
+  my_udaf(x) OVER (
+    PARTITION BY k
+    ORDER BY ts
+    ROWS BETWEEN t.n_gap PRECEDING AND CURRENT ROW
+  ) AS v
+FROM t;
+```
+
+Assume `my_udaf` is a user-defined aggregate accumulator that supports `update_batch()` and `evaluate()`, but does not support `retract_batch()`. Also the window frame `t.n_gap` preceding can be arbitrary value, it's not supported by the sliding window algorithm.
+
+Planning:
+
+1. `WindowCall` holds the logical description: `my_udaf(x)`, `PARTITION BY k`, `ORDER BY ts`, and `ROWS BETWEEN 2 PRECEDING AND CURRENT ROW`.
+2. The planner sees that this is an aggregate window (without `retract_batch()` capability), and also over a non-fixed moving frame.
+3. The planner chooses `NaiveAccumulatorWindowKernel`.
+4. `WindowAggExec` routes execution to a dedicated `NaiveAccumulatorStream`.
+
+The kernel API can again stay small:
+
+```rust
+trait NaiveAccumulatorWindowKernel {
+    fn evaluate_partition(
+        &self,
+        input: &PartitionWindowInput<'_>,
+        frame: &FrameIndex,
+    ) -> Result<ArrayRef>;
+}
+```
+
+Naive nested-loop algorithm sketch:
+
+```python
+output = []
+
+for row_idx in partition_rows:
+    frame = frame_for(row_idx)
+
+    # This is slower, but it only needs update_batch() and evaluate().
+    acc = create_my_udaf_accumulator()
+    acc.update_batch(values_for(frame))
+
+    output.append(acc.evaluate())
+```
+
+### Issue with existing implementation
+The major issue is that the existing abstraction layers leak into adjacent layers. I think the original design goal was:
+
+- `WindowExpr` is supposed to be the logical layer.
+- `PartitionEvaluator` is supposed to be the physical layer.
+
+Over time, however, these responsibilities have become mixed. The decision-making flow has become bidirectional, and the implementation now relies on special cases to work around abstraction leaks.
+
+My guess is that these are mostly hacks accumulated over the years. I cannot find a strong reason to preserve this design.
+
+### Implementation Plan
+
+I plan to do some prototyping to work out a practical refactoring plan. The known goals are:
+
+- Remove all three `WindowExpr` implementations and use `WindowCall` as the pure logical layer.
+- Use `WindowKernel` to replace the `PartitionEvaluator`
+    - `PartitionEvaluator` is now a large trait that uses 3+ flags to decide behavior. I think it is hard to use and extend; small, focused traits inside `WindowKernel` enum variants should be better.
+    - Provide an adapter like `WindowKernel::LegacyPartitionEvaluator` to make the refactor practical.
+- Evolve `WindowAggExec` in this direction and avoid changing `BoundedWindowAggExec`
+    - See https://github.com/apache/datafusion/issues/23197#issuecomment-4806401319

- Closes #23297.

## Rationale for this change

The audit workflow is failing on main due to the quick-xml advisories:

- RUSTSEC-2026-0194
- RUSTSEC-2026-0195

quick-xml is pulled in transitively through object_store, and the
released object_store version currently used by DataFusion does not yet
depend on quick-xml >= 0.41.0.

## What changes are included in this PR?

This temporarily ignores the two quick-xml RustSec advisories in the
audit workflow and documents that the ignores should be removed once
object_store upgrades to quick-xml >= 0.41.0.

This is what I did in arrow-rs as well
- https://github.com/apache/arrow-rs/pull/10267


## Are these changes tested?

By CI


## Are there any user-facing changes?

No.

+/// ## Plan
+/// AggregateExec(stage=final)

Subject: [PATCH 393/878] fix(`EnsureRequirements`): remap sort requirement
 through `ProjectionExec` on pushdown (#23199)

## Which issue does this PR close?

None (Happy to open a tracking issue if preferred).

## Rationale for this change

`EnforceSorting`/`EnsureRequirements` can produce a physically invalid
plan that `SanityCheckPlan` rejects:

```
... does not satisfy order requirements: [score@1 DESC NULLS LAST, id@0 ASC]. Child-0 order: []
```

**Root cause.** In `sort_pushdown.rs::pushdown_requirement_to_children`,
the fetch-forwarding branch

```rust
} else if plan.fetch().is_some()
    && plan.supports_limit_pushdown()
    && plan.maintains_input_order().into_iter().all(|m| m)
{
    ... Ok(Some(vec![Some(parent_required)]))   // forwards the requirement UNCHANGED
}
```

forwards the parent ordering requirement to the child **unchanged**. A
`ProjectionExec` reports a `fetch()` (forwarded from its input) and can
renumber/reorder columns, so the requirement, expressed in the
projection's **output** schema, is pushed into the **child** schema
verbatim. For a projection that reorders the sort key (e.g. output `[id,
score, value]` over input `[id, value, score]`), `score@1` (valid above)
is pushed down as `score@1` (a different column below). The relocated
`SortExec` then advertises an ordering its child cannot provide, and
`SanityCheckPlan` fails.

This reproduces whenever a fetch-bearing global sort sits above a
`CoalescePartitionsExec` over a column-reordering, order-preserving
`ProjectionExec` whose input is already ordered, `parallelize_sorts`
sinks the per-partition `SortExec` below the projection without
remapping the key index.

## What changes are included in this PR?

Remap the ordering requirement through the projection's column mapping
before pushing it down (new `remap_requirement_through_projection`
helper):

- Each required column at output index `i` is rewritten to the column
the projection produces at that index (`projection.expr()[i]`).
- If any required column maps to a **computed** (non-`Column`)
expression, the ordering cannot be expressed below the projection, so
pushdown is declined and the sort is kept **above** the projection.
- Hard/soft-ness and all alternatives of the `OrderingRequirements` are
preserved; unsatisfiable alternatives are dropped.

For non-reordering projections the remap is the identity, so existing
plans are unchanged.

## Are these changes tested?

Yes.

- Unit tests for the remap helper: reordering remap, softness
preservation, multiple hard alternatives, dropping an unsatisfiable
alternative while keeping others, and declining when a required column
is computed.
- An end-to-end regression test
(`test_parallelize_sorts_remaps_index_through_reordering_projection`)
builds the multi-partition reordering-projection plan, runs
`EnsureRequirements` with `repartition_sorts` enabled, and asserts the
result passes `SanityCheckPlan`. It fails without this fix and passes
with it.

## Are there any user-facing changes?

No API changes. Plans that previously failed `SanityCheckPlan` (or
produced incorrect orderings) for this shape are now valid; all other
plans are unchanged.

Subject: [PATCH 395/878] Minor: Make `BloomFilterStatistics` and
 `RowGroupAccessPlanFilter::prune_by_bloom_filters` public (#23302)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- N/A

## Rationale for this change

`RowGroupAccessPlanFilter` is already public and re-exported at the
crate root, and its `prune_by_statistics`, `prune_by_range`, and
`prune_by_limit` methods are all `pub` — but `prune_by_bloom_filters` is
still `pub(crate)`, and `BloomFilterStatistics` (the `PruningStatistics`
adapter it consumes) is crate-private. So a custom `FileOpener` /
`TableProvider` that builds its own `ParquetAccessPlan` can prune row
groups by statistics, range, and limit through the public API, but has
to carry a copy of the bloom-filter evaluation code to prune by bloom
filters.

We hit this downstream: a custom parquet opener that scans row groups in
reverse order (for `ORDER BY ... DESC LIMIT k` workloads) currently
maintains a private copy of this logic. Making these two symbols public
lets such implementations reuse DataFusion's bloom-filter predicate
evaluation and brings `prune_by_bloom_filters` to parity with its
sibling `prune_by_*` methods.

## What changes are included in this PR?

- Make `BloomFilterStatistics` and its `new` / `with_capacity` /
`insert` methods `pub`, and re-export the type at the crate root. The
`bloom_filter` module itself stays private (matching how
`row_group_filter` is handled) to keep the added API surface minimal.
- Make `RowGroupAccessPlanFilter::prune_by_bloom_filters` `pub`.
- Drop the now-redundant `pub(crate)` re-export in `row_group_filter`
and route the `opener` import through the crate root.

Visibility only — no behavior change.

## Are these changes tested?

Covered by existing tests (`cargo test -p datafusion-datasource-parquet`
passes, including the `bloom_filter` pruning tests). No new behavior to
test.

## Are there any user-facing changes?

Two additions to the public API of `datafusion-datasource-parquet`:
`BloomFilterStatistics` (crate-root re-export) and
`RowGroupAccessPlanFilter::prune_by_bloom_filters`. No breaking changes.

Subject: [PATCH 396/878] Add basic sql benchmark runner for running sql
 benchmarks (#23052)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of #21937.

## Rationale for this change

Running sql benchmarks using environment variables for configuration is
awkward and error prone and strictly using criterion, while
statistically much better, is quite slow compared to using simple
iterations.

This PR is the first version of a benchmark runner for sql benchmarks
that will eventually use arguments for all benchmark configuration
options.

## What changes are included in this PR?

A simple benchmark runner that can list out the sql benchmarks and run a
benchmark using iterations or criterion allowing for specifying a single
query if desired.

Future enhancements will use arguments for benchmark configuration vs
just using environment variables as well as providing help and tying
this into bench.sh

## Are these changes tested?

Yes. I have a script that tests all current sql benchmarks both with and
without criterion. Here is an portion of it for the single clickbench
benchmark:
```
# clickbench single basic long flags
env DATA_DIR=data CLICKBENCH_TYPE=single cargo run -p datafusion-benchmarks --bin benchmark_runner -- clickbench --query 0 --iterations 5 --output results/benchmark_runner/clickbench_single_long.json

# clickbench single basic short flags
env DATA_DIR=data CLICKBENCH_TYPE=single cargo run -p datafusion-benchmarks --bin benchmark_runner -- clickbench --query 0 -i 5 -o results/benchmark_runner/clickbench_single_short.json

# clickbench single basic env iterations
env DATA_DIR=data CLICKBENCH_TYPE=single ITERATIONS=5 cargo run -p datafusion-benchmarks --bin benchmark_runner -- clickbench --query 0 --output results/benchmark_runner/clickbench_single_env_iterations.json

# clickbench single criterion with baseline
env DATA_DIR=data CLICKBENCH_TYPE=single cargo run -p datafusion-benchmarks --bin benchmark_runner -- clickbench --query 0 --criterion --save-baseline benchmark_runner_acceptance

# clickbench single criterion without baseline
env DATA_DIR=data CLICKBENCH_TYPE=single cargo run -p datafusion-benchmarks --bin benchmark_runner -- clickbench --query 0 --criterion
```
The existing `cargo bench` approach still works the same (criterion
only):
```
env DATA_DIR=data CLICKBENCH_TYPE=single BENCH_NAME=clickbench BENCH_QUERY=0 cargo bench -p datafusion-benchmarks --bench sql`
```

## Are there any user-facing changes?

No.

Subject: [PATCH 398/878] Optimize Int8 and Int16 integer IN filters (#23299)

## Which issue does this PR close?

- Part of https://github.com/apache/datafusion/issues/19241
- closes https://github.com/apache/datafusion/pull/23013

## Rationale for this change

This is an alternate implementation proposal for optimizing small
integer `IN` list from @geoffreyclaude

- https://github.com/apache/datafusion/pull/23013

The in #23013 does some shenangans, including rebuilding the Arrow array
data directly in order to probe a bitmap keyed by an unsigned type.
Handling signed small integer types directly keeps the implementation
simpler and avoids the extra array-data path while preserving the
compact bitmap representation for these small domains.

## What changes are included in this PR?

This updates the specialized `IN` list bitmap filter to handle `Int8`,
`UInt8`, `Int16`, and `UInt16` directly.

Signed small integer filters now map values to bitmap indexes by their
bit pattern, so negative values use the same compact bitmap domain as
their unsigned counterparts.

## Are these changes tested?

Yes. This adds coverage for signed `Int8` and `Int16` bitmap filters,
including boundary values and sliced arrays.

## Are there any user-facing changes?

No. This is an internal physical expression optimization for small
integer `IN` list filters.

Subject: [PATCH 399/878] feat: cap spill merge fan-in (#23066)

## Which issue does this PR close?

- Closes #22848.

## Rationale for this change

External sort merge phases currently select spill files based only on
memory reservation. With many small spills, a single phase can open
enough files to exceed the process file-descriptor limit.

## What changes are included in this PR?

- Add `datafusion.runtime.max_spill_merge_fan_in` (`0` preserves the
current unlimited behavior).
- Clamp non-zero values to at least 2 during merge selection so each
pass makes progress.
- Support builder configuration and dynamic SQL `SET` / `RESET` /
`SHOW`.
- Add unit, runtime SQL, SQLLogicTest, information schema, and generated
documentation coverage.

## Are there any user-facing changes?

Users can cap the number of spill files opened in one external merge
pass. The default remains unchanged.

## How was this change tested?

- `cargo test -p datafusion-execution
test_max_spill_merge_fan_in_builder_and_dynamic_update --lib`
- `cargo test -p datafusion-physical-plan spill_merge_fan_in --lib`
- `cargo test -p datafusion --test core_integration
test_max_spill_merge_fan_in_runtime_config`
- `cargo test -p datafusion-sqllogictest --test sqllogictests --
set_variable.slt`
- `cargo check -p datafusion`
- `cargo clippy -p datafusion-execution -p datafusion-physical-plan -p
datafusion --lib -- -D warnings`
- `cargo fmt --all -- --check`
- `dev/update_config_docs.sh`

-->

- Closes #22455 .

## Rationale for this change

Extend pre commit instructions for AI agents to involve contributor
machine to find issues before being committed. Each commit triggers a CI
which in its turn asks ASF Infra for their precious resources and if we
can find and fix as early as possible, much before utilizing ASF
resources, would be amazing

Subject: [PATCH 402/878] fix: avoid panic parsing non-ASCII runtime config
 values (#23316)

## Which issue does this PR close?

- Closes #22187

## Rationale for this change

Presence of a non-ascii character in the value while setting any
datafusion runtime variable was panicking.

## What changes are included in this PR?

Better handling/iteration on character-boundary, and emits plan error
now instead of panicking in case of such characters.

## Are these changes tested?

Yes. UTs have been updated to include such cases.

## Are there any user-facing changes?

No.

 errors (#23314)

## Which issue does this PR close?

enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example

-->

- Closes #.

## Rationale for this change

CI more and more often fails with HTTP errors, during downloading from
Cargo. This leads the entire CI needs to be rerun in the merge queue.
Adding retry for Cargo HTTP and network settings.

Example


https://github.com/apache/datafusion/actions/runs/28677739346/job/85055401549?pr=23313


```
error: failed to get `windows` as a dependency of package `sysinfo v0.39.5`
    ... which satisfies dependency `sysinfo = "^0.39.3"` (locked to 0.39.5) of package `datafusion v54.0.0 (/__w/datafusion/datafusion/datafusion/core)`

Caused by:
  failed to load source for dependency `windows`

Caused by:
  unable to update registry `crates-io`

Caused by:
  download of wi/nd/windows failed

Caused by:
  curl failed

Caused by:
  [55] Failed sending data to the peer (OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 0)
Error: Process completed with exit code 101.

Subject: [PATCH 404/878] fix: avoid global SQL stack guard mutation in
 unparser (#23284)

## Which issue does this PR close?

- Closes #23246.

## Rationale for this change

`datafusion-sql` used `StackGuard` to temporarily raise `recursive`'s
process-global minimum stack size while planning or unparsing deep SQL
structures. Because that global is shared across threads, one guard
could restore a lower value while another thread was still relying on
DataFusion's larger SQL red zone.

## What changes are included in this PR?

This PR replaces the scoped global mutation with local
`stacker::maybe_grow` checkpoints for the SQL planner/unparser recursion
paths that need a 256 KiB red zone. The public planning and unparsing
APIs are unchanged.

It also adds regressions covering both non-mutating stack growth and
deep unparsing while another thread repeatedly lowers `recursive`'s
global minimum to the default value.

## Are these changes tested?

Yes.

- `cargo test -p datafusion-sql --features recursive_protection`
- `cargo fmt --all --check`
- `cargo clippy -p datafusion-sql --all-targets --all-features -- -D
warnings`
- `cargo clippy --all-targets --all-features -- -D warnings`

## Are there any user-facing changes?

No.

Subject: [PATCH 405/878] Fix inexact partitioned TopK sort pushdown (#23301)

## Which issue does this PR close?

- None.

## Rationale for this change

Inexact sort pushdown keeps the `SortExec` because the source can
optimize for the requested ordering but cannot guarantee exact global
ordering. When the rewritten standalone `SortExec` is a
partition-preserving TopK over multiple partitions, each partition
applies a local TopK. A later coalesce can then concatenate those local
results, which can violate `ORDER BY ... LIMIT` semantics.

For example, with two partitions containing `[1, 100]` and `[2, 3]`,
`ORDER BY a ASC LIMIT 3` should return `1, 2, 3`, but the unmerged local
TopK path can return `1, 100, 2, 3`.

## What changes are included in this PR?

- Wrap standalone multi-partition inexact partition-preserving TopK
pushdown with `SortPreservingMergeExec` and preserve the TopK fetch on
the merge.
- Stop traversal after rewriting inexact `SortPreservingMergeExec ->
SortExec` and after inserting the standalone merge, so the newly
inserted child `SortExec` is not processed again as a standalone TopK.
- Add a plan regression test that asserts the final merge is inserted.
- Add an execution regression test using an inexact executable memory
source to assert the global TopK result is returned.

## Are these changes tested?

Yes:


I also verified the new execution regression fails on unmodified
`upstream/main`: the plan returns `1, 100, 2, 3` instead of the expected
global TopK result `1, 2, 3`.

## Are there any user-facing changes?

Yes. This fixes incorrect results for `ORDER BY ... LIMIT` queries when
inexact sort pushdown produces a standalone partition-preserving TopK
over multiple input partitions.

Subject: [PATCH 406/878] Add IN list sqllogictest test (and integer type
 coverage) (#23305)

## Which issue does this PR close?
- Part of https://github.com/apache/datafusion/issues/19241
- part of https://github.com/apache/datafusion/issues/23307
- Follow on to https://github.com/apache/datafusion/pull/23299

## Rationale for this change

We (mostly @geoffreyclaude ) are in the process of optimizing IN lists
with specialized implementations for various different data types.

@kosiew suggested in
https://github.com/apache/datafusion/pull/23299#issuecomment-4876519158
that we add SQL level coverage for the IN list optimizations to both
cover the dispatch logic as well as ensure everything works end to end.

> One small follow-up idea: it could be useful to add a public-path
regression through InListExpr::try_new_from_array, or a SQL-level test,
for Int8 and Int16 signed values.

## What changes are included in this PR?
1. Add `in_list.slt` file to specifically target the IN lists
2. Only add test coverage for integer types

note I think we should have significiantly more SLT coverage (list on
https://github.com/apache/datafusion/issues/23307) but to keep the
review small / understandable I plan to do it with several PRs

## Are these changes tested?

Only tests

## Are there any user-facing changes?

No

Subject: [PATCH 407/878] fix: Avoid panicing when stats are not available for
 a file group split (#23277)

## Which issue does this PR close?

- Closes https://github.com/apache/datafusion/issues/23219.

## Rationale for this change

The query from the issue:

```sql
SELECT   (((Cast(id AS BIGINT) % 1024) + 1024) % 1024) AS computed_bucket
FROM     profile
ORDER BY computed_bucket,
         Cast(id AS BIGINT) limit 10;
```

panics:

```
thread 'main' panicked at .../datafusion-datasource-54.0.0/src/statistics.rs:100:48:
index out of bounds: the len is 0 but the index is 0
```

The underlying issue is that the current code panics when files are
split by statistics and there are no statistics available for the column
where the sort order is defined in this case `computed_bucket`.

## What changes are included in this PR?

- Fix in `MinMaxStatistics` to check if there are stats available for a
given column
- Test

## Are these changes tested?

Yes

## Are there any user-facing changes?

No

Subject: [PATCH 408/878] fix: gate debug-only assertions in physical planner
 test test_optimization_invariant_checker (#23323)

## Which issue does this PR close?
- Closes #20786

## Rationale for this change
`test_optimization_invariant_checker` panics under `release-nonlto`
profile which has debug_assertions=false. Thus, we need to gate

## What changes are included in this PR?
Make sure debug_assertion required places are behind that gate

## Are these changes tested?
Yes and this is test only change.

```
cargo test physical_planner --profile release-nonlto
```

now passes since we skip these checks as they are not supported in that
profile

## Are there any user-facing changes?
No

Subject: [PATCH 409/878] feat: Support duration type in approx_distinct
 (#23291)

## Which issue does this PR close?

- Relates to https://github.com/apache/datafusion/issues/22989 but does
not close it. More types are coming.

## Rationale for this change

- Support the `Duration` type for `approx_distinct`
- The Arrow type `Duration` can be directly supported for
`NumericHLLAccumulator` and `HllGroupsAccumulator`

## What changes are included in this PR?

- Enable `NumericHLLAccumulator` and `HllGroupsAccumulator` to support
`Duration`
- Tests for the non-grouped and grouped path as part of `aggregate.slt`


## Are these changes tested?

Yes

## Are there any user-facing changes?

Yes, `approx_distinct` supports now `Duration` but no breaking changes.

Subject: [PATCH 410/878] feat: Allow datafusion-ffi to opt out of proto
 parquet (#22951)

## Which issue does this PR close?

N/A

## Rationale for this change

`datafusion-ffi` inherits `datafusion-proto` from the workspace. Because
`datafusion-proto` enables its `parquet` feature by default, downstream
crates that depend on `datafusion-ffi` also pull in
`datafusion-datasource-parquet`, `parquet`, and parquet compression
dependencies even when they do not need parquet-aware proto support.

Cargo features are additive, so downstream users cannot opt out by
disabling default features on their own direct `datafusion-proto`
dependency if the `datafusion-ffi -> datafusion-proto` edge has already
enabled defaults.

## What changes are included in this PR?

This PR makes the workspace `datafusion-proto` dependency default to
`default-features = false`, then lets crates opt into the previous
behavior explicitly.

For `datafusion-ffi`, the previous default behavior is preserved with a
new default `parquet` feature. Downstream users that want to avoid
parquet dependencies can now use `datafusion-ffi` with `default-features
= false`.

The FFI session table option bridge now gates `ConfigFileType::PARQUET`
usage behind the `datafusion-ffi/parquet` feature, while still
preserving parquet table option values in no-default builds.

## Are these changes tested?

Yes. Existing `datafusion-ffi` tests pass with default features and with
`--no-default-features`. The feature graph was also checked to confirm
that default `datafusion-ffi` still enables parquet, while
`datafusion-ffi --no-default-features` does not include
`datafusion-datasource-parquet`.

## Are there any user-facing changes?

Default behavior is unchanged. Users can now opt out of parquet-aware
proto support from `datafusion-ffi` by disabling `datafusion-ffi`
default features.

Subject: [PATCH 411/878] bench: add array_has array-needle benchmarks (#23335)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of https://github.com/apache/datafusion/issues/23334.

## Rationale for this change

In order to correctly characterize a performance improvement for
array_has with column needle, needed more benchmark cover.

## What changes are included in this PR?

Adds criterion benchmarks for `array_has` with an **array (column)
needle** — the path through `array_has_dispatch_for_array`, with no
functional change.

Groups added in `datafusion/functions-nested/benches/array_has.rs`:

- `array_has_array_i64` / `array_has_array_strings` — found / not-found
over list sizes 10/100/500.
- `array_has_array_null_patterns` — null patterns at list length 64: for
i64, no nulls (found + not found) / 30% nulls found / 30% nulls not
found / all null / null-fill collision; for Utf8, LargeUtf8, and
Utf8View, no-nulls / 30% nulls at both short (inline, ≤ 12 byte) and
long (> 12 byte, shared-prefix) element lengths, plus all-null.
- `array_has_array_by_size` — i64, 30% element nulls, not found, list
length 8..1024.
- `array_has_array_by_rows` — i64, 8 elems/row, 30% nulls, not found,
10K / 100K / 1M rows.

## Are these changes tested?

no functional change here

## Are there any user-facing changes?

no

Subject: [PATCH 412/878] feat: Support BinaryView type in approx_distinct
 (#23333)

## Which issue does this PR close?

- Relates to https://github.com/apache/datafusion/issues/22989 but does
not close it. More types are coming.


## Rationale for this change

- Support the `BinaryView` type for `approx_distinct`
- The Arrow type `BinaryView` can be directly supported for
`HLLAccumulator` and `HllGroupsAccumulator`

## What changes are included in this PR?

- Enable `HLLAccumulator` and `HllGroupsAccumulator` to support
`BinaryView`
- Tests for the non-grouped and grouped path as part of `aggregate.slt`

## Are these changes tested?

Yes

## Are there any user-facing changes?

Yes, `approx_distinct` supports now `BinaryView` but no breaking
changes.

Subject: [PATCH 413/878] refactor: make file-statistics cache keys
 schema-aware (#23201)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23072.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

File statistics are computed against a specific `file_schema` (their
`column_statistics` are positional, one per column), but the
file-statistics
cache was keyed only by table and path. Reading the same path under a
different
schema could therefore reuse statistics whose columns no longer line up,
panicking during statistics projection.

#22950 worked around this by **bypassing** the file-statistics cache
entirely for
anonymous explicit-schema reads — correct, but it gave up cache reuse
for them
(every such read recomputes statistics). #23072 asks to make the cache
itself
schema-aware so those reads can reuse the cache safely instead of
skipping it.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add `SchemaFingerprint` — the per-column `(name, data_type, nullable)`
of a
`file_schema`, in order — and `FileStatisticsCacheKey { table, path,
schema }`,
  and key the file-statistics cache on it (`FileStatisticsCache` is now
  `dyn Cache<FileStatisticsCacheKey, CachedFileMetadata>`).
- `ListingTable::do_collect_statistics_and_ordering` builds the key with
the
`file_schema` fingerprint and uses the shared cache directly. The #22950
bypass (`statistics_cache` helper / `schema_source`-based skip) is
removed:
different schemas now land in distinct entries (no stale cross-schema
reuse),
  while a repeated read of the same schema reuses its entry.
- The fingerprint deliberately **excludes** field/schema metadata (it
cannot
affect statistics, and including it would needlessly fragment the cache)
and
partition columns (partition statistics are computed separately, outside
this
  cache).
- Table-drop invalidation is unchanged: `drop_table_entries` matches on
`CacheKey::table_ref()`, which still returns the table, so all schema
variants
  for a dropped table are removed together.
- The list-files cache continues to key on `TableScopedPath`.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes.

- Updated the #22950 regression test
(`anonymous_parquet_stats_cache_with_explicit_wider_schema`): the wider
explicit-schema read now lands in its own cache entry (2 entries, was 1
under
the bypass) with correct statistics and no panic, and a repeated read of
that
  schema is served from the cache (a cache hit, no new entry).
- Added unit tests for `SchemaFingerprint`: it distinguishes nullability
and
  field order, and ignores field/schema metadata.
- `cargo test` for the `file_statistics` integration module and the
`datafusion-execution` cache tests (including `drop_table_entries`)
pass, along
  with `cargo fmt --all` and `cargo clippy --all-targets --all-features
  -- -D warnings` for the touched crates.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No change to query results, physical plans, or the serialized (proto)
wire
format; file statistics are computed exactly as before.

One public API change (please add the `api change` label): the
`FileStatisticsCache` type alias now uses `FileStatisticsCacheKey`
instead of
`TableScopedPath` as its key. Code that constructed keys for this cache
directly
must switch to `FileStatisticsCacheKey`. `SchemaFingerprint` and
`FileStatisticsCacheKey` are newly public; `TableScopedPath` remains
(still used
by the list-files cache). `cargo-semver-checks` will flag the key-type
change,
which is expected.

Subject: [PATCH 415/878] Add regression tests for hash-join dynamic filter
 expression policy (#23319)

## Which issue does this PR close?

* Part of #22772

## Rationale for this change

This change adds focused regression coverage for the current
dynamic-filter expression assembly performed by
`SharedBuildAccumulator::build_filter`. The intent is to make the
existing expression policy explicit before refactoring, ensuring that
future changes preserve the current pruning semantics for both
`CollectLeft` and `Partitioned` finalize paths.

## What changes are included in this PR?

* Add reusable test helpers for constructing `SharedBuildAccumulator`
instances, partition state, bounds, and pushdown strategies.
* Add unit tests covering `CollectLeft` dynamic-filter expression
assembly for:

  * membership-only filters,
  * bounds-only filters,
  * empty build data that should not update the dynamic filter.
* Add unit tests covering `Partitioned` dynamic-filter expression
assembly for:

* a single real partition with otherwise empty partitions (ensuring no
unnecessary `CASE` expression),
* canceled/unknown partitions (ensuring permissive fallback for unknown
routes).
* Add helper assertions that validate the structural shape of the
generated expressions (for example, `InListExpr`, `BinaryExpr`,
`CaseExpr`, and literal boolean expressions) rather than relying on
brittle textual representations.

## Are these changes tested?

Yes.

This PR adds the following unit tests:

* `collect_left_updates_with_membership_only`
* `collect_left_updates_with_bounds_only`
* `collect_left_empty_build_data_does_not_update_filter`
* `partitioned_one_real_partition_with_rest_empty_skips_case`
*
`partitioned_canceled_unknown_partitions_keep_unknown_routes_permissive`

These tests exercise the dynamic-filter expression policy without
changing production behavior.

## Are there any user-facing changes?

No. This PR only adds regression tests and does not change runtime
behavior.

## LLM-generated code disclosure

This PR includes LLM-generated code and comments. All LLM-generated
content has been manually reviewed.

Subject: [PATCH 419/878] IN LIST: add Float16 bitmap filter (#23311)

## Which issue does this PR close?

- Part of #19241.
- Based on #23299.
- Next in stack: #23014, after it is rebased onto this PR.

## Rationale for this change

#23299 extends the bitmap `IN` filter to the signed 1-byte and 2-byte
integer types by handling each logical Arrow type directly. `Float16` is
the remaining 2-byte primitive type that can use the same compact bitmap
idea: it has 65,536 possible bit patterns, so an 8 KiB bitmap can
represent every possible value.

This PR follows the same direct typed shape as #23299. It does not
reinterpret whole arrays as `UInt16`; instead, the `Float16` bitmap
filter maps each value to its IEEE-754 half-precision bit pattern with
`to_bits()`. That keeps the logical array type intact while preserving
bit-pattern equality semantics, including distinct NaN payloads and
`+0.0` versus `-0.0`.

## What changes are included in this PR?

- Adds `Float16Type` support to the existing `BitmapFilter`.
- Routes `DataType::Float16` constant-list filtering to that bitmap
path.
- Extends the existing type-combination coverage to include `Float16`.
- Adds focused coverage for slices, nulls, `NOT IN`, `+0.0` / `-0.0`,
and NaN payload bit patterns.
- Adds focused `in_list_strategy` benchmark rows for `Float16`.

## Are these changes tested?

Yes.

- `cargo fmt --all`
- `cargo test -p datafusion-physical-expr bitmap_filter_f16 --lib`
- `cargo test -p datafusion-physical-expr
test_in_list_from_array_type_combinations --lib`
- `cargo test -p datafusion-physical-expr --bench in_list_strategy
--no-run`
- `cargo clippy --all-targets --all-features -- -D warnings`

## Are there any user-facing changes?

No. This is an internal performance optimization only.

## Local benchmark snapshot

Built and run with `release-nonlto`, filtered to the new Float16 rows:

```bash
cargo bench -p datafusion-physical-expr --profile release-nonlto --bench in_list_strategy -- narrow_integer/f16 --save-baseline <baseline>
```

Compared baselines:
[#23299](https://github.com/apache/datafusion/pull/23299) ->
[#23311](https://github.com/apache/datafusion/pull/23311)

Method: directly compared Criterion's raw sample minima (`min(time /
iterations)`) from `sample.json`. Lower is better; changes within +/-5%
are treated as noise.

Summary: 6 relevant rows, 6 faster, 0 slower, 0 within +/-5%.

Subject: [PATCH 420/878] feat: support decimals in trunc UDF (#23320)

## Which issue does this PR close?

- Closes #22512

## Rationale for this change

Introduce Decimal support for `trunc` - for feature parity and to solve
overflowing issues with large integers

## What changes are included in this PR?

- Decimal support for scalar and array cases
- A helper for decimals
- SLTs

## Are these changes tested?

- Unit test for new math
- SLTs
- One specific SLT to showcase @neilconway case from #22512

## Are there any user-facing changes?

Subject: [PATCH 421/878] feat: add strictness metadata for scalar UDF null
 propagation and use it in outer join elimination (#23148)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Related to #13232.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Outer join elimination relies on proving that a filter rejects the
NULL-padding rows introduced by an outer join. DataFusion already
handles many built-in NULL-propagating expressions, but scalar UDFs did
not expose whether they preserve the same property.

```sql
SELECT t1.a
FROM t1 LEFT JOIN t2 ON t1.a = t2.x
WHERE abs(t2.y) > 5;
```

Rows produced by the unmatched side of the left join have `t2.y = NULL`.
Since `abs(NULL)` is also `NULL`, the predicate `abs(t2.y) > 5` cannot
evaluate to true for those rows. That means the left join can be safely
rewritten as an inner join. Without function-level null propagation
metadata, the optimizer has to treat scalar functions conservatively and
misses this rewrite.

This PR adds `ScalarUDFImpl::is_strict()` to let scalar UDF
implementations declare that they always return NULL when any argument
is NULL. The default is `false` so existing UDFs remain conservative.
Optimizer rules can then use this metadata when reasoning about
expression nullability and null-rejecting predicates.

This design follows a pattern used by other query engines. PostgreSQL
exposes `STRICT / RETURNS NULL ON NULL INPUT` on functions, and
documents that such functions are not executed when any argument is
NULL; a NULL result is assumed automatically. DuckDB similarly has
function null-handling metadata, with default NULL-in/NULL-out behavior
and special handling for functions that do not follow that rule.

References:

- PostgreSQL `CREATE FUNCTION: STRICT / RETURNS NULL ON NULL INPUT`
  https://www.postgresql.org/docs/current/sql-createfunction.html

- DuckDB `FunctionNullHandling` definition

https://github.com/duckdb/duckdb/blob/main/src/include/duckdb/function/function.hpp

- DuckDB scalar function null-handling API

https://github.com/duckdb/duckdb/blob/main/src/include/duckdb/function/scalar_function.hpp

## What changes are included in this PR?

- Adds `ScalarUDFImpl::is_strict()`, defaulting to false.
- Adds `ScalarUDF::is_strict()` as the public forwarding API.
- Marks `abs` as strict.
- Uses strict scalar functions in predicate/nullability reasoning and
outer join elimination.
- Propagates `is_strict` through `datafusion-ffi::FFI_ScalarUDF`.
- Adds unit and slt coverage for strict and non-strict scalar UDF
behavior.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes.

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

Yes. Scalar UDF authors can now override ScalarUDFImpl::is_strict() to
tell the optimizer that their function always returns NULL when any
argument is NULL.

This PR also changes the FFI_ScalarUDF layout to propagate strictness
across the FFI boundary, so it should carry the api change label.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

## Future work

- Mark more built-in scalar functions as strict where the behavior is
clearly NULL-in/NULL-out.
- Reuse `is_strict()` in other optimizer rules to infer `arg IS NOT
NULL` from predicates like `strict_func(arg) > 0`.
- Use inferred non-null predicates to simplify redundant `IS NOT NULL`
checks and push filters closer to scans.
- Use strictness in statistics/selectivity estimation by deriving
tighter nullability information for function outputs.

Subject: [PATCH 422/878] fix: Reject out-of-range `ArrayMap` probe keys on
 32-bit targets (#22911)

## Which issue does this PR close?

- Closes #22910

## Rationale for this change

`ArrayMap` bucket lookups computed `key.wrapping_sub(offset) as usize`,
and then bounds-checked the result after the cast. On 64-bit hosts, that
is fine, but on 32-bit hosts, the cast will truncate the computed bucket
offset to its low 32 bits. Given a large probe key whose low 32 bits are
a valid bucket array index, this can produce incorrect results.

## What changes are included in this PR?

* Introduce `key_to_index` and `get_value` helpers, to consolidate
bucket lookup logic into one place
* Fix bucket lookup logic for 32-bit hosts
* Tweak null logic to optimize hot path slightly
* Other minor refactorings / comment fixes
* Add unit test

## Are these changes tested?

Yes; new test added.

## Are there any user-facing changes?

No.

Subject: [PATCH 426/878] minor: rename aggregate stream modules to match
 contents (#23372)

## Which issue does this PR close?

- Part of https://github.com/apache/datafusion/issues/22710

## Rationale for this change

@Rachelint and @2010YOUY01 and I are working to refactor the grouping
code into a more understandable structure. Part of this is the names of
modules.

Several aggregate stream implementations are stored in modules whose
file names do not match the primary stream types they contain. This
makes the aggregate module harder to scan because some stream files use
the `_stream.rs` suffix while others are named with other styles.

## What changes are included in this PR?

This PR renames aggregate stream modules so their filenames match the
stream implementations more closely:

- `no_grouping.rs` -> `aggregate_stream.rs`
- `hash_aggregate.rs` -> `hash_stream.rs`
- `row_hash.rs` -> `grouped_hash_stream.rs`
- `topk_stream.rs` -> `grouped_topk_stream.rs`

It also updates private module declarations, imports, and doc
links/comments that referenced the old module names.

## Are these changes tested?

No new tests are included because this is a module/file rename with no
behavioral changes.

## Are there any user-facing changes?

No. These modules are private implementation details of
`datafusion-physical-plan`.

Subject: [PATCH 427/878] test: cover float IN list predicates (#23373)

## Which issue does this PR close?

- part of https://github.com/apache/datafusion/issues/23307

## Rationale for this change

As @geoffreyclaude adds additional special implementations for IN lists
we should keep up with slt test coverage. Recently we added coverage for
floats
- https://github.com/apache/datafusion/pull/23311

## What changes are included in this PR?

This adds sqllogictest coverage for Float16, Float32, and Float64 `IN`
list predicates in `in_list.slt`, mirroring the existing integer `IN`
list coverage shape:


## Are these changes tested?
Yes -- all tests
## Are there any user-facing changes?

No. This only adds test coverage.

@@ -496,6 +496,49 @@ The ClickBench[1] benchmarks are widely cited in the industry and
 focus on grouping / aggregation / filtering. This runner uses the
 scripts and queries from [2].
 
+The runner applies two ClickBench-specific setup steps automatically:
+
+- ClickBench stores `EventDate` as `UInt16` days since `1970-01-01`.
+  The runner registers the parquet data as `hits_raw`, then creates a
+  `hits` view that casts `EventDate` through `INTEGER` to `DATE` for the
+  benchmark queries.
+- The source partitioned ClickBench dataset stores string columns without
+  the `string` Parquet logical type annotation. For partitioned runs, the
+  runner enables the parquet `binary_as_string` option so those columns
+  are read as strings.
+
+If you set up ClickBench manually through SQL, use the same `EventDate`
+view pattern:
+
+```sql
+CREATE EXTERNAL TABLE hits_raw
+STORED AS PARQUET
+LOCATION 'benchmarks/data/hits.parquet';
+
+CREATE VIEW hits AS
+SELECT * EXCEPT ("EventDate"),
+       CAST(CAST("EventDate" AS INTEGER) AS DATE) AS "EventDate"
+FROM hits_raw;
+```
+
+For the partitioned dataset, use `benchmarks/data/hits_partitioned` and
+add `OPTIONS ('binary_as_string' 'true')` to the external table statement.
+
+From the repository root, download data and run the default ClickBench
+queries against the single parquet file:
+
+```shell
+./benchmarks/bench.sh data clickbench_1
+./benchmarks/bench.sh run clickbench_1
+```
+
+Or run against the partitioned dataset:
+
+```shell
+./benchmarks/bench.sh data clickbench_partitioned
+./benchmarks/bench.sh run clickbench_partitioned
+```

<li><code>MANIFEST.in</code> matching (via <code>FileList</code>) is now

normalization form. A pattern authored in one form (e.g. NFC, as
typically
saved by editors) now matches a file whose name is stored on disk in
another
(e.g. NFD, as produced by macOS APFS/HFS+). Previously an
<code>exclude</code>,
<code>global-exclude</code>, <code>recursive-exclude</code>, or
<code>prune</code> rule could silently
fail to drop a non-ASCII-named file from the source distribution,
publishing
it despite the exclusion -- see GHSA-h35f-9h28-mq5c.</li>

Subject: [PATCH 431/878] fix: return execution error instead of capacity
 overflow panic in array_resize (#23306)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?
- Closes #22227..

## Rationale for this change
Please check #22227

## What changes are included in this PR?
Instead of panicking we return execution error buy checking sizes in
array_resize.

Outcome is:
```
➜  datafusion git:(fix-array-resize-overflow-panic)  cargo run -p datafusion-cli -- -c "SELECT array_resize(make_array(1), 9223372036854775807, 0)"
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.54s
     Running `target/debug/datafusion-cli -c 'SELECT array_resize(make_array(1), 9223372036854775807, 0)'`
DataFusion CLI v54.0.0
Error: Execution error: array_resize: resulting array of 9223372036854775807 elements exceeds the maximum array size
```

Subject: [PATCH 432/878] fix: cardinality returns incorrect results for ragged
 nested arrays (#23271)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23270.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`cardinality` used `compute_array_dims` and multiplied the inferred
dimensions to compute nested array cardinality. That only works for
rectangular nested arrays, where every nested list has the same shape.

For ragged nested arrays, `compute_array_dims` follows the first nested
value shape and can return dimensions that do not describe the actual
number of leaf elements. As a result, `cardinality` can return incorrect
results for valid nested arrays.

Examples:

```sql
select cardinality([[1], [2, 3]]);
-- before: 2
-- after:  3

select cardinality([[1, 2, 3], []]);
-- before: 6
-- after:  3

select cardinality([[], [1, 2]]);
-- before: 0
-- after:  2
```

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

This PR changes list cardinality computation to recursively count actual
leaf elements instead of multiplying inferred dimensions.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes, added sqllogictest coverage.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Bug fix only.

## Additional discussion

The root cause is that `cardinality()` used `compute_array_dims()` and
multiplies the returned dimensions.

`compute_array_dims()` itself follows the first child array when
computing nested dimensions. This behavior may also need a separate
discussion for ragged nested arrays, because such arrays do not have a
single rectangular dimension vector. For example, `array_dims([[1], [2,
3]])` currently returns `[2, 1]`.

Subject: [PATCH 433/878] test: Add coverage for `NOT IN`  predicates (#23378)

## Which issue does this PR close?

- related to https://github.com/apache/datafusion/issues/23307

## Rationale for this change

As @geoffreyclaude adds additional special implementations for IN lists
we should keep up with slt test coverage. The nullable integer coverage
already exercises `IN` with and without NULL list values; this adds the
corresponding negated `NOT IN` coverage.

## What changes are included in this PR?

This adds basic sqllogictest coverage for `NOT IN` predicates in
`in_list.slt`, covering each specialized integer type in the nullable IN
list table with and without NULL list values.

## Are these changes tested?

Tested by CI.

## Are there any user-facing changes?

No. This only adds test coverage.

Subject: [PATCH 436/878] Fix:22477 any all schema error (#22915)

## Which issue does this PR close?

- Closes #22477.

## Rationale for this change

`= ANY (SELECT ...)` and `<> ALL (SELECT ...)` decorrelate into stacked
mark joins. The optimizer was pruning each mark join's right child to
zero columns, which dropped its table reference. Without a qualifier,
every mark column came out named just `mark`, resulting in the schema
error.

## What changes are included in this PR?

Mark joins now keep one column from the right child instead of pruning
it down to nothing. The right child holds onto its table reference, the
mark now stays qualified.

## Are these changes tested?

A unit test builds three stacked mark joins and checks the plan
optimizes without the schema error. An sqllogictest runs `= ANY` and `<>
ALL` end-to-end against a small table.

## Are there any user-facing changes?

No.

Subject: [PATCH 437/878] [codex] chore: update Rust toolchain to 1.96.1
 (#23379)

## Which issue does this PR close?

- Closes #.

## Rationale for this change

DataFusion generally uses the latest stable Rust release for the
workspace toolchain. `rustup check` reports an available stable update
from `1.96.0` to `1.96.1`.

## What changes are included in this PR?

- Updates the root `rust-toolchain.toml` channel from `1.96.0` to
`1.96.1`.
- Updates the contributor guide rust-analyzer command example to match
the pinned toolchain.

## Are there any user-facing changes?

No runtime or API changes. Developers and CI will use Rust `1.96.1` as
the pinned workspace toolchain.

 avoid materializing low-cardinality columns (#22905)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Related to #19458
- Related to #20935

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

When a `Dictionary(K, Utf8)` column is passed to a string scalar
function, the type-coercion layer currently materializes it to flat
Utf8/Utf8View before the function runs, so the operation is applied to
every row instead of just the unique dictionary values, and the
dictionary encoding is lost on the output. See #19458 for the underlying
coercion behavior and #20935 for the string-function-specific impact.

This is wasteful for low-cardinality columns and inflates Arrow
IPC/Flight message sizes downstream.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add `EncodingPreservation { None, Dictionary }` and opt-in
constructors on `Coercion` (`new_exact_preserving_encoding`,
`with_encoding_preservation`).
- In `get_valid_types`, when a `Coercible` arg requests `Dictionary`
preservation, run coercion against the dictionary's value type and
re-wrap the result as `Dictionary(K, V')`, so the function receives a
`DictionaryArray`.
- Make `lower/upper` opt in and handle dictionary inputs (array +
scalar) by converting only the dictionary values and re-wrapping with
the original keys.

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

Yes. upper/lower now return Dictionary(...) for dictionary inputs
instead of the previously materialized Utf8View. New public API
(EncodingPreservation, new Coercion constructors) is added — please add
the api change label.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 440/878] feat: physical execution for range partitioning
 (#23231)

## Which issue does this PR close?

- Closes #23137

## Rationale for this change

Range repartitioning was already planned and serialized into physical
plans, but `RepartitionExec` could not execute it. This PR completes the
core execution path so rows in an input batch are routed to the correct
output partition based on range split points and the ordering defined on
the partitioning scheme.

## What changes are included in this PR?

This PR adds a `Range` variant to `BatchPartitioner` that evaluates the
ordering expressions on each input batch, compares each row's key
against split points using `compare_rows` (respecting ASC/DESC and null
ordering), and assigns row indices to output partitions via binary
search. The partitioned row indices are then materialized into
sub-batches using the same `partition_grouped_take` path as hash
repartitioning. `pull_from_input` is wired to construct a range
partitioner for `Partitioning::Range`, replacing the previous
`not_impl_err!` at execution time.

Optimizer-related paths remain intentionally unimplemented and are
tracked in [#23230](https://github.com/apache/datafusion/issues/23230):
projection pushdown through `RepartitionExec`
(`try_swapping_with_projection`), sort pushdown (`try_pushdown_sort`),
and changing partition counts via `repartitioned()`.

## Are these changes tested?

Yes!

## Are there any user-facing changes?

No public API changes

Subject: [PATCH 441/878] Push sort requirements through simple projections
 (#23288)

Allow `EnforceSorting` sort pushdown to remap ordering requirements
through `ProjectionExec` when the required output columns are simple
aliases or reordered input columns.

## Which issue does this PR close?

Prior this patch sort pushdown stopped at `ProjectionExec`, even when
the projection only changed column order. This could force a `SortExec`
above the projection and therefore above larger subplans such as
`UnionExec`, preventing branch-local sorts from being used.

The new logic conservatively handles only column-to-column projections
and leaves computed expressions untouched, preserving correctness while
enabling better plans for reordered projection cases.

- Closes #.

## Are these changes tested?

Yes:

* new test `test_push_sort_through_reordered_projection_to_union` added.
* Existing tests are updated accordingly.

## Are there any user-facing changes?

No

Subject: [PATCH 442/878] refactor(hash-aggr): Simplify aggregate hash table
 with tempated functions (#23324)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of https://github.com/apache/datafusion/issues/22710

- An alternative for and closes
https://github.com/apache/datafusion/pull/23309


## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
See #23309 and
https://github.com/apache/datafusion/pull/23309#discussion_r3522932671
for background.

I prefer this approach, but I want to point out the tradeoff for this
PR's approach: the shared utility includes a complex lambda function
argument, this makes them harder to extend. But I think it's okay since
most functionality has been implemented for the refactor, and there are
not likely to have new functional requirements.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 443/878] refactor: centralizing shared-allocation accounting
 for Arc DFHeapSize impls (#23349)

## Which issue does this PR close?

- Closes #22867

## Rationale for this change

DFHeapSize depends on a critical invariant: shared heap allocations must
be counted once per traversal context. If Arc implementations drift,
memory accounting becomes inconsistent and hard to reason about.

Consolidating the one-time-accounting logic improves:

Correctness durability (single source of truth for Arc dedup behavior)
Maintainability (less repeated logic)
Reviewability (future changes touch one helper)

## What changes are included in this PR?

Helper functions for `Arc` allocation identity and deduplication, namely
for providing pointer extraction & `DFHeapSizeCtx` set membership
checks, with the `DFHeapSize` implementations on `Arc` backed types
using the new helpers

## Are these changes tested?
Yes, the below are passing:
```
cargo test -p datafusion-common heap_size --lib
cargo test -p datafusion-common --doc heap_size
```

## Are there any user-facing changes?

No

Subject: [PATCH 444/878] Fix union equivalence schema rewrite with stale
 constants (#23375)

## Which issue does this PR close?

- Closes #23374.

## Rationale for this change

`UnionExec::try_new` can panic while computing equivalence properties if
stale constant metadata is carried across a projection and then
rewritten to the union output schema.

In the observed shape, a filter such as `ticker = 'ESU6'` can leave a
uniform string constant in equivalence properties. After a parent
projection drops `ticker`, union property schema rewriting can see the
remaining column slot as a timestamp column and attempt to cast `'ESU6'`
to `Timestamp`, which fails during planning.

Equivalence constants are optimizer metadata, so an unrepresentable
constant after schema rewrite should be discarded rather than failing
query planning.

## What changes are included in this PR?

- Drops a uniform constant during
`EquivalenceProperties::with_new_schema` if its value cannot be cast to
the rewritten expression type.
- Removes trivial equivalence classes after dropping such constants.
- Propagates `UnionExec::compute_properties` errors from
`UnionExec::try_new` instead of unwrapping.
- Adds a regression test for union equivalence schema rewrite with an
unrepresentable stale constant value.

## Are these changes tested?

Yes:


## Are there any user-facing changes?

No API change. This prevents a planner panic for affected `UNION ALL` +
filter + projection query shapes.

Subject: [PATCH 445/878] feat: Support FixedSizedBinary type for
 approx_distinct (#23417)

## Which issue does this PR close?

- Relates to https://github.com/apache/datafusion/issues/22989 but does
not close it. More types are coming.


## Rationale for this change

- Support the `FixedSizedBinary` type for `approx_distinct`
- The Arrow type `FixedSizedBinary` can be directly supported for
`HLLAccumulator` and `HllGroupsAccumulator`

## What changes are included in this PR?

- Enable `HLLAccumulator` and `HllGroupsAccumulator` to support
`FixedSizedBinary`
- Tests for the non-grouped and grouped path as part of `aggregate.slt`

## Are these changes tested?

Yes

## Are there any user-facing changes?

Yes, `approx_distinct` supports now `FixedSizedBinary` but no breaking
changes.

Subject: [PATCH 447/878] Fix memory size accounting for grouped `median` and
 `avg` (#23357)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`AvgGroupsAccumulator` stores sums in `Vec<T::Native>`, and
`MedianGroupsAccumulator` stores grouped values in
`Vec<Vec<T::Native>>`, but their `size()` implementations used
`size_of::<T>()` when accounting for those allocations.

This underreports memory usage for those grouped aggregate buffers.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Use `size_of::<T::Native>()` for grouped `avg` sum storage.
- Use `size_of::<T::Native>()` for grouped `median` value storage.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Existing aggregate tests pass.

## Are there any user-facing changes?

No. This only affects internal memory accounting.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 449/878] refactor: extract parquet projection read plan into
 its own module (#23396)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- N/A — pure code movement, split out of a larger change (see
rationale). First of a 3-PR stack: this refactor, #23397 (benchmark),
and the feature PR (nested schema pruning for the parquet reader,
upstream work for apache/datafusion-comet#4859).

## Rationale for this change

`row_filter.rs` is 2,100+ lines and contains two distinct concerns:
row-filter/`ArrowPredicate` construction, and the shared "expressions →
parquet leaf indices → `ProjectionMask` + projected schema" resolution
used by both the row filter and the opener's projection handling. This
PR moves the second concern into its own module,
`projection_read_plan.rs`, so upcoming changes to projection-mask
derivation can be reviewed without wading through the row-filter
machinery.

This is mergeable as standalone cleanup regardless of whether the
follow-up feature is accepted.

## What changes are included in this PR?

A move-only refactor (best reviewed with `git diff --color-moved`):

- `ParquetReadPlan`, `StructFieldAccess`, `build_projection_read_plan`,
`leaf_indices_for_roots`, `resolve_struct_field_leaves`,
`build_filter_schema`, `prune_struct_type` and the path-grouping helpers
move from `row_filter.rs` to a new `projection_read_plan.rs`, together
with their test.
- `PushdownChecker` / `PushdownColumns` become `pub(crate)` so the new
module can keep using them.
- `decoder_projection.rs` imports `build_projection_read_plan` from its
new home.

No behavior change; net +57 lines (module docs, imports, visibility).

## Are these changes tested?

Covered by existing tests (the moved unit test plus the
`datafusion-datasource-parquet` and core parquet integration suites,
which all pass unchanged).

## Are there any user-facing changes?

No.

+//! Resolution of expressions against a Parquet file's schema into a
+//! [`ParquetReadPlan`]: the leaf-level [`ProjectionMask`] to install on the
+//! decoder plus the Arrow schema the decoder will emit under that mask.
+//!
+//! This is shared by the opener's projection handling (via
+//! [`build_projection_read_plan`]) and row-filter construction (via
+//! [`crate::row_filter`]), which both need to translate column and struct
+//! field references into Parquet leaf indices. [`PushdownChecker`], the
+//! expression traversal that discovers those references, lives here as well
+//! so that [`crate::row_filter`] depends on this module and not vice versa.

Subject: [PATCH 450/878] Remove unstable public methods for
 `DynamicFilterPhysicalExpr` after proto migration (#23423)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes https://github.com/apache/datafusion/issues/23422
- Closes https://github.com/apache/datafusion/issues/22434

## Rationale for this change

See https://github.com/apache/datafusion/issues/22418. After migrating
`DynamicFilterPhysicalExpr` serialization from relying on leaking public
internals, we can now remove these unstable methods because they aren't
used outside the package.

```
pub struct Inner {
...
}

/// Return the filter's original children (before any remapping).
///
/// **Warning:** intended only for `datafusion-proto` (de)serialization.
/// Not a stable API.
pub fn original_children(&self) -> &[Arc<dyn PhysicalExpr>] {
    &self.children
}

/// Return the filter's remapped children, if any have been set via
/// [`PhysicalExpr::with_new_children`].
///
/// **Warning:** intended only for `datafusion-proto` (de)serialization.
/// Not a stable API.
pub fn remapped_children(&self) -> Option<&[Arc<dyn PhysicalExpr>]> {
    self.remapped_children.as_deref()
}
```

## What changes are included in this PR?

See above.

## Are these changes tested?

- Existing unit tests are migrated to private accessors
- There's no usage of these methods out side of
`datafusion/physical-expr/src/expressions/dynamic_filters`

## Are there any user-facing changes?

Unstable public methods and public types for `DynamicFilterPhysicalExpr`
are private now.

Subject: [PATCH 451/878]  Perf: Add short circuit for primitive vectorized
 equal_to (#23343)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- works towards #23342.

## Rationale for this change
other `groupColumn` traits follow the pattern of short circuiting the
equal_to comparison if a previous `groupColumn` set that bit to zero.
This is because all traits needs to assert that the value is the same
for each row, otherwise its a new tuple. This avoids an un-needed
(potentially expensive) comparison.
<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?
adds an early check to read the bit at the current index.
<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?
yes
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?
no
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 452/878] refactor: centralize date_bin per-row mapping
 (#23034)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22987.

## Rationale for this change

`date_bin` had duplicated scalar and array per-row logic. This made
timestamp scaling, TIME wrapping, and per-row error handling easier to
diverge.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

  - Adds shared helpers for timestamp and TIME per-row binning.
- Routes scalar and array timestamp/TIME paths through the shared
helpers.
  - Extracts shared month shifting logic.
  - Hoists the TIME source/origin guard out of each TIME branch.
  - Adds scalar/array parity tests and TIME origin guard coverage.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23099 .

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`FileScanConfig` had two overlapping ways to declare a file scan's
output
partitioning:

- `partitioned_by_file_group: bool` — a shorthand meaning "the file
groups are
organized by Hive partition column values, so the output is
Hash-partitioned on
  those columns", and
- `output_partitioning: Option<Partitioning>` — a general, explicit
declared
  partitioning (added in #22657).

The bool is just a lazy shorthand for one specific `output_partitioning`
value
(`Partitioning::Hash` over the partition columns), and every place that
consumed
it (`output_partitioning()`, `repartitioned()`,
`create_sibling_state()`) already
checked `output_partitioning.is_some() || partitioned_by_file_group`.
Keeping both
is redundant and the `ListingTable` builder ended up setting *both*.
This PR makes
`output_partitioning` the single source of truth.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Following the issue's first option ("Remove
`partitioned_by_file_group`"):

- Remove `FileScanConfig::partitioned_by_file_group`, the corresponding
`FileScanConfigBuilder` field, and the `with_partitioned_by_file_group`
builder
  method.
- `ListingTable::scan` now derives the partition-column
`Partitioning::Hash`
itself (once its file groups are finalized, so the partition count is
correct)
and passes it through the existing `with_output_partitioning`. The
previous
`with_output_partitioning(declared)` +
`with_partitioned_by_file_group(...)`
  double-set is collapsed into one branch.
- `hash_partitioning_from_partition_fields` is made `pub` so
`ListingTable`
  (a separate crate) can reuse the derivation instead of duplicating the
  column-index resolution.
- proto already round-trips `output_partitioning`, so no behavior is
lost: the
now-vestigial `partitioned_by_file_group` wire field is left unset on
write and
ignored on read. The field is kept in the `.proto` definition for
backward
  compatibility.
- `output_partitioning()` / `create_sibling_state()` / `repartitioned()`
now key
  solely off `output_partitioning`.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes — by existing tests, updated to the new single-field model:

- `datafusion-datasource`:
`test_output_partitioning_with_partition_columns`,
  `test_output_partitioning_no_partition_columns`,
`test_declared_output_partitioning_projects_with_scan`, and the
`file_stream`
work-stealing test `morsel_partitioned_by_file_group_keeps_files_local`
(which
verifies that a declared output partitioning keeps each stream's files
local).
- `datafusion-proto`: `roundtrip_parquet_exec_output_partitioning` (and
the other
`roundtrip_parquet_exec_*` cases) cover the partitioning round-trip. The
old
`roundtrip_parquet_exec_partitioned_by_file_group` test exercised the
removed
API and is dropped, as its coverage is subsumed by the
`output_partitioning`
  round-trip test.

All of the above pass, along with `cargo fmt --all --check` and
`cargo clippy --all-targets --all-features -- -D warnings` for the
affected
crates.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Yes — public API changes :

- Removed: the public `FileScanConfig::partitioned_by_file_group` field
and the
`FileScanConfigBuilder::with_partitioned_by_file_group` method. Callers
should
set `with_output_partitioning(Some(Partitioning::Hash(..)))` instead (or
use the
  now-public `hash_partitioning_from_partition_fields` helper).
- Added: `hash_partitioning_from_partition_fields` is now `pub`.

Query results, optimizer decisions (e.g. eliding `RepartitionExec`), and
the
serialized (proto) wire format are unchanged. There is one
**display-only**
change: EXPLAIN now renders `output_partitioning=Hash(...)` on
`DataSourceExec`
for partition-grouped scans. The scan already produced that partitioning
before
(it was derived lazily inside `output_partitioning()`); it is now stored
on the
`output_partitioning` field and therefore shown. The
`repartition_subset_satisfaction` and `preserve_file_partitioning` slt
expected
plans are updated accordingly.

`cargo-semver-checks` will flag the removals as breaking, which is
expected for
this cleanup.

 datafusion.optimizer.prefer_existing_sort false When true, DataFusion will opportunistically remove sorts when the data is already sorted, (i.e. setting `preserve_order` to true on `RepartitionExec`  and using `SortPreservingMergeExec`) When false, DataFusion will maximize plan parallelism using `RepartitionExec` even if this requires subsequently resorting data using a `SortExec`.
 datafusion.optimizer.prefer_existing_union false When set to true, the optimizer will not attempt to convert Union to Interleave

This threshold preserves I/O parallelism when file partitioning is below it. Note: This may reduce parallelism, rooting from the I/O level, if the number of distinct partitions is less than the target_partitions.
 datafusion.optimizer.repartition_aggregations true Should DataFusion repartition data using the aggregate keys to execute aggregates in parallel using the provided `target_partitions` level
 datafusion.optimizer.repartition_file_min_size 1048576 Minimum total file size in bytes for file-group byte-range splitting to fire. Files (or merged file groups) smaller than this stay as one partition. Lower values produce more, smaller partitions — better at filling `target_partitions` worth of cores when files are modestly sized, at the cost of slightly more per-partition open / metadata-load overhead.
 datafusion.optimizer.repartition_file_scans true When set to `true`, datasource partitions will be repartitioned to achieve maximum parallelism. This applies to both in-memory partitions and FileSource's file groups (1 group is 1 partition). For FileSources, only Parquet and CSV formats are currently supported. If set to `true` for a FileSource, all files will be repartitioned evenly (i.e., a single large file might be partitioned into smaller chunks) for parallel scanning. If set to `false` for a FileSource, different files will be read in parallel, but repartitioning won't happen within a single file. If set to `true` for an in-memory source, all memtable's partitions will have their batches repartitioned evenly to the desired number of `target_partitions`. Repartitioning can change the total number of partitions and batches per partition, but does not slice the initial record tables provided to the MemTable on creation.

+### `FileScanConfig::partitioned_by_file_group` removed
+
+`FileScanConfig::partitioned_by_file_group` and
+`FileScanConfigBuilder::with_partitioned_by_file_group(...)` have been removed.
+Use `FileScanConfig::output_partitioning` and
+`FileScanConfigBuilder::with_output_partitioning(...)` instead.
+
+**Who is affected:**
+
+- Users who accessed `FileScanConfig::partitioned_by_file_group` directly.
+- Users who called
+  `FileScanConfigBuilder::with_partitioned_by_file_group(true)`.
+
+**Migration guide:**
+
+If your file groups are organized by table partition column values, declare hash
+output partitioning over those partition columns:
+
+```rust,ignore
+use datafusion_datasource::file_scan_config::{
+    FileScanConfigBuilder, output_partitioning_from_partition_fields,
+};
+
+let output_partitioning = output_partitioning_from_partition_fields(
+    source.table_schema().table_schema(),
+    source.table_schema().table_partition_cols(),
+    file_groups.len(),
+);
+
+let config = FileScanConfigBuilder::new(object_store_url, source)
+    .with_file_groups(file_groups)
+    .with_output_partitioning(output_partitioning)
+    .build();
+```
+
+`output_partitioning_from_partition_fields` returns
+`Some(Partitioning::Hash(...))` when partition columns are present and `None`
+otherwise. If you construct the partitioning manually, pass
+`Some(Partitioning::Hash(partition_exprs, partition_count))` to
+`with_output_partitioning(...)`.
+

This applies to both in-memory partitions and FileSource's file groups (1 group is 1 partition). For FileSources, only Parquet and CSV formats are currently supported. If set to `true` for a FileSource, all files will be repartitioned evenly (i.e., a single large file might be partitioned into smaller chunks) for parallel scanning. If set to `false` for a FileSource, different files will be read in parallel, but repartitioning won't happen within a single file. If set to `true` for an in-memory source, all memtable's partitions will have their batches repartitioned evenly to the desired number of `target_partitions`. Repartitioning can change the total number of partitions and batches per partition, but does not slice the initial record tables provided to the MemTable on creation.                                                                                                                                                                                                                                                                                                                      |

When the current partition count is >= this threshold, DataFusion will skip repartitioning if the required partitioning expression is a subset of the current partition expression such as Hash(a) satisfies Hash(a, b). When the current partition count is < this threshold, DataFusion will repartition to increase parallelism even when subset satisfaction applies. Set to 0 to always repartition (disable subset satisfaction optimization). Set to a high value to always use subset satisfaction. Example (subset_repartition_threshold = 4): `text Hash([a]) satisfies Hash([a, b]) because (Hash([a, b]) is subset of Hash([a]) If current partitions (3) < threshold (4), repartition: AggregateExec: mode=FinalPartitioned, gby=[a, b], aggr=[SUM(x)] RepartitionExec: partitioning=Hash([a, b], 8), input_partitions=3 AggregateExec: mode=Partial, gby=[a, b], aggr=[SUM(x)] DataSourceExec: file_groups={...}, output_partitioning=Hash([a], 3) If current partitions (8) >= threshold (4), use subset satisfaction: AggregateExec: mode=SinglePartitioned, gby=[a, b], aggr=[SUM(x)] DataSourceExec: file_groups={...}, output_partitioning=Hash([a], 8) ` |

Subject: [PATCH 455/878] bench: add date_part benchmark (#23350)

## Which issue does this PR close?

- Refers #23351

## Rationale for this change

`date_part` UDF and other datetime functions have non-trivial logic and
should be benchmarked

## What changes are included in this PR?

Brand new bench for `date_part`. Covers a lot of code paths and input
combinations

## Are these changes tested?

I've run it locally; it passes.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 456/878] Update Rust toolchain to 1.97.0 (#23430)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example

-->

- Closes https://github.com/apache/datafusion/issues/23431

## Rationale for this change

Bump the pinned Rust toolchain from 1.96.1 to 1.97.0 and fix the new
Clippy lints introduced in this release (useless_borrows_in_formatting,
question_mark, manual match-to-`?` rewrites, and uninlined_format_args).

## What changes are included in this PR?

Bump the pinned Rust toolchain from 1.96.1 to 1.97.0

## Are these changes tested?


## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

Subject: [PATCH 457/878] refactor: de-duplicate parquet read plan construction
 (#23426)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- N/A — follow-up cleanup requested in review of #23396, in two
comments:
[`root_level_plan`](https://github.com/apache/datafusion/pull/23396#discussion_r3552883479)
and
[`assemble_read_plan`](https://github.com/apache/datafusion/pull/23396#discussion_r3552881821).

Two independent commits, each green on its own; best reviewed commit by
commit.

## Rationale for this change

@mbutrovich spotted two pieces of duplication in
`projection_read_plan.rs` while reviewing #23396, both deferred out of
that (move-only) PR:

1. `build_projection_read_plan` has three early-return paths — the
all-plain-columns fast path, the no-struct-columns fast path, and the
no-struct-accesses fallback. Each repeated the same
`ProjectionMask::roots` + `Schema::project` +
construct-`ParquetReadPlan` sequence.

2. `build_projection_read_plan` and
`row_filter::build_parquet_read_plan` both end in the same chain to
build a leaf-level plan:

   ```
leaf_indices_for_roots → resolve_struct_field_leaves → extend/sort/dedup
       → ProjectionMask::leaves → build_filter_schema → ParquetReadPlan
   ```

They differ only in that the row filter also sizes the resulting leaves
(`required_bytes`) and returns an `Option`.

## What changes are included in this PR?

**Commit 1 — `root_level_plan`:** a new private helper taking sorted,
deduplicated root indices and decoding every leaf below each root. The
three early-return paths delegate to it. Net −9 lines.

**Commit 2 — `assemble_read_plan`:** shared by both callers. It returns
the `ParquetReadPlan` plus the resolved leaf indices, which is what lets
the row filter keep computing `required_bytes` without duplicating leaf
resolution. `build_parquet_read_plan` shrinks from ~30 lines to ~10.
`leaf_indices_for_roots`, `resolve_struct_field_leaves` and
`build_filter_schema` become private to `projection_read_plan`, since
`assemble_read_plan` is now their only caller.

No behavior change in either commit.

## Are these changes tested?

Yes, by existing tests: `datafusion-datasource-parquet` unit tests (158
pass) and the `parquet_integration` suite in `datafusion` (213 pass),
both unchanged and both green at each commit. The row-filter path
touched by commit 2 is covered by `parquet::filter_pushdown` and the
struct-field pushdown tests in `row_filter.rs`.

## Are there any user-facing changes?

No.

Subject: [PATCH 459/878] fix: don't duplicate volatile expressions when
 pushing projection into file scan (#23395)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23220.

## Rationale for this change

The reported bug showed that when volatile (non-deterministic)
expressions are referenced multiple times in an outer function the query
results can be incorrect.

To produce correct results, a volatile expression (e.g. `random()`,
`uuid()`) aliased once in a subquery and referenced multiple times must
be evaluated once and reused. Since 52.0.0 this evaluation pattern for
volatile functions has been broken; the physical projection-pushdown
rule merges the outer projection into the file `DataSourceExec`,
inlining the aliased volatile expression at each reference site. Instead
of being evaluated once, the volatile expression is evaluated N times,
so the references diverge:

```sql
SELECT s.r AS x, s.r AS y FROM (SELECT random() AS r FROM t) AS s;  -- x != y on >= 52.0.0
```

This was correct in 51.0.0 and regressed in 52.0.0/53.0.0. It reproduces
on file scans (Parquet/CSV) but not in-memory tables, and was surfaced
downstream in Ibis. Worth noting, #10337 appears to report the same
class of bug but a different cause (I'll try to look into that issue
soon as well).

## What changes are included in this PR?

`FileScanConfig::try_swapping_with_projection` now declines to merge a
projection into the file source when the merge would inline a volatile
expression that the incoming projection references. The check reuses the
existing `is_volatile()` utility from `datafusion_physical_expr_common`
— the same volatility gate the physical `ProjectionPushdown` and
`FilterPushdown` rules already apply — so file-source projection merging
is now consistent with them. Deterministic expressions still merge
freely.

The guard blocks when a volatile inner expression is referenced at least
once (not only more than once), because a single outer expression can
itself duplicate the value (e.g.`r + r`).

## Are these changes tested?

Yes:
- Unit tests in `file_scan_config.rs`:
    - volatile referenced ≥1× → blocked;
    - deterministic computed and column-only → allowed;
    - unreferenced volatile → allowed;
    - single-expression self-reference (`r + r`) → blocked;
    - volatile nested in arithmetic → blocked;
    - empty → allowed.
- A regression test in `projection_pushdown.slt` asserting `x = y` for
the aliased-`random()` pattern over a Parquet scan.
- Full `datafusion-sqllogictest` suite passes.

## Are there any user-facing changes?

No API changes! Query results for the affected pattern are corrected (a
volatile expression aliased in a subquery is no longer duplicated by
projection pushdown into a file scan). Physical plans for such queries
now retain a `ProjectionExec` above the scan rather than inlining the
volatile expression into the `DataSourceExec` projection.

Subject: [PATCH 460/878] Use `concat_elements_dyn` from `arrow-rs` (#23211)

## Which issue does this PR close?

- Closes #23210

## Rationale for this change

https://github.com/apache/arrow-rs/pull/9876 added `ByteView` and
`FixedSizeBinary` support to `concat_elements_dyn` in `arrow-rs`. As a
consequence the extended implementation in DataFusion can now be
replaced by a call to the `arrow-rs` implementation.

## What changes are included in this PR?

- Remove the `kernels::concat_elements_utf8view` and
`kernels::concat_elements_binary_view_array`
- Replace implementation of `binary::concat_elements` with a call to
`arrow::compute::kernels::concat_elements::concat_elements_dyn`

## Are these changes tested?

- Usage is covered by existing tests
- The kernels themselves are tested in `arrow-rs`

## Are there any user-facing changes?

No, two `pub` functions have been removed from `kernel`, but `kernel`
itself is not `pub`.

Subject: [PATCH 461/878] Add protobuf support for lambdas (#22362)

## Which issue does this PR close?

Part of #21172

## Rationale for this change

Protobuf support wasn't implemented in main lambda PR to not make it
even bigger

## What changes are included in this PR?

Protobuf encoding and decoding (~1000 LOC in generated files, ~210 impl,
~400 tests)

## Are these changes tested?

Unit tests, similar to the existing ones for scalar functions

## Are there any user-facing changes?

Proto `ExprType` has new variants

Subject: [PATCH 462/878] perf(physical-plan): fold PlanProperties fast-path
 into with_new_children_if_necessary (PR 1 of #22555) (#23332)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Part of #22555. This is **PR 1 of 2** — see the issue body for the full
plan. PR 2 will audit direct `with_new_children` callers and add a
clippy lint.

## Rationale for this change

Today the "skip work when children are unchanged" intent is split across
two layers:

- **caller-side** —
[`with_new_children_if_necessary`](https://github.com/apache/datafusion/blob/main/datafusion/physical-plan/src/execution_plan.rs)
short-circuits via `Arc::ptr_eq` on child pointers.
- **callee-side** — the `check_if_same_properties!` macro from #19792,
invoked inside each impl's `with_new_children`, short-circuits when
children's `PlanProperties` Arcs match (allowing the plan to reuse its
cached `PlanProperties` Arc instead of recomputing).

Having two independent layers means two places to maintain and two
places for future changes to drift apart. This PR consolidates the
fast-path into the single free-function helper so callers get both
short-circuits uniformly.

## What changes are included in this PR?

`with_new_children_if_necessary` now applies **three layers**, cheapest
first:

1. **Same child pointers** — every `children[i]` is `Arc::ptr_eq` to the
corresponding existing child → return the original plan unchanged, no
allocation.
2. **Same child properties** — children's `PlanProperties` Arcs match →
call the new [`ExecutionPlan::with_new_children_and_same_properties`](#)
trait method to reuse the plan's `PlanProperties` cache without
recomputing.
3. **Full recompute** — otherwise, delegate to
`ExecutionPlan::with_new_children`.

To make layer 2 dispatchable via `&dyn ExecutionPlan`,
`with_new_children_and_same_properties` is promoted from an ad-hoc
inherent method on each impl to a **trait method** with a safe default
that falls back to `with_new_children`. All 22 existing impls migrate
their inherent method to a trait override (mechanical change — signature
`&self → self: Arc<Self>`, return `Self → Result<Arc<dyn
ExecutionPlan>>`, body wrapped in `Ok(Arc::new(...))`).

The `check_if_same_properties!` macro and its call sites inside impls
are **kept**, so direct callers of `with_new_children` (which PR 2 will
audit + migrate) do not regress on this PR.

## Are these changes tested?

Yes — added `test_with_new_children_if_necessary_layers` in
`execution_plan.rs` that constructs test-local `WithChildrenTestLeaf` +
`WithChildrenTestParent` plans (the parent tracks recompute vs fast-path
calls via `AtomicUsize`) and asserts, for each of the three layers:

- **Layer 1**: `Arc::ptr_eq(result, parent)` returns true,
`recompute_calls == 0`, `fast_path_calls == 0`
- **Layer 2**: `Arc::ptr_eq(result.properties(), orig_props)` returns
true, `recompute_calls == 0`, `fast_path_calls == 1`
- **Layer 3**: `Arc::ptr_eq(result.properties(), orig_props)` returns
false, `recompute_calls == 1`, `fast_path_calls` unchanged

All 1523 `datafusion-physical-plan` unit tests pass. Full workspace
`cargo check` + `cargo clippy --all-targets --all-features -- -D
warnings` pass.

## Are there any user-facing changes?

Yes — `ExecutionPlan` gains a new default-implemented trait method
`with_new_children_and_same_properties`. Downstream impls that used to
override the ad-hoc inherent method with the same name will need to
re-implement as a trait override (mechanical signature change). Marking
as `api change`.

## Follow-up (PR 2, not in this PR)

- Audit the ~47 remaining direct callers of
`plan.with_new_children(children)` across the codebase and route them
through `with_new_children_if_necessary`.
- Add a `disallowed_methods` clippy lint (or custom lint) that forbids
direct `ExecutionPlan::with_new_children` outside of a small allow-list.
- Once all callers migrate, remove the `check_if_same_properties!` macro
and its impl-side invocations, making the helper the single source of
truth as described in the issue.

Subject: [PATCH 463/878] Support co-partitioned range inner equi joins
 (#23184)

## Which issue does this PR close?

- Closes #23183.
- Part of #22395.

## Rationale for this change

DataFusion can represent source-declared range partitioning, but
partitioned hash joins still required hash partitioned inputs. So an
inner join on compatible range-partitioned keys would insert unnecessary
hash repartitions, even when each left/right partition already covered
the same key domain.

This PR adds a partitioning requirement that means "equal key values are
co-located" . I was calling this "compatibility" but found we can
satisfy the requirement with looser conditions. Other systems call this
"co-location" or "co-partitioning"
([trino](https://trino.io/docs/current/admin/properties-optimizer.html#optimizer-colocated-joins-enabled),
[spark](https://spark.apache.org/docs/latest/sql-performance-tuning.html#storage-partition-join)).
Which they (and now I am proposing) define as when both sides of a join
are already partitioned so matching key values appear in corresponding
partitions, so we can join partition pairs directly without
repartitioning the sides.

This lets "co-partitioned" range inputs satisfy inner partitioned hash
joins. This will also be applicable to other join types and operators
but kept the first PR thin to keep scope more reviewable.

## What changes are included in this PR?

- Adds `Distribution::KeyPartitioned(Vec<Arc<dyn PhysicalExpr>>)` as a
public distribution requirement.
- `HashPartitioned([a])` means rows must be partitioned by hash on `a`.
- `KeyPartitioned([a])` means rows with equal `a` values must be
co-located, but the partitioning algorithm may be hash, range, or
another compatible scheme.
  - Example:
    ```text
    Hash([left.a], 3) satisfies KeyPartitioned([left.a])
Range([right.b ASC], [(10), (20)], 3) satisfies
KeyPartitioned([right.b])
    ```

- Adds `Partitioning::co_partitioned_with(...)` to validate that two
independently satisfying partitionings also can be paired by partition
index.
  - Examples:
- Accepted: both sides satisfy their own key requirement and have
matching range boundaries.
      ```text
left: Range([a ASC], [(10), (20)], 3), required KeyPartitioned([a])
right: Range([b ASC], [(10), (20)], 3), required KeyPartitioned([b])
      ```
- Accepted: both sides satisfy their own key requirement and have
matching hash partition counts.
      ```text
      left:  Hash([a], 3), required KeyPartitioned([a])
      right: Hash([b], 3), required KeyPartitioned([b])
      ```
- Rejected: both sides satisfy their own key requirement, but range
boundaries differ.
      ```text
left: Range([a ASC], [(10), (20)], 3), required KeyPartitioned([a])
right: Range([b ASC], [(15), (20)], 3), required KeyPartitioned([b])
      ```
- Rejected: both sides satisfy their own key requirement, but partition
counts differ.
      ```text
      left:  Hash([a], 3), required KeyPartitioned([a])
      right: Hash([b], 4), required KeyPartitioned([b])
      ```

- Changes inner partitioned `HashJoinExec` requirements from
`HashPartitioned` to `KeyPartitioned`.
  - All other hash joins still require `HashPartitioned` for now.

- Updates `EnforceDistribution` so co-partitioned range inner joins
avoid repartitioning.
  - Examples:
- Compatible range partitioning: no repartition is inserted because
partitions can be joined by index.
      ```text
      HashJoinExec: mode=Partitioned, join_type=Inner, on=[(a, b)]
DataSourceExec: output_partitioning=Range([a ASC], [(10), (20)], 3)
DataSourceExec: output_partitioning=Range([b ASC], [(10), (20)], 3)
      ```
- Incompatible range boundaries: both sides are repartitioned by hash
because partition `i` does not represent the same key domain on both
sides.
      ```text
      HashJoinExec: mode=Partitioned, join_type=Inner, on=[(a, b)]
        RepartitionExec: partitioning=Hash([a], target_partitions)
DataSourceExec: output_partitioning=Range([a ASC], [(10), (20)], 3)
        RepartitionExec: partitioning=Hash([b], target_partitions)
DataSourceExec: output_partitioning=Range([b ASC], [(15), (20)], 3)
      ```
- Mismatched hash partition counts: both sides are forced to the target
hash partition count so partition indexes line up.
      ```text
      HashJoinExec: mode=Partitioned, join_type=Inner, on=[(a, b)]
        RepartitionExec: partitioning=Hash([a], target_partitions)
          DataSourceExec: output_partitioning=Hash([a], 11)
        RepartitionExec: partitioning=Hash([b], target_partitions)
          DataSourceExec: output_partitioning=Hash([b], 12)
      ```
- Non-inner joins: range inputs still get hash repartitioning because
only inner partitioned hash joins use `KeyPartitioned` in this PR.
      ```text
      HashJoinExec: mode=Partitioned, join_type=Left, on=[(a, b)]
        RepartitionExec: partitioning=Hash([a], target_partitions)
DataSourceExec: output_partitioning=Range([a ASC], [(10), (20)], 3)
        RepartitionExec: partitioning=Hash([b], target_partitions)
DataSourceExec: output_partitioning=Range([b ASC], [(10), (20)], 3)
      ```

- Keeps partitioned dynamic filter pushdown restricted to
hash-compatible routing.
- Compatible range partitioning can satisfy the join, but dynamic
filters still route by hash, so range/range partitioned joins disable
dynamic filters.

- Degrades range join output partitioning to `UnknownPartitioning(n)`
rather than erroring. Adding this behavior would need more tests and
careful thought about, I think its safert o just degrade for first PR.

## Are these changes tested?

Yes.

- `KeyPartitioned` satisfaction for hash and range partitioning.
- `co_partitioned_with` for compatible and incompatible range/hash
partitioning.
- `EnforceDistribution` behavior for:
  - compatible range joins avoiding hash repartitioning
  - incompatible range bounds rehashing
  - mismatched hash partition counts rehashing
  - non-inner range joins rehashing
- sanity checking for invalid partitioned hash joins.
- dynamic filter rejection for range partitioning, preserved file
partitions, and mismatched hash counts.
- sqllogictest coverage for range-partitioned joins avoiding hash
repartitioning and non-range joins still repartitioning.

## Are there any user-facing changes?

Yes.

This PR changes public physical planning APIs:

- Adds `Distribution::KeyPartitioned`.
- Adds `Partitioning::co_partitioned_with`.
- **NOTE**: This replaces the previous partition compatibility API with
the new co-partitioning API. Since the compatibility API was never in a
release I believe this is ok to do (lesson learned to not make API
change until ew have definitive consumer).

Subject: [PATCH 466/878] test: add Poll::Pending spill stream coverage for
 async spill re-entry paths (#23353)

## Which issue does this PR close?

- Closes #22879.

## Rationale for this change

The SortMergeJoin refactor in #22230 introduced async spill read paths
in both `materializing_stream.rs` (`poll_spilled_batches`) and
`bitwise_stream.rs` (the spilled-batch loop in
`process_key_match_with_filter`). Both call `SpillFile::read_stream()`
and poll the resulting byte stream, which can return `Poll::Pending`.

The existing spill tests exercise spilling and restoring batches, but
always run against the default local-file `SpillFile`, whose
`read_stream()` happens to resolve synchronously on first poll in
practice. As a result, the re-entry logic in both streams has no
dedicated test coverage.

## What changes are included in this PR?

- Adds a `PendingSpillFile` / `PendingTempFileFactory` pair in
`sort_merge_join/tests.rs` that wraps the default local `SpillFile`
backend (via `DiskManagerMode::Custom`). Every spill read splits the
real spill file's bytes into small fixed-size chunks and yields
`Poll::Pending` before each chunk, forcing `SpillReaderStream`'s IPC
decoder to genuinely suspend mid-read and resume from partially buffered
state across multiple real Pending cycles, rather than completing on the
first poll.
- Adds `materializing_spill_pending_stream`, covering Inner/Left/
Right/Full joins (the `BufferedBatchState::Spilled` restore path in
`poll_spilled_batches`).
- Adds `bitwise_spill_pending_stream`, covering LeftSemi/LeftAnti/
RightSemi/RightAnti joins with a filter (the `inner_key_spill` re-entry
path in `process_key_match_with_filter`).
- Both tests compare the Pending-forced spilled result against a
no-spill run of the same join, asserting the results are identical, so
any state corruption introduced by suspending mid-read would be caught.

## Are these changes tested?

Yes -- this is a PR to test recent changes

## Are there any user-facing changes?
No.

Subject: [PATCH 467/878] feat: Implement state conversion for remaining group
 accumulators (#23275)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of #23081.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

#23081 proposes making `GroupsAccumulator::convert_to_state` mandatory
and removing `supports_convert_to_state`.

Before that API cleanup can happen, all existing `GroupsAccumulator`
implementations need a correct `convert_to_state` implementation.

This PR is the first step toward that cleanup: it fills in missing
`convert_to_state` implementations for the remaining group accumulators
that currently participate in grouped aggregation.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

This PR adds `convert_to_state` support for:

- `PrimitiveDistinctCountGroupsAccumulator`
- `HllGroupsAccumulator` for `approx_distinct`
- `VarianceGroupsAccumulator`
- `StddevGroupsAccumulator`
- `CorrelationGroupsAccumulator`
- `GeometricMeanGroupsAccumulator` in the advanced UDAF example

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes. This PR adds unit tests for the new `convert_to_state`
implementations.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No. This PR does not remove `supports_convert_to_state` yet and does not
change the public `GroupsAccumulator` API.

Subject: [PATCH 468/878] perf: optimize encode in datafusion-functions
 (#23456)

## Which issue does this PR close?

N/A

## Rationale for this change

Rewrote the hex path of encode() to write hex directly into one
pre-sized buffer via hex::encode_to_slice, eliminating a per-element
String allocation and copy per row.

## Rationale for this change

Optimize existing expression.

## What changes are included in this PR?

Rewrote calculate_ascii to skip per-element null checks in the no-null
case, use value_unchecked to avoid bounds checks, and add an ASCII
leading-byte fast path that avoids char-iterator decoding for ASCII
strings.

## Are these changes tested?

Existing tests.

Subject: [PATCH 470/878] perf: optimize nanvl in datafusion-functions (#23458)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Improve performance of existing function.

## What changes are included in this PR?

Added a null-free fast path to the nanvl array kernel that iterates the
raw value slices (generic across `Float16`/`Float32`/`Float64`) instead
of per-element `Option` iteration plus collect, eliminating
null-bookkeeping overhead on the common no-null input.

## Are these changes tested?

Existing tests + one new unit test

Benchmark (criterion):

Wins:

- nanvl_array_f64_1024: 92.229% faster (base 3250ns -> cand 252ns)
- nanvl_array_f32_1024: 95.031% faster (base 3189ns -> cand 158ns)
- nanvl_array_f64_4096: 93.826% faster (base 12679ns -> cand 782ns)
- nanvl_array_f32_4096: 96.952% faster (base 12549ns -> cand 382ns)
- nanvl_array_f64_8192: 93.375% faster (base 25792ns -> cand 1708ns)
- nanvl_array_f32_8192: 96.997% faster (base 24943ns -> cand 749ns)

Within noise:

- nanvl_scalar_f64: -0.406% faster (base 36ns -> cand 36ns)
- nanvl_scalar_f32: -1.367% faster (base 36ns -> cand 37ns)


Partially-null inputs (base = `main`, cand = this PR). Even on inputs
containing nulls the rewritten kernel is faster than `main`:

- nanvl_array_f64_x_nulls_1024: 45.9% faster (base 3496ns -> cand
1893ns)
- nanvl_array_f64_y_nulls_1024: 39.2% faster (base 3300ns -> cand
2007ns)
- nanvl_array_f64_both_nulls_1024: 47.5% faster (base 3713ns -> cand
1949ns)
- nanvl_array_f64_x_nulls_4096: 41.5% faster (base 13360ns -> cand
7818ns)
- nanvl_array_f64_y_nulls_4096: 34.5% faster (base 12887ns -> cand
8439ns)
- nanvl_array_f64_both_nulls_4096: 46.0% faster (base 14506ns -> cand
7835ns)
- nanvl_array_f64_x_nulls_8192: 47.0% faster (base 27516ns -> cand
14582ns)
- nanvl_array_f64_y_nulls_8192: 42.1% faster (base 26585ns -> cand
15398ns)
- nanvl_array_f64_both_nulls_8192: 49.0% faster (base 29647ns -> cand
15119ns)

Also added benchmarks and unit tests for partially-null inputs
(only-x-null, only-y-null, both-null). Splitting the null-aware path
into per-configuration match arms was evaluated with these benchmarks
but regressed performance by 8-16% (the larger function body penalizes
even the unchanged both-null arm), so only the coverage additions were
kept.

Subject: [PATCH 471/878] Test: add more aggregation focused dictionary sql
 logic test (#23280)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

works towards #22682.

## Rationale for this change
There is a lack of testing for multi-dictionary group bys. It make sense
to introduce these test before the implementation of `Dict<K,V>` in
#23187
<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?
introduces a couple test
- grouping by `Dict<_,largeutf8>`
- mixing grouping by dictionarys and non dictionary columns
-  a 3-way group by where each column is `dict<_,_>`
- the test also have nulls sprinkled in to verify null handling

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?
the changes are test.
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?
no
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 472/878] minor: Remove `.gitignore` item for
 datafusion-examples (#23409)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
`ci/scripts/rust_example.sh` previously left generated files behind
after running, so a `.gitignore` entry was added in #14840 to improve
the developer experience.

The script has now been fixed, so this PR removes that ignore entry.
This ensures future generated files are not silently hidden by
`.gitignore`.

-The proposed refactor makes window function execution simpler and more extensible. I think it is a necessary step if we want to invest further in better vectorization or more parallel execution paradigms.
-
-The existing structure is not ideal: if we keep evolving the current shape, new optimization work will likely add more special cases and make the system harder to reason about.
-
-To sanity-check whether this refactor makes sense, we can use the potential optimizations mentioned in:
-
-- https://github.com/apache/datafusion/issues/23197
-
-The examples include better parallelism and vectorization for fixed frames, parallel execution for prefix frames, and segment-tree-based parallelism. These optimizations are natural extensions of the ideal architecture introduced by this issue, but they are hard to add cleanly with the existing structure.
-
-This issue explains, in order:
-
-- How an ideal structure should look
-- The issues in the existing implementation
-- A possible implementation plan
-
-### Ideal Architecture
-
-The gist is that we should fully separate the logical and physical layers of window execution.
-
-- Logical layer: `WindowCall` purely describes what we want to calculate. It contains the expressions for arguments, partitioning, ordering, and frame bounds.
-- Physical layer: `WindowKernel` purely provides the methods needed for execution. It represents the selected execution algorithm for a specific window call.
-
-This design brings below benefits:
-- Simplicity: the control flow is one directional, `WindowCall` decides what window kernel to use, and window kernel purely provide methods for execution.
-- Extensibility: adding new parallelism scheme/or improve vectorized fast path means adding one window kernel, no deep structural changes needed.
-
-#### Workflow
-
-```text
-SQL / logical physical planning
-  -> WindowCall              // pure description: function, args, partition/order/frame
-  -> WindowKernel selection  // physical execution protocol chosen from shape + capabilities
-  -> WindowExec              // execution routing: choose stream based on selected kernel
-      -> NaiveAccumulatorStream
-      -> SlidingAccumulatorStream
-      -> other specialized streams
-```
-
-In rough terms:
-
-```rust
-/// pure description: function, args, partition/order/frame
-struct WindowCall {
-    name: String,
-    field: FieldRef,
-    function: WindowFunctionKind,
-    args: Vec<Arc<dyn PhysicalExpr>>,
-    filter: Option<Arc<dyn PhysicalExpr>>,
-    partition_by: Vec<Arc<dyn PhysicalExpr>>,
-    order_by: Vec<PhysicalSortExpr>,
-    frame: Arc<WindowFrame>,
-    options: WindowOptions,
-}
-
-/// pure execution: provided methods needed for a specific path
-enum WindowKernel {
-    /// Derived from existing Accumulator without `retract_batch`
-    /// A nested-loop algorithm will be used.
-    NaiveAccumulator(Box<dyn NaiveAccumulatorWindowKernel>),
-    /// Derived from existing Accumulator with `retract_batch`
-    /// A sliding window algorithm will be.
-    SlidingAccumulator(Box<dyn SlidingAccumulatorWindowKernel>),
-}
-```
-
-DataFusion's existing `Accumulator` API already contains the primitives for two useful aggregate window algorithms:
-
-- `update_batch()` plus `evaluate()` can recompute a result for any frame. This supports a naive nested-loop fallback for all accumulators.
-- `retract_batch()` plus `supports_retract_batch()` allow incremental sliding-window execution when rows leave the frame.
-
-If the accumulator does not support `retract_batch()`, a naive nested-loop evaluation can be used. If `retract_batch()` is supported and the window frame is a fixed sliding frame, a sliding-window algorithm can be used for optimization.
-
-Then the implication for newly added user-defined window function is, it should only support the naive method to make it work universally (for aggregate function in window cases, it requires only `update_batch()` for the above naive path), but it can optionally support more fast paths (`retract_batch` for sliding window, or even vectorized API in the future), then the optimizer/execution will route that into the fast path if the query expression shape allows.
-
-Here is a simple example to walk through the above workflow.
-
-#### Workload 1: Sliding Aggregate
-
-Example query:
-
-```sql
-SELECT
-  avg(x) OVER (
-    PARTITION BY k
-    ORDER BY ts
-    ROWS BETWEEN 2 PRECEDING AND CURRENT ROW
-  ) AS avg_x
-FROM t;
-```
-
-Planning:
-
-1. `WindowCall` holds the logical description: `avg(x)`, `PARTITION BY k`, `ORDER BY ts`, and `ROWS BETWEEN 2 PRECEDING AND CURRENT ROW`.
-2. The planner sees that this is an aggregate window over a fixed moving frame.
-3. The planner asks the aggregate accumulator whether it supports `retract_batch()`. `avg` does;
-4. The planner chooses `SlidingAccumulatorWindowKernel`.
-5. `WindowAggExec` routes execution to a dedicated `SlidingAccumulatorStream`, because the selected kernel has the sliding-window execution protocol.
-
-The kernel API can stay small because it only represents one physical protocol:
-
-```rust
-trait SlidingAccumulatorWindowKernel {
-    fn evaluate_partition(
-        &mut self,
-        input: &PartitionWindowInput<'_>,
-        frame: &FrameIndex,
-    ) -> Result<ArrayRef>;
-}
-
-struct PartitionWindowInput<'a> {
-    batch: &'a RecordBatch,
-    args: Vec<ArrayRef>,
-    filter: Option<BooleanArray>,
-}
-```
-
-Very rough sliding-window algorithm sketch:
-
-```python
-acc = create_avg_accumulator()
-current_frame = range(0, 0)
-output = []
-
-for row_idx in partition_rows:
-    next_frame = frame_for(row_idx)
-
-    # Rows that were in the previous frame but are not in the next frame.
-    leaving = current_frame.start .. next_frame.start
-    if leaving is not empty:
-        acc.retract_batch(values_for(leaving))
-
-    # Rows that are in the next frame but were not in the previous frame.
-    entering = current_frame.end .. next_frame.end
-    if entering is not empty:
-        acc.update_batch(values_for(entering))
-
-    output.append(acc.evaluate())
-    current_frame = next_frame
-```
-
-This is the fast path: each input row is added and removed at most once, so the cost is linear in the partition size for row-based fixed frames.
-
-#### Workload 2: Naive Aggregate Fallback
-
-Example query:
-
-```sql
-SELECT
-  my_udaf(x) OVER (
-    PARTITION BY k
-    ORDER BY ts
-    ROWS BETWEEN t.n_gap PRECEDING AND CURRENT ROW
-  ) AS v
-FROM t;
-```
-
-Assume `my_udaf` is a user-defined aggregate accumulator that supports `update_batch()` and `evaluate()`, but does not support `retract_batch()`. Also the window frame `t.n_gap` preceding can be arbitrary value, it's not supported by the sliding window algorithm.
-
-Planning:
-
-1. `WindowCall` holds the logical description: `my_udaf(x)`, `PARTITION BY k`, `ORDER BY ts`, and `ROWS BETWEEN 2 PRECEDING AND CURRENT ROW`.
-2. The planner sees that this is an aggregate window (without `retract_batch()` capability), and also over a non-fixed moving frame.
-3. The planner chooses `NaiveAccumulatorWindowKernel`.
-4. `WindowAggExec` routes execution to a dedicated `NaiveAccumulatorStream`.
-
-The kernel API can again stay small:
-
-```rust
-trait NaiveAccumulatorWindowKernel {
-    fn evaluate_partition(
-        &self,
-        input: &PartitionWindowInput<'_>,
-        frame: &FrameIndex,
-    ) -> Result<ArrayRef>;
-}
-```
-
-Naive nested-loop algorithm sketch:
-
-```python
-output = []
-
-for row_idx in partition_rows:
-    frame = frame_for(row_idx)
-
-    # This is slower, but it only needs update_batch() and evaluate().
-    acc = create_my_udaf_accumulator()
-    acc.update_batch(values_for(frame))
-
-    output.append(acc.evaluate())
-```
-
-### Issue with existing implementation
-The major issue is that the existing abstraction layers leak into adjacent layers. I think the original design goal was:
-
-- `WindowExpr` is supposed to be the logical layer.
-- `PartitionEvaluator` is supposed to be the physical layer.
-
-Over time, however, these responsibilities have become mixed. The decision-making flow has become bidirectional, and the implementation now relies on special cases to work around abstraction leaks.
-
-My guess is that these are mostly hacks accumulated over the years. I cannot find a strong reason to preserve this design.
-
-### Implementation Plan
-
-I plan to do some prototyping to work out a practical refactoring plan. The known goals are:
-
-- Remove all three `WindowExpr` implementations and use `WindowCall` as the pure logical layer.
-- Use `WindowKernel` to replace the `PartitionEvaluator`
-    - `PartitionEvaluator` is now a large trait that uses 3+ flags to decide behavior. I think it is hard to use and extend; small, focused traits inside `WindowKernel` enum variants should be better.
-    - Provide an adapter like `WindowKernel::LegacyPartitionEvaluator` to make the refactor practical.
-- Evolve `WindowAggExec` in this direction and avoid changing `BoundedWindowAggExec`
-    - See https://github.com/apache/datafusion/issues/23197#issuecomment-4806401319

Subject: [PATCH 474/878] perf: avoid intermediate slice allocation in Spark
 slice function (#23481)

## Which issue does this PR close?

- N/A (small performance improvement)

## Rationale for this change

The Spark `slice` function's `calculate_start_end` helper reads the
length of each list element in a per-row hot loop via
`values.value(row).len()`. `GenericListArray::value(row)` materializes a
new `ArrayRef` for the sublist on every iteration purely to call
`.len()` on it. The length is already available from the offset buffer,
so this allocation is pure overhead.

Replacing it with `values.value_length(row)` reads the length directly
from the offsets with no allocation.

Benchmarked with the existing `datafusion/spark/benches/slice.rs` over
1M rows:

| case | before | after | improvement |
|------|--------|-------|-------------|
| List(Int64), array args | 54.0 ms | 40.0 ms | ~26% faster |
| List(Int64), scalar args | 88.4 ms | 69.8 ms | ~21% faster |

## What changes are included in this PR?

A single-line change in `datafusion/spark/src/function/array/slice.rs`
replacing `values.value(row).len() as i64` with
`values.value_length(row) as i64`.

## Are these changes tested?

Covered by existing unit tests in
`datafusion/spark/src/function/array/slice.rs` and slt coverage for the
Spark `slice` function; behavior is unchanged. The performance impact
was measured with the existing `slice` criterion benchmark.

## Are there any user-facing changes?

No.

Subject: [PATCH 476/878] feat: Support List/ListView types in approx_distinct
 (#23443)

## Which issue does this PR close?

- Relates to https://github.com/apache/datafusion/issues/22989 but does
not close it. More types are coming.


## Rationale for this change

- Support the Arrow types `List` `LargeList`, `FixedSizeList`,
`ListView`, `LargeListView` type for `approx_distinct`

## What changes are included in this PR?

- Enable `HLLAccumulator` and `HllGroupsAccumulator` to support `List`
`LargeList`, `FixedSizeList`, `ListView`, `LargeListView`
- Tests for the non-grouped and grouped path as part of `aggregate.slt`

## Are these changes tested?

Yes

## Are there any user-facing changes?

Yes, `approx_distinct` supports now `List` `LargeList`, `FixedSizeList`,
`ListView`, `LargeListView` but no breaking changes.

Subject: [PATCH 477/878] refactor(hash-aggr): Migrate single mode hash
 aggregation (#23408)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of https://github.com/apache/datafusion/issues/22710


## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

This PRs implements the single aggregation (fused partial and final
aggregation into a single physical plan operator). This mode can be
planed if input is already hash/range partitioned.

See comments at datafusion/physical-plan/src/aggregates/single_stream.rs
for details.



## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
- Adds an `AggregateHashTable<SingleMarker>` variant to handle single
aggregation.
- Adds `SingleHashAggregateStream` that uses
`AggregateHashTable<SingleMarker>` to implement the single aggregation
state machine.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Existing tests for functionalities + UT for planning

## Are there any user-facing changes?
No
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 478/878] test: add sqllogictest coverage for DISTINCT / GROUP
 BY / aggregation on map columns (#23406)

## Which issue does this PR close?

- Closes #15428.

## Rationale for this change

`SELECT DISTINCT` on map columns used to fail with
`ArrowError(NotYetImplemented)` because arrow-rs's `RowConverter` did
not support Map types. That support has since landed upstream
(apache/arrow-rs#7879) and is available on DataFusion main via arrow
59.1, so these queries now work. As suggested in
https://github.com/apache/datafusion/issues/15428#issuecomment-4911477288
(maintainer comment), this PR adds sqllogictest coverage to lock in the
behavior and close the issue.

## What changes are included in this PR?

Adds a new test section to `datafusion/sqllogictest/test_files/map.slt`
covering:

- `SELECT DISTINCT` on a map column, including the exact reproducer from
the issue (`DISTINCT ... LIMIT`), collapsing of duplicate maps and
duplicate NULLs, and `DISTINCT` over map + scalar columns together
- `GROUP BY` on a map column, `GROUP BY` map + scalar keys, and `HAVING`
with a map grouping key
- Aggregations with map inputs: `COUNT(map)`, `COUNT(DISTINCT map)`,
`SUM` grouped by map, and `array_agg` of map values
- Edge cases: empty maps under `DISTINCT` (equal to each other, distinct
from `NULL`), NULL maps, and unsorted maps with the same entries in
different order being treated as distinct values
- `UNION` (distinct) on map columns
- `DISTINCT` / `GROUP BY` over the existing 209-row
`parquet_map.parquet` file for coverage on real Parquet-backed map data

Note: a bare `MAP {'key': NULL}` literal infers a `Null` value type and
fails type coercion across a VALUES list against `Map(Utf8, Int64)`
rows, so the test uses `CAST(NULL AS BIGINT)` for the null map value.
That coercion gap may be worth a separate follow-up issue.

## Are these changes tested?

Yes, this PR is test-only. All tests pass locally via `cargo test -p
datafusion-sqllogictest --test sqllogictests -- map.slt`.

## Are there any user-facing changes?

No. Test-only change; no API or behavior changes.

Subject: [PATCH 479/878] refactor: Migrate ScalarSubqueryExpr to
 self-serialization proto pattern (#23130)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move ScalarSubqueryExpr proto encode/decode into the expression itself
via the try_to_proto / try_from_proto hooks, removing the centralized
downcast branch in to_proto.rs and the inline construction in
from_proto.rs. Because the ScalarSubqueryResults container is
runtime-only shared state and not part of the wire format, from_proto.rs
still fetches it from the decode context and threads it into
try_from_proto.

Follows the pattern established in #21929.

## Which issue does this PR close?

- Closes #[22433](https://github.com/apache/datafusion/issues/22433).

## Rationale for this change

datafusion-proto serializes ScalarSubqueryExpr by downcasting in
to_proto.rs and rebuilding it inline in from_proto.rs, which forces its
internal fields to be exposed as public accessors just for the proto
crate.

PR #[21929](https://github.com/apache/datafusion/pull/21929) introduced
a self-serialization pattern (try_to_proto / try_from_proto) where each
expression owns its own wire format and the central dispatch just
delegates. Other expressions like InListExpr and
DynamicFilterPhysicalExpr already use it. This change moves
ScalarSubqueryExpr to the same pattern, removing its bespoke proto
branches and the proto-only public accessors.

One wrinkle: ScalarSubqueryExpr's ScalarSubqueryResults is runtime-only
shared state, not part of the wire format, so try_from_proto takes it as
an extra argument that from_proto.rs threads in from the decode context.

## What changes are included in this PR?

- [x] `try_to_proto` in `impl PhysicalExpr for ScalarSubqueryExpr` (not
inherent), `#[cfg(feature = "proto")]`
- [x] `ScalarSubqueryExpr::try_from_proto` wired into `from_proto.rs`
- [x] central `to_proto.rs` + `from_proto.rs` arms deleted in this PR
- [x] direct hook test incl. bad-input case; test module at end of file
- [x] roundtrip tests pass; fmt + clippy `-D warnings` clean; PR
template filled in

## Are these changes tested?

- **Unit tests** (`scalar_subquery.rs`, `#[cfg(all(test, feature =
"proto"))]` module at end of file) exercise the hooks directly:
- `round_trips_through_proto` — encode via `try_to_proto`, decode via
`try_from_proto`, asserting `data_type`/`nullable`/`index` and
shared-results identity survive.
- `rejects_non_scalar_subquery_node` — wrong `ExprType` variant errors
cleanly.
  - `rejects_missing_data_type` — missing required field errors cleanly.
- **Round-trip integration tests** (`datafusion-proto`,
`--all-features`) cover the full plan path:
`roundtrip_scalar_subquery_exec`,
`roundtrip_nested_scalar_subquery_exec_scopes_results`, and
`roundtrip_scalar_subquery_exec_with_default_converter_executes`.

All pass, and `cargo fmt --all` + `cargo clippy --all-features
--all-targets -- -D warnings` are clean.

## Are there any user-facing changes?

No

Subject: [PATCH 480/878] perf: optimize make_date in datafusion-functions
 (#23470)

## Which issue does this PR close?

N/A
## Rationale for this change

Optimize existing expression.

## What changes are included in this PR?

Replaced make_date's per-element triple is_null check + PrimitiveBuilder
with a single unioned NullBuffer, raw value-slice reads, and direct
PrimitiveArray::new construction (matching the already-optimized
make_time), cutting per-row overhead on the hot valid-input path.

## Are these changes tested?

Existing tests + new tests.

Benchmark (criterion):

- make_date_scalar_col_col_8192: 19.979% faster (base 31210ns -> cand
24974ns)
- make_date_col_col_col_8192: 16.931% faster (base 30849ns -> cand
25626ns)
- make_date_scalar_scalar_col_8192: 22.999% faster (base 31551ns -> cand
24295ns)
- make_date_scalar_scalar_scalar: 1.271% faster (base 48ns -> cand 48ns)


## Are there any user-facing changes?

No

<!--
If there are user-facing changes then we may require documentation to be

Subject: [PATCH 482/878] feat: add array_first higher-order array function
 (#23267)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
-->

No dedicated tracking issue; this adds a single self-contained
higher-order array function. Happy to file one if preferred.

## Rationale for this change

DataFusion already provides higher-order array functions such as
`array_any_match`, `array_filter`, and `array_transform`, but there is
no direct way to retrieve the *first* element of an array that satisfies
a predicate. Today this requires `array_filter` followed by
`array_element(..., 1)`, which materializes an intermediate filtered
array. `array_first` expresses this directly and rounds out the set of
lambda-based array functions.

## What changes are included in this PR?

- New higher-order function `array_first(array, predicate)` (alias
`list_first`) in `datafusion-functions-nested`, returning the first
element for which the lambda predicate returns `true`:
  - returns `null` when the array is empty or no element matches;
- a predicate that evaluates to `null` for an element is treated as not
matching;
  - a matched element that is itself `null` is returned as `null`.
- Implemented as a `HigherOrderUDFImpl` following the existing
array-lambda functions, including the standard fast paths (fully-null
input) and correct handling of sliced lists, null sublists, and captured
outer columns.
- Registration in `functions-nested` (`expr_fn` re-export and the
default higher-order function list).
- Unit tests, sqllogictest coverage, and regenerated SQL function
documentation.

## Are these changes tested?

Yes:
- Unit tests in `array_first.rs` covering match/no-match, empty and null
arrays, null-predicate handling, matched-null elements, sliced lists,
captured outer columns, and non-primitive element types.
- sqllogictest cases in `test_files/array/array_first.slt`, including
`LargeList` and the `list_first` alias.

## Are there any user-facing changes?

Yes. A new array function `array_first` (alias `list_first`) is
available in SQL, with generated documentation under the Array Functions
section. There are no breaking changes to existing public APIs.

+### `array_first`
+
+Returns the first element of an array that satisfies the given predicate. Returns null if the array is empty or no element matches. A predicate that returns null for an element is treated as not matching.
+
+```sql
+array_first(array, predicate)
+```
+
+#### Arguments
+
+- **array**: Array expression. Can be a constant, column, or function, and any combination of array operators.
+- **predicate**: Lambda predicate that returns a boolean. The first element for which it returns true is returned.
+
+#### Example
+
+```sql
+> select array_first([1, 2, 3, 4], x -> x > 2);
++----------------------------------------+
+| array_first([1,2,3,4],x -> x > 2)      |

Subject: [PATCH 483/878] Decode Hive partition values in listing tables
 (#23226)

## Which issue does this PR close?

- Closes #19650.

## Rationale for this change

Hive-style partition values can contain percent-encoded characters in
object-store paths, such as `%2F` for `/` or `%20` for a space.
`parse_partitions_for_path` currently returns those encoded bytes
literally, so listing tables expose `foo%2Fbar` instead of `foo/bar`.

## What changes are included in this PR?

- Percent-decode extracted partition values in
`parse_partitions_for_path`.
- Return `Cow<str>` from the parser so unchanged values keep the
borrowed fast path and decoded values can be owned only when needed.
- Fall back to the original raw partition value if percent decoding does
not produce valid UTF-8, rather than dropping the file from listing
results.
- Add helper-level and `PartitionedFile` conversion tests for decoded
partition values.

## Are these changes tested?

- `cargo fmt --all --check`
- `cargo test -p datafusion-catalog-listing`

Subject: [PATCH 484/878] ci: Use `install-action` instead of `cargo install`
 to speed up CI (#23477)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
For CI dependencies installed with `cargo install`, it's possible to use
`install-action` instead for faster setup. (former compiles the binary,
the latter directly download the release version) , each of them should
get ~1min faster.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
- Use `install-action` instead of `cargo install` for existing CI jobs
- Add a new CI job to enforce this convention (`grep cargo install` for
all Github Action scripts)

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 485/878] feat: Expose cache hits in list_files_cache function
 (#23439)

## Which issue does this PR close?

- Closes None.

## Rationale for this change

Follow up to https://github.com/apache/datafusion/pull/22613 and
https://github.com/apache/datafusion/pull/23253. Cache hits are now
supported for all memory-limiting caches. Therefore it makes sense to
expose them in the `list_files_cache` function the same way the
`metadata_cache` and `statistics_cache` functions do it already.

## What changes are included in this PR?

- Add cache hits to the `list_files_cache` function
- Tests
- Adapt documentation for the `list_files_cache` function

## Are these changes tested?

Yes.

## Are there any user-facing changes?

Yes, the `list_files_cache` function supports now cache hits but no
breaking changes.

Subject: [PATCH 486/878] fix: Batch size limit in re-spill compounds (#23286)

This fixes an issue in my previous design for the re-spill in sort -
whenever we half a stream, we half self.batch_size, even if its not the
same stream being halved, so for each re-spill we get a smaller and
smaller output batch, which really hurts performance in the merge.
We can avoid it by just keeping the batch_size_limit in the spilled file
struct. then we just use the lowest limit whenever we merge N streams,
making it dynamic and much more robust.

Has tests.

Does not break API

Subject: [PATCH 487/878] Add minimal genarator-like stream implementation
 (#23530)

## Which issue does this PR close?

None, related to PR #23407

## Rationale for this change

Manually writing `Stream` implementations can be quite tedious since it
requires implementing the state machine of the stream yourself. This
often results in hard to read code. The same problem exists with manual
`Future` implementations and `async` was added to the Rust language to
mitigate exactly this problem. Unfortunately there's no language level
support yet to help with writing streams/generators.

There are quite a few projects that attempt to fill this gap:
- Tokio's
[async_stream](https://docs.rs/async-stream/latest/async_stream/)
provides a proc macro that recognises a `yield` keyword. This is a good
implementation, but proc macros don't play nice with code formatting,
increase compile time, and in this particular case prevent decomposition
into smaller functions.
-
[async_fn_stream](https://docs.rs/async-fn-stream/latest/async_fn_stream/)
provides an implementation of the same concept, but without the proc
macro. Unfortunately this implementation chooses a heavier mechanism to
communicate generated values back to the stream via a `SmallVec`.
-
[genawaiter](https://docs.rs/genawaiter/latest/genawaiter/sync/index.html)
is a more general purpose generator library, but this can also be used
to implement `Stream`s. This project does miss some of the ergonomics
provided by the other two in the form of `try_` variants that help in
implementing fallible streams.

Since none of these variants seems like the ideal candidate, the best
option might be to have a custom implementation of the concept tailored
to the needs of the DataFusion project. This PR provides an initial
draft of exactly that.

## What changes are included in this PR?

- Adds `async_stream` and `async_try_stream` functions that create
Stream implementations based on an async generator function.

The initial implementation was inspired by the macro expansion produced
by `async_stream`. The code was then adapted further taking inspiration
from the two other libraries. Specifically, the `Emitter` terminology
was taken from `async_fn_stream` and the `Arc<Mutex<Option<T>>>` value
transfer mechanism was taken from `genawaiter`.

`async_stream` uses a very light weight thread-local storage based
mechanism to handle value transfer, but this felt too risky to use when
the emitter is exposed. It makes sense in the Tokio implementation since
the proc macro can manage control flow in a stricter way.

I wasn't entirely sure if taking some inspiration from has code
licensing implications. I applied ASLv2 for now on the added code.

## Are these changes tested?

Test code was mainly adapted from the tokio implementation.

## Are there any user-facing changes?

Yes, new public function `async_stream` and `async_try_stream`

Subject: [PATCH 488/878] refactor(physical-plan): externalize statistics
 traversal into StatisticsContext (#23051)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22958.

## Rationale for this change

Follow-up to #21815. Per @2010YOUY01's suggestion there, this decouples
statistics
traversal/caching from each operator's computation: operators now
express only local
propagation, while the walk and cache live in an external
`StatisticsContext`.

## What changes are included in this PR?

- `StatisticsContext` owns the bottom-up walk + per-walk cache;
`compute(plan, args)`
  resolves children, then calls the operator.
- `ExecutionPlan::statistics_from_inputs(input_stats, args)` — stateless
local
propagation from pre-resolved child stats; default delegates to
deprecated
  `partition_statistics`.
- `ExecutionPlan::child_stats_requests(partition) -> Vec<ChildStats>` —
per-child
directive (`At(Option<usize>)` / `Skip`) for which partition each child
is computed
at (e.g. broadcast joins request the build side overall; `UnionExec`
skips
  non-owning inputs).
- Removes the unreleased `statistics_with_args`; `partition_statistics`
stays
  deprecated.
- Migrates all operators/callers; updates the 55.0.0 upgrade guide.

## Are these changes tested?

Yes — existing statistics tests now run through
`StatisticsContext::compute`, plus new
unit tests for the cache and the `compute_statistics` benchmark.

## Are there any user-facing changes?

Yes (public `ExecutionPlan` API): `partition_statistics` deprecated in
favor of
`statistics_from_inputs`; new `StatisticsContext` / `ChildStats`;
unreleased
`statistics_with_args` removed. Upgrade guide updated.

---

Reviewer note: `statistics_from_inputs` takes `args: &StatisticsArgs`
(currently just
`partition`) as a non-breaking extension seam rather than a bare
`partition` — happy
to change if preferred (see #22958).

----

Disclaimer: I used AI to assist in the code generation, I have manually
reviewed the output and it matches my intention and understanding.

+`ExecutionPlan::partition_statistics` is deprecated. Statistics computation is

+- `StatisticsContext` owns the bottom-up plan-tree traversal and a per-walk
+  cache of memoized child statistics. Call `StatisticsContext::compute` to
+  obtain statistics for a plan.
+- `ExecutionPlan::statistics_from_inputs` computes a node's statistics from its
+  children's already-resolved statistics, which the context passes in. The node
+  does not traverse the tree itself.
 
 Existing implementations of `partition_statistics` continue to work unchanged.

Subject: [PATCH 489/878] perf: Extend WindowTopN to support RANK (#22885)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Related to https://github.com/apache/datafusion/issues/6899
(DENSE_RANK to follow in a separate PR will close it).

  ## Rationale for this change

PR #21479 introduced `WindowTopN` for `ROW_NUMBER` only; `RANK` and
`DENSE_RANK` were explicitly out of scope. This PR extends the rule to
`RANK`, replacing the full sort under `Filter(rk≤K) → Window(RANK) →
Sort` with a per-partition heap-of-K plus a boundary-tie buffer.

  ## What changes are included in this PR?

- **`datafusion/physical-plan/src/topk/mod.rs`** — new `pub(crate)
struct PartitionedTopKRank` (sibling of
`PartitionedTopK` from #23096) with per-partition `RankPartitionState {
TopKHeap, Vec<TieEntry> }`.
- **`datafusion/physical-plan/src/sorts/partitioned_topk.rs`** —
`WindowFnKind` enum (`RowNumber` / `Rank`).
`do_partitioned_topk` dispatches on `fn_kind` to
`PartitionedTopK::try_new` or `PartitionedTopKRank::try_new`;
- **`datafusion/physical-optimizer/src/window_topn.rs`** —
`is_row_number` → `supported_window_fn(expr) ->
Option<WindowFnKind>`; empty-`order_by` guard for RANK; `WindowFnKind`
plumbed through `PartitionedTopKExec::try_new`.
- **`datafusion/sqllogictest/test_files/window_topn.slt`** — RANK SLT
cases: basic, strict (`<`), flipped (`>=` / `>`),
boundary ties, ties spanning ob values, empty-`ORDER BY` (rule must NOT
fire), mixed window functions, ASC/DESC × NULLS FIRST/LAST, QUALIFY.
- **`datafusion/core/tests/physical_optimizer/window_topn.rs`** — 6 new
RANK rule unit tests covering predicate
  matching, partition-by/order-by guards, dense_rank skip.
- **`benchmarks/queries/h2o/window.sql`** — six new RANK queries
(Q14–Q17, Q22, Q23) covering partition counts from ~100 to ~100K, low
and heavy tie densities.

h2o `window` benchmark, 10M-row `large` table, RANK top-2, 3-iteration
average. Toggle via `DATAFUSION_OPTIMIZER_ENABLE_WINDOW_TOPN`.

 | Variant | Partitions | OFF (rule disabled) | ON (rule enabled) | Δ |
  |---|---:|---:|---:|:---:|
| RANK low ties (`id3 % 100`) | ~100 | 305 ms | **107 ms** | **2.84×
faster** ✓ |
| RANK low ties (`id3 % 1000`) | ~1K | 263 ms | **120 ms** | **2.19×
faster** ✓ |
| RANK heavy ties (`id3 % 1000`, `v2 % 10` OB) | ~1K | 282 ms | **125
ms** | **2.25× faster** ✓ |
| RANK low ties (`id2`) | ~10K | 363 ms | **140 ms** | **2.59× faster**
✓ |
| RANK heavy ties (`id2`, `v2 % 10` OB) | ~10K | 291 ms | **143 ms** |
**2.04× faster** ✓ |
| RANK low ties (`id3 % 100K`) | ~100K | 241 ms | 422 ms | 1.75× slower
|

  ## Are these changes tested?

  Yes:

  - `cargo test -p datafusion-physical-plan --lib` — 1455 passed
  - `cargo test -p datafusion-physical-optimizer --lib` — 27 passed
- `cargo test -p datafusion --test core_integration
physical_optimizer::window_topn::` — 13 passed (7 ROW_NUMBER + 6 RANK)
  - `cargo test --test sqllogictests -- window_topn` — passed

  ## Are there any user-facing changes?

The existing `optimizer.enable_window_topn` config flag (default
`false`) now also covers `RANK` queries. No public API additions

Subject: [PATCH 495/878] feat: Support Map type in approx_distinct (#23526)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Relates to https://github.com/apache/datafusion/issues/22989 but does
not close it. More types are coming.


## Rationale for this change

- Support the Arrow types `Map` type for `approx_distinct`

## What changes are included in this PR?

- Enable `HLLAccumulator` and `HllGroupsAccumulator` to support `Map`
- Tests for the non-grouped and grouped path as part of `aggregate.slt`

## Are these changes tested?

Yes and  results are compared to DuckDB:

```
D CREATE TABLE approx_distinct_map_test AS SELECT * FROM (VALUES
    (1, MAP {'a': 1, 'b': 2}), (1, MAP {'a': 1, 'b': 2}), (1, MAP {'c': 3}),
    (2, MAP {'d': 4}), (2, NULL),
    (3, NULL), (3, NULL),
    (4, MAP {'e': 5})
  ) AS t(g, m);

D SELECT approx_count_distinct(m) FROM approx_distinct_map_test WHERE g = 1;
┌──────────────────────────┐
│ approx_count_distinct(m) │
│          int64           │
├──────────────────────────┤
│            2             │
└──────────────────────────┘

D SELECT g, approx_count_distinct(m) FROM approx_distinct_map_test GROUP BY g ORDER BY g;
┌───────┬──────────────────────────┐
│   g   │ approx_count_distinct(m) │
│ int32 │          int64           │
├───────┼──────────────────────────┤
│     1 │                        2 │
│     2 │                        1 │
│     3 │                        0 │
│     4 │                        1 │
└───────┴──────────────────────────┘

D SELECT approx_count_distinct(m) FROM approx_distinct_map_test;
┌──────────────────────────┐
│ approx_count_distinct(m) │
│          int64           │
├──────────────────────────┤
│            4             │
└──────────────────────────┘
```

## Are there any user-facing changes?

Yes, `approx_distinct` supports now `Map` but no breaking changes.

## Rationale for this change

Optimise `date_part` to avoid extra operations during `isodow` - Arrow's
`DayOfWeekMonday1` is now available

## What changes are included in this PR?

Switch from manual dow calculation to a built-in `DayOfWeekMonday1`

## Are these changes tested?

- Covered by existing SLTs
- Benched by recently introduced benchmarks

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

Subject: [PATCH 499/878] perf: optimize `round` expression (#23471)

## Which issue does this PR close?

N/A

## Rationale for this change

Optimize an existing function

## What changes are included in this PR?

round() over a no-null float column with scalar decimal_places now
hoists the 10^dp factor out of the loop and uses the vectorizable
infallible `unary` kernel instead of per-element `try_unary`+`powi`,
with a fallback preserving bit-identical output for null/array cases.

## Are these changes tested?

Existing tests

Benchmark (criterion):

- 8192: 28.689% faster (base 2711ns -> cand 1933ns)
- 4096: 41.544% faster (base 1382ns -> cand 808ns)
- 1024: 25.253% faster (base 451ns -> cand 337ns)
- 8192: 44.103% faster (base 1486ns -> cand 831ns)
- 4096: 29.01% faster (base 679ns -> cand 482ns)
- 1024: 20.457% faster (base 291ns -> cand 231ns)


## Are there any user-facing changes?

No

Subject: [PATCH 500/878] perf: optimize `string_trim` (#23541)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Optimize existing expression.

## What changes are included in this PR?

Build the trimmed Utf8/LargeUtf8 output by writing slices into a single
exactly-sized value buffer and reusing the input null buffer, instead of
collecting through arrow's FromIterator, which starts its value buffer
at 1024 bytes, grows it by repeated doubling, and rebuilds the null
bitmap row by row.

## Are these changes tested?

Existing tests.

Subject: [PATCH 502/878] perf: optimize `date_trunc` (#23542)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Optimize existing expression.

## What changes are included in this PR?

Replaced the per-row chrono NaiveDateTime round trip in the untimezoned
coarse path of date_trunc (week/month/quarter/year) with integer
civil-calendar arithmetic, cutting several allocationless-but-validating
chrono field setters down to a few integer ops per row.

## Are these changes tested?

Existing tests.

Benchmark (criterion):

- date_trunc_month_nanos_1000: 48.452% faster (base 19164ns -> cand

Subject: [PATCH 503/878] perf(physical-expr): cache remapped expression in
 DynamicFilterPhysicalExpr::current() (#23532)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23533.

## Rationale for this change

`DynamicFilterPhysicalExpr::current()` is invoked per batch on the
RowFilter path (via `PhysicalExpr::evaluate`). It calls
`remap_children`, which does a `transform_up` tree walk. For dynamic
filters that carry a large `InListExpr` — e.g. `HashJoinExec` pushing
down a `col IN build_keys` list of ~150+ values — that walk is dominated
by `InListExpr::with_new_children` cloning the whole list on every call.

The `inner.generation` only changes when the filter is `update`d — once
per HashJoin build, or once per TopK threshold refresh. Between updates
every `current()` call recomputes an identical remapped tree. Caching
per generation lets per-batch calls short-circuit the walk.

### Measured impact (TPCH SF1, 10 iterations)

| | HEAD `pushdown=true` | This PR `pushdown=true` | Baseline
`pushdown=false` |
|---|---|---|---|
| **Q17** | 128 ms | **53 ms** (**2.4× faster**) | 55 ms |
| Q18 | 69 ms | 56 ms | 49 ms |
| Total (22 queries) | 743 ms | 644 ms (**-13%**) | 531 ms |

Q17 (Nation-in-orders subquery) matches the `pushdown=false` baseline
after the fix — the DynamicFilter tax is fully eliminated on that shape.
Row counts identical across all 22 queries pre/post fix.

Profile before the fix: `InListExpr::with_new_children` and its
`drop_glue` sat at the top of Q17's samply flamegraph.

Part of #20324 (parquet filter-pushdown regression EPIC).

## What changes are included in this PR?

- Add `current_cache: Arc<RwLock<Option<(u64, Arc<dyn PhysicalExpr>)>>>`
on `DynamicFilterPhysicalExpr` (aliased as `CurrentExprCache` to keep
the type readable).
- `current()`: read the current `(expr, generation)` from `inner`,
return the cached `Arc` if the cached generation matches; otherwise
recompute via `remap_children` and store the new pair under a write
lock.
- Reset semantics:
- `update()` bumps `inner.generation`, so the next `current()` misses
the cache and recomputes.
- `with_new_children` clones the outer struct with new
`remapped_children`; the derived filter gets its own fresh cache slot.
  - `from_parts` (proto deserialization) starts with an empty cache.
- No public API changes.

## Are these changes tested?

Yes — three new regression tests in
`expressions::dynamic_filters::test`:

- `test_current_cache_hits_within_generation` — three consecutive
`current()` calls return the same `Arc` (pointer-equal) at the same
generation, proving the remap walk did not re-run.
- `test_current_cache_invalidates_on_update` — after `update()` bumps
the generation, `current()` returns a fresh `Arc` (not pointer-equal,
and stringly distinct).
- `test_current_cache_is_per_derived_filter` — two filters derived via
`with_new_children` with different `remapped_children` produce distinct
cached `Arc`s and each hits its own cache on subsequent calls.

All 21 tests in `expressions::dynamic_filters` (18 existing + 3 new)
pass.

## Are there any user-facing changes?

No. Internal caching only. No public API changes; behavior is identical
modulo the generation-tied fast path.

Subject: [PATCH 504/878] feat: allow Partitioning::Range to satisfy window
 Distribution::KeyPartitioned requirements (#23416)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23289.

Rebased on main now that #23184 has merged. Overlaps with #23355, which
also opts the window execs into range satisfaction as part of its
PartitionedTopK work — happy to rebase whichever lands second.

## What changes are included in this PR?

In one commit:

* Opt `WindowAggExec` and `BoundedWindowAggExec` with partition keys
into range satisfaction via
`InputDistributionRequirements::allow_range_satisfaction_for_key_partitioning`,
mirroring `AggregateExec`. Compatible range-partitioned inputs then
satisfy the window key requirement without a hash repartition; subset
satisfaction and the hash fallback for incompatible keys come from the
existing satisfaction machinery. Windows without `PARTITION BY` keep
requiring a single partition.

## Are these changes tested?

Yes: new `slt` tests in `range_partitioning.slt` (exact and subset
reuse, rehash on incompatible keys, `subset_repartition_threshold` /
`preserve_file_partitions` / `target_partitions` behavior,
`WindowAggExec` via an unbounded frame, and no-`PARTITION BY`), plus
plan-shape tests in `enforce_distribution.rs` and acceptance/rejection
tests in `sanity_checker.rs`.

## Are there any user-facing changes?

Subject: [PATCH 505/878] doc: More comments to aggregate planning overview
 (#23525)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

Part of https://github.com/apache/datafusion/issues/22710


## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
There are currently around 10 specialized aggregation implementations
(streams such as AggregateStream). We have comments describing each
variant, but no high-level overview. This PR adds one.

It's mostly a aggregate planning overview, and brief intuitions about
existing aggregate streams, plus pointers.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

 // specific language governing permissions and limitations
 // under the License.
 
-//! Aggregates functionalities
+//! Aggregate functionality
+//!
+//! # Aggregate planning
+//!
+//! DataFusion selects different aggregate implementations (streams) based on the
+//! query shape and configuration. This section provides an overview of the
+//! available stream variants.
+//!
+//! See each stream's documentation for details.
+//!
+//! ## 1. Two-stage hash aggregation
+//!
+//! Two-stage hash aggregation is used for regular parallel execution.
+//!
+//! The input passes through three execution operators to produce the final
+//! aggregation result:
+//!
+//! 1. Partial aggregation reads the input and produces partial states. It
+//!    aggregates independently within each partition, which usually reduces
+//!    cardinality before the later shuffle.
+//! 2. Hash repartitioning on the group keys sends all partial states for each
+//!    group to the same output partition for final aggregation.
+//! 3. Final aggregation reads the partial states, combines them, and emits the
+//!    final results.
+//!
+//! ```text
+//! AggregateExec (final)
+//!   RepartitionExec (hash by group keys)
+//!     AggregateExec (partial)
+//! ```
+//!
+//! See [`PartialHashAggregateStream`] and [`FinalHashAggregateStream`] for details.
+//!
+//! ### Ordering optimization
+//!
+//! When the input is ordered by the group key, an ordered fast path is used. It
+//! uses a similar two-stage hash aggregation with an early-emission optimization.
+//!
+//! ```text
+//! AggregateExec (final, ordered)
+//!   RepartitionExec (hash by group keys, order-preserving)
+//!     AggregateExec (partial, ordered)
+//! ```
+//!
+//! See [`OrderedPartialAggregateStream`] and [`OrderedFinalAggregateStream`] for
+//! details.
+//!
+//! Related configuration:
+//!
+//! - [`datafusion.execution.target_partitions`](datafusion_common::config::ExecutionOptions::target_partitions)
+//! - [`datafusion.optimizer.repartition_aggregations`](datafusion_common::config::OptimizerOptions::repartition_aggregations)
+//! - [`datafusion.optimizer.prefer_existing_sort`](datafusion_common::config::OptimizerOptions::prefer_existing_sort)
+//!
+//! ## 2. Single-stage hash aggregation
+//!
+//! When there is a single partition, or the aggregation input is already
+//! key-partitioned (e.g., a data source has existing range partitioning),
+//! `Single` mode aggregation is used.
+//!
+//! It takes raw input and directly produces the final result.
+//!
+//! ```text
+//! AggregateExec (mode=Single or SinglePartitioned)
+//!   input
+//! ```
+//!
+//! See [`SingleHashAggregateStream`] for details.
+//!
+//! Related configuration:
+//!
+//! - [`datafusion.execution.target_partitions`](datafusion_common::config::ExecutionOptions::target_partitions)
+//! - [`datafusion.optimizer.repartition_aggregations`](datafusion_common::config::OptimizerOptions::repartition_aggregations)
+//!
+//! ## 3. Aggregation without grouping expressions
+//!
+//! A global aggregate maintains one accumulator set per input partition rather
+//! than a hash table of groups. Partial stages compute local states and a final
+//! stage combines them into one output row:
+//!
+//! ```text
+//! AggregateExec (final, no-grouping)
+//!   CoalescePartitionsExec
+//!     AggregateExec (partial, no-grouping)
+//! ```
+//!
+//! Every stage without grouping expressions uses [`AggregateStream`]. This path
+//! is selected before the grouped-stream migration setting is considered.
+//!
+//! ## 4. Grouped TopK aggregation
+//!
+//! When a query only needs the best `N` groups, retaining every group in a hash
+//! table and sorting them afterward does unnecessary work. The optimizer pushes
+//! the sort limit and direction into the aggregate:
+//!
+//! ```text
+//! SortExec (fetch=N)
+//!   AggregateExec (limit=N, order=...)
+//!     input
+//! ```
+//!
+//! [`GroupedTopKAggregateStream`] keeps a bounded priority map for a single group
+//! key. It supports group-by-only queries and compatible `MIN` or `MAX`
+//! aggregates. An unordered group-by-only soft limit instead stays on the normal
+//! hash aggregation path.
+//!
+//! Related configuration:
+//!
+//! - [`datafusion.optimizer.enable_topk_aggregation`](datafusion_common::config::OptimizerOptions::enable_topk_aggregation)
+//! - [`datafusion.optimizer.enable_distinct_aggregation_soft_limit`](datafusion_common::config::OptimizerOptions::enable_distinct_aggregation_soft_limit)
+//!
+//! ## 5. Partial-reduce hash aggregation
+//!
+//! This implementation will not be planned by DataFusion SQL interface, it must be
+//! manually constructed at [`ExecutionPlan`] level.
+//!
+//! This mode is useful in a distributed setting.
+//!
+//! See [`PartialReduceHashAggregateStream`] for details.
+//!
+//! ## 6. Fallback grouped hash aggregation
+//!
+//! [`GroupedHashAggregateStream`] is the legacy implementation for several of the
+//! stream types above. It is being incrementally migrated to separate streams.
+//!
+//! See the issue for details: <https://github.com/apache/datafusion/issues/22710>

Subject: [PATCH 507/878] Preserve string slice function return types (#23330)

## Which issue does this PR close?

- Closes #23329.

## Rationale for this change

`left`, `right`, and `substr` currently always return `Utf8View`, even
when their first argument is `Utf8` or `LargeUtf8`. This makes them
inconsistent with nearby string-producing functions such as `lower`,
`upper`, `reverse`, `translate`, and `substr_index`, which preserve the
first argument's string type.

The unconditional `Utf8View` return type also means callers that
intentionally avoid view types cannot keep `Utf8` flowing through these
functions without explicit casts back to `Utf8`, even when they
explicitly opt out of view types with
`datafusion.sql_parser.map_string_types_to_utf8view=false` and
`datafusion.execution.parquet.schema_force_view_types=false`.

This PR revisits the performance tradeoff from #21441 / #21442 and makes
these functions follow the same input-driven return-type contract as the
other string functions.

## What changes are included in this PR?

- Change `left`, `right`, and `substr` return type inference to use the
first argument's string type.
- Return `StringArray` / `LargeStringArray` for `Utf8` / `LargeUtf8`
inputs.
- Keep the optimized `StringViewArray` path for `Utf8View` inputs.
- Update unit tests and sqllogictests to cover `Utf8`, `LargeUtf8`, and
`Utf8View` return types.

## Are these changes tested?

Yes.

## Are there any user-facing changes?

Yes. `left`, `right`, and `substr` now preserve the first argument's
string type:

- `Utf8 -> Utf8`
- `LargeUtf8 -> LargeUtf8`
- `Utf8View -> Utf8View`

This may remove implicit downstream casts for users that expect `Utf8`,
but it also means `Utf8` / `LargeUtf8` inputs no longer use the previous
zero-copy `Utf8View` result representation.

Subject: [PATCH 508/878] perf: Optimize array_has() for array needle (#23337)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of https://github.com/apache/datafusion/issues/23334.

> The numbers below come from the committed criterion benchmark added in
https://github.com/apache/datafusion/pull/23335 (`cargo bench --bench
array_has`) — **origin** = the per-row `eq` kernel (unoptimized `main` /
https://github.com/apache/datafusion/pull/23335), **now** = with this
optimization applied. Run the bench on `main` and on this branch to
reproduce.

Full disclosure - this was heavily assisted by AI, and I did my best to
understand and justify every change here before submitting.

## Rationale for this change

`array_has(array, element)` returns, for each row, whether the array
contains the element.

When the `element` (needle) is an array rather than a scalar, the needle
argument is a column with one value per row, e.g. `array_has(t1.tags,
t2.key)` in a join filter, execution goes through
`array_has_dispatch_for_array` (the `ColumnarValue::Array` needle
branch), which compared each row by invoking the Arrow `eq` kernel once
per row.

That kernel allocates a `BooleanArray` and pays downcast and dispatch
overhead on every row. (The scalar-needle branch was optimized
separately in #20374.)

What this removes is the fixed per-row kernel overhead, not the element
comparison itself, so the gain is largest for short lists and shrinks as
lists grow.

All numbers below are from the committed criterion benchmark (`cargo
bench --bench array_has`, groups `array_has_array_null_patterns` /
`array_has_array_by_size` / `array_has_array_by_rows`): the `array_has`
UDF evaluated in isolation with an array needle, **origin** (the per-row
`eq` kernel) vs **now**. "list length" is the number of elements in each
row's array (not the row count). Not end-to-end query time.

### By data type and null pattern (list length 64, 10K rows)

| element | element len | null pattern | origin | now | speedup |

|-----------|----------------|----------------------|---------|---------|---------|
| i64 | - | no nulls, found | 1.10 ms | 73 µs | 15.1x |
| i64 | - | no nulls, not found | 1.07 ms | 72 µs. | 14.9x |
| i64 | - | 30% nulls, found | 1.17 ms | 315 µs | 3.7x |
| i64 | - | 30% nulls, not found | 1.10 ms | 274 µs | 4.0x |
| i64 | - | all null | 1.10 ms | 272 µs | 4.0x |
| i64 | - | collision | 1.10 ms | 270 µs | 4.1x |
| Utf8 | short (inline) | no nulls | 2.57 ms | 1.01 ms | 2.5x |
| Utf8 | short (inline) | 30% nulls | 3.37 ms | 1.52 ms | 2.2x |
| Utf8 | long (>12B) | no nulls | 2.61 ms | 1.04 ms | 2.5x |
| Utf8 | long (>12B) | 30% nulls | 3.31 ms | 1.52 ms | 2.2x |
| Utf8 | - | all null | 1.26 ms | 256 µs | 4.9x |
| LargeUtf8 | short (inline) | no nulls | 2.56 ms | 1.02 ms | 2.5x |
| LargeUtf8 | short (inline) | 30% nulls | 3.20 ms | 1.54 ms | 2.1x |
| LargeUtf8 | long (>12B) | no nulls | 2.67 ms | 1.05 ms | 2.6x |
| LargeUtf8 | long (>12B) | 30% nulls | 3.42 ms | 1.59 ms | 2.2x |
| LargeUtf8 | - | all null | 1.31 ms | 263 µs | 5.0x |
| Utf8View | short (inline) | no nulls | 1.18 ms | 239 µs | 4.9x |
| Utf8View | short (inline) | 30% nulls | 1.26 ms | 246 µs | 5.1x |
| Utf8View | long (>12B) | no nulls | 2.86 ms | 1.17 ms | 2.4x |
| Utf8View | long (>12B) | 30% nulls | 3.51 ms | 1.66 ms | 2.1x |
| Utf8View | - | all null | 1.20 ms | 267 µs | 4.5x |

The i64 null cases are uniform (~4x) whether the match is present,
absent, the whole list is null, or the needle collides with a null
slot's backing fill value — validity is folded in with one word-parallel
op, so there is no per-row rescan and no null slot can match.

Strings win ~2.1–2.5x mainly by dropping the per-row `BooleanArray`
allocation. `Utf8View` additionally uses a view-aware compare: the byte
length and 4-byte prefix packed into the 128-bit view reject non-matches
before touching the data buffer, and an inline value (≤ 12 bytes) is
matched by whole-view equality with no materialization at all — hence
~5x on short/inline strings. When long strings share a prefix (e.g.
ARNs) the prefix can't reject, so `Utf8View` falls in line with the
other string types (~2.1–2.4x). No string case regresses.

### By list length (i64, 30% element nulls, not found, 10K rows)

| elems/row | origin  | now     | speedup                              |
|-----------|---------|---------|--------------------------------------|
| 8         | 1.03 ms | 111 µs  | 9.3x                                 |
| 32        | 1.07 ms | 197 µs  | 5.5x                                 |
| 128       | 1.18 ms | 446 µs  | 2.6x                                 |
| 256       | 1.28 ms | 780 µs  | 1.6x                                 |
| 512       | 1.54 ms | 1.44 ms | 1.1x                                 |
| 1024      | 2.17 ms | 2.15 ms | 1.0x (falls back to per-row kernel)  |

The element-null branch makes a few passes over the values; past a
moderate average list length (`NULL_FAST_PATH_MAX_LEN`) the per-row
kernel wins, so it bails to it there — no meaningful regression. That
average is measured over the visible (sliced) region, so a sliced
array's hidden child elements can't route a small window to the slow
path. The all-valid fold has no such crossover.

### By row count (i64, 8 elems/row, 30% nulls, not found)

| rows | origin    | now      | speedup |
|------|-----------|----------|---------|

Invariant to the number of rows — the per-row overhead removed is a
fixed cost, so absolute savings scale linearly with the column height.

The remaining benchmarks in the suite (scalar `array_has`,
`array_has_all`, `array_has_any` — paths this PR does not touch) are
unchanged (median 0.99x, within measurement noise), confirming no
regression outside the array-needle path.

### End-to-end (context)

For a query dominated by an array-needle `array_has` join filter (a
`NestedLoopJoinExec` with `filter=array_has(tags, key)` over 3000x3000
rows of 8-element lists) total time drops from 0.95s to 0.059s (~16x,
identical results). For a workload where `array_has` is a smaller
fraction, e.g. the ~6% of profile that motivated this (see #18070 /
#18161, which fixed the join's deep-copy but left the per-row
`array_has` cost), the overall speedup is single-digit percent.

## What changes are included in this PR?

A fast path for primitive and string element types in
`array_has_dispatch_for_array`, preserving the Arrow `eq` kernel
semantics (total-order float equality; null elements never match):

- **All-valid elements:** each row is a single branchless OR-reduction
over the raw native value slice (auto-vectorizes; the common case).
- **Element nulls:** a null slot's backing value is arbitrary, so the
per-element equality bitmap is ANDed with the validity bitmap (one
word-parallel op, no per-element branch) before reducing each row to
"any bit set", a null slot can never match regardless of its value. This
branch is processed in row chunks so the scratch buffer stays bounded,
and past `NULL_FAST_PATH_MAX_LEN` average elements/row a length check
over the visible (sliced) region bails to the per-row kernel (see the
list-length table).
- **String elements:** each row is a single pass over the row's values
(compare, then consult validity only on a match). `Utf8View` compares
the packed 128-bit views directly — length + 4-byte prefix reject
non-matches before any data-buffer access, and an inline value (≤ 12
bytes) matches by whole-view equality with no materialization.
- **Nested (and any other) element types** keep using the per-row `eq`
kernel.

The array-needle benchmarks used for the numbers above are added in #3
(null patterns, list length, and row count).

## Are these changes tested?

Yes:

- New unit tests for the array-needle path covering element nulls, the
null-fill collision (needle equal to a null slot's backing value),
total-order float equality (`NaN` / `-0.0`), sliced arrays (including a
small visible window over a large backing child), `LargeList` offsets,
empty rows, a multi-chunk input, and a long-list input that exercises
the per-row fallback, each cross-checked against the original per-row
`eq` kernel as an oracle.
- Existing `array_has` / `array_contains` / `join_lists` sqllogictest
suites pass.

## Are there any user-facing changes?

No.

Subject: [PATCH 509/878] Allow Range partitioned inputs to PartitionedTopK
 (#23355)

## Which issue does this PR close?

- Closes #23290.

## What changes are included in this PR?

In two commits:

* Improve the robustness of `WindowTopN` to intermediate
`RepartitionExec` nodes, to ensure that `PartitionedTopK` can still be
used when `target_partitions` mismatches physical partitions.
* Use `required_input_distributions` to declare required partitioning
for `PartitionedTopKExec`, `BoundedWindowAggExec`, and `WindowAggExec`.

## Are these changes tested?

Yes, new `slt` tests are added for both the `WindowTopN` robustness fix,
and for the use of `required_input_distributions` in `PartitionedTopK`.

## Are there any user-facing changes?

No: only plan changes.

#23184 allowed compatible range-partitioned inputs to satisfy
partitioned inner joins without hash repartitioning. However, join
output still downgraded `Partitioning::Range` to `UnknownPartitioning`,
so downstream joins and aggregates could not reuse the preserved range
layout and inserted avoidable hash repartitions.

## What changes are included in this PR?

- Preserve `Partitioning::Range` in `adjust_right_output_partitioning`.
- Shift right-side range-ordering column indexes into the joined schema
while retaining split points and sort options.
- Add unit coverage for compound range keys and non-default sort
options.
- Update SQL logic test plans for nested range joins and a range join
feeding an aggregate.

## Are these changes tested?

Yes.

- `./dev/rust_lint.sh`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `cargo test -p datafusion-physical-plan
test_adjust_right_output_partitioning_preserves_range`
- `cargo test --profile=ci --test sqllogictests --
range_partitioning.slt`
- `ulimit -n 10240 && RUST_BACKTRACE=1 cargo test --profile ci --exclude
datafusion-examples --exclude datafusion-benchmarks --exclude
datafusion-cli --workspace --lib --tests --bins --features
avro,json,backtrace,extended_tests,recursive_protection,parquet_encryption`

## Are there any user-facing changes?

Yes. Physical plans can preserve proven range partitioning through
joins, allowing compatible downstream joins and aggregates to avoid
unnecessary hash repartitioning. There are no public API changes.

Subject: [PATCH 511/878] chore: Simplifying `SortPreservingMergeStream` to use
 generators instead of state machine (#23407)

## Which issue does this PR close?

- N/A

## Rationale for this change

I'm trying to make some Sort optimization but it is hard to get stuff
merged where the code is already complex even if adding a simple
optimization (like when only 1 stream is left just return those
batches).

This makes the code simpler as you can now read it in straight line flow
control, while not sacrificing performance

I did not use `RecordBatchReceiverStreamBuilder` since I want pull based
and not push based stream

## What changes are included in this PR?

Added `genawaiter` dependency, replace the SortPersevingMergeStream main
state machine loop with generator yield

## Are these changes tested?

existing tests

## Are there any user-facing changes?

no

-----

## Why not using `async-stream` crate from tokio?

**Why not using `async-stream` crate from tokio (that we already have
transitive dependency on) or other crates that are macro based.**

Because couple of reasons:
1. `cargo fmt` does not format macros body, so you manually need to
format and **validate** that the style is kept
2. more "magic" `yield` is not a function call
i. When you read the code, you cant go to definition of the `yield`
keyword since it is not a function
	ii. Cant put debugger on that keyword (from what I remember)
	iii. there is some hidden code that you need to
3. You can only use `yield` from the macro body (so you cant extract
functions with `yield` for example)

Subject: [PATCH 512/878] Enforce co-partitioning for sort merge and symmetric
 hash joins (#23480)

## Which issue does this PR close?

- Closes #23451
- Closes #23478
- Closes #23479

## Rationale for this change

Partition-index-aware joins require compatible input layouts. Compatible
Range layouts can satisfy that without repartitioning.

## What changes are included in this PR?

- Require co-partitioned children for sort-merge and partitioned
symmetric hash joins.
- Allow compatible Range inputs to satisfy those requirements.
- Let streaming tables declare output partitioning and preserve it
through scan projection.
- Add sanity checks and range-partitioning SLT coverage.

## Are these changes tested?

Yes

## Are there any user-facing changes?

Streaming table providers can declare output partitioning with
`StreamingTable::with_output_partitioning()`.

Subject: [PATCH 513/878] Infer placeholder type from ANY/ALL subquery, unit
 tests (#22545)

## Which issue does this PR close?

Closes #22475.

## Rationale for this change

`$1 = ANY (SELECT ...)` and `$1 <> ALL (SELECT ...)` left the
placeholder untyped because `infer_placeholder_types` had no arm for
`SetComparison`.

## What changes are included in this PR?

Adds the `SetComparison` arm to `infer_placeholder_types`, reading the
type from the subquery's projected column. Covers all quantifiers
(`ANY`, `ALL`) and comparison operators.

## How are these changes tested?

Unit tests for `ANY` and `ALL` placeholder inference, plus end-to-end
sqllogictests with `PREPARE`/`EXECUTE`.

## Are there any user-facing changes?

No.

Subject: [PATCH 514/878] Use `octet_length` for ClickBench Q27/Q28 byte-length
 semantics (#23475)

### Which issue does this PR close?

* Closes #23086

### Rationale for this change

ClickBench Q27 and Q28 are intended to aggregate the **byte length** of
string values, while DataFusion intentionally defines `length` as an
alias for `character_length`, which counts UTF-8 characters rather than
bytes. This change updates the in-repo ClickBench SQL to use
`octet_length(...)` explicitly, aligning these benchmark queries with
ClickBench's intended semantics without changing DataFusion's SQL
behavior.

### What changes are included in this PR?

* Updated ClickBench Q27 to use `AVG(octet_length("URL"))` instead of
`AVG(length("URL"))` in:

  * `benchmarks/queries/clickbench/queries/q27.sql`
  * `benchmarks/sql_benchmarks/clickbench/benchmarks/q27.benchmark`
* Updated ClickBench Q28 to use `AVG(octet_length("Referer"))` instead
of `AVG(length("Referer"))` in:

  * `benchmarks/queries/clickbench/queries/q28.sql`
  * `benchmarks/sql_benchmarks/clickbench/benchmarks/q28.benchmark`
* Updated the corresponding SQLLogicTest (`clickbench.slt`) queries and
expected `EXPLAIN` output so the logical and physical plans reference
`octet_length(...)` rather than `character_length(...)` or
`length(...)`.
* Added brief comments in the benchmark SQL noting that `length(...)` in
DataFusion counts characters and that `octet_length(...)` is used to
preserve ClickBench byte-length semantics.

### Are these changes tested?

The patch updates the expected SQLLogicTest
(`datafusion/sqllogictest/test_files/clickbench.slt`) output for Q27 and
Q28 to reflect the new `octet_length(...)` plans.

No test execution or benchmark results are included in this patch.
Performance was **not measured** as part of this change.

### Are there any user-facing changes?

There are no user-facing API or SQL semantic changes. This change only
updates the in-repo ClickBench benchmark queries and their corresponding
SQLLogicTest expectations to use explicit byte-length semantics.

### LLM-generated code disclosure

This PR includes LLM-generated code and comments. All LLM-generated
content has been manually reviewed.

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23010

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`try_pushdown_through_join`
(`datafusion/physical-plan/src/projection.rs`)
decided whether each projected join-output column belonged to the left
or right
child by comparing its output index against the left child's field count
(`join_table_borders`) — i.e. it assumed the join output is a plain
`left ++ right` concatenation.

That assumption does not hold for all join types. A `LeftMark` /
`RightMark`
join appends a synthetic `mark` boolean column that has `JoinSide::None`
and
originates from neither child, so reasoning from output position can
route the
`mark` column to the wrong child. This is the panic that #22902 worked
around by
**disabling** projection pushdown for `LeftMark` / `RightMark` in
`HashJoinExec`
and `NestedLoopJoinExec` — correct, but it left the helper reasoning
from output
position rather than from the join's actual output-origin contract.


## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Thread the join's output-origin metadata (`&[ColumnIndex]`, already
computed by
  `build_join_schema`) into `try_pushdown_through_join`.
- Replace the output-position split (`join_table_borders` +
  `index < left_field_count`) with grouping by `ColumnIndex.side`:
- `Left` / `Right` columns are collected per child using the
child-relative
    `ColumnIndex.index`;
- a `JoinSide::None` (synthetic, e.g. `mark`) column makes the pushdown
decline
(`Ok(None)`), so the projection is embedded into the join instead — no
panic,
    no mis-routing.
- Remove the `LeftMark | RightMark` bypass from
  `HashJoinExec::try_swapping_with_projection` and
  `NestedLoopJoinExec::try_swapping_with_projection`; they now call
  `try_pushdown_through_join` uniformly.
- The shared helpers used by cross / symmetric-hash / sort-merge join
pushdown
  (`new_join_children`, `join_table_borders`, `join_allows_pushdown`,
`update_join_on`, `update_join_filter`) keep their signatures. The
side-grouped
  path uses a new private `new_join_children_from_groups` and reuses
`update_join_on` / `update_join_filter` with a zero column-index offset
(the
  groups already carry child-relative indices).

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes.

- New `subquery.slt` cases place a subset/reordering projection over a
mark join
— hash `LeftMark` (`IN` under `OR`), negated mark (`NOT EXISTS` under
`OR`),
and nested-loop mark (non-equi correlated) — asserting both the query
result
  and the `EXPLAIN` plan shape.
- Existing coverage is preserved: `cargo test -p
datafusion-physical-plan
projection` (incl. the filter-pushdown and `join_table_borders` unit
tests),
  the join `*.slt` suite, and `subquery.slt` all pass.
- `cargo clippy -p datafusion-physical-plan -- -D warnings` and `cargo
fmt --all`
  are clean.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No behavior change: the produced physical plans are unchanged for the
supported
cases (mark joins keep falling back to the same embedded-projection plan
as
before, regular joins push down as before).

One signature change to a `pub` helper: `try_pushdown_through_join`
gains a
`column_indices: &[ColumnIndex]` parameter (all in-tree callers are
updated). If
the project treats this helper as part of the public API surface, please
add the
`api change` label.

Subject: [PATCH 517/878] fix: optimize_projections failure with struct-field
 join keys (#22903)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22895.

## Rationale for this change

Join-key extraction can add helper projections and change a child plan's
output schema. Some parent nodes cache their schema, so after the child
rewrite they can still expose stale fields. Later projection pruning
then uses the stale schema and fails with missing-column errors.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

- Refresh a parent schema only when a rewritten child reports an actual
schema change.
- Re-check whether the plan has subqueries before each rule, so plans
that are decorrelated by earlier rules can use the in-place path in the
same optimizer pass.
- Add regression coverage for the reported struct-field join-key
failures.
- Add a regression case for union output labels while union-to-filter
rewriting is enabled.
- Add a focused optimizer unit test for parent schema refresh after
child schema changes.
- Update one existing optimized-plan expectation. The new plan removes a
redundant dedup step; the surrounding semi joins already preserve
distinctness.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 518/878] fix: Handle potential overflow in internal state for
 `avg(decimal)` (#22714)

## Which issue does this PR close?

- Closes #22713.

## Rationale for this change

Fixes a bug with `avg` that currently prevents us from running TPC-DS
q1. I think that this issues is masked by Parquet because the current
implementations infers that columns as a Decimal128.

## What changes are included in this PR?

1. Mark Decimal32/64 as `R` in sqllogictest, like the bigger decimal
types, and fixes some tests that used `?`. (this can be a separate PR,
but its seems very small).
2. Adds a test for decimal32 overflow
3. `DecimalAvgAccumulator` now takes another type to hold its inner sum
accumulator, which can be different than the input/output type.
4. Decimal32, Decimal64 and Decimal256 use larger types to track the sum
in order to prevent an overflow
5. Adds some unit tests for the `AVG` impl building blocks.

## Are these changes tested?

Additional SLT test that would've overflowed internally, and more
focused unit tests for `AvgGroupsAccumulator`

## Are there any user-facing changes?

None, just more code that doesn't currently work and will work now.

Subject: [PATCH 519/878] fix: support type coercion for MAP literals with NULL
 values in VALUES lists (#23521)

## Which issue does this PR close?

- Closes #23474.

## Rationale for this change

A bare `MAP {'k1': NULL}` literal infers a `Null` value type, producing
`Map("entries": Struct("key": Utf8, "value": Null))`. Placing it in a
VALUES list alongside concretely-typed map rows failed with:

Error during planning: Inconsistent data type across values list at row
1 column 0.

This is because `type_union_resolution_coercion` (the pairwise worker
behind `type_union_resolution`, which the VALUES builder uses to widen
row types) had recursion arms for `Dictionary`, `RunEndEncoded`,
`Struct`, and `List` (via `list_coercion`), but none for `Map`. Scalar
NULL inference across a VALUES list (`VALUES (1), (NULL)`) already
worked; the same inference just never reached into a map's value type.
This gap was noted in #23406, where the tests had to use a `CAST(NULL AS
BIGINT)` workaround.

## What changes are included in this PR?

- A one-line fix in
`datafusion/expr-common/src/type_coercion/binary.rs`: wire the existing
`map_coercion` helper (already used by `comparison_coercion` and
`type_union_coercion`) into `type_union_resolution_coercion`'s fallback
chain. The recursion into the map's key/value types then applies the
exact same rules as scalar VALUES coercion (`null_coercion` for NULL
inference, `binary_numeric_coercion` for numeric widening),
symmetrically in either row order.
- A unit test (`test_type_union_resolution_map`) covering Null + Int64
value types in both orders, Int64 + Null + Float64 widening, and Map vs.
Struct still refusing to unify.
- A new "map NULL value coercion in VALUES" section in
`datafusion/sqllogictest/test_files/map.slt` covering: the issue
reproducer, the reversed row order, all-NULL values (resulting type
`Map("entries": Struct("key": Utf8, "value": Null))`, verified via
`arrow_typeof`), multi-key rows with one NULL value, NULL scattered
across three rows, numeric widening to Float64, two-level nested maps,
NULL round-tripping as NULL through `SELECT`, and `INSERT INTO ...
VALUES`.
- Incompatible concrete value types still error: `(MAP {'k': 1}), (MAP
{'k': 'hello'})` follows the scalar VALUES rule (coerce to the numeric
type, then fail with `Cast error: Cannot cast string 'hello' to value of
Int64 type`, which is the same behavior as `VALUES (1), ('hello')`).
- A note above the #23406 tests documenting that the `CAST(NULL AS
BIGINT)` workaround is no longer required (those tests are left
unchanged).

## Are these changes tested?

Yes. New unit test in `datafusion-expr-common` and new sqllogictests in
`map.slt` as described above. The full sqllogictest suite (492 files)
passes locally with zero regressions, as do `cargo test -p
datafusion-expr -p datafusion-expr-common`, `cargo fmt`, and `cargo
clippy --workspace --all-targets -- -D warnings`.

## Are there any user-facing changes?

`VALUES` lists (and other contexts that use `type_union_resolution`,
such as `CASE`/`COALESCE`/array literals) now unify Map types whose
key/value types are coercible, including bare NULL map values. No API
changes; previously failing queries now succeed, and incompatible-type
errors are preserved.

Subject: [PATCH 520/878] chore(deps): bump the codeql-actions group with 2
 updates (#23610)

Bumps the codeql-actions group with 2 updates:
[github/codeql-action/init](https://github.com/github/codeql-action) and
[github/codeql-action/analyze](https://github.com/github/codeql-action).

Updates `github/codeql-action/init` from 4.36.2 to 4.37.0

</ul>
<h2>4.35.5 - 15 May 2026</h2>
<ul>
<li>We have improved how the JavaScript bundles for the CodeQL Action
are generated to avoid duplication across bundles and reduce the size of
the repository by around 70%. This should have no effect on the runtime
behaviour of the CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3899">#3899</a></li>
<li>For performance and accuracy reasons, <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> will now only be enabled on a pull request when
diff-informed analysis is also enabled for that run. If diff-informed
analysis is unavailable (for example, because the PR diff ranges could
not be computed), the action will fall back to a full analysis. <a
href="https://redirect.github.com/github/codeql-action/pull/3791">#3791</a></li>
<li>If multiple inputs are provided for the GitHub-internal
<code>analysis-kinds</code> input, only <code>code-scanning</code> will
be enabled. The <code>analysis-kinds</code> input is experimental, for
GitHub-internal use only, and may change without notice at any time. <a
href="https://redirect.github.com/github/codeql-action/pull/3892">#3892</a></li>
<li>Added an experimental change which, when running a Code Scanning
analysis for a PR with <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> enabled, prefers CodeQL CLI versions that have
a cached overlay-base database for the configured languages. This speeds
up analysis for a repository when there is not yet a cached overlay-base
database for the latest CLI version. We expect to roll this change out
to everyone in May. <a
href="https://redirect.github.com/github/codeql-action/pull/3880">#3880</a></li>
</ul>
<h2>4.35.4 - 07 May 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.4">2.25.4</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3881">#3881</a></li>
</ul>
<h2>4.35.3 - 01 May 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.19.3 and earlier. These versions of
CodeQL were discontinued on 9 April 2026 alongside GitHub Enterprise
Server 3.15, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3837">#3837</a></li>
<li>Configurations for private registries that use Cloudsmith or GCP
OIDC are now accepted. <a
href="https://redirect.github.com/github/codeql-action/pull/3850">#3850</a></li>
<li>Best-effort connection tests for private registries now use
<code>GET</code> requests instead of <code>HEAD</code> for better
compatibility with various registry implementations. For NuGet feeds,
the test is now always performed against the service index. <a
href="https://redirect.github.com/github/codeql-action/pull/3853">#3853</a></li>
<li>Fixed a bug where two diagnostics produced within the same
millisecond could overwrite each other on disk, causing one of them to
be lost. <a
href="https://redirect.github.com/github/codeql-action/pull/3852">#3852</a></li>

page</a> for the relevant changes to the CodeQL CLI and language
packs.</p>
<h2>[UNRELEASED]</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.20.6 and earlier. These versions of
CodeQL were discontinued on 1 July 2026 alongside GitHub Enterprise
Server 3.16, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3956">#3956</a></li>
</ul>
<h2>4.37.0 - 08 Jul 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.0">2.26.0</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3995">#3995</a></li>
<li>In addition to the existing input format, the
<code>config-file</code> input for the <code>codeql-action/init</code>
step will soon support a new <code>[owner/]repo[@ref][:path]</code>
format. All components except the repository name are optional. If
omitted, <code>owner</code> defaults to the same owner as the repository
the analysis is running for, <code>ref</code> to <code>main</code>, and
<code>path</code> to <code>.github/codeql-action.yaml</code>. Support
for this format ships in this version of the CodeQL Action, but will
only be enabled over the coming weeks. <a

<h2>4.36.3 - 01 Jul 2026</h2>

<h2>4.36.2 - 04 Jun 2026</h2>
<ul>
<li>Cache CodeQL CLI version information across Actions steps. <a
href="https://redirect.github.com/github/codeql-action/pull/3943">#3943</a></li>
<li>Reduce requests while waiting for analysis processing by using
exponential backoff when polling SARIF processing status. <a

<h2>4.36.0 - 22 May 2026</h2>
<ul>
<li><em>Breaking change</em>: Bump the minimum required CodeQL bundle
version to 2.19.4. <a
href="https://redirect.github.com/github/codeql-action/pull/3894">#3894</a></li>
<li>Add support for SHA-256 Git object IDs. <a

<a
href="https://redirect.github.com/github/codeql-action/pull/3926">#3926</a></li>
</ul>
<h2>4.35.5 - 15 May 2026</h2>
<ul>
<li>We have improved how the JavaScript bundles for the CodeQL Action
are generated to avoid duplication across bundles and reduce the size of
the repository by around 70%. This should have no effect on the runtime
behaviour of the CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3899">#3899</a></li>
<li>For performance and accuracy reasons, <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> will now only be enabled on a pull request when
diff-informed analysis is also enabled for that run. If diff-informed
analysis is unavailable (for example, because the PR diff ranges could
not be computed), the action will fall back to a full analysis. <a
href="https://redirect.github.com/github/codeql-action/pull/3791">#3791</a></li>
<li>If multiple inputs are provided for the GitHub-internal
<code>analysis-kinds</code> input, only <code>code-scanning</code> will
be enabled. The <code>analysis-kinds</code> input is experimental, for
GitHub-internal use only, and may change without notice at any time. <a
href="https://redirect.github.com/github/codeql-action/pull/3892">#3892</a></li>
<li>Added an experimental change which, when running a Code Scanning
analysis for a PR with <a
href="https://redirect.github.com/github/roadmap/issues/1158">improved
incremental analysis</a> enabled, prefers CodeQL CLI versions that have
a cached overlay-base database for the configured languages. This speeds
up analysis for a repository when there is not yet a cached overlay-base
database for the latest CLI version. We expect to roll this change out
to everyone in May. <a
href="https://redirect.github.com/github/codeql-action/pull/3880">#3880</a></li>
</ul>
<h2>4.35.4 - 07 May 2026</h2>

customers using CodeQL version 2.19.3 and earlier. These versions of
CodeQL were discontinued on 9 April 2026 alongside GitHub Enterprise

CodeQL Action. <a

Subject: [PATCH 521/878] perf: optimize `trunc` for scalar precision case (10x
 faster) (#23593)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Optimize existing expression.

## What changes are included in this PR?

Added an array fast path for trunc(value, scalar precision) that hoists
10^precision out of the per-element loop and uses a unary kernel instead
of broadcasting the precision and recomputing powi per element.

## Are these changes tested?

Existing tests.

Benchmark (criterion):

- trunc f32 precision array_ 1024: 87.531% faster (base 1284ns -> cand
160ns)
- trunc f64 precision array_ 1024: 81.29% faster (base 1313ns -> cand
245ns)
- trunc f32 precision array_ 4096: 91.021% faster (base 4542ns -> cand
407ns)
- trunc f64 precision array_ 4096: 82.983% faster (base 4560ns -> cand
776ns)
- trunc f32 precision array_ 8192: 92.235% faster (base 9475ns -> cand
735ns)
- trunc f64 precision array_ 8192: 81.919% faster (base 10319ns -> cand
1865ns)

Full criterion output:

Subject: [PATCH 522/878] minor: validate config `recursion_limit` when setting
 it (#23592)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

Follows up to https://github.com/apache/datafusion/pull/23054

- Part of https://github.com/apache/datafusion/issues/17498

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Similar to #23054, 0 value in `recursion_limit` is invalid, and carrying
such value to the SQL parsing logic can cause bugs or panics. A better
alternative would be to catch the invalid `0` at config value setting
step.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
1. Use a safe type `ConfigNonZeroUsize` instead of `usize` for this
configuration
2. Propogate changes to the implementation
3. Add one `.slt` test

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
4. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 523/878] perf: optimize `upper` (6% faster) (#23588)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Optimize existing expression.

## What changes are included in this PR?

Stream uppercase char mapping directly into the string builder in the
non-ASCII case-conversion path, eliminating the per-row String heap
allocation and copy that str::to_uppercase incurred (lowercase left
unchanged for final-sigma correctness; Utf8View left unchanged to
preserve byte-identical layout).

## Are these changes tested?

Existing tests.

Benchmark (criterion):

- upper_unicode_utf8: 7.073% faster (base 325499ns -> cand 302477ns)
- upper_unicode_large_utf8: 6.065% faster (base 325116ns -> cand
305397ns)

Full criterion output:

```text
upper_unicode_utf8      time:   [302.60 µs 303.42 µs 304.22 µs]
                        change: [−7.2166% −7.0726% −6.9250%] (p = 0.00 < 0.05)
                        Performance has improved.

  14 (14.00%) high severe

                        time:   [305.90 µs 306.55 µs 307.12 µs]

                        Performance has improved.
Found 1 outliers among 100 measurements (1.00%)

Updates `regex` from 1.12.4 to 1.13.0
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/rust-lang/regex/blob/master/CHANGELOG.md">regex's
changelog</a>.</em></p>
<blockquote>
<h1>1.13.0 (2026-07-09)</h1>
<p>This release includes a new API, a <code>regex!</code> macro, for
lazy compilation of
a regex from a string literal. If you use regexes a lot, it's likely
you've
already written one exactly like it. The new macro can be used like
this:</p>
<pre lang="rust"><code>use regex::regex;
<p>fn is_match(line: &amp;str) -&gt; bool {<br />
// The regex will be compiled approximately once and reused
automatically.<br />
// This avoids the footgun of using <code>Regex::new</code> here, which
would<br />
// guarantee that it would be compiled every time this routine is
called.<br />
// This would likely make this routine much slower than it needs to
be.<br />
regex!(r&quot;bar|baz&quot;).is_match(line)<br />
}</p>
<p>let hay = &quot;<br />
path/to/foo:54:Blue Harvest<br />
path/to/bar:90:Something, Something, Something, Dark Side<br />
path/to/baz:3:It's a Trap!<br />
&quot;;</p>
<p>let matches = hay.lines().filter(|line| is_match(line)).count();<br
/>
assert_eq!(matches, 2);<br />
</code></pre></p>
<p>Improvements:</p>
<ul>
<li><a
href="https://redirect.github.com/rust-lang/regex/issues/709">#709</a>:
Add a new <code>regex!</code> macro for efficient and automatic reuse of
a compiled regex.</li>

Subject: [PATCH 525/878] Fix within group aggregates with unparser (#22195)

## Which issue does this PR close?

No issue, but a bug from production

## Rationale for this change

The unparser breaks a round trip on aggregates with a within group.

I.e,

```sql
SELECT approx_percentile_cont(0.9, 200) WITHIN GROUP (ORDER BY salary * 2 DESC) FROM person
```

Becomes:

```sql
SELECT approx_percentile_cont((person.salary * 2), 0.9, 200) WITHIN GROUP (ORDER BY (person.salary * 2) DESC NULLS FIRST) FROM person
```

This breaks things


## What changes are included in this PR?

Adds some structure to the unparser to basically unparse this correctly.

## Are these changes tested?

Yes, a few test cases added

## Are there any user-facing changes?

Nope

Subject: [PATCH 526/878] bench(sort): fix sort axis benchmark run on single
 partition (#23614)

## Which issue does this PR close?

N/A

## Rationale for this change

When I created the sort axis benchmarks I meant to only have single
partition without coalescing, so when we benchmark sorted input the
stream will get sorted input, but having coalesce partitions ruin that.

also added env var to control the run so we can pass this envs when
using the benchmark runner in github comments

## What changes are included in this PR?

use single partition and add env var controls + increase batch size for
sort axis and set runtime batch size based on the batches batch size

## Are these changes tested?

Manually

## Are there any user-facing changes?
No

Subject: [PATCH 527/878] perf: preallocate memory in `pad` (#23586)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23587.

## Rationale for this change

Performance optimisation in `lpad`/`rpad` UDF. Some codepaths do not
preallocate memory for the output string builder. Estimate capacity at
lower bound - works good for ASCII, slightly pessimistic for UTF8.

## What changes are included in this PR?

- Preallocate memory via `GenericStringBuilder::with_capacity`

## Are these changes tested?

- Bench shows significant improvement up to 65%
- Unit tests passed
- SLT passed

Subject: [PATCH 528/878] minor: validate config `max_spill_file_size_bytes`
 when setting it (#23594)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of https://github.com/apache/datafusion/issues/17498

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
This is logically the same change as #23592, but for another
configuration.

0 is an invalid setting here, it will cause every spill batch to create
a new file and cause inefficiencies.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 529/878] minor: validate config
 `soft_max_rows_per_output_file` when setting it (#23597)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of https://github.com/apache/datafusion/issues/17498

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
This is logically the same change as #23592, but for another
configuration.

0 is a invalid setting here, and such value might cause very large
output file count.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 532/878] minor: validate config
 `minimum_parallel_output_files` when setting it (#23596)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of https://github.com/apache/datafusion/issues/17498

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
This is logically the same change as #23592, but for another
configuration.

This value represents number of concurrent writer, and 0 is a invalid
value. So validate it must be non-zero

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 535/878] ci: reintroduce code coverage reporting with
 cargo-llvm-cov (#23336)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #3678.

## Rationale for this change
Code coverage has been disabled since #3678. The reason was it failed
because of sql_integration test binary. This PR reintroduces it

## What changes are included in this PR?
Reintroduce code coverage

## Are these changes tested?
I've been successfully make it work in my fork:
https://github.com/buraksenn/datafusion/pull/345
<img width="2134" height="746" alt="image"
src="https://github.com/user-attachments/assets/8e2c4e48-0cff-4ff9-9a46-1179a54c6945"
/>

I needed to add `CODECOV_TOKEN` as a secret variable to the fork.

You can check
https://github.com/apache/datafusion/pull/23336#issuecomment-4925329066
comment of codecov for successful run

## Are there any user-facing changes?
no

Subject: [PATCH 536/878] fix: handle interleaved HashJoin projections in sort
 pushdown (#23591)

## Which issue does this PR close?

- Closes #23590.

## Rationale for this change

Sort pushdown through a `HashJoinExec` with an embedded projection
assumed that all projected left-side columns formed a contiguous prefix.
That assumption is not valid when the projection interleaves columns
from the two join inputs.

For a `CollectLeft` right join projected as `[right.col_a,
left.nullable_col]`, a required sort on output column 1 was therefore
mistaken for a sort from the right child. The optimizer pushed a sort on
`right.col_a` below the join, and `SanityCheckPlan` rejected the
resulting plan because it did not satisfy the parent sort on
`left.nullable_col`.

## What changes are included in this PR?

- Determine whether required sort columns come from the right child by
inspecting each projected output column's `JoinSide`, instead of
comparing output positions with the number of projected left columns.
- Add a regression test with an interleaved hash join projection. The
test runs `SanityCheckPlan` and snapshots the valid optimized plan.

## Are these changes tested?

Yes.

- On unmodified `main`, the new regression test fails in
`SanityCheckPlan`: the right input is sorted by `col_a`, while the
parent requires `nullable_col`.
- With this change, the focused regression test passes.
- `cargo fmt --all`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `RUST_BACKTRACE=1 cargo test --profile ci --exclude
datafusion-examples --exclude datafusion-benchmarks --exclude
datafusion-cli --workspace --lib --tests --bins --features
avro,json,backtrace,extended_tests,recursive_protection,parquet_encryption`

## Are there any user-facing changes?

There are no API changes. Queries whose hash join projection interleaves
columns from both inputs no longer receive an invalid sort pushdown that
can fail physical-plan sanity checking.

Subject: [PATCH 537/878] fix: do not remove DISTINCT when a unique key was
 downgraded by a join (#23548)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23626.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

The `ReplaceDistinctWithAggregate` optimization pass was incorrectly
removing deduplication.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

First commit reproduces the bug in an SLT. I opted for SLT instead of a
test inside `datafusion/optimizer/src/replace_distinct_aggregate.rs`
since SLT seems easier to maintain. But let me know if you prefer the
test elsewhere.

Second commit fixes the bug. Also includes a drive-by documentation
change for `Dependency` to surface the field docs.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Yes

## Are there any user-facing changes?

Yes, query now deduplicates correctly

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

#22905 introduced explicit dictionary encoding preservation for
coercible function signatures, but dictionary inputs were still handled
differently across `TypeSignatureClass` variants:

| Signature category | Before | After |
| --- | --- | --- |
| `Native(...)` | Materialized by default; preserved when explicitly
requested | Same default/opt-in contract |
| Typed non-Native (e.g. `Integer`, `Numeric`, `Binary`) | Retained the
physical dictionary type by default | Materialized by default; preserved
when explicitly requested |
| `Any` | Passed through the original physical input type | Unchanged |

This PR makes the encoding preservation contract consistent across all
typed signature classes: coercion operates on the dictionary value type,
and the dictionary encoding is restored only when
`EncodingPreservation::dictionary()` is enabled.

An audit of the affected built-ins found two functions, Spark hex and
bitmap_count, that intentionally handle dictionary inputs; both now opt
in explicitly. Other affected functions generally expect materialized
value arrays, so the new default also avoids cases where signature
matching accepted a dictionary but the function implementation rejected
it at execution time. Functions that continue to materialize dictionary
inputs do not gain dictionary-aware execution efficiency yet, but they
can opt in later if they add support for encoded inputs.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Align dictionary coercion across typed signature classes and preserve
dictionary encoding when explicitly requested.
- Explicitly enable dictionary preservation for Spark `bitmap_count` and
the binary variant of Spark `hex`.
- Document the behavior change and migration guidance in the DataFusion
55.0.0 upgrade guide.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

- Unit tests cover materialization and preservation for Native,
non-Native, and `Any` inputs.
- SLTs cover `to_hex` materialization and verify that `bitmap_count`
preserves its dictionary input without an additional cast to `Binary`.
- Existing Spark `hex` dictionary tests cover its opt-in preservation
behavior.

## Are there any user-facing changes?

If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

This is a behavioral API change for UDFs using typed non-Native classes
such as `Integer` or `Binary`. UDFs relying on implicit dictionary
preservation must now enable `EncodingPreservation::dictionary()`
explicitly.

`TypeSignatureClass::Any` is unaffected. The upgrade guide has been
updated, and this PR should carry the `api change` label.

Subject: [PATCH 539/878] allow interleaveExec to support Range partioning
 (#23623)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- works towards #22395
- Closes #23455.

## Rationale for this change
see #23455
<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?
The goal of this PR is to allow range partitioning to propagate through
`InterleaveExec`. Updated `can_interleave()` to accept
`Partitioning::Range` when all children share an identical
RangePartitioning (same ordering and split points), matching the
existing behavior for `Partitioning::Hash`.

Updated `range_partitioning.slt` to expect InterleaveExec where it
previously expected UnionExec, since `can_interleave()` now accepts
Partitioning::Range.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?
yes, the `range_partioning.slt` file as well as the `union.slt` file sql
logic test. This PR also includes three test.
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?
physical plans may look different now.
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 540/878] fix: preserve aggregate scope when unparsing (#23327)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23317.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->


The unparser can fold a Projection into its Aggregate and then keep
walking into the Aggregate input. When that input is another Aggregate
or an unnamed derived Projection, the generated SQL moved references
above the SELECT block that defined them. Optimizer aliases such as
`group_alias_0` and base-table qualifiers such as `c.signup_date` were
no longer in scope.

Stop crossing those scope boundaries blindly. Render nested aggregate
inputs as derived relations, and when an aggregate reads from a derived
Projection, rewrite only input-schema columns to the derived output
names before rendering SELECT and GROUP BY expressions.
## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it

Yes

## Are there any user-facing changes?

<!--

updated before approving the PR.

Subject: [PATCH 541/878] feat: benchmark_runner, improve `--list`, optional
 `DATA_DIR` (#23354)

## Which issue does this PR close?

- Part of #21937, followup on PR feedback for #23052

## Rationale for this change

Code cleanup, usability improvements. Added `--list` argument, DATA_DIR
should now be properly inferred to the expected default if it's not
provided.

## What changes are included in this PR?

benchmark tool update only.

## Are these changes tested?

Yes.

## Are there any user-facing changes?

No.

Subject: [PATCH 542/878] fix: preserve EmptyExec and PlaceholderRowExec
 partition count across proto round-trip (#23643)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23642.

## Rationale for this change

`EmptyExecNode` and `PlaceholderRowExecNode` encoded only a schema, so
the partition count set by `EmptyExec::with_partitions(n)` was silently
lost across a physical-plan round-trip: a plan reporting `n` partitions
before serialization reported `1` after.

This is silent data loss rather than an error — the decoded plan is
well-formed but describes a different plan than the one encoded. It
bites any setup that plans in one process and executes in another. In
Ballista, an optimizer rule collapses provably-empty sub-plans into an
`EmptyExec` inheriting the replaced node's partition count; the
scheduler sizes the stage's task count from that count, ships the plan
to an executor, and every task above partition 0 fails with:

```
Internal("Assertion failed: partition < self.partitions: EmptyExec invalid partition 1 (expected less than 1)")
```

## What changes are included in this PR?

- Add a `uint32 partitions` field to `EmptyExecNode` and
`PlaceholderRowExecNode` in `datafusion.proto`, and regenerate the
prost/pbjson code via `regen.sh`.
- Write `partitions` on encode and apply it via `with_partitions(...)`
on decode.

Both `EmptyExec` and `PlaceholderRowExec` mirror their private
`partitions` field into `PlanProperties` as `UnknownPartitioning(n)`, so
the encoder reads the count via
`properties().output_partitioning().partition_count()` on the existing
`ExecutionPlan` trait. No new public API is added to
`datafusion-physical-plan`.

The wire format stays compatible in both directions. Plans encoded
before this field existed carry no value for it, which prost surfaces as
`0`; decode maps that to the previous default of `1`. Plans encoded
after this change add a field that older readers skip.

Note for #23501, which migrates these nodes to the `try_to_proto` /
`try_from_proto` pattern: that issue specifies "schema only" and a
byte-for-byte identical wire format, which would reintroduce this bug.
The `partitions` field should be folded into that rewrite.

## Are these changes tested?

Yes, three new tests in `roundtrip_physical_plan.rs`: partition-count
round-trips for `EmptyExec` and `PlaceholderRowExec`, plus one decoding
`partitions: 0` nodes directly to pin the backward-compatibility
mapping. The round-trip tests were confirmed to fail against the unfixed
decoder with exactly the reported symptom (4 partitions decoding to 1).

## Are there any user-facing changes?

No API changes to `datafusion-physical-plan`. Encoded plans gain a new
protobuf field, which is backward and forward compatible as described
above. The generated `EmptyExecNode` and `PlaceholderRowExecNode`
structs gain a `partitions` field, which breaks downstream code
constructing them with an exhaustive struct literal; this is documented
in the 55.0.0 upgrade guide.

+### `EmptyExecNode` and `PlaceholderRowExecNode` gained a `partitions` field
+
+The generated protobuf structs `EmptyExecNode` and `PlaceholderRowExecNode`
+encoded only a schema, so the partition count set by `EmptyExec::with_partitions`
+was silently dropped when a physical plan was serialized and deserialized: a plan
+that reported `n` partitions before encoding reported `1` after. Both messages now
+carry a `partitions` field that round-trips the count.
+
+**Who is affected:**
+
+- Users constructing `EmptyExecNode` or `PlaceholderRowExecNode` with an
+  exhaustive struct literal.
+
+**Migration guide:**
+
+Set the new field, or fill it from `Default`:
+
+```rust,ignore
+// Before
+EmptyExecNode { schema: Some(schema) }
+
+// After
+EmptyExecNode { schema: Some(schema), partitions: 4 }
+// or
+EmptyExecNode { schema: Some(schema), ..Default::default() }
+```
+
+The wire format stays compatible in both directions. Plans encoded before this
+field existed decode as a single partition, the previous default, and plans
+encoded after it add a field that older readers ignore.
+
+See [PR #23643](https://github.com/apache/datafusion/pull/23643) for details.

Subject: [PATCH 544/878] Resolve lost wakeup in SpillPoolReader with multiple
 concurrent SpillPoolWriters (#23522)

## Which issue does this PR close?

- Closes #23447

## Rationale for this change

When multiple `SpillPoolWriter` clones concurrently push batches to the
same channel, more than one non-finished `SpillFile` can be in flight.
This happens because each `SpillPoolWriter` clone takes the
`current_write_file` at the start of `push_batch` and puts it back when
it's done. When multiple `push_batch` calls happen concurrently, only
the first one will be able to take the `current_write_file` and the
others will all create their own new spill file. Which one gets put back
for subsequent use is a race condition.

If this occurred and the writers are all dropped before rotation happens
in, multiple files in the `files` deque will be have `writer_finished ==
false`. The last writer drop logic in `SpillPoolWriter::drop` only
finishes whatever file is the `current_write_file` as finished.

This can lead to a stalled situation when `SpillPoolFile::poll_next`
catches up with the writer and returns `Pending` because
`writer_finished == false`. A waker for the file is registered, but
since the last writer drop logic only finishes and wakes whatever
happens to be `current_write_file`, which may not be the current read
file, the waker may end up never being notified.

There is a secondary waker that is registered on the spill pool itself,
but due to fine grained locking, it is possible for the wake call in the
last writer drop logic to be called before the waker registration.

## What changes are included in this PR?

- Add support for tracking multiple unfinished write files
- Close all unfinished write files when the last writer is dropped
- Removed `writer_dropped` field which was an unnecessary
denormalisation of `active_writer_count == 0`

An additional benefit of tracking all unfinished write files is that
excessive creation of tiny spill files is avoided when many writers are
pushing batches concurrently.

## Are these changes tested?

Reproduction case from linked issue was used to confirm fix

## Are there any user-facing changes?

No

Subject: [PATCH 546/878] perf: optimize `replace` (2x faster) (#23589)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

## What changes are included in this PR?

Added a scalar from/to fast path to string `replace` that hoists a
memmem::Finder out of the per-row loop and skips materializing scalar
args into N-element arrays, avoiding per-row searcher construction for
the common replace(col,'lit','lit') pattern.

## Are these changes tested?

Existing tests + new unit tests.

Benchmark (criterion):

- replace_scalar from=_ab_ [size=8192, str_len=64]: 58.573% faster (base
226815ns -> cand 93963ns)
- replace_scalar from=_the_ [size=8192, str_len=16]: 30.039% faster
(base 155601ns -> cand 108860ns)
- replace_scalar from=_ab_ [size=8192, str_len=32]: 50.571% faster (base
174020ns -> cand 86017ns)
- replace_scalar from=_ab_ [size=8192, str_len=16]: 10.673% faster (base
135489ns -> cand 121028ns)
- replace_scalar from=_the_ [size=8192, str_len=32]: 52.7% faster (base
184286ns -> cand 87167ns)
- replace_scalar from=_the_ [size=8192, str_len=64]: 60.147% faster
(base 227922ns -> cand 90834ns)

Subject: [PATCH 547/878] fix: keep null-aware anti-join NULLs in the pushed
 dynamic filter (#23104)

## Which issue does this close?

Closes #23103.

## Rationale for this change

A hash join pushes a build-side dynamic filter (`key IN build_keys`)
down to the probe scan. For a null-aware anti join (`NOT IN`), that
filter drops the probe's NULL rows. But `NOT IN` three-valued logic
needs a probe-side NULL to collapse the whole result to zero rows. With
the NULL filtered away at the scan, before the join's null-aware check
runs, the join returns rows that shouldn't be there.

## What changes are included in this PR?

`SharedBuildAccumulator::build_filter` now ORs `probe_key IS NULL` into
the pushed predicate when the join is `null_aware`. Non-NULL probe rows
still get filtered, so the optimization stays. `HashJoinExec`'s
`null_aware` validation already guarantees a single probe key.

## Are these changes tested?

Yes. Added a parquet-backed case to `null_aware_anti_join.slt`. The
existing cases use in-memory `VALUES`, whose scans never apply the
pushed filter, so they passed despite the bug. The new one sets
`parquet.pushdown_filters = true` so the filter runs row-level. Without
the fix it returns `1, 3`; with it, zero rows.

## Are there any user-facing changes?

A `NOT IN` over a NULL-bearing inner now returns zero rows instead of
leaking rows, when join dynamic filter pushdown and row-level scan
filtering are both on.

Subject: [PATCH 548/878] chore: deprecate record_batch macro in favor of
 upstream one (#23295)

## Which issue does this PR close?

- Closes #13037.

## Rationale for this change
This was a long standing thing in the backlog. record_batch! was added
in arrow; however, it did not support vectors. Then I've created a PR in
arrow a while ago https://github.com/apache/arrow-rs/pull/9522. Once
that was released this macro can be deprecated

## What changes are included in this PR?
Mark record_batch! macro deprecated and use arrow one in relevant
places.

## Are these changes tested?
Yes

## Are there any user-facing changes?
Users will see a deprecation notice if they are using this macro

Subject: [PATCH 549/878] Support UDTFs in information_schema.routines / SHOW
 FUNCTIONS (#23438)

# Which issue does this PR close?

- Closes #23437.

# Rationale for this change

`information_schema.routines` and `SHOW FUNCTIONS` currently enumerate
only scalar / aggregate / window UDFs. Table functions (UDTFs)
registered via `SessionContext::register_udtf` are omitted, making them
undiscoverable through SQL. Discovery matters because downstream tooling
(DataFusion CLI, Massive's atlas SQL surface, dbt-datafusion, etc.) uses
these SQL surfaces to list available functions.

# What changes are included in this PR?

**1. Snapshot table functions into the information_schema provider.**

`Session::table_functions()` cannot exist on the `Session` trait today:
`TableFunction` lives in `datafusion-catalog`, which already depends on
`datafusion-session` (both `TableProvider::scan` and `TableFunction`
take `&dyn Session`). Adding a trait method returning `&HashMap<String,
Arc<TableFunction>>` would reverse that edge and create a
crate-dependency cycle. `ScalarUDF` / `AggregateUDF` / `WindowUDF` don't
hit this because they live in `datafusion-expr`, which sits below
`datafusion-session`.

This is the same underlying constraint as #23348. A follow-up PR will
move `TableFunction` (or hoist the relevant traits) so the builder can
be deleted.

For this PR, `SessionState.table_functions` is snapshotted into
`InformationSchemaProvider` via `with_table_functions()` at
construction. The provider is built per-query, so the snapshot stays
fresh.

**2. Emit UDTF rows in `information_schema.routines` only.**

`make_routines`: one row per UDTF with `routine_type = "FUNCTION"`,
`function_type = "TABLE"`, `data_type = "TABLE"`.

UDTFs deliberately do NOT appear in `information_schema.parameters`. A
same-named scalar UDF (e.g. `generate_series` exists as both a scalar
UDF in `functions-nested` and a UDTF in `functions-table`) would
cross-join with a UDTF row keyed only by (name, rid) and produce
spurious `TABLE`-typed variants of every scalar signature in `SHOW
FUNCTIONS`.

**3. Rewrite the `SHOW FUNCTIONS` SQL to UNION UDTFs directly from
`routines`.**

The old query joined `parameters p (INNER)` requiring both IN and OUT
rows before joining `routines`. UDTFs have no IN parameters, so they
fell out. The new plan sources scalar / aggregate / window signatures
from `parameters` as before, and UDTFs from a separate `UNION` branch
that reads `routines` directly (guarded by `function_type = TABLE`).
This avoids the cross-join blowup mentioned above.

# Are these changes tested?

Verified locally by registering a UDTF and running `SHOW FUNCTIONS`:

```
> SHOW FUNCTIONS LIKE 'stale%'
+---------------+-------------+---------------+
| function_name | return_type | function_type |
| stale_files   | TABLE       | TABLE         |
+---------------+-------------+---------------+
```

Happy to add sqllogictests in
`datafusion/sqllogictest/test_files/information_schema.slt` if
maintainers prefer.

# Are there any user-facing changes?

Yes: `SHOW FUNCTIONS` output now includes table functions.
`information_schema.routines` gains one row per registered UDTF.
`information_schema.parameters` is intentionally unchanged (see
rationale in point 2 above). Existing rows are unchanged.

Subject: [PATCH 550/878] Handle nulls in type coercion of higher-order UDFs,
 map_extract, spark array_repeat (#23071)

## Which issue does this PR close?

- Closes #23068 .

## Rationale for this change

Unresolved lambda variables and unspecified placeholders report a
`DataType::Null` data type, which causes an error when used as argument
of a function that doesn't handle nulls during type coercion

## What changes are included in this PR?

Handle null in `coerce_single_list_arg` for higher-order functions,
`map_extract` and in spark `array_repeat`. All other functions (scalar,
window, agg and higher-order) that uses user defined type coercion have
been checked to currently handle null args.

## Are these changes tested?

Test passing `array_filter` with an unresolved lambda variable to
`Dataframe::with_column` (which indirectly calls
`value_fields_with_higher_order_udf_and_lambdas` coercion via
`Projection::try_new`, `projection_schema`, `exprlist_to_fields`,
`Expr::to_field` ), and sqllogictests

## Are there any user-facing changes?

No

Subject: [PATCH 551/878] feat: Support Struct type in approx_distinct (#23663)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Relates to https://github.com/apache/datafusion/issues/22989 but does
not close it. More types are coming.


## Rationale for this change

- Support the Arrow type `Struct` type for `approx_distinct`

## What changes are included in this PR?

- Enable `HLLAccumulator` and `HllGroupsAccumulator` to support `Struct`
- Tests for the non-grouped and grouped path as part of `aggregate.slt`

## Are these changes tested?

Yes and  results are compared to DuckDB:

```sql
D CREATE TABLE approx_distinct_struct_test AS SELECT * FROM (VALUES
    (1, {'a': 1, 'b': 2}), (1, {'a': 1, 'b': 2}), (1, {'a': 3, 'b': 3}),
    (2, {'a': 4, 'b': 4}), (2, NULL),
    (3, NULL), (3, NULL),
    (4, {'a': 5, 'b': 5})
  ) AS t(g, s);

D SELECT approx_count_distinct(s) FROM approx_distinct_struct_test WHERE g = 1;
┌──────────────────────────┐
│ approx_count_distinct(s) │
│          int64           │
├──────────────────────────┤
│            2             │
└──────────────────────────┘
D SELECT g, approx_count_distinct(s) FROM approx_distinct_struct_test GROUP BY g ORDER BY g;
┌───────┬──────────────────────────┐
│   g   │ approx_count_distinct(s) │
│ int32 │          int64           │
├───────┼──────────────────────────┤
│     1 │                        2 │
│     2 │                        1 │
│     3 │                        0 │
│     4 │                        1 │
└───────┴──────────────────────────┘
D SELECT approx_count_distinct(s) FROM approx_distinct_struct_test;
┌──────────────────────────┐
│ approx_count_distinct(s) │
│          int64           │
├──────────────────────────┤
│            4             │
└──────────────────────────┘

```

## Are there any user-facing changes?

Yes, `approx_distinct` supports now `Struct` but no breaking changes.

## Which issue does this PR close?

- Closes #22265
- Closes #22255

## Rationale for this change

`time + interval` (and `interval + time` / `time - interval`) returned
an `Interval` instead of a `time`, so the value was never wrapped within
the 24-hour clock:

```
> SELECT time '23:30' + interval '2 hours';
25 hours 30 mins   -- an Interval, not a time
```

PostgreSQL (and DuckDB) return a `time` that wraps around midnight:

```
01:30:00
```

The root cause is in type coercion: `time <op> interval` was coerced by
widening the `time` operand into an `Interval`, so the addition happened
between two intervals and the result kept the `Interval` type.

## What changes are included in this PR?

Following the existing `Date - Date` special case (in the same two
files), `time ± interval` is now handled explicitly:

- **Coercion** (`expr-common/src/type_coercion/binary.rs`): `time +
interval`, `interval + time`, and `time - interval` now coerce to
`(time, interval)` — the interval normalized to `MonthDayNano`, and the
time operand kept at its own unit, which is also the result type.
`interval - time`, which is not meaningful, is left unchanged.
- **Evaluation** (`physical-expr/src/expressions/binary.rs`): a new
`apply_time_interval` adds/subtracts the interval's sub-day component
and wraps the result modulo 24 hours, for all four time units
(`Time32(Second|Millisecond)`, `Time64(Microsecond|Nanosecond)`) and
both operand orders. The result **keeps the input time's unit**,
mirroring `timestamp/date + interval` (which preserve their unit and
apply the interval at that resolution); interval precision finer than
the time's unit is truncated, so `time(s) + interval '1 nanosecond'` is
a no-op, exactly like `timestamp(s) + interval '1 nanosecond'`. Only the
interval's sub-day portion affects a time-of-day; whole months and days
are ignored, matching PostgreSQL (e.g. `time '10:00' + interval '1 day 2
hours'` = `12:00:00`).

`time - time` (→ `Interval`) is unchanged.

## Are these changes tested?

Yes.
`datafusion/sqllogictest/test_files/datetime/arith_time_interval.slt`
was previously a characterization test that documented the incorrect
`Interval` output; it now asserts the correct wrapped `time` results —
including wrapping past midnight in both directions (`22:00 + 3h →
01:00:00`, `02:00 - 3h → 23:00:00`), ignoring whole days, preserving
each input time unit (`arrow_typeof` per unit), and the finer-than-unit
interval truncation.

## Are there any user-facing changes?

Yes — `time ± interval` now returns a `time` value (wrapped within 24
hours) instead of an `Interval`, aligning DataFusion with PostgreSQL and
DuckDB. The result keeps the input time's unit rather than widening it
(see the 55.0.0 upgrade guide).

+### `time ± interval` now returns a `time` instead of an `interval`
+
+Adding or subtracting an `interval` to/from a `time` value now returns a `time`
+that wraps within the 24-hour clock, matching PostgreSQL and DuckDB. Previously
+DataFusion returned an `interval`.
+
+```sql
+-- 55.0.0 onwards: returns a time
+SELECT time '23:30:00' + interval '2 hours';
+-- 01:30:00
+```
+
+Only the sub-day portion of the interval affects the result; whole days and
+months are ignored, as in PostgreSQL. The result keeps the input time's unit
+(mirroring `timestamp + interval`), and any interval precision finer than that
+unit is truncated -- so `time(s) + interval '1 nanosecond'` is a no-op.

Subject: [PATCH 555/878] perf: optimize `regexp_match` for literal pattern
 usage (20% faster) (#23547)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Optimize existing expressions

## What changes are included in this PR?

Pass a literal regexp pattern/flags to arrow's kernel as scalar Datums
so the regex is compiled once per batch, instead of expanding the
literal to a full array and forcing a per-row HashMap<String, Regex>
cache lookup (plus a per-row format! allocation when flags are present).

## Are these changes tested?

Existing tests + new unit tests.

Benchmark (criterion):

- regexp_match_1000 literal pattern utf8view: 21.394% faster (base
249069ns -> cand 195784ns)
- regexp_match_1000 pattern array: 2.996% faster (base 190020ns -> cand
184327ns)
- regexp_match_1000 literal pattern: 23.964% faster (base 261795ns ->
cand 199059ns)
- regexp_match_1000 literal pattern and flags: 37.227% faster (base
280047ns -> cand 175794ns)

Subject: [PATCH 556/878] perf: avoid per-row copy in Spark hex byte encoding
 (#23473)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

The Spark `hex` function's byte-encoding path (`hex_encode_bytes`)
filled a reusable per-row `Vec` and then copied it into a
`StringBuilder` for every row. Since each input byte maps to exactly two
hex characters, the output can be written once directly into a single
value buffer, eliminating the per-row copy.

## What changes are included in this PR?

Rewrote `hex_encode_bytes` to write hex digits directly into one growing
value buffer with manually-tracked offsets and a `NullBufferBuilder`,
constructing the `StringArray` via `new_unchecked` (the buffer contains
only ASCII hex digits, so the existing no-validation behavior is
preserved). The 256-entry lookup table and all other hex paths are
unchanged.

## Are these changes tested?

Existing tests (`function::math::hex`) pass unchanged.

Benchmark (`datafusion/spark/benches/hex.rs`):

- hex_binary/1024·4096·8192: ~13.8% / 14.3% / 13.9% faster
- hex_utf8/1024·4096·8192: ~14.1% / 14.9% / 15.0% faster

## Are there any user-facing changes?

No

Subject: [PATCH 557/878] Add ExecutionPlan try_to_proto / try_from_proto hooks
 + ProjectionExec reference (#23495)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #23494.

## Rationale for this change

This is the foundation for porting `ExecutionPlan` serialization off the
central `downcast_ref` chain in
`datafusion/proto/src/physical_plan/mod.rs`, mirroring what #21929 did
for `PhysicalExpr` (tracked in #22418). Everything else in #23494
depends on this PR; it can't be parallelized because it defines the ctx
API and wiring that every per-plan follow-up uses.

## What changes are included in this PR?

In `datafusion-physical-plan` (feature-gated `#[cfg(feature =
"proto")]`):

- `ExecutionPlan::try_to_proto(&self, ctx: &ExecutionPlanEncodeCtx) ->
Result<Option<PhysicalPlanNode>>` — a new trait method defaulting to
`Ok(None)` (so un-migrated plans are unchanged).
- `ExecutionPlanEncodeCtx` / `ExecutionPlanDecodeCtx` plus the internal
`ExecutionPlanEncode` / `ExecutionPlanDecode` dispatch traits (defined
here, implemented in `datafusion-proto`) — the same dependency-inversion
the `PhysicalExpr` ctx uses. The ctx exposes
`encode_child`/`decode_child` (+ `_children`),
`encode_expr`/`decode_expr`, and typed **bytes-only**
`encode_udaf`/`decode_udaf` (+ udf/udwf) for function-carrying plans. No
proto type is ever named by physical-plan beyond the pure prost types in
`datafusion-proto-models`.
- An `expect_plan_variant!` macro mirroring `expect_expr_variant!`.

In `datafusion-proto`:

- `ConverterPlanEncoder` / `ConverterPlanDecoder` implement the dispatch
traits over the existing `PhysicalExtensionCodec` + converter (the
function serde reuses today's `fun_definition` byte semantics exactly).
The encode dispatch resolves `downcast_delegate()` first (so wrapper
plans serialize as their delegate, exactly like the `downcast_ref` chain
sees them), then calls the hook, then falls back to the existing
downcast chain.

`ProjectionExec` is migrated as the reference implementation: its old
encode arm is deleted and its decode arm reduced to
`ProjectionExec::try_from_proto`, so a green roundtrip proves the hook
is the only path.

## Are these changes tested?

Yes — the existing `proto_integration` roundtrip suite (including TPC-H)
passes unchanged, which exercises the `ProjectionExec` migration
end-to-end, plus a new test asserting that a wrapper plan delegating its
downcast identity to `ProjectionExec` still serializes as a projection
through the hook (it fails without the `downcast_delegate()`
resolution). The bytes-only function serde and the required-field decode
helpers — which have no in-tree plan caller until the function-carrying
plans migrate — are pinned by dedicated unit tests (payload semantics,
decode lookup order, error paths), addressing the patch-coverage gap.
`cargo clippy --all-targets -- -D warnings`, `cargo fmt`, and
`RUSTDOCFLAGS="-D warnings" cargo doc` are clean.

## Are there any user-facing changes?

New public API: the `try_to_proto` trait method (with a default, so
existing `ExecutionPlan` impls are unaffected) and the ctx types. No
wire-format change.

No API is removed: per the [API health
policy](https://datafusion.apache.org/contributor-guide/api-health.html),
the two per-plan `PhysicalPlanNodeExt` methods this migration replaces
(`try_into_projection_physical_plan` / `try_from_projection_exec`) are
kept with their original bodies under `#[deprecated(since = "55.0.0")]`.
(They were also never released: `PhysicalPlanNodeExt` was introduced by
#21929 after 54.0.0 shipped.) The per-plan follow-ups in #23494 will
deprecate their corresponding methods the same way, with removal after
the policy window.

+//! Serialization hooks for [`ExecutionPlan`], mirroring the
+//! `try_to_proto`/`try_from_proto` pattern used for `PhysicalExpr`.
+//!
+//! # Why the indirection
+//!
+//! An `ExecutionPlan` must be able to (de)serialize its child plans and its
+//! child physical expressions recursively. The concrete recursion lives in
+//! `datafusion-proto` (it owns the extension codec, the session context and the
+//! central converter), but `datafusion-proto` sits *above* `datafusion-physical-plan`
+//! in the crate graph. To let a plan drive that recursion without a dependency
+//! cycle, this module defines:
+//!
+//! * [`ExecutionPlanEncodeCtx`] / [`ExecutionPlanDecodeCtx`] — the stable,
+//!   concrete context types a plan author interacts with. New capabilities can
+//!   be added here without changing every plan's hook signature.
+//! * [`ExecutionPlanEncode`] / [`ExecutionPlanDecode`] — internal dispatch
+//!   traits, *defined* here but *implemented* in `datafusion-proto`, that the
+//!   context types delegate to. This is the dependency inversion that keeps the
+//!   proto types flowing in one direction only.
+//!
+//! `datafusion-physical-plan` depends on the pure prost types in
+//! `datafusion-proto-models` (feature `proto`), never on `datafusion-proto`.
+//!
+//! # Function-carrying plans
+//!
+//! Plans that reference UD(A/W)Fs (`AggregateExec`, the window execs, …) also
+//! ride the hook: the context exposes typed, *bytes-only* function serde —
+//! [`encode_udaf`](ExecutionPlanEncodeCtx::encode_udaf) /
+//! [`decode_udaf`](ExecutionPlanDecodeCtx::decode_udaf) and the udf/udwf
+//! siblings. These take/return `datafusion-expr` types plus `Vec<u8>` and never
+//! name a proto type, so the `PhysicalExtensionCodec` (which only
+//! `datafusion-proto` can name) stays fully encapsulated behind the adapter that
+//! backs these traits. The lookup-order policy (payload → codec; else registry →
+//! codec fallback) lives once, in that adapter, rather than in every plan.
+//!
+//! This is possible because `datafusion-physical-plan` sits *above*
+//! `datafusion-expr` in the crate graph; the expression-side ctx (in
+//! `physical-expr-common`, *below* `datafusion-expr`) cannot do this, which is
+//! why `ScalarFunctionExpr` remains special-cased there.

Subject: [PATCH 559/878] bench: add FixedSizeBinary coverage to multi_group_by
 benchmark (#23650)

## Which issue does this PR close?

- Related to #23646
- Related to #23645.

## Rationale for this change

The point of a specialized FixedSizeBinary group values is performance
but we have no performance benchmark for it.

## What changes are included in this PR?

Adds a `fixed_size_binary` experiment to
`datafusion/physical-plan/benches/multi_group_by.rs`
Run with:

```bash
cargo bench -p datafusion-physical-plan --bench multi_group_by --features test_utils -- fixed_size_binary
```
## Are these changes tested?

This is benchmark-only. The benchmark compiles on `main` and runs
end-to-end
on top of #23646. No product code changes.

## Are there any user-facing changes?

No.

Subject: [PATCH 560/878] test: Fix malformed `regexp_instr` error tests and
 add slt coverage (#23620)

## Which issue does this PR close?

N/A (found while reviewing test coverage for #23540)

## Rationale for this change

While checking `cargo llvm-cov` coverage of `regexp_instr`, I found that
the two `statement error` tests for `start < 1` in `regexp_instr.slt`
never actually exercise the start validation.

Coverage also showed two paths of `regexp_instr` untested anywhere:

- the `N must be 1 or greater` error for `nth < 1`
- looking up an already-compiled regex from the per-batch cache when the
pattern column returns to a previously seen pattern (e.g. `['abc',
'def', 'abc']`). This path becomes more important with the memoization
added in #23540.

## What changes are included in this PR?

- Fix the two malformed `statement error` tests so the expected error is
matched inline against the real message
- Add a `statement error` test for `nth < 1`
- Add a test with a pattern column that alternates between two regexes
within a single batch

## Are these changes tested?

Yes, this PR is only tests.

## Are there any user-facing changes?

No

Subject: [PATCH 561/878] Mark null-propagating math functions as strict
 (#23527)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

This PR follows up on #23148, which introduced strictness metadata for
scalar UDF NULL propagation and used it during outer join elimination.
It marks built-in math functions that propagate NULL inputs as strict,
allowing the optimizer to recognize more null-rejecting predicates and
simplify the corresponding outer joins.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Extend the math UDF helper macros to support the `is_strict` property.
- Mark null-propagating math scalar functions as strict.
- Add unit tests covering:
    - supported math functions;
    - unary and binary variants;
    - every combination of NULL arguments;
    - non-NULL inputs.
- Add SQL logic tests showing that strict math predicates enable outer
join elimination for:
    - LEFT, RIGHT, and FULL joins;
    - unary and binary functions;
    - nullable arguments in either position;
    - binary function arguments coming from both sides of a join.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes. Unit tests cover NULL propagation for the affected math functions,
and SLTs verify the resulting outer join simplifications.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Yes. Queries containing null-rejecting predicates over math functions
may now produce more efficient plans by simplifying eligible outer
joins.

There are no public API changes.

Subject: [PATCH 562/878] Fix ordering for UNION ALL over heterogeneous
 constants (#23528)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`add_sort_above` and `add_sort_above_with_distribution` in
physical-optimizer prune every expression that
`EquivalenceProperties::is_expr_constant` reports as constant.
This treats `AcrossPartitions::Heterogeneous` the same as
`AcrossPartitions::Uniform`, which is incorrect.

Check an example:

```sql
SELECT 2 AS sample, c FROM t
UNION ALL
SELECT 1 AS sample, c FROM t
ORDER BY sample, c
```

The union reports sample as a `Heterogeneous` constant and so it gets
pruned, which breaks `ORDER BY`.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Helper that activates pruning only for `AcrossPartitions::Uniform`, use
it at both prune sites (`add_sort_above` and
`add_sort_above_with_distribution`) so `Heterogeneous` constants are
retained.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes, a new unit-test added.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No API changes, just an internal logic bug-fix.

Subject: [PATCH 563/878] fix: handle null date and timestamp format arguments
 (#23641)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23640.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

The formatted `to_date` and `to_timestamp*` functions can produce
internal errors when the input string is NULL or when all format
arguments are NULL.

A NULL value in a format column is also treated as an empty string
instead of being skipped.

`to_unixtime` uses the same timestamp parsing path, so it is affected as
well.


## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Return NULL when the scalar input string is NULL.
- Return NULL when all format arguments are NULL.
- Skip NULL formats in array rows.
- Keep returning a parsing error when all non-NULL formats fail.

## Are these changes tested?

Yes, SLTs were added for `to_date`, `to_timestamp`, and `to_unixtime`.

<!--

Yes, only the bug fix described above. No API changes.

Subject: [PATCH 564/878] perf: optimize `regexp_instr` (40% faster) (#23540)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Optimize existing expression.

## What changes are included in this PR?

Removed per-batch default-array/Vec allocations, memoized the compiled
regex across rows to skip HashMap hashing for literal patterns, and
skipped the O(n) chars() scan on the default start=1 path.

## Are these changes tested?

Existing tests.

Benchmark (criterion):

- regexp_instr_with_start [size=1024, str_len=32]: 40.073% faster (base
41127ns -> cand 24646ns)
- regexp_instr_with_start [size=1024, str_len=128]: 44.498% faster (base
48215ns -> cand 26760ns)
- regexp_instr_no_start [size=1024, str_len=128]: 47.253% faster (base
49244ns -> cand 25974ns)
- regexp_instr_no_start [size=1024, str_len=32]: 42.18% faster (base
40495ns -> cand 23414ns)

Full criterion output:

Subject: [PATCH 565/878] chore: downsize `sql_planner_extended`
 `logical_plan_optimize` sample size to 5 (#23659)

on my M4 Macbook pro, it estimates it would take 50 minutes (!) to run
the benchmark

```sh
datafusion (main)$ cargo bench -p datafusion --bench sql_planner_extended logical_plan
   Compiling datafusion-common v54.0.0 (/Users/jeffrey/Code/datafusion/datafusion/common)
...
   Compiling datafusion v54.0.0 (/Users/jeffrey/Code/datafusion/datafusion/core)
    Finished `bench` profile [optimized] target(s) in 8m 11s
     Running benches/sql_planner_extended.rs (/Users/jeffrey/.cargo_target_cache/release/deps/sql_planner_extended-c026520b80bba716)
Gnuplot not found, using plotters backend
Benchmarking logical_plan_optimize: Warming up for 3.0000 s
Warning: Unable to complete 100 samples in 5.0s. You may wish to increase target time to 3077.4s, or reduce sample count to 10.
Benchmarking logical_plan_optimize: Collecting 100 samples in estimated 3077.4 s (100 iterations)
```

and running it via the bot just times out:
https://github.com/apache/datafusion/pull/23215#issuecomment-4995729774

so might actually be useful to reduce the sample size so it can actually
run and be of use to us

Subject: [PATCH 566/878] Add any_value aggregate function (#23043)

## Which issue does this PR close?

- Closes #22799.

## Rationale for this change

`any_value` is a common aggregate in SQL engines for queries that need
one representative non-null value from each group without imposing an
ordering requirement. DataFusion currently has `first_value`, but that
aggregate is order-sensitive, so exposing `any_value` gives users the
intended arbitrary-value semantics directly.

## What changes are included in this PR?

- Adds an `any_value(expression)` aggregate UDF and registers it with
the default aggregate functions.
- Reuses the existing trivial first-value accumulator with nulls
ignored, so evaluation short-circuits after the first non-null value.
- Marks the aggregate as order-insensitive and preserves the input field
metadata/type in the return field.
- Adds sqllogictest coverage for scalar, grouped, all-null, empty-input,
and string return-type cases.

## Are these changes tested?

Yes. I ran:

```
cargo fmt --all
cargo test -p datafusion-functions-aggregate
cargo test -p datafusion-sqllogictest --test sqllogictests -- aggregate_any_value.slt
cargo clippy --all-targets --all-features -- -D warnings
```

## Are there any user-facing changes?

Yes. This adds a new SQL aggregate function, `any_value`.

I used AI assistance to help inspect the codebase and run validation,
and I reviewed the resulting implementation and tests.

Subject: [PATCH 567/878] feat: Support multiple external table locations
 (#22695)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

Part of #16303.

## Rationale for this change

`CREATE EXTERNAL TABLE` can reference only one location today. This adds
support for listing multiple explicit locations and reading them as one
table.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

  - Adds `LOCATION ('a.parquet', 'b.parquet')` syntax.
- Keeps `LOCATION 'a,b.parquet'` as a single path, so literal commas
still work.
  - Carries multiple locations through the logical plan and proto.
  - Updates listing table creation to scan all listed locations.
- Requires all listed locations to use the same object store and
matching fields.
  - Keeps stream tables limited to exactly one location.
  - Updates docs and upgrade notes.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

Yes. `CREATE EXTERNAL TABLE` now accepts a parenthesized list of
locations.

There is also a public API change: `CreateExternalTable.location` is
replaced by `CreateExternalTable.locations`.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 568/878] perf: don't re-inline CSE'd expensive expressions in
 projection pushdown (#23459)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23425.

Follow-up to #23395 (the volatile correctness fix, now merged),
extending the same projection-pushdown guard to the performance case.

## Rationale for this change

The logical CSE pass extracts a repeated scalar-function call (e.g.
`power(a, 2)`) into a single intermediate projection referenced by
column, so it is evaluated once per row. For file sources that can
absorb computed projections (e.g. Parquet), the physical
projection-pushdown rule then merges that projection into the scan's
`DataSourceExec`, re-inlining the expression at every reference site and
re-evaluating it N times per row — undoing the deduplication.

This is the performance sibling of #23220 (which fixed the *correctness*
case for volatile expressions). It reproduces on file scans
(Parquet/CSV), not in-memory tables.

**EXPLAIN, before** — `power(a, 2)` evaluated 3× per row:

```
DataSourceExec: projection=[power(a,2)+b as x, power(a,2)-b as y, power(a,2)*c as z]
```

**EXPLAIN, after** — `power(a, 2)` evaluated once, kept in a
`ProjectionExec`:

```
ProjectionExec: [__common_expr_1+b as x, __common_expr_1-b as y, __common_expr_1*c as z]
  DataSourceExec: projection=[power(a,2) as __common_expr_1, b, c]
```

## What changes are included in this PR?

- Extends the projection-pushdown guard in
`FileScanConfig::try_swapping_with_projection` so it also declines the
merge when it would duplicate a **non-trivial** expression.
"Non-trivial" is decided by the existing expression-placement signal
(`KeepInPlace`) — the same signal `try_collapse_projection_chain` uses —
covering arithmetic, casts, and most scalar functions. Cheap
leaf-pushable expressions (columns, `get_field`, `input_file_name`)
still merge, so struct-field pushdown is unaffected. It reuses the
volatile guard's multiplicity-aware reference counting, so an expression
is blocked only when referenced more than once.
- Adds the `cse_projection_pushdown` benchmark used to measure the
change.

## Are these changes tested?

Yes:

- Unit tests in `file_scan_config.rs`: a non-trivial expr (arithmetic /
scalar function) referenced ≥2 → blocked, once → allowed; a
leaf-pushable scalar function (`get_field`) → allowed; volatile
referenced ≥2 → blocked, once → allowed.
- `datafusion-sqllogictest` suite passes. One existing plan in
`window.slt` improves: a repeated `c2 >= 2` comparison over a CSV scan
is now computed once instead of being inlined twice into the
`DataSourceExec`.
- Benchmark A/B on `cse_projection_pushdown` (sample-size 50, 5s), with
the `no_repeated_exprs` control confirming no change on unaffected
queries:

| Benchmark | Change |
|---|---|
| `repeated_power` (`power(a,2)` ×3) | −40% |
| `repeated_nested_fn` (`ln(abs(a))` ×3) | −38% |
| `repeated_sqrt` (`sqrt(a)` ×3) | −37% |
| `mixed_repeated_unique` | −35% |
| `repeated_cheap_abs` (`abs(a)` ×3) | within noise |
| `no_repeated_exprs` (control) | no change |

The gain scales with expression cost. For a single-instruction function
like `abs`, caching the value in a `ProjectionExec` versus recomputing
it is a wash (run-to-run noise), since the extra plan node roughly
offsets the recomputation it saves.

Reproduce with:

```
cargo bench -p datafusion --bench cse_projection_pushdown --features parquet
```

## Are there any user-facing changes?

No API changes. Queries that repeat an expensive expression over a file
scan run faster; their physical plans retain a `ProjectionExec` above
the scan (the expression evaluated once) instead of inlining it into the
`DataSourceExec` projection.

Subject: [PATCH 569/878] fix: prevent LEAD/LAG IGNORE NULLS panic without null
 bitmap (#23706)

## Which issue does this PR close?

- Closes #23705.

## Rationale for this change

Arrow arrays containing no null values commonly omit the null bitmap.
The whole-partition evaluation path for `LEAD` and `LAG` with `IGNORE
NULLS` unconditionally unwrapped that optional bitmap, causing a panic
for valid non-null input arrays.

## What changes are included in this PR?

- Fall back to the existing regular shift implementation when the input
has no null bitmap.
- Add a regression test covering both `LEAD` and `LAG` with an array
that explicitly has no null bitmap.

## Are these changes tested?

Yes.



## Are there any user-facing changes?

`LEAD` and `LAG` with `IGNORE NULLS` no longer panic when the input
Arrow array has no null bitmap. There are no public API changes.

Subject: [PATCH 570/878] feat: allow Full joins to reuse range co-partitioning
 in HashJoinExec (#23583)

## Which issue does this PR close?

- Closes #23454.

## Rationale for this change

#23184 let compatible range-partitioned inputs satisfy inner partitioned
hash joins without repartitioning. Full partitioned equi joins still
always went through the conservative hash-repartition path, even when
both inputs were already co-partitioned by range on the join key(s). The
per-partition unmatched-row tracking in `HashJoinExec` is already
partition-local under `PartitionMode::Partitioned` (not shared globally
like in `CollectLeft`), so Full-join semantics generalize cleanly to
range co-partitioning with no additional bookkeeping required.


## What changes are included in this PR?

- Extend `HashJoinExec::input_distribution_requirements()` to opt
`JoinType::Full` in to
`allow_range_satisfaction_for_key_partitioning()`, alongside the
existing `JoinType::Inner` case. The underlying `co_partitioned` /
`compatible_co_partitioning_layout` / `co_partitioning_satisfied` logic
in `distribution_requirements.rs` was already join-type-agnostic, so no
changes were needed there.
- Add planner unit tests in `enforce_distribution.rs` covering both the
compatible-layout case (no repartition inserted) and the
incompatible-split-points case (repartition still inserted) for
`JoinType::Full`.
- Add a `range_partitioned_sparse` sqllogictest fixture table with the
same partition layout as `range_partitioned` but only partially
overlapping keys, and add sqllogictest coverage in
`range_partitioning.slt` for: a compatible Full join avoiding
repartition, an incompatible Full join still repartitioning, and
matched/left-only/right-only unmatched rows produced correctly by a
co-partitioned Full join.

## Are these changes tested?

Yes:
- Two new Rust unit tests in
`datafusion/core/tests/physical_optimizer/enforce_distribution.rs`
assert on the physical plan shape (repartition inserted or not) for
compatible and incompatible range layouts.
- Three new sqllogictest cases in
`datafusion/sqllogictest/test_files/range_partitioning.slt` exercise the
feature end-to-end against real data, including matched rows, left-only
unmatched rows, and right-only unmatched rows for a Full outer join.
- Existing `enforce_distribution` tests, `range_partitioning.slt`, and
proto roundtrip tests all continue to pass.


## Are there any user-facing changes?

Yes: `EXPLAIN` output for `Full` joins over compatible range-partitioned
inputs will no longer show a `RepartitionExec`, and such queries will
avoid the associated hash-shuffle cost at execution time. No public API
changes.

## Rationale for this change

see comment
https://github.com/apache/datafusion/pull/23280#discussion_r3548804883
<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

Adds SQL logic tests to verify that GROUP BY on dictionary-encoded
columns resolves on values rather than raw dictionary key integers. The
tests use UNION ALL between independently-encoded subqueries (mixing
Int32/Int16/Int8 key types and Utf8/LargeUtf8 value types)

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

the test cover

- Correct grouping when the same value maps to different keys in
different batches
- No false merging of distinct values that happen to share the same key
number
- Null handling across batches with mismatched key assignments

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?

Subject: [PATCH 572/878] refactor: pass SubqueryContext explicitly through
 planner traits (#23649)

## Which issue does this PR close?

- Alternative to #22340

## Rationale for this change

When we turn logical plans into physical plans, we have a work around to
get the context for scalar subqueries. Specifically we clone the session
and mutate the `execution_props` where the subquery context currently
sits. This is even called out in the code with comments:

```rust
            // Ideally, the subquery state would live in a dedicated planning
            // context rather than in `ExecutionProps`. It's here because
            // `create_physical_expr` only receives `&ExecutionProps`.
```

The real reason for this is that we want to expose the `QueryPlanner`
via FFI and currently it depends upon downcasts from `Session` to
`SessionState`. That does not work for the FFI crate where we have a
different `Session` implementation. Since we cannot do the downcast, we
cannot use the work around in the current code.

This PR is designed to plumb through the required context properly
rather than rely on manipulating the execution properties.

## What changes are included in this PR?

The major change here is to remove `subquery_indexes` and
`subquery_results` from `ExecutionProps` and put them into their own
struct `SubqueryContext`. Everything else is just refactoring and
plumbing to align around this split of the data.

## Are these changes tested?

- Existing unit tests all pass.
- Added additional unit test to cover user defined expressions.

## Are there any user-facing changes?

Yes, this adds a single parameter into `create_physical_expr`, the
subquery context. The migration guide demonstrates how to add a default
context in for users, if necessary.

+
+### Scalar-subquery state moved to an explicit `PhysicalPlanningContext`
+
+The `subquery_indexes` and `subquery_results` public fields on
+`datafusion_expr::execution_props::ExecutionProps` have been removed. They were
+added in `54.0.0` as the channel through which the physical planner passed
+uncorrelated scalar-subquery state to functions that create physical
+`Arc<dyn PhysicalExpr>` values from logical `Expr` values.
+
+That state is now carried by a dedicated
+`datafusion_expr::physical_planning_context::PhysicalPlanningContext` passed explicitly
+through functions and planner traits. Unlike `ExecutionProps`, which applies
+throughout the planning of an entire query, this context is scoped to the
+logical plan subtree currently being converted. This removes the need for the
+physical planner to clone and mutate a `SessionState`, is a prerequisite for
+letting the planner take `&dyn Session`, and lets `ExtensionPlanner`
+implementations create physical
+expressions containing scalar subqueries against the same subquery state as the
+rest of the plan.
+
+The following functions take a new trailing
+`planning_ctx: &PhysicalPlanningContext` parameter:
+
+- `datafusion_physical_expr::create_physical_expr` / `create_physical_exprs`
+- `datafusion_physical_expr::create_physical_sort_expr` /
+  `create_physical_sort_exprs` / `create_physical_partitioning`
+- `datafusion::physical_planner::create_window_expr` /
+  `create_window_expr_with_name`
+- `datafusion_physical_expr::aggregate::LoweredAggregateBuilder::new`
+
+The planner traits changed accordingly:
+
+- `PhysicalPlanner::create_physical_expr` takes
+  `planning_ctx: &PhysicalPlanningContext`
+- `ExtensionPlanner::plan_extension` and `plan_table_scan` receive
+  `planning_ctx: &PhysicalPlanningContext` and should forward it to
+  `PhysicalPlanner::create_physical_expr` when creating physical expressions
+
+Convenience methods such as `SessionContext::create_physical_expr` and
+`SessionState::create_physical_expr` are unchanged.
+
+**Who is affected:**
+
+- Code calling the functions above: pass
+  `&PhysicalPlanningContext::default()` unless you are creating physical
+  expressions as part of a physical plan that contains uncorrelated scalar
+  subqueries.
+- Custom `PhysicalPlanner` or `ExtensionPlanner` implementations: add the new
+  parameter and forward it.
+- Code that read or wrote `execution_props.subquery_indexes` /
+  `execution_props.subquery_results`: build a `PhysicalPlanningContext` instead.
+
+**Migration guide:**
+
+When creating a physical expression outside of physical planning, pass an empty
+context:
+
+```rust,ignore
+use datafusion_expr::physical_planning_context::PhysicalPlanningContext;
+use datafusion_physical_expr::create_physical_expr;
+
+// Before
+let phys = create_physical_expr(&expr, &schema, &props)?;
+
+// After
+let phys = create_physical_expr(
+    &expr,
+    &schema,
+    &props,
+    &PhysicalPlanningContext::default(),
+)?;
+```
+
+For `ExtensionPlanner` implementations, accept and forward the context:
+
+```rust,ignore
+async fn plan_extension(
+    &self,
+    planner: &dyn PhysicalPlanner,
+    node: &dyn UserDefinedLogicalNode,
+    logical_inputs: &[&LogicalPlan],
+    physical_inputs: &[Arc<dyn ExecutionPlan>],
+    session_state: &SessionState,
+    planning_ctx: &PhysicalPlanningContext, // new parameter
+) -> Result<Option<Arc<dyn ExecutionPlan>>> {
+    for expr in node.expressions() {
+        // Forward the context so scalar subqueries in this node's
+        // expressions resolve against the plan's subquery state
+        planner.create_physical_expr(&expr, node.schema(), session_state, planning_ctx)?;
+    }
+    // ...
+}
+```

Subject: [PATCH 573/878] bench: parquet scan with a table schema narrower than
 a nested column (#23397)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Related to https://github.com/apache/datafusion-comet/issues/4859.
Second of a 3-PR stack: #23396 (refactor), this benchmark, and the
feature PR (nested schema pruning for the parquet reader).

## Rationale for this change

When a table's declared schema is narrower than a parquet file's nested
column (logical `events: LIST<STRUCT<x, y>>` over a physical
`LIST<STRUCT<x, y, +8 pads>>`), the reader currently fetches and decodes
**every** leaf of the column and discards the extra subfields in memory
via the adapter-inserted cast. This is how engines like Spark (via
Comet) communicate nested projection pruning to the scan — as a clipped
read schema — and it is where Comet measured reading 1.35 TB where Spark
read 30.9 GB for the same pruned `ReadSchema`.

This PR adds a benchmark that documents the current behavior as a
checked-in baseline, independent of any fix:

```
list_struct_narrow_schema:      bytes_scanned=25.19 MB   3.45 ms
list_struct_full_schema:        bytes_scanned=25.19 MB   3.36 ms   <- narrow == full today
list_struct_physically_narrow:  bytes_scanned= 3.32 KB    164 µs   <- the floor
```

## What changes are included in this PR?

A criterion benchmark,
`datafusion/core/benches/parquet_nested_schema_pruning.rs`, that
registers the same wide `list<struct>` (and top-level struct) parquet
file with both its full schema and a narrower declared schema, plus a
physically-narrow file as the floor, and prints the scans'
`bytes_scanned` at setup so the IO pattern is visible alongside wall
time.

## Are these changes tested?

It is a benchmark; it compiles under `cargo bench --no-run` and runs
green.

## Are there any user-facing changes?

No.

+//! Benchmarks for schema-driven nested projection pruning in Parquet.
+//!
+//! A table's declared (logical) schema can be *narrower* than the physical
+//! parquet type of a nested column — e.g. the table declares
+//! `events: LIST<STRUCT<x, y>>` while the file contains
+//! `events: LIST<STRUCT<x, y, pad_0, ..., pad_7>>`. Engines like Spark
+//! communicate nested projection pruning to the scan exactly this way
+//! (a clipped read schema), so the reader should fetch and decode only the
+//! leaves the declared schema names.
+//!
+//! Each dataset shape is measured three ways:
+//!
+//! 1. **narrow_schema**: wide file, narrow declared table schema — the
+//!    interesting case; ideally close to (3)
+//! 2. **full_schema**: wide file, full table schema — the cost of reading
+//!    everything
+//! 3. **physically_narrow**: a file that only contains the narrow columns —
+//!    the floor
+//!
+//! At setup the benchmark reads the parquet scan's `bytes_scanned` metric for
+//! (1), (2) and (3) so the IO pattern is visible in addition to wall time, and
+//! asserts the current baseline: today a narrow declared schema scans the same
+//! bytes as the full schema. When nested projection pruning lands, that
+//! assertion is expected to fail, which is the signal to flip it to
+//! `narrow < full` (see [`assert_scan_baseline`]).

Subject: [PATCH 574/878] fix: Preserve metadata when a cross-join is swapped
 (#23605)

## Which issue does this PR close?

- Relates to #23461 but resolves it only for cross-joins. The same
problem exisists for Hash/NL joins. There will be follow-ups.

## Rationale for this change

When a `cross-join` is swapped, the metadata is rebuilt based on the
inverted inputs. This can cause a change of metadata when the metadata
has conflicting values e.g.:

```rust
// left: 1000 rows, schema metadata {"key": "left"}
// right: 2 rows, schema metadata {"key": "right"}
// Cross join will swap the sides
ctx.sql("select * from left cross join right").await?.collect().await?;
// -> Internal error: ... 'join_selection' failed. Schema mismatch.
// Metadata should be {"key" : "right" } but changed to {"key" : "left" }
// because of the swap of sides and the rebuilt of the metadata starting from the other direction.
```

The cross-join should preserve the original metdata when it's swapped.


## What changes are included in this PR?

- This pr avoids rebuilding the metadata based on the swapped inputs and
uses the original metadata instead
- Test

## Are these changes tested?

Yes

## Are there any user-facing changes?

No

Subject: [PATCH 575/878] Cap SortPreservingMerge statistics by fetch (#23359)

## Which issue does this PR close?

- Closes none.

## Rationale for this change

`SortPreservingMergeExec` supports `fetch`, but its statistics currently
pass through child statistics unchanged. This can make cost-based
optimizers overestimate top-k merge outputs. For example, a
`SortPreservingMergeExec(fetch=1)` side can still look as large as its
input to `JoinSelection`, causing hash join build/probe choices to miss
the small top-k side.

Other fetch-aware operators such as `SortExec`,
`CoalescePartitionsExec`, and limit execs already cap their statistics
by fetch. This PR aligns `SortPreservingMergeExec` with that behavior.

## What changes are included in this PR?

- Cap `SortPreservingMergeExec` statistics with
`Statistics::with_fetch(self.fetch, 0, 1)`.
- Preserve no-op statistics for `fetch = None` and `skip = 0`.
- Avoid scaling byte-size estimates by `0.0` when input row count is
unknown; use absent byte-size stats instead.
- Add regression tests for SPM fetch statistics and for `JoinSelection`
swapping an SPM(fetch=1) side to the hash join build side.

## Are these changes tested?

Yes.

- `cargo test -p datafusion-common test_with_fetch`
- `cargo test -p datafusion-physical-plan sort_preserving_merge`
- `cargo test -p datafusion join_selection --test core_integration`
- `cargo check -p datafusion --test core_integration`
- `cargo fmt --all -- --check`
- `cargo clippy --all-targets --all-features -- -D warnings`

## Are there any user-facing changes?

No user-facing API changes. This improves optimizer statistics for
fetch-limited sort-preserving merge plans.

Subject: [PATCH 576/878] fix: coerce SIMILAR TO operands to a common string
 type (#23704)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22886

## Rationale for this change

`SIMILAR TO` panics with `failed to downcast array` whenever its
operands end up as arrays of different physical types:

```sql
SELECT 'a' SIMILAR TO NULL;  -- panics during planning (constant folding)

CREATE TABLE t AS SELECT * FROM (VALUES ('user auth failed')) v(s);
CREATE TABLE p AS SELECT * FROM (VALUES ('(auth|login)')) v(pat);
SELECT arrow_cast(t.s, 'Utf8View') SIMILAR TO p.pat FROM t CROSS JOIN p;  -- panics at runtime
```

Root cause: `SIMILAR TO` is planned as a regex binary operator
(`RegexMatch` et al.), whose kernel downcasts both arrays to the left
operand's array type. But unlike `LIKE` and the regex operators (`~`,
`~*`, ...), the `TypeCoercion` analyzer never coerced `Expr::SimilarTo`
operands — it was listed in the "nothing to coerce" arm of
`TypeCoercionRewriter` — so any type mismatch reached the kernel
un-normalized and hit a blind `.expect()`. Literal patterns take a
scalar fast path, which is why the common `col SIMILAR TO 'pattern'`
form never showed this.

## What changes are included in this PR?

Two commits:

1. **Coerce `SIMILAR TO` operands in the analyzer**
(`datafusion/optimizer/src/analyzer/type_coercion.rs`)
- Extract the existing `LIKE`-operand coercion into
`coerce_like_operands` (behavior for `LIKE`/`ILIKE` is unchanged,
including the `Dictionary(_, Utf8)` special case and error texts).
- Apply `regex_coercion` to `Expr::SimilarTo` — the same coercion the
physical regex operators it is planned into use
(`expr-common/src/type_coercion/binary.rs:218`). A `NULL` pattern is
coerced to a typed NULL and evaluates to NULL (matching `expr ~ NULL`),
and mixed string types are unified before planning.
- Regression coverage in `type_coercion.slt` (both reproducers, NULL
variants, and the planning-error path) plus analyzer unit tests.

2. **Defense in depth in the regex kernels**
(`datafusion/physical-expr/src/expressions/binary/kernels.rs`)
- Replace `.expect("failed to downcast array")` in
`regexp_is_match_flag!` / `regexp_is_match_flag_scalar!` with
`exec_err!`, so any expression path that bypasses the analyzer (e.g. a
hand-built plan going straight to physical planning) returns an error
instead of panicking. Includes a unit test constructing a mismatched
`RegexMatch` directly.

## Are these changes tested?

Yes:
- sqllogictest: 7 new cases in `type_coercion.slt` (issue reproducers,
`NULL`/`NOT SIMILAR TO NULL`, `LargeUtf8` × `Utf8`, incompatible-type
planning error).
- Unit tests: analyzer coercion plans (NULL pattern, cross string types,
error case) and a kernel-level test proving mismatched arrays now error
instead of panic.
- Verified `./dev/rust_lint.sh`, `cargo test -p datafusion-optimizer
--lib`, `cargo test -p datafusion-physical-expr --lib`, and the relevant
sqllogictest files (`type_coercion`, `strings`, `scalar`, `regexp`,
`string`) — all green.

## Are there any user-facing changes?

Only the bug fix: queries that previously panicked now either evaluate
correctly (`Utf8View` × `Utf8` etc.) or return NULL / a planning error.
`LIKE`/`ILIKE` behavior is unchanged.

Subject: [PATCH 577/878] docs: update Polygon.io reference to Massive.com
 (#23734)

## Which issue does this PR close?

N/A.

## Rationale for this change

Polygon.io has rebranded as Massive.com, so the user guide should use
the current company name and website.

## What changes are included in this PR?

Updates the project listing from Polygon.io to Massive.com and replaces
the old URL with https://massive.com/.

## Are these changes tested?

Yes. The following required checks passed:

- `cargo fmt --all`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `./ci/scripts/doc_prettier_check.sh --write --allow-dirty`

## Are there any user-facing changes?

Yes. The user guide now displays the current Massive.com branding and
website.

Subject: [PATCH 578/878] feat(proto): thread expr encode/decode context into
 try_encode_expr / try_decode_expr (#23733)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Closes #22920.

Alternative to #22922 — same goal, but plumbs the per-expr encode/decode
**context** (from the #22418 hook machinery) instead of the raw
`PhysicalProtoConverterExtension`.

## Rationale for this change

#21807 introduced the `DynamicFilterPhysicalExpr` dedup pipeline so
identical references on the wire reconstruct to one shared `Arc<Inner>`
via `expr_id` cache keys, and #22011 hooked it through the `SortExec` /
`AggregateExec` / `HashJoinExec` plan codecs.

The remaining gap is the **expression-level** extension path. In
`serialize_physical_expr_with_converter` /
`parse_physical_expr_with_converter`, the codec's `try_encode_expr` /
`try_decode_expr` is reached only as a fallback after the built-in
`try_to_proto` path and the `ScalarFunctionExpr` downcast — i.e. only
for downstream-defined **custom `PhysicalExpr`** types. When such a
codec serializes nested `PhysicalExprNode` fields *inside its own blob*,
the only helper available today is the free `serialize_physical_expr` /
`parse_physical_expr`, hardwired to `DefaultPhysicalProtoConverter`. So
those nested exprs get `expr_id: None` on the wire and reconstruct as
**distinct** `Inner` allocations — heap-max updates from a `SortExec`
never reach the wrapped reference.

## What changes are included in this PR?

The built-in expressions migrated under #22418 already receive a
`PhysicalExprEncodeCtx` / `PhysicalExprDecodeCtx` in their
`try_to_proto` / `try_from_proto` hooks. Those context objects bundle
the dedup-aware converter **plus** the active schema and task context,
and hide `PhysicalProtoConverterExtension` / `PhysicalExtensionCodec`
from the expression author entirely.

This PR hands the **same context** to the expr-level codec methods:

```rust
fn try_decode_expr(
    &self,
    buf: &[u8],
    inputs: &[Arc<dyn PhysicalExpr>],
    ctx: &PhysicalExprDecodeCtx<'_>,   // new
) -> Result<Arc<dyn PhysicalExpr>>;

fn try_encode_expr(
    &self,
    node: &Arc<dyn PhysicalExpr>,
    buf: &mut Vec<u8>,
    ctx: &PhysicalExprEncodeCtx<'_>,   // new
) -> Result<()>;
```

A codec that embeds nested `PhysicalExprNode`s now decodes them with
`ctx.decode(..)` and encodes them with `ctx.encode_child(..)`, which:

- route through any active `DeduplicatingProtoConverter` /
`DeduplicatingDeserializer`, so shared inner expressions cache-hit on
`expr_id`; **and**
- carry the real schema and task context, so nested UDF / column
references resolve against the actual registry.

### Why the context, not the raw converter (cf. #22922)

Threading the bare `PhysicalProtoConverterExtension` still leaves the
codec without the schema/registry, forcing it to fabricate a
`SessionContext::new()` and hard-code a schema to call
`proto_to_physical_expr` — an empty-registry footgun for any nested expr
that references a UDF or column. Passing the existing
`Physical{Encode,Decode}Ctx` avoids that, keeps the extension
escape-hatch consistent with the per-expr proto hooks, and adds no third
converter parameter to the codec API (the concern raised on #22922).

## Are these changes tested?

Yes — `extension_codec_expr_participates_in_deduplication` builds a
`BinaryExpr` whose left operand is a bare `DynamicFilterPhysicalExpr`
and whose right operand is a custom `WrapperExpr` whose codec embeds the
same dynamic filter inside its serialized blob (via `ctx.encode_child`).
After a `DeduplicatingProtoConverter` roundtrip, an `update()` on the
bare-side decoded filter is observed via `current()` on the wrapped-side
filter, proving both refs back the same `Inner`. The codec needs no
fabricated `SessionContext` — it decodes the nested expr through
`ctx.decode`.

## Are there any user-facing changes?

Yes — a **breaking change** for downstream codecs that override
`try_encode_expr` / `try_decode_expr`: they must add the new `ctx`
parameter (name it `_ctx` if the custom expr carries no nested
`PhysicalExprNode`s). Codecs that only override the plan-level
`try_encode` / `try_decode` are unaffected. Wire format is unchanged.

Subject: [PATCH 579/878] refactor(proto): migrate FilterExec serde (#23708)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23499.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

The centralized protobuf dispatcher couples each execution plan to
datafusion-proto. Adding plan serialization therefore requires changes
outside the plan implementation.

Move FilterExec encoding and decoding behind its ExecutionPlan hooks.
Preserve the existing wire format and retain the old helper methods as
deprecated compatibility APIs.


## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 580/878] refactor(proto): migrate single-child plans (#23710)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23500.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Physical plan serialization currently relies on centralized type
dispatch in `datafusion-proto`. This separates serialization from the
plans that own the relevant state and requires every built-in plan to
be handled specially.

Moving serialization into each plan keeps that logic with its owner and
allows the central dispatch chain to be removed incrementally.

`CoalesceBatchesExec` is deprecated but remains a supported public type.
Migrating its existing serialization keeps the dispatch model
consistent without extending its lifetime or changing its behavior.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add per-plan protobuf encoding and decoding for:
  - `CoalesceBatchesExec`
  - `CoalescePartitionsExec`
  - `CooperativeExec`
  - `BufferExec`
- Route decoding through each plan's `try_from_proto` implementation.
- Remove the corresponding centralized encoding branches.
- Retain the old public conversion helpers as deprecated compatibility
  APIs.
- Preserve the existing protobuf wire representation.
- Add roundtrip coverage for `CooperativeExec` and `BufferExec`.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
There are no runtime behavior or protobuf wire-format changes.

The old `PhysicalPlanNodeExt` conversion helpers remain available but
are deprecated in favor of the per-plan serialization hooks.

Subject: [PATCH 581/878] refactor(proto): migrate sort merge join serde
 (#23712)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23508 .

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`SortMergeJoinExec` serialization currently depends on centralized
encoding and decoding logic in `datafusion-proto`. This keeps protobuf
ownership separate from the execution plan and contributes to the
central type-dispatch chain tracked by #23494.

Moving serialization into `SortMergeJoinExec` keeps the implementation
with the plan that owns the relevant state and aligns it with the new
per-plan serialization model.


## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add `ExecutionPlan::try_to_proto` for `SortMergeJoinExec`.
- Add `SortMergeJoinExec::try_from_proto`.
- Preserve serialization of:
  - Both child plans.
  - Join-key expressions.
  - Join type and null-equality behavior.
  - Optional join filters and column origins.
  - Per-key sort options.
- Convert `JoinType`, `JoinSide`, and `NullEquality` through exhaustive
  by-name matches.
- Route decoding through the plan-local implementation and remove the
  centralized encoding downcast.
- Retain the old public conversion helpers as deprecated compatibility
  APIs.
- Preserve the existing protobuf wire representation.
- Expand roundtrip coverage for every join type, both null-equality
  modes, filters, column origins, and non-default sort options.

## Are these changes tested?
Yes
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
There are no runtime behavior or protobuf wire-format changes.

The old `PhysicalPlanNodeExt` conversion helpers remain available but
are deprecated in favor of the plan-local serialization hooks.

#23184 let compatible range-partitioned inputs satisfy **inner**
partitioned hash joins without repartitioning. Right-side partitioned
equi joins have the same locality guarantee: `Right`, `RightSemi`,
`RightAnti` and `RightMark` all anchor every output row on the probe
(right) partition (`on_lr_is_preserved` is probe-side for all four), so
when both inputs are co-partitioned by the join keys, execution stays
partition-local and the hash repartition is unnecessary.

This removes unnecessary `RepartitionExec`s for already-co-located
inputs, extending the inner-join behavior from #23184 to the right-side
variants. No micro-benchmark included, consistent with #23184;
correctness is demonstrated by matched/unmatched execution results
below.

## What changes are included in this PR?

The only production change is widening the existing inner-only gate in
`HashJoinExec::input_distribution_requirements` from `join_type ==
JoinType::Inner` to `matches!(join_type, Inner | Right | RightSemi |
RightAnti | RightMark)` (under `PartitionMode::Partitioned`). The
`co_partitioned` / range-satisfaction machinery from #23184 is unchanged
— the sanity checker and enforce_distribution consume range satisfaction
join-type-agnostically.

One behavior note for #23376: range co-partitioned right joins now stay
`Range`/`Range`, so partitioned dynamic filters are disabled for them
(`has_partitioned_dynamic_filter_routing` returns false), the same safe
delta #23184 introduced for inner joins. These variants are
probe-not-preserved for pruning, so dynamic filters were not eligible to
prune their probe rows regardless.

## Are these changes tested?

Yes.

- Optimizer (`enforce_distribution.rs`): 4 reuse tests (one per join
type) proving compatible range/range inputs keep `Range` partitioning
with no `RepartitionExec`; 4 incompatibility tests proving that
mismatched split points, sort options, partition counts, or join-key
expressions still insert a hash repartition; sanity-check pairs
mirroring #23184.
- Execution (`range_partitioning.slt`): `EXPLAIN` plan pins plus
matched/unmatched result checks for `Right` (incl. `NULL` left values),
`RightSemi`, `RightAnti`, and an incompatible-layout `Right` join
(repartitions, correct results).
- The new reuse tests fail on `main` without the gate change (verified
by reverting the production diff: exactly the 4 reuse tests fail,
everything else passes).
- `RightMark` testing note: `RightMark` is not reachable from SQL in
sqllogictest (`IN`-subquery decorrelation emits `LeftMark`; physical
`RightMark` only appears via a statistics-based swap), so its
co-partitioning behavior is pinned at the optimizer/plan level, and mark
null-marker semantics (matched/unmatched/`NULL` build keys) are pinned
via the `LeftMark` path in the slt.

## Are there any user-facing changes?

No API changes. Plans over compatible range-partitioned inputs avoid a
hash repartition for right-side equi hash joins.

Subject: [PATCH 584/878] feat: complete range repartition physical planning
 (#23617)

## Which issue does this PR close?

- Closes #23230

## Rationale for this change

After #23231 was merged in for supporting physical execution of the
range repartitioning scheme, we still had a few methods on physical
planning unimplemented, specifically `try_swapping_with_projection`,
`try_pushdown_sort`, `repartitioned` - this PR finishes the
implementation of those methods

## What changes are included in this PR?

- `try_swapping_with_projection`: similar to the `Hash` scheme, for
`Range` we call `update_expr` for each of the range key expressions to
attempt rewriting based on the projection expressions
- `try_pushdown_sort`: same as other variants, we delegate to the child
and wrap with a new `RepartitionExec`
- `repartitioned`: unable to support for Range, left comment in codebase
with explanation

## Are these changes tested?

Yes

## Are there any user-facing changes?

No

Subject: [PATCH 586/878] feat(physical-plan): Allow co-partitioned
 Partitioning::Range inputs for left-side hash joins (#23487)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23452

## Rationale for this change

Allows compatible `Partitioning::Range` inputs to satisfy partitioned
hash join distribution requirements for left-side joins, avoiding
unnecessary hash repartitioning.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

- Enables range co-partitioning satisfaction for `Left`, `LeftSemi`,
`LeftAnti`, and `LeftMark` hash joins.
- Adds optimizer and sqllogictest coverage for compatible and
incompatible range layouts.
- Covers matched/unmatched rows and LeftMark null-related marker
behavior.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes. Added/updated physical optimizer tests and
`range_partitioning.slt`.

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Writing larger row groups requires more memory to write, but can get better compression and be faster to read. When `max_row_group_bytes` is also set, the writer flushes a row group when either limit is reached, whichever comes first.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  |
 | datafusion.execution.parquet.max_row_group_bytes                        | NULL                      | (writing) Target maximum size of each row group in bytes. When set, the writer flushes whenever either this limit or `max_row_group_size` is reached, whichever comes first. Useful for bounding writer memory on wide schemas where a row-count limit can map to very different byte sizes. Matches the behavior of `parquet.block.size` in parquet-mr. If `None` (the default), only the row-count limit applies. Currently only honored when `allow_single_file_parallelism` is `false`; by default the parallel file writer ignores this limit.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

Subject: [PATCH 588/878] fix: Capture global ORDER BY requirement under
 ScalarSubqueryExec root (#23677)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

After the DataFusion 53 → 54 upgrade, some queries with a
`ScalarSubquery` stopped respecting the global `ORDER BY` and returned
unordered results.

## Rationale for this change

In add mode, `OutputRequirements` walks the plan via
`require_top_ordering_helper` to capture the global `ORDER BY` as an
`OutputRequirementExec`. The helper bails on any node with
`children.len() != 1`. `ScalarSubqueryExec` has multiple children (child
0 = order-transparent main input, the rest = uncorrelated subquery
plans),
so when it is the root the rule stops immediately and stamps an empty
`OutputRequirementExec(order_by=[], dist_by=Unspecified)` at the top —
losing the ordering requirement.

`ScalarSubqueryExec` is order-transparent on child 0
(`maintains_input_order()[0]== true`, no required input ordering), so
the search should descend through it like any other single-child
order-preserving operator.

## What changes are included in this PR?

`require_top_ordering_helper` now special-cases `ScalarSubqueryExec`: it
descends through child 0 to find and wrap the top `SortExec` /
`SortPreservingMergeExec`, reattaching the subquery children unchanged.

## Are these changes tested?

Yes — two tests in
`datafusion/core/tests/physical_optimizer/output_requirements.rs`:

1. **Rule level**
(`require_top_ordering_descends_through_scalar_subquery`): asserts the
`OutputRequirementExec` carrying the ordering is placed *below* the
`ScalarSubqueryExec`; without the fix it lands empty at the root.

2. **End to end**
(`scalar_subquery_root_preserves_global_ordering_end_to_end`): runs the
full default optimizer pipeline over a `ScalarSubqueryExec` root whose
ordering comes from a `SortPreservingMergeExec` over a two-partition
ordered source, then executes the plan and checks the rows. Verified by
toggling the fix:

   | | executed output |
   |---|---|
| **without fix** | `1, 3, 5, 7, 2, 4, 6, 8` — merge dropped, rows
partition-interleaved |
   | **with fix** | `1, 2, 3, 4, 5, 6, 7, 8` — globally ordered |

Existing `subquery.slt` / TPC-H snapshots are unchanged. I was unable to
construct a SQL query that triggers the bug - over built-in sources the
global `ORDER BY` is always preserved regardless of the missing
requirement. It only surfaces when a custom physical planner supplies a
plan shaped like the end-to-end test: a `SortPreservingMergeExec` over
already-sorted partitions, with no `SortExec` above it.

## Are there any user-facing changes?

No.

<h2>v5.2.6</h2>
<h3>Patch Changes</h3>
<ul>
<li>
<p>fix: allow <code>undefined</code> as the <code>Server</code>
constructor <code>options</code> argument again (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5695">#5695</a>)</p>
<p>Restores accepting <code>undefined</code> (defaulting it to
<code>{}</code>) for the <code>options</code>
argument, so passing a webpack config's optional <code>devServer</code>
field type-checks and works as before.</p>
</li>
<li>
<p>Protect the built-in state-changing routes
(<code>/webpack-dev-server/invalidate</code> and
<code>/webpack-dev-server/open-editor</code>) against cross-site request
forgery. Requests are now checked with <code>Sec-Fetch-Site</code>
(falling back to an <code>Origin</code>/<code>Host</code> comparison
when it is absent), so a cross-site page can no longer trigger a rebuild
or open a file in the editor. Same-origin requests, user-initiated
navigations, and non-browser clients (e.g. curl) are unaffected. (by <a

Subject: [PATCH 594/878] docs: add Supermetal to known users (#23790)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

About Supermetal:
> Supermetal is a change data capture (CDC) platform that synchronizes
data between databases, data warehouses, and lakehouses while preserving
transactional consistency. It handles low latency streaming and large
scale batch movement with exceptional compute efficiency, replicating
terabytes on hardware as small as a 2 vCPU, 8GB instance.

> It ships as a single binary with no external dependencies and runs
anywhere, on premise, hybrid, or multi cloud.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

Adds [Supermetal](https://supermetal.io/) (https://supermetal.io/), a
change data capture platform, to the list of known DataFusion users.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 595/878] feat: Range Partitioning FFI (#23520)

## Which issue does this PR close?

- Closes #22394

## Rationale for this change

Exposing range partition metadata via the FFI for external consumers.

## What changes are included in this PR?

- Added FFI mirror struct for `RangePartitioning` and added new enum
variant for range in `FFI_Partitioning`
- For native -> FFI, added match arm for the new variant, same with FFI
-> native but changed the approach of `From` -> `TryFrom` to utilize the
validation for `RangePartitioning` and modified `plan_properties` to
match
- Added tests


## Are these changes tested?

Yes

## Are there any user-facing changes?
Yes, exposing Range partitioning over FFI. This exposes a new `Range`
variant in the `FFI_Partitioning` enum, which may cause consumers of
this enum to add another arm to match statements to handle the new enum.
New `FFI_RangePartitioning` struct for the `Range` variant.

Subject: [PATCH 596/878] fix: avoid overflow in join cardinality estimation
 (#23788)

## Which issue does this PR close?

- Closes #23787.

## Rationale for this change

Join cardinality estimation multiplies two `usize` row counts before
applying the join-key NDV divisor. A large Cartesian-product
intermediate can therefore overflow and panic even when the normalized
cardinality is representable. Saturating the product before division
would avoid the panic but produce an inaccurate estimate.

## What changes are included in this PR?

- Compute the Cartesian-product intermediate with `u128` before applying
the NDV divisor.
- Preserve exact estimates when the normalized result fits in `usize`.
- Cap an unrepresentable final result at `usize::MAX` and mark it
inexact, consistent with existing statistics arithmetic.
- Add regression coverage for exact and inexact statistics and for
final-result overflow.

## Are these changes tested?

Yes.
## Are there any user-facing changes?

Queries with very large join statistics no longer panic during
cardinality estimation. There are no public API changes.

Updates `regex` from 1.13.0 to 1.13.1
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/rust-lang/regex/blob/master/CHANGELOG.md">regex's
changelog</a>.</em></p>
<blockquote>
<h1>1.13.1 (2026-07-15)</h1>
<p>This is a release that fixes a bug where incorrect regex match
offsets could be
reported. Note that this doesn't impact whether a match occurs or not,
just
where it occurs. The match offsets are still valid for slicing, they
just may
not refer to the correct leftmost-first match. See
<a
href="https://redirect.github.com/rust-lang/regex/pull/1364">#1364</a>
for (many) more details.</p>
<p>Bug fixes:</p>
<ul>
<li><a

Fixes previously unsound reverse suffix and inner optimizations.</li>

Updates `libc` from 0.2.186 to 0.2.188
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/rust-lang/libc/releases">libc's
releases</a>.</em></p>
<blockquote>
<h2>0.2.188</h2>
<h3>Changed</h3>
<ul>
<li>Restore <code>Send</code> and <code>Sync</code> for <code>DIR</code>
(<a
href="https://github.com/rust-lang/libc/commit/35b062263401733cd89065c6a553640f2ba51ff1">35b062263401</a>)</li>
</ul>
<p>These were removed in 0.2.187 because <code>libc</code> does not
actually make <code>Send</code> and <code>Sync</code>
guarantees about <code>DIR</code> (or other extern types), but this
caused some crates to break.
The traits are added back for now to allow time to migrate, but will be
removed again
in the future; please make sure your crates are not relying on
<code>libc::DIR: Send</code> or
<code>libc::DIR: Sync</code>.</p>
<h2>0.2.187</h2>
<p>This release contains a number of improvements related to 64-bit
<code>time_t</code> configuration.
Of note the existing <code>RUST_LIBC_UNSTABLE_*</code> environment
variables have been replaced
with configuration options. The new way to use these is:</p>
<pre lang="sh"><code>RUSTFLAGS='--cfg=libc_unstable_musl_v1_2_3' cargo
...
RUSTFLAGS='--cfg=libc_unstable_gnu_time_bits=&quot;64&quot;' cargo ...
</code></pre>
<p>Being able to set this via <code>RUSTFLAGS</code> makes it easier to
only apply configuration to
specific targets (and notably, not the host if build scripts are
used).</p>
<p>There are two other notable changes:</p>
<ul>
<li>
<p>The 32-bit <code>windows-gnu</code> targets now respect
<code>libc_unstable_gnu_time_bits</code></p>
</li>
<li>
<p>uClibc now supports a similar configuration option:</p>
<pre lang="sh"><code>RUSTFLAGS='--cfg=libc_unstable_uclibc_time64'
</code></pre>
</li>
</ul>
<p>As a reminder, these options are under active development and may
change in the future
(hence the &quot;unstable&quot; in the name). It likely that we will
harmonize everything under a
single configuration option before considering them stable.</p>
<h3>Support</h3>
<ul>
<li>Add support for <code>aarch64-unknown-linux-pauthtest</code> (<a
href="https://redirect.github.com/rust-lang/libc/pull/5065">#5065</a>)</li>
<li>Add support for new QNX targets (<a
href="https://redirect.github.com/rust-lang/libc/pull/5241">#5241</a>)</li>
<li>Better document breaking change policy and recommended usage (<a
href="https://redirect.github.com/rust-lang/libc/pull/5179">#5179</a>)</li>
</ul>
<h3>Added</h3>
<ul>
<li>Android: Add <code>POSIX_SPAWN_*</code> constants (<a
href="https://redirect.github.com/rust-lang/libc/pull/5104">#5104</a>)</li>

Updates `stabby` from 72.1.8 to 72.1.16
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/ZettaScaleLabs/stabby/blob/main/CHANGELOG.md">stabby's
changelog</a>.</em></p>
<blockquote>
<h1>72.1.16 (api=3.0.4, abi=2.0.0)</h1>
<ul>
<li>Fix clippy lints for 1.97, and a few typos.</li>
<li><code>Vec::try_drain</code>'s index validation was reversed, making
it not only buggy, but unsound:
<ul>
<li>it would always reject ranges that were in bound, and out-of-bounds
ranges could be accepted, risking multiple UBs:
<ul>
<li><code>Vec::set_len</code> could extend the vec into uninitialized
memory,</li>
<li>the returned <code>Drain</code> could iterate over uninitialized
memory as well.</li>
</ul>
</li>
<li>Hopefully, no users were impacted: <code>Vec::drain</code> (which I
expect most users would pick unless they wanted to guarantee no panics
could ever occur) was always valid, and I expect most users who tried
<code>try_drain</code> found it to not work (since it rejected all valid
input).</li>
<li>Thanks to <a
href="https://github.com/eslerm"><code>@​eslerm</code></a>, who raised
the issue privately to avoid broadcasting it before a fix would be made
available.</li>
</ul>
</li>
<li>Improved error message when a stabbied trait declaration attempts to
use <code>Self</code> in signature, <a
href="https://redirect.github.com/ZettaScaleLabs/stabby/issues/101">#101</a>
shows that the previous error message was absolutely useless to
users.</li>

Subject: [PATCH 598/878] perf: optimize left_right in datafusion-functions
 (#23762)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Optimize existing expression.

## What changes are included in this PR?

Added an ASCII fast path to left_right_byte_length so left/right compute
the n-th codepoint byte offset via O(1) arithmetic instead of a per-row
char_indices() UTF-8 scan.

## Are these changes tested?

Existing tests.

Benchmark (criterion):

- string_view short_result: 4.848% faster (base 56784ns -> cand 54031ns)
- string long_result: 38.098% faster (base 141926ns -> cand 87855ns)
- string_view long_result: 44.817% faster (base 94346ns -> cand 52063ns)
- string short_result: 13.184% faster (base 88532ns -> cand 76860ns)
- string_view short_result: 15.165% faster (base 57136ns -> cand
48472ns)
- string long_result: 39.278% faster (base 140969ns -> cand 85600ns)
- string_view long_result: 40.29% faster (base 81808ns -> cand 48847ns)
- string short_result: 14.369% faster (base 86809ns -> cand 74336ns)

Full criterion output:

Subject: [PATCH 599/878] chore: fix `SlidingDistinctCountAccumulator::size()`
 to include budget for distinct values (#23399)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Rationale for this change
Related to https://github.com/apache/datafusion/issues/23393

   ## Rationale for this change

`SlidingDistinctCountAccumulator::size()` returned a flat
`size_of_val(self)` (64 B) regardless of how many distinct values were
held. Since `MemoryPool` reservations trust this value, memory limits
were
silently bypassed for `COUNT(DISTINCT …)` window aggregates — real heap
could reach GBs while the pool reported ~64 B.

  ## What changes are included in this PR?

Fix `SlidingDistinctCountAccumulator::size()` in
`datafusion/functions-aggregate/src/count.rs` to mirror the sibling
`DistinctCountAccumulator::full_size` pattern:

  ```rust
  size_of_val(self)
+ (size_of::<ScalarValue>() + size_of::<usize>()) *
self.counts.capacity()
+ self.counts.keys().map(|k| k.size() - size_of_val(k)).sum::<usize>()
      + self.data_type.size()
      - size_of_val(&self.data_type)
  ```

Accounts for every persistent field of the struct: `self` bytes +
HashMap bucket capacity + per-key inner heap + `DataType` inner heap.
Uses `.capacity()` (not `.len()`) so post-`retract_batch` state still
  reports reserved memory correctly.

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Codecov reports low test coverage for this function, so this PR adds
more SLT tests for it.

The tests were AI-generated, and I manually verified that the results
are correct.

See `Codecov` bot comment -> `☔ View full report in Codecov by Harness`
-> `Indirect Changes` for the updated test coverage.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 603/878] test: improve `isnan` function SQL test coverage
 (#23754)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Codecov reports low test coverage for this function, so this PR adds
more SLT tests for it.

The tests were AI-generated, and I manually verified that the results
are correct.

See `Codecov` bot comment -> `☔ View full report in Codecov by Harness`
-> `Indirect Changes` for the updated test coverage.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 605/878] perf: preserve dictionary encoding for `bit_length`,
 `octet_length`, and `ascii` (#23743)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Follow-up to #22905
- Related to #19458
- Related to #20935

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

String functions normally materialize `Dictionary(K, Utf8)` inputs
before evaluation. This loses the dictionary encoding and applies the
function to every row instead of only the unique dictionary values.

This pr extends the dictionary-preserving implementation from #22905 to
`ascii`, `bit_length`, and `octet_length`.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Preserve dictionary encoding for `ascii`, `bit_length`, and
`octet_length`.
- Preserve return types for regular and nested dictionaries.
- Add slts and Dictionary cardinality benchmarks.

## Are these changes tested?

Yes, covered by SLTs.

We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Yes. These functions now preserve Dictionary encoding in their output:
`Dictionary(K, Utf8) -> Dictionary(K, Int32)`

Subject: [PATCH 606/878] Bump MSRV from `1.88.0` to `1.94.0` (#23632)

see previous bump

- https://github.com/apache/datafusion/pull/18403

honestly my main motivation was i was using a feature from `1.89.0`
apparently for https://github.com/apache/datafusion/pull/23631 and
realized we hadn't bumped this in a while

if we prefer to be more conservative with msrv bumps (i.e. only bump if
a dependency requires it or we see a really useful feature/lib function
in newer versions) then i'm fine with leaving it and altering my PR
above, but in the past we usually kept up to date with bumping our msrv

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Codecov reports low test coverage for this function, so this PR adds
more SLT tests for it.

The tests were AI-generated, and I manually verified that the results
are correct.

See `Codecov` bot comment -> `☔ View full report in Codecov by Harness`
-> `Indirect Changes` for the updated test coverage.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
Codecov reports low test coverage for this function, so this PR adds
more SLT tests for it.

The tests were AI-generated, and I manually verified that the results
are correct.

See `Codecov` bot comment -> `☔ View full report in Codecov by Harness`
-> `Indirect Changes` for the updated test coverage.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 610/878] allow range to satisfy key distribution generally
 (#23680)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23266.
- Part of #22395.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`Partitioning::Range` now satisfies `Distribution::KeyPartitioned`
privately across all operators that require it: aggregates, windows,
TopK, and co-partitioned joins. So now the temporary operator opt-ins
can be consolidated.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Allow compatible `Partitioning::Range` to satisfy
`Distribution::KeyPartitioned` via `Partitioning::satisfaction`
- Remove the temporary range-satisfaction helpers and operator-specific
opt-ins

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,

-->

Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

No, this should not change any exisitng behavior just consolidation

Subject: [PATCH 612/878] refactor: move catalog traits to session crate
 (#23703)

## Which issue does this PR close?

- Addresses one portion of #23678.

## Rationale for this change

This will enable users to create table views using table function over
an existing table in the catalog via FFI. We are currently unable to
access the catalog other than by downcasting a `Session` to
`SessionState`, which is not effective over FFI.

In order to support this, we need to move many trait definitions out of
the `datafusion-catalog` crate and into the `datafusion-session` crate.
There is more discussion in #23678 about why this is necessary.

## What changes are included in this PR?

- Move a variety of catalog traits into `datafusion-session`.
- Add `catalog_list()` function to `Session`.
- Implement `catalog_list()` in `ForeignSession` for FFI users

## Are these changes tested?

New tests are included.

## Are there any user-facing changes?

User guide is updated.

-/// Represents a catalog, comprising a number of named schemas.
-///
-/// # Catalog Overview
-///
-/// To plan and execute queries, DataFusion needs a "Catalog" that provides
-/// metadata such as which schemas and tables exist, their columns and data
-/// types, and how to access the data.
-///
-/// The Catalog API consists:
-/// * [`CatalogProviderList`]: a collection of `CatalogProvider`s
-/// * [`CatalogProvider`]: a collection of `SchemaProvider`s (sometimes called a "database" in other systems)
-/// * [`SchemaProvider`]:  a collection of `TableProvider`s (often called a "schema" in other systems)
-/// * [`TableProvider`]:  individual tables
-///
-/// # Implementing Catalogs
-///
-/// To implement a catalog, you implement at least one of the [`CatalogProviderList`],
-/// [`CatalogProvider`] and [`SchemaProvider`] traits and register them
-/// appropriately in the `SessionContext`.
-///
-/// DataFusion comes with a simple in-memory catalog implementation,
-/// `MemoryCatalogProvider`, that is used by default and has no persistence.
-/// DataFusion does not include more complex Catalog implementations because
-/// catalog management is a key design choice for most data systems, and thus
-/// it is unlikely that any general-purpose catalog implementation will work
-/// well across many use cases.
-///
-/// # Implementing "Remote" catalogs
-///
-/// See [`remote_catalog`] for an end to end example of how to implement a
-/// remote catalog.
-///
-/// Sometimes catalog information is stored remotely and requires a network call
-/// to retrieve. For example, the [Delta Lake] table format stores table
-/// metadata in files on S3 that must be first downloaded to discover what
-/// schemas and tables exist.
-///
-/// [Delta Lake]: https://delta.io/
-/// [`remote_catalog`]: https://github.com/apache/datafusion/blob/main/datafusion-examples/examples/data_io/remote_catalog.rs
-///
-/// The [`CatalogProvider`] can support this use case, but it takes some care.
-/// The planning APIs in DataFusion are not `async` and thus network IO can not
-/// be performed "lazily" / "on demand" during query planning. The rationale for
-/// this design is that using remote procedure calls for all catalog accesses
-/// required for query planning would likely result in multiple network calls
-/// per plan, resulting in very poor planning performance.
-///
-/// To implement [`CatalogProvider`] and [`SchemaProvider`] for remote catalogs,
-/// you need to provide an in memory snapshot of the required metadata. Most
-/// systems typically either already have this information cached locally or can
-/// batch access to the remote catalog to retrieve multiple schemas and tables
-/// in a single network call.
-///
-/// Note that [`SchemaProvider::table`] **is** an `async` function in order to
-/// simplify implementing simple [`SchemaProvider`]s. For many table formats it
-/// is easy to list all available tables but there is additional non trivial
-/// access required to read table details (e.g. statistics).
-///
-/// The pattern that DataFusion itself uses to plan SQL queries is to walk over
-/// the query to find all table references, performing required remote catalog
-/// lookups in parallel, storing the results in a cached snapshot, and then plans
-/// the query using that snapshot.
-///
-/// # Example Catalog Implementations
-///
-/// Here are some examples of how to implement custom catalogs:
-///
-/// * [`datafusion-cli`]: [`DynamicFileCatalogProvider`] catalog provider
-///   that treats files and directories on a filesystem as tables.
-///
-/// * The [`catalog.rs`]:  a simple directory based catalog.
-///
-/// * [delta-rs]:  [`UnityCatalogProvider`] implementation that can
-///   read from Delta Lake tables
-///

+/// Represents a catalog, comprising a number of named schemas.
+///
+/// # Catalog Overview
+///
+/// To plan and execute queries, DataFusion needs a "Catalog" that provides
+/// metadata such as which schemas and tables exist, their columns and data
+/// types, and how to access the data.
+///
+/// The Catalog API consists:
+/// * [`CatalogProviderList`]: a collection of `CatalogProvider`s
+/// * [`CatalogProvider`]: a collection of `SchemaProvider`s (sometimes called a "database" in other systems)
+/// * [`SchemaProvider`]:  a collection of `TableProvider`s (often called a "schema" in other systems)
+/// * [`TableProvider`]:  individual tables
+///
+/// # Implementing Catalogs
+///
+/// To implement a catalog, you implement at least one of the [`CatalogProviderList`],
+/// [`CatalogProvider`] and [`SchemaProvider`] traits and register them
+/// appropriately in the `SessionContext`.
+///
+/// DataFusion comes with a simple in-memory catalog implementation,
+/// `MemoryCatalogProvider`, that is used by default and has no persistence.
+/// DataFusion does not include more complex Catalog implementations because
+/// catalog management is a key design choice for most data systems, and thus
+/// it is unlikely that any general-purpose catalog implementation will work
+/// well across many use cases.
+///
+/// # Implementing "Remote" catalogs
+///
+/// See [`remote_catalog`] for an end to end example of how to implement a
+/// remote catalog.
+///
+/// Sometimes catalog information is stored remotely and requires a network call
+/// to retrieve. For example, the [Delta Lake] table format stores table
+/// metadata in files on S3 that must be first downloaded to discover what
+/// schemas and tables exist.
+///
+/// [Delta Lake]: https://delta.io/
+/// [`remote_catalog`]: https://github.com/apache/datafusion/blob/main/datafusion-examples/examples/data_io/remote_catalog.rs
+///
+/// The [`CatalogProvider`] can support this use case, but it takes some care.
+/// The planning APIs in DataFusion are not `async` and thus network IO can not
+/// be performed "lazily" / "on demand" during query planning. The rationale for
+/// this design is that using remote procedure calls for all catalog accesses
+/// required for query planning would likely result in multiple network calls
+/// per plan, resulting in very poor planning performance.
+///
+/// To implement [`CatalogProvider`] and [`SchemaProvider`] for remote catalogs,
+/// you need to provide an in memory snapshot of the required metadata. Most
+/// systems typically either already have this information cached locally or can
+/// batch access to the remote catalog to retrieve multiple schemas and tables
+/// in a single network call.
+///
+/// Note that [`SchemaProvider::table`] **is** an `async` function in order to
+/// simplify implementing simple [`SchemaProvider`]s. For many table formats it
+/// is easy to list all available tables but there is additional non trivial
+/// access required to read table details (e.g. statistics).
+///
+/// The pattern that DataFusion itself uses to plan SQL queries is to walk over
+/// the query to find all table references, performing required remote catalog
+/// lookups in parallel, storing the results in a cached snapshot, and then plans
+/// the query using that snapshot.
+///
+/// # Example Catalog Implementations
+///
+/// Here are some examples of how to implement custom catalogs:
+///
+/// * [`datafusion-cli`]: [`DynamicFileCatalogProvider`] catalog provider
+///   that treats files and directories on a filesystem as tables.
+///
+/// * The [`catalog.rs`]:  a simple directory based catalog.
+///
+/// * [delta-rs]:  [`UnityCatalogProvider`] implementation that can
+///   read from Delta Lake tables

+### Catalog traits moved to `datafusion-session`
+
+The catalog contract traits now live in the `datafusion-session` crate so they
+can be reached without downcasting a `Session` to `SessionState` (in particular
+across the FFI boundary). The affected traits are `CatalogProviderList`,
+`CatalogProvider`, `SchemaProvider`, `TableProvider`, `TableProviderFactory`,
+and `TableFunctionImpl`. The related `TableFunction` struct also moved.
+
+The `datafusion-catalog` crate re-exports all of them from their new location,
+so paths such as `datafusion::catalog::TableProvider` and
+`datafusion_catalog::CatalogProvider` continue to work unchanged. Most users do
+not need to do anything.
+
+### `Session` gains a required `catalog_list` method
+
+The `Session` trait now requires a `catalog_list` method that returns the
+catalogs registered with the session:
+
+```rust
+fn catalog_list(&self) -> Arc<dyn CatalogProviderList>;
+```
+
+Custom `Session` implementations must add this method. Implementations that do
+not expose a catalog can return the new `EmptyCatalogProviderList`:
+
+```rust
+use std::sync::Arc;
+use datafusion_session::{CatalogProviderList, EmptyCatalogProviderList};
+
+fn catalog_list(&self) -> Arc<dyn CatalogProviderList> {
+    Arc::new(EmptyCatalogProviderList)
+}
+```
+
+See [PR #23703](https://github.com/apache/datafusion/pull/23703) for details.

Subject: [PATCH 613/878]  fix: do not treat concat as preserving
 lexicographical ordering (#23804)

## Which issue does this PR close?
- Closes #23793.

## Rationale for this change
Please check the issue details but main idea is concat does not
guarantee lexicographical ordering

## What changes are included in this PR?
Main change is simply deleting `preserves_lex_ordering` method from
concat and let it fallback to default `false`. Also added relevant tests
and adjusted comments

## Are these changes tested?
Yes adjusted existing and added new tests


## Are there any user-facing changes?
No api changes but there is a behavior change I think on optimization
part for concat

Subject: [PATCH 614/878] refactor(proto): delegate deprecated ProjectionExec
 serde shims to new hooks (#23731)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #23494.

## Rationale for this change

#23495 landed the deprecated `ProjectionExec` compatibility shims
(`try_from_projection_exec` / `try_into_projection_physical_plan`) with
their
original bodies fully duplicated in `datafusion-proto`, even though the
same
wire-format logic now lives in `ProjectionExec::try_to_proto` /
`try_from_proto`
(the #22419 hook pattern). This PR makes those deprecated shims
**delegate** to
the new hooks so the wire format is single-sourced in
`datafusion-physical-plan`
rather than duplicated. This matches the `FilterExec` delegate style in
#23708.
No wire-format change.

## What changes are included in this PR?

- Replace the body of `try_from_projection_exec` with a thin shim that
builds an
  `ExecutionPlanEncodeCtx` from the `codec` + `proto_converter` (via
`ConverterPlanEncoder`) and delegates to `ProjectionExec::try_to_proto`.
- Replace the body of `try_into_projection_physical_plan` with a thin
shim that
builds an `ExecutionPlanDecodeCtx` (via `ConverterPlanDecoder`) and
delegates
to `ProjectionExec::try_from_proto`; the now-unused `projection` param
is
  renamed to `_projection`.
- Drop the now-unused `ProjectionExpr` import.

The `#[deprecated(...)]` attributes and signatures are otherwise
unchanged, and
the live dispatch arms and the `ProjectionExec` hook impls are
untouched.

## Are these changes tested?

Yes — the existing `roundtrip_physical_plan` projection/filter roundtrip
tests
exercise this path and pass (`roundtrip_projection_source`,
`roundtrip_filter_with_fetch`, `roundtrip_filter_with_not_and_in_list`,
and the
full 203-test `roundtrip` suite). `cargo clippy -p datafusion-proto
--all-features -- -D warnings` is clean.

## Are there any user-facing changes?

No. The methods remain `#[deprecated]` with identical signatures and
wire
format; only their internals change.

Subject: [PATCH 615/878] feat: add validating non-Arrow TDigest constructor
 and accessors (#23737)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

No existing issue; this is a small additive API enhancement. Happy to
file a tracking issue if preferred.

<!-- - Closes #. -->

## Rationale for this change

`TDigest` already exposes `to_scalar_state()` / `from_scalar_state()` so
that external systems can persist and restore digest state. However,
that contract requires the caller to pack and unpack the state through a
`ScalarValue::List` of `ScalarValue::Float64` (which `from_scalar_state`
immediately downcasts right back to an `&[f64]`).

A caller that wants to serialize a digest into its own format (this
arose from a production system persisting digests in its own
serialization format) has to construct and then deconstruct
`ScalarValue` lists purely to move data across that boundary. There is
also no way to read the `sum` field or the raw centroids, and no way to
rebuild a digest from primitives.

Crucially, `from_scalar_state` is a *trusting* constructor: its doc
comment states that input not produced by `to_scalar_state()` is
undefined behaviour and may panic. That is the right tradeoff for its
actual use, an intra-query hot path where it is only ever fed the output
of `to_scalar_state()`. It is the wrong tradeoff for an external
persister, which may hand back bytes decoded from its own format: a
subtly corrupt state (unsorted centroids, a zero centroid weight) would
not panic but would produce silently wrong quantiles.

So the point of this API is to **validate at the boundary**:
`try_from_parts` is the validating door for external callers, while
`from_scalar_state` stays exactly as-is as the trusted internal exchange
format. This strengthens, rather than weakens, the separation between
the two.

## What changes are included in this PR?

Three additive, public API additions to `TDigest` (no behavior changes
to existing methods):

- `pub fn try_from_parts(max_size: usize, sum: f64, count: f64, max:
f64, min: f64, centroids: Vec<Centroid>) -> Result<Self,
DataFusionError>` — the validating non-Arrow counterpart to
`from_scalar_state`. It returns an `exec_err!`
(`DataFusionError::Execution`, the crate's convention for invalid
runtime data) if:
- `min` and `max` are both finite but `max < min` (the invariant
`from_scalar_state` asserts);
- the `centroids` are not sorted in non-decreasing order by mean (the
order `centroids()` returns; `from_scalar_state` trusts this without
checking, and `estimate_quantile` relies on it); or
- any centroid weight is not finite and strictly positive.
`estimate_quantile` divides by a centroid's weight, so a zero, negative,
or non-finite weight yields silently wrong (or NaN) results.

  Callers who trust their data can `unwrap()`.
- `pub fn centroids(&self) -> &[Centroid]` — read access to the
centroids (the missing half of the state; the individual `Centroid`
`mean()`/`weight()` accessors already exist).
- `pub fn sum(&self) -> f64` — read access to the `sum` field
(`count`/`max`/`min`/`max_size` accessors already existed; `sum` did
not).

`from_scalar_state` / `to_scalar_state` are unchanged.

## Are these changes tested?

Yes, in the existing `tdigest` test module:

- `test_from_parts_roundtrip` — for digests built from real value
streams (empty, single value, and many values forcing compression), a
digest rebuilt via `try_from_parts` from the public accessors produces a
`to_scalar_state()` equal to the original's, and `estimate_quantile(q)`
that is bitwise-equal across a quantile grid.
- `test_from_parts_equals_original` — for non-empty digests,
`try_from_parts(...)` equals the original under the derived `PartialEq`.
- `test_accessors_agree_with_scalar_state` — `sum()` and `centroids()`
agree with the values packed into `to_scalar_state()`.
- `test_from_parts_rejects_max_less_than_min`,
`test_from_parts_rejects_unsorted_centroids`,
`test_from_parts_rejects_non_positive_weight` — negative tests asserting
each validation returns a descriptive `Err`.

## Are there any user-facing changes?

Yes: new public API on `TDigest` (`try_from_parts`, `centroids`, `sum`).
The change is purely additive: no existing API is modified or removed,
and there are no behavior changes to existing methods.

## Rationale for this change

`unwrap_cast_in_comparison` fails to fold an identity `CAST(col AS
DATE)` on a `Date32` column. Instead of rewriting the predicate to
compare against the bare column, it leaves a residual `Cast(col AS
Date32)` in place, which defeats downstream optimizations (pruning /
filter pushdown) that expect a bare-column comparison.

Reproduction (logical plan for `SELECT * FROM t WHERE cast(d AS date) =
DATE '2024-01-01'`, where `d` is `Date32`): the `cast(d AS Date32)`
survives simplification rather than collapsing to `d`. Note
`arrow_cast(d, 'Date32')` already folds, because the `arrow_cast` UDF's
`simplify()` short-circuits an identity cast; the SQL `CAST ... AS date`
planner plants a real `Expr::Cast` with no such elision, so it reaches
`try_cast_literal_to_type` and is wrongly rejected.

The root cause is in `is_lossy_temporal_cast`
(`datafusion/expr-common/src/casts.rs`):

```rust
(is_date_type(from_type) && to_type.is_temporal())
    || (is_date_type(to_type) && from_type.is_temporal())
```

For an identity `Date32 -> Date32` cast this evaluates to `true &&
true`, because `DataType::is_temporal()` is true for both `Date32` and
`Date64`. The identity cast is therefore misclassified as a lossy
temporal cast, `try_cast_literal_to_type` returns `None`, and
`unwrap_cast_in_comparison` leaves the cast in the plan.

## What changes are included in this PR?

Short-circuit an identity cast as non-lossy at the top of
`is_lossy_temporal_cast`:

```rust
if from_type == to_type {
    return false; // an identity cast never changes comparison semantics
}
```

This is deliberately limited to *identical* types, not "any
date-to-date". `Date32` counts days while `Date64` counts milliseconds,
but `try_cast_numeric_literal` uses `mul = 1` for both, so allowing a
`Date32 <-> Date64` unwrap would convert units incorrectly. The
`from_type == to_type` identity guard is the exact correct scope, and
`Date32 <-> Date64` remains blocked.

## Are these changes tested?

Yes. The PR is structured as a test-driven, stacked sequence so the
effect of the fix is visible in the diff:

1. **`test: characterize identity Date cast in comparison unwrapping`**
— adds an SLT test to `simplify_expr.slt` (`explain select d from dates
where cast(d as date) = DATE '2024-01-01'`) whose assertion records the
*current, buggy* output: the logical plan keeps the residual `Filter:
CAST(dates.d AS Date32) = Date32(...)`. Passes on `main`.
2. **`fix: unwrap identity Date cast in comparison unwrapping`** — the
production change plus two `expr-common` unit tests:
- `test_try_cast_identity_date_allowed` — identity `Date32 -> Date32` /
`Date64 -> Date64` now fold (`try_cast_literal_to_type` returns `Some`),
and `is_lossy_temporal_cast` reports them non-lossy.
- `test_try_cast_date32_date64_still_blocked` — `Date32 <-> Date64`
stays lossy/blocked (guards the units caveat above, which SLT can't
easily express).

At this commit the SLT test is intentionally red, proving it exercises
the bug.
3. **`test: update identity Date cast assertion to folded plan`** —
updates the SLT assertion to the corrected `Filter: dates.d =
Date32(...)`. The one-line diff is the observable effect of the fix.

`cargo fmt --check` and `cargo clippy -D warnings` are clean on the
changed crate; `datafusion-expr-common` and the `simplify_expr`
sqllogictest pass.

## Are there any user-facing changes?

No API changes. Queries with `CAST(date_col AS DATE)` predicates on
`Date32` columns simplify to bare-column comparisons, which can enable
additional pruning/pushdown. No behavioral change to query results.

Subject: [PATCH 617/878] fix: reject nested aggregate functions (e.g.
 `sum(sum(x))`) during logical planning (#23813)

## Which issue does this PR close?

- Closes #23812.

## Rationale for this change

Nested aggregate calls such as `sum(sum(x))` were accepted by the
planner and produced a
`LogicalPlan::Aggregate` whose `aggr_expr` contained an inner
`Expr::AggregateFunction` as a
function *argument*. That plan has no physical equivalent, so the query
failed late, during
physical planning, with:

```
This feature is not implemented: Physical plan does not support logical expression
AggregateFunction(AggregateFunction { func: AggregateUDF { inner: Sum { signature: Signature { ... } } }, ... })
```

Two problems: the query should be rejected at planning time, and the
error text dumps the `Debug`
formatting of a `Signature` (including the full coercion table) without
ever mentioning nesting,
the offending function, or the offending column.

Two neighbouring classes of illegal nesting (raised in review) fail
exactly the same way, so this
PR covers them too:

```sql
SELECT sum(sum(x) OVER ()) FROM t;                          -- window call inside an aggregate
SELECT sum(sum(x) OVER ()) OVER () FROM t;                  -- nested window calls
SELECT row_number() OVER (ORDER BY row_number() OVER ());   -- nested window calls
```

PostgreSQL rejects all three at parse/analysis time with `aggregate
function calls cannot be
nested`, `aggregate function calls cannot contain window function calls`
and `window function calls
cannot be nested` respectively; this PR uses the same wording per case.

## What changes are included in this PR?

- One crate-private `check_aggregate_and_window_nesting`, which walks
the expressions and, for every
aggregate or window call it finds, rejects an illegally nested call
below it (in the arguments,
`FILTER`, `PARTITION BY` or `ORDER BY`). Which pairs are illegal, and
the message for each, live
  in a single match over the (outer, inner) pair.
- `Aggregate::try_new` and `Window::try_new` call it, so both the SQL
path and the
`DataFrame`/`LogicalPlanBuilder` path are covered, and the failure
happens while the logical plan
  is built.
- The errors name both expressions and carry a `Diagnostic` (with a span
pointing into the original
  SQL and a help message), for example:

```
Error during planning: Aggregate function calls cannot be nested:
'sum(t.column2)' is nested inside 'sum(sum(t.column2))'
```

The legal cases from the issue are unaffected, as they do not nest one
call inside another of a
restricted kind: a scalar function over an aggregate (`abs(sum(x))`), a
window function over an
aggregate (`sum(sum(x)) OVER ()`, which plans as `WindowAggr` over
`Aggregate`), and an aggregate
over an aggregate or window result computed in a subquery.

## Are these changes tested?

Yes:

- unit tests for the check (arguments, `FILTER`, `ORDER BY`,
window-in-aggregate, window-in-window,
and the legal window-over-aggregate case) in
`datafusion/expr/src/utils.rs`;
- `LogicalPlanBuilder::aggregate` and `LogicalPlanBuilder::window` tests
covering the non-SQL path;
- SQL planner tests for `SELECT`, `GROUP BY` and `HAVING`, for
window-in-aggregate and nested
windows, plus a test asserting the `sum(sum(x)) OVER ()` plan is
unchanged;
- diagnostic tests asserting the span and help message;
- sqllogictests in `aggregate.slt` covering every row of the table in
the issue plus the window
  cases.

## Are there any user-facing changes?

Queries with these nestings now fail during planning with an actionable
error instead of failing
during physical planning with a `NotImplemented` error. No previously
working query changes
behavior.

No new public API: the check is `pub(crate)`, since `Aggregate::try_new`
and `Window::try_new`
enforce the invariant for every way of building those nodes.

Changed lines are at 99.3% coverage (`cargo llvm-cov`; the one uncovered
line is a formatting
artifact inside a passing test), and `cargo mutants --in-diff` generates
11 mutants of which 4 are
unviable and all 7 viable ones are killed.

Subject: [PATCH 618/878] refactor(proto): migrate SortExec and
 SortPreservingMergeExec serde (#23794)

## Which issue does this PR close?

 - Closes #23505.

 ## Rationale for this change

Part of epic #23494. Moves `SortExec` and `SortPreservingMergeExec`
protobuf serialization from central dispatch.

 ## What changes are included in this PR?

Add protobuf serialization and deserialization to the physical plan
implementations and deprecate the corresponding central proto methods.
The wire format remains unchanged.

 ## Are these changes tested?

 Yes, existing round-trip tests cover these plans.

 ## Are there any user-facing changes?

 Existing methods are deprecated with no immediate API change.

Subject: [PATCH 619/878] refactor(proto): migrate UnnestExec serde (#23739)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23510.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
The central protobuf dispatcher must know every built-in execution plan,
which separates UnnestExec serialization from the type that owns it.

Move encoding and decoding to plan-local hooks while retaining the
deprecated helpers as compatibility wrappers. Extend roundtrip coverage
to include non-default unnest options.



## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 620/878] chore: remove Github filter `status:success` for
 `pending PR` shield (#23846)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

The Github `status:success` is tricky and confirmed to work not as
expected with GH Actions, actually leading to filter out more PRs than
needed. Remove the filter

src="https://github.com/user-attachments/assets/e1099e04-3b93-420b-a538-fceb4863e299"
/>


<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

 ## Rationale for this change

Part of epic #23494. Moves `GlobalLimitExec` and `LocalLimitExec`
protobuf serialization from central dispatch.

 ## What changes are included in this PR?

 Add new proto functions in physical plan and deprecate proto ones.

 ## Are these changes tested?

 Yes, existing round trip tests pass.

 ## Are there any user-facing changes?

 Existing methods are deprecated with no immediate API change.

Subject: [PATCH 622/878] Add setter for `TaskContext::task_id` (#23837)

## Which issue does this PR close?

Closes #22072

## Rationale for this change

Without a way to set `TaskContext::task_id` the field is a bit
pointless. This MR adds a way to set the field.
This does not automatically make the field useful for correlation
purposes (as hinted at by the linked issue) since it's not filled in
anywhere yet, but at least the capability is already there.

## Are these changes tested?

Not sure how to meaningfully test this

## Are there any user-facing changes?

No

Subject: [PATCH 623/878] refactor(proto): migrate RepartitionExec serde
 (#23792)

## Which issue does this PR close?

 - Closes #23504.

 ## Rationale for this change

Part of epic #23494. Moves `RepartitionExec` protobuf serialization from
central dispatch.

 ## What changes are included in this PR?

 Add new proto functions in physical plan and deprecate proto ones.

 ## Are these changes tested?

 Yes, existing round trip tests pass.

 ## Are there any user-facing changes?

 Existing methods are deprecated with no immediate API change.

Subject: [PATCH 624/878] refactor(proto): migrate CrossJoinExec and
 NestedLoopJoinExec serde (#23834)

## Which issue does this PR close?

 - Closes #23506.

 ## Rationale for this change

Part of epic #23494. Moves `CrossJoinExec` and `NestedLoopJoinExec`
protobuf serialization from central dispatch.

 ## What changes are included in this PR?

 Add new proto functions in physical plan and deprecate proto ones.

 ## Are these changes tested?

 Yes, existing round trip tests pass.

 ## Are there any user-facing changes?

 Existing methods are deprecated with no immediate API change.

Subject: [PATCH 625/878] fix: array_any_value returns NULL for empty list
 elements (#23775)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23773.

## Rationale for this change

`array_any_value` reads the wrong value (or panics) when its input list
column
contains a non-null **empty** (length-0) element.

`general_array_any_value` guards null and all-null elements, but a
non-null
empty element falls through to the no-nulls branch, which
unconditionally reads
`values[start]`:

- **interior empty list** → reads `values[start]`, i.e. the *next*
element's
  value (silently wrong data)
- **trailing empty list** (`start == values.len()`) → out-of-bounds
slice →
  panic `range end index N out of range for slice of length N-1`

The panic is easy to trigger in practice when the `array_any_value`
output flows
into a hash `RepartitionExec` (e.g. the value is used as an equi-join
key):
repartitioning slices batches so an empty element can land at the end of
a
values buffer, tripping the out-of-bounds read on a spawned task.

## What changes are included in this PR?

Guard the empty case explicitly in `general_array_any_value` — an empty
list has
no value to take, so the result is `NULL`.

Sibling functions in `extract.rs` were audited and are already safe:
`array_element` bounds-checks the index against `len`; `array_slice` /
`array_pop_front` / `array_pop_back` guard `len == 0`.

## Are these changes tested?

Yes:

- Kernel-level regression tests for `general_array_any_value`: an
interior empty
element (previously wrong value) and a trailing empty element
(previously
  panic).
- `array_any_value.slt` cases covering `List` and `LargeList` with
interior and
  trailing empty elements.

## Are there any user-facing changes?

`array_any_value` now returns `NULL` for an empty list element instead
of
returning the next element's value or panicking the query. No API
changes.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue, then this section is not needed.
Clearly explaining why changes are proposed helps reviewers understand
your changes and offer better suggestions.
-->

This PR implements larger-than-memory execution for ordered partial and
ordered final aggregation. These two modes are implemented first
because:

- #22710 splits ordered and unordered aggregation into separate
implementations.
- Unordered aggregation internally reuses ordered aggregation for its
larger-than-memory execution logic. So larger-than-memory support for
ordered aggregation become the groundwork for other aggregation modes.

The high-level plan for two-stage ordered hash aggregation is:

```
AggregateExec(mode=final, ordered)
--RepartitionExec(hash)
----AggregateExec(mode=partial, ordered)
```

#### Group keys are fully ordered (input ordered by `a, b`; query uses
`GROUP BY a, b`)

Execution must use bounded memory because only one group is active at
any given time. Therefore, the implementation simply returns an
execution error if a memory reservation fails.

#### Group keys are partially ordered (input ordered by `a`; query uses
`GROUP BY a, b`)

At any given time, we must hold all groups for a particular value of `a`
in memory, so it is possible to run out of memory. This is handled as
follows:

If the partial aggregate runs out of memory, it directly materializes
the accumulated groups as aggregate states and emits them early to the
final stage.

The final aggregate continues aggregating until its memory budget is
reached, then:

1. Sorts the aggregated batches by the group keys and writes them to
disk.
2. Repeats this process until the input is exhausted.
3. Constructs a sort-preserving merge stream over all spill files.
4. Constructs an `OrderedFinalAggregateStream` using the sort-preserving
merge stream as its input. The new stream's group keys are fully
ordered, whereas those of the original stream were only partially
ordered. It then evaluates this ordered stream to produce the final
result.

### Design Tradeoffs
Note that the same implementation is currently shared by two execution
paths, controlled by flags: aggregation with fully ordered group keys
and aggregation with partially ordered group keys. This is not an ideal
pattern. However:

- Fully ordered aggregation can later be split into a separate
implementation with potentially more aggressive optimizations—for
example, it does not require a hash table. The the current
implementation only have to handle partially-ordered cases.
- For now, the behavior remains consistent with the original
implementation, allowing us to complete the migration sooner.



## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
The core changes are in `ordered_partial_stream.rs` and
`ordered_final_stream.rs`, for the above algorithm. See code comments
for implementation details.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
6. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
After implementing this change, I checked the coverage using `cargo
llvm-cov` and found that this feature was supported by the original
implementation but was not covered by either regular tests or fuzz
tests. This is a bit of a horror story.

I think the old implementation is heavily multiplexed, so its overall
line coverage is probably good. However, spilling for ordered
aggregation follows a specific execution path that was never exercised.

Therefore, this PR adds `slt` test coverage. I also think we need more
fuzzing cases (filed https://github.com/apache/datafusion/issues/23658)


## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

+/// For partially sorted input, spilling works as follows:
+///
+/// - Reserve the table footprint plus one `u32` sort index per buffered group. The
+///   extra index array is used in later sorting before spilling.
+/// - On memory pressure, materialize all group states into one batch.
+/// - Use [`IncrementalSortIterator`] to compute the full-batch index, then
+///   materialize and write one sorted `batch_size` slice at a time. The original
+///   batch and full index remain live until the run is written.
+/// - After input ends, merge the sorted runs and replay them through a fully
+///   ordered final aggregate stream.

+///
+/// - Input order: `a`
+/// - `GROUP BY`: `a, b`
+///
+/// If one `a` value contains many distinct `b` values, the table may accumulate

+/// - `OrderedPartialAggregateStream`: On reservation failure, it emits all current
+///   intermediate states downstream and resets the table. The final stage can
+///   merge repeated `(a, b)` state rows, so no disk spill is required.
+/// - `OrderedFinalAggregateStream`: It cannot emit incomplete final results. On
+///   reservation failure, it sorts the current intermediate states by the complete
+///   group key and spills them as one run. After the input ends, it spills any
+///   remaining states, performs a sort-preserving merge of all runs, and feeds the

Subject: [PATCH 629/878] perf: optimize LEAD/LAG IGNORE NULLS evaluation
 (#23711)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- N/A

## Rationale for this change

The whole-partition evaluation path for `LEAD` and `LAG` with `IGNORE
NULLS` currently collects every valid row index, performs a binary
search for every output row, converts every selected value to a
`ScalarValue`, and finally rebuilds an Arrow array from those scalars.

This makes index selection `O(n log m)` for `n` rows and `m` non-null
rows, and the per-row scalar materialization is particularly expensive
for strings and nested values.

A local Criterion microbenchmark with 100,000 rows and 50% nulls
measured the following speedups across the tested offsets:

| Data type | Speedup |
| --- | ---: |
| `Int64` | 6.7–6.9x |
| `Utf8View` | 10.5–11.6x |
| `List` | 21.7–21.8x |

## What changes are included in this PR?

- Generate nullable Arrow gather indices with a single linear scan and
bounded `VecDeque` state instead of collecting all valid indices and
binary-searching for every row.
- Materialize the result with Arrow's `take` kernel.
- Use Arrow's `zip` kernel to fill non-null default values without
constructing one `ScalarValue` per row.
- Keep dictionary arrays with non-null defaults on scalar
materialization because `zip` concatenates dictionaries and can overflow
bounded dictionary key types.

The index generation and output materialization are now `O(n)`. There
are no public API changes.

## Are these changes tested?

Yes.


## Are there any user-facing changes?

No. This changes the implementation of whole-partition `LEAD`/`LAG ...
IGNORE NULLS` evaluation without changing the SQL behavior or public
API.

Subject: [PATCH 630/878] refactor(proto): migrate symmetric hash join serde
 (#23736)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23509.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
SymmetricHashJoinExec serialization still depends on centralized plan
dispatch, keeping its join, streaming-mode, and ordering wire logic
outside the plan that owns the state. The retained compatibility helpers
also duplicate that logic and can drift from normal dispatch.

Move encoding and decoding behind the plan's ExecutionPlan hooks, route
central dispatch through them, and reduce the deprecated helpers to thin
adapters. Preserve explicit enum and optional-ordering representations,
and expand round-trip coverage across the serialized join state.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 631/878] feat: migrate EmptyExec and PlaceholderRowExec to
 ExecutionPlan proto hooks (#23784)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23501 .

## Rationale for this change

Migrates the `EmptyExec` and `PlaceholderRowExec` leaf plans while
preserving the existing protobuf wire format.


<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
- Implement `ExecutionPlan::try_to_proto` for `EmptyExec` and
`PlaceholderRowExec`.
- Add plan-specific `try_from_proto` implementations.
- Route protobuf encoding and decoding through the new hooks.
- Keep the deprecated helper methods as compatibility shims.

## Are these changes tested?

yes
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Hi @andygrove , would you be willing to review this PR when you have
time? Thanks!

Subject: [PATCH 632/878] fix: grouped first_value/last_value FILTER excludes
 NULL predicate rows (#23707)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22666

## Rationale for this change

Under SQL aggregate `FILTER` semantics, a row passes only when the
predicate evaluates to `true`; rows where the predicate is `null` must
be excluded. Grouped `first_value` / `last_value` checked only
`BooleanArray::value(idx)`, without checking validity, so a NULL
predicate row whose underlying value bit is set (as produced by
comparison kernels, e.g. `null::int < 1`) was treated as passing:

```sql
SELECT g, first_value(a ORDER BY a) FILTER (WHERE b < 1) AS fv
FROM (VALUES (0, 10, CAST(NULL AS INT)), (0, 20, 2)) AS t(g, a, b)
GROUP BY g;
-- returned fv = 10, must return fv = NULL
-- (row 1: b < 1 is NULL; row 2: b < 1 is FALSE — no row satisfies `true`)
```

## What changes are included in this PR?

`datafusion/functions-aggregate/src/first_last.rs`, in
`FirstLastGroupsAccumulator::get_filtered_extreme_of_each_group` (shared
by `first_value` and `last_value`, and by both the `update_batch` and
`merge_batch` paths):

- `passed_filter` now requires `is_valid(idx) && value(idx)` (the
`Some(true)` semantics), matching the convention already used by
`variance.rs` / `correlation.rs`.
- The `is_set_arr` read gets the same validity check. This is *not* only
an internal bitmap: `convert_to_state` stores the user FILTER clause
(including its nulls) in the last state column, so on the merge path
(e.g. skip-partial-aggregation) NULL predicate rows were likewise
treated as set. Verified with a forced skip-partial run (100k unique
groups, all-NULL predicates): 83,616 groups were incorrectly assigned
non-NULL values before the fix, 0 after. For genuine internal bitmaps
(no nulls) the added check is trivially true, so behavior there is
unchanged.

Regression coverage:
- sqllogictest (`aggregate.slt`): the issue reproducer, the `last_value`
counterpart, mixed TRUE/FALSE/NULL predicates, all-TRUE and no-FILTER
controls, the (already correct) non-grouped path, and a window-function
no-regression case.
- Unit tests: `test_group_acc_filter_null_predicate` (update path) and
`test_group_acc_merge_null_is_set` (merge path via `convert_to_state` →
`merge_batch`), both constructing `BooleanArray`s whose null slots carry
a set value bit.

## Are these changes tested?

Yes — see above. Verified `./dev/rust_lint.sh`, `cargo test -p
datafusion-functions-aggregate --lib`, the `aggregate`/`window`
sqllogictest files, and `datafusion-cli` end-to-end (grouped
first/last_value now return NULL for the issue reproducer;
mixed-predicate and non-grouped results unchanged).

Also audited the rest of `functions-aggregate` for the same
validity-blind pattern: shared helpers (`nulls.rs::filter_to_validity`,
`accumulate.rs`, `prim_op.rs`, `count.rs`, `array_agg.rs`,
`variance.rs`, `correlation.rs`) already handle validity correctly, and
non-grouped paths pre-filter with arrow's `filter` kernel (which drops
NULL predicate rows), so no other aggregate needs changes.

## Performance

`functions-aggregate/benches/first_last.rs` was run against `main`. The
added checks are one validity-bit test per row on the grouped path;
measured deltas were within the machine's noise floor (±5% on unchanged
`filter=false` cases). A variant hoisting the null check out of the row
loop showed no measurable benefit beyond noise, so the simple idiomatic
form is kept.

## Are there any user-facing changes?

Only the bug fix: grouped `first_value`/`last_value` with a nullable
`FILTER` predicate now correctly exclude NULL-predicate rows, matching
SQL semantics and the behavior of other aggregates. No API or
configuration changes.

Subject: [PATCH 633/878] Unwrap widening Date32 -> Date64 casts in comparison
 predicates (#23729)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- N/A. Small, self-contained enhancement to `unwrap_cast_in_comparison`;
happy to file a tracking issue if preferred.

## Rationale for this change

`unwrap_cast_in_comparison` could not unwrap a cast between the two date
types, so a predicate like `CAST(date32_col AS Date64) <op> <date64
literal>` never folded onto the bare column. Folding it lets the literal
be compared against the unmodified column, keeping predicate pushdown /
pruning effective on date columns.

There were two coupled causes in `try_cast_literal_to_type`
(`datafusion/expr-common/src/casts.rs`):

1. `try_cast_numeric_literal` scaled both `Date32` and `Date64` literals
by the same target multiplier (`mul = 1`). But `Date32` counts **days**
since the epoch while `Date64` counts **milliseconds**, so a cross
conversion needs a factor of `MILLISECONDS_IN_DAY` (86_400_000).
2. `is_lossy_temporal_cast` classified every `Date <-> temporal` pair as
lossy, which swept in `Date32 <-> Date64` and blocked the unwrap
outright.

The reverse direction is subtle and unsound if handled naively:
narrowing a `Date64` **column** down to `Date32` truncates milliseconds
to the day (many-to-one), so `CAST(date64 AS Date32) = <day>` matches
any millisecond within that day. arrow-rs does not require `Date64`
values to be whole-day (apache/arrow-rs#5288), so the column may carry
sub-day values the planner cannot see, and unwrapping would drop those
rows. That direction is therefore explicitly blocked.

## What changes are included in this PR?

- Relax `is_lossy_temporal_cast` so a date-to-date (and identity) cast
is not pre-classified as lossy; per-value exactness is enforced
downstream.
- Add `scale_date_literal` with exact-only semantics: `Date32 -> Date64`
multiplies by `MILLISECONDS_IN_DAY` (overflow-guarded with checked
arithmetic); `Date64 -> Date32` divides only on a whole-day boundary and
otherwise returns `None`. This mirrors the existing Decimal scaling path
in the same function.
- Add `is_date_narrowing_cast` and block the narrowing `Date64 ->
Date32` column cast in the two logical-optimizer gates (comparison and
in-list) **and** in the physical-expr simplifier, mirroring
`is_timestamp_precision_narrowing_cast`. The physical-expr guard is
required for soundness on the pruning / row-group-filter path (verified
by a unit test that fails without it); the widening `Date32 -> Date64`
column cast is injective and stays supported.

Scope is intentionally limited to `Date32 <-> Date64` scaling, the
narrowing gate, and tests.

## Are these changes tested?

Yes, at two levels.

**End-to-end (`datafusion/sqllogictest/test_files/simplify_expr.slt`)**
— the PR is structured as three commits so the behavior change is
legible in the diff:

1. `test:` characterizes current behavior (passes on unmodified `main`):
neither direction is unwrapped, results are correct. The fixture stores
sub-day and pre-epoch `Date64` values on purpose.
2. `feat:` applies only the code change; the recorded widening `EXPLAIN`
plans now fail intentionally.
3. `test:` regenerates the expectations. The commit-3 diff is exactly
the widening plans flipping from `CAST(d32 AS Date64) <op> Date64(..)`
to `d32 <op> Date32(..)`; **every result row and every narrowing plan is
byte-identical**, which is the soundness proof. Coverage includes
`=`/`<`/`<=`/`>`/`>=`/`IN`, whole-day vs sub-day literals (the latter
yields zero rows and is left as-is), the narrowing soundness case (the
noon row is still returned), pre-epoch dates (arrow's toward-zero
truncation is pinned), and NULL three-valued logic.

**Unit** — `scale_date_literal` exactness and `i32::MIN`/`i32::MAX`
overflow, `is_date_narrowing_cast`, the relaxed `is_lossy_temporal_cast`
date-pair behavior, and the physical-expr narrowing guard.

`cargo fmt --check` is clean, `cargo clippy -p datafusion-expr-common --
-D warnings` passes, and the full sqllogictest suite passes.

## Are there any user-facing changes?

No public API changes. The optimizer now additionally rewrites widening
`Date32 -> Date64` cast comparisons where it previously left them
untouched; results are unchanged, plans are simplified. Narrowing
`Date64 -> Date32` cast comparisons are deliberately left as-is.

## Note for reviewers

The open PR #23727 adds the `if from_type == to_type { return false }`
identity guard to this same function. This PR is based independently on
`main` and includes that identity line as part of the clean gate shape
here, so depending on merge order the two may need a trivial rebase
where those lines overlap.

Subject: [PATCH 634/878] test (slt): add memory-limited aggregation
 sqllogictests (#23838)

## Which issue does this PR close?

- Part of #22710.

## Rationale for this change

There's almost no slt coverage for grouped aggregation under a memory
limit, where the aggregate spills to disk and re-groups the spilled
state. #23657 covers the ordered path & this covers the unordered/hash
path.

## What changes are included in this PR?

- Adds `aggregate_memory_limit.slt` in which the high-cardinality "GROUP
BY" is run under a 1M limit, so the hash aggregate spills. The group key
is scrambled with `(v * 7) % 100000` (a bijection, so still 100000
groups) to keep the input unsorted; otherwise it takes the streaming
path and never spills.
- Scoped to a single partition (`target_partitions = 1`), so the spill
happens in one aggregate operator with no repartition.
- Cases cover different accumulator states: single-column, multi-column,
count(DISTINCT), sum/min/max, avg (widening), array_agg (growable).

## Are these changes tested?

This PR is tests. All pass locally.

## Are there any user-facing changes?

No.

+# = 1, so it's a bijection over 1..100000. Still 100000 groups, just unsorted,
+# so the hash table grows and spills.

+# row. sum(1..100000) = 5000050000, and every v lands in one group, so the

Subject: [PATCH 635/878] feat: add OR pre-selection short-circuit (#22979)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #22342.

## Rationale for this change

`BinaryExpr` already uses pre-selection for `AND` when only a small set
of LHS rows can affect the final result. This adds the matching
optimization for `OR` when most LHS rows are already true.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

This PR extends pre-selection short-circuiting to `OR`.

For `OR`, the RHS is evaluated only for rows where the LHS is false.
Rows where the LHS is true are filled directly as true. The existing
`AND` path is kept and the scatter logic is shared.

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

No Public API Change

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 636/878] perf: optimize `find_in_set` (up to 24x faster)
 (#23460)

## Which issue does this PR close?

N/A

## Rationale for this change

Improve performance of existing expression.

## What changes are included in this PR?

Replace per-row O(set_len) linear scan in find_in_set's constant-list
path with a one-time HashMap lookup (threshold-guarded so short lists
keep the linear scan), giving O(1) per-row probing for large sets.

## Are these changes tested?

Existing tests + new tests

Benchmark (criterion):

- long_list_256: 95.827% faster (base 1246412ns -> cand 52009ns) - ~24x
faster
- short_list_4: 2.13% faster (base 64343ns -> cand 62972ns)
- long_list_64: 88.562% faster (base 422083ns -> cand 48276ns)


## Are there any user-facing changes?

No

Subject: [PATCH 637/878] fix: NOT IN with NULL subquery returns wrong results
 under SortMergeJoin (#22810)

## Problem

`NOT IN (subquery)` is a null-aware anti join: when the subquery yields
a NULL the predicate is never TRUE, so the query must return zero rows.
With `prefer_hash_join = false` and multiple partitions, the planner
routed the null-aware anti join to `SortMergeJoinExec`, which is not
null-aware, so it returned wrong results. HashJoin (the default) was
already correct.

## Proof

```sql
set datafusion.optimizer.prefer_hash_join = false;
create table t1(x int) as values (1);
create table t2(y int) as values (NULL);
select x from t1 where x not in (select y from t2);
```

Expected 0 rows (the subquery contains a NULL). Before this change it
returned `1`. With `prefer_hash_join = true` it correctly returned 0
rows. `EXPLAIN` showed the wrong config selecting `SortMergeJoinExec:
join_type=LeftAnti`.

## Solution

The planner already requires null-aware joins to use the CollectLeft
HashJoin, and the HashJoin branch guards on `!null_aware`. The
SortMergeJoin branch was missing the same guard, so this adds `&&
!*null_aware` to it. Null-aware anti joins now fall through to the
CollectLeft HashJoin regardless of `prefer_hash_join`.
`SortMergeJoinExec` has no `null_aware` parameter and cannot honor these
semantics.

Added a regression test in `subquery.slt` (under `prefer_hash_join =
false`) covering both a null-containing subquery (zero rows) and a
null-free subquery (normal anti join). All 61 SortMergeJoin unit tests
pass.

Subject: [PATCH 638/878] Remove `GroupsAccumulator::supports_convert_to_state`
 and require `convert_to_state` (#23489)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23081.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Following #23275, all `GroupsAccumulator` implementations now provide
`convert_to_state`.

The `supports_convert_to_state` capability flag is therefore no longer
needed.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Make `GroupsAccumulator::convert_to_state` a required trait method.
- Remove `GroupsAccumulator::supports_convert_to_state` and its
implementations.
- Remove the corresponding capability checks from hash aggregation.
- Simplify skip-partial aggregation to use the required
`convert_to_state` implementation directly.
- Add a regression test covering the partial hash aggregation skip path.
- Document the breaking trait change in the 55.0.0 upgrading guide.

- Remove `FFI_GroupsAccumulator::supports_convert_to_state`. This
changes the FFI ABI layout, so providers and consumers must be rebuilt
against DataFusion 55.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes. Added a regression test verifying that skip-partial aggregation
uses the required `convert_to_state` implementation without a capability
flag.

Existing physical-plan and FFI tests continue to pass.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Yes. This is a breaking Rust API change for external `GroupsAccumulator`
implementations:

- `convert_to_state` must now be implemented.
- `supports_convert_to_state` should be removed.

The migration is documented in the 55.0.0 upgrading guide.

The `FFI_GroupsAccumulator` layout has changed. FFI providers and
consumers must be rebuilt against DataFusion 55 and must not exchange
this struct with older major versions.

+### `GroupsAccumulator::convert_to_state` is now required
+
+`datafusion_expr_common::groups_accumulator::GroupsAccumulator::convert_to_state`
+no longer provides a default implementation, and the
+`GroupsAccumulator::supports_convert_to_state` capability method has been
+removed. All `GroupsAccumulator` implementations must now support converting
+input batches directly to intermediate aggregate state.
+
+**Who is affected:**
+
+- Users with custom `GroupsAccumulator` implementations.
+- FFI providers and consumers that use `FFI_GroupsAccumulator`.
+
+**Migration guide:**
+
+Custom `GroupsAccumulator` implementations must now provide their own
+`convert_to_state` implementation.
+
+Delete `supports_convert_to_state` implementations because `convert_to_state`
+is now required:
+
+```diff
+- fn supports_convert_to_state(&self) -> bool {
+-     true
+- }
+```
+
+The `supports_convert_to_state` field has also been removed from
+`datafusion_ffi::udaf::groups_accumulator::FFI_GroupsAccumulator`, changing its
+ABI layout. Rebuild both FFI providers and consumers against DataFusion 55, and
+do not exchange this struct with libraries built against older major versions.
+
+See [issue #23081](https://github.com/apache/datafusion/issues/23081) for details.

<ul>
<li>Fixed a remote memory exhaustion DoS vulnerability (2b2abd45).</li>
</ul>
<p>A high volume of tiny fragments and data chunks could be sent by a
peer, using
modest network traffic, to crash a <code>ws</code> server or client due
to OOM.</p>

const data = Buffer.alloc(1);
const options = { fin: false };

Subject: [PATCH 642/878] fix: align physical CASE nullability through casts
 (#23844)

## Rationale for this change

Logical `CASE` nullability unwraps null preserving casts before
analyzing guarded branches, but physical `CASE` nullability did not.
Type coercion could therefore produce conflicting schemas and cause
valid aggregation queries to fail during planning

Subject: [PATCH 643/878] test: add functional_dependencies.slt covering
 functional dependency driven optimizations (#23821)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

This PR adds test coverage rather than closing an issue. It documents
the current behavior of these bugs so that fixing them shows up as a
test change:

- https://github.com/apache/datafusion/issues/23634
- https://github.com/apache/datafusion/issues/23818
- https://github.com/apache/datafusion/issues/23819
- https://github.com/apache/datafusion/issues/23820

## Rationale for this change

While reviewing #23636 @neilconway and I kept coming up with more
examples of bad plans, and it was not obvious which of the surrounding
wrong answers were pre-existing and which the PR introduced.

## What changes are included in this PR?

A new `datafusion/sqllogictest/test_files/functional_dependencies.slt`
with one section per consumer of functional dependencies:

1. `ReplaceDistinctWithAggregate` — removing `DISTINCT`
2. `eliminate_duplicated_expr` — dropping trailing `ORDER BY` keys
3. `optimize_projections` — dropping `GROUP BY` expressions
4. `add_group_by_exprs_from_dependencies` — selecting non-grouped
columns
5. `GROUP BY` derived keys on the NULL-padded side of an outer join

Cases that currently return wrong answers are labelled `BUG` with the
expected
result and a link to the issue:

| Case | Symptom | Issue |
| --- | --- | --- |
| 1.2 | `DISTINCT` over a nullable `UNIQUE` column returns both `NULL`
rows | #23634 |
| 2.2 | `ORDER BY x, y` drops the `y` key, so the `NULL` rows come back
unordered | #23818 |
| 3.2 | `GROUP BY x, y` drops `y`, merging the two `NULL` groups and
losing a row | #23819 |
| 4.2 | `SELECT x, y ... GROUP BY x` returns two rows for the `x = NULL`
group | #23820 |


## Are these changes tested?
CI
## Are there any user-facing changes?

No.

+# Tests for functional dependencies
+# (`datafusion/common/src/functional_dependencies.rs`)
+#
+# A functional dependency records that one set of columns (the *determinant*)
+# determines the values of the others. DataFusion derives them from PRIMARY
+# KEY / UNIQUE constraints and from GROUP BY keys, and four optimizer rules
+# consume them to remove redundant work, each tested here in a different section.
+#
+# NULL handling is (as always) important:
+#
+#   * A PRIMARY KEY is unique AND not nullable.
+#   * A `UNIQUE` constraint permits *multiple NULL rows*, because NULLs
+#     compare distinct.
+#
+# It is important not to mix `UNIQUE` columns with `DISTINCT` or `GROUP BY`,
+# which treat NULLs as equal and can produce wrong answers.

Subject: [PATCH 644/878] chore: Enable `unused_async` lint, make some
 functions sync (#23679)

## Which issue does this PR close?

- Closes: N/A

## Rationale for this change

There are a reasonable number of places where we have functions marked
as `async` that don't need to be so. Fix this by enabling the
`unused_async` lint, and fixing up the resulting breakage. There are a
handful of spots that need an `expect(clippy::unused_async)` -- mostly
mocks of `async` methods and example code.

## What changes are included in this PR?

* Enable `unused_async` lint
* Remove unnecessary `async` annotations in a bunch of places
* Add `expect(clippy::unused_async)` where necessary


## Are these changes tested?

Yes, covered by existing tests (no behavioral change expected).

## Are there any user-facing changes?

Yes: this PR updates a few public APIs:

  - `datafusion_cli::command::OutputFormat::execute`
  - `datafusion::test_util::parquet::TestParquetFile::create_scan`
-
`datafusion_datasource_csv::file_format::CsvFormat::read_to_delimited_chunks_from_stream`
  - `datafusion_substrait::serializer::deserialize_bytes`

Migration is mostly straightforward (e.g., removing `await` from calling
code).

+### Unused `async` removed from several public functions
+
+Public functions that were declared `async` but never awaited anything are now
+synchronous:
+
+- `CsvFormat::read_to_delimited_chunks_from_stream` (in
+  `datafusion_datasource_csv`, re-exported as
+  `datafusion::datasource::file_format::csv::CsvFormat`)
+- `datafusion_substrait::serializer::deserialize_bytes`, which now also borrows
+  its input as `&[u8]` instead of taking an owned `Vec<u8>`
+- `datafusion::test_util::parquet::TestParquetFile::create_scan`
+
+**Migration guide:**
+
+Remove `.await` from call sites; the compiler flags each one, since `.await`
+on a non-future value does not compile:
+
+```rust,ignore
+// Before
+let stream = csv_format
+    .read_to_delimited_chunks_from_stream(input)
+    .await;
+let plan = deserialize_bytes(proto_bytes).await?;
+
+// After
+let stream = csv_format.read_to_delimited_chunks_from_stream(input);
+let plan = deserialize_bytes(&proto_bytes)?;
+```

<ul>
<li>
<p>Bump Express to v5. See the <a

</li>
<li>
<p>Convert the source to native ES modules. The package keeps
<code>&quot;type&quot;: &quot;module&quot;</code> and now exposes both
an ESM and a CommonJS build via the <code>exports</code> field: ESM
consumers import the native <code>lib/</code>, while CommonJS consumers
<code>require()</code> a transpiled <code>dist/</code> build, allowing
the package to be consumed from both ESM and CommonJS without relying on
<code>require(ESM)</code> for CommonJS consumers. (by <a

<a
href="https://redirect.github.com/webpack/webpack-dev-server/issues/5674">#5674</a>)</p>
</li>
<li>
<p>Remove CLI flags. Use the <code>serve</code> command from

</li>
</ul>
<h3>Minor Changes</h3>
<ul>
<li>
<p>Add plugin support. <code>webpack-dev-server</code> can now be used
as a webpack plugin, integrating with the compiler lifecycle without
explicitly passing a compiler, preventing multiple server starts on
recompilation, ensuring clean shutdown, and supporting
<code>MultiCompiler</code> setups with multiple independent plugin
servers. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Enable the compression middleware for HTTP/2 connections. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Remove the <code>colorette</code> dependency in favor of native ANSI
styling. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Update <code>chokidar</code> to v5 and extend
<code>watchFiles.options.ignored</code> to support glob string patterns
via <code>tinyglobby</code>. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Use <code>compiler.platform</code> to determine the target
environment instead of inspecting the resolved <code>target</code>
string. Universal targets (<code>&quot;universal&quot;</code> or
<code>[&quot;web&quot;, &quot;node&quot;]</code>, where
<code>compiler.platform.universal</code> is <code>true</code> since
webpack <code>5.108.0</code>) are treated as web targets so the client
runtime is injected. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Use the WHATWG <code>URL</code> API instead of the deprecated
<code>url.parse</code>. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
</ul>
<h3>Patch Changes</h3>
<ul>
<li>
<p>Bump production dependencies, notably <code>open</code> to v11 and
<code>p-retry</code> to v8. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Reject cross-site requests to the internal <code>open-editor</code>
and <code>invalidate</code> endpoints. They performed state-changing
actions (opening a file in the editor, forcing a recompilation) on any
GET request, so a page the developer visited could trigger them. They
now require a same-origin request, validated via
<code>Sec-Fetch-Site</code> with an
<code>Origin</code>/<code>Host</code> fallback. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5691">#5691</a>)</p>
</li>
<li>
<p>Treat loopback aliases (<code>127.0.0.1</code>, <code>::1</code>,
<code>localhost</code>) as equivalent in <code>isSameOrigin</code> so
the WebSocket client does not reject valid same-origin connections. (by
<a href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a>
in <a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Migrate the test suite from Jest to <code>node:test</code> and set up
the jsdom environment. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>

href="https://github.com/webpack/webpack-dev-middleware/releases/tag/v8.0.0">webpack-dev-middleware
v8 release notes</a> for details. (by <a

</li>
</ul>
<h3>Minor Changes</h3>
<ul>
<li>
<p>Add plugin support. <code>webpack-dev-server</code> can now be used
as a webpack plugin, integrating with the compiler lifecycle without
explicitly passing a compiler, preventing multiple server starts on
recompilation, ensuring clean shutdown, and supporting
<code>MultiCompiler</code> setups with multiple independent plugin
servers. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Enable the compression middleware for HTTP/2 connections. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Remove the <code>colorette</code> dependency in favor of native ANSI
styling. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Update <code>chokidar</code> to v5 and extend
<code>watchFiles.options.ignored</code> to support glob string patterns
via <code>tinyglobby</code>. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Use <code>compiler.platform</code> to determine the target
environment instead of inspecting the resolved <code>target</code>
string. Universal targets (<code>&quot;universal&quot;</code> or
<code>[&quot;web&quot;, &quot;node&quot;]</code>, where
<code>compiler.platform.universal</code> is <code>true</code> since
webpack <code>5.108.0</code>) are treated as web targets so the client
runtime is injected. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Use the WHATWG <code>URL</code> API instead of the deprecated
<code>url.parse</code>. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
</ul>
<h3>Patch Changes</h3>
<ul>
<li>
<p>Bump production dependencies, notably <code>open</code> to v11 and
<code>p-retry</code> to v8. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Reject cross-site requests to the internal <code>open-editor</code>
and <code>invalidate</code> endpoints. They performed state-changing
actions (opening a file in the editor, forcing a recompilation) on any
GET request, so a page the developer visited could trigger them. They
now require a same-origin request, validated via
<code>Sec-Fetch-Site</code> with an
<code>Origin</code>/<code>Host</code> fallback. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5691">#5691</a>)</p>
</li>
<li>
<p>Treat loopback aliases (<code>127.0.0.1</code>, <code>::1</code>,
<code>localhost</code>) as equivalent in <code>isSameOrigin</code> so
the WebSocket client does not reject valid same-origin connections. (by
<a href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a>
in <a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>
</li>
<li>
<p>Migrate the test suite from Jest to <code>node:test</code> and set up
the jsdom environment. (by <a
href="https://github.com/bjohansebas"><code>@​bjohansebas</code></a> in
<a
href="https://redirect.github.com/webpack/webpack-dev-server/pull/5674">#5674</a>)</p>

Subject: [PATCH 646/878] refactor(proto): migrate HashJoinExec serde (#23853)

## Which issue does this PR close?

 - Closes #23507.

 ## Rationale for this change

Part of epic #23494. Moves `HashJoinExec` protobuf serialization from
central dispatch.

 ## What changes are included in this PR?

Add protobuf serialization and deserialization to the `HashJoinExec`
physical plan implementation and deprecate the corresponding central
proto methods. The wire format remains unchanged.

 ## Are these changes tested?

 Yes, existing HashJoin round-trip tests cover this plan.

 ## Are there any user-facing changes?

 Existing methods are deprecated with no immediate API change.

Subject: [PATCH 647/878] refactor(proto): migrate AsyncFuncExec to
 self-serializing proto (#23825)

Closes #23514. Part of #23494.

Migrate `AsyncFuncExec` proto encode/decode into the plan itself via
`try_to_proto` / `try_from_proto`, removing its central-arm handling in
`physical_plan/mod.rs`.

## Rationale

`datafusion-proto` currently downcasts `AsyncFuncExec` in the central
encode match and rebuilds it inline on decode. #23495 introduced
self-serializing hooks so each plan owns its own wire format. This moves
`AsyncFuncExec` onto that pattern.

## Changes

- Added `try_to_proto` / `AsyncFuncExec::try_from_proto`, wired into the
decode dispatch
- Removed the central encode downcast branch
- Old helper methods kept as `#[deprecated]` stubs, per existing
convention
- Wire format unchanged

## Testing

Existing `roundtrip_async_func_exec` integration test now exercises the
new hooks (old path deleted, so it's the only path left). `cargo fmt` +
`cargo clippy --all-targets --features proto -- -D warnings` clean.

## User-facing changes

No

Subject: [PATCH 648/878] refactor(proto): migrate window serde (#23780)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23513.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Window plans still relied on centralized protobuf dispatch, keeping
serialization separate from the execution plans that own their state.
Both window executors share one protobuf variant. Decoding must inspect
`input_order_mode` before selecting the concrete plan.

Add plan-local encoders for both executors and a decoder for the shared
node. Keep the legacy helpers as deprecated delegates while preserving
window frames and UDF payloads on the existing wire format.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Yes
## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 649/878] Migrate ExplainExec and AnalyzeExec protobuf serde
 (#23742)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23511.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Physical plan protobuf serialization is being moved from the central
dispatch module into each `ExecutionPlan` implementation. Co-locating
this logic with the corresponding execution plan makes the serialization
code easier to maintain and incrementally reduces the central downcast
chain.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
- Implement plan-local protobuf serialization and deserialization for
  `ExplainExec`.
- Implement plan-local protobuf serialization and deserialization for
  `AnalyzeExec`.
- Remove both plans from the live central serialization dispatch.
- Retain the deprecated compatibility methods as delegates to the new
  implementations.
- Preserve the existing protobuf wire format.
- Strengthen roundtrip tests to cover all stored fields, including every
  `StringifiedPlan` variant, metric categories, and explain formats.

Each execution plan migration is kept in a separate commit.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes. The following checks pass:

- `cargo fmt --all`
- `cargo clippy --all-targets --all-features -- -D warnings`
- Full extended workspace test suite
- `cargo test -p datafusion-proto --test proto_integration`

The proto integration suite passes all 209 tests after rebasing onto the
latest `main`.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No. This is an internal refactor and does not change the protobuf wire
format or user-facing behavior.

Subject: [PATCH 650/878] refactor(proto): migrate aggregate exec serde
 (#23779)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23512.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Aggregate protobuf conversion lived in the central proto crate, which
prevented AggregateExec from owning its function-codec serialization.

Move encoding and decoding into AggregateExec and keep the deprecated
helpers as delegates so existing callers retain wire-compatible
behavior.


## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 651/878] refactor(unparser): centralize aggregate-scope
 rendering in the SQL unparser (#23789)

## Which issue does this PR close?

- Closes #23668.

## Rationale for this change

- When printing a GROUP BY query, the unparser sometimes wraps the
aggregate's input in an inner subquery (`... FROM (SELECT ...)`).
- Table aliases like `cs` only exist inside that subquery. Any clause
outside it (SELECT, GROUP BY, HAVING, QUALIFY, ORDER BY) must use the
subquery's output columns, not the aliases, so the unparser drops the
alias.
- Each clause does that dropping on its own, so it is easy to miss one.
- ORDER BY on an aggregate that is not in the SELECT list was missed: it
printed `ORDER BY round(sum("cs"."total_revenue"), 2)`, while the SELECT
list in the same query correctly printed `sum("total_revenue")`.
- DataFusion reads that SQL back fine, but stricter databases reject it
because `cs` is out of scope there.


## What changes are included in this PR?

I moved the rule into one helper, `UnparserAggScope`, that checks once
per aggregate whether the input is an inner subquery and then prepares
expressions for each clause. SELECT, GROUP BY, HAVING, QUALIFY, and both
ORDER BY paths now go through it, which fixes the ORDER BY case. The
window-over-aggregate path is left as-is with a comment: it is only
reachable from hand-built plans, since a window in SQL always sits
inside a SELECT that already drops the alias. Only ORDER BY output
changes; every already-correct case stays the same.


## Are these changes tested?

Yes. New tests in `datafusion/core/tests/sql/unparser.rs` cover the
inner-subquery shape for a window sorting by an aggregate, ORDER BY on
an unselected aggregate (the fixed case), and a top-level ORDER BY (the
second sort path). Existing unparser tests and the TPC-H/Clickbench
roundtrips still pass.

## Are there any user-facing changes?

ORDER BY over an aggregate is now printed without an out-of-scope table
qualifier, so the generated SQL is valid for stricter databases. No API
changes.

Subject: [PATCH 652/878] Add FixedSizeList support for recursive struct schema
 adaptation (#22980)

## Which issue does this PR close?

* Part of #20835

## Rationale for this change

`FixedSizeList` containing `Struct` values was not handled by the
existing recursive nested adaptation logic used for schema evolution. As
a result, planner-time compatibility checks, nested cast detection, and
runtime casting did not support additive struct evolution within
`FixedSizeList` containers.

This change adds `FixedSizeList` support and verifies planner/runtime
parity so that planning allows exactly the cases runtime can adapt while
continuing to reject incompatible schema changes.

## What changes are included in this PR?

* Extend `cast_column` to support recursive casting of `FixedSizeList`
values when source and target list sizes match.
* Add `FixedSizeList` handling to:

  * `requires_nested_struct_cast`
  * `validate_data_type_compatibility`
* Implement recursive casting of nested `Struct` values contained in
`FixedSizeList`.
* Preserve planner/runtime parity by validating child type compatibility
before runtime fallback logic is applied.
* Add handling for null-parent `FixedSizeList` entries by masking hidden
child values before retrying casts, avoiding failures caused by
semantically inaccessible child data.
* Refactor list and list-view casting helpers to use Arrow `AsArray`
accessors.

## Are these changes tested?

Yes.

The following tests were added:

* `test_cast_fixed_size_list_struct`
* `test_validate_fixed_size_list_struct_compatibility`
*
`test_validate_fixed_size_list_struct_missing_non_nullable_field_rejected`
* `test_validate_fixed_size_list_struct_size_mismatch_rejected`
* `test_cast_fixed_size_list_struct_all_null`
*
`test_fixed_size_list_struct_planner_runtime_parity_on_incompatible_type`
*
`test_cast_fixed_size_list_struct_missing_non_nullable_field_runtime_rejected`
*
`test_cast_fixed_size_list_struct_ignores_hidden_child_values_for_null_parent`

Existing coverage in `test_requires_nested_struct_cast` was also
extended to include `FixedSizeList` cases.

These tests cover:

* Additive nullable nested-field evolution
* All-null and partially null list cases
* Incompatible nested type changes
* Non-nullable field addition rejection
* Planner/runtime parity validation

## Are there any user-facing changes?

No user-facing changes. This is an internal enhancement to nested schema
adaptation and casting behavior for `FixedSizeList<Struct>` types.

Subject: [PATCH 653/878] refactor: share hex encoding across
 datafusion-common, functions, and spark (#23766)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Hex encoding was implemented six times across the workspace, at two
different levels of optimization.

Three copies used a fast byte-pair lookup table:

- `datafusion/spark/src/function/math/hex.rs`
- `datafusion/functions/src/string/to_hex.rs`
- `datafusion/functions/src/encoding/inner.rs` (via the `hex` crate)

The other three used a slower nibble-at-a-time loop pushing one
character at a time:

- `datafusion/functions/src/crypto/md5.rs`
- `datafusion/spark/src/function/hash/sha1.rs`
- `datafusion/spark/src/function/hash/sha2.rs`

Beyond the duplication, this split meant the digest functions were
paying for a slower encoder
than the one already sitting elsewhere in the tree. Consolidating on a
single implementation
removes the duplication and moves `md5`, `sha1`, and `sha2` onto the
fast path.

## What changes are included in this PR?

A new `datafusion_common::utils::hex` module holds the only hex encoder
in the workspace:

```rust
pub enum HexCase { Lower, Upper }

pub fn encode_bytes_into(bytes: &[u8], case: HexCase, out: &mut Vec<u8>);
pub fn encode_bytes(bytes: &[u8], case: HexCase) -> String;
pub fn encode_bytes_to_slice(bytes: &[u8], case: HexCase, out: &mut [u8]);
pub fn encode_u64(v: u64, case: HexCase, buf: &mut [u8; 16]) -> &[u8];
```

Four entry points rather than one because the call sites have genuinely
different output needs,
and forcing them through a single shape would cost an allocation
somewhere: `to_hex` writes
straight into a `StringArray` values buffer, Spark's `hex` appends to a
reused scratch `Vec`,
`encode` writes into a pre-sized slice, and the digest functions want an
owned `String`.

Migrated call sites, all producing bit-identical output:

| File | Change |
| --- | --- |
| `functions/src/string/to_hex.rs` | local table and two write helpers
deleted; eight trait impls collapsed to two macros |
| `spark/src/function/math/hex.rs` | two nibble tables, two lookup
tables, `build_hex_lookup` and `hex_int64` deleted |
| `functions/src/crypto/md5.rs` | local table and `hex_encode` deleted |
| `spark/src/function/hash/sha1.rs` | local table and inline nibble loop
deleted |
| `spark/src/function/hash/sha2.rs` | local table and `hex_encode`
deleted; eight call sites migrated |
| `functions/src/encoding/inner.rs` | both encode sites moved off the
`hex` crate |

Deliberately left alone:

- `hex::decode` / `hex::decode_to_slice` in `encoding/inner.rs`, and
Spark's `unhex`. The decode
direction has different semantics — Spark's `unhex` left-pads odd-length
input, the `hex` crate
does not — so unifying it is a separate question. The `hex` dependency
stays for those.
- `ScalarValue`'s binary `Display` impl in `common/src/scalar/mod.rs`,
which writes to a
  `fmt::Formatter` rather than a byte buffer, and is a cold path.

Three details worth a reviewer's attention:

- The two ancestors of `encode_u64` disagreed on zero: `to_hex` wrote
`'0'` into the caller's
buffer, Spark's `hex_int64` returned a `'static` `b"0"` that never
touched it. The shared version
always writes into the buffer and returns a subslice of it, so the
lifetime is uniform. Both
  callers still produce `"0"`.
- Spark's `hex_encode_bytes` guards large binary input with
`checked_mul(2)` + `try_reserve`,
returning a `DataFusionError` rather than aborting on allocation
failure. That guard stays at the
call site; `encode_bytes_into` performs no reservation of its own, so
behaviour is unchanged.
- The encoders are `#[inline(always)]`, not `#[inline]`. They are called
once per row from two
other crates, and plain `#[inline]` left them out-of-line across the
crate boundary. Measured
cost of that: +3% on Spark's byte paths and up to +18% on `to_hex`'s i32
path, i.e. the
refactor was a net regression on those benchmarks until the attribute
changed.

## Are these changes tested?

Every migrated function keeps its existing unit and sqllogictest
coverage, which is what pins
bit-identical output — in particular `spark/hash/sha1.slt` and
`sha2.slt` assert concrete digest
strings for all four SHA-2 bit lengths across both the scalar and array
paths, and `expr.slt`
covers `to_hex` and `md5`.

New unit tests in `common/src/utils/hex.rs` cover zero, `u64::MAX`,
single-nibble values, the
odd/even digit-count boundary, two's complement of negative input, empty
input, all 256 byte
values in both cases, appending into a non-empty buffer, and that a
reused scratch buffer never
leaks stale digits between calls. Tests cross-check against
`format!("{:x}")` rather than
restating the implementation.

Two Spark tests changed. `test_hex_int64` now drives `hex_encode_int64`
instead of the deleted
private `hex_int64`, keeping all ten cases including `i64::MIN`, `-1`,
and the uppercase
expectations. `test_hex_lookup_table_covers_all_bytes` was deleted — it
only cross-checked the raw
lookup tables, and `encode_bytes_covers_every_byte_value` now does that
exhaustively through the
public API. A test was added for Spark's lowercase byte path, which
previously had no coverage.

### Benchmarks

Criterion, `apache/main` @ `eef101769` as baseline. Median of the
reported change interval.

`datafusion/functions/benches/to_hex.rs`:

| Benchmark | 1024 | 4096 | 8192 |
| --- | --- | --- | --- |
| `i32_random` | −13.8% | −12.8% | −10.2% |
| `i64_random` | −8.8% | −9.5% | −8.1% |
| `i64_large_values` | −9.9% | −9.8% | −7.9% |

`scalar_i32` −2.3%, `scalar_i64` −1.8%.

`datafusion/spark/benches/sha2.rs`:

| Benchmark | 1024 | 4096 | 8192 |
| --- | --- | --- | --- |
| `array_binary_256` | −20.7% | −18.2% | −19.1% |
| `array_scalar_binary_256` | −14.6% | −13.2% | −13.1% |

`scalar/size=1` −3.3%.

`datafusion/spark/benches/hex.rs`:

| Benchmark | 1024 | 4096 | 8192 |
| --- | --- | --- | --- |
| `hex_int64` | −2.9% | −3.6% | −3.5% |
| `hex_int64_dict` | −3.2% | −1.5% | −0.2% |
| `hex_utf8` | −0.2% | −0.3% | +0.7% |
| `hex_binary` | −0.4% | −0.6% | −0.3% |

The `hex_utf8` and `hex_binary` paths already used the byte-pair table
before this PR, so they are
expected to be flat; they are.

`datafusion/functions/benches/crypto.rs`: `md5_array` −4.0%,
`md5_scalar` −3.7%. The `sha224` /
`sha256` / `sha384` / `sha512` cases in that file range from −0.1% to
+2.2%, but they exercise
`crypto/basic.rs`, which this PR does not modify and which contains no
hex encoding — those numbers
are run-to-run variance, not an effect of this change.

No number is quoted for Spark `sha1`: it has no benchmark, and its
change is the same substitution
applied to `md5` and `sha2`.

## Are there any user-facing changes?

No behaviour change — all migrated functions produce byte-identical
output.

`datafusion_common::utils::hex` is new public API on
`datafusion-common`.

Subject: [PATCH 654/878] test: cover `array_agg(DISTINCT)` on dictionaries and
 bounded `retract_batch` memory (#23873)

## Which issue does this PR close?

- related to https://github.com/apache/datafusion/pull/23716


## Rationale for this change

It adds test coverage for two gaps found while reviewing
https://github.com/apache/datafusion/pull/23716.


## What changes are included in this PR?

Tests only, no functional change.
- Dictionary inputs
- memory usage on retract (make sure memory is released)

Note I moved `array_agg` cases out `aggregate.slt` as it is already more
than 9k lines long

## Are these changes tested?
They are only tests

## Are there any user-facing changes?

No. Tests only, no public API changes.

Subject: [PATCH 655/878] perf: avoid per-row String allocation in Spark bin
 and char (#23881)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Two Spark functions allocated a `String` per row purely to render a
small,
bounded amount of text:

- `bin` called `format!("{value:b}")` for every row.
- `char` called `ch.to_string()` for every row — a heap allocation for a
single
  character.

In both cases the output has a known upper bound (64 binary digits for
an `i64`,
4 bytes for a UTF-8 character), so the rendering fits in a stack buffer
and the
result can be appended straight to a pre-sized builder.

## What changes are included in this PR?

`math/bin.rs`:

- `spark_bin` now writes digits right-aligned into a caller-supplied
`[u8; 64]`
and returns a `&str` borrowed from it, instead of returning an owned
`String`.
- The `collect::<StringArray>()` becomes an explicit loop over a
  `StringBuilder::with_capacity`, sized at 8 digits per row.
- Negative values still render as their two's-complement bit pattern,
matching
`{:b}`. The digit loop is a `loop`, not a `while`, so zero renders as
`"0"`
  rather than the empty string.

`string/char.rs`:

- `ch.to_string()` becomes `ch.encode_utf8(&mut encoded)` against a
`[u8; 4]`
  hoisted out of the loop.

Output is unchanged in both cases.

## Are these changes tested?

Existing coverage pins the behaviour. `spark/math/bin.slt` asserts
concrete
output for the cases the rewrite had to get right: zero, negative
values,
`i64::MIN` (`-9223372036854775808`), `i64::MAX`, and `-2147483648` /
`-32768` widened from narrower integer types. `spark/string/char.slt`
covers
the negative-input empty string, the null path, and characters on both
sides of
the ASCII boundary (`char(256)` and above wrap via `% 256`).

All 119 `spark/math` and `spark/string` sqllogictest files pass, along
with the
258 `datafusion-spark` unit tests.

The `bin` benchmark used below, `datafusion/spark/benches/bin.rs`, is
added
separately in #23882 so the baseline can be measured on `main` before
this
change lands. It covers 1024 and 8192 rows with 20% nulls over two value
distributions: small values that render to a handful of digits, and
full-range
values that render to the maximum 64. `char` already had
`datafusion/spark/benches/char.rs` on `main`, so no benchmark change is
needed
for it.

### Benchmarks

Criterion, `apache/main` @ `f1ab86dad` as baseline. Median of the
reported
change interval.

| Benchmark | 1024 | 8192 |
| --- | --- | --- |
| `bin/small` | −75.7% | −73.7% |
| `bin/wide` | −47.8% | −49.8% |

`char` (1024 rows): −76.1%.

## Are there any user-facing changes?

No. Both functions produce byte-identical output; this is purely an
allocation
change.

Subject: [PATCH 657/878] fix: don't infer join predicates for null-aware joins
 in push_down_filter (#23901)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23900.

## Rationale for this change

`push_down_filter` infers equi-key predicates across a join's ON keys
and pushes them to the opposite side. For a null-aware join (the
`LeftAnti` join produced by `NOT IN` with a nullable subquery), an outer
predicate on the left key like `outer.id > 5` is rewritten to `sub.id >
5` and pushed onto the subquery input. Since the inferred predicate must
be null-rejecting to be pushed, this drops the subquery's NULL rows and
breaks the three-valued `NOT IN` semantics — a NULL in the subquery key
must reach the join so the result is empty.

Same class of bug as #23848, in a different rule.

## What changes are included in this PR?

- Skip predicate inference in `infer_join_predicates` when
`join.null_aware` is set (mirrors the #23848 guard on
`FilterNullJoinKeys`).
- A `push_down_filter` unit test asserting no predicate is inferred onto
the subquery side of a null-aware `LeftAnti` join.
- SLT coverage for the failing query, plus a `prefer_hash_join = false`
/ multi-partition variant.

## Are these changes tested?

Yes — new unit test (verified it fails without the guard) and SLT cases.
The full optimizer lib suite passes.

## Are there any user-facing changes?

No, aside from the correctness fix.

Subject: [PATCH 658/878] IN LIST: add branchless filter for small primitive
 lists (#23014)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #19241.
- Stacked on [#23311](https://github.com/apache/datafusion/pull/23311).
- Next in stack: #23015.
- Extracted from #19390.

## Rationale for this change

For very small `IN` lists, building or probing a hash table can be more
work than just comparing the input value with each constant.

For example, for `x IN (10, 20, 30)`, the fast path can behave like:

```text
x == 10 OR x == 20 OR x == 30
```

Because the list is tiny, those comparisons are cheap. The
implementation stores the constants in a fixed-size array and checks
them with a compact comparison chain.

“Branchless” here means the comparisons are combined without stopping at
the first match. That can be faster for these small fixed-width lists
because the CPU gets a predictable sequence of simple operations instead
of hash-table setup and probe logic.

For primitive values that are not already plain unsigned integers, this
PR keeps the logical Arrow type explicit and uses a matching same-width
comparison representation only inside the branchless filter. For
example, `Float16` uses `UInt16` storage, `Float32` uses `UInt32`
storage, and `TimestampNanosecond` uses `UInt64` storage. `Decimal128`
and `IntervalMonthDayNano` use their own 16-byte native representation.
This preserves bit-pattern equality while relying on Arrow's native
primitive compatibility rules: timestamp timezone metadata and
Decimal128 precision/scale metadata may differ, while incompatible
primitive representations remain rejected.

## What changes are included in this PR?

- Adds a const-generic `BranchlessFilter` for small primitive `IN`
lists.
- Adds thresholds for when this path is used:
  - up to 16 values for 1-byte types
  - up to 8 values for 2-byte types
  - up to 32 values for 4-byte types
  - up to 16 values for 8-byte types
  - up to 4 values for 16-byte types
- Keeps dispatch concrete and explicit in `strategy.rs`.
- Maps each optimized logical type to the comparison representation used
by the branchless filter:
  - `Int8` -> `UInt8`
  - `Int16`, `Float16` -> `UInt16`
  - `Int32`, `Float32`, `Date32`, `Time32` -> `UInt32`
- `Int64`, `Float64`, `Date64`, `Time64`, `Timestamp`, `Duration` ->
`UInt64`
- `Decimal128`, `IntervalMonthDayNano` -> their native 16-byte
representation
- Leaves larger 1-byte and 2-byte lists on the existing bitmap filters.
- Leaves larger 4-byte and 8-byte lists on the existing hash/generic
paths.
- Leaves wider primitive types such as `Decimal256` and unsupported
complex types on the generic path.
- Keeps the same `IN` / `NOT IN` null behavior as the rest of the stack.
- Adds focused coverage for branchless null handling, signed boundary
values, slices, Float16/Float32/Float64 bit patterns, compatible
timestamp/Decimal128 metadata, incompatible timestamp units,
IntervalMonthDayNano values, and same-width wrong-type probe rejection.

## Are these changes tested?

Yes.

- `cargo test -p datafusion-physical-expr expressions::in_list --lib`
- `cargo test -p datafusion-physical-expr --bench in_list_strategy
--no-run`
- `cargo clippy --all-targets --all-features -- -D warnings`

## Are there any user-facing changes?

No. This is an internal performance optimization only.

## Local benchmark snapshot

Built and run with `release-nonlto`, filtered to the relevant small
primitive-list rows:

```bash
cargo bench -p datafusion-physical-expr --profile release-nonlto --bench in_list_strategy -- <filter> --save-baseline <baseline>
```

Filters used: `narrow_integer`, `primitive/i32/small_list`,
`primitive/i64/small_list`, `f32/small_list`, `timestamp_ns/small_list`,
and `interval_month_day_nano/small_list`.

Method: directly compared Criterion's raw sample minima (`min(time /
iterations)`) from `sample.json`. Lower is better; changes within +/-5%
are treated as noise.

Compared baselines:
[#23311](https://github.com/apache/datafusion/pull/23311) ->
[#23014](https://github.com/apache/datafusion/pull/23014)

Relevant scope: small primitive-list rows.

Summary: 39 relevant rows, 28 faster, 0 slower, 11 within +/-5%.

Subject: [PATCH 659/878] feat: add Spark-compatible hypot function (#23774)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23770
- Part of #15914

## Rationale for this change

Spark provides [`hypot(expr1,
expr2)`](https://spark.apache.org/docs/latest/api/sql/#hypot), which
returns `sqrt(expr1^2 + expr2^2)` computed without intermediate overflow
or underflow. It was not yet implemented in `datafusion-spark` — only an
auto-generated test stub existed at `spark/math/hypot.slt` with its
query commented out.

## What changes are included in this PR?

- Add `SparkHypot` (implementing `ScalarUDFImpl`) in
`datafusion/spark/src/function/math/hypot.rs`, backed by Rust's
`f64::hypot` — the same overflow-safe algorithm as Java/Spark's
`Math.hypot`.
- Register it in `datafusion/spark/src/function/math/mod.rs`.
- Enable the `hypot.slt` sqllogictest.

The signature is `exact(Float64, Float64) -> Float64`, following the
`datafusion-spark` convention of only accepting types Spark supports.
Computation uses the Arrow `binary` kernel so NULL in either argument
propagates to a NULL result, matching Spark.

## Are these changes tested?

Yes — `datafusion/sqllogictest/test_files/spark/math/hypot.slt` covers:
- scalar Pythagorean triples (`hypot(3, 4)` → 5, `hypot(5, 12)` → 13),
- double inputs,
- NULL propagation when either argument is NULL,
- the array path (including a NULL row),
- overflow-safety: `hypot(3e200, 4e200)` stays finite, whereas a naive
`sqrt(a^2 + b^2)` would overflow to `Infinity`.

## Are there any user-facing changes?

Yes — adds the Spark-compatible `hypot` scalar function to
`datafusion-spark`. No breaking changes to public APIs.

Subject: [PATCH 660/878] chore: adjust `size` accounting for `min_max`
 (#23899)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of #23393 .

   ## Rationale for this change

`SlidingMinAccumulator::size` and `SlidingMaxAccumulator::size` only
reported
the stack size of their `ScalarValue` field plus its heap payload,
ignoring the
memory held by the underlying `MovingMin` / `MovingMax` sliding-window
buffers.
For windowed `MIN`/`MAX` over string or list data, the two per-element
stacks
can hold megabytes of `ScalarValue` payload that the memory pool was
never
  told about, understating accumulator memory usage.

  ## What changes are included in this PR?

- Add a private `heap_size(elem_heap)` method to `MovingMin<T>` and
`MovingMax<T>`
that reports the two stack buffers' capacity in bytes plus each stored
    element's heap payload.
- Factor the shared implementation into a `moving_stacks_heap_size` free
helper
    so the two types stay in sync.
  - Include the buffer bytes in `SlidingMinAccumulator::size` and
    `SlidingMaxAccumulator::size` via the new method.

  ## Are these changes tested?

Yes. Two new unit tests in
`datafusion/functions-aggregate/src/min_max.rs`:

- `moving_min_max_heap_size_i32` — fixed-width `T`, verifies buffer-only
    accounting with and without pushed elements.
- `moving_min_max_heap_size_counts_elems` — `T = String`, verifies each
of the
two slots in a `(T, T)` pair contributes independently to the heap
payload
    (mirroring the two independent `Clone`s made by `push`).

Subject: [PATCH 661/878] Add ObjectStore-backed TempFileFactor / spill 
 example (#23170)

## Which issue does this PR close?

- Related to
https://github.com/apache/datafusion/pull/21882#issuecomment-4793942224.

## Rationale for this change

PR #21882 adds custom spill file support.

Having an example showing how a downstream application can use this new
API will help make sure the API is good enough for our needs

## What changes are included in this PR?

This PR adds a small example showing how users can back spill files with
an `ObjectStore`, using a local object store for a runnable example
while keeping the implementation applicable to remote stores.

## Are these changes tested?

Yes by CI

## Are there any user-facing changes?

Yes. This adds a new example for configuring ObjectStore-backed spill
files.

Subject: [PATCH 662/878] refactor(proto): remove legacy scan field (#23445)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #N/A.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Since DataFusion doesn't typically guartantee wire format compatibility,
I remove the backward compatiblity shim that introduced in PR #23189

FYI:
https://github.com/apache/datafusion/pull/23189#discussion_r3554855165


## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

DataFusion does not guarantee serialized plans across versions. Keeping
`partitioned_by_file_group` therefore leaves a dead schema field and
decoder path after `output_partitioning` became the source of truth.
Reserve the old field number and name to prevent future reuse.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
Yes

Subject: [PATCH 663/878] fix: skip dynamic filter pushdown for null-aware anti
 joins with a nullable build key (#23173)

## Which issue does this close?

- Closes #23126.

## Rationale for this change

`x NOT IN (subquery)` plans to a null-aware `LeftAnti` hash join (build
= outer `x`, probe = subquery). Join dynamic filter pushdown pushes a
bounds + membership filter, built from the build keys, onto the probe
scan. That filter can prune every probe row. A null-aware `LeftAnti`
reads an empty probe as a genuinely-empty subquery, so it emits
build-side NULL rows that should drop: `NULL NOT IN (non-empty)` is
UNKNOWN, not TRUE.

The result is scan-dependent, so it's a silent correctness bug. A
`VALUES` scan ignores the pushed filter and stays correct; a parquet
scan applies it and is wrong.

#23103 (the probe-side NULL drop) is orthogonal; this is the build-side
NULL.

## What changes are included in this PR?

Skip join dynamic filter pushdown for a null-aware anti join when the
build key can be NULL. The build-side NULL emission depends on whether
the probe is truly empty, which the pushed filter can change by emptying
it. A NOT NULL build key has no such NULL, so it keeps the pushdown.

The check is static: a schema-nullable build key disables the pushdown
even when the data contains no NULLs. A runtime alternative (keep the
pushdown and neutralize the filter only when the build actually holds a
NULL key) would restore the optimization for those cases. I'd leave that
as a follow-up.

## Are these changes tested?

Yes. A `push_down_filter_parquet.slt` case reproduces it (build-side
NULL, a non-matching parquet probe) and asserts the single correct row.
Without the change it returns the extra NULL. In addition, unit tests
pin both directions of the guard: a nullable build key rejects the
pushdown and a NOT NULL build key keeps it.

## Are there any user-facing changes?

`NOT IN` over a parquet (or otherwise prunable) scan with a nullable
outer key now returns correct results. Such joins lose the dynamic
filter pushdown.

Subject: [PATCH 664/878] Various `ScalarValue` numeric method fixes &
 refactors (especially decimal) (#23631)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

N/A

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

I noticed there were some subtle errors with how decimals were handled
in scalar values, and also opportunity to remove power calls in favour
of precomputed constant tables. Also filling out some other missing
support.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

I recommend looking at the commits as they are self contained with
detailed messages for each.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

No

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

From: Adam Gutglick <adamgsal@gmail.com>
Date: Sun, 26 Jul 2026 19:48:49 +0100
Subject: [PATCH 665/878] fix: Handle `input_file_name()` pushdown into
 `ParquetSource` with filter pushdown enabled (#23638)

## Which issue does this PR close?

- Closes #23531.

## Rationale for this change

`input_file_name()` is `FileSource` dependent like `file_row_index()`,
and therefore shouldn't be pushed down into a filter.

## What changes are included in this PR?

`PushdownChecker` now handles both UDFs consistently.

If we keep adding this sort of metadata functions, we might want a
better API to detect them, but for now I think this is a reasonable
approach that isn't very invasive.

## Are these changes tested?

Additional SLT test that verifies that both function behave correctly
with pushdown either enabled or disabled.

## Are there any user-facing changes?

None

Subject: [PATCH 666/878] fix: exclude precision-losing integer-to-float
 conversions from CastExpr::check_bigger_cast (#23808) (#23809)

## Which issue does this PR close?

- Closes #23808.

## Rationale for this change
 ref. #23807

`CastExpr::check_bigger_cast` is used to determine whether a cast is a
widening (order-preserving) conversion. Currently, it classifies `Int32
-> Float32`, `UInt32 -> Float32`, `Int64 -> Float64`, and `UInt64 ->
Float64` as widening casts.

However, integer-to-float conversions for 32-bit and 64-bit integers
lose precision when values exceed the mantissa bit limit (24 bits for
`Float32`, 53 bits for `Float64`). For example:
`16_777_216_i32 as f32 == 16_777_217_i32 as f32` (both yield
16777216.0f32).

Because distinct integer inputs can collapse to the same float output,
these casts are not strictly 1-to-1 (injective) and can break suffix
sort key ordering in multi-column ordering analysis (e.g. `[CAST(a AS
Float32), b]`).

## What changes are included in this PR?

- Updated `CastExpr::check_bigger_cast` to exclude precision-losing
integer-to-float conversions (`Int32/UInt32 -> Float32` and
`Int64/UInt64 -> Float64`).
- Added unit test `test_check_bigger_cast_precision_loss` to verify
precision-losing casts return `false` while exact conversions (`Int16 ->
Float32`, `Int32 -> Float64`, etc.) continue to return `true`.

## Are these changes tested?

Yes, new unit test `test_check_bigger_cast_precision_loss` in `cast.rs`.

## Are there any user-facing changes?

No breaking API changes. Internal optimizer behavior fix.

Subject: [PATCH 667/878] chore: simplify SortPreservingMergeStream to be as
 textbook-like as possible (#23702)

## Which issue does this PR close?

N/A

## Rationale for this change

`SortPreservingMergeStream` is a little complex, so add some guiding
comments and make it as textbook-like as possible

## What changes are included in this PR?

Added comments, reorder code

While this was done this also fixed couple of bugs due to how it work:
1. leftover drain was not counted in the `elapsed_compute`
2. `limit(0)` returns 0 rows and not 1

## Are these changes tested?
Existing tests

## Are there any user-facing changes?
Not API ones.

`limit(0)` now returns 0 rows

Subject: [PATCH 668/878] feat: add BuildHasher variants for hash_utils
 (#21820)

## Which issue does this PR close?

- Closes https://github.com/apache/datafusion/issues/21428.

## Rationale for this change

This PR adds `BuildHasher`-based variants for `hash_utils` so callers
can compute row hashes with a caller-provided hash builder instead of
always using DataFusion's default `RandomState`.

The main constraint is performance: `with_hashes` is a hot path,
especially for string, dictionary, and nested array hashing. A previous
version in #21429 caused measurable regressions in the default
`RandomState` path, for example `large_utf8: single, no nulls` regressed
from roughly `26.7us` to `36.3us`, and `large_utf8: multiple, no nulls`
from roughly `112us` to `127us`.

This version keeps the default path performance-oriented by avoiding a
fully generic `BuildHasher` rewrite of the existing hot loops.

## What changes are included in this PR?

This PR adds:

- `with_hashes_with_hasher`
- `create_hashes_with_hasher`
- custom-hasher implementations for primitive, string, binary,
byte-view, dictionary, and nested arrays
- tests covering custom hashers, multi-column hashing, and dictionary
equivalence

The implementation intentionally uses a hybrid design:

- Default `RandomState` leaf hot paths remain specialized.
- Custom `BuildHasher` leaf paths live separately in
`hash_utils/build_hasher.rs`.
- Nested/structural logic is shared through an internal child-hashing
adapter, so struct/list/map/union/run/dictionary behavior does not need
to be broadly duplicated.

The trade-off is that there is still some duplication for
primitive/string/binary leaf loops. That duplication is intentional:
those are the hottest loops, and keeping them separate prevents the
existing `RandomState` path from becoming generic over `BuildHasher` or
being perturbed by the custom-hasher implementation.

## Are these changes tested?

Yes.

Subject: [PATCH 669/878] `ScalarUdfImpl::strictly_order_preserving`: Allow
 expression to report whether they keep the same ordering of the input
 (#23807)

## Which issue does this PR close?

- Closes #23798

Related to:
- #16217

## Rationale for this change

To be able to keep the same sorting order allowing for more
optimizations

Now comet own `cast` implementation can be recognized as not modifying
sort order in the same cases that datafusion cast does.

## What changes are included in this PR?
added `strictly_order_preserving` property to `ExprProperties` + varius
other places
and replaced the hard coded logic for cast (`substitute_cast_ordering`)
about keeping input order with more generic approach that now any
expression can implement and have the same advantage of sort elimination

also marked from_unixtime as keeping ordering to show a case of this
optimization

## Are these changes tested?
yes

## Are there any user-facing changes?
yes, breaking change, added `strictly_order_preserving` property to
`ExprProperties` and to `FFI_ExprProperties`


this property means that given expression `f` and 2 values from the
input column `a` and `b` the following variants are kept:
1. `a.cmp(b) == f(a).cmp(f(b))`
2. nulls maps to nulls

Example of satisfying expression:
`cast(col_a as BIGINT)` where `col_a` is `INT` it is keeping the
properties

Example of not satisfying:

`floor` - floor can not

`array_repeat(my_col, 2)` which might look like at first glance as
keeping the property as well but in fact it does not.

the reason is that `array_repeat(null, 2)` will output list of 2 nulls
which breaks the 2nd property that nulls must be kept as nulls


how to migrate:

Option 1 - keeping the old behavior (safest but least performant)
set `strictly_order_preserving` to false

Option 2 - Using the new optimization that this opens up:
set `strictly_order_preserving` only if the expression keep both
variants

Subject: [PATCH 670/878] FFI: forward ScalarUDF preserves_lex_ordering
 (#23069)

## Which issue does this PR close?

Part of #22330.

## Rationale for this change

`ForeignScalarUDF` inherits the default `preserves_lex_ordering`, so
producer overrides are lost across the FFI boundary.

## What changes are included in this PR?

- Forward `preserves_lex_ordering` through `FFI_ScalarUDF`.
- Reuse the existing placement UDF for unit and dynamic-library
coverage.

## Are these changes tested?

- `cargo test -p datafusion-ffi --features integration-tests`
- `cargo clippy --all-targets --all-features -- -D warnings`

## Are there any user-facing changes?

The FFI ABI changes. Foreign libraries must rebuild against the new
DataFusion version.

Subject: [PATCH 671/878] perf(functions-aggregate): optimize sliding window
 MIN/MAX using monotonic deques (#23826) (#23827)

## Which issue does this PR close?

- Closes #23826

### What changes are included in this PR?

This PR optimizes sliding window `MIN`/`MAX` aggregate functions using a
**Sequence-Numbered Monotonic Deque** instead of a Two-Stack Queue.

**Revised Design:**
- We store `(sequence_number, value)` pairs in a single `VecDeque`, kept
in strictly monotonic order.
- **`push(val)`**: Evicts dominated elements from the back, then pushes
the new value with the current `push_seq` and increments `push_seq`.
- **`pop()`**: Increments `pop_seq`. If the front elements sequence
number equals the old `pop_seq`, it is expired and popped.
- **Benefits**: No secondary FIFO queue (lower memory) and no `clone()`
overhead.

### Are these changes tested?
Yes, existing tests pass. Added tests for empty-window `pop()` and
duplicate-heavy scenarios.

### Are there any user-facing changes?
**API Change**: `MovingMin` and `MovingMax` were changed to `pub(crate)`
visibility, and their `pop()` methods now return `()` instead of
returning a value.
Performance is significantly improved (2x-3.5x throughput).

+### `MovingMin` and `MovingMax` changed to `pub(crate)`
+
+`MovingMin` and `MovingMax` in `datafusion_functions_aggregate::min_max` have been changed from `pub` to `pub(crate)` visibility as they are internal helper data structures for DataFusion's sliding window aggregators.
+
+**Who is affected:**
+
+- Code that directly imported `MovingMin` or `MovingMax` from `datafusion_functions_aggregate`. Standard SQL window functions (`MIN(...) OVER (...)` / `MAX(...) OVER (...)`) are unaffected.
+
+See [PR #23827](https://github.com/apache/datafusion/pull/23827) for details.

Subject: [PATCH 673/878] fix: eliminate group by constant empty input (#22132)

## Which issue does this PR close?

- Closes #11748

## Rationale for this change

`EliminateGroupByConstant` removes GROUP BY expressions that are
constants. If all of the GROUP BY expressions are constants, eliminating
all of them results in converting a grouped aggregate into an ungrouped
(global) aggregate. This changes the semantics of the query: a grouped
aggregate query on an empty input returns zero rows, whereas an
ungrouped aggregate query produces a single row.

## What changes are included in this PR?

`EliminateGroupByConstant` now declines to eliminate constant GROUP BY
expressions, if doing so would result in removing all of the grouping
expressions.

## Are these changes tested?

Yes. Sqllogictest reproducer for the original issue, updated unit test
and optimizer SLT expectations.

## Are there any user-facing changes?

Queries with all-constant GROUP BY may now return fewer (correct) rows.

Subject: [PATCH 674/878] fix: sliding window `min()` returns wrong value for
 all-NULL windows (#23874)

## Which issue does this PR close?

- Closes #23872

## Rationale for this change

`SlidingMinAccumulator::update_batch` skipped NULL values. This meant
that if all the non-NULL values in a window frame were retracted, the
window frame would not be empty but the `MovingMin` data structure by
the `SlidingMinAccumulator` would not contain any values. This resulted
in incorrectly returning a stale non-NULL value for a sliding `min()`
over a window frame consisting of only NULL values.

Along the way, optimize the min and max sliding window accumulators to
make them both more efficient and more symmetric with one another. In
the original coding, `SlidingMaxAccumulator` included NULL values but
`SlidingMinAccumulator` omitted them, in part because omitting NULLs
made the original `retract_batch` implementation more expensive. This PR
optimizes `retract_batch`, so we can now use the same scheme for both
the min and max sliding accumulators:

* Omit NULLs on `update_batch` (this improves on the prior behavior of
`max`)
* Efficiently account for NULLs in `retract_batch` (this improves on the
prior behavior of `min`)
* Ensure correct results for all-NULL window frames (this fixes the
prior bug in `min`).

## What changes are included in this PR?

* Fix bug in `min()` over all-NULL window frames
* Optimize `SlidingMinAccumulator::retract_batch` (avoid materializing
values just to count NULLs)
* Optimize `SlidingMinAccumulator::update_batch` (omit NULLs), also
improving symmetry with `min`
* Optimize both accumulators to stop caching the current `min` / `max`;
this saves a few clones, but perhaps more importantly it is simpler and
avoids the risk of inconsistency between the cached value and the
underlying `MovingMin` / `MovingMax` data structure

## Are these changes tested?

Yes, new tests added.

## Are there any user-facing changes?

No, aside from the bug fix.

Subject: [PATCH 676/878] fix: correct percentile_cont(DISTINCT) accumulation
 and sliding-window retract (#23913)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23912.

## Rationale for this change

`DistinctPercentileContAccumulator` reused the shared set-based
`GenericDistinctBuffer`, which doesn't fit it: (1) the buffer asserts a
single input column but `percentile_cont` passes two (value +
percentile), so every `percentile_cont(DISTINCT ...)` panicked; (2) the
buffer is a plain `HashSet` with no multiplicity, so sliding-window
`retract_batch` dropped a value while duplicates were still in the
frame.

## What changes are included in this PR?

- Replace the shared buffer in this accumulator with a per-accumulator
`HashMap<Hashable, usize>` count map: `update_batch` reads only the
value column and increments; `retract_batch` decrements and removes a
key only at zero; `state`/`merge_batch` keep the same List state shape.
Other `GenericDistinctBuffer` users are untouched.
- Regression tests in `aggregate.slt` for the plain distinct query and
the sliding-window duplicate-retract case.

## Are these changes tested?

Yes — new regression tests; the full `aggregate.slt` suite passes.

## Are there any user-facing changes?

`percentile_cont(DISTINCT ...)` now works instead of panicking, and
returns correct results in sliding windows.

Subject: [PATCH 677/878] fix: support parentheses for negative decimal
 formatting (#23718)

## Which issue does this PR close?

- Closes #23717.

## Rationale for this change

Spark and Java format negative numeric values with parentheses when the
`(` flag is present. The decimal formatting path always emitted a minus
sign because it ignored `negative_in_parentheses`, while the
floating-point path already handled the flag. This made `format_string`
inconsistent across numeric input types.

## What changes are included in this PR?

- Add a closing suffix when a negative decimal uses parentheses
formatting.
- Include the suffix when calculating width, left alignment, and zero
padding.
- Add regression coverage for grouped negative decimals with and without
an explicit width.

## Are these changes tested?

Yes. The following checks pass locally:

- `cargo fmt --all -- --check`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `cargo test -p datafusion-spark --lib`
- The full workspace test command from the contributor guide with
`avro,json,backtrace,extended_tests,recursive_protection,parquet_encryption`
enabled

## Are there any user-facing changes?

Yes. Spark-compatible formatting of negative decimal values now honors
the parentheses flag. There are no public API or breaking changes.

-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Precedes https://github.com/apache/datafusion/pull/23720.

While displaying a plan with metrics, allow filtering them by name, not
just by category or type.

This is very useful when writing snapshot tests where only a specific
metrics needs to be asserted, without other unrelated metrics polluting
the snapshot assertion.

Regardless of what happens with
https://github.com/apache/datafusion/pull/23720, I think this PR is
still worth it, as it allows creating some really nice `insta` tests
asserting runtime properties reliably by just cherry picking the runtime
metrics relevant for that specific test. This is relevant not only
within DataFusion codebase, but also for other people's codebases using
DataFusion and relying on `insta` for snapshot testing, See an example
of this here:
https://github.com/apache/datafusion/pull/23720/changes#diff-8281405e117428077c19c07afbbe59fed303a3460096e958f761d34f0899b618

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

While displaying metrics, allows filtering them by name

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes, by a new small test.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

People using the metrics display API will be able to filter metrics by
name.

Subject: [PATCH 679/878] perf: optimize `array_empty` udf (#23923)

## Which issue does this PR close?

N/A

## Rationale for this change

I saw that `empty` implementation is inefficient.
I wrote review comments for more why inefficient.

there are some optimizations that do not require benchmark since they
are obvious once you understand, this is one of them

## What changes are included in this PR?
rewrote the function to be fast

## Are these changes tested?
existing tests

## Are there any user-facing changes?
no

Subject: [PATCH 680/878] chore(deps): bump the codeql-actions group with 2
 updates (#23938)

Bumps the codeql-actions group with 2 updates:
[github/codeql-action/init](https://github.com/github/codeql-action) and
[github/codeql-action/analyze](https://github.com/github/codeql-action).

Updates `github/codeql-action/init` from 4.37.1 to 4.37.3

<li>The new address format for the <code>config-file</code> input that
was introduced in CodeQL Action 4.37.0 is now enabled by default. In
addition to the format described there, the <code>remote=</code> prefix
can now be used to explicitly indicate that the input refers to a remote
file. All previous input formats continue to be accepted as well. <a

files from remote repositories that require authentication. This will
allow customers to store their CodeQL configuration in a single
repository that can then be referenced by Default Setup workflows in
other repositories. We expect to roll this and other, related changes
out to everyone in July. <a

<h1>CodeQL Action Changelog</h1>
<p>See the <a
href="https://github.com/github/codeql-action/releases">releases
page</a> for the relevant changes to the CodeQL CLI and language
packs.</p>
<h2>[UNRELEASED]</h2>
<ul>
<li>This version of the CodeQL Action adds support for the
<code>tools</code> input for the <code>codeql-action/init</code> step to
be specified using a <code>github-codeql-tools</code> <a
href="https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization">repository
property</a>. This feature will gradually be rolled out following the
release of this version. Once rolled out, this allows for the CodeQL CLI
version that is used in GitHub-managed workflows, such as Default Setup,
to be set to a custom value. For example, customers who run into issues
with rate limits when a new CodeQL CLI version is released can set the
value to <code>toolcache</code> to always use the CodeQL CLI version
that is available in the runner toolcache. For Advanced Setup workflows,
the value provided for <code>tools</code> in the workflow definition
always takes precedence unless the value of the repository property
starts with <code>!</code>. <a

</ul>
<h2>4.37.1 - 16 Jul 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.20.6 and earlier. These versions of
CodeQL were discontinued on 1 July 2026 alongside GitHub Enterprise
Server 3.16, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3956">#3956</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.1">2.26.1</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4019">#4019</a></li>
</ul>
<h2>4.37.0 - 08 Jul 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.0">2.26.0</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3995">#3995</a></li>
<li>In addition to the existing input format, the
<code>config-file</code> input for the <code>codeql-action/init</code>
step will soon support a new <code>[owner/]repo[@ref][:path]</code>
format. All components except the repository name are optional. If
omitted, <code>owner</code> defaults to the same owner as the repository
the analysis is running for, <code>ref</code> to <code>main</code>, and
<code>path</code> to <code>.github/codeql-action.yaml</code>. Support
for this format ships in this version of the CodeQL Action, but will
only be enabled over the coming weeks. <a

private registries</a> in Default Setup to retrieve CodeQL configuration
files from remote repositories that require authentication. This will
allow customers to store their CodeQL configuration in a single
repository that can then be referenced by Default Setup workflows in

<h1>CodeQL Action Changelog</h1>
<p>See the <a
href="https://github.com/github/codeql-action/releases">releases
page</a> for the relevant changes to the CodeQL CLI and language
packs.</p>
<h2>[UNRELEASED]</h2>
<ul>
<li>This version of the CodeQL Action adds support for the
<code>tools</code> input for the <code>codeql-action/init</code> step to
be specified using a <code>github-codeql-tools</code> <a
href="https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization">repository
property</a>. This feature will gradually be rolled out following the
release of this version. Once rolled out, this allows for the CodeQL CLI
version that is used in GitHub-managed workflows, such as Default Setup,
to be set to a custom value. For example, customers who run into issues
with rate limits when a new CodeQL CLI version is released can set the
value to <code>toolcache</code> to always use the CodeQL CLI version
that is available in the runner toolcache. For Advanced Setup workflows,
the value provided for <code>tools</code> in the workflow definition
always takes precedence unless the value of the repository property
starts with <code>!</code>. <a

</ul>
<h2>4.37.1 - 16 Jul 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.20.6 and earlier. These versions of
CodeQL were discontinued on 1 July 2026 alongside GitHub Enterprise
Server 3.16, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3956">#3956</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.1">2.26.1</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4019">#4019</a></li>
</ul>
<h2>4.37.0 - 08 Jul 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.0">2.26.0</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3995">#3995</a></li>
<li>In addition to the existing input format, the
<code>config-file</code> input for the <code>codeql-action/init</code>
step will soon support a new <code>[owner/]repo[@ref][:path]</code>
format. All components except the repository name are optional. If
omitted, <code>owner</code> defaults to the same owner as the repository
the analysis is running for, <code>ref</code> to <code>main</code>, and
<code>path</code> to <code>.github/codeql-action.yaml</code>. Support
for this format ships in this version of the CodeQL Action, but will
only be enabled over the coming weeks. <a

changelog</a>.</em></p>
<blockquote>
<h1>0.23.0</h1>
<ul>
<li>Added more consts for preconfigured configs and engines</li>
<li>Make DecodeError::InvalidLastSymbol more clear by including the
decoded value</li>
<li>Added SIMD-accelerated engines behind the default-on
<code>simd-unsafe</code> feature: <code>Simd</code> picks the best
instruction set at runtime (AVX2 on <code>x86_64</code>, NEON on
<code>aarch64</code>) and falls back to the scalar
<code>GeneralPurpose</code> engine, while <code>Avx2</code> and
<code>Neon</code> target one instruction set with no runtime
detection and work in <code>no_std</code>. The engines support the
standard and URL-safe alphabets.</li>
<li>Update MSRV to 1.71.0</li>
<li>Add support for custom padding symbols</li>
</ul>

<blockquote>
<h2>v9.0.0 🌈 Change <code>prune-cache</code> default to
<code>false</code></h2>
<h2>Changes</h2>
<p>This release disables the default cache cache pruning to ease the
load on the PyPi infrastructure.
Since users might experience more GitHub Actions cache usage which might
result in higher costs this is marked as a breaking change. To read more
on why we did this (now) you can read the detailed analysis and
reasoning in <a
href="https://redirect.github.com/astral-sh/setup-uv/issues/967">#967</a></p>
<p>Besides this big breaking change we also have a small bugfix while
building caches for linux distributions that behave a big different than
the &quot;big ones&quot; and a speed up in version resolution by only
reading the version manifest until a matching version is found saving
runtime and network bandwith.</p>

Subject: [PATCH 685/878] chore: refactor SortMergeJoin bitwise stream to
 generators and simplify to be textbook like as possible (#23761)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

SortMergeJoin bitwise stream implementation is very complex and hard to
understand while on paper it should be pretty simple.

the reason for that is we have to store state between polls (we had
`boundary`) and handle the case where both can get `Poll::Pending` from
child and `Poll::Ready` from child which further complicate the code

## What changes are included in this PR?

1. Move to async generators
2. Rewrote main loop to be textbook like as possible

(this was entirely written by Claude Fable, sorry, I tried manually but
the code was too complex to hold in my head 😅 )

## Are these changes tested?
existing tests

## Are there any user-facing changes?
The join_time now includes the time to read from the async spill stream
between pending which is arguable more correct since this time is part
of the operator, although long waits between pending calls will be
counted in the op `join_time` while the alternative is not counting the
read from file and decoding...

Subject: [PATCH 686/878] refactor: address review feedback on
 percentile_cont(DISTINCT) accumulator (#23946)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Rationale for this change

Follow-up to post-merge review feedback from @neilconway on #23913.

## What changes are included in this PR?

- Use the fast foldhash `RandomState` for the distinct-value count map
instead of the standard library's default SipHash (the shared
`GenericDistinctBuffer` already does this; the merged fix regressed to
SipHash on this hot path).
- Use `estimate_memory_size` in `size()` instead of a hand-rolled
capacity calculation.
- Adopt the null-free fast path in `update_batch`/`retract_batch` (skip
per-element validity checks when the input has no nulls), mirroring
`GenericDistinctBuffer`.
- Add `ORDER BY` to the sliding-window regression test so its row order
is deterministic.

## Are these changes tested?

Yes — existing percentile unit tests and the full `aggregate.slt` pass.

## Are there any user-facing changes?

No.

Subject: [PATCH 687/878] fix: last value accumulator merge indexing (#23905)

## Which issue does this PR close?

- Related to apache/datafusion-comet#4131.

## Rationale for this change

`TrivialLastValueAccumulator::merge_batch` filtered out unset states but
then read row `0` from the remaining value array. As a result, merging
multiple `LAST_VALUE` partial states returned the first valid state
instead of the last one.

## What changes are included in this PR?

- Select the final valid state row when merging unordered `LAST_VALUE`
states.
- Extend the existing merge test to verify the evaluated result.

## Are these changes tested?

Yes:

<h2>3.0.0</h2>
<p>This release contains adjustments to the syntax tree to account for
ongoing Rust language development from the 3 years since syn 2.0.0 and
to anticipate some in-flight Rust language RFCs.</p>
<p>These include: default values in fields, pinned type sugar, raw
lifetimes, generator blocks and functions, unnamed enum variants,
attributes in tuple types and tuple patterns, named arguments in
parenthesized generic argument lists, lightweight clones, const traits,
const function pointers, mutability restricted fields, supertrait auto
implementation, final associated functions, trait implementability
restrictions, const blocks in path arguments, item-level const blocks,
return type notation, never patterns, function delegation, mutable
by-reference bindings, in-place initialization, field projections,
explicitly dyn-compatible traits, view types, file-level frontmatter,
generic const arguments, guard patterns, lazy type aliases, explicitly
safe foreign items, super let, unsafe fields, pattern types,
heterogeneous try-blocks, function contracts, async function trait
bounds, static closure coroutine syntax, unsafe binder types, move
expressions, for-await loops, and postfix keywords.</p>

<h1>Breaking changes</h1>
<h2>Modifiers</h2>
<p>To reserve more room for language evolution, there are 10 new
non-exhaustive structs in the syntax tree having the following
commonality:</p>
<ul>
<li>
<p>Name ending in <code>Modifiers</code>. {<code>BlockModifiers</code>,
<code>ClosureModifiers</code>, <code>ConstModifiers</code>,
<code>FieldModifiers</code>, <code>FnModifiers</code>,
<code>ImplModifiers</code>, <code>LocalModifiers</code>,
<code>TraitBoundModifiers</code>, <code>TraitModifiers</code>,
<code>TypeModifiers</code>}</p>
</li>
<li>
<p>Each implements <code>Default</code>. The default value is guaranteed
to comprise no tokens.</p>
</li>
<li>
<p>Non-exhaustive. Can only be instantiated by Syn's parser or by
creating and then mutating <code>▁▁Modifiers::default()</code>.</p>
</li>
<li>
<p>Does not implement <code>Parse</code>. When parsing, they are parsed
by the enclosing syntax tree node.</p>
</li>
<li>
<p>Does not implement <code>ToTokens</code>. In some cases the syntax
that these nodes might hold in the future is not necessarily contiguous
tokens.</p>
</li>
<li>
<p>Provides <code>.require_empty() -&gt; Result&lt;()&gt;</code> which
returns a meaningfully spanned error if the modifiers are different from
the empty default. This enables a caller to reject syntax it does not
recognize without knowing what that syntax may be.</p>
</li>
</ul>
<h2>Types</h2>
<ul>
<li>
<p><code>Type::BareFn</code> has been renamed to
<code>Type::FnPtr</code> to mirror the compiler's terminology. Together
with this, <code>BareVariadic</code> is renamed to
<code>FnPtrVariadic</code>.</p>
</li>
<li>
<p>The mutually exclusive <code>const_token</code> and
<code>mutability</code> fields of <code>Type::Ptr</code> have been
unified into an enum of type <code>PointerMutability</code>, which was
already previously used by <code>Expr::RawAddr</code>.</p>
</li>
<li>
<p>Every <code>Type</code> variant now holds attributes, which can
represent the attributes of element types inside a tuple type, or
attributes for a function return type.</p>
</li>
<li>
<p><code>BareFnArg</code> is renamed to <code>NamedArg</code> and is
used in <code>ParenthesizedGenericArguments</code>, in addition to the
existing use in <code>Type::FnPtr</code>.</p>
</li>
</ul>
<h2>Expressions</h2>
<ul>
<li>In <code>Expr::Closure</code>, the fields <code>or1_token</code> and
<code>or2_token</code> have been renamed to <code>inputs_begin</code>
and <code>inputs_end</code> to indicate the beginning and ending
<code>|</code> token of the closure inputs.</li>
</ul>

Subject: [PATCH 689/878] feat: support `ansi` for `elt` (#23928)

Part of https://github.com/apache/datafusion/issues/23929

## Rationale for this change

Spark's `elt` errors on out-of-range indices when ANSI is on, and
returns `NULL` when off. DataFusion previously always returned `NULL`
(there was a `TODO` for this in the source).

  ## What changes are included in this PR?

- `elt.rs`: read `enable_ansi_mode` from
`ScalarFunctionArgs::config_options`; raise `"The index N is out of
bounds. The array has M elements."` in ANSI mode, keep `NULL` behavior
otherwise. `NULL` index
  always returns `NULL`.
- `elt.slt`: add missing ANSI-off cases (index 0, negative, large,
`NULL` index, `NULL` value, vectorized) and a full ANSI-on section with
`statement error` assertions.

  ## Are these changes tested?

  Yes. New Rust unit tests and sqllogictest cases cover both modes.

  ## Are there any user-facing changes?

With `enable_ansi_mode = true`, `elt` on invalid indices now errors
instead of returning `NULL`. Default behavior unchanged. No API changes.

Subject: [PATCH 691/878] feat(physical-plan): generic Rows-backed GroupColumn
 keeps mixed schemas on the column-wise path (#23523)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #22715 (nested type coverage in `GroupValuesColumn` EPIC)
- Alternative to #23128 (per-type approach) — implements the direction
@alamb proposed in
<https://github.com/apache/datafusion/pull/23128#issuecomment-4903031891>
- Step toward the terminal goal of retiring `GroupValuesRows` entirely
(#23404)

## Rationale for this change

Today `GroupValuesColumn` is **all-or-nothing**: a single nested column
in the GROUP BY key (\`Struct\`, \`List\`, \`FixedSizeList\`, …) makes
\`supported_schema\` return \`false\` and drops the *entire* aggregation
onto the row-wise \`GroupValuesRows\` fallback — even when every other
column would have qualified for the column-wise fast path. For a \`GROUP
BY int_col, struct_col\` shape, the \`int_col\` pays the row-encoded
storage cost for no reason.

## What changes are included in this PR?

Add \`RowsGroupColumn\`: a generic \`GroupColumn\` backed by a
single-field \`RowConverter\`, wired in as the nested-type dispatch arm
of \`group_column_supported_type\` / \`make_group_column\`. Native
columns keep their type-specialized builders; the nested column pays
row-encoding only for its one column.

Gated to \`data_type.is_nested()\` so intentionally excluded scalar
types (Float16, Decimal256) stay on \`GroupValuesRows\` and the
\`group_column_supported_type\` ⇔ \`make_group_column\` invariant holds.

## Impact

Memory, measured with 4000 groups of \`8 × Int64 + 1 ×
FixedSizeList<Int64, 4>\` in
\`mixed_schema_column_path_uses_less_memory_than_rows_fallback\`:

| | Bytes | vs baseline |

|-------------------------------------------------------|----------|-------------|
| \`GroupValuesRows\` (today's fallback) | 1096 KB | 100% |
| \`GroupValuesColumn\` + \`RowsGroupColumn\` fallback | 594 KB |
**54.2%** |

Speed: not benchmarked as a headline result — the wins come from native
columns keeping their type-specialized \`equal_to\`/\`append_val\` fast
paths instead of falling back to byte-encoded row comparisons.

## Are these changes tested?

Yes:

- Unit tests inside \`row_backed\`: FSL / Struct roundtrip, \`take_n\`,
\`supports_type\` matches \`RowConverter::supports_fields\`.
- \`mixed_schema_column_path_uses_less_memory_than_rows_fallback\`
(mod.rs): the 54.2% memory claim + identical group assignment vs
\`GroupValuesRows\`.
- \`nested_float_edge_cases_match_rows_fallback\`: nested \`-0.0\` /
\`NaN\` produce the same groupings as \`GroupValuesRows\` (the
correctness invariant to watch, since hashing runs on the raw column and
equality runs on the row bytes).
- \`multi_batch_and_emit_first_matches_rows_fallback\`: multi-batch
streaming intern + \`EmitTo::First\` + \`take_n\`.

All 39 tests in \`aggregates::group_values\` pass.

## Are there any user-facing changes?

No — internal aggregation representation only. Same query results, lower
memory footprint on mixed-schema GROUP BY keys.

## Follow-ups (out of scope)

- Add coverage for any type \`RowConverter\` cannot encode (currently
arrow-rs 59.x handles Map fine; \`supports_type\` delegates to
\`RowConverter::supports_fields\` so it auto-tracks upstream).
- Retire \`GroupValuesRows\` entirely once coverage is complete
(#23404).

+//! A generic [`GroupColumn`] backed by the arrow row format.
+//!
+//! Unlike the type-specialized builders in this module (primitive, byte,
+//! boolean, ...), [`RowsGroupColumn`] works for *any* data type that arrow's
+//! [`RowConverter`] can encode — including nested types such as `Struct`,
+//! `List`, `LargeList` and `FixedSizeList`. It stores one group value per row
+//! in a single-column [`Rows`] buffer and compares group keys by their encoded
+//! bytes.
+//!
+//! # Why this exists
+//!
+//! [`GroupValuesColumn`] can only be used when *every* column of the group-by
+//! key has a [`GroupColumn`] implementation; otherwise the whole aggregation
+//! falls back to the row-wise [`GroupValuesRows`], which is materially slower
+//! and heavier for the columns that *would* have qualified for the column-wise
+//! fast path. By providing a generic fallback `GroupColumn`, a schema like
+//! `GROUP BY int_col, struct_col` keeps `int_col` on its fast native builder
+//! and only pays the row-encoding cost on `struct_col`, instead of dragging both
+//! columns onto `GroupValuesRows`.
+//!
+//! # Relationship to hashing
+//!
+//! This column does not hash anything itself: [`GroupValuesColumn`] hashes the
+//! raw input columns via `create_hashes`, which already supports nested types.
+//! Equality is decided here by comparing arrow-row bytes. For the two to agree
+//! on group identity, values that this column considers equal must hash equal —
+//! see the float `-0.0` / `NaN` note on [`RowsGroupColumn`].
+//!

+/// A [`GroupColumn`] that stores group values for a single column in the arrow
+/// [row format], backed by a single-field [`RowConverter`].
+///
+/// # NULL semantics
+///
+/// The [`GroupColumn`] contract treats two NULLs as equal. The row format
+/// encodes NULL with a distinct sentinel, so `null`-row bytes compare equal to
+/// each other and unequal to any non-null row — matching the contract without
+/// special-casing.
+///
+/// # Float `-0.0` / `NaN`
+///
+/// Equality here is byte equality under arrow's IEEE-754 *totalOrder* row
+/// encoding, which treats `-0.0` and `+0.0` as distinct and canonicalizes
+/// `NaN`. Because hashing is performed separately (on the raw input array), a
+/// caller must ensure the two agree — e.g. by normalizing `-0.0 → +0.0` on the
+/// input columns before hashing when a float leaf is present (as
+/// [`GroupValuesRows`] does). See the module docs.

Subject: [PATCH 692/878] perf: `array_agg()` performance improvements (#23716)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23715.

## Rationale for this change

Queries using `array_agg(DISTINCT col)` were significantly slower than
expected.

Profiling revealed that `DistinctArrayAggAccumulator::update_batch` was
allocating a
heap-owned `String` on every single input row — even for rows whose
value was already
present in the accumulator. For a typical low-cardinality workload (e.g.
a column of ~25
database names across thousands of rows), this meant paying the full
allocation cost for
every duplicate, which dominated the runtime.

## What changes are included in this PR?

This PR applies the same deduplication strategy already used by
`AggregateExec` for
`GROUP BY`: duplicate rows now cost only a hash probe with no heap
allocation, and new
distinct values are appended to a single shared buffer rather than
allocated individually.
The fix applies to all column types, not just strings, and
`retract_batch` support
(required for sliding window frames such as `ROWS BETWEEN N PRECEDING
AND CURRENT ROW`)
is fully preserved.

## Are these changes tested?

Four unit tests were added to `DistinctArrayAggAccumulator` — one each
for `Utf8`,
`Int64`, `Float64`, and `Date32` — to pin the deduplication contract
across the most
common column types and serve as a regression guard for future changes.
The existing
sliding window sqllogictest suite (`array_agg_sliding_window.slt`)
covers `retract_batch`
correctness end-to-end and passes unchanged.

Two `update_batch` micro-benchmarks were added to measure the
before/after on realistic
data: one with low cardinality (~25 distinct database names in 8 192
rows, modelling the
common production case) and one with high cardinality (~7 800 distinct
values, modelling
the worst case where almost every row is new). Results on an 8 192-row
batch:

| Benchmark | Before | After | Speedup |
|---|---|---|---|
| Low cardinality (~25 distinct DB names) | 648.6 µs | 189.4 µs |
**3.42×** |
| High cardinality (~7 800 distinct values) | 1078.3 µs | 269.4 µs |
**4.00×** |


## Are there any user-facing changes?

No user-facing changes

No breaking changes to public APIs

Subject: [PATCH 693/878] fix: accept LargeUtf8 and Utf8View patterns in
 SIMILAR TO planning (#23735)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23732

## Rationale for this change

Follow-up to #23704, which made the `TypeCoercion` analyzer coerce
`SIMILAR TO` operands to a common string type. The SQL planner still
rejects `LargeUtf8` and `Utf8View` **patterns** before the analyzer ever
runs:

```sql
SELECT s FROM test, patterns WHERE s SIMILAR TO arrow_cast(pat, 'Utf8View');
-- error: Invalid pattern in SIMILAR TO expression
```

Now that the analyzer coerces both operands, this planner restriction is
unnecessary (and inconsistent with `LIKE`, whose planner path has no
such check).

## What changes are included in this PR?

- `datafusion/sql/src/expr/mod.rs`: the pattern-type check in
`sql_similarto_to_expr` now accepts `Utf8` / `LargeUtf8` / `Utf8View` /
`Null` instead of only `Utf8` / `Null`.
- `datafusion/sqllogictest/test_files/type_coercion.slt`: regression
tests with non-literal `Utf8View` and `LargeUtf8` patterns (plus a `NOT
SIMILAR TO` case), next to the existing #22886 regression tests.

The planner relaxation and tests were originally part of #22887; this PR
lands the remaining piece of it.

## Are these changes tested?

Yes — new sqllogictest cases in `type_coercion.slt`. The existing
planner rejection of non-string patterns (`SELECT 'a' SIMILAR TO 1`)
still errors as before.

## Are there any user-facing changes?

Yes: `SIMILAR TO` queries with non-literal `LargeUtf8` / `Utf8View`
patterns that previously failed during SQL planning with `Invalid
pattern in SIMILAR TO expression` now plan and execute successfully. No
breaking API changes.

Subject: [PATCH 694/878] Fill in missing utf8view support in function type
 coercion (#23916)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #13363

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Fill in some missing support for utf8view (and date64) in function type
coercion. Main affected functions are UDFs that use exact/uniform type
signature; for example in `date_bin` it couldnt coerce utf8view to its
input types (even though utf8 worked)

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Add support for casting to/from utf8view in some arms.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

No

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 695/878] perf: Optimize hashing, null-free fast path for
 `percentile_cont`, `median` (#23954)

## Which issue does this PR close?

- Closes #23953

## Rationale for this change

This PR makes three improvements to non-distinct
`PercentileContAccumulator` and `MedianAccumulator`, inspired by recent
work on `percentile_cont(DISTINCT)` (#23946):

1. Switch from SipHash to foldhash for internal hash maps
2. Add a null-free fast path to `update_batch` and `retract_batch`
3. Raise an error if we attempt to retract an unknown value in
`retract_batch`, rather than silently ignoring it.

Benchmarks:

percentile_cont no_nulls window=256 -61.1% (249.0 -> 96.6 us)
percentile_cont with_nulls window=256 -59.4% (232.7 -> 94.5 us)
percentile_cont no_nulls window=4096 -50.9% (756.3 -> 370.4 us)
percentile_cont with_nulls window=4096 -48.2% (552.2 -> 286.2 us)
percentile_cont no_nulls window=16384 -47.3% (2.311 -> 1.218 ms)
percentile_cont with_nulls window=16384 -42.0% (1.465 -> 0.851 ms)
median no_nulls window=256 -62.8% (247.0 -> 92.0 us)
median with_nulls window=256 -59.8% (228.8 -> 92.0 us)
median no_nulls window=4096 -40.0% (411.4 -> 246.6 us)
median with_nulls window=4096 -39.4% (364.4 -> 221.0 us)
median no_nulls window=16384 -31.5% (1.107 -> 0.759 ms)
median with_nulls window=16384 -32.9% (0.947 -> 0.637 ms)

## What changes are included in this PR?

See above.

## Are these changes tested?

Yes: existing tests pass, new tests added for the null-free fast path
and the improved error handling.

## Are there any user-facing changes?

No.

Subject: [PATCH 696/878] perf: null-free fast path for COUNT(DISTINCT)
 primitive accumulator (#23956)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23955.

## Rationale for this change

`PrimitiveDistinctCountAccumulator::update_batch` does a per-element
validity check on every row even when the array has no nulls. Its own
`merge_batch` already inserts wholesale from the values buffer, so the
same fast path applies to `update_batch`. Inspired by the null-free fast
paths added to `percentile_cont`/`median` in #23954.

## What changes are included in this PR?

- When `null_count() == 0`, insert directly from the values buffer
(`self.values.extend(arr.values().iter().copied())`) instead of the
per-element `Option` check.
- Unit test asserting the fast and general paths agree (a dense array
and a null-containing array with the same non-null values yield the same
distinct count).

## Benchmarks

`count_distinct` benchmark, null-free 8192-row batches:

```
count_distinct i64 80% distinct   -67.0%  (54.9 -> 18.1 us)
count_distinct i64 99% distinct   -66.0%  (54.9 -> 18.7 us)
count_distinct u32 80% distinct   -66.9%  (53.9 -> 17.8 us)
count_distinct u32 99% distinct   -65.3%  (53.3 -> 18.5 us)
count_distinct i32 80% distinct   -66.9%  (54.1 -> 17.9 us)
count_distinct i32 99% distinct   -66.2%  (53.2 -> 18.0 us)
```

The bitmap-backed cases (u8/i8/u16/i16) and the grouped-accumulator
cases don't use this path and are unchanged, as expected.

## Are these changes tested?

Yes — new unit test; existing count-distinct tests pass.

## Are there any user-facing changes?

No.

Subject: [PATCH 698/878] test: add regression coverage and docs for NULL
 format handling (#23669)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- None — follow-up to #23640 and #23641.

## Rationale for this change

#23641 already shipped the implementation for NULL string and format
arguments. Per the review request on this PR, this follow-up keeps only
the documentation and regression coverage needed to prevent a
recurrence.

## What changes are included in this PR?

- Documents that NULL format entries are skipped and an all-NULL format
list returns NULL for `to_date`, all `to_timestamp*` variants, and
`to_unixtime`.
- Adds an Arrow validity-buffer regression test where a NULL format slot
retains parseable backing bytes and must not win over a later valid
format.
- Adds SQL logic tests for NULL-format error propagation and
validation-before-NULL-input ordering.

## Are these changes tested?

- `cargo fmt --all`
- `cargo test --locked -p datafusion-functions`
- `cargo test --locked --profile ci --test sqllogictests -- dates.slt`
- `cargo clippy --locked -p datafusion-functions --lib --tests -- -D
warnings`
- `./ci/scripts/doc_prettier_check.sh --write --allow-dirty`
- Mutation check: removing the shared NULL guard makes the
retained-bytes regression test fail; restored code passes.

## Are there any user-facing changes?

No behavior change. The generated function documentation now describes
behavior already shipped in #23641.

Subject: [PATCH 699/878] fix: preserve aggregate filter pushdown order
 (#22926)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22925.

## Rationale for this change

`FilterPushdown` maps each child pushdown result back to its original
parent
filter by position. `AggregateExec::gather_filters_for_pushdown`
previously
split parent filters into safe and unsafe buckets and then concatenated
the
results, which changed their order.

For example, in `cnt@2 = 1 AND b@1 = bar`, the grouping-column predicate
on
`b` can cross the aggregate, while the predicate on aggregate output
`cnt`
must remain above it. Reordering the returned results could make the
optimizer
associate the pushed-down `b` result with the `cnt` predicate and
incorrectly
remove the latter.

Aggregate pushdown also needs to account for empty-input semantics. A
global
aggregate, or a grouping-sets aggregate containing `()`, can emit a row
even
when its input is empty. Moving any parent predicate below such an
aggregate —
including a column-free predicate such as `false` — can therefore change
the
result.

## What changes are included in this PR?

- Preserve parent-filter order by constructing each child description
once
  with `ChildFilterDescription::from_child_with_allowed_indices`.
- Allow only grouping-output columns that are present in every grouping
set;
  aggregate-result columns remain above the aggregate.
- Mark all parent filters unsupported for global aggregates and grouping
sets
  containing an empty grouping set, while retaining aggregate-generated
  dynamic filters.
- Validate that every child returns one parent-filter result per input
filter
  before positional remapping.
- Add physical optimizer and SQL regression coverage for mixed filter
order,
global-aggregate name collisions, constant predicates, and grouping
sets.

## Are these changes tested?

Yes:

- `cargo test -p datafusion --test core_integration
physical_optimizer::filter_pushdown`
- `cargo fmt --all -- --check`
- `cargo check -p datafusion-physical-plan -p
datafusion-physical-optimizer`
- `git diff --check upstream/main`
- Full GitHub CI, including Rust tests, clippy, and sqllogictests

## Are there any user-facing changes?

There are no public API changes. Filter pushdown now preserves mixed
aggregate
predicates correctly and avoids moving predicates across aggregates when
doing
so could change empty-input results.

Subject: [PATCH 700/878] minor(test): cover partially ordered aggregate
 spilling (#23947)

## Which issue does this PR close?
- Not closes but part of #13431

## Rationale for this change
`GroupedHashAggregateStream` supports spilling for partially sorted
group input, but existing aggregate spill tests only cover unordered
(`GroupOrdering::None`) input. The `GroupOrdering::Partial` +
`OutOfMemoryMode::Spill` path, including spilling sorted intermediate
state and merging it back, does not have direct coverage.

## What changes are included in this PR?
added test coverage for the case above

## Are these changes tested?
test only change and it can be tested via:

```
cargo test --test sqllogictests -- ordered_aggregate_spill
```

## Are there any user-facing changes?
no test only change

Subject: [PATCH 701/878] feat: centralizing higher-order list lambda
 evaluation helpers (#23911)

## Which issue does this PR close?

- Closes #23667

## Rationale for this change

`array_filter`, `array_any_match`, and `array_first` each implement
their own version of the same higher-order list execution pattern:

- normalize a list-like argument to List / LargeList,
- extract the flattened child values with slice-aware semantics,
- evaluate a lambda once over the flattened values,
- spread captured outer columns to flattened row cardinality with
list_values_row_number,
- map the flattened lambda result back to one output value per input row
using adjusted offsets and null-row handling.

This PR introduces shared helpers that allow for one area where the
shared logic lives

## What changes are included in this PR?

Added a helper in `lambda_utils` that abstracts shared fields (original
list/flat values/evaluated result) and functionality (creating the
`BooleanArray`, adjusting offsets for `List`/`LargeList`, extracting
`list`/`lambda` pairs, etc), and applying to
`array_filter`/`array_first`/`array_any_match`

## Are these changes tested?

Yes

## Are there any user-facing changes?

No - shared helpers added are only visible within in the crate, rest is
just rewrites

Subject: [PATCH 702/878] fix(common): preserve an exact zero through filter
 selectivity estimation (#23936)

## Which issue does this PR close?

- Part of #8227.

## Rationale for this change

`Precision::with_estimated_selectivity` always demoted to inexact, so
`Exact(0)` became `Inexact(0)`. Scaling zero by any selectivity is still
exactly zero: filtering a provably empty input cannot produce rows.

Because operators widen exact to inexact, emptiness could not propagate
up a plan through statistics at all, it was lost at the first
`FilterExec`. That operator already preserved the exact zero for a
contradictory predicate and for column byte sizes, so the same fact came
out exact or inexact depending on the path taken.

This is the same reasoning as #23670, which stops
`FileScanConfig::statistics()` demoting an exact zero when a filter is
present, applied one level up. The two are independent, but together
they let a proof of emptiness survive from the scan through the filter.

## What changes are included in this PR?

- `with_estimated_selectivity` returns an exact zero unchanged.
`Inexact(0)` is untouched: an estimate of zero is not a proof of zero.
- `scale_byte_size` in `filter.rs` is removed, subsumed by the above.

## Are these changes tested?

Yes. A unit test for the method, and a `FilterExec` test that a
satisfiable predicate over an exactly empty input keeps `num_rows`,
`total_byte_size` (proving that `scale_byte_size` can be safely removed)
and column `byte_size` exact.

`test_filter_statistics_empty_input_equality_ndv_zero` asserted
`Inexact(0)` and now asserts `Exact(0)`, which is expected.

## Are there any user-facing changes?

No breaking changes. `Precision::with_estimated_selectivity` is public
and keeps its signature, but its documented contract changes: it
previously stated it would always return inexact statistics, and it now
preserves an exact zero. Callers relying on the old wording will see
`Exact(0)` where they saw `Inexact(0)`. This is an improvement and could
be arguably considered a bug-fix, so I consider this contract change
justified.

`FilterExec` over a provably empty input therefore reports exact
statistics, visible in `EXPLAIN` output that shows statistics.

----

Disclaimer: I used AI to assist in the code generation, I have manually
reviewed the output and it matches my intention and understanding.

Subject: [PATCH 706/878] fix: preserve dictionary-value nulls in scalar regex
 operators (#23966)

## Which issue does this PR close?

- Closes #23963.

## Rationale for this change

The scalar regex fast path for Dictionary arrays evaluates each
dictionary value once and gathers the resulting booleans with
`BooleanArray::take_iter`. That gather preserves null keys but drops
null validity from the evaluated dictionary values. A key referencing a
null dictionary value therefore becomes valid `false`, and negated regex
operators can incorrectly turn it into `true`.

This is distinct from #23722, which updates the array-pattern
`regex_match_dyn` path. This PR fixes null propagation in
`regex_match_dyn_scalar`.

## What changes are included in this PR?

- Replace the validity-dropping dictionary gather with Arrow `take`,
preserving both key validity and evaluated child validity.
- Add a physical-expression regression test for `RegexMatch`,
`RegexIMatch`, `RegexNotMatch`, and `RegexNotIMatch`. The test covers a
null key and a key referencing a null dictionary value, and compares the
Dictionary result with the equivalent cast-to-`Utf8` evaluation.

## Are these changes tested?

Yes.

- Focused regression: 1 passed.
- `datafusion-physical-expr`: 1,649 passed, including the new
regression.
- Remaining workspace: 7,928 passed, 0 failed, 7 ignored; sqllogictest
completed 499/499 files.
- `datafusion` library: 461 passed.
- `datafusion` core integration: 1,057 passed; four local
memory-validation runners exceeded their host RSS thresholds and were
isolated as environment-sensitive, unrelated to this patch.
- `datafusion-cli`: 106 passed.
- Formatting, workspace clippy with warnings denied, TOML formatting,
license headers, changed-file typo checks, and `git diff --check`
passed.

## Are there any user-facing changes?

Dictionary-encoded string inputs now preserve SQL null semantics for
scalar regex operators. There are no public API changes.

Subject: [PATCH 709/878] Add benchmarks for hashjoin candidate equality
 filtering (#23980)

## Which issue does this PR close?

- Part of #23237.

## Rationale for this change

Issue #23237 identifies hash join candidate equality filtering as a
potential
performance bottleneck. Before changing that implementation, we need
stable
benchmarks that reproduce the relevant workloads and let us measure the
effect
of a proposed optimization independently.

The existing hash join benchmark suite covers high-fanout joins, but it
does
not isolate these two cases:

1. A single hot hash bucket in which all build-side rows use the same
long
   string key.
2. A skewed composite-key join in which candidate pairs must be checked
across
   multiple key columns.

This PR intentionally adds only the benchmarks. The implementation
change for
`equal_rows_arr` will be submitted separately so that the benchmark
workloads
can be reviewed and established independently of the optimization.

## What changes are included in this PR?

This PR adds two hash join benchmarks:

- **Q24: single-hot-bucket long string-key join**
  - Creates 3,000 build-side rows with the same long string key.
  - Selects matching probe-side rows that use that same key.
- Causes every selected probe row to fan out across the entire
build-side
    bucket.
  - Uses `count(*)` so the benchmark emphasizes hash match and candidate
equality processing without materializing and retaining the full joined
    output.

- **Q25: skewed composite-key join**
  - Uses an integer key and a long string key.
- Distributes the build-side integer key over 256 values while all
selected
    probe rows use one value.
- Produces a high-fanout set of candidate matches for one integer-key
value.
- Requires the second string-key column to be checked as part of
composite
    join-key equality.
  - Uses `count(*)` to focus the measurement on the join match path.

Both benchmarks:

- Assert that the input data is available.
- Assert that the physical plan contains `HashJoinExec`.
- Use the no-statistics configuration and force Partitioned hash join
mode.
- Are registered in the `hj` benchmark runner with descriptive
build/probe
  metadata.
- Can be used to compare the existing implementation against the
follow-up
  optimization for #23237.

## Are these changes tested?

No hash join implementation is changed by this PR.


## Are there any user-facing changes?

No.

Subject: [PATCH 710/878] docs: Fixes incorrect type name in
 `UserDefinedLogicalNode` comment (#23992)

## Which issue does this PR close?

- N/A. This fixes a trivial doc comment. No issue filed.

## Rationale for this change

The doc comment in `datafusion/expr/src/logical_plan/extension.rs`
incorrectly said it "derives UserDefinedLogicalNode to
`UserDefinedLogicalNode`" ( It named the same type twice ). This PR
fixes this trivial documentation.

## What changes are included in this PR?

A single line containing the documentation fix, which corrects the
source trait name from `UserDefinedLogicalNode` to
`UserDefinedLogicalNodeCore`.

## Are these changes tested?

No tests needed as this is a comment-only change.

## Are there any user-facing changes?

No.

Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`to_time` previously parsed the Chrono format strings for every non-null
input value. For array inputs, this repeated the same format parsing for
each row in a batch.

This PR precompiles the format strings once per udf invocation and
reuses the compiled format items while parsing each value.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Precompile and reuse the to_time format strings.
- Add tests for multiple formats and NULL values.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes. Existing tests pass, and new slt coverage was added for multiple
formats and NULL values.

## Are there any user-facing changes?

No. This is an internal performance optimization.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

Subject: [PATCH 712/878] Optimize Spark hex null handling (#23688)

## Which issue does this PR close?

- Closes #23674.

## Rationale for this change

Spark hex encoding preserves input validity exactly, but the byte-array
path rebuilt the null bitmap row by row and always iterated through
`Option` values. The input arrays already expose both the original
`NullBuffer` and an all-valid fast path.

## What changes are included in this PR?

- pass the byte array accessor into `hex_encode_bytes` so the output can
clone and reuse the input `NullBuffer`
- split nullable and no-null loops, avoiding per-row validity checks
when the input has no null buffer
- preserve exact offset, overflow, casing, dictionary, and null
semantics
- add a sliced-array regression that verifies semantic equality and
bitmap pointer reuse
- add no-null output coverage and dedicated UTF-8/binary Criterion cases

## Are these changes tested?

Yes.

- `cargo test -p datafusion-spark function::math::hex --lib`: 10 passed
- `cargo fmt --all -- --check`: passed
- `cargo clippy -p datafusion-spark --all-targets --all-features
--no-deps -- -D warnings`: passed
- `git diff --check`: passed
- benchmark target compiled with `--features core`

The workspace dependency clippy invocation without `--no-deps` reaches
an unrelated existing `dead_code` warning in
`datafusion/physical-expr/src/expressions/dynamic_filters/mod.rs:464`;
the changed crate is clean.

### Benchmark

Command (same warmed build and profile for upstream `main` and this
branch):

```bash
CARGO_BUILD_JOBS=2 \
CARGO_PROFILE_BENCH_LTO=false \
CARGO_PROFILE_BENCH_CODEGEN_UNITS=16 \
cargo bench -p datafusion-spark --features core --bench hex -- \
  'hex_(utf8|binary)_no_nulls'
```

Mean times from the immediate upstream-then-branch sequence:

| case | upstream main | this PR | change |
| --- | ---: | ---: | ---: |
| UTF-8, 1,024 rows | 79.895 us | 59.181 us | -25.9% |
| UTF-8, 4,096 rows | 317.64 us | 244.88 us | -22.9% |
| UTF-8, 8,192 rows | 509.64 us | 411.27 us | -19.3% |
| Binary, 1,024 rows | 86.135 us | 40.600 us | -52.9% |
| Binary, 4,096 rows | 346.16 us | 253.13 us | -26.9% |
| Binary, 8,192 rows | 635.98 us | 424.78 us | -33.2% |

## Are there any user-facing changes?

No API or behavior changes. This is an internal performance optimization
for Spark-compatible hex expressions.

Subject: [PATCH 713/878] fix(datasource): avoid over-conservative
 transformation of num_rows statistics in file scan config (#23670)

## Which issue does this PR close?

Minor fix I stumbled across. There is no issue (I can create one if this
warrants discussion).

## Rationale for this change

If the file scan is guaranteed to have no results (`num_rows ==
Precision::Exact(0)`), filtering them does not change the result. It
will be zero anyway.

## What changes are included in this PR?

Only change `Exact` -> `Inexact` if there are non-zero rows

## Are these changes tested?

Yes.

## Are there any user-facing changes?

It can happen that the optimizer can now better optimize the query plans
(which we are looking forward to).

Subject: [PATCH 714/878] refactor(proto): migrate scalar subquery serde
 (#23915)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23515.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

ScalarSubqueryExpr nodes must share the results container populated by
their enclosing ScalarSubqueryExec. A normal child decode loses that
scope when serialization moves into the plan implementation.

Add a scoped child decode operation so the new plan hooks preserve the
shared container while removing the central serialization path.


## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 715/878] refactor: mark the ExecutionPlan proto dispatch
 traits as non-public API (#24001)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #23494. Precursor to #23915 (and to the remaining `DataSource`
/ `DataSink` items, #23497 / #23498).

## Rationale for this change

`ExecutionPlanEncode` / `ExecutionPlanDecode` (added in #23495) are
dispatch details of the
`try_to_proto` / `try_from_proto` hooks, not extension points. They are
defined in
`datafusion-physical-plan`, implemented only by `ConverterPlanEncoder` /
`ConverterPlanDecoder`
in `datafusion-proto`, and plans reach them exclusively through
`ExecutionPlanEncodeCtx` /
`ExecutionPlanDecodeCtx` — their own docs already say so:

> Internal dispatch trait backing [`ExecutionPlanEncodeCtx`].
Implemented by `datafusion-proto`.
> Plan authors never name this trait.

They are `pub` only because those adapters live in another crate.
Nothing said that to the tooling,
so every capability the epic still has to add to the ctx reads as a
major breaking change. #23915
hits this first: it needs `decode_plan_with_scalar_subquery_results` so
`ScalarSubqueryExec` can
decode its input with the subquery-results container in scope, and
`cargo-semver-checks` flags the
required method as `trait_method_added`. The `DataSource` / `DataSink`
families will want their own
primitives next.

`#[doc(hidden)]` states what was already true, and makes those additions
changes to something that
was never public API — rather than asking each follow-up PR to explain
away a breakage report.

## What changes are included in this PR?

Mark `ExecutionPlanEncode` and `ExecutionPlanDecode` `#[doc(hidden)]`,
and say why in their docs
and in the module overview. One file, no behavior, wire-format, or
signature changes.

A sealed-trait supertrait was the first thing I tried. It is worse here:
sealing across a crate
boundary needs a `pub` marker anyway, so it does not actually prevent a
downstream impl — it just
adds a public item in order to say "this is not public API", plus an
`impl` line for every
implementor including test doubles. `#[doc(hidden)]` says the same thing
by removing API surface
instead of adding it, and `cargo-semver-checks` honors both identically
(measured below).

## Are these changes tested?

The property this PR buys is a `cargo-semver-checks` classification, so
it is verified with that
tool directly — v0.49.0, the version CI installs, invoked the way CI
invokes it:

| baseline | change under test | result |
|---|---|---|
| `main` | add a required method to `ExecutionPlanDecode` |
`trait_method_added` — **major** |
| this PR | the same required method | 223 checks pass, **no semver
update required** |

Worth recording, since it drove the shape of this PR: the lint reads
`public_api_sealed` from the
**baseline**, so this has to land before the PRs that add methods, not
alongside them. Also,
`cargo-semver-checks` does not re-qualify the traits as public API even
though
`ExecutionPlanEncodeCtx::new` still names them in a public signature.

Also ran, on the pinned 1.97.0 toolchain: `cargo fmt --all -- --check`,
`cargo clippy --all-targets
--all-features` for both crates, `cargo doc` with `-D warnings` (no
broken intra-doc links from the
module docs to the now-hidden traits), and the full `datafusion-proto`
integration suite
(211 passed).

## Are there any user-facing changes?

`cargo-semver-checks` will report `trait_now_doc_hidden` on this PR, and
that is the intended
content of the change.

Real-world impact is nil: both traits were introduced by #23495, which
merged after `54.1.0` was
tagged, so no released version of `datafusion-physical-plan` contains
them. The load-bearing public
API — `ExecutionPlan::try_to_proto`, the two ctx types,
`AsExecutionPlan`, `PhysicalExtensionCodec`,
`PhysicalProtoConverterExtension` — is untouched, and `datafusion-proto`
needs no change at all.

Note for contributors on #23494: the expression-side equivalents
(`PhysicalExprEncode` /
`PhysicalExprDecode` in `physical-expr-common`) have the same shape and
the same argument, but
several test doubles across crates implement them. Left for a follow-up.

Subject: [PATCH 717/878] Report peak MemoryPool reservation per query in
 benchmarks (#23985)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Part of #22758. Doesn't close an issue.

## Rationale for this change

DataFusion's `MemoryPool` deliberately accounts for only the "large"
allocations that scale with input size; intermediate batches flowing
between operators are assumed to be small and left untracked. The
`MemoryPool` docs therefore advise reserving "some overhead (e.g. 10%)"
on top of the configured limit.

Nothing measures what that overhead actually is.
`MemoryPool::reserved()` is a live value that has usually fallen back to
zero by the time a query finishes, so the peak is never observed, and
benchmarks report peak RSS with nothing to compare it against.

This adds the missing number so the two can be compared. It is
measurement only — nothing enforces a relationship between the pool's
accounting and actual allocation, and no threshold or CI check is added.

This is complementary to the accounting work discussed in #22898. That
issue proposes changing *what* gets accounted (Arrow `claim()` / builder
`with_pool()`); because `ArrowMemoryPool` grows a DataFusion
`MemoryReservation` against the pool it wraps, `reserved()` is where
both models converge. This PR just makes the peak of that value
observable per query, so the effect of any such change — or of a
regression — is visible as a number rather than inferred.

Concretely, that means the peak follows the accounting instead of being
pinned to the current set of manually tracked consumers: nothing claims
buffers today, but if #22898 lands in either form, those bytes show up
here without further changes. There is a test covering that path.

## What changes are included in this PR?

- `PeakRecordingPool`, a delegating `MemoryPool` wrapper recording the
high-water mark of `reserved()`. Every method delegates; wrapping does
not change how memory is granted, limited, or reported.
- `CommonOpt::runtime_env_builder` installs it around the pool it
already builds, so every benchmark run with a memory limit reports the
peak without further changes.
- `BenchQuery` gains `pool_peak_bytes`, reset per case by
`start_new_case`, so each query gets its own reading rather than
inheriting the high-water mark of the queries before it.
- `print_memory_stats` prints the run-wide peak after the existing
mimalloc line, leaving `mem_profile`'s output parser untouched.

Everything is confined to the `benchmarks` crate. No trait changes.

`arrow-buffer/pool` and `datafusion-execution/arrow_buffer_pool` are
enabled as **dev-dependencies only**, so the benchmark binaries build
with exactly the features they had before — confirmed absent from `cargo
tree --no-dev-dependencies`.

## Are these changes tested?

Yes — 5 unit tests plus a doctest, and verified end-to-end with `dfbench
nlj --query 1 -i 2 --memory-limit 512M`, which emits `"pool_peak_bytes":
262528` per query.

One of those tests builds an `ArrowMemoryPool` over the recording pool
and asserts an Arrow-side reservation both raises the peak and releases
on drop, pinning the interaction described above.

The pre-existing `test_runtime_env_builder_reads_env_var` still asserts
`MemoryLimit::Finite(2G)` *through* the wrapper, which is direct
evidence the delegation is transparent.

The wrapper is installed only when a memory limit is configured, since
without one there is no pool to wrap. `pool_peak_bytes` is omitted from
the results JSON in that case, leaving output byte-identical to before
for runs without a limit — confirmed `compare.py` parses both old and
new files.

## Are there any user-facing changes?

No. Confined to the benchmarks crate; adds one optional field to the
benchmark results JSON.

+//! Records the peak [`MemoryPool`] reservation reached during a benchmark.
+//!
+//! DataFusion's [`MemoryPool`] deliberately accounts for only the "large"
+//! allocations that scale with input size; intermediate batches flowing between
+//! operators are assumed to be small and are left untracked. The [`MemoryPool`]
+//! documentation therefore advises reserving "some overhead (e.g. 10%)" on top
+//! of the configured limit.
+//!
+//! Nothing reports what that overhead actually is, because the peak reservation
+//! itself is never recorded — [`MemoryPool::reserved`] is a live value that has
+//! usually fallen back to zero by the time a query finishes. This module records
+//! the high-water mark so benchmarks can emit it alongside the peak RSS that
+//! [`print_memory_stats`] already prints, making the gap between the two
+//! measurable.
+//!
+//! This is measurement only: nothing here enforces a relationship between the
+//! two numbers.
+//!
+//! What lands in the peak is whatever the pool accounts for, so this follows
+//! the accounting rather than fixing it in place. Arrow-side reservations made
+//! through `ArrowMemoryPool` are included, because that adapter grows a
+//! DataFusion reservation against the pool it wraps; nothing claims buffers

+/// Wraps a [`MemoryPool`], recording the high-water mark of
+/// [`MemoryPool::reserved`] as reservations come and go.
+///
+/// Every method delegates to the wrapped pool, so wrapping does not change how
+/// memory is granted, limited, or reported. The one thing it does change is
+/// downcasting: `rt.memory_pool.downcast_ref::<FairSpillPool>()` now finds this
+/// wrapper instead of the pool it wraps. Nothing in the benchmarks relies on
+/// that, and [`Self::from_pool`] uses the same mechanism to find the recorder.
+///
+/// Both high-water marks are held per instance, so a benchmark that builds a
+/// fresh runtime per query gets a reading scoped to that query without any
+/// coordination.
+///
+/// # Example

+/// # use std::sync::Arc;
+/// # use datafusion::execution::memory_pool::{GreedyMemoryPool, MemoryConsumer, MemoryPool};

+/// let pool: Arc<dyn MemoryPool> = Arc::clone(&recording) as _;
+///
+/// let reservation = MemoryConsumer::new("example").register(&pool);
+/// reservation.try_grow(512)?;

+///
+/// // The pool is back to empty, but the high-water mark is retained.
+/// assert_eq!(pool.reserved(), 0);
+/// assert_eq!(recording.peak_reserved(), 512);

Subject: [PATCH 718/878] refactor(proto): move PartitionedFile / FileGroup
 serde into datafusion-datasource (#24006)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #23494. Precursor for #23497 / #23683 (`DataSource` /
`FileSource` proto hooks) and for #23752.

## Rationale for this change

The protobuf conversions for the file-scan leaf types —
`PartitionedFile`,
`FileGroup`, `FileRange` — live in `datafusion-proto` as `TryFromProto`
impls,
because that is historically the only crate that can name both sides
(the
DataFusion type and the prost message are both foreign to it, hence the
`TryFromProto` workaround trait in the first place).

That placement means any *other* crate that needs those conversions has
to
reimplement them. #23683 hits exactly this: a `FileSource` serializing
its own
scan config needs to encode file groups, so the first cut of that PR
grew a
private second copy of the `PartitionedFile` wire logic inside
`datafusion-datasource`, which can then drift from the central
serializer.
The same will be true of every source migrated under #23516–#23518.

Nothing about these conversions needs `datafusion-proto`: they are plain
data,
with `ScalarValue` / `Statistics` / `Schema` going through
`datafusion-proto-common`. They belong next to the types.

## What changes are included in this PR?

- New `datafusion_datasource::proto` module, behind a new `proto`
feature on
`datafusion-datasource` (off by default; `datafusion-proto` enables it):
  - `FileRange::try_to_proto` / `try_from_proto`
  - `PartitionedFile::try_to_proto` / `try_from_proto`
  - `FileGroup` <-> `protobuf::FileGroup`
- `datafusion-proto`'s `TryFromProto` impls for those types become
one-line
shims delegating to the new impls, so every existing caller keeps
working
  and the two sides cannot disagree.

### Why these are `TryFrom` and not `try_to_proto` hooks

`TryFromProto` exists because `datafusion-proto` owns neither side of
the
conversions it hosts: with both the DataFusion type and the prost
message
foreign to it, `impl TryFrom<protobuf::X> for X` is rejected by the
orphan
rule, so a local trait was the only way to say the same thing.

Moving a conversion into the crate that owns the DataFusion type removes
that
constraint, and `&T` is `#[fundamental]`, so both directions are
expressible
with the standard trait (checked, not assumed):

```rust
impl TryFrom<&protobuf::PartitionedFile> for PartitionedFile   // ok
impl TryFrom<&PartitionedFile> for protobuf::PartitionedFile   // ok
impl TryFrom<&[PartitionedFile]> for protobuf::FileGroup       // E0117
```

The last one is why `protobuf::FileGroup`'s *slice* conversion stays a
`TryFromProto` shim: `&[PartitionedFile]` is not a type this crate owns,
while
`&FileGroup` is. Callers inside DataFusion go through `FileGroup`.

So the rule this PR sets for the rest of #23494: **plain data uses
`TryFrom`;
anything needing an encode/decode context keeps the `try_to_proto(ctx)`
/
`try_from_proto(node, ctx)` hooks**, because the standard trait cannot
carry
that second argument. Usefully, none of the ~40
`TryFromProto`/`FromProto`
impls needs a context, and nothing that needs one was ever a
`TryFromProto`
impl — the two categories are already disjoint, so the shape now tells a
reader whether a conversion recurses.

### Why now

`FromProto` / `TryFromProto` were added in #21929, *after* the 54.0.0
release,
and 54.1.0 was cut before any of this landed — so they have never
shipped in a
release. Replacing them with the standard traits, and eventually
deleting them,
is a no-op for semver **today** and a major breaking change the moment
55.0.0
goes out. The same applies to the six inherent `try_to_proto` /
`try_from_proto`
methods this PR would otherwise have added: they are new, unreleased
API, so
choosing their final shape costs nothing right now.

The other reason to settle it here rather than in a follow-up: this is
the PR
that establishes the pattern for the data-source family (#23516-#23519
and
#23752 / #23781 are all queued behind it). Whichever shape merges first
is the
one they will copy.

Retiring the remaining ~34 impls is still its own follow-up. Two notes
for
whoever picks it up: the sink and format-option conversions can move
next to
their types the same way, but the ones for `datafusion-common`-owned
types
(`JoinType`, `NullEquality`, `TableReference`, `UnnestOptions`, ...)
cannot —
`datafusion-common` cannot depend on `datafusion-proto-models` (it is
underneath it via `datafusion-proto-common`). Their legal home is
`proto-models` itself, implementing on the local proto type, which is
already
how `proto-common` hosts the `ScalarValue` / `Statistics` conversions.

## Are these changes tested?

Yes.

- New unit tests in `datafusion_datasource::proto` covering the
`PartitionedFile` round trip (path, size, mtime, partition values,
range,
arrow schema, statistics), the `FileGroup` round trip, and the
invalid-path
  error.
- The existing `datafusion-proto` tests now exercise the delegating
shims, so
  they also pin the shims themselves.
- `datafusion-proto`, all features: 227 passed / 0 failed.
- `datafusion-datasource` with `proto`: 180 passed / 0 failed.
- Full workspace run: 10347 passed
(`cargo test --profile ci --workspace --lib --tests --features
avro,json,backtrace,extended_tests,recursive_protection,parquet_encryption`).
The only failures are 8 backtrace-symbolization tests in
`datafusion-common`,
a crate this PR does not touch and which sits below every crate it does;
they
  fail the same way on the base commit on macOS.
- `cargo fmt` and `ci/scripts/rust_clippy.sh` clean.

## Are there any user-facing changes?

The protobuf wire format is unchanged, and no existing API changes
shape.

Additive:

- New `proto` feature on `datafusion-datasource` (off by default).
- New `TryFrom` impls in both directions between `FileRange`,
  `PartitionedFile`, `FileGroup` and their protobuf messages, under that
feature. No new names are added to the crate's API surface: the trait is
  `core::convert::TryFrom`.

Note for reviewers: while writing the round-trip test I found that
`PartitionedFile` statistics do not round-trip cleanly on `main` — filed
as
#23998. This PR preserves that behavior exactly rather than changing
decode
semantics in a refactor; the test documents it.

Subject: [PATCH 719/878] perf: Replace SipHash with foldhash in
 `BoundedWindowAggExec` (#23984)

## Which issue does this PR close?

- Closes: #23983

## Rationale for this change

`PartitionWindowAggStates` and `PartitionBatches` were using IndexMap's
default SipHash hasher. Switching to foldhash yields a small but
measurable performance improvement.

Benchmark below. Note that the improvement is modest in part because
linear mode is very inefficient when there are many partitions (#23982);
I will send a PR for that separately.

Benchmarks:

- linear, 10,000 partitions: 216.7 ms -> 204.1 ms (~6%)
- linear, 100 partitions:     45.0 ms -> 45.4 ms (within drift)
- sorted, 10,000 partitions:  35.0 ms -> 34.8 ms (control)


## What changes are included in this PR?

* Add new benchmark
* Switch from using SipHash to foldhash

## Are these changes tested?

Yes, covered by existing tests.

## Are there any user-facing changes?

No functional change at all.

+//! Benchmark for `BoundedWindowAggExec` with many partitions.

+//! partition on every batch, so its performance is sensitive to both the
+//! number of live partitions and the cost of hashing the keys. `Linear`

+//! columns) keeps every partition live until the input is exhausted and is
+//! the stress case; `Sorted` mode prunes finished partitions eagerly and
+//! serves as the control.

Subject: [PATCH 720/878] chore: refactor `MaterializingSortMergeJoinStream`
 into generators and simplify code to be textbook like as possible (#23976)

## Which issue does this PR close?

Part of:
- https://github.com/apache/datafusion/issues/23974

## Rationale for this change

Simplify the code and make code similar to textbook so it is easier to
read

## What changes are included in this PR?
Changed to async generators + simplified to be similar to textbook

Most of the code was written by Claude Fable 5 since it was just too
large to comprehend in head

## Are these changes tested?
existing tests + a little more tests to verify we are not counting the
childs in the join time

## Are there any user-facing changes?
The join_time now includes the time to read from the async spill stream
between pending which is arguable more correct since this time is part
of the operator, although long waits between pending calls will be
counted in the op `join_time` while the alternative is not counting the
read from file and decoding...

Subject: [PATCH 721/878] refactor(proto): put Partitioning / sort-expression
 serde on the types (#24003)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #23494 (the `try_to_proto` / `try_from_proto` migration).
Precursor for #23497 / #23683 / #23498 and for the remaining per-plan
migrations that need to encode an output partitioning or an ordering.

## Rationale for this change

`Partitioning`'s protobuf conversion currently exists in three places:

- inline in `RepartitionExec::try_to_proto`,
- inline in `RepartitionExec::try_from_proto`,
- in `datafusion-proto`'s `serialize_partitioning` /
`parse_protobuf_partitioning`.

Every plan or data source migrated to the hooks that has an output
partitioning has so far copied it again — #23683 is about to add a
fourth
copy for `FileScanConfig`.

The flat `PhysicalSortExprNode` encoding is the same story, one level
down and
more widespread: `AggregateExec`'s ordering requirement,
`SymmetricHashJoinExec`'s
left and right sort expressions, the window expressions, and range
partitioning
each hand-roll the same `map` / `collect` over
`PhysicalSortExprNode { expr, asc, nulls_first }`, on both the encode
and the
decode side. #23683 (`output_ordering`) and #23752 / #23781 (the sinks'
required
ordering) are about to add two more.

There is no reason for this logic to live in the callers: it converts a
`Partitioning` (and the `PhysicalSortExpr`s and `ScalarValue`s inside
it), and
needs nothing from the plan level beyond the ability to encode a child
expression.

## What changes are included in this PR?

Put the single copy next to the types that own it, taking the
expression-level
context (`datafusion-physical-expr` and `-common` already carry the
`proto`
feature):

- `PhysicalSortExpr::try_to_proto` / `try_from_proto`
(`physical-expr-common`)
- `sort_exprs_try_to_proto` / `sort_exprs_try_from_proto`
(`physical-expr-common`),
  the sequence form every caller actually needs
- `Partitioning::try_to_proto` / `try_from_proto` (`physical-expr`)

So plan hooks can reach them, `ExecutionPlanEncodeCtx` /
`ExecutionPlanDecodeCtx`
now back the expression-level contexts (`PhysicalExprEncode` /
`PhysicalExprDecode`) and hand one out via `expr_ctx()`. That bridge is
useful
beyond partitioning: from here on any plan hook can pass its ctx
straight to an
expression-level conversion, which is the shape the rest of the
migration wants.

The sequence encoder is generic over `Borrow<PhysicalSortExpr>`, so one
function
serves a `LexOrdering`, a `&[PhysicalSortExpr]`, and a `LexRequirement`
mapped
through `PhysicalSortExpr::from`. The decoder returns the expressions
rather
than a `LexOrdering`, because callers disagree on what an empty list
means: "no
ordering declared" for a scan, an error for an operator that requires
one.

Routed through the new methods:

- `RepartitionExec` and `datafusion-proto`'s central serializer, which
also
  retires `serialize_range_partitioning`, `serialize_range_split_point`,
`parse_protobuf_range_partitioning` and
`parse_protobuf_range_split_point`,
- `AggregateExec`'s ordering requirement, `SymmetricHashJoinExec`'s
left/right
  sort expressions, and the window expressions — encode and decode each.

Net: −380 / +458 lines with the new tests included; production code
shrinks. The
next operator that needs partitioning or ordering serde writes one line
instead
of sixty.

## Are these changes tested?

Yes.

- New unit tests for the sequence helpers (option and order fidelity,
owned
`LexRequirement` input, encode-error propagation, missing inner
expression),
  using the existing `proto_test_util` stubs.
- The existing round-trip suites cover the rest, and now exercise the
shared
  path: all four partitioning variants (`datafusion-proto`'s
  `roundtrip_physical_plan` tests exercise the central serializer,
`RepartitionExec`'s own hook tests exercise the plan path), plus
aggregate
`ORDER BY`, window `ORDER BY` and symmetric-hash-join sort expressions
for the
  ordering helpers. `datafusion-proto`: 209 passed / 0 failed.
- Lib suites for the three changed crates: 1613 + 1651 + 80 passed / 0
failed.
- Full workspace run: 10344 passed
(`cargo test --profile ci --workspace --lib --tests --features
avro,json,backtrace,extended_tests,recursive_protection,parquet_encryption`).
The only failures are 8 backtrace-symbolization tests in
`datafusion-common`
and 4 `datafusion-cli` tests that hard-code a repo-relative
`parquet-testing/`
path; both are artifacts of running from a linked worktree on macOS, in
crates
this PR does not touch, and the `datafusion-cli` four pass once that
path
  resolves.
- `cargo fmt` and `ci/scripts/rust_clippy.sh` clean.

## Are there any user-facing changes?

The protobuf wire format is unchanged.

Additive API:

- `Partitioning::try_to_proto` / `try_from_proto`,
`PhysicalSortExpr::try_to_proto` /
`try_from_proto`, `sort_exprs_try_to_proto` /
`sort_exprs_try_from_proto`
  (feature `proto`).
- `ExecutionPlanEncodeCtx::expr_ctx()` /
`ExecutionPlanDecodeCtx::expr_ctx(schema)`.

Two behavior differences, both in error paths:

- Out-of-range partition counts now return an error instead of wrapping
  (`as usize`) or panicking (`try_into().unwrap()` in
  `parse_protobuf_hash_partitioning`).
- A missing sort-expression child now reports which field is missing
  (`PhysicalSortExpr is missing required field 'expr'`) instead of
`Unexpected empty physical expression`, and the same message now
replaces the
three bespoke ones in `AggregateExec`, `SymmetricHashJoinExec` and the
window
  expressions.

Four private helpers in `datafusion-proto` are removed
(`serialize_range_partitioning`, `serialize_range_split_point`,
`parse_protobuf_range_partitioning`,
`parse_protobuf_range_split_point`); the
public `serialize_partitioning` / `parse_protobuf_partitioning` keep
their
signatures and behavior.

Subject: [PATCH 722/878] fix: keep a CoalescePartitionsExec required by a
 SinglePartition child (#23948)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

## Which issue does this PR close?

- None filed; happy to open one if preferred.

## Rationale for this change

A valid query can be planned into a physical plan that `SanityCheckPlan`
then rejects:

```
SanityCheckPlan
caused by
Error during planning: Plan: ["HashJoinExec: mode=CollectLeft, join_type=Left, on=[(id@0, id@0)], projection=[id@0]",
  "  DataSourceExec: file_groups={4 groups: [...]}, projection=[id], file_type=parquet",
  "  RepartitionExec: partitioning=RoundRobinBatch(8), input_partitions=1",
  "    CoalescePartitionsExec",
  "      ProjectionExec: expr=[first_value(t.id) ORDER BY [...]@1 as id]",
  "        AggregateExec: mode=FinalPartitioned, gby=[id@0 as id], aggr=[first_value(t.id) ORDER BY [...]]",
  "          RepartitionExec: partitioning=Hash([id@0], 8), input_partitions=4",
  "            AggregateExec: mode=Partial, gby=[id@1 as id], aggr=[first_value(t.id) ORDER BY [...]]",
  "              DataSourceExec: file_groups={4 groups: [...]}, projection=[ts, id], file_type=parquet"]
does not satisfy distribution requirements: SinglePartition. Child-0 output partitioning: UnknownPartitioning(4)
```

The `HashJoinExec` is in `CollectLeft` mode, which requires
`Distribution::SinglePartition` on its build (left) child, but child 0
is a bare 4-partition `DataSourceExec` with no `CoalescePartitionsExec`
above it.

Self-contained reproducer with `datafusion-cli` (the four `COPY`
statements are what make the scan multi-partition):

```sql
set datafusion.execution.target_partitions = 8;
set datafusion.optimizer.repartition_file_scans = false;

create table src (id int, ts int) as values (1, 10), (2, 20), (3, 30);

copy (select * from src) to 'data/0.parquet' stored as parquet;
copy (select * from src) to 'data/1.parquet' stored as parquet;
copy (select * from src) to 'data/2.parquet' stored as parquet;
copy (select * from src) to 'data/3.parquet' stored as parquet;

create external table t stored as parquet location 'data/';

select a.id
from t a
left join (select distinct on (id) id, ts from t order by id, ts) f on a.id = f.id
order by a.id;
```

Setting `datafusion.optimizer.repartition_sorts = false` makes it plan
fine, which points at the sort-parallelization phase.

`EnsureRequirements` does insert the coalesce for the `SinglePartition`
requirement (`enforce_distribution.rs`, `Distribution::SinglePartition
=> add_merge_on_top(...)`). Its own phase 3a (`parallelize_sorts`) then
takes it back out: `remove_bottleneck_in_subplan` removes a
`CoalescePartitionsExec` found at `children[0]` positionally, without
consulting the parent's distribution requirement for that child.

That parent is reached because `update_coalesce_ctx_children` marks a
node as connected when *any* child qualifies. It correctly excludes a
`SinglePartition`-requiring child from *setting* the flag, but the
join's other child (`UnspecifiedDistribution`, connected to a coalesce
below) sets it, so the traversal descends into the join and rewrites
child 0 anyway. Nothing re-enforces distribution afterwards, so
`SanityCheckPlan` is the first thing to notice. Note the surviving
`CoalescePartitionsExec` on the probe side in the plan above: it is what
propagated the flag, and it is untouched because the `if` returns
without recursing into child 1.

The sibling helper on the phase 2b path already does consult the
requirement (`update_child_to_remove_unnecessary_sort` /
`remove_corresponding_sort_from_sub_plan` re-add a merge using the
per-child `child_distribution(child_idx)`); only this path is missing
it.

The same failure shows up with a build child that is already
hash-partitioned on the join key (`Child-0 output partitioning:
Hash([k@0], 8)`), which is what a `JoinSelection` input swap leaves
behind — a `CollectLeft` join reported as `join_type=Right` with an
embedded projection.

## What changes are included in this PR?

`remove_bottleneck_in_subplan` now checks the parent's per-child
distribution requirement before removing a coalesce, both for
`children[0]` and when recursing into the other children.

The node `parallelize_sorts` is itself rewriting (the root of the call)
is exempt, since the caller drops that node and rebuilds the sort
cascade around the result — that is the rule's intended transformation,
and gating it too would disable sort parallelization below a global
sort. This is threaded through as an `is_root` flag on a private `_impl`
function; the public entry point keeps its signature.

## Are these changes tested?

Yes, at two levels:

- An end-to-end sqllogictest in
`datafusion/sqllogictest/test_files/joins.slt` reproducing it from SQL
(the reproducer above, with the data written by `COPY` inside the test).
On `main` it fails with exactly the distribution error above.
- Two tests in
`datafusion/core/tests/physical_optimizer/ensure_requirements.rs`
covering both shapes of the build child (`UnknownPartitioning(n)` and
`Hash([k], n)`), running the full `EnsureRequirements` rule and then
`SanityCheckPlan` via the existing `optimize_and_sanity_check` helper,
plus the idempotency check.

`cargo test -p datafusion-physical-optimizer`, `cargo test -p datafusion
--test core_integration -- physical_optimizer` (530 tests) and the full
`sqllogictest` suite (498 files) pass.

## Are there any user-facing changes?

No API changes. Plans that were previously rejected by `SanityCheckPlan`
now plan and execute; a coalesce that is genuinely required is retained
where it was previously (incorrectly) removed.

Subject: [PATCH 723/878] fix: TopK aggregation drops groups whose MIN/MAX
 value is NULL (#23684)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23440
- Closes #22190

## Rationale for this change

When `TopKAggregation` pushes a `LIMIT` into a MIN/MAX aggregate, a
group whose aggregate inputs are all NULL can disappear instead of being
returned with a NULL aggregate value.

The stream previously skipped NULL aggregate inputs without registering
the group. This is correct for an individual MIN/MAX input, but not for
a group whose inputs are all NULL.

There is also an important correctness boundary: nullable MIN/MAX with
`NULLS FIRST` is not monotonic for a bounded aggregation. A group can
start at NULL, later become non-NULL, and thereby move to a worse rank.
Keeping only `limit` NULL candidates can therefore discard a group that
belongs in the final result.

## What changes are included?

- Track up to `limit` all-NULL candidates alongside valued TopK groups
and emit them for the parent sort to rank and truncate.
- Correctly convert a tracked NULL group when its first value arrives,
or unregister it when that value cannot enter the valued TopK.
- Skip TopK pushdown for nullable MIN/MAX with `NULLS FIRST`; regular
aggregation is used for exact results. TopK remains enabled for `NULLS
LAST`, non-nullable MIN/MAX inputs, and GROUP BY-only/DISTINCT queries.
- Replace the single reusable hash-table slot with a free-slot stack. A
NULL-to-value conversion can free both the NULL registration and an
evicted valued group, so retaining only one slot caused unbounded
backing-store growth under repeated conversions.
- Select NULL-aware insertion once per batch, keeping NULL bookkeeping
off the common no-NULL per-row hot path.
- Add regression coverage for all-NULL groups, mixed NULL/value batches,
bounded NULL candidate backfill, evicted groups, hash-table slot reuse,
and optimizer plan selection.

## Are these changes tested?

Yes. The following passed on the final commit:

- `cargo fmt --all -- --check`
- `cargo clippy --all-targets --all-features -- -D warnings`
- TopK physical-plan unit tests (33 tests)
- `aggregates_topk.slt` and affected `group_by.slt` tests
- The repository's extended workspace command with
`avro,json,backtrace,extended_tests,recursive_protection,parquet_encryption`,
including all 495 sqllogic files and extended/fuzz suites

## Performance

The `topk_aggregate` 10-million-row time-series benchmark exposed an
initial ~5.5% regression from checking NULL state on every row. Moving
NULL handling to a batch-selected slow path removed the measurable
regression.

Final 30-sample 95% intervals on the same machine and settings:

- `main`: 25.630–26.436 ms
- this PR: 25.151–27.061 ms

## Are there any user-facing changes?

Queries that previously dropped all-NULL groups under `ORDER BY
<min/max> ... LIMIT` now return correct SQL results. Nullable MIN/MAX
queries using `NULLS FIRST` may use regular aggregation rather than the
bounded TopK optimization to guarantee correctness. There are no API or
configuration changes.

Subject: [PATCH 724/878] feat:  add GroupColumn support for Duration in
 multi-column GROUP BY (#23783)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #22715.

## Rationale for this change

`multi_group_by::group_column_supported_type` gates which GROUP BY
columns may
use the column-wise `GroupValuesColumn` fast path, and the gate is
all-or-nothing: a single unsupported column forces the **entire**
grouping onto
the byte-encoded `GroupValuesRows` fallback, even when every other key
column
would have qualified. A `Duration` key triggers exactly that today, so
an
otherwise-qualifying multi-column `GROUP BY` pays the row-encoding tax
because of
one column.

`Duration` shares the `i64` native representation already used by
`Timestamp`,
so supporting it is a pure slot-in of the existing
`PrimitiveGroupValueBuilder` —
no new builder type and no new comparison/hash logic.

## What changes are included in this PR?

- Accept `Duration(_)` in `group_column_supported_type` (all four
`TimeUnit`s are
  valid Arrow types, unlike the restricted `Time32`/`Time64` set).
- Dispatch the four `Duration*Type` units in `make_group_column`.
- Extend the `group_column_supported_type` ↔ `make_group_column`
consistency fuzz
  with all four Duration units.
- Add a `(Duration, Int32)` group-count benchmark to
`benches/multi_group_by.rs`.

## Are these changes tested?

Yes.
- New unit test `test_group_values_column_duration`: a
`(Duration(Microsecond), Int64)` key stays on the `GroupValuesColumn`
path,
  dedups on the composite key (including the `(null, null)` pair), and
round-trips with the `Duration` output type preserved (not the bare
`i64`).
- The consistency fuzz now asserts every `Duration` unit routes through
the
  dispatcher.
- New single- and multi-column `Duration` `GROUP BY` coverage in
`group_by.slt`.

## Are there any user-facing changes?

No API changes. `GROUP BY` queries with a `Duration` key now use the
column-wise
fast path instead of the row-encoded fallback; results are unchanged.

Subject: [PATCH 725/878] refactor: move planning APIs to session crate
 (#23842)

## Which issue does this PR close?

- Addresses a portion of
https://github.com/apache/datafusion/issues/23678
- Follow on to https://github.com/apache/datafusion/pull/23703

## Rationale for this change

This PR unlocks using a query planner across the FFI boundary.

## What changes are included in this PR?

Moves these traits to the `datafusion-session` crate:

- `QueryPlanner`
- `PhysicalPlanner`
- `ExtensionPlanner`
- `PhysicalOptimizerRule`
- `PhysicalOptimizerContext`

Additionally changed the method signatures from taking `&SessionState`
to `&dyn Session`.

Adds these methods on `Session` trait:

- `fn query_planner(&self) -> Arc<dyn QueryPlanner + Send + Sync>`
- `fn optimize(&self, plan: &LogicalPlan) -> Result<LogicalPlan>`
- `fn physical_optimizers(&self) -> &[Arc<dyn PhysicalOptimizerRule +
Send + Sync>]`
- `fn statistics_registry(&self) -> Option<&StatisticsRegistry>`

## Are these changes tested?

Unit tests are added for the new methods.

## Are there any user-facing changes?

Yes, users must implement new methods for `query_planner` for their
custom `Session`. This is not expected to impact many users, since it is
most common to use the existing `SessionState`.

+`Session` gains a `query_planner` method alongside `optimize`,
+`physical_optimizers`, and `statistics_registry`. All four have default
+implementations, so existing `Session` implementations that do not perform
+physical planning require no changes: `query_planner` defaults to the new

+
+A custom session that drives planning through `DefaultQueryPlanner` or

+optimization behavior; the defaults will otherwise produce unoptimized plans or
+fail to plan at all. The simplest approach is to delegate to a `SessionState`:

+```rust

+use datafusion_session::{PhysicalOptimizerRule, QueryPlanner};
+
+fn query_planner(&self) -> Arc<dyn QueryPlanner + Send + Sync> {

+
+`ForeignSession::create_physical_plan` continues to run the complete planning
+pipeline in the library that owns the session. `ForeignSession::query_planner`
+returns `UnsupportedQueryPlanner` until the query planner FFI interface is
+available. FFI wrappers for the individual planner and optimizer interfaces are

Subject: [PATCH 726/878] bench: use seedable rng for reproducibility (#23653)

## Which issue does this PR close?

- Closes #23652.

## Rationale for this change

It's a follow-up PR to the [noisy
benchmark](https://github.com/apache/datafusion/pull/23586#issuecomment-4984137575)
issue. Let's use a seeded StdRng everywhere in benchmarks to make
results more predictable. It is widely used now.

## What changes are included in this PR?

Switch from a randomly initialised generator to a seeded generator

## Are these changes tested?

A recetnt `cargo bench --bench pad` runs fine

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

Subject: [PATCH 727/878] test: Fix data_pagesize_limit extraction in parquet
 writer props roundtrip test (#23664)

## Which issue does this PR close?

N/A

## Rationale for this change

In the test helper `session_config_from_writer_props`,
`data_pagesize_limit` is extracted from
`props.dictionary_page_size_limit()` instead of
`props.data_page_size_limit()`. The bug is masked because
`parquet_options_with_non_defaults` sets both limits to the same value
(42), so the roundtrip test cannot catch a mixed-up mapping between
these two options.

## What changes are included in this PR?

- Extract `data_pagesize_limit` from `props.data_page_size_limit()`.
- Use distinct values for `data_pagesize_limit` (42) and
`dictionary_page_size_limit` (43) in the test options so the roundtrip
test can detect such mix-ups.

## Are these changes tested?

Yes, covered by the existing `table_parquet_opts_to_writer_props`
roundtrip test. Verified that reverting the extraction fix now makes the
test fail.

## Are there any user-facing changes?

No, test-only change.

Subject: [PATCH 728/878] bench: extend BoundedWindowAggExec many-partitions
 benchmark (#24032)

## Which issue does this PR close?

- Related to #23982

## Rationale for this change

The existing cases measure COUNT over a RANGE frame on round-robin
partition keys: Linear mode over 100 and 10000 partitions, plus
Sorted-mode over the 10000 partitions. Each batch contains rows for most
of the partition set, and every case exercises a single window
expression over one frame type.

Add Linear-mode shapes that stress the operator's per-partition state
differently:

- linear, 32768 partitions, sparse: each batch introduces a block of
2048 previously unseen keys (4 rows each) and never revisits them, so
the live partition set grows for the whole run while each batch touches
only its newest partitions.
- linear, 10000 partitions, ROWS frame, round-robin partition layout.
- linear, 10000 partitions, two window expressions, round-robin
partition layout.

## What changes are included in this PR?

See above.

## Are these changes tested?

Tested manually.

## Are there any user-facing changes?

No.

+//! - `linear rows N partitions`: the dense layout with a ROWS frame, whose

+//!   arrive.
+//! - `linear multi N partitions`: two window expressions over the dense
+//!   layout, doubling the per-partition evaluation sweeps.
+//! - `sorted N partitions`: control; input sorted by partition key, so
+//!   finished partitions are pruned eagerly and the state maps stay small.

Subject: [PATCH 729/878] feat: add GroupColumn support for Float16 in
 multi-column GROUP BY (#23785)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #22715.

## Rationale for this change

`multi_group_by::group_column_supported_type` gates which GROUP BY
columns may
use the column-wise `GroupValuesColumn` fast path, and the gate is
all-or-nothing: a single unsupported column forces the **entire**
grouping onto
the byte-encoded `GroupValuesRows` fallback, even when every other key
column
would have qualified. A `Float16` key triggers exactly that today.

`Float16` reuses the existing `PrimitiveGroupValueBuilder` with no new
builder
type: its native `half::f16` already implements the `HashValue`
canonicalization (`hash_float!(f16, f32, f64)`), so `-0.0`/`+0.0`
folding and
`NaN` grouping match `Float32`/`Float64` with no extra handling.

## What changes are included in this PR?

- Accept `Float16` in `group_column_supported_type` and dispatch it in
  `make_group_column`.
- Move `Float16` from the rejected to the accepted set in the
`group_column_supported_type` ↔ `make_group_column` consistency fuzz,
and
repoint the two tests that used `Float16` as their stock "unsupported"
example
to a permanently-invalid unit combo (`Time64(Second)`), so they stay
stable as
sibling primitive builders (Decimal256, Interval, …) land independently.
- Add a `(Float16, Int32)` group-count benchmark to
`benches/multi_group_by.rs`
  (capped below f16's ~63.5k distinct finite values).

## Are these changes tested?

Yes.
- New unit test `test_group_values_column_float16`: a `(Float16, Int32)`
key
  stays on the `GroupValuesColumn` path, dedups including nulls, folds
`-0.0`/`+0.0` into one group (stored as `+0.0`), groups equal `NaN`s,
keeps
`(0.0, 4)` distinct from `(±0.0, 3)` via the `Int32` key, and
round-trips
  with the `Float16` output type preserved.
- The consistency fuzz now asserts `Float16` routes through the
dispatcher.
- New single- and multi-column `Float16` `GROUP BY` coverage in
`group_by.slt`.

## Are there any user-facing changes?

No API changes. `GROUP BY` queries with a `Float16` key now use the
column-wise
fast path instead of the row-encoded fallback; results are unchanged.

Subject: [PATCH 730/878] fix(sql): preserve source qualifiers in CTAS with
 explicit schema (#23879)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23878.

## Rationale for this change

CTAS with an explicit schema fails when qualified source columns have
the same name because their qualifiers are not preserved.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Preserve source column qualifiers in the CTAS cast projection.
- Add a SQL logic test for this case.

## Are these changes tested?

Yes.

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

This is a bug fix with no public API changes.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 732/878] test: add IN list slt coverage for temporal,
 Decimal128 and Interval types (#23875)

## Which issue does this PR close?

- Part of #23307.

## Rationale for this change

IN lists over temporal, `Decimal128` and `Interval` columns had no SQL
level coverage at all, and the specializations being added in #23014
route those types onto new code paths.

## What changes are included in this PR?

Adds `in_list.slt` coverage for `Date32`, `Date64`, `Time32(Second)`,
`Time64(Nanosecond)`, `Timestamp(Nanosecond, None)`, `Timestamp(Second,
"UTC")`, `Duration(Second)`, `Decimal128` and `Interval(MonthDayNano)`

## Are these changes tested?

Subject: [PATCH 733/878] feat: Add support for `explode_outer` function for
 arrays (#22100)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #19053.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

DataFusion's 'unnest' had no way to express Spark 'explode_outer'
semantics, empty input lists were silently dropped, even with
'preserve_nulls' = true.


## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Adds a third unnest behavior that produces a `NULL` row for empty input
lists, by replacing `UnnestOptions.preserve_nulls: bool` with a
`NullHandling { Drop, Preserve, PreserveAndExpandEmpty }` enum. The
`with_preserve_nulls(bool)` builder is kept as a backward-compat shim.


## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes, new unit test for the empty-list case, extended longest-length and
DataFrame `unnest_column_nulls` tests, and existing proto round-trip
coverage.


## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

The `preserve_nulls` field on `UnnestOptions` is renamed to
`null_handling`. The `with_preserve_nulls(bool)` builder is preserved,
so most callers are unaffected. Add the `api change` label for the field
rename.

+### `unnest_outer`
+
+`unnest_outer(col)` is the outer-unnest peer to `UNNEST(col)`. The two differ
+only in how `NULL` and empty input lists are handled:
+
+| Form                | `NULL` input list | Empty input list |
+| ------------------- | ----------------- | ---------------- |
+| `UNNEST(col)`       | dropped           | dropped          |
+| `unnest_outer(col)` | one `NULL` row    | one `NULL` row   |
+
+```sql
+SELECT id, unnest_outer(tags) AS tag FROM rows;
+```
+
+An input row with an empty `tags` array or `NULL` `tags` produces one output
+row whose `tag` is `NULL`, instead of being dropped. This is analogous to the
+outer variant offered by other engines (Spark `explode_outer`, Hive `EXPLODE OUTER`, Snowflake `FLATTEN(OUTER => true)`).
+
+`unnest_outer` cannot be mixed with `unnest` in the same `SELECT` — the
+unnest plan node carries a single null-handling mode for all its output
+columns, so a mix would be ambiguous. The planner returns an error in that
+case.

Subject: [PATCH 734/878] fix: reject nested arrays in array_distance (#23995)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
See reproducer in `datafusion-cli`, now `array_distance()` allows nested
list as input, and it will use the 1st inner array to compute the
distance.
```
> select array_distance([[1, 2], [100, 100]], [[1, 4], [0, 0]]);

```

This look like an invalid input, this PR reject nested array in this
function

## What changes are included in this PR?

At function planning, reject `array_distance` with nested array input
args

## Are these changes tested?

Yes, slt (plus some extra tests that I found that has not been covered
in `codecov`)
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

+### `array_distance` scalar function now rejects multidimensional arrays
+
+`array_distance` only supports one-dimensional arrays. Previously, when given
+multidimensional arrays, it computed the distance using only the first
+subarray and ignored the remaining subarrays. For example:
+
+```sql
+SELECT array_distance(
+    [[1, 2], [100, 100]],
+    [[1, 4], [0, 0]]
+);
+```
+
+Previously, this query returned `2.0`, the distance between `[1, 2]` and
+`[1, 4]`. It now returns a planning error stating that `array_distance` only
+supports one-dimensional arrays.

Subject: [PATCH 735/878] fix: Improve error message for metadata conflict in
 schema (#23952)

## Which issue does this PR close?

- Closes https://github.com/apache/datafusion/issues/23461

## Rationale for this change

Based on the discussion with @2010YOUY01 in
https://github.com/apache/datafusion/issues/23461 this pr improves the
error message when there is a metadata conflict when schemas get merged.
It also reverts https://github.com/apache/datafusion/pull/23605, so
`CrossJoinExec` has again the original behavior.


```sql
select * from larger_table cross join smaller_table;

DataFusion error: PhysicalOptimizer rule 'join_selection' failed. Schema mismatch caused by
Internal error: Schema metadata mismatch: Expected original metadata: {"metadata_key": "right"}, got metadata: {"metadata_key": "left"}
```


## What changes are included in this PR?

- Revert https://github.com/apache/datafusion/pull/23605 the behavior
change for `CrossJoinExec`
- Improve error messages for schema validation in `physical_planner.rs`
- Data creation in `test_context.rs`
- Reproduction in `metadata.slt`


## Are these changes tested?

Yes

## Are there any user-facing changes?

Yes, error message improved when the schema metadata has conflicting
keys using a cross-join.

Subject: [PATCH 736/878] fix: rows_to_array cleanup for expecting single field
 (#24040)

## Which issue does this PR close?

- Closes #23996

## Rationale for this change

Making the `rows_to_array` method in`RowsGroupColumn` behavior of
expecting a singular field explicit, as before it used a generic vector
operation of `swap_remove(0)` and a `debug_assert_eq!` for ensuring that
there was only a single field extracted

## What changes are included in this PR?

Changed the `debug_assert_eq!` to the non-debug macro with a clear error
message & changing the `swap_remove(0)` to a `pop` with `unwrap` now
that we are guaranteeing the invariant

## Are these changes tested?

Yes

## Are there any user-facing changes?

No

Subject: [PATCH 739/878] minor(fix): correct to_date results for formatted
 pre-epoch datetimes (#24049)

## Which issue does this PR close?

- Closes N\A but I can open an issue

 ## Rationale for this change

Formatted `to_date` inputs are parsed as milliseconds since the Unix
epoch and then converted to `Date32` days. Integer division truncates
toward zero, so negative sub-day timestamps are incorrectly mapped to
day `0` instead of day `-1`.

 ```sql
 -- DataFusion before this change
 SELECT to_date('1969-12-31 12:00:00', '%Y-%m-%d %H:%M:%S');
 -- 1970-01-01

 -- PostgreSQL
 SELECT to_date('1969-12-31 12:00:00', 'YYYY-MM-DD HH24:MI:SS');
 -- 1969-12-31

 -- DuckDB
SELECT CAST(strptime('1969-12-31 12:00:00', '%Y-%m-%d %H:%M:%S') AS
DATE);
 -- 1969-12-31
```

## What changes are included in this PR?

Use Euclidean division when converting formatted timestamp milliseconds to days, preserving the correct date for timestamps before the Unix epoch.

## Are these changes tested?
Yes new slt test for this case.

## Are there any user-facing changes?

No API changes. Formatted pre-epoch datetimes now return the correct date.

Subject: [PATCH 740/878] minor(test): strengthen sort-merge join spilling
 coverage (#23988)

## Which issue does this PR close?
 - Part of #13431

 ## Rationale for this change
Contuining the work after #23947. Now `SortMergeJoinExec` supports
spilling under memory pressure, but existing tests do not consistently
assert that spilling occurs.

 ## What changes are included in this PR?
Adds spill fuzz coverage, constrained-memory stress tests for
materializing joins, and process-isolated memory-limit validation.

 ## Are these changes tested?
 test only change and it can be tested via:

```

cargo test -p datafusion --test fuzz --features extended_tests spill
cargo test -p datafusion --test core_integration --features extended_tests smj_

```

 ## Are there any user-facing changes?
 no test only change

Subject: [PATCH 741/878] refactor(hash-aggr): Support spilling for single mode
 aggregation (#23965)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

Part of https://github.com/apache/datafusion/issues/22710

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
This PR implements larger-than-memory execution for single mode
aggregation.

See top comments at `single_stream.rs` for the high-level idea. The key
implementations are in the same file.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Existing tests.
- [x] todo for myself: double check the codecov
update: I've checked codecov, line coverage for spilling is good,
uncovered lines are all unreachable/internal errors.

## Are there any user-facing changes?
No
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Codecov reports low test coverage for this function, so this PR adds
more SLT tests for it.

The tests were AI-generated, and I manually verified that the results
are correct.

See `Codecov` bot comment -> `☔ View full report in Codecov by Harness`
-> `Indirect Changes` for the updated test coverage.

Subject: [PATCH 743/878] perf: preserve dictionary encoding for
 `character_length`, `initcap`, and `reverse` (#23930)

-->

- Follow-up to #22905
- Related to #19458 and #20935

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

Previously, coercion materialized dictionary-encoded inputs for
`character_length`, `initcap`, and `reverse`. This lost the encoding and
evaluated the function for every row instead of once per dictionary
value entry.

This PR extends dictionary preservation to these functions.

`character_length` and `reverse` now use `Coercible` signatures to
explicitly model string inputs and binary-to-string coercion while
preserving dictionary encoding.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Preserve dictionary encoding for `character_length`, `initcap`, and
`reverse`.
- Evaluate only dictionary values while reusing the original keys.
- Migrate `character_length` and `reverse` from `Uniform` to
`Coercible`.
- Add tests and benchmarks.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes, covered by SQL logic tests.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Yes. These functions now preserve dictionary encoding in their output.

`character_length` and `reverse` now accept logical string and binary
inputs instead of implicitly converting unrelated types to strings.

Subject: [PATCH 744/878] feat: switch VirtualTable producer to use expressions
 field instead of deprecated values (#23672)

## Which issue does this PR close?

- Closes #23608

## Rationale for this change
Since the VirtualTables.values field has been deprecated and is soon to
be removed in the next substrait update, we should make sure to delete
all instances of it to prevent the presence of dead code.

This PR switches the producer to generate VirtualTables using only the
expressions field. A later PR will be released to fully remove all
instances of the `values` field. The reason removal will be separate is
because we want to give users a chance to update any stored plans, and
then remove values.

The consumer also needed an update, because since the producer only
emits expressions, a new gap was introduced where expressions never uses
named_struct.names to rename nested fields (structs/lists) the way the
values/literal path does. So for flat/scalar columns, expressions would
work fine, but for struct/list-typed columns, the consumer would
silently drop original nested field names and fall back to positional
defaults.

## What changes are included in this PR?

Producer now emits VirtualTable.expressions for Values and
EmptyRelation. Converted 17 direct virtualTable.values entries across 10
JSON test plans to virtualTable.expressions. Consumer now adds support
for struct field-name preservation when reading from only expressions.

## Are these changes tested?
Yes they are. Tests ran:
```
cargo check -p datafusion-substrait
cargo test -p datafusion-substrait -- test substrait_integration roundtrip_values
cargo test -p datafusion-substrait -- test substrait_integration consumer_integration
cargo test -p datafusion-substrait -- test substrait_integration builtin_expr_semantics_tests
cargo test -p datafusion-substrait -- test substrait_integration non_nullable_lists
```
jq validation for JSON fixtures


## Are there any user-facing changes?
No.

Subject: [PATCH 745/878] feat: add GroupColumn support for Interval in
 multi-column GROUP BY (#23786)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #22715.

## Rationale for this change

`multi_group_by::group_column_supported_type` gates which GROUP BY
columns may
use the column-wise `GroupValuesColumn` fast path, and the gate is
all-or-nothing: a single unsupported column forces the **entire**
grouping onto
the byte-encoded `GroupValuesRows` fallback, even when every other key
column
would have qualified. An `Interval` key triggers exactly that today.

All three `Interval` units reuse the existing
`PrimitiveGroupValueBuilder` with
no new builder type and no new `HashValue` impl — the `i32` /
`IntervalDayTime`
/ `IntervalMonthDayNano` natives already implement it.

## What changes are included in this PR?

- Dispatch the three `Interval*Type` units in `make_group_column`.
`IntervalUnit`
has exactly three variants, so the match is exhaustive with no fallback
arm
(unlike `Time32`/`Time64`, which must reject invalid unit combinations).
- Accept `Interval(_)` in `group_column_supported_type`.
- Extend the `group_column_supported_type` ↔ `make_group_column`
consistency
  fuzz with the three Interval units.
- Add an `(Interval, Int32)` group-count benchmark to
`benches/multi_group_by.rs`.

## Are these changes tested?

Yes.
- New unit test: an `Interval` key stays on the `GroupValuesColumn`
path, dedups
including nulls, keeps "1 month" and "30 days" as **distinct** groups
(no
cross-unit folding), and round-trips with the `Interval` output type
preserved.
- The consistency fuzz now asserts all three Interval units route
through the
  dispatcher.
- New single- and multi-column `Interval` `GROUP BY` coverage in
`group_by.slt`.

## Are there any user-facing changes?

No API changes. `GROUP BY` queries with an `Interval` key now use the
column-wise fast path instead of the row-encoded fallback; results are
unchanged.

Subject: [PATCH 746/878] IN LIST: isolate branchless filter implementation
 (#23907)

## Which issue does this PR close?

- Part of #19241.
- Follow-up to #23014.

## Rationale for this change

#23014 added `BranchlessFilter` for small primitive `IN` lists. That
implementation currently sits in `primitive_filter.rs` alongside the
bitmap
and hash-based filters. This PR moves the branchless-specific types,
functions,
and tests into `branchless_filter.rs`.

The module docs explain the direct-comparison path and its per-width
limits.
They also cover why narrow types switch to bitmap filters and how nulls
are
handled.

`BranchlessFilter::try_new` also returns an execution error when the
list is
over its limit. Strategy selection rejects such lists before
constructing the
filter, so hitting that guard means the caller violated an internal
invariant.
This PR reports it as an internal error instead.

## What changes are included in this PR?

- Moves `BranchlessFilter`, its type mappings, size limits, and tests
into
  `branchless_filter.rs`.
- Adds module documentation for the comparison strategy, thresholds,
  narrow-type bitmap fallback, and null handling.
- Changes the oversized-list guard from an execution error to an
internal
  error.
- Leaves routing, thresholds, comparison behavior, and null semantics
  unchanged.

## Are these changes tested?

Yes. The existing branchless-filter tests were moved unchanged and
continue to
pass.

- `cargo fmt --all`
- `cargo test -p datafusion-physical-expr expressions::in_list --lib`
- `cargo clippy --all-targets --all-features -- -D warnings`

## Are there any user-facing changes?

No. This only reorganizes internal code and corrects an internal error
classification.

+
+//! Fast membership tests for small, fixed-width primitive `IN` lists.
+//!
+//! # Why use a branchless filter?
+//!
+//! For a short list such as `x IN (10, 20, 30)`, it can be faster to compare
+//! `x` with all three values than to build and search a hash table.
+//!
+//! "Branchless" means that the filter always checks every list value. It
+//! combines the answers with `|`, while `||` would stop at the first match.
+//! This regular sequence of comparisons is easier for the compiler and CPU to
+//! optimize.
+//!
+//! # How does it work?
+//!
+//! When the filter is built, it stores the non-null list values and chooses a
+//! comparison function for that list length. Only this small function is
+//! specialized for each length. The rest of [`BranchlessFilter`] is shared,
+//! which keeps the generated code small.
+//!
+//! Some Arrow types share the same in-memory representation. For example, a
+//! `Float32` and a `UInt32` both use four bytes per value. The filter compares
+//! those stored bits through an unsigned type of the same size, without copying
+//! the value buffer. A bit pattern is simply the bytes Arrow uses to store a
+//! value. Comparing it preserves details such as `0.0` versus `-0.0` and
+//! different NaN values. [`BranchlessFilterType`] defines these safe,
+//! same-sized mappings and checks their sizes at compile time.
+//!
+//! The fast path is intentionally limited to short lists:
+//!
+//! - 16 values for 1-byte types
+//! - 8 values for 2-byte types
+//! - 32 values for 4-byte types
+//! - 16 values for 8-byte types
+//! - 4 values for 16-byte types
+//!
+//! These numbers do not follow one size-based pattern. One- and two-byte
+//! values have an especially efficient next step: every possible bit pattern
+//! fits in a compact bitmap. For a longer list, the bitmap filter turns on one
+//! bit for each listed value, then checks membership with a direct bit lookup.
+//! This becomes a better fit before a 64- or 128-comparison branchless chain
+//! would be useful. Wider types have too many possible values for such a
+//! bitmap, so their limits are tuned separately.
+//!
+//! Larger lists use the standard filter strategy, including bitmap filters for
+//! one- and two-byte types.
+//!
+//! # What about nulls?
+//!
+//! Null list entries are omitted from the comparison chain but counted by the
+//! filter. Evaluation first records which values matched, then
+//! [`build_result_from_contains`] combines it with input nulls, list nulls, and
+//! `NOT IN` to produce the usual SQL null behavior.

 operator (#24048)

## Which issue does this PR close?

N/A

## Rationale for this change

I was trying to explain to someone recently how PartialSortExec works,
and I found the
datafusion docs weren't quite as explicit about the befits as I wanted


## What changes are included in this PR?

1. Update the PartialSortExec documentation to explain the streaming and
memory implications better, and add a worked buffering example

## Are these changes tested?

By CI

## Are there any user-facing changes?

Better docs

Subject: [PATCH 749/878] perf: skip re-slicing window partition batches with
 nothing to prune (#24047)

## Which issue does this PR close?

- Part of #23982

## Rationale for this change

After each emission, BoundedWindowAggStream prunes the rows of each
partition's buffered batch that no longer contribute to any window
frame. The prune loop re-sliced every live partition's RecordBatch even
when there was nothing to prune, allocating fresh array metadata for an
identical batch and then dropping the replaced one.

Profiling the many-partitions benchmark showed prune_state at ~39% of
the sparse case, where nearly all live partitions are quiet and almost
every slice is a no-op, and ~21% of the dense case, where most slices
prune real rows and only the partitions missed by a batch hit the no-op
path.

One simple improvement is to leave a partition's buffered batch
untouched when the prune count is zero. This avoids the array metadata
allocation churn mentioned above.

Benchmarks:

```
- linear, range, single, 100 part, dense:    44.1 ms  -> 43.8 ms (~noise)
- linear, range, single, 10000 part, dense:  171.1 ms -> 164.8 ms (-3.6%)
- linear, range, single, 32768 part, sparse: 209.4 ms -> 166.1 ms (-20.6%)
- linear, rows,  single, 10000 part, dense:  141.5 ms -> 136.4 ms (-3.7%)
- linear, range, multi,  10000 part, dense:  268.0 ms -> 261.0 ms (-2.6%)
- sorted, range, single, 10000 part:         34.0 ms  -> 34.3 ms (+0.9%)
```

## What changes are included in this PR?

See above.

## Are these changes tested?

Covered by existing tests.

## Are there any user-facing changes?

No.

Subject: [PATCH 750/878] feat: eliminate LEFT/RIGHT JOINs with redundant sides
 (#23566)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #.

## Rationale for this change

Join elimination is useful in e.g. generated queries or views, where
joined columns can end up not being used.

An explanation of when the optimization is valid, can be seen in the
docs update for `EliminateJoin`.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

Builds upon the analysis that
https://github.com/apache/datafusion/pull/22652 introduced for the
`EliminateJoin` optimization pass. We use it to detect when the
right-side of a left-join can be removed. Same symmetrical rule for
right-join elimination.


<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes, SLT additions that test the feature end-to-end.

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?
Yes, faster queries!
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Subject: [PATCH 751/878] fix: handle empty patterns in regexp_instr (#24054)

## Which issue does this PR close?

- Closes #22257.

## Rationale for this change

PostgreSQL treats empty and other zero-width regular-expression matches
as valid character-boundary matches. Before this change, `regexp_instr`
returned 0 before compiling an empty pattern, excluded the terminal
boundary from its start-position mapping, and returned 0 instead of
propagating NULL when the input was NULL and the pattern was empty.

## What changes are included in this PR?

- Let the regex implementation evaluate empty patterns instead of
returning early.
- Map the 1-based start position to UTF-8 byte boundaries including the
terminal boundary.
- Preserve NULL propagation when the input is NULL and the pattern is
empty.
- Add unit coverage for empty patterns and potentially zero-width
patterns across Utf8, LargeUtf8, and Utf8View arrays.
- Add SQL logic coverage for terminal zero-width matches and
empty-pattern NULL input.

## Are these changes tested?

Yes. The following checks pass on the current head:

- `cargo fmt --all -- --check`
- `cargo test -p datafusion-functions
regexpinstr::tests::test_regexp_instr`
- `cargo test --profile=ci --test sqllogictests -- regexp_instr.slt`
- `cargo clippy -p datafusion-functions --tests -- -D warnings`

The implementation commit was also verified with the
repository-prescribed extended workspace suite and `cargo test --profile
ci -p datafusion-cli`; the review follow-up changes add tests only.

## Are there any user-facing changes?

Yes. `regexp_instr` now returns PostgreSQL-compatible positions for
empty and potentially zero-width patterns, including at the terminal
character boundary, and returns NULL for NULL input with an empty
pattern. This does not change the public API.

Subject: [PATCH 752/878] feat(parquet): multi-column lexicographic stats
 reorder for TopK sort pushdown (#23888)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #22198 (the **P0 — multi-column lexicographic reorder** item)
- Part of #23036 (Sort Pushdown epic)

## Rationale for this change

`PreparedAccessPlan::reorder_by_statistics` (row-group level) and
`ParquetSource::reorder_files` (file level) key only off the **leading**
sort column's `min` statistic. When the leading key ties across row
groups or files — the `ORDER BY low_cardinality_col, ts LIMIT k` shape —
the reorder degenerates to a no-op, the scan reads data in disk order,
and the TopK dynamic filter's threshold improves monotonically without
ever proving a later row group unwinnable. Result: zero runtime RG
pruning and a full-file decode even though per-column statistics contain
everything needed to read the best row group first.

The end-to-end test in this PR demonstrates the failure concretely on
current main: leading key tied across 5 row groups, secondary key
clustered but stored in adversarial DESC disk order →
`row_groups_pruned_dynamic_filter=0`, all 500 rows decoded. With this
change the scan reads the best RG first and prunes the other 4.

Note the *pruning* machinery itself already handles multi-column
lexicographic dynamic filters (the leading disjunct of `a < x OR (a = x
AND b < y)` prunes on `min(a)` stats — verified by the other new e2e
test, which passes on main unmodified). The gap was purely in the
*reorder* layers feeding it.

## What changes are included in this PR?

Both reorder layers now sort lexicographically over the **longest
plain-`Column` prefix** of the sort order, using per-column `min`
statistics:

- **RG level** (`access_plan.rs`): switch from `sort_to_indices` over
the leading column's mins to `lexsort_to_indices` over per-column min
arrays. The leading key stays normalized ASC (direction still applied by
the downstream `reverse()`, unchanged); secondary keys sort by their
direction *relative to* the leading key, with null placement pre-flipped
when the reverse is coming so the post-reverse order matches the
request. The prefix walk stops at the first non-`Column` /
not-in-file-schema expression (leading-key-only graceful skips
unchanged).
- **File level** (`sort.rs`): `extract_topk_sort_info` extended from the
single leading column to the plain-`Column` prefix, comparator compares
tuple-wise with per-column direction; missing-stats files still sort
last per column.

Behavior for single-column sort orders is unchanged.

## Are these changes tested?

- 4 new unit tests for `reorder_by_statistics`: secondary tie-break,
relative secondary direction (`a ASC, b DESC`), DESC/DESC normalization
through `reverse()`, and prefix-stop on a non-`Column` secondary
expression.
- 1 new unit test for file-level reorder: secondary tie-break with
missing-stats file placement.
- 2 new end-to-end tests in `dynamic_row_group_pruning.rs`:
- multi-column sort with clustered leading key → pruning fires via the
leading disjunct (passes before this PR; guards the existing behavior),
- multi-column sort with tied leading key + adversarial disk order →
pruning fires only with this PR's lexicographic reorder.
- Existing reorder unit tests, `dynamic_row_group_pruning` integration
tests, and `topk.slt` / `sort_pushdown.slt` /
`dynamic_row_group_pruning.slt` / `dynamic_filter_pushdown_config.slt`
all pass.
- `topk_tpch` (sort-tpch `-l 100`) shows no regressions (all 11 queries
within noise; lineitem's secondary keys are not clustered when the
leading key ties, so no wins expected on that suite — the win case is
the `ORDER BY low_card, ts` shape shown in the e2e test).

## Are there any user-facing changes?

No API changes. Queries with multi-column `ORDER BY ... LIMIT` over
parquet whose leading sort key ties across row groups / files can now
skip row groups at runtime instead of decoding the whole file.

Subject: [PATCH 753/878] fix: prevent incorrect results when pushing filters
 through anti joins (#24045)

## Which issue does this PR close?
- Closes #24002.

## Rationale for this change
Pushing filters to an anti join's non-output side can produce incorrect
results.

## What changes are included in this PR?
Restrict anti-join filter pushdown to the output side while preserving
two-sided join-key pushdown for semi joins.

## Are these changes tested?
Yes, with updated unit and SQL logic tests.

## Are there any user-facing changes?
no API changes but some downstream expected plans may change

Subject: [PATCH 754/878] perf: track `BoundedWindowAggExec` Linear-mode
 watermark once per stream (#24033)

## Which issue does this PR close?

- Related to #23982

## Rationale for this change

In Linear mode, rows arrive ordered on a prefix of the window's ORDER BY
expressions, so each new row bounds every row that will arrive in the
future, even for other partitions. We exploit this by using the last row
to arrive in a batch to close window frames for all live partitions, not
just the partition to which that row belongs.

The most-recent-row-in-the-batch is conceptually per-batch state, but it
was previously implemented as per-partition state:

- `update_partition_batch` copied the last row of each incoming batch
into every live partition's `PartitionBatchState`.
- Each copy is ~(40 + 16 * n_cols) bytes (`Option<RecordBatch>` plus a
`Vec` of `ArrayRefs`); for example, withn 100k live partitions over 10
columns, that is ~20MB of duplicate state.
- Every partition visit re-evaluated the row's ORDER BY expressions.

Instead, just store the row once. Rather than copying the row into every
partition, we pass the row to window expression evaluation. This removes
`most_recent_row` and its setter from `PartitionBatchState`, which is a
breaking API change for datafusion-expr. We can also arrange to evaluate
the ORDER BY once per batch instead of once per partition.

This is a modest performance improvement and memory savings, but also a
conceptual cleanup/refactor.

Benchmarks: (using #24032)

- linear 100 partitions:           44.4 ms -> 44.5 ms (within noise)
- linear 10000 partitions:        203.3 ms -> 199.7 ms (-1.7%)
- linear sparse 32768 partitions: 236.9 ms -> 224.5 ms (-5.2%)
- linear rows 10000 partitions:   174.2 ms -> 169.4 ms (-2.4%)
- linear multi 10000 partitions:  304.6 ms -> 295.7 ms (-3.0%)
- sorted 10000 partitions:         34.2 ms -> 34.4 ms (within noise)

## What changes are included in this PR?

* Add `WindowEvalContext` parameter to `aggregate_evaluate_stateful`
* Remove `PartitionBatchState::most_recent_row` and its setter; instead
pass row via `WindowEvalContext`

## Are these changes tested?

Yes, covered by existing tests.

## Are there any user-facing changes?

Yes, API change to `datafusion-expr`.

+### `WindowExpr::evaluate_stateful` now takes a `WindowEvalContext`
+
+`WindowExpr::evaluate_stateful` (and the provided
+`AggregateWindowExpr::aggregate_evaluate_stateful` method) take a new
+`WindowEvalContext` argument carrying stream-level information that is shared
+by all partitions:
+
+```rust,ignore
+// Before
+fn evaluate_stateful(
+    &self,
+    partition_batches: &PartitionBatches,
+    window_agg_state: &mut PartitionWindowAggStates,
+) -> Result<()>
+
+// After
+fn evaluate_stateful(
+    &self,
+    partition_batches: &PartitionBatches,
+    window_agg_state: &mut PartitionWindowAggStates,
+    eval_ctx: &WindowEvalContext<'_>,
+) -> Result<()>
+```
+
+`WindowEvalContext` currently carries the most recent input row, which
+previously lived in each partition's `PartitionBatchState` (see the next
+section). The struct is `#[non_exhaustive]` so that fields can be added
+without further signature changes: construct it with
+`WindowEvalContext::default()` and set fields through its builder methods.
+
+**Who is affected:**
+
+- Implementations of the `WindowExpr` trait that override `evaluate_stateful`
+  must add the new parameter.
+- Callers of `evaluate_stateful` or `aggregate_evaluate_stateful` must pass a
+  context.
+
+**Migration guide:**
+
+```rust,ignore
+use datafusion_physical_expr::window::WindowEvalContext;
+
+// Before
+window_expr.evaluate_stateful(&partition_batches, &mut window_agg_state)?;
+
+// After
+let eval_ctx = WindowEvalContext::default()
+    .with_most_recent_row(most_recent_row.as_ref());
+window_expr.evaluate_stateful(
+    &partition_batches,
+    &mut window_agg_state,
+    &eval_ctx,
+)?;
+```
+
+Pass `WindowEvalContext::default()` when no most-recent-row watermark is
+available (for example, when the input is sorted by the partition keys and
+partition ends are detected directly).
+
+### `PartitionBatchState::most_recent_row` removed
+
+The `most_recent_row` field and the `set_most_recent_row` method have been
+removed from `datafusion_expr::window_state::PartitionBatchState`. The most
+recent input row is a property of the whole input stream rather than
+per-partition state: every partition observed the same value. It is now
+tracked once by the operator driving the evaluation and passed to window
+expressions through the new `WindowEvalContext` argument of
+`WindowExpr::evaluate_stateful` described above.
+
+**Who is affected:**
+
+- Code that read `PartitionBatchState::most_recent_row` or called
+  `set_most_recent_row`, such as custom streaming window operators.
+
+**Migration guide:**
+
+Track the most recent input row once per stream (for example, a one-row
+slice of the last non-empty input batch) and pass it to window expressions
+via `WindowEvalContext::with_most_recent_row` instead of copying it into
+each partition's state.

Subject: [PATCH 755/878] bench: add nested-type (List/Struct/Map) cases to
 first_value/last_value benchmark (#24075)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Groundwork for benchmarking #23628 (native `GroupsAccumulator` for
nested value types in `first_value` / `last_value`).

## Rationale for this change

The `first_last` benchmark only covers primitive value types today.
#23628 adds a native `GroupsAccumulator` for **nested** value types
(`List`, `Struct`, `Map`), which previously fell back to one per-group
`Accumulator` via `GroupsAccumulatorAdapter`. To measure that work we
need nested-type cases in the benchmark.

Landing this first (with the fallback path on current `main`) means that
once #23628 is in flight, a `run benchmark first_last` diff shows the
fallback → native speedup per type automatically.

## What changes are included in this PR?

- Adds `List<Int64>`, `Struct<i64,utf8,f64>`, `Map<utf8,i64>` and a
composite `List<Struct<i64,utf8>>` value column, each with the same
coverage as the primitive cases: `first_value`/`last_value` update +
merge, plus `first_value` evaluate, at 0% and 90% nulls.
- `prepare_typed_groups_accumulator` now mirrors the planner: it uses
the native `GroupsAccumulator` when the value type is supported and
otherwise falls back to a `GroupsAccumulatorAdapter` around one
per-group `Accumulator`. The same benchmark case therefore runs the
fallback on a build without native nested support and the native path on
one that has it.

## Are these changes tested?

Benchmark-only. Runs locally on `main` (all nested cases exercise the
fallback path). As a preview of the intended signal, `first_value struct
update` goes ~112ms (fallback) → ~24ms (native, with #23628) at 1024
groups.

## Are there any user-facing changes?

No — benchmark only.

Subject: [PATCH 756/878] fix(ffi): preserve aggregate null-handling support
 (#23908)

## Which issue does this PR close?

Part of #22331.

## Rationale for this change

`ForeignAggregateUDF` inherits the default
`supports_null_handling_clause`, so producer overrides are lost across
the FFI boundary.

## What changes are included in this PR?

- Forward `supports_null_handling_clause` through `FFI_AggregateUDF`.
- Use `first_value` as the positive case and `sum` as the negative case
in forced-foreign and dynamic-library tests.

## Are these changes tested?

- `cargo test -p datafusion-ffi --features integration-tests`
- `cargo clippy --all-targets --all-features -- -D warnings`

## Are there any user-facing changes?

The FFI ABI changes. Foreign libraries must rebuild against the new
DataFusion version.

Subject: [PATCH 758/878] chore(deps): bump the codeql-actions group with 2
 updates (#24080)

Bumps the codeql-actions group with 2 updates:
[github/codeql-action/init](https://github.com/github/codeql-action) and
[github/codeql-action/analyze](https://github.com/github/codeql-action).

Updates `github/codeql-action/init` from 4.37.3 to 4.37.4

<h2>v4.37.4</h2>
<ul>
<li>This version of the CodeQL Action adds support for the
<code>tools</code> input for the <code>codeql-action/init</code> step to
be specified using a <code>github-codeql-tools</code> <a
href="https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization">repository
property</a>. This feature will gradually be rolled out following the
release of this version. Once rolled out, this allows for the CodeQL CLI
version that is used in GitHub-managed workflows, such as Default Setup,
to be set to a custom value. For example, customers who run into issues
with rate limits when a new CodeQL CLI version is released can set the
value to <code>toolcache</code> to always use the CodeQL CLI version
that is available in the runner toolcache. For Advanced Setup workflows,
the value provided for <code>tools</code> in the workflow definition
always takes precedence unless the value of the repository property
starts with <code>!</code>. <a
href="https://redirect.github.com/github/codeql-action/pull/4037">#4037</a></li>
<li>Update default CodeQL bundle version to <a

<h2>4.37.3 - 22 Jul 2026</h2>
<p>No user facing changes.</p>
<h2>4.37.2 - 21 Jul 2026</h2>
<ul>
<li>The new address format for the <code>config-file</code> input that
was introduced in CodeQL Action 4.37.0 is now enabled by default. In
addition to the format described there, the <code>remote=</code> prefix
can now be used to explicitly indicate that the input refers to a remote
file. All previous input formats continue to be accepted as well. <a
href="https://redirect.github.com/github/codeql-action/pull/4023">#4023</a></li>
<li>The CodeQL Action can now make use of <a
href="https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries">configured
private registries</a> in Default Setup to retrieve CodeQL configuration
files from remote repositories that require authentication. This will
allow customers to store their CodeQL configuration in a single
repository that can then be referenced by Default Setup workflows in
other repositories. We expect to roll this and other, related changes
out to everyone in July. <a
href="https://redirect.github.com/github/codeql-action/pull/4007">#4007</a></li>
</ul>
<h2>4.37.1 - 16 Jul 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.20.6 and earlier. These versions of
CodeQL were discontinued on 1 July 2026 alongside GitHub Enterprise
Server 3.16, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3956">#3956</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.1">2.26.1</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4019">#4019</a></li>
</ul>
<h2>4.37.0 - 08 Jul 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.0">2.26.0</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3995">#3995</a></li>
<li>In addition to the existing input format, the
<code>config-file</code> input for the <code>codeql-action/init</code>
step will soon support a new <code>[owner/]repo[@ref][:path]</code>
format. All components except the repository name are optional. If
omitted, <code>owner</code> defaults to the same owner as the repository
the analysis is running for, <code>ref</code> to <code>main</code>, and
<code>path</code> to <code>.github/codeql-action.yaml</code>. Support
for this format ships in this version of the CodeQL Action, but will
only be enabled over the coming weeks. <a

<li>Cache CodeQL CLI version information across Actions steps. <a

<li>Reduce requests while waiting for analysis processing by using
exponential backoff when polling SARIF processing status. <a

<blockquote>
<h2>v4.37.4</h2>
<ul>
<li>This version of the CodeQL Action adds support for the
<code>tools</code> input for the <code>codeql-action/init</code> step to
be specified using a <code>github-codeql-tools</code> <a
href="https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization">repository
property</a>. This feature will gradually be rolled out following the
release of this version. Once rolled out, this allows for the CodeQL CLI
version that is used in GitHub-managed workflows, such as Default Setup,
to be set to a custom value. For example, customers who run into issues
with rate limits when a new CodeQL CLI version is released can set the
value to <code>toolcache</code> to always use the CodeQL CLI version
that is available in the runner toolcache. For Advanced Setup workflows,
the value provided for <code>tools</code> in the workflow definition
always takes precedence unless the value of the repository property
starts with <code>!</code>. <a
href="https://redirect.github.com/github/codeql-action/pull/4037">#4037</a></li>
<li>Update default CodeQL bundle version to <a

<h2>4.37.3 - 22 Jul 2026</h2>

<h2>4.37.2 - 21 Jul 2026</h2>
<ul>
<li>The new address format for the <code>config-file</code> input that
was introduced in CodeQL Action 4.37.0 is now enabled by default. In
addition to the format described there, the <code>remote=</code> prefix
can now be used to explicitly indicate that the input refers to a remote
file. All previous input formats continue to be accepted as well. <a
href="https://redirect.github.com/github/codeql-action/pull/4023">#4023</a></li>
<li>The CodeQL Action can now make use of <a
href="https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries">configured
private registries</a> in Default Setup to retrieve CodeQL configuration
files from remote repositories that require authentication. This will
allow customers to store their CodeQL configuration in a single
repository that can then be referenced by Default Setup workflows in
other repositories. We expect to roll this and other, related changes
out to everyone in July. <a
href="https://redirect.github.com/github/codeql-action/pull/4007">#4007</a></li>
</ul>
<h2>4.37.1 - 16 Jul 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.20.6 and earlier. These versions of
CodeQL were discontinued on 1 July 2026 alongside GitHub Enterprise
Server 3.16, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3956">#3956</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.1">2.26.1</a>.

<a
href="https://redirect.github.com/github/codeql-action/pull/3995">#3995</a></li>
<li>In addition to the existing input format, the
<code>config-file</code> input for the <code>codeql-action/init</code>
step will soon support a new <code>[owner/]repo[@ref][:path]</code>
format. All components except the repository name are optional. If
omitted, <code>owner</code> defaults to the same owner as the repository
the analysis is running for, <code>ref</code> to <code>main</code>, and
<code>path</code> to <code>.github/codeql-action.yaml</code>. Support
for this format ships in this version of the CodeQL Action, but will
only be enabled over the coming weeks. <a

Subject: [PATCH 759/878] bench: add ArrowBytesMap benchmarks (#24078)

## Which issue does this PR close?

- Refs #13867.

## Rationale for this change

This adds a focused, reproducible microbenchmark for `ArrowBytesMap` so
that
proposed implementation changes can be measured against `main` using the
same
workloads. The benchmark is intentionally separated from the
optimization, as
requested during review.

## What changes are included in this PR?

- Register a Criterion benchmark target for
`datafusion-physical-expr-common`.
- Add workloads covering:
  - unique 4-byte values;
  - unique 32-byte values;
  - 32-byte values with low cardinality.

This PR changes measurement coverage only. It does not change the
`ArrowBytesMap` implementation or runtime behavior.

## Are these changes tested?

Yes. The benchmark was previously compiled and run on Ubuntu 24.04 under
WSL2
as part of the measurements in the original combined PR. The following
checks
were also previously run against these exact benchmark files:

- `cargo fmt --all --check`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `cargo test -p datafusion-physical-expr-common --all-features`
- `cargo test -p datafusion-physical-plan group_values`

No commands were rerun for this history-only split.

## Are there any user-facing changes?

No.

Subject: [PATCH 760/878] perf: gather Linear-mode window input more
 efficiently (#24034)

## Which issue does this PR close?

- Part of #23982

## Rationale for this change

`LinearSearch::evaluate_partition_batches` issued one
`take_record_batch` call per partition present in the input batch. For
batches with many partitions, this is inefficient.

Instead, we can build a Vec of the batch's row indices that groups the
rows by partition, gather all rows with a single `take_record_batch`
call, and hand each partition a slice of the result. Batches that
contain a single partition skip the gather entirely.

Memory caveat: the emitted slices share the gathered batch's buffers. A
partition that never receives rows again retains its slice and therefore
pins the gathered batch's buffers (up to one input batch worth of memory
per input batch in the worst case). This could be addressed, e.g., with
a compaction pass to copy long-lived slices into owned buffers, but I
have omitted that for now.

Benchmarks: (using #24032)

- linear 100 partitions:           44.3 ms -> 44.1 ms (within noise)
- linear 10000 partitions:        199.8 ms -> 170.1 ms (-14.9%)
- linear sparse 32768 partitions: 224.6 ms -> 205.3 ms (-8.6%)
- linear rows 10000 partitions:   169.0 ms -> 142.0 ms (-15.9%)
- linear multi 10000 partitions:  295.9 ms -> 268.2 ms (-9.4%)
- sorted 10000 partitions: 34.0 ms -> 34.5 ms (+1.3%; unchanged code
path)

## What changes are included in this PR?

- Rewrite `get_per_partition_indices` and rename to
`compute_partition_permutation`
- Add focused unit test for computing partition permutations correctly

## Are these changes tested?

Yes, new test added.

## Are there any user-facing changes?

No.

Subject: [PATCH 761/878] Docs: Update PR template to ask for user-visible
 rationale (#24053)

## Which issue does this PR close?

- Part of #23839.

## Rationale for this change

PR descriptions are most useful when they describe the problem being
solved from the user's point of view, rather than describing what is
wrong with some part of the code.


## What changes are included in this PR?

1. Update `.github/pull_request_template.md` to ask authors to explain
the problem in terms of user-visible behavior (with an example), and to
add the `api change` label for breaking public API changes.

## Are these changes tested?

No tests needed: template-only change.

## Are there any user-facing changes?

No changes to the code or documentation; contributors will see the
updated
templates when opening PRs and feature requests.

Subject: [PATCH 762/878] docs: document all fields and methods of
 `DFParquetMetadata` (#24037)

## Which issue does this PR close?

- Something I noticed while working on
https://github.com/apache/datafusion/pull/24036

## Rationale for this change

`DFParquetMetadata` had several fields and methods with no doc comments,
or only a one-line description, making it hard to understand their
purpose without reading the implementation.

## What changes are included in this PR?

Add doc comments

## Are these changes tested?

No behavior changed, only doc comments were added; existing tests cover
the code.

## Are there any user-facing changes?

No functional changes; public API doc comments are improved.

Subject: [PATCH 763/878] chore(deps): bump cryptography from 48.0.1 to 50.0.0
 (#24091)

Bumps [cryptography](https://github.com/pyca/cryptography) from 48.0.1
to 50.0.0.
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/pyca/cryptography/blob/main/CHANGELOG.rst">cryptography's
changelog</a>.</em></p>
<blockquote>
<p>50.0.0 - 2026-07-31</p>
<pre><code>
* **SECURITY ISSUE**:

:func:`~cryptography.hazmat.primitives.serialization.pkcs7.pkcs7_decrypt_der`
and its PEM and S/MIME variants no longer expose distinguishable errors
or
timing when unwrapping a ``RecipientInfo``'s ``encryptedKey``, which
could
act as a Bleichenbacher oracle for callers that decrypt untrusted
messages.
A random key is now substituted on failure, as described in :rfc:`3218`.
  Credit to **@X1AOxiang** for reporting the issue. **CVE-2026-69247**
* Deprecated Diffie-Hellman key exchange over finite fields (FFDH).
  Everything FFDH is deprecated, including the types in
``cryptography.hazmat.primitives.asymmetric.dh`` and loading FFDH keys
or
  parameters with the key loading APIs. Users should migrate to a more
  modern key exchange algorithm.
* Added ``xof()`` class methods to
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE128` and
:class:`~cryptography.hazmat.primitives.hashes.SHAKE256` for
constructing
  algorithm instances configured for use with
  :class:`~cryptography.hazmat.primitives.hashes.XOFHash`.
* The :mod:`X.509 verification &lt;cryptography.x509.verification&gt;`
APIs are now
  considered stable and are subject to our API stability policy.
* Added the :doc:`/cobblestone` recipe, an implementation of the
  Cobblestone-128 and Cobblestone-256 instantiations of the `C2SP
  chunked-encryption specification
&lt;https://c2sp.org/chunked-encryption&gt;`_ for streaming
authenticated
  encryption of large messages.
* Parsing a Signed Certificate Timestamp list now rejects encodings that
carry trailing bytes after the list or after an individual SCT, instead
of
  silently ignoring them.
* Added support for using :class:`~cryptography.x509.Name` as a field
type in
  the :doc:`/hazmat/asn1/index` module.
* Loading a public key or an EC private key now rejects DER where the
``subjectPublicKey`` (or EC ``publicKey``) ``BIT STRING`` declares a
non-zero
  number of unused bits, instead of silently ignoring it.
* Parsing a CRL entry's ``InvalidityDate`` extension now rejects a
``GeneralizedTime`` that carries fractional seconds or another non-DER
form,
matching the strict encoding already required for every other X.509 time
  field.
* :func:`~cryptography.x509.ocsp.load_der_ocsp_request` and
:func:`~cryptography.x509.ocsp.load_der_ocsp_response` now reject a
request
or response whose ``version`` field is not ``v1``, the only version
defined
by RFC 6960, matching the version validation already performed when
loading
  certificates, CSRs and CRLs.
* :class:`~cryptography.hazmat.primitives.hashes.XOFHash` is now
supported
  when building against AWS-LC.
* HMAC (and therefore PBKDF2-HMAC) with SHA-3 hashes is now supported
when
  building against AWS-LC.
* Diffie-Hellman (:doc:`/hazmat/primitives/asymmetric/dh`) is now
supported
  when building against AWS-LC.
&lt;/tr&gt;&lt;/table&gt;

From 9eb31bfd1621cf9512c32dbf401467ff7ae32648 Mon Sep 17 00:00:00 2001
From: Alessandro Solimando <asolimando@apache.org>

Subject: [PATCH 764/878] fix(physical-plan): preserve Exact(0) in FilterExec
 for null_count, distinct_count and total_byte_size upon empty input (#24000)

## Which issue does this PR close?

- Part of #8227

## Rationale for this change

Follow-up to #23936 (suggested
[here](https://github.com/apache/datafusion/pull/23936#discussion_r3672861490)).

#23936 made `FilterExec` report `num_rows: Exact(0)` for a provably
empty result. Two places in the same operator still turn the same proof
into an estimate:

- `cap_at_rows` demotes `null_count` and `distinct_count`
unconditionally
- `total_byte_size` is computed after the "infeasibility branch", so a
contradictory predicate (`a = 1 AND a = 2`) gives `Exact(0)` for
`num_rows` and per-column `byte_size` but an inexact `total_byte_size`

## What changes are included in this PR?

- `cap_at_rows` now maps an `Exact(0)` row bound to `Exact(0)`
- `statistics_helper` reports `total_byte_size: Exact(0)` for a
contradictory predicate instead of routing it through the selectivity
estimate

## Are these changes tested?

Yes, both by extending
`test_filter_statistics_preserves_exactly_empty_input` with two
assertions.

Both assertions were confirmed to fail without the respective fix. No
sqllogictest baselines change.

## Are there any user-facing changes?

No breaking changes and no signature changes. `FilterExec` reports exact
rather than inexact zeros for these statistics, visible in `EXPLAIN`
output that shows statistics.

reviewed the output and it matches my intention and understanding.

Subject: [PATCH 765/878] fix: UnionExec now conforms each batch to the union's
 declared schema (#23861)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23862.
- Related to #15394.

## Rationale for this change

`UNION ALL` between an input whose column is `NOT NULL` and an input
where the same column is nullable produces a valid, correctly-typed
logical plan — the analyzer already OR's nullability across legs in
`coerce_union_schema`
(`datafusion/optimizer/src/analyzer/type_coercion.rs`), so the union's
*declared* schema correctly reports the field as nullable.

The bug is at execution time: `UnionExec::execute()` hands out each
child's `RecordBatch`es completely unchanged. A leg whose column was
already `NOT NULL` (and therefore needed no `CAST` from the analyzer)
keeps emitting batches with a `NOT NULL` field, contradicting the
union's own declared (nullable) schema. DataFusion's own execution
tolerates this silently, but any consumer that checks schema equality
across batches from the same stream — most notably
`pyarrow.Table.from_batches` via the Arrow C Stream FFI used by the
`datafusion` Python bindings — rejects the stream with `ArrowInvalid:
Schema at index N was different`, even though every individual `SELECT`
runs fine on its own.

### Minimal reproducible example (Python)

```python
import pyarrow as pa
from datafusion import SessionContext

ctx = SessionContext()
ctx.register_record_batch(
    "table_a",
    pa.record_batch(
        {"id": [1, 2], "status": ["ok", "ok"]},
        schema=pa.schema([("id", pa.int64()), ("status", pa.string())]),  # NOT NULL
    ),
)
ctx.register_record_batch(
    "table_b",
    pa.record_batch(
        {"id": [3, 4], "status": ["done", None]},
        schema=pa.schema([("id", pa.int64()), ("status", pa.string(), True)]),  # nullable
    ),
)

df = ctx.sql("SELECT id, status FROM table_a UNION ALL SELECT id, status FROM table_b")
print(df.schema())  # status: string, nullable -- correct
df.to_pandas()      # raises pyarrow.lib.ArrowInvalid: Schema at index 1 was different
```

The same root cause is why `#16627` had to make the sqllogictest
`convert_batches` helper tolerant of this exact mismatch instead of
failing, and why `#15603` (stale, closed for inactivity) attempted a
similar fix at the physical-execution layer but didn't land.

## What changes are included in this PR?

- `datafusion/physical-plan/src/union.rs`: `UnionExec::execute()` now
compares each child stream's schema against `UnionExec`'s own declared
schema, and if they disagree, wraps the child stream in a small new
`SchemaConformingStream` that re-stamps every batch with the union's
schema before yielding it. This is always safe: the union's schema can
only be *more* permissive than any single input's (nullability is
combined with logical OR, never narrowed — see the existing
`coerce_union_schema` docs), and only the `Field::nullable` metadata
changes; the underlying array data and data type are untouched.
- `datafusion/core/tests/sql/union_nullable.rs` (new): regression tests
covering same-type nullable/non-nullable mismatches in both leg orders,
the "both legs NOT NULL" case (schema should stay `NOT NULL`), and a
case where one leg also needs a real `CAST` (`Int32` -> `Int64`) in
addition to the nullability fix.

`InterleaveExec` (used for sorted unions) may have an analogous issue,
but I kept this PR scoped to plain `UnionExec`, which is what's reported
in #23862 / #15394 and reproduces the Python-binding failure above.

## Are these changes tested?

Yes — added `datafusion/core/tests/sql/union_nullable.rs` with 4 new
tests. I verified each one fails with a clear schema-mismatch assertion
on `main` (i.e. before this fix) and passes with it applied. Also ran
the full `datafusion-physical-plan` and `datafusion-optimizer` unit
suites, `union.slt`/`union_by_name.slt` sqllogictests, and `cargo
fmt`/`clippy` (`--no-deps`, since an unrelated pre-existing dead-code
lint in `datafusion-physical-expr` fails `-D warnings` on `main` even
without this change).

## Are there any user-facing changes?

`UNION ALL` results now consistently report the analyzer's declared
nullability on every batch, regardless of which leg produced it. No
public API changes.

Subject: [PATCH 766/878] refactor: unify `ParquetFileReader` and
 `CachedParquetFileReader` (#24036)

## Which issue does this PR close?


- Related to https://github.com/apache/datafusion/pull/24030
- Related to https://github.com/apache/arrow-rs/issues/9879

## Rationale for this change

Upstream arrow-rs is deprecating the ParquetObjectReader (see
https://github.com/apache/arrow-rs/issues/10308)

Not using the deprecated code involves copying some code for each
existing usage, and I found that `CachedParquetFileReader` and
`ParquetFileReader` are almost the same

## What changes are included in this PR?

1. unify `ParquetFileReader` and `CachedParquetFileReader`
2. make the fields non `pub`

## Are these changes tested?

Yes by CI

## Are there any user-facing changes?

There are breaking API changes, though I think for the better (things
are now encapsulated more)

+### `CachedParquetFileReader` removed; `ParquetFileReader` fields are now private
+
+`CachedParquetFileReader` duplicated `ParquetFileReader` and has been removed;
+`ParquetFileReader`'s fields are also now private, with
+`file_metrics()` and `partitioned_file()` accessors added for the two that
+were previously public.
+
+**Who is affected:**
+
+- Code that names the `CachedParquetFileReader` type.
+- Code that constructs a `ParquetFileReader` directly via a struct literal, or
+  reads/writes its fields.
+
+**Migration guide:**
+
+`ParquetFileReader::new` is no longer public; build a reader through
+`ParquetFileReaderFactory::create_reader` (via `DefaultParquetFileReaderFactory`
+or `CachedParquetFileReaderFactory`) instead of constructing one directly:
+
+```rust,ignore
+// Before
+let inner = ParquetObjectReader::new(Arc::clone(&store), location).with_file_size(size);
+let reader = CachedParquetFileReader::new(
+    file_metrics,
+    store,
+    inner,
+    partitioned_file,
+    metadata_cache,
+    metadata_size_hint,
+);
+
+// After
+let reader = CachedParquetFileReaderFactory::new(store, metadata_cache)
+    .create_reader(partition_index, partitioned_file, metadata_size_hint, &metrics)?;
+```
+
+Replace field access with the new accessor methods:
+
+```rust,ignore
+// Before
+let bytes_scanned = reader.file_metrics.bytes_scanned.value();
+let location = &reader.partitioned_file.object_meta.location;
+
+// After
+let bytes_scanned = reader.file_metrics().bytes_scanned.value();
+let location = &reader.partitioned_file().object_meta.location;

Subject: [PATCH 768/878] perf: use Vec in ArrowBytesMap (#24071)

## Which issue does this PR close?

- Closes #13867.

## Rationale for this change

`ArrowBytesMap` only requires growable byte storage while values are
being
inserted. `BufferBuilder<u8>` wraps `MutableBuffer`, whose allocations
use
64-byte alignment. This alignment is unnecessary for byte storage and
makes
buffer growth more expensive.

A `Vec<u8>` provides the required append, lookup, length, and capacity
operations. When the map is materialized, `Buffer::from_vec` transfers
the
allocation into an Arrow `Buffer` without copying it.

## What changes are included in this PR?

- Replace the internal `BufferBuilder<u8>` in `ArrowBytesMap` with
`Vec<u8>`.
- Use `extend_from_slice` when storing new values.
- Convert the completed `Vec<u8>` into an Arrow `Buffer` without
copying.
- Add a focused Criterion benchmark covering:
  - unique 4-byte values;
  - unique 32-byte values;
  - 32-byte values with low cardinality.

This PR intentionally changes only `ArrowBytesMap`. The other structures
mentioned in #13867 are left for separate follow-up PRs.

## Are these changes tested?

Yes.

Validation performed on Ubuntu 24.04 under WSL2 with Rust 1.97.0:

- `cargo fmt --all --check`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `cargo test -p datafusion-physical-expr-common --all-features`
  - 80 unit tests passed
  - 8 doctests passed
- `cargo test -p datafusion-physical-plan group_values`
  - 65 tests passed

### Benchmark results

Criterion comparison against the `BufferBuilder<u8>` implementation at
commit `f9dde71ec`, using 100 samples, a 3-second warm-up, and a
5-second
measurement period:

| Benchmark | BufferBuilder | Vec | Criterion result |
|---|---:|---:|---|
| `short_unique` | 306.39 us | 302.80 us | Within noise threshold |
| `long_unique` | 410.23 us | 159.08 us | 61.24% lower time |
| `long_low_cardinality` | 49.90 us | 48.97 us | No change detected |

For `long_unique`, throughput increased by approximately 158%. Repeating
the
comparison with the execution order reversed produced approximately
158.57 us
for `Vec` and 440.05 us for `BufferBuilder`.

No stable performance regression was observed in the short-value or
low-cardinality cases.

## Are there any user-facing changes?

No. This is an internal implementation and performance change with no
public
API or behavior changes.

Subject: [PATCH 770/878] feat(functions-aggregate): support nested types
 (List, Struct, Map) in first_value / last_value GroupsAccumulator (#23628)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Closes #23601.
Part of the epic #23600.

## Rationale for this change

`first_value(x ORDER BY o)` / `last_value(x ORDER BY o)` currently fall
back to the per-group `Accumulator` path whenever `x` is a nested type
(`List`, `LargeList`, `Struct`, `Map`, ...), because
[`groups_accumulator_supported()`](https://github.com/apache/datafusion/blob/main/datafusion/functions-aggregate/src/first_last.rs)
whitelists only scalar primitives and byte types.

Two consequences we hit:

- The per-group `Accumulator` path calls `ScalarValue::try_from_array`
on every candidate row, and stores `ScalarValue::List` (or
`ScalarValue::Struct`, ...) as an `Arc` slice into the source batch. For
wide payloads this both allocates heavily per row and *pins the source
batch* in memory for every group whose current winner came from it. On
high-cardinality dedup queries (`SELECT DISTINCT ON`, `ROW_NUMBER() =
1`, single-pass `FIRST_VALUE(...ORDER BY)` over a wide `List<Struct>`)
that combination can OOM even when the final output would fit
comfortably.
- This is also what #16620 (`Performance of DISTINCT ON (columns)`)
reports at the SQL layer.

## What changes are included in this PR?

Adds a new `GenericValueState` in `first_last/state.rs` — a
`Vec<Option<ScalarValue>>`-backed `ValueState` — and wires it into
`create_groups_accumulator` for nested types. The state uses
`ScalarValue::compact()` after `try_from_array` so the stored winner is
an owned copy instead of an `Arc` slice into the source batch (otherwise
the fast path would still pin source batches even though the
accumulator's own reported size looks small).

Types now supported by the `GroupsAccumulator` fast path:

- `List`, `LargeList`, `ListView`, `LargeListView`
- `FixedSizeList`
- `Struct`
- `Map`

The existing `PrimitiveValueState` (scalar primitives) and
`BytesValueState` (Utf8 / Binary variants) paths are unchanged.

## Are these changes tested?

Yes.

- 9 unit tests in `first_last/state.rs` covering `List<Utf8>`, `Struct`,
`LargeList`, `FixedSizeList`, `Map`, `EmitTo::First(n)` partial emit,
null handling, size accounting on overwrite and shrink, and a dedicated
regression test
(`test_generic_value_state_compact_releases_parent_batch`) that verifies
`compact()` releases the `Arc` reference to the source batch.
- 2 integration tests in `first_last.rs` exercising the full
`FirstLastGroupsAccumulator<GenericValueState>` for `List<Int32>`: one
functional multi-batch test, and one that asserts the accumulator's
reported `size()` stays proportional to `#groups` rather than `#rows` on
a 10-group × 10 000-row workload.

`cargo fmt` and `cargo clippy -p datafusion-functions-aggregate --lib
--tests -- -D warnings` are clean.

## Are there any user-facing changes?

Yes, but only in the sense that a previously-slow / OOM-prone path
becomes fast for the affected data types. No SQL or API surface changes;
the same queries run without modification and previously-passing tests
continue to pass.

## Follow-ups

- Add a benchmark comparing the two code paths on wide-payload
aggregates so the memory improvement is measurable in-tree.
- The two remaining sub-issues in the epic build on this one:
- #23602 — coalesce peer `FIRST_VALUE(... ORDER BY o)` expressions into
a single struct accumulator.
- #23603 — logical rewrite `Filter(row_number() = 1) →
Aggregate(FIRST_VALUE(... ORDER BY o))`. Depends on this PR to emit the
fast path.

Subject: [PATCH 771/878] fix: do not derive ordering for arithmetic that can
 overflow (#23910)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23902.

## Rationale for this change

Please check the issue for details but the main idea is that `a + b`
over two
sorted columns is not guaranteed to be sorted.

## What changes are included in this PR?
Ordering is discarded when it overflows or wraps

## Are these changes tested?

Yes, adjusted existing tests and added a regression test in `order.slt`.

## Are there any user-facing changes?
no api changes

Subject: [PATCH 772/878] fix: preserve projection field metadata during
 physical planning (#23981)

## Which issue does this PR close?

  - Closes #23529.

  ## Rationale for this change

Logical projection aliases can attach field metadata, but physical
projection planning derived its output schema only from the unwrapped
physical expressions. This caused schema validation to reject
  aggregates above such projections.

  ## What changes are included in this PR?

- Apply logical projection schema and field metadata when constructing
`ProjectionExec`.
- Preserve the existing physical derivation of field names, types, and
nullability.
- Add metadata-aware constructors across the physical-expression and
physical-plan crate boundary.
  - Cover projections with alias metadata followed by aggregation.

  ## Are these changes tested?

Yes. A focused physical planner regression test reproduces the original
schema mismatch and passes with the fix. The relevant core and
physical-plan unit suites, targeted all-targets/all-features
  clippy, formatting, and diff checks also pass.

  ## Are there any user-facing changes?

Projection field metadata is now preserved in physical plans. Two
additive constructor methods support passing projection schema metadata
across crate boundaries; no existing API is changed.

Subject: [PATCH 773/878] perf: preallocate RowsGroupColumn buffers in take_n
 (#24070)

## Which issue does this PR close?

- Closes #23994

## Rationale for this change

Currently `RowsGroupColumn`'s `take_n` method knows the remaining number
of rows and bytes after taking the first n group rows, but when invoking
`empty_rows` passes in 0 for the row capacity and data capacity
parameters instead of the known remainders, potentially causing
unnecessary copying and allocating

## What changes are included in this PR?

Using the known remaining number of rows and bytes in the invocation to
`empty_rows`

## Are these changes tested?

Yes

## Are there any user-facing changes?

No

Subject: [PATCH 774/878] Add config-matrix tests in enforce_distribution.rs
 for range-satisfaction settings (#23627)

## Which issue does this PR close?

- Closes #23572
- Part of #22395

## Rationale for this change

Range partitioning reuse is controlled by shared optimizer settings, but
the same configuration combinations were repeated across
operator-specific SQL logic tests. This PR moves that shared coverage
into one table-driven Rust test while retaining the operator-specific
cases that test separate planning behavior.

## What changes are included in this PR?

- Extends `RequirementsTestExec` with a configurable input distribution.
- Adds a 12-row configuration matrix covering 36 combinations of key
compatibility, subset threshold, preserve-file setting, and target
partition count.
- Requires reuse cases to contain no repartition and Hash cases to
contain exactly one Hash repartition.
- Removes three redundant aggregate SLT cases and renumbers the
remaining tests.

## Are these changes tested?

Yes. The 36-cell matrix and `range_partitioning.slt` pass.

## Are there any user-facing changes?

No. These changes only affect tests and test utilities.

Subject: [PATCH 775/878] feat: add Spark-compatible atan2 function (#23962)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23961
- Part of #15914

## Rationale for this change

Spark provides [`atan2(exprY,
exprX)`](https://spark.apache.org/docs/latest/api/sql/#atan2), which
returns the angle in radians between the positive x-axis and the point
given by the coordinates (`exprX`, `exprY`). It was not yet implemented
in `datafusion-spark` — only an auto-generated test stub existed at
`spark/math/atan2.slt` with its query commented out.

## What changes are included in this PR?

- Add `SparkAtan2` (implementing `ScalarUDFImpl`) in
`datafusion/spark/src/function/math/atan2.rs`, computing `y.atan2(x)`
element-wise via the Arrow `binary` kernel.
- Register it in `datafusion/spark/src/function/math/mod.rs`.
- Enable the `atan2.slt` sqllogictest.

The signature is `exact(Float64, Float64) -> Float64`, following the
`datafusion-spark` convention of only accepting Spark-supported types.
NULL in either argument propagates to NULL.

Note: DataFusion core already has an `atan2`, but this is implemented
self-contained rather than delegating — matching the crate convention,
where 14 of the 15 existing `math` functions reimplement rather than
wrap core (including `abs`, `ceil`, `floor`, `round`, `rint`, all of
which also exist in core; only `pow` delegates, as a special case). This
keeps the Spark function library complete and consistent.

## Are these changes tested?

Yes — `datafusion/sqllogictest/test_files/spark/math/atan2.slt` covers:
- standard angles and all four quadrants (atan2 is quadrant-aware via
the signs of both arguments),
- both axes and the negative x-axis (atan2's range extends to π, unlike
`atan`),
- NULL propagation (either argument) and NULL-beats-Infinity,
- NaN in every position, including `atan2(NaN, Infinity) = NaN` (for
atan2, NaN propagates even over Infinity — unlike `hypot`, where
Infinity dominates),
- all four infinity quadrants and the one-infinite-argument cases,
- signed zeros (`atan2(-0, -1) = -π`),
- the array path (including a NULL row).

## Are there any user-facing changes?

Yes — adds the Spark-compatible `atan2` scalar function to
`datafusion-spark`. No breaking changes to public APIs.

From 3e3a92de29ed3d454e72c7bade6328508b6098c6 Mon Sep 17 00:00:00 2001
From: Adam Gutglick <adamgsal@gmail.com>
Date: Wed, 5 Aug 2026 14:20:27 +0100
Subject: [PATCH 777/878] feat: Calculate non-distinct `sum` from column
 statistics when available (#23863)

## Which issue does this PR close?

- Closes #23858.

## Rationale for this change

Seems like a valuable optimization for sources that report the `sum`
statistic.

## What changes are included in this PR?

Implements `Sum::value_from_stats`, supporting direct column expressions
and `cast(col)` expressions introduced by type coercion.

Casts direct-column statistics to the aggregate return type so decimal
sums use the widened `SUM` type.

## Are these changes tested?

Unit coverage for statistics-backed `SUM` values and decimal accumulator
widening, plus core integration coverage for integer and decimal sums
from statistics.

## Are there any user-facing changes?

None

Subject: [PATCH 778/878] Add support for running sql benchmarks with command
 line arguments (#23772)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

  - Part of #21706 and #21937

## Rationale for this change

SQL benchmark suites expose configuration through environment variables.
Contributors must consult the source or documentation to discover
suite-specific settings, and Cargo does not forward custom arguments to
benchmark targets.

This change lets `benchmark_runner` expose those settings as validated
command-line arguments. It also adds suite-specific help and a dry-run
mode for inspecting resolved configuration without executing a
benchmark.

## What changes are included in this PR?

This PR adds TOML `.suite` metadata files that define each SQL benchmark
suite’s:

  - Description and help examples.
- Suite-specific options, defaults, environment variables, and accepted
values.
  - Query filename pattern.
  - Data-path replacements.

  `benchmark_runner` uses this metadata to:

  - Generate suite-specific command-line arguments and help output.
- Resolve suite options using command-line, environment-variable, and
default-value precedence.
  - Support `--path` for suites that declare a `DATA_DIR` replacement.
  - Support `--result-mode` for result persistence and validation.
- Validate suite names, metadata, option conflicts, query identifiers,
and incompatible arguments.
- Provide `--dry-run` JSON output containing the resolved options,
paths, value sources, filters, and execution mode without loading
benchmark
  definitions or executing SQL.

The existing basic runner, Criterion mode, and suite-listing
functionality remain in place.

  ## Are these changes tested?

  Yes. New tests cover:

  - Suite metadata parsing and validation.
  - Dynamic suite options and help output.
- Option precedence between command-line arguments, environment
variables, and defaults.
  - Path and query filename resolution.
  - Dry-run output and validation.
  - Result-mode resolution.
  - Invalid option combinations and malformed metadata.

## Are there any user-facing changes?

Yes. Contributors can configure suite-specific settings through
command-line arguments and inspect them through suite help:

  ```shell
cargo run -p datafusion-benchmarks --release --bin benchmark_runner --
tpch --help

cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- \
    tpch --query 15 --format csv --path /path/to/tpch

cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- \
    clickbench --partitioning partitioned --dry-run
```

  Environment variables remain supported for compatibility with direct cargo bench invocations and existing benchmark definitions.

  The SQL benchmark README documents the command-line options, resolution precedence, dry-run behaviour, and .suite metadata format.

I have a script that cover a large number of combinations to exercise the benchmark_runner as much as possible.

 # Running Benchmarks
 
-The easiest way to run a benchmark is to use the `bench.sh` shell script (up one level from this document)
-as it takes care of configuring any required environment variables and can populate any required data files.
-However, it is possible to directly run a sql benchmark using the `cargo bench` command. For example:
+Use `benchmark_runner` to run SQL benchmarks. It reads each suite's `.suite`
+file and exposes the suite's configuration as command-line options. Use the
+`bench.sh` shell script one level above this directory to download or generate
+required data files.
 
 ```shell
-BENCH_NAME=tpch cargo bench --bench sql
+cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- tpch
 ```
 
+## SQL benchmark runner
+
+The `benchmark_runner` binary discovers suites from this directory and exposes
+suite-specific options alongside the common benchmark options. The suite name
+must come before all options.
+
+```bash
+cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- --list
+cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- tpch --help
+cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- tpch --query 15 --format csv
+cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- clickbench --partitioning partitioned --dry-run
+cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- tpch --query 1 --result-mode persist
+cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- tpch --query 1 --result-mode validate
+```
+
+Use `--path PATH` or `-p PATH` to override `DATA_DIR` for a suite that declares
+that path replacement. Suites without a `DATA_DIR` replacement reject the
+option. Suite-specific values follow this precedence: command-line option,
+environment variable, then the default in the suite metadata.
+
+`--dry-run` prints the resolved suite, filters, run mode, common options,
+suite-specific values, and path replacements as JSON. It reports source metadata
+for suite options and path replacements. It validates the command but does not
+load benchmark definitions, create a session, read datasets, execute SQL, or
+write benchmark results.
+
+Use `--result-mode persist` to save query results or `--result-mode validate` to
+compare them with saved results. The default, `--result-mode none`, does neither.
+For compatibility with direct Criterion runs, the runner also reads
+`BENCH_PERSIST_RESULTS` and `BENCH_VALIDATE`. Persistence takes precedence when
+both variables are `true`. An explicit `--result-mode` overrides both variables.
+
+### Suite metadata
+
+Each discoverable suite has one TOML metadata file named
+`<suite>/<suite>.suite`. The runner accepts these top-level fields:
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `description` | Yes | Non-empty text shown by `--list` and suite help. |
+| `query_pattern` | No | Relative benchmark filename pattern. It must contain exactly one `{QUERY_ID}` or `{QUERY_ID_PADDED}` placeholder and defaults to `q{QUERY_ID_PADDED}.benchmark`. |
+| `path_replacements` | No | Map of replacement names to paths. Relative paths resolve from the suite directory. `DATA_DIR` enables `--path/-p`. |
+| `options` | No | Array of suite-specific option tables described below. |
+| `examples` | No | Array of `command` and `description` pairs appended to suite help. Both values must contain text. |
+
+Each `[[options]]` table has these fields:
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `name` | Yes | Long option name without `--`; use lowercase ASCII letters, digits, and hyphens. |
+| `short` | No | One ASCII letter or digit without `-`. |
+| `env` | Yes | Environment variable that supplies the option value. |
+| `default` | Yes | Value used when neither the command line nor the environment supplies one. |
+| `values` | No | Accepted values. Omit the field to allow any value. Include `"..."` to allow the listed values plus any other value. Without `"..."`, the list is closed. |
+| `help` | Yes | Non-empty text shown in suite help. |
+
+Option names, short names, and environment keys must be unique within a suite.
+An option environment key cannot also appear in `path_replacements`. Suite
+options cannot reuse the runner's global names: `help` (`-h`), `query` (`-q`),
+`subgroup`, `iterations` (`-i`), `partitions` (`-n`), `batch-size` (`-s`),
+`mem-pool-type`, `memory-limit`, `sort-spill-reservation-bytes`, `debug` (`-d`),
+`simulate-latency`, `criterion`, `list`, `output` (`-o`), `save-baseline`,
+`path` (`-p`), `result-mode`, or `dry-run`.

 # Benchmark configuration
 
-Sql benchmarks are configured via environment variables. Cargo's bench command and
-[criterion](https://github.com/criterion-rs/criterion.rs) (the underlying benchmark framework) have an unfortunate
-limitation in that custom command arguments cannot be passed into a benchmark. The alternative is to use environment
-variables to pass in arguments which is what is used here.
+`benchmark_runner` is the preferred interface for configuring and running SQL
+benchmarks. Run `<suite> --help` to see the common and suite-specific options:
+
+```shell
+cargo run -p datafusion-benchmarks --release --bin benchmark_runner -- h2o --help
+```
+
+The runner maps suite options to the environment variables below for
+compatibility with benchmark files and direct Criterion runs. Direct
+`cargo bench --bench sql` invocations cannot accept custom arguments, so they
+still use environment variables.

 ## How it works
 
-SQL benchmarks are run via cargo's bench command using [criterion](https://docs.rs/criterion/latest/criterion/)
-for running and gathering statistics of each sql being benchmarked.
+The runner executes SQL benchmarks with its basic runner by default. Pass
+`--criterion` to gather statistics with
+[Criterion](https://docs.rs/criterion/latest/criterion/).
 
 Each individual benchmark is represented by a `<name>.benchmark` file that contains a number of directives instructing
 the tool on how to load data, run initializations, run assertions, run the benchmark, optionally persist and
 validate results, and finally run any cleanup if required.
 
-Variables are supported in two forms:
+Benchmark files support replacement variables in two forms:
 
-* string substitution based on environment variables (with default values if unset): \${ENV_VAR} and
+* string substitution with an optional default: \${ENV_VAR} and
   \${ENV_VAR:-default}.
-* if / else based on whether an environment variable is true or not
+* if / else based on whether a replacement value is true or not
   (\${ENV_VAR:-default|true value|false value}). In this form only the value `true` (case-insensitive) selects the
-  true branch; any other set value selects the false branch. If ENV_VAR is unset, the valud of `default` is used to
-* select the branch.
+  true branch; any other supplied value selects the false branch. If the value is absent, the parser uses `default` to

 Comments in files are supported with lines starting with # or --.

Subject: [PATCH 779/878] fix(proto): preserve empty projection when ser/de
 MemoryScanExec (#24087)

## Which issue does this PR close?

- Closes #24085

## Rationale for this change
Empty projection is not ser/de correctly in MemoryScanExec

## What changes are included in this PR?
Use same approach as `FilterExec`, `HashJoinExec` etc for projection
encode/decode

## Are these changes tested?
Yes, new roundtrip test `roundtrip_memory_source_empty_projection`,
which fails on main.

## Are there any user-facing changes?
No

Subject: [PATCH 780/878] feat: prune unread Parquet leaves when a nested
 column is cast to a narrower type (#24090)

## Which issue does this PR close?

- Related to https://github.com/apache/datafusion-comet/issues/4859. No
DataFusion issue is filed for this one.

## Rationale for this change

When a table declares a nested column narrower than the Parquet file's
physical type, DataFusion reads every leaf of the column and drops the
extra subfields in memory instead of skipping them at read time.

- DefaultPhysicalExprAdapter rewrites the projected column into CAST(col
AS narrow_type).
- Projection mask derivation only understands literal get_field chains,
so the cast's inner column expands to every physical leaf via
ProjectionMask::roots.
- Comet reported a production query reading 1.35 TB where plain Spark
read 30.9 GB for the same pruned ReadSchema (datafusion-comet#4859).
- Any embedder that hands DataFusion a pre-pruned schema (Comet,
delta-rs, Iceberg integrations) hits the same gap.

This is a port of #23398 onto current main. #23398 (stacked on the
merged #23396 and #23397, superseding an earlier attempt at #23392)
implements the fix and was reviewed favorably, but has merge conflicts
against main since a follow-up refactor moved PushdownChecker and
PushdownColumns into projection_read_plan.rs, and has four unanswered
review comments. This PR reimplements the same approach against current
main and resolves those four comments by construction:

- Drops the nested_projection_pruning config flag; the clip's total
fallback design makes a kill switch unnecessary.
- Drops an unreachable zero-name-overlap code path;
validate_struct_compatibility already rejects that case during physical
planning.
- Drops the untested union of a cast clip with a sibling get_field
access on the same root, in favor of a full read fallback for that case.
- Notes that ListView, LargeListView, and Dictionary wrappers are
conservatively left unclipped, a candidate follow up.

## What changes are included in this PR?

- New module datafusion/datasource-parquet/src/nested_schema_pruning.rs.
clip_for_cast walks the physical and cast target type trees together,
matches struct fields by name, recurses through List and LargeList, and
returns the kept leaf offsets plus the pruned Arrow type in one pass.
The clip is total: maps, dictionaries, wrapper-kind mismatches, and any
shape it does not understand keep every leaf, so the worst case is
today's full read.
- PushdownChecker in projection_read_plan.rs now also collects
CastColumnAccess entries for a CastExpr over a plain Column where the
cast requires nested struct handling. Collection is opt in and only
enabled for projection analysis, so filter pushdown is unchanged.
- build_projection_read_plan routes to a new
build_read_plan_with_cast_clipping when any cast access survives. It
partitions referenced roots into whole column reads, cast clipped reads,
get_field only reads, and full read fallbacks, including a fallback for
a root reached by both a cast and a separate get_field access.
- Fixed a pre-existing bug in the has_struct_columns fast path: it only
tested the top level field type against Struct, so a LIST STRUCT root
such as events was misclassified as containing no struct and skipped
PushdownChecker entirely, meaning cast based clipping never fired for
that shape. Replaced with a recursive contains_struct check through
List, LargeList, ListView, LargeListView, FixedSizeList, Map,
Dictionary, and RunEndEncoded.
- No new configuration option.

## Are these changes tested?

- 15 unit tests in nested_schema_pruning.rs: struct subset, reordering,
leaf promotion, missing field null fill, nested struct in struct, list
of struct, two levels of list of struct nesting, maps, dictionaries,
wrapper mismatches, and an arrow-rs roundtrip test pinning that
ProjectionMask::leaves over a subset of List Struct leaves emits exactly
the predicted type.
- 2 new unit tests in projection_read_plan.rs, plus the pre-existing
struct preservation test, unchanged.
- 8 integration tests in datafusion/core/tests/parquet/expr_adapter.rs,
asserting identical results and a bytes_scanned drop of more than 2x:
list of struct narrowing, top level struct, struct level nullability,
get_field on a narrowed struct, mixed whole column and subfield access,
filter pushdown enabled, a scan mixing a physically narrow and a wide
file, and a regression test built from the ReadSchema and InputSchema
shapes reported in datafusion-comet#4859 (a two level list STRUCT column
with a dropped struct sibling, a dropped map sibling, and dropped top
level columns).
- New
datafusion/sqllogictest/test_files/parquet_nested_schema_pruning.slt
covering the end to end SQL path.
- The existing benchmark (already merged as part of #23397) had an
assertion documenting the pre-fix baseline, narrow equals full. That
assertion now fails as expected and has been flipped to assert narrow
reads less than half of full. Measured for the top level struct case:
narrow_schema=1081 bytes vs full_schema=8398289 bytes, matching the
physically_narrow floor of 1081 bytes.

## Are there any user-facing changes?

No API changes and no new configuration option. Behavior is IO reduction
only, results are unchanged.

+//! Schema-driven nested projection pruning.
+//!
+//! When a scan's projection consumes a nested column only through a cast to a
+//! *narrower* nested type, for example the file contains
+//! `events: List<Struct<x, y, z, ...>>` but the expression is
+//! `CAST(events AS List<Struct<x, y>>)`, the Parquet reader does not need to
+//! fetch or decode the leaves the cast target never names. This module
+//! computes which Parquet leaves survive such a cast, and the Arrow type the
+//! reader will emit for them, by walking the physical and target type trees
+//! in parallel and matching struct fields by name (the equivalent of Spark's
+//! `ParquetReadSupport.clipParquetSchema`).
+//!
+//! This situation arises whenever a table's logical schema declares a nested
+//! column narrower than the physical Parquet file: the physical expression
+//! adapter rewrites the projected column into exactly such a whole-column
+//! cast (see `datafusion_physical_expr_adapter`). Engines like Spark
+//! communicate nested projection pruning to the scan this way, as a clipped
+//! read *schema* rather than as `get_field` expressions.
+//!
+//! # Safety of clipping
+//!
+//! The runtime cast for nested types
+//! ([`datafusion_common::nested_struct::cast_column`]) consumes source struct
+//! children exclusively by looking up the *target* field names, recursively
+//! through list wrappers. Physical subtrees not named by the target are
+//! provably dead: removing them from the read cannot change the cast's
+//! output. That holds for *any*
+//! [`CastExpr`](datafusion_physical_expr::expressions::CastExpr) over a
+//! nested type, not just the ones the schema adapter inserts:
+//! `ColumnarValue::cast_to` routes every
+//! cast for which
+//! [`requires_nested_struct_cast`](datafusion_common::nested_struct::requires_nested_struct_cast)
+//! holds, the same predicate the projection analysis gates on, through
+//! `cast_column`.
+//!
+//! Struct-level nullability is preserved because the Parquet reader
+//! reconstructs ancestor validity from the definition levels of any surviving
+//! leaf, so every struct level that is clipped must keep at least one leaf.
+//! A struct cast with zero field-name overlap at *any* nesting depth would
+//! break that: the reader drops a field whose leaves are all masked out, so
+//! the emitted type would not match the one predicted here. Such a cast is
+//! rejected during physical planning
+//! (`datafusion_common::nested_struct::validate_struct_compatibility`, called
+//! recursively from `DefaultPhysicalExprAdapter::rewrite`) and by the logical
+//! planner's own castability check, so it should never reach this module; if
+//! one does anyway (a custom `PhysicalExprAdapter` could build one),
+//! [`clip_for_cast`] detects the empty level and declines to clip.
+//!
+//! The clip is *total*: any type shape it does not understand (maps,
+//! dictionaries, wrapper-kind mismatches, ...) keeps all of its leaves, so
+//! the worst case is today's behavior of reading the full column. Map values
+//! are deliberately not clipped: the runtime cast routes maps through Arrow's
+//! positional struct cast, which requires all children to be present. Nor are
+//! `ListView`/`LargeListView`/`Dictionary` wrappers clipped here, even though
+//! `cast_column` does recurse through them by name. That is a conservative
+//! choice (safe, since the worst case is still just a full read) left as a
+//! candidate follow-up rather than something this module currently handles.

Subject: [PATCH 781/878] feat(pruning): expose pruning predicate IN-list
 rewrite size cap as a config option (#24074)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #24059.

## Rationale

`PruningPredicate` rewrites `col IN (v1..vn)` into a chain of per-value
min/max checks (via `build_predicate_expression`), but only when `n <=
MAX_LIST_VALUE_SIZE_REWRITE` — currently a hardcoded `20`. Beyond that,
the IN branch falls through to `unhandled_hook`, which by default
returns `TRUE`, so row-group and file-range statistics pruning does not
fire at all for IN lists longer than 20.

This is problematic for query patterns that pass a batch of identifiers
as `col IN (...)` — REST endpoints filtering by a page of ~25-100
values, ORM-generated `WHERE id IN (25 items)` queries, batched
crawlers. On a table sorted by `col`, the reader is forced to
materialize the filter column across every row group instead of skipping
row groups whose stats disagree with the IN set.

Full context in #24059.

## What changes are included in this PR?

- New config option
`datafusion.execution.parquet.pruning_max_in_list_size: usize` (default
`20`, preserving existing behaviour), placed next to
`max_predicate_cache_size` on `TableParquetOptions.global`.
- `MAX_LIST_VALUE_SIZE_REWRITE` promoted to `pub const` so callers can
reference the historical default explicitly.
- `PredicateRewriter::with_max_in_list_size(usize) -> Self` builder,
mirroring the existing `with_unhandled_hook`.
- `PruningPredicate::try_new_with_max_in_list_size` variant.
- `build_pruning_predicate_with_max_in_list_size` variant of the public
helper.
- Value threaded through `datasource-parquet`:
`ParquetSource::pruning_max_in_list_size()` reads from
`TableParquetOptions.global`, propagates through `ParquetMorselizer` →
`PreparedParquetOpen` → `RowGroupPruner`, then flows into
`build_pruning_predicates` at the opener and
`build_pruning_predicate_with_max_in_list_size` inside the dynamic
row-group pruner.

Internal `build_predicate_expression` gains a new `usize` parameter
(crate-private).

## Backward compatibility

- `PruningPredicate::try_new` and `build_pruning_predicate` are
preserved as thin wrappers that pass the historical
`MAX_LIST_VALUE_SIZE_REWRITE` default. All existing callers continue to
work with unchanged behaviour.
- The config option default is `20`, so behaviour is unchanged unless
the option is set explicitly.

## Are these changes tested?

Two new unit tests in `datafusion-pruning`:

- `row_group_predicate_in_list_rewritten_at_raised_cap`:
`PredicateRewriter::with_max_in_list_size(32)` rewrites a 25-item IN
into per-value min/max checks OR'd together, instead of falling through
to `true`.
- `row_group_predicate_in_list_disabled_at_zero_cap`: `cap = 0` skips
the IN rewrite even for small lists (opt-out path).

The existing `row_group_predicate_in_list_to_many_values` continues to
pass, guarding the default-20 behaviour.

## Are there any user-facing changes?

Yes — one new config option
(`datafusion.execution.parquet.pruning_max_in_list_size`, default `20`).
Users who want row-group / file-range pruning for IN lists longer than
20 items can raise it (e.g., `SET
datafusion.execution.parquet.pruning_max_in_list_size = 128`).

New public API on `datafusion-pruning`:

- `MAX_LIST_VALUE_SIZE_REWRITE: usize` (re-exported)
- `PredicateRewriter::with_max_in_list_size(usize) -> Self`
- `PruningPredicate::try_new_with_max_in_list_size(expr, schema, size)`
- `build_pruning_predicate_with_max_in_list_size(predicate, schema,
errors, size)`

 datafusion.execution.parquet.encoding NULL (writing)  Sets default encoding for any column. Valid values are: plain, plain_dictionary, rle, bit_packed, delta_binary_packed, delta_length_byte_array, delta_byte_array, rle_dictionary, and byte_stream_split. These values are not case sensitive. If NULL, uses default parquet writer setting
 datafusion.execution.parquet.force_filter_selections false (reading) Force the use of RowSelections for filter results, when pushdown_filters is enabled. If false, the reader will automatically choose between a RowSelection and a Bitmap based on the number and pattern of selected rows.
+datafusion.execution.parquet.max_in_list_size 20 Maximum number of values in an `IN (...)` list for which pruning will occur. Longer lists will not be used to prune files, row groups, or data pages. Higher values help in cases such as filtering on a list of ~25-100 identifiers, but also make the predicate more expensive to evaluate. Set to 0 to disable `IN (...)` list pruning entirely. Defaults to 20.
 datafusion.execution.parquet.max_predicate_cache_size NULL (reading) The maximum predicate cache size, in bytes. When `pushdown_filters` is enabled, sets the maximum memory used to cache the results of predicate evaluation between filter evaluation and output generation. Decreasing this value will reduce memory usage, but may increase IO and CPU usage. None means use the default parquet reader setting. 0 means no caching.
 datafusion.execution.parquet.max_row_group_bytes NULL (writing) Target maximum size of each row group in bytes. When set, the writer flushes whenever either this limit or `max_row_group_size` is reached, whichever comes first. Useful for bounding writer memory on wide schemas where a row-count limit can map to very different byte sizes. Matches the behavior of `parquet.block.size` in parquet-mr. If `None` (the default), only the row-count limit applies. Currently only honored when `allow_single_file_parallelism` is `false`; by default the parallel file writer ignores this limit.
 datafusion.execution.parquet.max_row_group_size 1048576 (writing) Target maximum number of rows in each row group (defaults to 1M rows). Writing larger row groups requires more memory to write, but can get better compression and be faster to read. When `max_row_group_bytes` is also set, the writer flushes a row group when either limit is reached, whichever comes first.

No effect when `coerce_int96` is `None`.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              |

Subject: [PATCH 782/878] refactor join-key equality filtering (#23843)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

### Summary
- related to https://github.com/apache/datafusion/issues/23237

Simplified and sped up candidate-pair equality filtering by eliminating
per-row type dispatch and by using a pre-built comparator that respects
`NullEquality` semantics.

Added targeted hash-join microbenchmarks to exercise high-fanout and
single hot bucket join cases with long string keys and multi column
keys.

### Description

**Before this change**, hash join probing produced candidate build/probe
row-index pairs and then equal_rows_arr validated those pairs by
materializing temporary key arrays, comparing those arrays, building a
boolean mask, and filtering the candidate indices.

**After this change**, `equal_rows_arr` validates candidate pairs by
comparing the original key arrays directly by row index using
`JoinKeyComparator`, then appending only matching candidate indices to
the output arrays. It also now checks that the input shapes are valid
before doing that work.

**Where This Happens in Hash Join**
During hash join probing, DataFusion first asks the join hash map for
candidate build/probe index pairs. Those pairs are still “candidate”
matches because the hash table is based on hash values, so DataFusion
must confirm that the actual join-key values are equal.

**Before**

For each batch of candidate pairs:

build_indices + probe_indices
  1. allocate taken build key arrays
  2. allocate taken probe key arrays
  3. allocate equality boolean arrays
  4. allocate/combine boolean masks
  5. filter index arrays
```
**After**

```
For each batch of candidate pairs:

build_indices + probe_indices
  1. compare build/probe rows directly
  2. append matching indices
```
This should particularly help workloads where:
* many candidate pairs are produced
* most candidate pairs are real matches
* join keys are multi-column

### Benchmark Performance

In https://github.com/apache/datafusion/pull/23980, we added new Q24 and
Q25 benchmarksto make this behavior visible:
* Q24 stresses a single hot long string key where every matching probe
row fans out to the whole build side.
* Q25 stresses a skewed composite join key with a long string component,
so multi-column equality filtering is exercised.

These benchmarks are meant to show whether future changes improve this
exact candidate-pair validation path which replicate the hot partition
case, not just generic hash join performance.

Query | main | branch | Change
-- | -- | -- | --
Q24: single hot bucket, high fanout | 725.4 ms | 298.3 ms | 2.43× faster
Q25: skewed multi-column string key | 299.7 ms | 139.8 ms | 2.14× faster
Q3: 100K×60M dense | 56.5 ms | 51.9 ms | 1.09× faster
Q14, Q16 | - | - | ~1.06–1.10× faster
Q1: 25×1.5M | 1.52 ms | 1.76 ms | 1.16× "slower" (0.24 ms; mostly noise)
Q4: 100K×60M, 10% hit | 141.9 ms | 153.3 ms | 1.08× slower (11 ms)
Q2, Q5–Q13, Q15, Q17–Q23 (18 queries) | - | - | no change

### Testing

- ran unit tests for the joins utilities in the physical-plan crate with
`cargo test` and the new tests
`test_equal_rows_arr_filters_candidate_pairs` and
`test_equal_rows_arr_respects_null_equality` passed.

Subject: [PATCH 783/878] fix: Fix nullability of logical `InSubquery`
 expression  (#23429)

## Which issue does this PR close?

- Closes #23428.

## Rationale for this change

Report correct nullability for `InSubquery` logical exprs.

## What changes are included in this PR?

OR the expression's and the subquery's nullability, more like
`ScalarSubquery`.

## Are these changes tested?

1. Targeted unit tests `InSubquery` nullability
2. Unit tests to verify the expression simplifier handles these queries
correctly.

## Are there any user-facing changes?

No

Subject: [PATCH 784/878] Fix syntax examples of some functions (#23212)

Almost all the datafusion functions uses a consistent format for the
`syntax_example` which describes the expected signature of the function
(that is, `func_name(arg1, arg2 [, optional_arg])`, apart from some
functions with specific syntax, e.g. [`array_agg(expression [ORDER BY
expression])`](https://datafusion.apache.org/user-guide/sql/aggregate_functions.html#array-agg)).

I'm trying to programmatically parse this syntax and map it to the
`argument` `user_doc` directive, but some of them weren't following the
same pattern.

Also properly document the `lambda` parameter of `array_transform`.

Subject: [PATCH 785/878] refactor(hash-aggr): Support spilling for `partial`
 and `final` mode aggregation (#24061)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

Part of https://github.com/apache/datafusion/issues/22710

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
This PR adds existing spilling feature into the new 2-staged (partial
and final) aggregation. The high-level implementation idea is the same
as the legacy implementation.

For the algorithm description for this feature, see top comment change
at `datafusion/physical-plan/src/aggregates/hash_stream.rs`

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->
The key changes to the operator state machine are:
In file `datafusion/physical-plan/src/aggregates/hash_stream.rs`
- `PartialHashAggregateStream::poll_next()`
- `FinalHashAggregateStream::poll_next()`

Use this as the starting point, you can navigate to all the related
changes, for example adding new states to implement larger-than-memory
execution.

This PR also includes small fixes to memory reservation in
`OrderedFinalAggregateStream`. The bugs are caught by existing tests on
aggregation spilling that is enabled in this PR.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->
Existing tests
- [x] TODO for myself: double check the `codecov`

## Are there any user-facing changes?

No
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 786/878] Proto: add DataSink serialization hook (#23752)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23498.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

`DataSinkExec` serialization currently depends on central downcasting in
`datafusion-proto`. This prevents individual `DataSink` implementations
from
owning their protobuf serialization logic.

Additionally, `FileSinkConfig` is owned by `datafusion-datasource`,
while its
protobuf conversion was implemented in `datafusion-proto`. Moving the
conversion alongside the type allows file sink implementations to reuse
it
without depending on the central proto crate.

This provides the foundation for migrating CSV, JSON, and Parquet sink
serialization in follow-up work.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Add a feature-gated `DataSink::try_to_proto` hook with a default
  implementation returning `None`.
- Make `DataSinkExec::try_to_proto` encode its input and required
ordering
  before delegating to the underlying sink.
- Retain the existing central serializer as a compatibility fallback for
  sinks that have not implemented the hook.
- Move `FileSinkConfig` protobuf encoding and decoding into
  `datafusion-datasource`.
- Keep the existing `TryFromProto` implementations as compatibility
  delegates.
- Add a helper for decoding a sink's required output ordering.
- Preserve the existing protobuf wire representation.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes.

- Added a custom `DataSink` test verifying that `DataSinkExec` delegates
  serialization with the encoded input and required ordering.
- Added coverage verifying that the direct `FileSinkConfig` conversion
and
  compatibility APIs produce the same protobuf data.
- Existing file sink round-trip tests continue to pass.
- Ran `cargo fmt --all`.
- Ran Clippy for all targets and features with warnings denied.
- Ran the required extended workspace test suite.
- Ran all 210 `datafusion-proto` integration tests.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
No. This is an internal serialization refactor. Existing protobuf data
and
the compatibility serialization path remain supported.

Subject: [PATCH 787/878] bench: multi-conjunct shared-prefix struct row-filter
 pushdown (#23524)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

  - Follow-up to review feedback on #23217.

  ## Rationale for this change

The row-filter planner in `datafusion-datasource-parquet` walks the
accessed struct-field paths for every filter, resolves the Parquet
leaves, and builds a pruned Arrow schema. When multiple predicates share
a common struct prefix, the planner can consolidate that traversal work
— this is the case the `StructAccessTree` refactor in #23217 is intended
to accelerate.

The existing bench suite does not cover this shape:

  - `parquet_struct_query` — single-field struct predicates only
    (`WHERE s['id'] = 5`).
  - `parquet_struct_projection` — projection-only, no `WHERE` clause.

So multi-conjunct shared-prefix planning is currently uninstrumented,
and the effect of consolidating access-path traversals is invisible
against the existing suite.

  ## What changes are included in this PR?


  ## Are these changes tested?


 ## Are there any user-facing changes?

  No. Benchmark-only; no library or API surface is touched.

+
+//! Benchmarks for row-filter pushdown with predicates that reach several struct
+//! leaves under a common prefix.
+//!
+//! The existing `parquet_struct_query` bench exercises single-field struct
+//! predicates only; `parquet_struct_projection` has no `WHERE` clause. Neither
+//! drives the row-filter planner with multiple accesses under the same struct
+//! root.
+//!
+//! Two properties of the planner shape these queries, and both are easy to get
+//! wrong:
+//!
+//! * `execution.parquet.pushdown_filters` must be enabled. It defaults to
+//!   `false`, in which case no row filter is built and every case below
+//!   degenerates to a plain scan.
+//! * The predicate must be a *single* conjunct. `build_row_filter` calls
+//!   `split_conjunction` before building filter candidates, and each candidate
+//!   collects its own access paths, so `s['a'] = 5 AND s['b'] = 5` becomes two
+//!   independent single-access candidates and never reaches multi-access
+//!   planning. The cases below use the `(s['a'] + s['b']) = 10` form so every
+//!   access lands in one candidate.
+//!
+//! Nested access is written `s['inner']['x']`, which the planner represents as a
+//! single flattened `get_field(s, 'inner', 'x')`. That form is pushdown-eligible;
+//! a chained `get_field(get_field(s, 'inner'), 'x')` is not.
+//!
+//! Dataset schema:
+//!
+//! ```sql
+//! CREATE TABLE t (
+//!     id INT,
+//!     s STRUCT<
+//!         a INT, b INT, c INT, d INT, e INT,
+//!         inner STRUCT<x INT, y INT, z INT>
+//!     >
+//! );
+//! ```
+//!
+//! All struct leaves mirror the top-level `id`, so a sum of `n` leaves equals
+//! `n * id` and every predicate is satisfied by exactly one row (`id = 5`).
+//! Holding the match count fixed keeps the cases comparable, and each is
+//! asserted to return that single row.

Subject: [PATCH 788/878] Proto: migrate file sink serialization (#23781)

This is a stacked PR based on #23752. Only the commits on top of #23752
are part of this review.

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23519.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

#23752 adds the `DataSink::try_to_proto` hook and moves the shared
`FileSinkConfig` protobuf conversion into `datafusion-datasource`.

This PR uses that foundation to move CSV, JSON, and Parquet sink
serialization out of the central `datafusion-proto` downcast chain.
Each concrete sink now owns its format-specific protobuf encoding and
decoding logic.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Implement `DataSink::try_to_proto` for `CsvSink`, `JsonSink`, and
  `ParquetSink`.
- Add inherent `try_from_proto` methods to reconstruct each sink's
  `DataSinkExec`.
- Repoint the physical-plan decode arms to the sink-owned decoders.
- Add feature-gated protobuf dependencies to the three format crates.
- Remove the active central `DataSinkExec` serialization dispatch after
  migrating its final built-in sink.
- Retain the old serialization helpers as deprecated compatibility
  delegates.
- Let sinks without a built-in protobuf representation fall through to
  the physical extension codec.
- Preserve the existing protobuf wire representation.

The migrations are split into one commit per sink.


## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes. Existing sink round-trip tests cover the protobuf representation.

The following checks passed:

- Focused CSV, JSON, and Parquet sink round-trip tests.
- All `datafusion-proto` integration tests.
- `cargo check -p datafusion-proto --no-default-features`.
- `cargo fmt --all`.
- `cargo clippy --all-targets --all-features -- -D warnings`.
- The required extended workspace test suite, including all 495 SQL
  logic test files.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
No functional or wire-format changes are intended.

The old compatibility helpers remain available but are deprecated.

Subject: [PATCH 789/878] refactor(pruning): deprecate
 PruningPredicate::try_new (#24129)

## Which issue does this PR close?

- Closes #24128.

## Rationale for this change

`PruningPredicateBuilder` is the extensible entry point for constructing
pruning predicates, but the construction logic still lived behind
`PruningPredicate::try_new`. Keeping the logic in the builder provides
one place to add future construction options and guides callers toward
the extensible API.

## What changes are included in this PR?

- Move pruning predicate construction into
`PruningPredicateBuilder::try_build`.
- Deprecate `PruningPredicate::try_new` and retain it as a compatibility
wrapper using the builder defaults.
- Migrate DataFusion call sites and examples to
`PruningPredicateBuilder`.
- Add a regression test confirming the deprecated constructor and
builder produce equivalent predicates.

## Are these changes tested?

Yes. The following checks pass:

- `cargo fmt --all -- --check`
- `cargo test -p datafusion-pruning`
- `cargo test -p datafusion-datasource-parquet`
- `cargo check -p datafusion-examples --examples`
- `cargo clippy -p datafusion-pruning -p datafusion-datasource-parquet
-p datafusion-examples --all-targets --all-features -- -D warnings`
- `cargo test --profile=ci --test sqllogictests`
- `cargo test -p datafusion`
- `cargo test -p datafusion-cli`
- `RUSTDOCFLAGS="-D warnings" cargo doc -p datafusion-pruning --no-deps`

The workspace-wide clippy command is currently blocked on `main` by an
existing `clippy::uninlined_format_args` diagnostic in
`datafusion/proto-common/src/generated/pbjson.rs`. The same failure
reproduces from a clean checkout of the base commit; all modified
packages pass strict clippy checks.

## Are there any user-facing changes?

Yes. `PruningPredicate::try_new` is deprecated as of 55.0.0. It remains
available as a compatibility wrapper with unchanged behavior. New
callers should construct predicates with `PruningPredicateBuilder`.

Subject: [PATCH 790/878] Preserve grouping ID during aggregate CSE (#24144)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #24143.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.

Please explain the problem you are trying to solve in terms of the
user-visible
behavior, rather than the implementation.

For example, "The code in `foo.rs` doesn't handle nulls" is a symptom of
the
implementation. "COUNT(DISTINCT) returns wrong results when the column
contains
nulls" is the user-visible problem.
-->

See #24143.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here, but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Preserve `__grouping_id` in CSE recovery projections for grouping-set
aggregates.
- Add regression coverage.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No.

Subject: [PATCH 791/878] fix: keep every spilled slice of a sort-merge join
 inner key group (#24056)

## Which issue does this PR close?

 - No issue. Found while adding test coverage in scope of #13431.

 ## Rationale for this change
Filtered semi, anti, and mark sort-merge joins kept only one finished
spill file per inner key group. If a group spilled more than once, each
spill replaced the previous file, so read-back could lose earlier rows
and produce incorrect results.

 ## What changes are included in this PR?
Keep one `InProgressSpillFile` open per inner key group, append every
overflow to it, and finalize it before filter evaluation.

 ## Are these changes tested?

 Yes:

 ```
cargo test -p datafusion-physical-plan
bitwise_multi_spill_inner_key_group
cargo test -p datafusion-physical-plan
cargo test --test sqllogictests -- sort_merge_join_spill
```

## Are there any user-facing changes?
no

+### `ParquetObjectReader` / `ParquetObjectWriter` deprecated upstream
+
+The [`parquet` crate] deprecated [`ParquetObjectReader`]
+and [`ParquetObjectWriter`] in favor of implementing
+[`AsyncFileReader`] directly (see the example on the [`AsyncFileReader`] trait and
+[`parquet/examples/object_store.rs`] in `arrow-rs`) or passing an
+[`BufWriter`] straight to [`AsyncArrowWriter`].
+
+**Who is affected:**
+
+- Custom [`ParquetFileReaderFactory`] implementations that construct a
+  [`ParquetObjectReader`] directly and now see a deprecation warning after
+  upgrading the `parquet` dependency.
+
+**Migration guide:**
+
+If your [`AsyncFileReader`] implementation exists mainly to read from an
+[`ObjectStore`] and track metrics, consider using DataFusion's
+[`ParquetFileReader`] instead of wrapping a [`ParquetObjectReader`]:
+
+```rust,ignore
+// Before
+let inner = ParquetObjectReader::new(store, location).with_file_size(size);
+Ok(Box::new(MyReader { inner, file_metrics, partitioned_file }))
+
+// After
+Ok(Box::new(ParquetFileReader {
+    file_metrics,
+    store,
+    metadata_size_hint,
+    partitioned_file,
+}))
+```
+
+If you need custom behavior (I/O coalescing, byte caching, a dedicated I/O
+runtime), implement `AsyncFileReader` directly against your `ObjectStore`,
+following the pattern in [`parquet/examples/object_store.rs`]
+
+See [PR #24030](https://github.com/apache/datafusion/pull/24030) for details.

Subject: [PATCH 794/878] refactor: move lambda variable scope into Physical
 Planning Context (#23989)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23700 .

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->
This is a clean up following #23649

## What changes are included in this PR?

- Moves the lambda-variable scope state out of `ExecutionProps` and into
`PhysicalPlanningContext`, following the same pattern as the
scalar-subquery state in #23649.

- Puts `PhysicalPlanningContext::indexes` behind an `Arc` so the new
per-lambda-body clone doesn't deep-copy the subquery index map.
`PhysicalPlanningContext::new`'s signature is unchanged.

## Are these changes tested?

- New `lambda_variables_shadow_outer_scope` unit test in
`physical_planning_context.rs` covers `with_qualified_lambda_variables`
/ `lambda_variable_qualifier` directly, including an inner lambda
shadowing an outer parameter name.

## Are there any user-facing changes?

this is a breaking change for lib users.

 ### Catalog, planner, and optimizer contracts moved to `datafusion-session`
 

From e08aed1e5de41dcf81d529140dae07723b942a5e Mon Sep 17 00:00:00 2001
From: Tim Saucer <timsaucer@gmail.com>

Subject: [PATCH 795/878] feat: Implement FFI_QueryPlanner (#24028)

## Which issue does this PR close?

- Unblocks https://github.com/apache/datafusion-python/issues/1612

## Rationale for this change

This is the last in a series of PRs that would enable FFI `Session` to
support a `QueryPlanner`. The prior work was in

- https://github.com/apache/datafusion/pull/23649
- https://github.com/apache/datafusion/pull/23703
- https://github.com/apache/datafusion/pull/23842

With those changes in place we now have the dependencies correct that we
can expose a `FFI_QueryPlanner` on a `FFI_Session`. With this we can
enable foreign libraries such as `datafusion-distributed` and `ballista`
to provide a query planner in Python and connect it directly to a
`datafusion-python`'s `SessionContext`.

## What changes are included in this PR?

Addition only. Adds these functions to `FFI_Session` and their
supporting structures:

- `query_planner()`
- `optimize()`
- `physical_optimizers()`

## Are these changes tested?

Unit and integration tests are provided.

## Are there any user-facing changes?

This is addition, but it does break the FFI ABI, which is already
evolving in DF55.

+//! FFI support for [`QueryPlanner`].
+//!
+//! A typical deployment has three libraries. Library A (for example,
+//! `datafusion-python`) owns the [`Session`] and codec registry. Library B owns
+//! a custom table provider and its extension nodes. Library C (for example,
+//! Ballista or `datafusion-distributed`) owns the query planner. A serializes a
+//! logical plan and invokes C, while `FFI_SessionRef` lets C call session
+//! services in A. C deserializes the logical plan, creates a physical plan,
+//! serializes that result, and returns it for A to deserialize. The logical and
+//! physical extension codecs preserve nodes supplied by B.
+//!
+//! The physical result is serialized instead of returned as an
+//! [`crate::execution_plan::FFI_ExecutionPlan`]. An FFI execution-plan handle is
+//! a foreign trait-object proxy, so even a built-in plan created in C cannot be
+//! downcast to its concrete
+//! type in A. Serialization reconstructs known plan nodes with A's local Rust
+//! type identities, allowing A's optimizers and other consumers to downcast
+//! them. Extension codecs control how custom nodes are reconstructed.
+//!
+//! A node returned by B while C is planning is still foreign to C unless a
+//! codec boundary reconstructs it in C. The query-planner boundary guarantees
+//! that C-local serializable nodes, and extension nodes understood by the
+//! configured codecs, are reconstructed for A when the completed plan returns.
+//!
+//! # Delegating back to library A
+//!
+//! C commonly wants A's built-in planning as a starting point, then rewrites the
+//! result. A must export its planner *before* installing C's planner on the
+//! session, and C must retain that handle: after the swap,
+//! [`Session::query_planner`] reports C's own planner, and
+//! [`Session::create_physical_plan`] dispatches to it, so either one is a
+//! self-call. Delegating to the retained handle is safe, because DataFusion's
+//! built-in physical planner never re-dispatches through [`Session`].
+//!
+//! Retain the planner rather than the session. [`FFI_QueryPlanner`] owns a
+//! reference-counted planner, so it outlives A's original session, whereas
+//! `FFI_SessionRef` borrows its session with the lifetime erased.

## Which issue does this PR close?

- Closes #24026

## Rationale for this change

`Statistics::calculate_total_byte_size `is meant to derive
`total_byte_size` from `num_rows` and the schema's fixed-width columns.
When all columns have a primitive width but `num_rows` is
`Precision::Absent`, the old code computed
`self.num_rows.multiply(&Precision::Exact(size))`, and
`Precision::multiply` returns `Precision::Absent` whenever either
operand is `Absent`. This silently overwrote any previously known
`total_byte_size` (exact or inexact) with
`Absent`, even though the non-primitive-width branch already handled
this situation correctly by downgrading the existing value to inexact
instead of discarding it.

## What changes are included in this PR?

- In `Statistics::calculate_total_byte_size`, when the schema is all
fixed-width but num_rows is` Precision::Absent,` keep the existing
`total_byte_size` and downgrade it to inexact via `to_inexact(),`
instead of overwriting it with
`Absent`.
- Updated the doc comment on `calculate_total_byte_size` to describe
this behavior.
- Added `test_calculate_total_byte_size` covering: an all-primitive
schema with known row count (exact size), an all-primitive schema with
unknown row count (preserved but downgraded to inexact), and a
non-primitive schema
  (always downgraded to inexact regardless of row count).

## Are these changes tested?

Yes — added `stats::tests::test_calculate_total_byte_size, exercising
all three branches of the updated match.

## Are there any user-facing changes?

No public API changes. Statistics propagation is more accurate
(previously known total_byte_size estimates are no longer dropped to
Absent when num_rows is unknown), which may result in slightly better
cost-based planning
  decisions in some cases.

Subject: [PATCH 797/878]  Add DataSource/FileSource proto hooks and
 FileScanConfig serde (#23683)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #23497.

## Rationale for this change

File scan serialization currently depends on central type downcasts in
`datafusion-proto`.

This PR adds the foundation needed to move each data source to its own
protobuf hooks while preserving the existing wire format and fallback
behavior.

It unblocks the concrete source migrations tracked by #23516, #23517,
and #23518.

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

## What changes are included in this PR?

- Add feature-gated `try_to_proto` hooks to `DataSource` and
`FileSource`.
- Delegate serialization from `DataSourceExec` through `FileScanConfig`
to its concrete `FileSource`.
- Add shared `FileScanConfig` protobuf encoding and decoding in the
datasource crate.
- Keep the existing central serializer as the fallback for sources that
still return `Ok(None)`.
  - Preserve the legacy protobuf wire format.
  - Add compatibility test

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

Yes

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?

This adds non-breaking, feature-gated public serialization hooks for
data source and file source implementations.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->

+//! Shared serialization of the format-agnostic [`FileScanConfig`] spine.
+//!
+//! This is the relocated body of `datafusion-proto`'s
+//! `serialize_file_scan_config` / `parse_protobuf_file_scan_config`, ported to
+//! ride the
+//! [`ExecutionPlanEncodeCtx`](datafusion_physical_plan::proto::ExecutionPlanEncodeCtx) /
+//! [`ExecutionPlanDecodeCtx`](datafusion_physical_plan::proto::ExecutionPlanDecodeCtx)
+//! instead of the raw `PhysicalExtensionCodec` +
+//! `PhysicalProtoConverterExtension`. Every
+//! `FileSource::try_to_proto` hook (CSV, JSON, Arrow, Parquet, Avro) builds its
+//! `*ScanExecNode` around [`FileScanConfig::try_to_proto`] and decodes with
+//! [`FileScanConfig::try_from_proto`], keeping a single copy of the shared
+//! wire logic. The wire format is byte-for-byte identical to the old central
+//! serializer.
+//!
+//! Child physical expressions (sort orderings, hash/range partitioning, and
+//! projection expressions) are (de)serialized through `ctx.encode_expr` /
+//! `ctx.decode_expr`; `Schema`, `Statistics`, `Constraints`, and `ScalarValue`
+//! go through `datafusion-proto-common`. Nothing here needs the raw codec.

Subject: [PATCH 798/878] add ExecutionPlan::dynamic_expressions_produced()
 method (#24068)

## Which issue does this PR close?

- Closes: https://github.com/apache/datafusion/issues/23814
- Closes:
https://github.com/datafusion-contrib/datafusion-distributed/issues/584

## Rationale for this change

External users who wish to propagate dynamic filter updates across
network boundaries need to know in which direction updates need to flow.
Thus `ExecutionPlan::apply_expressions` is not enough. The proposal in
https://github.com/apache/datafusion/issues/23814 is to provide a
separate API for dynamic filter producers.

## What changes are included in this PR?

This change adds a new method
`ExecutionPlan::dynamic_expressions_produced(&self) -> Vec<Arc<dyn
PhysicalExpr>>` which should return dynamic filters produced by the
`ExecutionPlan`.

## Are these changes tested?

Yes. Adds a new invariant that all expressions returned by
`ExecutionPlan::dynamic_expressions_produced` have an expression id.

## Are there any user-facing changes?

There's a new API, `ExecutionPlan::dynamic_expressions_produced(&self)
-> Vec<Arc<dyn PhysicalExpr>>`

Subject: [PATCH 799/878] fix(proto): preserve HashJoinExec fetch across
 serialization (#24165)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!-- No dedicated issue; found while auditing the plans covered by the
`try_to_proto`/`try_from_proto` migration EPIC. -->

- Related to #23494 (found while auditing that EPIC's plans for
unserialized
  fields). This is a bug fix, not part of the migration checklist.

## Rationale for this change

`HashJoinExec.fetch` was silently dropped by protobuf serialization.
`protobuf::HashJoinExecNode` had no `fetch` field, so `HashJoinExec`'s
`try_to_proto` never wrote it and `try_from_proto` never restored it: a
plan
with `fetch = Some(n)` round-tripped to `fetch = None`.

This is user-visible. The `limit_pushdown` physical optimizer rule
pushes a
limit into the join via `ExecutionPlan::with_fetch`, then marks the
global
state satisfied and drops the enclosing `GlobalLimitExec`. So after a
proto
round-trip the plan carried no limit at all, and a distributed executor
(Ballista/Comet-style, anything that ships physical plans over the wire)
returned more rows than the query asked for.

## What changes are included in this PR?

- `datafusion.proto`: add `optional uint64 fetch = 12` to
`HashJoinExecNode`.

The field is **presence-tracked on purpose**, and this is the
load-bearing
detail for wire compatibility. Messages written by versions predating
this
field carry no `fetch` at all, and a plain proto3 scalar decodes that
absence
  as `0`. With the negative-sentinel convention used by `SortExecNode`'s
`int64 fetch`, `0` would mean "fetch 0 rows" and would silently turn
every
older plan into an empty result. `optional` gives prost an `Option<u64>`
where absent decodes to `None`, which is the correct reading of an older
  message. A comment in the `.proto` records this.

- Regenerated `prost.rs` / `pbjson.rs` via
`datafusion/proto-models/regen.sh`
  (no hand edits).

- `hash_join/exec.rs`: write `self.fetch` in the `try_to_proto` hook and
restore it in `try_from_proto` via the builder's `with_fetch`, matching
how
  the plan is normally constructed.

- New regression test `roundtrip_hash_join_fetch`.

The deprecated `PhysicalPlanNodeExt` shims (`try_from_hash_join_exec` /
`try_into_hash_join_physical_plan`) delegate straight to these two
hooks, so
they pick the fix up with no separate change. Verified by reading them
rather
than assumed.

## Are these changes tested?

Yes. `roundtrip_hash_join_fetch` in
`datafusion/proto/tests/cases/roundtrip_physical_plan.rs` builds a
`HashJoinExec`, applies `with_fetch(Some(7))` the way `limit_pushdown`
does,
round-trips it through `physical_plan_to_bytes_with_proto_converter` /
`physical_plan_from_bytes_with_proto_converter`, and asserts `fetch()`
is
still `Some(7)`. It also covers `fetch = None`.

The assertion deliberately inspects `fetch()` rather than the plan's
string
form. The existing `roundtrip_test` helper compares
`format!("{plan:?}")`, and
`HashJoinExec`'s `Debug` output does not include `fetch` — which is
exactly why
this went unnoticed. I confirmed this empirically: with the encode side
reverted, the Debug comparison inside the helper still passes and only
the
`fetch()` assertion fails (`left: None, right: Some(7)`).

Ran locally:

- `cargo fmt --all`
- `cargo test -p datafusion-proto --test proto_integration` — 215
passed, 0 failed
- `cargo test -p datafusion-physical-plan` — 1640 + 9 passed, 0 failed
- `cargo clippy --all-targets --all-features` on the touched packages.
The
changed code is clean; the only two errors reported are pre-existing on
an
unmodified `main` with my newer local clippy (`uninlined_format_args` in
  `datafusion/proto-common/src/generated/pbjson.rs` and
`needless_pass_by_value` in `datafusion/proto/src/bytes/mod.rs`), in
files
  this PR does not touch.

## Are there any user-facing changes?

Yes, a bug fix: a limit pushed into a hash join now survives
physical-plan
serialization, so distributed executors no longer over-return rows. No
API
changes. The new proto field is backward and forward compatible in both
directions — old readers ignore tag 12, and new readers treat its
absence as
"no limit".

Subject: [PATCH 800/878] feat: Add SQL planner, physical planner, and
 TableProvider hook for MERGE INTO (#22988)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

Follow-up to #20763 (merged) which added `MergeIntoOp`,
`MergeIntoClause`, and proto types.

## Rationale for this change

`MERGE INTO` (SQL:2003) is a widely-used DML statement for
upsert/conditional update workloads. This PR wires the types introduced
in #20763 through the SQL planner, physical planner, and `TableProvider`
trait so that table implementations can actually execute merge
operations.

## What changes are included in this PR?

**`datafusion/session` — `TableProvider` trait extension**
- Add `merge_into(source, on, clauses)` async method with a default
`not_impl_err` impl so existing providers are unaffected.

**`datafusion/sql` — SQL → LogicalPlan**
- `statement.rs`: parse `Statement::Merge` into `LogicalPlan::Dml` with
`WriteOp::MergeInto`.
- Resolve the target table and plan the `USING` source into a
`LogicalPlan`.
- Build a combined target+source schema to resolve `ON` and `WHEN`
expressions.
- Convert `ON` condition and `WHEN MATCHED / NOT MATCHED` clauses to
DataFusion `Expr`.

**`datafusion/expr` — expression plumbing**
- `MergeIntoOp::exprs()`: stable iteration over all expressions (ON,
then per-clause predicate + action values).
- `MergeIntoOp::with_new_exprs()`: rebuild op from a transformed expr
vector.
- Branch `LogicalPlan::apply_expressions`, `map_expressions`, and
`with_new_exprs` on `WriteOp::MergeInto` so optimizers can rewrite merge
expressions. Other `WriteOp` variants are unchanged.

**`datafusion/core` — physical planner dispatch**
- Dispatch `WriteOp::MergeInto` in the physical planner.
- Recover the `TableProvider` via `source_as_provider()`, extract the
source `ExecutionPlan`, build the target+source merge schema, and call
`TableProvider::merge_into`.

## Unsupported MERGE SQL: implementation limitations

These are valid or reasonable MERGE forms that this PR rejects to avoid
silently producing an incorrect logical plan. They can be revisited once
the planner representation / qualifier handling supports them safely.

**Target-correlated subqueries when the target is aliased**

```sql
MERGE INTO target AS t
USING source AS s
ON EXISTS (
  SELECT 1 FROM source AS x WHERE x.id = t.id
)
WHEN MATCHED THEN DELETE;
```

Currently rejected with:

```text
MERGE subqueries correlated to target alias 't' are not supported
```

The limitation is alias canonicalization: top-level target columns can
be rewritten from `t.id` to `target.id`, but target references inside
subquery plans appear as outer-reference columns and are not rewritten
yet.

**Source qualifier collides with the real target table name**

```sql
MERGE INTO target AS t
USING source AS target
ON t.id = target.id
WHEN MATCHED THEN DELETE;
```

Currently rejected with:

```text
MERGE source may not use the target table name 'target' as a qualifier while the target is aliased as 't'; use a different source alias
```

The limitation is again qualifier canonicalization: rewriting `t.id` to
`target.id` would collide with the source alias `target` and could
change expression meaning.

**Execution still requires a provider implementation**

This PR adds the planner and `TableProvider::merge_into` dispatch point.
If the target provider does not override the default implementation,
execution fails even for supported MERGE syntax:

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN MATCHED THEN UPDATE SET val = s.val
WHEN NOT MATCHED THEN INSERT (id, val) VALUES (s.id, s.val);
```

Default error:

```text
MERGE INTO not supported for Base table
```

## Unsupported MERGE SQL: intentionally unsupported syntax

These forms are either dialect-specific, target-table modifier syntax,
or outside the initial core/common MERGE surface. This PR rejects them
explicitly rather than accepting SQL and dropping semantics.

**SQL Server-style `OUTPUT` clause**

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN MATCHED THEN DELETE
OUTPUT deleted.id;
```

Rejected with:

```text
MERGE OUTPUT clause is not supported
```

**Target table modifiers / hints / partitions / samples**

```sql
MERGE INTO target PARTITION (p0)
USING source AS s
ON target.id = s.id
WHEN MATCHED THEN DELETE;
```

```sql
MERGE INTO target()
USING source AS s
ON true
WHEN MATCHED THEN DELETE;
```

Rejected with:

```text
MERGE target table modifiers are not supported
```

**Target alias column lists**

```sql
MERGE INTO target AS t(a, b)
USING source AS s
ON t.a = s.a
WHEN MATCHED THEN DELETE;
```

Rejected with:

```text
MERGE target alias column lists are not supported
```

**Non-table targets**

```sql
MERGE INTO (SELECT * FROM target) AS t
USING source AS s
ON t.id = s.id
WHEN MATCHED THEN DELETE;
```

Rejected with:

```text
Cannot MERGE INTO non-table relation!
```

**Oracle action-level predicates**

The common conditional form is supported via `WHEN ... AND <predicate>`:

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN MATCHED AND s.is_active THEN UPDATE SET val = s.val;
```

However, Oracle-style action-level predicates are not represented in
`MergeIntoAction` and are explicitly rejected:

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN MATCHED THEN UPDATE SET val = s.val WHERE s.is_active;
```

```text
MERGE UPDATE WHERE predicates are not supported
```

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN MATCHED THEN UPDATE SET val = s.val DELETE WHERE t.val IS NULL;
```

```text
MERGE UPDATE DELETE WHERE predicates are not supported
```

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN NOT MATCHED THEN INSERT (id, val) VALUES (s.id, s.val) WHERE s.is_active;
```

```text
MERGE INSERT WHERE predicates are not supported
```

**`INSERT ROW` shorthand**

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN NOT MATCHED THEN INSERT ROW;
```

Rejected with:

```text
MERGE INSERT ROW is not supported
```

**Multiple rows in one MERGE INSERT action**

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN NOT MATCHED THEN INSERT (id, val) VALUES (s.id, s.val), (s.id + 1, s.val);
```

Rejected with:

```text
MERGE INSERT must have exactly one row of values
```

**Tuple assignment in UPDATE**

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN MATCHED THEN UPDATE SET (id, val) = (s.id, s.val);
```

Rejected with:

```text
Tuples are not supported
```

**Invalid clause/action combinations**

These are rejected by `sqlparser` before DataFusion planning. For
example, this is invalid because `WHEN NOT MATCHED` / `WHEN NOT MATCHED
BY TARGET` describes source rows without a target row, so there is no
target row to delete:

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN NOT MATCHED THEN DELETE;
```

Use `NOT MATCHED BY SOURCE` to delete target rows that have no source
row:

```sql
MERGE INTO target AS t
USING source AS s
ON t.id = s.id
WHEN NOT MATCHED BY SOURCE THEN DELETE;
```

## Are these changes tested?

- SQL planner tests cover supported MERGE planning, target/source
qualifier handling, quoted action columns, duplicate action columns,
invalid action targets, missing `WHEN`, target modifiers, and
unsupported action-level predicates.
- `sql_api` tests cover target/source qualifier collisions,
target-correlated subquery rejection, supported source-correlated and
uncorrelated subqueries through optimization, and boolean validation for
`ON` / `WHEN` predicates.
- `physical_planner` tests verify that the provider receives the
combined target+source logical schema and that physical expression
planning can resolve both target and source columns.
- Unit tests for `MergeIntoOp::exprs` / `with_new_exprs` are included in
`dml.rs`.
- Proto round-trip tests for `MergeInto` remain covered in
`datafusion/proto/tests/cases/roundtrip_logical_plan.rs`.

## Are there any user-facing changes?

- **`TableProvider`** gains a new `merge_into` method. The default
implementation returns `not_impl_err`, so existing implementations
compile without changes.
- `MERGE INTO <table> USING <source> ON <cond> WHEN ...` SQL syntax is
now accepted by the DataFusion SQL parser and planner for the supported
core forms described above.

Subject: [PATCH 801/878] fix: box aws-config loading future avoid clippy
 warning (#24175)

## Which issue does this PR close?

- N/A

## Rationale for this change

In aws-config >= 1.10, the future returned by `ConfigLoader::load()` is
large enough that it triggers the clippy `large_futures` error (as seen
in the CI failures for #24163). Fix this by using `Box::pin`.

## What changes are included in this PR?

See above.

## Are these changes tested?

Yes.

## Are there any user-facing changes?

No.

Subject: [PATCH 803/878] feat: add GroupColumn support for Decimal256 in
 multi-column GROUP BY (#23849)

## Which issue does this PR close?

- Part of #22715.

## Rationale for this change

A `Decimal256` GROUP BY key currently forces the whole grouping onto the
row-encoded `GroupValuesRows` fallback. `i256` is `Copy` and already
implements `ArrowNativeTypeOp` + `HashValue`, so it reuses the existing
`PrimitiveGroupValueBuilder`, exactly like `Decimal128`.

## What changes are included in this PR?

- Support `Decimal256` in `make_group_column` and
`group_column_supported_type`.
- Update the supported-type consistency test and add `Decimal256`
benchmark.

## Are these changes tested?

Subject: [PATCH 804/878] refactor(proto): migrate CsvSource serde (#24177)

## Which issue does this PR close?

- Part of #23516.

## Rationale for this change

Part of epic #23494. Moves `CsvSource` protobuf serialization from the
central dispatch into the source implementation.

## What changes are included in this PR?

Add protobuf serialization and deserialization to `CsvSource`, including
the CSV format options represented by the existing wire format.

Repoint the live decode arm to `CsvSource::try_from_proto` and remove
the old central encode arm. Keep `try_into_csv_scan_physical_plan` as a
deprecated compatibility wrapper that delegates to the new
implementation.

The protobuf wire format remains unchanged.

## Are these changes tested?

Yes. Added `roundtrip_csv_scan_preserves_format_options`, covering
header, delimiter, quote, escape, comment, multiline values, and
truncated rows.

## Are there any user-facing changes?

The existing `PhysicalPlanNodeExt` method remains available as a
deprecated compatibility wrapper. There is no immediate API removal or
wire-format change.

Subject: [PATCH 805/878] fix: Correctly process numeric literals with
 underscores (#24046)

## Which issue does this PR close?

- Closes #23877.

## Rationale for this change

Be able to use numeric literals with underscores as separators, which
are valid in some dialects like Postgres.

## What changes are included in this PR?

The `parse_sql_number` method now removes underscores from numbers first
before passing to the Rust parser.

## Are these changes tested?

Yes.

## Are there any user-facing changes?

No.

Subject: [PATCH 806/878] fix: typo for the builder error type (#24052)

## Which issue does this PR close?

There is no ticket for this (I can open one if it is really needed).
This is a very small nitpick QoL improvement, by changing the wording
for an error.

The typo fixes the phrase `... can't cast to got ...`, by adding a comma
and making the rest a bit clearer.

## Rationale for this change

- The error doesn't read as natural english with `... can't cast to got
...`.
- I've added more clarity on what `got` and `for` are, by changing to
`data of type` and `field of type`.

## What changes are included in this PR?

 - Rewording an error message.

## Are these changes tested?

 - I added a test to confirm the error message looks right.

## Are there any user-facing changes?

 - A user facing error message has changed.
 - No documentation changes are needed.
 - No API breaking changes are in this PR.

Subject: [PATCH 807/878] tests: add SLT test coverage for `MERGE INTO`
 (#24174)

## Which issue does this PR close?

- Follow on ot https://github.com/apache/datafusion/pull/22988 from
@wirybeaver

## Rationale for this change

In addition to planning for MERGE INTO I think we should have some SQL
level tests . Since the default MemTable doesn't implement MERGE INTO we
can mostly only test the planning, but we should still add the coverage
I think

## What changes are included in this PR?

Add slt tests for `MERGE INTO`, with mostly explain plan coverage

## Are these changes tested?

Only tests

## Are there any user-facing changes?
No

Subject: [PATCH 808/878] refactor(proto): migrate ParquetSource serde (#24169)

## Which issue does this PR close?

- Closes #23517.

## Rationale for this change

Part of epic #23494. Moves `ParquetSource` protobuf serialization from
central dispatch into the source implementation.

## What changes are included in this PR?

Add protobuf serialization and deserialization to `ParquetSource`,
including the pushdown predicate and `TableParquetOptions`. Rebuild the
cached Parquet reader factory from the runtime environment during
deserialization.


## Are these changes tested?

Yes. Existing Parquet round-trip tests cover this change.

## Are there any user-facing changes?
no

Subject: [PATCH 809/878] refactor(proto): migrate JsonSource serde (#24178)

## Which issue does this PR close?

- Part of #23516.

## Rationale for this change

Part of epic #23494. Moves `JsonSource` protobuf serialization from the
central dispatch into the source implementation.

## What changes are included in this PR?

Add protobuf serialization and deserialization to `JsonSource`.

Repoint the live decode arm to `JsonSource::try_from_proto` and remove
the old central encode arm. Keep `try_into_json_scan_physical_plan` as a
deprecated compatibility wrapper that delegates to the new
implementation.

The protobuf wire format remains unchanged.

## Are these changes tested?

Yes. Added `roundtrip_json_scan`.

## Are there any user-facing changes?

The existing `PhysicalPlanNodeExt` method remains available as a
deprecated compatibility wrapper. There is no immediate API removal or
wire-format change.

Subject: [PATCH 810/878] chore: add runendencoded & listview types to dfschema
 equality methods (#24138)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

N/A

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.

Please explain the problem you are trying to solve in terms of the
user-visible
behavior, rather than the implementation.

For example, "The code in `foo.rs` doesn't handle nulls" is a symptom of
the
implementation. "COUNT(DISTINCT) returns wrong results when the column
contains
nulls" is the user-visible problem.
-->

Some of these methods omit support for these newer types, so plugging
some holes where possible, to work towards ensuring these types have
proper support in DataFusion.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here, but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Added match arms for runendencoded & [large]listview types to dfschema
methods `datatype_is_logically_equal` and
`datatype_is_semantically_equal`

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No

Subject: [PATCH 811/878] perf: preserve dictionary encoding for `btrim`,
 `ltrim`, and `rtrim` (#24100)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Followup to #23930
- Related to #19458 and #20935

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.

Please explain the problem you are trying to solve in terms of the
user-visible
behavior, rather than the implementation.

For example, "The code in `foo.rs` doesn't handle nulls" is a symptom of
the
implementation. "COUNT(DISTINCT) returns wrong results when the column
contains
nulls" is the user-visible problem.
-->

Previously, coercion materialized dictionary-encoded inputs for `btrim`,
`ltrim`, and `rtrim`. This lost the encoding and evaluated the function
for every row instead of once per dictionary value entry.

This PR extends dictionary preservation to these trim functions.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here, but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Preserve dictionary encoding for `btrim`, `ltrim`, and `rtrim`.
- Add tests and benchmarks.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes, covered by slt

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

If there are any breaking changes to public APIs, please add the `api
change` label.
-->

These functions now preserve dictionary encoding in their output.

Subject: [PATCH 812/878] fix: support untyped NULL input for median (#24104)

## Which issue does this PR close?

- Closes #24077.

## Rationale for this change

`median(NULL)` worked in DataFusion 53 but regressed in DataFusion 54.
The untyped NULL argument remained `DataType::Null`, causing physical
planning to create a median accumulator for an unsupported input type.

## What changes are included in this PR?

- Keep the existing declarative signature for `median`.
- Handle `DataType::Null` in physical execution using `NoopAccumulator`.
- Use a Null state field for Null input.
- Fall back to the generic groups accumulator adapter for Null input.
- Add a SQL logic regression test for `median(NULL)`.

## Are these changes tested?

Yes.

- `cargo fmt --all -- --check`
- `cargo test --profile=ci --test sqllogictests -- aggregate.slt`
- `cargo test -p datafusion-functions-aggregate`
- `cargo clippy -p datafusion-functions-aggregate --all-targets
--all-features -- -D warnings`

## Are there any user-facing changes?

Yes. `median(NULL)` now returns NULL with `DataType::Null` instead of
failing during physical execution.

Subject: [PATCH 813/878] Proto: migrate MemorySourceConfig to per-source
 try_to_proto / try_from_proto hooks (#24187)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23518.
- Part of #23494.

## Rationale for this change

Continues the per-plan proto hook migration (#23494, pattern established
in #23495 and #23683): each plan/source owns its wire logic via
`try_to_proto` / `try_from_proto` hooks instead of the central
downcast/match chains in `datafusion-proto`.

## What changes are included in this PR?

- `DataSource::try_to_proto` implemented for `MemorySourceConfig` and
inherent `MemorySourceConfig::try_from_proto` added in
`datafusion/datasource/src/memory.rs` (behind the `proto` feature). The
record-batch IPC serde is pure Arrow and is inlined locally.
- The `MemoryScan` decode arm in `datafusion-proto` now delegates to
`MemorySourceConfig::try_from_proto`, and the central `MemoryScan`
encode arm in `try_from_data_source_exec` is **deleted** — proof that
the hook is the only path.
- `try_into_memory_scan_physical_plan` becomes a deprecated shim
delegating to the new hook; the now-unused `serialize_record_batches` /
`parse_record_batches` helpers are deprecated.

The wire format is byte-for-byte identical: I verified locally that a
memory scan plan (with sort information, fetch, and `show_sizes=false`)
encodes to identical bytes before and after this change, and that bytes
encoded by each version decode correctly with the other.

## Are these changes tested?

Yes. Existing roundtrip tests (`roundtrip_memory_source`,
`roundtrip_memory_source_empty_projection`) now exercise the hooks since
the central arms are gone. A new test
`roundtrip_memory_source_sort_information_and_fetch` covers
`sort_information`, `fetch`, and `show_sizes`, asserting on the decoded
`MemorySourceConfig` directly rather than only the display string.

## Are there any user-facing changes?

No behavior changes.
`PhysicalPlanNodeExt::try_into_memory_scan_physical_plan`,
`parse_record_batches`, and `serialize_record_batches` are deprecated
(still functional).

Subject: [PATCH 814/878] fix(proto): prevent logical plan serialization stack
 overflow (#24124)

## Which issue does this PR close?

- Closes #23823.

## Rationale for this change

`LogicalPlanNode::try_from_logical_plan` recursively serializes logical
plans
to protobuf. In debug builds, its large `match` compiled to a 202,304 B
stack
frame, so ten nested `SubqueryAlias` nodes over an `EmptyRelation`
overflowed
a 2 MiB thread stack.

Each arm was isolated independently against the original dispatcher:

| Independent frame effect | Arms | Examples |
| --- | ---: | --- |
| >=10 KiB reduction | 4 | TableScan: 34,608 B; Join: 11,392 B; Dml /
RecursiveQuery: 10,320 B |
| 5-8 KiB reduction | 17 | Projection, Filter, Aggregate, Repartition,
Unnest, Copy |
| 2-4 KiB reduction | 7 | Values, EmptyRelation, Union, Extension |
| <=64 B effect | 9 | Several DDL/statement arms; Subquery adds 16 B |

These effects are not additive: each change alters the compiler's layout
of
the same `match` frame. Isolating the 15 arms with the largest
independent
reductions still left a 58,560 B frame; isolating all 37 arms reduced it
to
1,680 B.

## What changes are included in this PR?

- Isolate every `try_from_logical_plan` match arm behind a debug-only
non-inlined helper, preventing arm-local temporaries from inflating the
  recursive dispatcher frame.
- Add the opt-in `datafusion-proto/recursive_protection` feature using
the
  existing DataFusion recursion pattern.
- Add child-process stack-safety regressions for the original 2
MiB-stack
  reproducer and feature-gated stack growth.

With `recursive_protection`, the dispatcher frame measures 1,648 B. The
helper is only forced out of line in debug builds.

## Are these changes tested?

Yes.

- `cargo fmt --all --check`
- `cargo check -p datafusion-proto --all-features`
- `cargo test -p datafusion-proto --lib`
- Stack-safety regression: 100 nested aliases on a 2 MiB stack.
- Feature-gated stack-growth regression: 2,000 nested aliases with
  `recursive_protection`.

## Are there any user-facing changes?

`datafusion-proto` gains an opt-in `recursive_protection` feature.
Existing
protobuf wire format, conversion behavior, and default features are
unchanged.

Subject: [PATCH 815/878] fix: prevent next_day panic on far-future start dates
 (#24194)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #23891.

## Rationale for this change

`datafusion-spark`'s `next_day` computed its result by adding the day
offset to a `chrono::NaiveDate`:

```rust
Some(Date32Type::from_naive_date(
    date + Duration::days((7 - date.weekday().days_since(day_of_week)) as i64),
))
```

When the next occurrence of the requested weekday lands past
`chrono::NaiveDate::MAX` (epoch day `95026236`) — which happens for
start dates in the last week of the representable `Date32` range — the
`NaiveDate + TimeDelta` add **panics** with `NaiveDate + TimeDelta
overflowed`. (The linked issue reports NULL; the scalar path in fact
panics.)

Spark's `DateTimeUtils.getNextDateForDayOfWeek` is pure integer
arithmetic on the epoch day and always produces a value:

```scala
def getNextDateForDayOfWeek(startDay: Int, dayOfWeek: Int): Int = {
  startDay + 1 + ((dayOfWeek - 1 - startDay) % 7 + 7) % 7
}
```

## What changes are included in this PR?

- Compute the result on the epoch day directly (`days + delta`, via
`checked_add`) instead of building a `NaiveDate` for the result, so a
next occurrence past `NaiveDate::MAX` returns a value instead of
panicking. The weekday/offset logic is unchanged, so results for all
in-range dates are identical.

Scope note: a *start* day beyond `NaiveDate::MAX` (`> 95026236`) still
returns NULL, because the weekday is derived via `NaiveDate`. Extending
full `Int`-range parity (computing the weekday arithmetically too) is a
larger change left as a follow-up; this PR fixes the panic, which is the
concrete reported harm.

## Are these changes tested?

Yes.

- Unit test `next_day_handles_far_future_start_dates` covering the two
cases from the issue (`95026236`/`Mon`, `95026230`/`Tue`), each of which
panicked before this change.
- SLT coverage in `spark/datetime/next_day.slt` asserting the same two
cases (casting the `Date32` result to `Int32`, since these dates are
past the printable range).

## Are there any user-facing changes?

`next_day` no longer panics for far-future start dates; it returns the
correct epoch day. No API changes.

Subject: [PATCH 816/878] refactor(proto): destructure plan and proto structs
 in aggregate and window serde hooks (#24166)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

<!-- No dedicated issue; this is follow-up cleanup for the proto hook
migration EPIC. -->

- Part of #23494.

## Rationale for this change

EPIC #23494 moved every built-in `ExecutionPlan` off the central
`downcast_ref` chain in `datafusion-proto` and onto per-plan hooks
(`ExecutionPlan::try_to_proto` + an inherent `FooExec::try_from_proto`)
that live in the plan's own module.

Those hooks currently read plan state through **getters**. That means
adding a field to a plan struct is invisible to serialization: nothing
breaks, the field is just silently not serialized, and the omission only
shows up later as a plan that quietly changes shape after a round-trip.

This is not hypothetical. `HashJoinExec.fetch` is dropped on round-trip
today for exactly this reason (being fixed separately). The same class
of bug is one commit away in every other plan.

This PR removes the failure mode for the aggregate, window, and
remaining misc plans by making both directions exhaustive:

- **Encode side**: each `try_to_proto` begins with an exhaustive
destructure of `self`. Every field is named — no `..`. Adding a field to
the plan struct is now a compile error until the author decides what
happens to it.
- **Decode side**: each `try_from_proto` destructures the
prost-generated node struct exhaustively. Those structs are plain,
all-`pub` and not `#[non_exhaustive]`, so this compiles — and a newly
added proto field becomes a compile error in every decoder rather than a
silently ignored wire field.

Fields that genuinely are not serialized bind to `_` with a short
comment saying why: derived at construction, runtime state, or
recomputed on decode.

## What changes are included in this PR?

Three commits, one per plan group, each green on its own:

1. `AggregateExec` / `protobuf::AggregateExecNode`
2. `WindowAggExec` and `BoundedWindowAggExec` /
`protobuf::WindowAggExecNode` (they share one decoder)
3. `UnnestExec`, `AsyncFuncExec`, `AnalyzeExec` and their nodes

All changes are confined to `datafusion/physical-plan/src/`.

**The wire format is unchanged — byte for byte.** No behavior changes.
This is a pure refactor; the encoders build the same proto messages from
the same values, just reached through destructured bindings instead of
accessors.

### Implicit coupling now documented

`WindowAggExec::can_repartition` /
`BoundedWindowAggExec::can_repartition` have no wire field of their own.
`partition_keys()` returns an empty vec when `can_repartition` is false,
and the decoder recovers the flag as `!partition_keys.is_empty()`. That
round trip was previously something you had to already know; it is now
an explicit comment on both the encode and the decode side.

### Unserialized fields the refactor documented

Fields bound to `_` because they are legitimately reconstructed rather
than transmitted:

| Plan | Field(s) | Why |
| --- | --- | --- |
| `AggregateExec` | `schema`, `required_input_ordering`,
`input_order_mode`, `cache` | derived at construction |
| `AggregateExec` | `metrics` | runtime state |
| `WindowAggExec` | `schema`, `ordered_partition_by_indices`, `cache` |
derived at construction |
| `BoundedWindowAggExec` | `schema`, `ordered_partition_by_indices`,
`cache` | derived at construction |
| `WindowAggExec` / `BoundedWindowAggExec` | `can_repartition` | no wire
field; folded into `partition_keys` (see above) |
| `UnnestExec` | `cache` (derived), `metrics` (runtime) | |
| `AsyncFuncExec` | `cache` (derived), `metrics` (runtime) | |
| `AnalyzeExec` | `cache` | derived at construction |

The `AggrDynFilter` case is also now commented: only the shared `filter`
expr goes on the wire; the per-accumulator bounds are runtime state
repopulated during execution.

### One real gap found, deliberately left alone

**`AnalyzeExec::metric_types` is not serialized.** There is no field for
it on `AnalyzeExecNode`, and `AnalyzeExecBuilder` unconditionally resets
it to `[MetricType::Summary, MetricType::Dev]`, so a non-default metric
type selection does not survive a round trip.

Fixing this requires a new proto field, which is a wire-format change
and therefore out of scope for a cleanup PR — a refactor that silently
alters the wire format would be worse than the gap it fixes. The field
is left bound to `_` with a `TODO` describing the current state, so it
can be filed and fixed separately.

## Are these changes tested?

Covered by the existing round-trip test suite, which is the actual proof
that the wire format did not move:

- `cargo test -p datafusion-proto --test proto_integration` — 214
passed, 0 failed
- `cargo test -p datafusion-physical-plan --all-features` — 1648 + 9
passed, 0 failed
- `cargo clippy -p datafusion-physical-plan --all-targets --all-features
-- -D warnings` — clean
- `cargo fmt --all`

No new tests are added: the refactor introduces no new behavior to test,
and its safety property (a forgotten field becomes a compile error) is
enforced by the compiler rather than by a test.

## Are there any user-facing changes?

No. No public API changes, no wire-format changes, no behavior changes.

Subject: [PATCH 817/878] refactor(proto): migrate AvroSource serde (#24190)

## Which issue does this PR close?

- Closes #23516.

## Rationale for this change

Part of epic #23494. Moves `AvroSource` protobuf serialization from the
central dispatch into the source implementation.

## What changes are included in this PR?

Add protobuf serialization and deserialization to `AvroSource` and add
the required `proto` feature wiring to `datafusion-datasource-avro`.

Repoint the feature-gated live decode arm to
`AvroSource::try_from_proto` and remove the old central encode arm. Keep
`try_into_avro_scan_physical_plan` as a deprecated compatibility wrapper
that delegates to the new implementation.

The protobuf wire format remains unchanged.

## Are these changes tested?

Yes. Added `roundtrip_avro_scan`.

## Are there any user-facing changes?

The existing `PhysicalPlanNodeExt` method remains available as a
deprecated compatibility wrapper. There is no immediate API removal or
wire-format change.

Subject: [PATCH 818/878] refactor(proto): migrate ArrowSource serde (#24189)

## Which issue does this PR close?

- Part of #23516.

## Rationale for this change

Part of epic #23494. Moves `ArrowSource` protobuf serialization from the
central dispatch into the source implementation.

## What changes are included in this PR?

Add protobuf serialization and deserialization to `ArrowSource` and add
the required `proto` feature wiring to `datafusion-datasource-arrow`.

Repoint the live decode arm to `ArrowSource::try_from_proto` and remove
the old central encode arm. Keep `try_into_arrow_scan_physical_plan` as
a deprecated compatibility wrapper that delegates to the new
implementation.

The protobuf wire format remains unchanged.

## Are these changes tested?

Yes. The existing `roundtrip_arrow_scan` coverage passes through the new
hooks.

## Are there any user-facing changes?

The existing `PhysicalPlanNodeExt` method remains available as a
deprecated compatibility wrapper. There is no immediate API removal or
wire-format change.

Subject: [PATCH 819/878] chore(proto): deprecate `AsyncFuncExec::async_exprs`,
 which only existed for proto serialization (#24168)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Follow-up cleanup for the proto hook migration EPIC #23494. Does not
close it.

## Rationale for this change

Five public accessor methods on physical plan nodes exist for one reason
only: an older protobuf serialization PR needed to reach a private
struct field from outside the plan's own module. Each was introduced by
the serialization PR that needed it, and none was ever part of an API
anyone asked for.

Now that every one of these plans serializes itself through its own
`try_to_proto` hook — which lives in the same module and can read the
fields directly — the accessors have no callers inside DataFusion.

But "no caller inside DataFusion" is not the same as "no caller". Of the
five, **only one is deprecated** — the other four all turned out to have
a real, non-serialization consumer downstream:

| Method | Introduced by | Callers in DataFusion | Known downstream
caller | This PR |
| --- | --- | --- | --- | --- |
| `AsyncFuncExec::async_exprs` | "[Proto]: Serialization support for
`AsyncFuncExec`" (#19118) | none | none found | **deprecated** |
| `AnalyzeExec::verbose` | "Implement protobuf serialization for
AnalyzeExec" (#7574) | none | datafusion-distributed, openobserve | kept
as-is |
| `AnalyzeExec::show_statistics` | "Implement protobuf serialization for
AnalyzeExec" (#7574) | none | openobserve | kept as-is |
| `UnnestExec::list_column_indices` | "Support encoding and decoding
UnnestExec" (#12344) | none | goldsky streamling | kept as-is |
| `UnnestExec::struct_column_indices` | "Support encoding and decoding
UnnestExec" (#12344) | none | goldsky streamling | kept as-is |

An earlier revision of this PR deprecated four of the five.
@kumarUjjawal's
[review](https://github.com/apache/datafusion/pull/24168#pullrequestreview-4891479842)
pointed at two downstream projects I had not checked, which between them
use three of those four. Those three deprecations have been reverted;
see [below](#downstream-usage-check).

Every one of the four kept accessors is the same shape: downstream code
downcasts a planned node and needs to read its private fields in order
to rebuild it as its own node. That is a legitimate use, and the fact
that an accessor was *originally added* for proto doesn't make its
current use wrong. Deprecating them would push a warning onto downstream
projects for an API they have a real need for, with nothing to point
them at instead.

## What changes are included in this PR?

Adds `#[deprecated(since = "55.0.0", note = "...")]` to
`AsyncFuncExec::async_exprs`. Nothing is removed, no behavior changes,
and the other four accessors are untouched.

The `note` is honest that there is no replacement: `AsyncFuncExec`
serializes itself through `AsyncFuncExec::try_to_proto`, which reads the
field directly, so there is nothing to point users at. It follows the
existing phrasing used by the deprecated shims in
`datafusion/proto/src/physical_plan/mod.rs` ("unused by DataFusion;
...") combined with the repo's established no-replacement idiom ("please
open an issue if you have a use case for it").

`AsyncFuncExec::async_exprs` already had zero callers before #24166; its
`try_to_proto` hook was written against the field from the start.

## Are these changes tested?

There is no new behavior to test — the real verification is that the
compiler agrees the method is unused. Since `deprecated` is a warning
and CI builds with `-D warnings`, a clean lint over the whole workspace
*is* the proof that no internal caller remains.

Run locally on this branch:

- `cargo fmt --all`
- `cargo clippy --all-targets --workspace --features
avro,integration-tests,extended_tests -- -D warnings` (CI's exact
invocation) — clean across every crate, including `datafusion-cli`,
`benchmarks`, `datafusion-examples` and `substrait`
- `cargo test -p datafusion-proto --test proto_integration` — 219
passed, 0 failed
- `cargo test -p datafusion-physical-plan` — passed, 0 failed

## Downstream usage check

Before deprecating, I checked the three main downstream consumers at
their current `main` (2026-08-09), by cloning each repo and grepping for
all five accessor names plus every mention of `AnalyzeExec` /
`UnnestExec` / `AsyncFuncExec`. GitHub code search returned 503s and
silent empty results at the time, which is exactly why the survey missed
two projects — @kumarUjjawal caught both in review.

| Repo | Uses any of the five? | Which |
| --- | --- | --- |
|
[datafusion-distributed](https://github.com/datafusion-contrib/datafusion-distributed)
(`45bd823`) | Yes | `AnalyzeExec::verbose` |
| [openobserve](https://github.com/openobserve/openobserve) (`575e8ea`)
| Yes | `AnalyzeExec::verbose`, `AnalyzeExec::show_statistics` |
| [goldsky streamling](https://github.com/goldsky-io/streamling)
(`8d85af9`) | Yes | `UnnestExec::list_column_indices`,
`UnnestExec::struct_column_indices` |
| [datafusion-comet](https://github.com/apache/datafusion-comet)
(`c706360`) | No | — |
| [datafusion-ballista](https://github.com/apache/datafusion-ballista)
(`06f8f1d`) | No | — |

**datafusion-distributed — `verbose`.** `src/explain_analyze.rs:34`
builds a `DistributedAnalyzeExec` from `analyze_exec.verbose()`, driven
by a planner that downcasts a planned `AnalyzeExec`
(`src/distributed_planner/distributed_query_planner.rs:96`). It does not
read `show_statistics` — `DistributedAnalyzeExec` doesn't carry that
flag.

**openobserve — `verbose` *and* `show_statistics`.**
[`src/search/src/datafusion/optimizer/physical_optimizer/distribute_analyze.rs:31-37`](https://github.com/openobserve/openobserve/blob/575e8ea4d5fd4b0e630aa013a1a31b1da56708e9/src/search/src/datafusion/optimizer/physical_optimizer/distribute_analyze.rs#L31-L37)
does the same rewrite as datafusion-distributed, but reads both flags:

```rust
if let Some(analyze) = plan.downcast_ref::<AnalyzeExec>() {
    let distribute_analyze = Arc::new(DistributeAnalyzeExec::new(
        analyze.verbose(),
        analyze.show_statistics(),
        analyze.input().clone(),
    )) as Arc<dyn ExecutionPlan>;
```

**goldsky streamling — both unnest accessors.**
[`crates/streamling-core/src/operators/unnest.rs:85-99`](https://github.com/goldsky-io/streamling/blob/8d85af926b034085aece04233722c508ac80f2d0/crates/streamling-core/src/operators/unnest.rs#L85-L99),
in `StreamingUnnestExec::from_original`, rebuilds a DataFusion
`UnnestExec` as its own streaming operator and reads both index lists to
do it:

```rust
let list_column_indices = original_unnest
    .list_column_indices()
    .iter()
    .map(|idx| ListUnnest { index_in_input_schema: idx.index_in_input_schema, depth: idx.depth })
    .collect();
let struct_column_indices = original_unnest.struct_column_indices().to_vec();
```

**datafusion-comet — no usage.** It constructs `UnnestExec::new(...)` in
`native/core/src/execution/planner.rs:2081` but never reads the index
lists back out. Zero hits for any of the five names.

**datafusion-ballista — no usage.** Two near-misses, both false
positives: `ballista/core/src/planner.rs:148` reads `analyze.verbose`,
but that is the public field on the **logical** `LogicalPlan::Analyze`
node, not the physical accessor;
`ballista/scheduler/src/state/distributed_explain.rs:155` calls
`UnnestExec::new(...)`, construction only.

**`AsyncFuncExec::async_exprs`.** Code search for `async_exprs` and for
the literal `async_exprs()` across public Rust code returns hits only in
DataFusion itself and in forks/vendored copies of it
(`ClickHouse/rust_vendor`, `apache/datafusion-sandbox`,
`Epsio-Labs/hiring-datafusion`, `smartdu/datafusion`). The three
non-fork repos that mention `AsyncFuncExec` — `apache/sedona-db`,
`influxdata/datafusion-udf-wasm`, `goldmedal/datafusion-llm-function` —
have no calls to the accessor.

This still covers only what public code search and these five projects
show. If you know of a consumer of `AsyncFuncExec::async_exprs`, say so
and I'll drop the last deprecation too, on the same reasoning applied to
the other four.

## Are there any user-facing changes?

Yes, and the `api change` label applies.

Downstream users who call `AsyncFuncExec::async_exprs` will now see a
deprecation warning. Nothing breaks in this release — the method still
works exactly as before. Removal follows the normal deprecation window
described in the [API health
policy](https://github.com/apache/datafusion/blob/main/docs/source/contributor-guide/api-health.md)
(six major versions or six months, whichever is longer), consistent with
the plan in EPIC #23494.

`AnalyzeExec::verbose`, `AnalyzeExec::show_statistics`,
`UnnestExec::list_column_indices` and
`UnnestExec::struct_column_indices` are unchanged, so
datafusion-distributed, openobserve and goldsky streamling see no new
warning.

There is intentionally no replacement API for `async_exprs`. If you have
a use case for reading that field from outside the plan, please open an
issue — that is a real API request worth designing deliberately, rather
than something to leave standing by accident.

Subject: [PATCH 820/878] fix: return error instead of panic when decoding
 ParquetScan/AvroScan without features (#24198)

## Which issue does this PR close?

- Closes #24197.

## Rationale for this change

Explained in #24197.

## What changes are included in this PR?

I just replaced the three feature-gate `panic!`s in
`datafusion/proto/src/physical_plan/mod.rs` with `not_impl_err!`,
following the existing `ParquetSink` convention in the same file. Also
fixes "a Avro" to "an Avro" in the message.

## Are these changes tested?

Checked the same feature combinations as the `datafusion-proto features`
CI job and ran `cargo test -p datafusion-proto`. Manually verified with
a no-default-features build that decoding panicked before and returns
`NotImplemented` after. No regression test added because the error path
only exists in feature-disabled builds, which CI only runs `cargo check`
on.

## Are there any user-facing changes?

No API changes.

Subject: [PATCH 822/878] fix: re-enable null-equal join dynamic filters with
 an IS NULL predicate (#23106)

## Which issue does this close?

Re-enables the dynamic filter that #22965 disabled (#22964), with the
proper null-equal semantics.

## Rationale for this change

#22965 disabled hash-join dynamic filter pushdown for null-equal joins:
the build-side bounds and membership predicates evaluate to NULL for a
probe-side NULL key, so they prune rows that should null-match a
build-side NULL. Its description already named the better fix, "generate
a predicate with `OR IS NULL`". #23104 does that for null-aware anti
joins; this re-enables the null-equal case the same way.

## What changes are included in this PR?

- Revert the null-equal `return false` in
`allow_join_dynamic_filter_pushdown`.
- Generalize the shared probe-NULL helper to cover both null-aware
(single-key) and null-equal (multi-key) joins: OR `key IS NULL` for
every nullable probe key. A NOT NULL key never widens the filter, so an
all-NOT-NULL join keeps full selectivity.

## Are these changes tested?

Yes. #22965's SLT now asserts the filter is back on the probe with the
result unchanged, plus a multi-key null-equal case. The reject unit test
flips to assert pushdown is allowed, and `preserve_probe_nulls` unit
tests cover both the mixed nullable/NOT NULL case (only the nullable key
widens) and the all-NOT-NULL case (no widening).

## Are there any user-facing changes?

Null-equal joins regain dynamic filter pushdown, so they prune the probe
scan again while returning correct results.

Subject: [PATCH 825/878] fix(physical-plan): count empty grouping sets in the
 aggregate row estimate for an empty input (#24039)

## Which issue does this PR close?

- Closes #24038.
- Part of #8227.

## Rationale for this change

`AggregateExec` reported a row count of `Exact(0)` whenever its input
had no rows, even when the
group-by contained an empty grouping set. `GROUPING SETS(())`, `ROLLUP`
and `CUBE` each emit a
grand-total row for such an input, so the row count contradicted
execution. The count was claimed
as `Exact`, so rules that answer a query from statistics rather than by
executing it returned a
value that no row of the result holds:

```sql
SELECT COUNT(*) FROM (SELECT SUM(v1) FROM t WHERE false GROUP BY ROLLUP(v1));
-- 0, while the inner aggregate emits one row
```

This is a correctness fix, not an estimation improvement.

## What changes are included in this PR?

- `estimate_num_rows` counts the empty grouping sets instead of reusing
the child's row count of
zero. Partial aggregation emits the grand-total row from every output
partition, so the count
goes through the per-partition scaling already applied to aggregates
without grouping
  expressions, now factored into `scale_logical_rows`.
- The grouping columns of such an output are reported as NULL: typed
null bounds, a distinct
  count of zero, and a null count equal to the row count.

## Are these changes tested?

Yes.

- SQL logic tests in `grouping.slt` for both folds: an outer `COUNT(*)`
over `ROLLUP`, `CUBE` and
  `GROUPING SETS`, and an outer `MIN`/`MAX` over the grand-total row.
- Unit tests for the reported statistics: zero rows for a plain `GROUP
BY`, one row for
`GROUPING SETS((a), ())`, two rows for `GROUPING SETS((a), (), ())`, the
partition scaling of a
  partial aggregate, and the NULL grouping-column statistics.

Each test was checked to fail without the corresponding change.

## Are there any user-facing changes?

Yes. Queries such as the one above now return the correct result. There
are no API changes.

Subject: [PATCH 826/878] fix: generate_series overflow panics at i64 boundary
 and out-of-range dates (#23723)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #22208
- Closes #22193

Supersedes #22250 (closed unmerged by its author on 2026-06-04 after the
approach was approved). Note: both issues are currently assigned to
@xiedeyantu (idle since 2026-05; #22193 was explicitly blocked on
#22250). I've left a note on both issues; happy to coordinate if the
assignee has work in progress.

## Rationale for this change

Two overflow bugs in the `generate_series` / `range` table functions,
both panicking in debug builds and silently wrapping in release:

1. **#22208** — integer series: `SELECT * FROM
generate_series(9223372036854775806, 9223372036854775807, 2)` panics
with `attempt to add with overflow` when advancing past `i64::MAX`.
PostgreSQL and DuckDB both return one row (`9223372036854775806`),
stopping after the last reachable value.
2. **#22193** — date series: converting `Date32` days to timestamp
nanoseconds uses an unchecked multiplication, so `generate_series(DATE
'0001-01-01', ...)` panics at planning time. Dates outside the
nanosecond timestamp range (1677-09-21 – 2262-04-11) cannot be
represented and must error cleanly instead.

## What changes are included in this PR?

- `datafusion/functions-table/src/generate_series.rs`
- `SeriesValue::advance` now takes `end: &mut Self`; the `i64`
implementation uses `checked_add` and, on overflow, clamps `end` so the
series terminates after the last reachable value (the approach approved
in #22250). The per-batch loop stops right after emitting the final
value. `TimestampValue::advance` already errors on out-of-range interval
addition and is unchanged apart from the signature.
- The Date32→nanoseconds conversion uses `checked_mul` and returns a
planning error naming the offending argument.
- `datafusion/sqllogictest/test_files/table_functions.slt`
- Regression cases: positive/negative step overflow, landing exactly on
`i64::MAX`, `range` (end-exclusive) overflow, and first/second date
argument out of range.

## Are these changes tested?

Yes:
- New sqllogictest cases (exact reproducers from both issues, plus
boundary variants); verified the integer-case outputs match
PostgreSQL/DuckDB.
- Verified `cargo fmt`, workspace clippy
(`avro,integration-tests,extended_tests`, `-D warnings`), `cargo test -p
datafusion-functions-table`, and the extended workspace suite (ci
profile with
`avro,json,backtrace,extended_tests,recursive_protection,parquet_encryption`)
— all green.

## Are there any user-facing changes?

Only the bug fixes: integer series near `i64::MAX`/`MIN` now return the
reachable values instead of panicking or wrapping (matching
PostgreSQL/DuckDB), and out-of-range dates produce a planning error
instead of a panic. No API changes.

This change does not close the above issues because it does not
implement a way to tell if a node is a producer dynamic filters.

## Rationale for this change

See https://github.com/apache/datafusion/issues/23814 and
https://github.com/datafusion-contrib/datafusion-distributed/pull/553.

To send dynamic filter updates across the network, there needs to be a
way to get access to `PhysicalExpr` from `ExecutionPlan`. As discussed
in https://github.com/apache/datafusion/issues/23814, the cleanest way
to do this is to add `ExecutionPlan::apply_expressions`, which mirrors a
similar method for logical plan nodes.

## What changes are included in this PR?

There's 3 commits in this PR:

Firstly, commit 1 re-applies the changes in
https://github.com/apache/datafusion/pull/20337 (reverted in
https://github.com/apache/datafusion/pull/22437).

Some of the reasons for why the original PR was reverted include
(a) `apply_expressions` is too complicated to implement and there's no
concrete need to justify this complexity
(b) there was no usage of `apply_expressions` inside this repo

To address (a)
- justification for adding this method is provided in
https://github.com/apache/datafusion/issues/23814
- commit 2 in this PR adds helper methods `apply_expression_roots` and
`apply_no_expressions` which abstract away the `TreeNodeRecursion`
complexity from implementors. Now, `apply_expressions` very trivial to
implement ex.
```rust
fn apply_expressions(
    &self,
    f: &mut dyn FnMut(&Arc<dyn PhysicalExpr>) -> Result<TreeNodeRecursion>,
) -> Result<TreeNodeRecursion> {
    apply_expression_roots([&self.predicate_1], f)
    apply_expression_roots([&self.predicate_2], f)
    apply_expression_roots([&self.other_expression], f)
}
```
- the method traverses over `&Arc<dyn PhysicalExpr>` rather than `&dyn
PhysicalExpr` to reduce complexity around lifetimes

To address (b):
- commit 3 adds a usage of `apply_expressions` in
`physical-plan/src/aggregates/mod.rs`. Previously, there was a hack that
checked if a filter was pushed down using `Arc::strong_count(dyn_filter)
> 1`. Now it uses `apply_expressions`
- similarly, commit 4 removes `is_used` from dynamic filters which used
to check Arc references counts to see if a filter was pushed down. Now,
the hash join uses `apply_expressions` to find pushed down filters.

## Are these changes tested?

Yes.

## Are there any user-facing changes?

There's a new mandatory method `ExecutionPlan::apply_expressions()`. See
the upgrading guide and documentation for details.

Subject: [PATCH 828/878] test(proto): add missing physical plan round-trip
 coverage (#24172)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #24171.

This addresses items (a), (b) and (c) of that issue. It does **not**
attempt (d) the colocated test tier or (e) splitting up
`roundtrip_physical_plan.rs`, both of which are larger and independent,
so the issue stays open.

Split out of #24167 at the reviewer's prompting: @andygrove pointed out
on that PR that the "covered by existing round-trip tests" claim did not
hold — there is no round-trip test for `SortPreservingMergeExec`. He was
right. Rather than bundle new tests with a mechanical refactor, they are
here on their own so the two can be reviewed and merged independently.

## Rationale for this change

`datafusion/proto/tests/cases/roundtrip_physical_plan.rs` is the safety
net for physical-plan serialization. A field that is silently dropped on
the wire produces a plan that still *runs* — it just returns different
rows. Checking turned up two real holes:

1. **`SortPreservingMergeExec` had no round-trip test at all.** The
string `SortPreservingMerge` did not appear anywhere in the file.
Nothing constructed one, so nothing on the encode or decode path for
that plan was exercised.

2. **`SortExec::fetch` is serialized but was never exercised.**
`roundtrip_sort` and `roundtrip_sort_preserve_partitioning` both leave
`fetch` as `None`, so the `Some(..)` state had no coverage. `fetch` is
what makes a `SortExec` a top-k sort; dropping it on the wire silently
widens the result set.

Both are cases where a serialization gap changes query results rather
than causing a visible failure.

## What changes are included in this PR?

Two new tests in `roundtrip_physical_plan.rs`. No production code
changes.

- **`roundtrip_sort_preserving_merge`** — covers everything actually on
the wire for `SortPreservingMergeExecNode`: the input, the sort
expressions, and `fetch` in both its `None` (encoded as `-1`) and
`Some(11)` states.
- **`roundtrip_sort_with_fetch`** — `SortExec` with `fetch: Some(7)`,
plus `fetch: Some(3)` combined with `preserve_partitioning: true`, since
both live in the same proto node.

### Which tests assert on accessors rather than the helper, and why

The file's `roundtrip_test` helper compares `format!("{plan:?}")` before
and after. That comparison is only as good as the plan's `Debug` impl —
it is blind to any field `Debug` does not print, which is how #24165
(`HashJoinExec::fetch`) survived.

`SortExec` and `SortPreservingMergeExec` both currently *derive*
`Debug`, so the helper does in fact observe `expr`, `fetch` and
`preserve_partitioning` today. I checked rather than assumed, and the
deliberate-break results below confirm it — the helper is what fires
first under each break.

But that coverage is incidental: it would vanish the day either plan
grows a hand-written `Debug`. So both new tests go through
`roundtrip_test_and_return`, downcast, and assert on `fetch()`,
`expr()`, `preserve_partitioning()` and the input schema directly, with
the helper's string comparison still running as a backstop.

### What is deliberately *not* asserted

`SortPreservingMergeExec::enable_round_robin_repartition` is **not**
serialized — `SortPreservingMergeExecNode` has only `input`, `expr` and
`fetch`, so decode always restores the `true` default from
`SortPreservingMergeExec::new`. A round-trip equality assertion would
pass whether or not that field were on the wire, so asserting on it
would advertise coverage that does not exist. The test carries a comment
saying so instead.

The same applies to `Global/LocalLimitExec::required_ordering`, which is
set by the `enforce_sorting` rule and starts as `None` on a decoded
plan.

If either field *should* be on the wire, that is a separate change with
a wire-format bump, not something to paper over with a test that cannot
tell the difference.

### Plans I checked and decided needed nothing

I went through the rest of the plans touched by #24167 looking for state
that is on the wire but exercised by no test. These already have
adequate coverage and I did not add to them:

| Plan | Existing coverage |
|---|---|
| `GlobalLimitExec` | `roundtrip_global_limit` (skip 0 / limit 25) and
`roundtrip_global_skip_no_limit` (skip 10 / limit `None`) — both `skip`
and `fetch` states |
| `LocalLimitExec` | `roundtrip_local_limit` |
| `FilterExec` | `roundtrip_filter_with_fetch` already asserts
`default_selectivity`, `batch_size` and `fetch` on the accessors;
`roundtrip_filter_projection_states` covers the projection |
| `ProjectionExec` | `roundtrip_projection_source`,
`roundtrip_empty_projection` |
| `RepartitionExec` | `roundtrip_repartition_preserve_order`
(round-robin + `preserve_order`), `roundtrip_range_partitioning`, plus
hash-partitioning cases |
| `UnionExec` / `InterleaveExec` | `roundtrip_union`,
`roundtrip_interleave` — nothing on the wire beyond the children |
| `CoalesceBatchesExec` | `roundtrip_coalesce_batches_with_fetch` covers
`target_batch_size` and `fetch` in both states |
| `CoalescePartitionsExec` | `roundtrip_coalesce_partitions_with_fetch`,
both `fetch` states |
| `CooperativeExec` | `roundtrip_cooperative` — only the input is on the
wire |
| `BufferExec` | `roundtrip_buffer` asserts `capacity()` on the accessor
|
| `EmptyExec` / `PlaceholderRowExec` |
`roundtrip_empty_with_partitions`,
`roundtrip_placeholder_row_with_partitions` |
| `ExplainExec` | `roundtrip_explain` asserts schema, stringified plans
and `verbose` on the accessors |
| `ScalarSubqueryExec` | `roundtrip_scalar_subquery_exec` and the
executing variant |

Per the issue, this is not a push for 100% field coverage. These two
were the cases where the gap was real and the test was cheap; past them
it got contrived fast.

## Are these changes tested?

This PR *is* tests. To confirm they are not vacuous, I broke the encode
side on purpose and checked each one fails:

| Deliberate break | Result |
|---|---|
| `SortPreservingMergeExec` encode: hardcode `fetch: -1` |
`roundtrip_sort_preserving_merge` **FAILS** |
| `SortPreservingMergeExec` encode: `.take(1)` on the sort expressions |
`roundtrip_sort_preserving_merge` **FAILS** |
| `SortExec` encode: hardcode `fetch: -1` | `roundtrip_sort_with_fetch`
**FAILS** |

Under all three breaks the pre-existing `roundtrip_sort` and
`roundtrip_sort_preserve_partitioning` kept passing — a direct
demonstration that the gap was real. All breaks reverted; the diff here
is test-only.

Checks run:

- `cargo fmt --all`
- `cargo clippy --all-targets --workspace --features
avro,integration-tests,extended_tests -- -D warnings` — clean
- `cargo test -p datafusion-proto --test proto_integration` — 216
passed, 0 failed (214 before this PR)
- `cargo test -p datafusion-physical-plan` — 1641 passed, 0 failed

### Why this is based on `main` rather than on #24167

These tests pass on unmodified `main` — verified, not assumed. They
describe serialization behaviour that already exists, and none of them
depends on #24167's changes.

That gives a useful property: merged first, they pin the current wire
behaviour independently, which makes #24167's "wire format unchanged"
claim something CI verifies rather than something the PR description
asserts.

## Are there any user-facing changes?

No. Test-only; no production code touched.

Subject: [PATCH 829/878] fix(proto): serialize Global/LocalLimitExec
 required_ordering (#24183)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #24173

## Rationale for this change

`GlobalLimitExec`/`LocalLimitExec` `required_ordering` is not
serialized, so a roundtrip loses the only record that a pushed-down
`LIMIT` is order-sensitive. Re-running `LimitPushdown` on the decoded
plan then sets `preserve_order: false` on the scan, which is free to
read files out of order — `ORDER BY ... LIMIT` can return the wrong
rows.

## What changes are included in this PR?

- Add `required_ordering` to `GlobalLimitExecNode` (field 4) and
`LocalLimitExecNode` (field 3); empty list means `None`
- New
`optional_ordering_try_to_proto`/`optional_ordering_try_from_proto`
helpers in `physical-expr-common`, also reused by
`SymmetricHashJoinExec` serde which hand-rolled the same pattern
- Preserve `required_ordering` in both execs' `with_new_children`
## Are these changes tested?
Yes new tests that would fail on main if not fixed

## Are there any user-facing changes?
No

Subject: [PATCH 830/878] Skip page index load (and `ParquetMetaData` clone)
 when the file has no page index (#24150)

## Which issue does this PR close?

- Part of #24149

## Rationale for this change

My prfiling on ClickBench Q24 in #24149 showed almost 10% of query time
spent cloning / dropping `ParquetMetaData`.

This appeared to be related to trying to load page index, which the
ClickBench files don't actually have

## What changes are included in this PR?

- Only attempt to load the page index (which requires cloning the
`ParquetMetaData`) when the file actually has infomration to load

## Are these changes tested?

Yes
## Are there any user-facing changes?

Yes -- better clickbench performance

Note it only really helps clickbench_1 because in that case the cost of
cloning ParquetMetadata is much higher (as it is a much larger structure
due to the larger file)

Subject: [PATCH 831/878] fix: clear stale sliding aggregate state for empty
 RANGE frames (#24185)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #24184.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.

Please explain the problem you are trying to solve in terms of the
user-visible
behavior, rather than the implementation.

For example, "The code in `foo.rs` doesn't handle nulls" is a symptom of
the
implementation. "COUNT(DISTINCT) returns wrong results when the column
contains
nulls" is the user-visible problem.
-->

Sliding aggregate window functions can return incorrect results when a
bounded `RANGE` frame transitions from non-empty to empty and then back
to non-empty.

The empty frame does not clear the previous accumulator state, so stale
values are included in subsequent results.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here, but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

- Retract the previous frame from the accumulator when the current frame
is empty.
- Add a slt covering

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

If there are any breaking changes to public APIs, please add the `api
change` label.
-->

Bug fix only.

Subject: [PATCH 832/878] test(proto): split roundtrip_physical_plan.rs by plan
 category (#24223)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`roundtrip_physical_plan.rs` had grown to 5,682 lines, so finding the
tests for a given plan — or noticing that a plan has none — meant
scrolling through every other plan's tests. #24171 (e) proposed
splitting it by plan category; this does that.

The tests now live in `tests/cases/plans/`, grouped by what they cover:
leaves, dispatch, limits, filters, joins, sorts, aggregates, windows,
sources, sinks, udfs, exprs, dynamic_filters, scalar_subquery, misc and
tpch. The shared round-trip helpers (`roundtrip_test` and friends) stay
in `plans/mod.rs`; every other item moved into exactly one file, and
each file carries its own imports rather than inheriting one 140-line
block.

Pure code motion: no test was added, removed, renamed or edited. Every
moved item is byte-identical to its previous form, and the test
inventory (`--list`) is unchanged at 222 entries.

Subject: [PATCH 833/878] perf: optimize char -> byte offset mapping in
 `regexp_count` (#24153)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- N/A

## Rationale for this change

`regexp_count` takes an optional argument, `start`, that specifies a
character-based position. The current implementation involves calling
`start.chars().count` for every input row, which scans the entire
string. This is unnecessarily expensive for the common case that `start`
identifies a character position near the start of the string: once we've
converted `start` into a byte offset, we can stop scanning the rest of
the string.

Fix this by doing a lazy walk of the string and stopping early. This was
first done for `regexp_instr` in #24054; this PR refactors that code
into a shared helper. In passing, this also fixes a 32-bit portability
bug with the previous code in `regexp_count` as well.

regexp_count benchmark, with_start cases:

- `size=1024 str_len=32`:  -5.7%
- `size=1024 str_len=128`: -11.5%
- `size=4096 str_len=32`:  -4.1%
- `size=4096 str_len=128`: -6.6%

## What changes are included in this PR?

* Refactor char position -> byte offset mapping from `regexp_instr` into
a new helper, `start_to_byte_offset`
* Use `start_to_byte_offset` in both `regexp_instr` (no functional
change) and `regexp_count`
* Add SLT cases verifying that `regexp_count` handles zero-width
patterns the same way that PostgreSQL does (this was the primary
motivation for #24054)

## Are these changes tested?

Yes — new unit tests for the shared helper; new SLT cases pin the
existing zero-width-pattern behavior of the refactored path (verified
against PostgreSQL 18.4); existing `regexp_instr`/`regexp_count` tests
cover the rest.

## Are there any user-facing changes?

No.

Subject: [PATCH 834/878] fix(proto): preserve AggregateExec schema and
 reversed state (#24207)

## Which issue does this PR close?

- Closes #24202.

## Rationale for this change

Physical-plan deserialization rebuilt `AggregateExec` output schemas
from decoded aggregate expression names. `OptimizeAggregateOrder` can
reverse aggregate expressions while preserving the original schema,
causing protobuf round trips to change output field names and lose the
expression's reversed state.

## What changes are included in this PR?

- Serialize and restore the preserved `AggregateExec` output schema.
- Serialize and restore `AggregateFunctionExpr::is_reversed`.
- Fall back to schema reconstruction for older payloads without an
output schema.
- Regenerate the prost and pbjson models.
- Add a byte-level regression test covering optimizer reversal and
backward compatibility.

## Are these changes tested?

Yes:

- `cargo test -p datafusion-proto --test proto_integration
roundtrip_aggregate_preserves_optimizer_schema_and_reversed_state`
- `cargo fmt --all`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `./dev/rust_lint.sh`

## Are there any user-facing changes?

Physical-plan protobuf round trips now preserve aggregate output field
names and reversed state. The protobuf wire format remains backward
compatible; generated Rust model structs gain new fields.

Subject: [PATCH 835/878] physical-plan: coerce UNION/INTERLEAVE schema
 mismatches at plan time (#24094)

## Which issue does this PR close?

Follow-up to #23861 (issue #15394). Not closing a new issue.

## Rationale for this change

#23861 fixed `UNION ALL` batches carrying the wrong nullability when one
leg
is `NOT NULL` and another isn't, by re-stamping each batch's schema
inside
`UnionExec`/`InterleaveExec`'s own `execute()`. In review, @alamb noted:

> ideally we could coerce the schema at plan time but I don't know how
to
> coerce nullability

This PR does that: the coercion becomes an explicit node in the plan
tree,
inserted when the plan is built, instead of invisible logic inside
`execute()`.

## What changes are included in this PR?

- Adds `CoerceSchemaExec`, a single-child passthrough `ExecutionPlan`
node.
`UnionExec::try_new`/`InterleaveExec::try_new` insert it above any child
  whose own output schema disagrees with the computed union schema (in
practice, only nullability differs -- `UnionExec::try_new` already
rejects
  real data-type mismatches via `calculate_union`).
- The actual batch re-stamping logic (`SchemaConformingStream`) is
unchanged;
  it just lives under `CoerceSchemaExec::execute()` now instead of being
  called directly from `UnionExec`/`InterleaveExec::execute()`.
- Because it's a real plan node, `CoerceSchemaExec` implements the full
`ExecutionPlan` surface a pure 1:1 passthrough needs to stay transparent
  to the optimizer: statistics passthrough, filter/limit pushdown,
  `benefits_from_input_partitioning() -> false` (so it doesn't trigger a
  spurious repartition), and proto (de)serialization -- the node erases
  itself on encode and is reconstructed by `try_new` on decode, so no
  protobuf schema change was needed.
- A genuine data-type mismatch (as opposed to nullability-only) is now
  rejected eagerly at plan-build time (via `EquivalenceProperties::
  with_new_schema`) rather than lazily at `execute()`.

## Are these changes tested?

- New unit test
`test_union_partition_statistics_with_mismatched_nullability`
in `union.rs`, proving statistics aren't poisoned to `Absent` through
the
  new node.
- Existing `union_nullable`/`union_nullable_spill` regression tests from
  #23861 continue to pass unchanged.
- Updated the `sqllogictest` golden file (`union.slt`) where `EXPLAIN`
  output now shows the new node for pre-existing nullability-mismatched
  `UNION ALL` cases.
- Benchmarked against the previous (inline) approach: no measurable
  performance difference in either the coerced or matched-schema case
  (differences were within run-to-run noise).

## Are there any user-facing changes?

`EXPLAIN` output for a `UNION ALL`/interleaved plan with a nullability
mismatch across legs will now show a `CoerceSchemaExec` node that wasn't
there before. No behavioral or correctness change.

Subject: [PATCH 836/878] fix(parquet): remap sorting columns for partitioned
 writes (#24211)

## Which issue does this PR close?

- Closes #24210.

## Rationale for this change

When Hive partition columns are not kept in Parquet files,
`FileSinkConfig::output_schema()` still describes the sink input while
`get_writer_schema(&conf)` removes those partition columns.
`ParquetFormat::create_writer_physical_plan` currently converts the
input ordering directly to Parquet `sorting_columns`, so its column
indices can reference removed columns or the wrong positions in the
written schema. Reading that metadata can then panic in
`SchemaDescriptor::column` with an out-of-bounds index.

The execution ordering and the Parquet footer ordering have different
schema domains: `DataSinkExec` must retain the original input ordering,
while `ParquetSink` metadata must use indices from the actual writer
schema.

## What changes are included in this PR?

- Derive Parquet `sorting_columns` from both the input schema and
`get_writer_schema(&conf)`.
- Omit ordering keys that are removed from the written file, such as
Hive partition columns.
- Remap retained ordering keys to their writer-schema indices while
preserving sort direction and null ordering.
- Keep the original `order_requirements` unchanged for `DataSinkExec`.
- Avoid writing an empty `sorting_columns` list when every ordering key
is removed.
- Add unit and end-to-end regression coverage for partitioned Parquet
writes.

## Are these changes tested?

Yes. The new tests cover the writer-schema remapping directly and verify
the resulting Parquet footer after a partitioned write.

## Are there any user-facing changes?

There are no public API changes. Newly written partitioned Parquet files
now contain valid `sorting_columns` metadata based on their physical
file schema. Existing files with invalid metadata are unchanged and must
be rewritten separately.

Subject: [PATCH 837/878] feat(dataframe): add f16 support to dataframe! macro
 (#24234)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes https://github.com/apache/datafusion/issues/24232.

## Rationale for this change
The `dataframe!` macro supports most primitive numeric types but was
missing `f16` support. This change addresses the existing `TODO` and
adds support for `f16` values.
<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.

Please explain the problem you are trying to solve in terms of the
user-visible
behavior, rather than the implementation.

For example, "The code in `foo.rs` doesn't handle nulls" is a symptom of
the
implementation. "COUNT(DISTINCT) returns wrong results when the column
contains
nulls" is the user-visible problem.
-->

## What changes are included in this PR?
- Add `IntoArrayRef` implementations for `half::f16`:
  - `Vec<half::f16>`
  - `Vec<Option<half::f16>>`
  - `&[half::f16]`
  - `&[Option<half::f16>]`

- Improve `test_dataframe_macro` to cover all supported primitive types
and the different input forms supported by the macro.
- Improve `test_dataframe_from_columns` to cover the supported Arrow
data types, including `Float16`.
- No breaking changes.
<!--
There is no need to duplicate the description in the issue here, but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?
Yes. The existing `test_dataframe_macro` and
`test_dataframe_from_columns` tests have been extended to verify the
expected data types and resulting dataframe contents.
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

## Are there any user-facing changes?
Yes. The `dataframe!` macro now supports `f16` values.
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

If there are any breaking changes to public APIs, please add the `api
change` label.

+/// # Inputs
+///
+/// - `file_schema` — the full file schema; provides the source `Field`s

+/// - `regular_indices` — file-schema column indices the filter references

+///   in their entirety). Must be sorted, deduplicated.
+/// - `access_tree` — the trie of nested struct field accesses recorded by
+///   [`PushdownChecker`].
+///
+/// # Behavior
 ///
-/// For regular (non-struct) columns, the full field type is used.
-/// For struct columns accessed via `get_field`, a pruned struct type is created
-/// containing only the fields along the access path. Note: it must match the schema
-/// that the Parquet reader produces when projecting specific struct leaves
+/// The set of columns to include is the union of `regular_indices` and
+/// `access_tree.roots.keys()`. For each column index in that union, decide
+/// how the field appears in the output:
+///
+/// 1. **Whole-column reference** (`idx` is in `regular_indices`). Keep the
+///    field's full type unchanged. This is the **whole-root override**:
+///    pruning is only valid when a column is accessed *exclusively* through
+///    nested field accesses; if any predicate references the whole column,
+///    the projected schema must preserve the full type for that column.
+///
+/// 2. **Nested-access-only struct root.** Look up the column's node in the
+///    access tree and call [`prune_struct_type`] on the field's `DataType`
+///    with that node. Wrap the pruned type in a new `Field` carrying the
+///    original name and nullability.
+///
+/// Column order in the output schema follows ascending file-schema index
+/// (via the `BTreeSet` union), matching the order the Parquet reader
+/// produces when projecting these columns.

Subject: [PATCH 839/878] fix: reject max_buffered_batches_per_output_file
 values below 2 (#24204)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of https://github.com/apache/datafusion/issues/17498

## Rationale for this change

```
DataFusion CLI v54.1.0
> set datafusion.execution.max_buffered_batches_per_output_file = 1;
> COPY (SELECT 1 as a) TO '/tmp/x.parquet';

thread 'tokio-rt-worker' panicked at datafusion/datasource/src/write/demux.rs:287:30:
mpsc bounded channel requires buffer > 0
```

Two call sites (`demux.rs::create_new_file_stream`,
`orchestration.rs::spawn_writer_tasks_and_join`) divide
`max_buffered_batches_per_output_file` in half to size a bounded `mpsc`
channel's capacity. Integer division rounds both 0 *and* 1 down to 0,
and Tokio's `mpsc::channel` panics on a zero capacity. A plain non-zero
check (like the existing `ConfigNonZeroUsize`) would not have been
sufficient here, since 1 also triggers the panic.

A third call site (`demux.rs::hive_style_partitions_demuxer`) uses the
raw value directly without dividing, so it would panic on 0 alone.

## What changes are included in this PR?

Adds `ConfigMinTwoUsize`, mirroring the existing `ConfigNonZeroUsize`
pattern already used for sibling fields (`batch_size`,
`meta_fetch_concurrency`, `minimum_parallel_output_files`, etc.), and
applies it to `max_buffered_batches_per_output_file`. Invalid values are
now rejected with a clear configuration error at set-time instead of
panicking later at write time. Updated the three read sites to call
`.get()`, updated the field doc comment to explain the constraint, and
regenerated `docs/source/user-guide/configs.md` via
`dev/update_config_docs.sh`.

## Are these changes tested?

Yes. Added two `statement error` cases to
`datafusion/sqllogictest/test_files/set_variable.slt` (values 0 and 1),
following the exact pattern already used for the sibling
`ConfigNonZeroUsize` fields in that file. Verified manually with
`datafusion-cli` that 0 and 1 now return a clean error instead of
panicking, and that 2 (the default) and 3 still work correctly. Ran
`cargo test -p datafusion-datasource --lib` (178 passed), the
`set_variable.slt` sqllogictest suite, and `cargo check --workspace
--all-targets` — all clean.

## Are there any user-facing changes?

Yes: setting `datafusion.execution.max_buffered_batches_per_output_file`
to `0` or `1` now returns a configuration error instead of panicking. No
change for any value `>= 2` (including the default of 2).

+datafusion.execution.max_buffered_batches_per_output_file 2 This is the maximum number of RecordBatches buffered for each output file being worked. Higher values can potentially give faster write performance at the cost of higher peak memory consumption. This budget is split evenly between two independent points in the write pipeline (see the demuxer diagram in #7791): how many files can be in flight from the demuxer to a writer task, and how many RecordBatches are buffered for a single file's writer. Must be at least 2 so each half gets at least 1 unit of buffering - 0 or 1 would leave one side with a zero-capacity channel and panic at write time.
 datafusion.execution.max_spill_file_size_bytes 134217728 Maximum size in bytes for individual spill files before rotating to a new file. When operators spill data to disk (e.g., RepartitionExec), they write multiple batches to the same file until this size limit is reached, then rotate to a new file. This reduces syscall overhead compared to one-file-per-batch while preventing files from growing too large. A larger value reduces file creation overhead but may hold more disk space. A smaller value creates more files but allows finer-grained space reclamation as files can be deleted once fully consumed. Now only `RepartitionExec` supports this spill file rotation feature, other spilling operators may create spill files larger than the limit. Default: 128 MB
 datafusion.execution.meta_fetch_concurrency 32 Number of files to read in parallel when inferring schema and statistics
 datafusion.execution.minimum_parallel_output_files 4 Guarantees a minimum level of output files running in parallel. RecordBatches will be distributed in round robin fashion to each parallel writer. Each writer is closed and a new file opened once soft_max_rows_per_output_file is reached.

Subject: [PATCH 840/878] Fix aggregate accumulator capacity accounting
 (#24099)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

* Part of #23393

## Rationale for this change

Two aggregate accumulators underreport owned memory in their `size()`
implementations:

* `CountGroupsAccumulator` calculates vector backing storage using the
wrong element type.
* `SlidingDistinctSumAccumulator` reports only the accumulator struct
size and omits its owned hash map allocation.

This change corrects those capacity-based estimates while preserving the
different `Accumulator::size()` and `GroupsAccumulator::size()`
self-inclusion contracts.

## What changes are included in this PR?

* Add `vec_capacity_bytes` to calculate a vector’s backing allocation
using its actual element type.
* Update `CountGroupsAccumulator::size()` to report the capacity-based
allocation of its counts vector while remaining self-excluded.
* Update `SlidingDistinctSumAccumulator::size()` to include
`size_of_val(self)` and an estimate of its hash map’s allocated entry
capacity.
* Document that the hash map estimate excludes implementation-specific
control bytes.

## Are these changes tested?

Yes. This PR adds the following unit tests:

* `count_groups_size_includes_vec_capacity`
* `vec_capacity_bytes_uses_element_type`
* `sliding_distinct_sum_size_includes_hash_map_capacity`

The tests verify that:

* grouped count size grows when vector backing storage is allocated;
* vector capacity accounting uses the vector’s element type;
* sliding distinct-sum size includes hash map capacity, grows after the
map expands, and continues to reflect retained capacity after entries
are retracted.

## Are there any user-facing changes?

No user-facing API or aggregate result changes are intended. This PR
only corrects internal memory-size estimates used for aggregate
accounting.

## LLM-generated code disclosure

This PR includes LLM-generated code and comments. All LLM-generated
content has been manually reviewed.

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes https://github.com/apache/datafusion/issues/24058

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.

-->

`format_decimal` and `format_float` had duplicated logic, and it'd be
easy to modify one function and forget to change the other, causing
bugs. This PR forces one source of truth for that logic.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here, but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Created a new helper.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes,

```
cargo t -p datafusion-spark format_string --lib
```

passes.

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

If there are any breaking changes to public APIs, please add the `api
change` label.
-->

No user facing-changes.

## Which issue does this PR close?

- part of #7013
- related to #22963

## Rationale for this change

@wyattwenzel is running a great set of community show cases about what
people are doing with DataFusion (see #22963). I think these talks are a
great way for people to understand what can be done with DataFusion.

Also, in general the more we tell people about DataFusion the better.
Also, making it easier to find DataFusion related content makes it more
likely people (and maybe agents) will be able to find it when needed

Subject: [PATCH 843/878] docs: explain Parquet content-defined chunking
 (#24155)

## Which issue does this PR close?

- Closes #21404.

## Rationale for this change

Parquet content-defined chunking is available as an experimental writer
feature, but the user documentation does not explain when it is useful
or how to configure it.

Users need to understand that CDC benefits storage or transfer systems
that reuse duplicate byte ranges, does not perform deduplication itself,
and requires the sequential writer path for each output file.

## What changes are included in this PR?

- Add a user guide explaining Parquet content-defined chunking from a
user perspective.
- Describe appropriate use cases, storage requirements, limitations, and
the sequential-writer tradeoff.
- Explain how directory output distributes batches across files and why
stable input ordering and file layout improve deduplication.
- Provide single-file SQL and Rust examples, session-level
configuration, defaults, and tuning guidance.
- Add the CDC writer options to the Parquet format-options reference.
- Add the guide to the documentation index near the advanced user
guides.

## Are these changes tested?

No test code is changed because this is a documentation-only update.

The documented behavior and examples were verified with:

- `cargo test --profile=ci --test sqllogictests -- parquet_cdc.slt`
- `cargo fmt --all -- --check`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `./ci/scripts/doc_prettier_check.sh`
- `git diff --check`

## Are there any user-facing changes?

Yes. This adds user-facing documentation for the existing experimental
Parquet CDC feature. It does not change runtime behavior or public APIs.

+# Parquet Content-Defined Chunking
+
+Content-defined chunking (CDC) is an experimental Parquet writer feature that
+makes data page boundaries depend on column values rather than fixed row or byte
+counts. This makes unchanged regions more likely to produce identical pages when
+closely related versions of a dataset are written with the same settings.
+
+CDC is useful when the resulting files are stored or transferred through a
+content-addressable or block-deduplicating system. Such a system can reuse the
+identical pages instead of storing or transferring them again. For example, a
+small insertion near the beginning of a dataset can change one page while later
+page boundaries converge back to those of the previous version.
+
+CDC does not itself deduplicate data or provide a page store. On a conventional
+filesystem or object store, each Parquet file is still stored in full. The output
+is a normal Parquet file and requires no CDC-specific reader support.
+
+## When to enable CDC
+
+Consider CDC when all of the following apply:
+
+- You regularly write similar versions of the same dataset.
+- Your storage or transfer layer detects and reuses duplicate byte ranges.
+- Reducing storage or network transfer is more important than maximizing write
+  parallelism for an individual file.
+
+Leave CDC disabled for ordinary Parquet output unless you have measured a benefit
+in the system that stores or transfers the files. CDC is disabled by default.
+
+When CDC is enabled, DataFusion uses the sequential Arrow writer for each output
+file because the chunker's state must persist across row groups. This can reduce
+write throughput compared with DataFusion's parallel writer path. Writing
+different output files can still proceed concurrently.
+
+CDC operates independently for each output file. When `COPY` targets a
+directory, DataFusion distributes input RecordBatches in round-robin order across
+parallel output files; `datafusion.execution.minimum_parallel_output_files`
+defaults to four. If batching or file assignment changes between dataset
+versions, unchanged rows can move between files and reduce deduplication. For
+the best results, keep the input order and output file layout stable. Use a
+filename target for single-file output, or partition by stable keys when
+multiple files are required. See
+[Configuration Settings](configs.md#setting-configuration-options).
+
+## Enable CDC with SQL
+
+Set CDC for one [`COPY`](sql/dml.md#copy) operation with Parquet format options.
+The filename target in this example selects single-file output:
+
+```sql
+COPY (
+    SELECT
+        value AS id,
+        CONCAT('event-', CAST(value AS VARCHAR)) AS event
+    FROM generate_series(1, 100000)
+) TO 'cdc-output.parquet'
+STORED AS PARQUET
+OPTIONS (
+    'format.content_defined_chunking.enabled' 'true'
+);
+```
+
+The default chunking parameters are a good starting point. The next example
+specifies those defaults explicitly for one write; it does not change their
+values:
+
+```sql
+COPY source_table TO 'cdc-output.parquet'
+STORED AS PARQUET
+OPTIONS (
+    'format.content_defined_chunking.enabled' 'true',
+    'format.content_defined_chunking.min_chunk_size' '262144',
+    'format.content_defined_chunking.max_chunk_size' '1048576',
+    'format.content_defined_chunking.norm_level' '0'
+);
+```
+
+Change these values only after measuring with representative data.
+
+You can instead enable CDC for subsequent Parquet writes in the session:
+
+```sql
+SET datafusion.execution.parquet.content_defined_chunking.enabled = true;
+```
+
+The corresponding environment variable is
+`DATAFUSION_EXECUTION_PARQUET_CONTENT_DEFINED_CHUNKING_ENABLED`. See
+[Configuration Settings](configs.md#setting-configuration-options) for all ways
+to set session options.
+
+## Enable CDC with the Rust API
+
+Pass [`TableParquetOptions`] to [`DataFrame::write_parquet`]:
+
+```rust
+use datafusion::config::{ParquetCdcOptions, TableParquetOptions};
+use datafusion::dataframe::DataFrameWriteOptions;
+use datafusion::error::Result;
+use datafusion::prelude::SessionContext;
+
+#[tokio::main]
+async fn main() -> Result<()> {
+    let ctx = SessionContext::new();
+    let df = ctx
+        .sql("SELECT value AS id FROM generate_series(1, 100000)")
+        .await?;
+
+    let mut parquet_options = TableParquetOptions::default();
+    parquet_options.global.content_defined_chunking = ParquetCdcOptions::enabled();
+
+    df.write_parquet(
+        "cdc-output.parquet",
+        DataFrameWriteOptions::new().with_single_file_output(true),
+        Some(parquet_options),
+    )
+    .await?;
+
+    Ok(())
+}
+```
+
+Set the fields of `ParquetCdcOptions` directly to use non-default chunk sizes or
+normalization.

+| `norm_level`     | `0`     | Controls how aggressively boundaries are selected. Higher values can improve deduplication but create more small pages; recommended range is `-3` through `3`. |
+
+Chunk sizes are measured from logical column data before encoding and
+compression. Definition and repetition levels for nested data also count toward
+the size.
+
+Use the same CDC, encoding, compression, and schema settings when comparing
+dataset versions. Changing writer settings can change the page bytes and reduce
+deduplication even when the logical data is unchanged. Measure the deduplication
+ratio, output size, network transfer, and write time with representative data
+before changing the defaults.

Subject: [PATCH 844/878] fix: avoid buffering unbounded repartition output
 indefinitely (#24193)

## Which issue does this PR close?

- Closes #24044.

## Rationale for this change

`RepartitionExec` coalesces small batches on the producer side until the
configured batch size is reached or all input senders finish. An
unbounded input may never finish, so an available partial batch can be
withheld indefinitely. This prevents an incremental query from emitting
rows that are ready for downstream processing.

## What changes are included in this PR?

- Skip producer-side batch coalescing when the input is unbounded.
- Preserve the existing coalescing behavior for bounded inputs and
preserve-order execution.
- Add a regression test with an unbounded source that emits one partial
batch and then remains open.

## Are these changes tested?

Yes.

- `cargo fmt --all -- --check`
- `cargo test -p datafusion-physical-plan`
- `cargo clippy --all-targets --all-features -- -D warnings`
- The extended workspace test command required by `AGENTS.md`, including
all 503 sqllogictest files

The regression test fails on the previous implementation because the
partial batch is never emitted, and passes with this change. The
existing bounded-input coalescing test also continues to pass.

## Are there any user-facing changes?

Yes. Repartitioning an unbounded input can now emit partial batches
promptly instead of waiting indefinitely to fill the configured batch
size. This may expose smaller batches to downstream operators. There are
no public API changes.

<h2>1.8.6</h2>
<p>version 1.8.6</p>
<p>Changes since 1.8.5:</p>
<ul>
<li><code>update_mmap</code> and <code>update_mmap_rayon</code> (and by
extension <code>b3sum</code>) now
use <code>seek</code> rather than <code>metadata</code> to get the
length of a file/mapping,
and they tolerate <code>mmap</code> failures. That means
<code>b3sum</code> will now memory
map e.g. Linux block devices, which support mapping despite reporting
length 0 in <code>metadata</code>. Hashing <code>NUL</code> files on
Windows also works now,
where previously it was an error unless you used <code>--no-mmap</code>
or <code>&lt;</code>.

Subject: [PATCH 849/878] Add FixedSizeBinary support for MultiGroupBy (#23646)

- Closes #23645
- part of https://github.com/apache/datafusion/issues/22715

## Rationale for this change

Multi-Group-By has cases for regular Binary/LargeBinary types, but not
FixedSizeBinary

## Are these changes tested?

Yes.

## Are there any user-facing changes?

No

Subject: [PATCH 850/878] perf: remove per-row String allocations from the
 Spark url functions (#23884)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

N/A

## Rationale for this change

Three allocation problems in the `url` module, all on the per-row path.

**`url_encode`** built a `String` for every row:

```rust
fn encode(value: &str) -> Result<String> {
    Ok(byte_serialize(value.as_bytes()).collect::<String>())
}
```

**`url_decode`** ended with `.map(|parsed| parsed.into_owned())`. Both
`replace_plus` and `decode_utf8` return a `Cow` that *borrows* when
there is
nothing to rewrite, so `into_owned` allocated a `String` for every row
even when
the value contained no percent-escapes and no `+` at all.

**`parse_url`** built the all-null `key` array for the two-argument form
by
calling `append_null()` once per row against a builder with no capacity.

## What changes are included in this PR?

`url_encode.rs`:

- The three type branches build a pre-sized builder and share an
`encode_all!`
  loop that clears and refills one scratch `String` per batch.
- `UrlEncode::encode` is removed; it returned a `Result` whose error arm
was
  never constructed and now has no callers.

`url_decode.rs`:

- `decode` returns `Cow<'_, str>` instead of `String`. When
`replace_plus`
borrows, the decode borrows straight from the input; when it has already
allocated (the input contained `+`), owning the decoded form costs
nothing
  beyond what was already spent.
- The array paths append the `Cow` to a pre-sized builder rather than
  collecting `Result<StringArray>` from a per-row `String`.
- **API change:** `spark_handled_url_decode`'s second parameter changes
from
  `impl Fn(Result<Option<String>>) -> Result<Option<String>>` to a new
`OnDecodeError` enum. The `String` in that signature is what forced the
  allocation. Its only caller is `try_url_decode`, whose closure was
  `Err(_) => Ok(None)` — exactly `OnDecodeError::Null`.

`parse_url.rs`:

- The `append_null()`-per-row loop becomes
`new_null_array(&DataType::Utf8, len)`.

No behaviour change in any of the three.

## Are these changes tested?

Existing coverage pins the behaviour: `spark/url/url_encode.slt`,
`url_decode.slt`, `try_url_decode.slt`, and `parse_url.slt` assert
concrete
results including reserved characters, `+` handling, malformed
percent-encoding
(which must error for `url_decode` and yield NULL for `try_url_decode`),
and the
two- versus three-argument `parse_url` forms. All 5 `spark/url`
sqllogictest
files pass, along with the 258 `datafusion-spark` unit tests.

The `try_url_decode` unit test is what pins the `OnDecodeError::Null`
path,
since it drives a malformed input through the refactored signature.

Benchmarks are added separately in #23882 so the baselines can be
measured on
`main` before this lands.

### Benchmarks

Criterion, `apache/main` @ `f1ab86dad` as baseline. Median of the
reported
change interval.

`url_encode`:

| Benchmark | 1024 | 8192 |
| --- | --- | --- |
| `url_encode/utf8` | −57.1% | −48.2% |
| `url_encode/largeutf8` | −56.1% | −49.7% |
| `url_encode/utf8view` | −56.0% | −46.5% |

`url_decode`, split by whether the input actually needs unescaping:

| Benchmark | 1024 | 8192 |
| --- | --- | --- |
| `url_decode/plain_utf8` | −26.4% | −28.8% |
| `url_decode/plain_utf8view` | −29.0% | −27.2% |
| `url_decode/escaped_utf8` | −5.4% | −3.6% |
| `url_decode/escaped_largeutf8` | −4.7% | −3.2% |

The `plain` rows are the ones that benefit: with nothing to unescape the
decoded
value borrows its input. The `escaped` rows still have to allocate, so
they gain
only the pre-sized builder and the removed intermediate — a few percent,
as
expected.

`parse_url` has no benchmark; its change removes an `append_null()` loop
that
runs once per batch rather than affecting a measured per-row path.

## Are there any user-facing changes?

No change to SQL behaviour — all three functions return identical
results.

`spark_handled_url_decode` is public Rust API and its signature changes
as
described above; `OnDecodeError` is new public API on
`datafusion-spark`.

Subject: [PATCH 852/878] Expose accumulator state to allow prefix scanning
 (#24035)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

Expose state of aggregate streams within BWAG so downstream prefix
scanning can take place.

## API

```rust
// physical-plan/src/windows/bounded_window_agg_exec.rs
pub type FinalizedWindowStateObserver = Arc<
    dyn Fn(usize, &PartitionKey, &[Option<Vec<ScalarValue>>]) -> Result<()>
        + Send + Sync,
>;

impl BoundedWindowAggExec {
    pub fn with_finalized_state_observer(mut self, obs: FinalizedWindowStateObserver) -> Self { … }
}

// physical-expr/src/window/window_expr.rs
impl WindowState {
    /// `Accumulator::state()` if this is an aggregate window function, `None` otherwise.
    pub fn aggregate_state(&mut self) -> Result<Option<Vec<ScalarValue>>> { … }
}

Subject: [PATCH 853/878] perf: skip evaluating fully calculated window
 partitions (#24127)

## Which issue does this PR close?

- Related to #23982

## Rationale for this change

In Linear mode, BoundedWindowAggStream's evaluation sweep visits every
live partition for every window expression on every input batch. A
partition can be safely skipped if it received no new rows and already
row currently in the partition has its output fully computed. This
avoids a bunch of redundant work: re-evaluating the window function
arguments and ORDER BY columns against the retained batch, building an
empty result array, and other bookkeeping. This is particularly
expensive for workloads with many partitions where only a few of those
partitions receive rows in a given batch, as in the "32k sparse"
benchmark below.

Benchmarks:

- linear / range / single / 100 dense:      42.3 ms ->  42.0 ms (~noise)
- linear / range / single / 10000 dense:   158.7 ms -> 152.5 ms (-3.9%)
- linear / range / single / 32768 sparse:  161.1 ms -> 108.0 ms (-33.0%)
- linear / rows  / single / 10000 dense:   132.0 ms -> 127.5 ms (-3.4%)
- linear / range / multi  / 10000 dense:   255.9 ms -> 236.4 ms (-7.6%)
- sorted / range / single / 10000:          33.1 ms ->  33.7 ms (~noise)

## What changes are included in this PR?

* Skip evaluating window expressions for fully calculated partitions
* Add test case
* Add assert checking that per-window-agg and per-partition state is
consistent

## Are these changes tested?

Yes. Existing tests pass. Added a new test to verify that "evaluate
partition -> skip partition -> evaluate partition" sequence results in
resuming accumulator states appropriately. I also checked that if the
`is_end` conjunct is removed from the skip condition, the new assert
added above fires and catches the bug.

## Are there any user-facing changes?

No.

Subject: [PATCH 854/878] fix(lambda): only push referenced params into the
 merged batch (#24162)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

basically this PR https://github.com/apache/datafusion/pull/22853 + a
few more tests

## Rationale for this change

The current lambdas in DF only take a single parameter `(v -> ...)`, so
nobody had noticed that `LambdaExpr` mishandles lambdas with more than
one parameter. The bug surfaced while working on `transform_values`
(#22689), which needs `(k, v) -> expr ` two parameters, one of which is
very often unused (e.g. `(k, v) -> v * 2`, k never referenced).

The bug is that when a higher order function with more than 1 param
evaluates a lambda, it fills each parameter into a slot based on its
declared position — for example for `(k, v) -> v` `k` always goes into
slot 0, `v` always into slot 1. `LambdaExpr` separately scans the body
and renumbers whatever it finds referenced into a dense `0..n` range, to
avoid carrying around columns nothing uses (like `v` in this case). That
renumbering is fine for outer captures, but applying it to the lambda's
own parameters is wrong, because it changes where the body looks for a
value without changing where the evaluator put it.

### Example:

in `(k, v) -> v` `v` is declared second (slot 1), but since it's the
only parameter the body references, the renumbering logic reassigns it
to slot 0. The evaluator, unaware of this, writes `k`'s values into slot
0 and `v`'s into slot 1. So the body ends up reading slot 0 expecting
`v` — and gets `k` instead. So the results end up being incorrect.

## What changes are included in this PR?

- `LambdaExpr` now computes `used_params`: which is the subset of its
own declared parameters that are actually referenced in the body.
- `LambdaArgument::new` takes `used_params` and only pushes the
referenced parameters in the body into the merged batch, in original
declaration order — so the body's indices always line up with what's
actually built.
- `HigherOrderFunctionExpr::evaluate` forwards `lambda.used_params()` to
`LambdaArgument::new`

## Are these changes tested?

yes, added two new tests one for the unused-parameter case and
nested-lambda for the shadowing case.

## Are there any user-facing changes?

The only public api change is on `LambdaArgument::new ` which now
requires a new argument: `used_params: &HashSet<String>`, however
LambdaArgument::new is very unlikely to be called outside datafusion,

Subject: [PATCH 855/878] Enable dynamic filters for range-partitioned joins
 (#23854)

## Which issue does this PR close?

- Closes https://github.com/apache/datafusion/issues/23376.

## Rationale for this change

Partitioned hash joins build one dynamic filter per build partition.
Existing routing uses `hash(key) % N`, which cannot reproduce a Range
partitioning layout.
Compatible Range co-partitioned joins instead need to route probe rows
using their existing ordering and split points.

## What changes are included in this PR?

- Enable dynamic filter pushdown for hash joins with compatible
Range-partitioned inputs.
- Build a searched `CASE` expression that routes probe rows to the
corresponding partition filter using the Range ordering and split
points.
- Move the TopK lexicographic filter builder into the shared ordering
module for reuse.

## Are these changes tested?

unit test.

## Are there any user-facing changes?

Yes. This PR adds `RangeExpr` to the physical-expression protobuf model,
which adds the public `ExprType::RangeExpr` enum variant. Downstream
Rust consumers that exhaustively match `ExprType` must handle the new
variant.

It also enables dynamic-filter pushdown for compatible Range-partitioned
joins.

Subject: [PATCH 856/878] Docs: Add PR review guide (#24051)

## Which issue does this PR close?

- https://github.com/apache/datafusion/issues/23839
- related to the disucssions tarted by @jayzhan211 in
https://github.com/apache/datafusion/issues/21038

## Rationale for this change

As our project grows both in terms of number of users as well as the
number of PRs submitted (due to agents and increasing usage) I would
like to trying to document / automate as much as possible

As one of the largest bottlenecks at the moment is PR review, so making
that more efficient I think will help us improve the flow of code in the
project and make best use of our committers' time. My rationale is that
by documenting this process more clearly
1. PR submitters (and/or their agents) can pre-review their own PRs to
reduce back and forth with committers
2. Committers (and/or their agents) have a checklist they can apply when
reviewing

I also strongly believe effective documentation should be written for
**both** humans and agents so I purposely didn't make a specific skill
for this (instead I made a skill that points at the relevant parts of
the docs)

## What changes are included in this PR?

1. Add a new PR review page to the contributor guide
4. Try and distill project best practice
5. Leave links to help people/agents find it

## Are these changes tested?

By CI

## Are there any user-facing changes?

New doc page

+# DataFusion PR Review
+
+This skill describes the mechanics for doing PR reviews from the command line.
+
+When creating a PR, skip the "Collect PR context" step and instead check the
+changes against each area of the
+[PR review guide](../../../docs/source/contributor-guide/pr_review.md) before
+submitting.
+
+## Collect PR context
+
+- Check out the PR locally: `gh pr checkout <PR number>` (ask first if the
+  working tree has other work in progress).
+- Fetch the PR description, comments, and reviews:
+  `gh pr view <PR number> --json title,body,comments,reviews`
+- Fetch CI status: `gh pr checks <PR number>`.
+
+## Compute the diff
+
+```bash
+# find the remote that points at apache/datafusion (e.g. `apache`, `upstream`, or `origin`)
+UPSTREAM=$(git remote -v | grep -m1 'apache/datafusion' | cut -f1)
+git fetch $UPSTREAM main
+git diff $(git merge-base HEAD $UPSTREAM/main)
+```
+
+## Review checklist

+# Reviewing Pull Requests
+
+When reviewing PRs, our primary goal is to improve DataFusion and its community
+together. PR feedback should be constructive and help improve the code as well
+as the understanding of the contributor.
+
+Review bandwidth is currently our most limited resource, and reviews from the
+broader community are both welcomed and encouraged. Reviewing PRs is a great way
+to learn the codebase, and you do not need to be a committer to leave valuable
+review feedback. In fact, one of the best ways to become a committer is to
+thoughtfully review other PRs.
+
+Please ensure any comments you leave contain a rationale and suggested
+alternative -- it is frustrating to be told "don't do it this way" without any
+clear reason or alternative provided.
+
+The criteria in this guide are also a useful checklist when preparing your own
+PR for review.

+The overall PR lifecycle (CI triggering, approval, the 24-hour rule for
+"major" PRs, and merging) is described in the
+[Pull Request Overview](index.md#pull-request-overview) section of the
+contributor guide.
+
+Practical tips:
+
+1. Check out the changes locally to explore them in your IDE or with an
+   agent, e.g. `gh pr checkout <PR number>` using the [GitHub CLI].
+2. There is normally no need to rerun locally any tests that CI has already run.
+3. Leave comments on specific lines of the diff where possible, so the
+   discussion has context.
+4. If you review a PR but don't feel confident approving it, leaving comments
+   is still valuable: a partial review (e.g. "I reviewed the tests and they
+   look good") helps the next reviewer focus their time.
+5. Anything that does not need to block the current PR can be noted as a
+   potential follow-up (ideally by filing an issue), keeping the PR focused
+   and quick to merge.
+

+
+## Review the PR Description
+
+The PR description is often what users and contributors will find when they have
+a question about the intention behind a change, or when the code itself is not
+clear. The PR description also becomes the extended commit message.
+
+Check that the description:
+
+1. Concisely describes the **problem being solved from the user's point of
+   view**.
+
+2. Follows the [PR template], and answers the template's questions.
+
+3. Accurately describes the content of the PR, including any relevant context or
+   background.
+   Great descriptions have a high signal-to-noise ratio, summarizing
+   important implementation changes without repeating technical minutiae that
+   are already present in the code itself.
+
+4. Explicitly calls out any user-facing or API changes (see
+   [Review the Code](#review-the-code) below).
+
+[pr template]: https://github.com/apache/datafusion/blob/main/.github/pull_request_template.md
+
+## Review the Code Comments
+
+The goal of code comments is to help future readers of the code understand what
+is not obvious from reading the code itself. Great comments make the code easier
+to reason about for readers with the expected background, and help future
+maintainers.
+
+Some practical guidelines for reviewing comments:
+
+1. The code has adequate comments focused on the **rationale** for any
+   non-obvious change (the "why"), not a restatement of what the code does
+   (the "what"), which is typically clear from reading the code itself.
+2. Comments do not narrate irrelevant internal implementation details or the
+   history of how the change was developed (this is common in LLM-assisted
+   code, e.g. "// changed to use a HashMap" or "// this handles the case
+   mentioned above"). Such comments become irrelevant as soon as the PR merges.
+3. When comments refer to other structs, functions, or modules, they should use
+   [rustdoc intra-doc links] (e.g. `` [`SessionContext`] ``) rather than plain
+   text names, so that `cargo doc` link checking ensures the references stay
+   valid as the code evolves.
+4. New public APIs have doc comments, including examples where appropriate
+   (doc examples are also tested by CI, so they double as test coverage).
+5. When documenting modules, functions, or fields, start with simple examples
+   and intuitive explanations, and optionally add formal, math-like
+   definitions when necessary. This makes the implementation easier to reason
+   about.
+6. When something is confusing on first read, treat that as a good
+   opportunity to improve the comments.
+
+[rustdoc intra-doc links]: https://doc.rust-lang.org/rustdoc/write-documentation/linking-to-items-by-name.html
+
+## Review the Test Coverage
+
+Check that the feature or fix is covered sufficiently with tests (see the
+[Testing](testing.md) guide for more details): the PR should include tests for
+any new functionality, and a bug fix should include a test that reproduces the
+reported problem.
+
+Guidelines for evaluating tests:
+
+1. Prefer `sqllogictest` (`.slt`) tests or DataFrame API tests where
+   possible, as they exercise **user-visible behavior** and are less coupled
+   to internal implementation details than unit tests.
+2. Verify tests cover edge cases and common failure scenarios, not just the
+   common successful path. However, it is NOT necessary to test every possible
+   error path, especially if it is difficult to trigger or unlikely to occur in
+   practice.
+3. Verify test coverage of changed code using the `codecov` check on the PR,
+   or by running [`cargo llvm-cov`] locally for an HTML report. Use judgment
+   about any uncovered lines -- the goal is confidence in the change, not
+   slavishly hitting some coverage number.
+4. Avoid tests with lots of repeated boilerplate: when many tests share
+   near-identical setup, it is hard to understand what is different
+   (and thus what is actually being tested) between them. Make the _difference_
+   between cases obvious.
+5. Check that tests assert on specific expected values or plans (e.g. via
+   `insta` snapshots or `.slt` expected output) rather than merely checking
+   "no error occurred".
+6. Verify tests actually cover the bug ("Ablation Testing"): For bug fixes, revert
+   the fix locally and check that the new test fails without it (i.e. the test
+   actually reproduces the bug or covers the new feature).
+
+[`cargo llvm-cov`]: https://github.com/taiki-e/cargo-llvm-cov
+
+## Review the Code
+
+Check that:
+
+1. The code is clear and fits the style of the existing codebase.
+2. New functions and tests are placed near similar functions and
+   tests. For example, helper functions should be defined close to where they are used,
+   and new tests should be placed in the same module as the code they test.
+   SLT tests should be placed in an existing .slt file with related functionality,
+   unless the new tests are large enough to justify their own file.
+3. New APIs are consistent with existing public APIs and patterns; where a
+   similar mechanism already exists, the PR should extend it rather than
+   introduce a parallel one.
+4. Any changes to the public API follow the [API health policy].
+5. The change is appropriately scoped: unrelated refactoring, formatting
+   churn, or drive-by changes make review longer and are better as separate
+   PRs.
+6. New errors are actionable, mention the offending item, and use
+   the right error variant (e.g. `plan_err!` for user-triggerable errors vs
+   `internal_err!` for invariant violations).
+
+[api health policy]: api-health.md
+
+## Review the Performance
+
+Performance is a key feature of DataFusion. See [Performance Improvements](index.md#performance-improvements)
+for the project policy: an improvement should be "enough" to justify any
+added code complexity, and performance PRs should come with benchmark
+results.
+
+When reviewing:
+
+1. Find any relevant existing benchmarks and run them against `main`:
+   the [system-level SQL benchmarks] are run with `bench.sh` (see the
+   [benchmarks README]), and microbenchmarks (e.g. in
+   `datafusion/functions/benches`) are run with `cargo bench`.
+2. Be aware that benchmarking on a machine where other
+   work is being done will make results hard to reproduce. Prefer a quiet,
+   dedicated machine and repeated runs.
+3. If the PR claims a performance improvement, check that the reported
+   results are reproducible and that the benchmark exercises the changed
+   code path.

+
+## Best Practices for Reviewers
+
+Here are some suggested best practices to follow when reviewing PRs.
+
+### Review Tone: Thank Contributors and Praise Good Work Specifically
+
+Open reviews by thanking the author by name, and when a PR is well done, say
+specifically what makes it good -- positive feedback encourages people to keep
+contributing and helps them understand what is valued in the project.
+
+### State Approval Conditions Explicitly
+
+If you are not ready to approve, list concretely what you would need to see
+before approving (e.g. "benchmark results and an upgrade guide entry") so
+the author has a clear path to merge.
+
+### Defer Non-Blocking Work to Follow-On Issues
+
+Explicitly defer non-critical suggestions to a follow-on PR and file
+(or ask the author to file) issues for them, so good PRs merge quickly
+without scope creep.
+
+Similarly, when a PR mixes refactoring with behavior changes or fixes a narrow
+problem with a broad mechanism, ask for it to be split or scoped down rather
+than reviewing it as-is.
+
+### Narrate What You Verified When Approving
+
+Rather than a bare "LGTM", say what you actually checked ("traced the state
+transitions by hand", "confirmed the hasher change cannot affect ordering")
+so it is clear what was verified and what was not.
+
+### Invite Additional Committers on Core Changes
+
+For changes to core, widely shared code, leave the PR open for other
+committers to look at and cc those who know the area, even after you have
+approved.

Subject: [PATCH 857/878] chore(proto): remove never-released deprecated
 PhysicalPlanNodeExt scaffolding (#24269)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Part of #23494. This closes out that EPIC's "Remove the
`#[deprecated(since = "55.0.0")]` `PhysicalPlanNodeExt` scaffolding"
cleanup item.

## Rationale for this change

`PhysicalPlanNodeExt` currently carries 59 `#[deprecated(since =
"55.0.0")]` methods — per-operator `try_into_*_physical_plan` /
`try_from_*_exec` shims left behind by the `ExecutionPlan::try_to_proto`
/ `try_from_proto` migration. Each is a thin forwarder to the operator's
own hook; none is called by DataFusion.

**These methods have never shipped in any DataFusion release**, so no
deprecation window is owed:

- At the `54.1.0` tag they were **private inherent** methods on `impl
protobuf::PhysicalPlanNode` — not `pub`, not on a public trait:

  ```console
$ git show 54.1.0:datafusion/proto/src/physical_plan/mod.rs | sed -n
'700,701p'
  impl protobuf::PhysicalPlanNode {
      fn try_into_explain_physical_plan(
  ```

- #21929 (merge commit `077f08a9a6632324c95275dd15b5dd5b1f14006f`,
merged 2026-05-22) is what promoted them into the public
`PhysicalPlanNodeExt` trait, and it is **not** an ancestor of `54.1.0`
(54.1.0 was cut off the 54.0.x line):

  ```console
$ git merge-base --is-ancestor 077f08a9a6632324c95275dd15b5dd5b1f14006f
54.1.0; echo $?
  1
  ```

- Every one of them is marked `#[deprecated(since = "55.0.0")]`, so
55.0.0 would be the very first release to expose them — already
deprecated.

The [API health
policy](https://github.com/apache/datafusion/blob/main/docs/source/contributor-guide/api-health.md)
exists to protect API that users could have depended on *from a
release*. Nothing released ever exposed these. Deleting them before the
55.0.0 branch is cut avoids shipping 59 dead-on-arrival public methods
that we would then be obliged to carry for a full deprecation cycle.

Removing them also deletes ~1350 lines from
`datafusion/proto/src/physical_plan/mod.rs`, which makes the remaining,
load-bearing surface of the trait much easier to read.

## What changes are included in this PR?

- Delete the 59 `#[deprecated(since = "55.0.0")]` methods from
`PhysicalPlanNodeExt` (29 `try_from_*_exec` encoders, 30 `try_into_*`
decoders).
- Drop three `use` statements that became unused as a result:
`DataSinkExec`, `BoundedWindowAggExec`, `SortMergeJoinExecNode`.
- Delete `deprecated_projection_shim_decodes_argument_not_self`, the one
test that existed solely to pin the behaviour of the
`try_into_projection_physical_plan` shim.

Deliberately **not** changed:

- The trait itself and its 16 non-deprecated methods stay: `node()`,
`try_into_physical_plan_with_converter`,
`try_into_physical_plan_with_context`,
`try_from_physical_plan_with_converter`, the
scan/extension/generate-series decoders and `try_from_data_source_exec`
/ `try_from_lazy_memory_exec` that the central dispatch still calls.
- `AsExecutionPlan`, `PhysicalExtensionCodec`,
`PhysicalProtoConverterExtension` are untouched.
- **No `.proto` files and no encode/decode dispatch behaviour are
touched — the wire format is unchanged.**
- The `TryFromProto<&protobuf::{Json,Csv,Parquet}Sink>` impls in
`from_proto.rs` mentioned in #23494 are **not** removed here: they are
not marked `#[deprecated]` (there are no `deprecated` attributes
anywhere in `from_proto.rs` / `to_proto.rs`), so they don't fall under
the "never-released deprecated scaffolding" argument above and deserve
their own decision.

## Are these changes tested?

Covered by the existing test suite; the change is a pure deletion of
unreferenced code.

The one deleted test only exercised the deprecated shim. The underlying
`ProjectionExec::try_to_proto` / `ProjectionExec::try_from_proto` hook
keeps full roundtrip coverage through the existing `roundtrip_test`
cases in `datafusion/proto/tests/cases/roundtrip_physical_plan.rs` (e.g.
`roundtrip_like`, `roundtrip_projection_source`,
`roundtrip_empty_projection`).

Verified locally:

- `cargo fmt --all`
- `./ci/scripts/rust_clippy.sh` (CI's exact workspace + `--all-targets`
clippy, clean)
- `RUST_BACKTRACE=1 cargo test --profile ci -p datafusion-proto
--features avro,json` — 238 tests pass, 0 failures
- `cargo check -p datafusion-examples --examples` (two examples import
`PhysicalPlanNodeExt`; both only use methods that stay)
- `cargo doc -p datafusion-proto --no-deps` (no dangling intra-doc
links)

## Are there any user-facing changes?

Removal of 59 public trait methods, all of which were already
`#[deprecated]` and none of which ever appeared in a published release.
No Upgrade Guide entry is needed, because there is no released version
anyone could be upgrading *from* that had this API.

Subject: [PATCH 858/878] Restore the From / TryFrom proto conversions dropped
 since 54.1.0 (#24205)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #24019.
- closes https://github.com/apache/datafusion/issues/23494

## Rationale for this change

`datafusion-proto` 54.1.0 publishes 39 `From` / `TryFrom` impls
converting between DataFusion types and their protobuf messages. On
`main` all of them were replaced by the crate-local `FromProto` /
`TryFromProto` traits introduced in #21929, so code written against the
released version stops compiling:

```rust
let proto = protobuf::PartitionedFile::try_from(&file)?;   // no longer resolves on main
let frame = WindowFrame::try_from(proto_frame)?;           // no longer resolves on main
```

That was collateral damage from the orphan-rule workaround, which was
needed during the migration but can now be unwound to result in no
breaking change across releases.

## What changes are included in this PR?

Each conversion moves to a crate that owns one side of it, and goes back
to being a plain `From` / `TryFrom` — the shape 54.1.0 published. Error
types are unchanged (`FromProtoError` decoding, `ToProtoError` encoding,
`DataFusionError` for the datasource types).

| Types | New home |
|---|---|
| `PartitionedFile`, `FileRange`, `FileGroup`, `JsonSink`, `CsvSink`,
`ParquetSink`, `FileSinkConfig` | already moved by #24006 / #23781 —
this PR just deletes the `TryFromProto` shims that delegated to them |
| `WindowFrame`, `WindowFrameBound`, `WindowFrameUnits`,
`MergeIntoClauseKind`, `NullTreatment` | `datafusion-expr`, behind a new
`proto` feature (optional `datafusion-proto-common` /
`datafusion-proto-models` deps, mirroring `datafusion-datasource`) |
| `UnnestOptions`, `TableReference`, `StringifiedPlan`, `JoinType`,
`JoinConstraint`, `NullEquality`, `CsvOptions`, `JsonOptions`, and the
parquet options types | `datafusion-proto-models`, on the local proto
type — their DataFusion side sits *below* that crate in the graph, the
same arrangement `datafusion-proto-common` already uses for
`ScalarValue` / `Statistics` |
| `CsvFormatFactory`, `JsonFormatFactory`, `ParquetFormatFactory` |
`datafusion-datasource-{csv,json,parquet}`, behind each crate's existing
`proto` feature |
| `Column` <-> `protobuf::PhysicalColumn` | `datafusion-physical-expr`;
`Column::try_to_proto` / `try_from_proto` now go through it instead of
building the message inline |

`TryFrom<&[PartitionedFile]> for protobuf::FileGroup` needed one extra
step. `datafusion-datasource` cannot host it — `&T` is `#[fundamental]`
but `[T]` is not, so `&[PartitionedFile]` counts as foreign there
(`error[E0117]: slices are always foreign`). But in
`datafusion-proto-models` the *self* type is local, which is all the
orphan rule needs, and staying generic over the element avoids naming
`PartitionedFile`, which sits above that crate in the graph:

```rust
impl<T> TryFrom<&[T]> for protobuf::FileGroup
where
    for<'a> &'a T: TryInto<protobuf::PartitionedFile, Error = DataFusionError>,
{ ... }
```

The bound is satisfied by `TryFrom<&PartitionedFile> for
protobuf::PartitionedFile` in `datafusion-datasource`, so
`protobuf::FileGroup::try_from(&files[..])` resolves for callers exactly
as it did in 54.1.0.

Two items beyond the issue's checklist, both needed to reach zero
implementors:

- the parquet options conversions (`ParquetOptions`,
`TableParquetOptions`, `ParquetColumnOptions`, `ParquetCdcOptions`) —
the issue's table undercounts `file_formats.rs` because they live in a
private module, but trait impls are global, so they were public API too.
They return as `TryFrom`; `main` had already made them fallible, so an
exact restore of 54.1.0's infallible `From` isn't available.
- `From<&protobuf::PhysicalColumn> for Column`, which the issue's
evidence table counts but no work item names.

Not restored, and worth calling out: `From<protobuf::dml_node::Type> for
WriteOp` and its reverse. `main` replaced them with `parse_write_op` /
`serialize_write_op` because `MergeInto` carries a payload a `From` impl
cannot express. That is a separate, deliberate change.

Finally, `convert.rs` and `convert_required_proto!` are deleted. #21929
introduced `FromProto` / `TryFromProto` so the `datafusion-proto-models`
extraction could land without relocating ~39 conversions at the same
time, and flagged them there as "a known workaround, not the end state",
with dropping them listed under Future work. With every conversion moved
they have no implementors and no callers. Neither trait has ever shipped
in a release, so they are removed outright rather than deprecated —
there is nothing for downstream users to migrate off, and doing it now
keeps the workaround out of the released API entirely.

## Are these changes tested?

Yes.

- New `datafusion/proto/tests/cases/public_conversions.rs` coerces all
45 proto conversions in the touched crates to `fn` pointers (the 39 from
54.1.0 plus the ones added on `main`). This is the regression guard the
issue asks for: it fails to compile when an impl is removed, and stays
quiet when one merely moves between crates, which is exactly the case
`cargo-semver-checks` cannot see.
- New round-trip tests next to the moved impls in `datafusion-expr` and
`datafusion-proto-models` (window frames, table references, join enums,
unnest options, stringified plans).
- The `PartitionedFile` tests move from `datafusion-proto` to
`datafusion-datasource`, alongside the logic they cover; two that
duplicated existing coverage there are dropped.
- Existing round-trip suites (`roundtrip_logical_plan`,
`roundtrip_physical_plan`) pass unchanged, which is the real wire-format
check.
- Every moved impl body was diffed against `main`: 22 are byte-identical
modulo the trait rename, and the other 9 differ only by `Self::`
shorthand, error-type aliasing, and rustfmt reflow. No serialization
logic changed.
- `./dev/rust_lint.sh`, `cargo machete`, and the extended test suite all
pass at HEAD. Also checked: `datafusion-proto` without `parquet`,
`datafusion-expr` with `proto` off and `--no-default-features`, the
format crates without `proto`, and `json` on both proto crates.

## Are there any user-facing changes?

Yes, and they restore rather than break the released API.

- The 39 conversions removed since 54.1.0 compile again. Trait impls are
global, so `X::try_from(&proto)` / `proto.try_into()` resolve regardless
of which crate now hosts the impl — no import changes needed, and no
upgrade-guide entry for the moves.
- One genuine delta remains: the parquet options conversions are
`TryFrom` rather than 54.1.0's infallible `From`. That predates this PR
— `main` had already made them fallible — but it is a real 54.1.0 ->
55.0.0 break and was undocumented, so it is now in the 55.0.0 upgrade
guide with a migration snippet.
- `FromProto` / `TryFromProto` and `convert_required_proto!` are gone.
Not a breaking change: they exist only on `main` and appear nowhere in
54.0.0 or 54.1.0.
- `datafusion-expr` gains an off-by-default `proto` feature. Additive.
- `datafusion-proto-models` gains a direct `datafusion-common`
dependency (already present transitively) and two new public modules.

Keeping the `api change` label for the parquet options fallibility.

-//! standard library's `From` / `TryFrom`, so callers spell the conversion

-//! `(&p).into()` / `(&p).try_into()?`.

+### `datafusion-proto`: parquet options conversions are fallible
+
+`protobuf::ParquetOptions` and `protobuf::TableParquetOptions` validate
+`writer_version` when converting into their `datafusion-common` counterparts, so
+those conversions are `TryFrom` rather than `From`.
+
+Every other `From` / `TryFrom` conversion between DataFusion types and
+`datafusion_proto::protobuf` messages is unchanged. Several impls moved to the
+crate that owns their DataFusion type, but trait impls are global, so
+`X::try_from(&proto)` and `proto.try_into()` still resolve with no import
+changes.
+
+**Migration guide:**
+
+```rust,ignore
+// Before
+let opts = ParquetOptions::from(&proto_opts);
+let table_opts = TableParquetOptions::from(&proto_table_opts);
+
+// After
+let opts = ParquetOptions::try_from(&proto_opts)?;
+let table_opts = TableParquetOptions::try_from(&proto_table_opts)?;
+```

Subject: [PATCH 859/878] refactor: make apply_expression_roots more ergonomic
 (#24226)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Follow up to
https://github.com/apache/datafusion/pull/24018#pullrequestreview-4886401724

## Rationale for this change

Allows us to rewrite
```rust
datafusion_physical_plan::apply_expression_roots(
    self.projection
        .source
        .iter()
        .map(|proj_expr| &proj_expr.expr),
    f,
)
```
as simply
```
datafusion_physical_plan::apply_expression_roots(self.projection.source.iter(), f)
```

## What changes are included in this PR?

Adds a new trait and implements it for `ProjectionExpr` which
facilitates the syntax above ^

```
pub trait PhysicalExprRoot {
    /// Returns the physical expression at this root.
    fn as_physical_expr_root(&self) -> &Arc<dyn PhysicalExpr>;
}
```

## Are these changes tested?

Should be covered by existing coverage.

Subject: [PATCH 861/878] refactor: moving WindowTopN before EnsureRequirements
 (#24191)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Which issue does this PR close?

- Closes #21594

## Rationale for this change

The WindowTopN physical optimizer rule currently runs after
EnsureRequirements, which means it must pattern-match through SortExec
nodes that EnsureRequirements inserts:

```
FilterExec(rn <= K)
  [optional ProjectionExec]
    BoundedWindowAggExec(ROW_NUMBER PARTITION BY ... ORDER BY ...)
      SortExec(partition_keys, order_keys)   ← inserted by EnforceSorting
```

By moving WindowTopN to run before EnsureRequirements, we can simplify
the logic to avoid pattern-matching through `SortExec` node and instead
use the `ORDER BY` and `PARTITION BY` on the `BoundedWindowAggExec`

## What changes are included in this PR?

Moved `WindowTopN` to run before `EnsureRequirements`, and updated its
logic to not expect a `SortExec` and instead use the `ORDER BY` and
`PARTITION BY` on the `BoundedWindowAggExec`

## Are these changes tested?

Yes

## Are there any user-facing changes?

These are just optimizer changes (order of optimizations and internal
logic of `WindowTopN`), no API changes

Subject: [PATCH 862/878] fix: infer placeholder types in GROUP BY, HAVING,
 QUALIFY and ORDER BY (fix for #24042) (#24043)

The SELECT list is planned by sql_to_expr, which infers placeholder
types. These four clauses are planned by sql_expr_to_logical_expr, which
does not, so the same expression written in both places does not compare
equal.

The result is that a grouping key containing a placeholder is never
matched against the identical SELECT expression, and the columns inside
it are reported as ungrouped. The same query with literals in place of
the placeholder plans fine. QUALIFY fails differently, on a duplicate
field name, because the typed and untyped spellings print alike but are
not equal.

Adds a planner test per clause.

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Closes #24042.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.
-->

I think it's clearly explained above / in issue.

## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

New tests for each clause case + inferring types in the clauses.

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes tests are there.

## Are there any user-facing changes?

No.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 863/878] perf: prune window state only for partitions that
 made progress (#24148)

## Which issue does this PR close?

- Related to #23982

## Rationale for this change

After ingesting a batch of data, updating accumulator state, and
emitting new output rows, `BoundedWindowAggStream` prunes each partition
to reclaim state that is no longer needed: `prune_out_columns` trims
emitted results that are no longer needed, and `prune_partition_batches`
drops buffered input rows that aren't needed by any window expression.

Both functions did work proportional to the # of live partitions,
despite pruning being a no-op for partitions that didn't receive rows in
the most recent batch:

- `prune_out_columns` looked up every partition's buffer by hashing its
partition key and re-sliced every result column, including zero-length
prunes that rebuilt an identical column.
- `prune_partition_batches` put an entry in its prune-count map for
every live partition, cloning each partition's key (a Vec<ScalarValue>);
for sparse workloads (# of partitions > batch-size), most prune counts
will be zero and this did a lot of redundant work.

Restructure both passes to pass over quiet partitions:

- `prune_out_columns` iterates the partition buffers and only processes
partitions with a nonzero emitted-row count. Hash lookups now happen
only for partitions that emitted rows since the previous pass.
- `prune_partition_batches` only keeps partitions with positive prune
counts in its map

Benchmarks (after applying #24127):

- linear / range / single / 100 dense:      43.2 ms ->  43.0 ms (~noise)
- linear / range / single / 10000 dense:   156.4 ms -> 157.0 ms (~noise)
- linear / range / single / 32768 sparse:  111.2 ms ->  86.3 ms (-22.4%)
- linear / rows  / single / 10000 dense:   133.2 ms -> 133.3 ms (~noise)
- linear / range / multi  / 10000 dense:   246.3 ms -> 245.9 ms (~noise)
- sorted / range / single / 10000:          34.5 ms ->  34.3 ms (~noise)

## What changes are included in this PR?

* Optimize window state pruning as described above
* Update and clarify comments in several places

## Are these changes tested?

Yes, covered by existing tests.

## Are there any user-facing changes?

No.

Subject: [PATCH 864/878] FFI: plumb with_updated_config for FFI_ScalarUDF
 (#22797)

## Which issue does this PR close?

Part of #22330.

## Rationale for this change

`ForeignScalarUDF` inherits the default `with_updated_config`, so
producer overrides are lost across the FFI boundary.

## What changes are included in this PR?

- Forward `with_updated_config` through `FFI_ScalarUDF`.
- Reuse the existing placement and timezone UDFs for unit and
dynamic-library coverage.
- Log transport failures before the infallible trait method returns
`None`.
- Update the FFI skill to cover error handling, owned returns, and
fixture reuse.

## Are these changes tested?

- `cargo test -p datafusion-ffi --features integration-tests`
- `cargo clippy --all-targets --all-features -- -D warnings`
- `./ci/scripts/doc_prettier_check.sh --write --allow-dirty`

## Are there any user-facing changes?

The FFI ABI changes. Foreign libraries must rebuild against the new
DataFusion version.

Call `datafusion_ffi::tests::utils::get_module()` to load the cdylib, invoke your constructor through the returned `ForeignLibraryModule`, convert into `Arc<dyn X>`, and exercise every method.
 
+When adding a method to an existing wrapper, reuse an existing fixture and constructor when a small trait-method override can cover it. This applies both to omitted default methods and methods newly added to the trait. Add a dedicated test type or `ForeignLibraryModule` field only when the existing fixtures cannot cover the method.

 What integration tests catch that unit tests cannot:
 
 - **Real ABI layout bugs.** Two builds means the consumer's view of `FFI_X` is reconstructed from declaration, not aliased to the producer's memory. Mismatched alignment, padding, niche optimization, or accidentally non-`#[repr(C)]` types surface here.

 - **Logical `Expr` / `LogicalPlan`**: serialize via `datafusion-proto` using the embedded `FFI_LogicalExtensionCodec`. Same for physical plans → `FFI_PhysicalExtensionCodec`.
 - **Enums** (`Volatility`, `TableType`, `InsertOp`, `TableProviderFilterPushDown`): `#[repr(u8)]`, with `From<Native> for FFI_X` and `From<&FFI_X> for Native`. Always write a round-trip unit test that exercises every variant.
 - **Errors**: every `FFI_X` method that can fail returns `FFI_Result<T>`. Use the `sresult!`, `sresult_return!`, `df_result!` macros from `src/util.rs` — do not roll your own.
+- **Infallible trait methods**: if an FFI call can fail but the native trait cannot return the error, log the transport error before returning the trait's fallback (`None`, `false`, or a default). Never discard it with `.ok()`, `.unwrap_or_default()`, or equivalent.
+- **Owned FFI returns**: consume an owned `FFI_X` with `From<FFI_X>` instead of converting through `&FFI_X` and cloning across the boundary. Keep the borrowed conversion's local marker fast path.

packs.</p>
<h2>[UNRELEASED]</h2>
<p>No user facing changes.</p>
<h2>4.37.6 - 04 Aug 2026</h2>
<ul>
<li>Changed the default filepath for the new remote file address format
that was introduced in CodeQL Action 4.37.0 / 3.37.0 to
<code>.github/codeql-config.yml</code> to align it with the suggested
path that is used elsewhere. <a
href="https://redirect.github.com/github/codeql-action/pull/4070">#4070</a></li>
</ul>
<h2>4.37.5 - 03 Aug 2026</h2>
<ul>
<li>Fixed a bug where a network error while streaming the download of
the CodeQL bundle could terminate the <code>init</code> Action instead
of falling back to downloading the bundle before extracting it. <a
href="https://redirect.github.com/github/codeql-action/pull/4061">#4061</a></li>
</ul>
<h2>4.37.4 - 29 Jul 2026</h2>
<ul>
<li>This version of the CodeQL Action adds support for the
<code>tools</code> input for the <code>codeql-action/init</code> step to
be specified using a <code>github-codeql-tools</code> <a
href="https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization">repository
property</a>. This feature will gradually be rolled out following the
release of this version. Once rolled out, this allows for the CodeQL CLI
version that is used in GitHub-managed workflows, such as Default Setup,
to be set to a custom value. For example, customers who run into issues
with rate limits when a new CodeQL CLI version is released can set the
value to <code>toolcache</code> to always use the CodeQL CLI version
that is available in the runner toolcache. For Advanced Setup workflows,
the value provided for <code>tools</code> in the workflow definition
always takes precedence unless the value of the repository property
starts with <code>!</code>. <a
href="https://redirect.github.com/github/codeql-action/pull/4037">#4037</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.2">2.26.2</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4051">#4051</a></li>
</ul>
<h2>4.37.3 - 22 Jul 2026</h2>
<p>No user facing changes.</p>
<h2>4.37.2 - 21 Jul 2026</h2>
<ul>
<li>The new address format for the <code>config-file</code> input that
was introduced in CodeQL Action 4.37.0 is now enabled by default. In
addition to the format described there, the <code>remote=</code> prefix
can now be used to explicitly indicate that the input refers to a remote
file. All previous input formats continue to be accepted as well. <a
href="https://redirect.github.com/github/codeql-action/pull/4023">#4023</a></li>
<li>The CodeQL Action can now make use of <a
href="https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries">configured
private registries</a> in Default Setup to retrieve CodeQL configuration
files from remote repositories that require authentication. This will
allow customers to store their CodeQL configuration in a single
repository that can then be referenced by Default Setup workflows in
other repositories. We expect to roll this and other, related changes
out to everyone in July. <a
href="https://redirect.github.com/github/codeql-action/pull/4007">#4007</a></li>
</ul>
<h2>4.37.1 - 16 Jul 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: Add a deprecation warning for
customers using CodeQL version 2.20.6 and earlier. These versions of
CodeQL were discontinued on 1 July 2026 alongside GitHub Enterprise
Server 3.16, and will be unsupported by the next minor release of the
CodeQL Action. <a
href="https://redirect.github.com/github/codeql-action/pull/3956">#3956</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.1">2.26.1</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4019">#4019</a></li>
</ul>
<h2>4.37.0 - 08 Jul 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.0">2.26.0</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/3995">#3995</a></li>
<li>In addition to the existing input format, the
<code>config-file</code> input for the <code>codeql-action/init</code>
step will soon support a new <code>[owner/]repo[@ref][:path]</code>
format. All components except the repository name are optional. If
omitted, <code>owner</code> defaults to the same owner as the repository
the analysis is running for, <code>ref</code> to <code>main</code>, and
<code>path</code> to <code>.github/codeql-action.yaml</code>. Support
for this format ships in this version of the CodeQL Action, but will
only be enabled over the coming weeks. <a
href="https://redirect.github.com/github/codeql-action/pull/3973">#3973</a></li>
</ul>
<h2>4.36.3 - 01 Jul 2026</h2>
<p>No user facing changes.</p>
<h2>4.36.2 - 04 Jun 2026</h2>
<ul>
<li>Cache CodeQL CLI version information across Actions steps. <a
href="https://redirect.github.com/github/codeql-action/pull/3943">#3943</a></li>
<li>Reduce requests while waiting for analysis processing by using
exponential backoff when polling SARIF processing status. <a
href="https://redirect.github.com/github/codeql-action/pull/3937">#3937</a></li>
<li>Update default CodeQL bundle version to <a

Subject: [PATCH 866/878] fix: Propagate NULLs in `regexp_count`,
 `regexp_instr` (#24239)

## Which issue does this PR close?

- Closes #24152

## Rationale for this change

`regexp_count` and `regexp_instr` should follow the behavior of these
functions in PostgreSQL and return NULL when any of their arguments is
NULL. The previous behavior was inconsistent: `regexp_instr` returned
NULL for a NULL string or pattern, but otherwise NULLs were treated as a
default value, returned a match count of 0, or raised an error,
depending on the context.

## What changes are included in this PR?

* Make NULL handling of `regexp_count` and `regexp_instr` consistent and
match PostgreSQL
* Update SLTs or add new SLTs / unit tests as necessary

## Are these changes tested?

Yes, new tests added and/or existing tests updated when necessary.

## Are there any user-facing changes?

Yes: the behavior of these UDFs has changed when called with NULL

Subject: [PATCH 867/878] fix(physical-plan): CTAS panic on
 wasm32-unknown-unknown (#24275)

## Which issue does this PR close?

- Closes #24274

## Rationale for this change

`CREATE TABLE ... AS SELECT` and `MemTable::load` panic on
`wasm32-unknown-unknown` in browser hosts using `wasm-bindgen-futures`.
Both route through `collect_partitioned`, which unconditionally calls
`JoinSet::spawn` which needs an active tokio reactor.
`wasm32-unknown-unknown` builds typically don't have one.

## What changes are included in this PR?

- Adds a single-partition fast path to `collect_partitioned` that drains
the stream directly instead of using `JoinSet::spawn`
- Adds a `test_create_table_as_select` regression test to
`datafusion/wasmtest`, exercising the CTAS path both natively (via
`tokio::test`) and in the browser (via `wasm-pack test`).

Behavior for `partition_count != 1` is unchanged.

## Are these changes tested?

Yes

- Adds a CTAS query-level regression test to the `linux-wasm-pack` CI
job.
- Ran wasm-pack test suite on chrome:
- `RUSTFLAGS='--cfg getrandom_backend="wasm_js"' wasm-pack test
--headless --chrome datafusion/wasmtest`
- `cargo fmt --all`
- `cargo clippy --all-targets --all-features -- -D warnings`
- Full workspace extended-tests suite

## Are there any user-facing changes?

No API changes. On `wasm32-unknown-unknown`, `CREATE TABLE ... AS
SELECT` and `MemTable::load` no longer panic.

Subject: [PATCH 868/878] fix: preserve NULL semantics in `log` and `power`
 simplification (#24247)

## Which issue does this PR close?

<!--
We generally require a GitHub issue to be filed for all bug fixes and
enhancements and this helps us generate change logs for our releases.
You can link an issue to this PR using the GitHub syntax. For example
`Closes #123` indicates that this PR will close issue #123.
-->

- Part of #24246.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.

Please explain the problem you are trying to solve in terms of the
user-visible
behavior, rather than the implementation.

For example, "The code in `foo.rs` doesn't handle nulls" is a symptom of
the
implementation. "COUNT(DISTINCT) returns wrong results when the column
contains
nulls" is the user-visible problem.
-->

`log` and `power` simplifications removed a nullable base expression,
which could incorrectly produce a non-NULL result when the base was
NULL.

For example:

```sql
SELECT log(a, 1.0), power(a, 0.0)
FROM (VALUES (NULL::DOUBLE)) AS t(a);
```

These expressions should both return NULL, but simplification could
replace them with 0.0 and 1.0.

## What changes are included in this PR?

only apply these simplifications when the removed base expression is
non-nullable.

<!--
There is no need to duplicate the description in the issue here, but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

## Are these changes tested?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

If tests are not included in your PR, please explain why (for example,
are they covered by existing tests)?
-->

Yes. Added sqllogictests covering results and plans.

## Are there any user-facing changes?

Yes. log and power expressions with nullable bases now correctly
preserve NULLs.

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

If there are any breaking changes to public APIs, please add the `api
change` label.

Subject: [PATCH 869/878] fix: ensure new_list respects data_type argument
 (#24029)

## Which issue does this PR close?

- Closes #24022

## Rationale for this change

Fixes a bug where `ScalarValue::new_list`, `new_list_nullable`, and
`new_large_list` silently ignored the
`data_type` argument when the `values` array was non-empty. This caused
issues where accumulators like
`collect_list` could produce outputs with a slightly different type than
declared (e.g., in the nullability of
nested fields), leading to invalid argument errors in
`GroupedHashAggregateStream::emit`.

## What changes are included in this PR?

- Added a `cast_with_options` call for non-empty lists in
`ScalarValue::new_list`, `new_list_from_iter`, and
  `new_large_list`.
- Used `DEFAULT_CAST_OPTIONS` to ensure the concatenated array is
properly reconciled with the requested
  `data_type`.

## Are these changes tested?

Yes, this is covered by existing tests. It resolves the
`GroupedHashAggregateStream` output batch validation
failures for accumulators.

## Are there any user-facing changes?

No, this is an internal bug fix.

Writing larger row groups requires more memory to write, but can get better compression and be faster to read. When `max_row_group_bytes` is also set, the writer flushes a row group when either limit is reached, whichever comes first.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  |
 | datafusion.execution.parquet.max_row_group_bytes                        | NULL                      | (writing) Target maximum size of each row group in bytes. When set, the writer flushes whenever either this limit or `max_row_group_size` is reached, whichever comes first. Useful for bounding writer memory on wide schemas where a row-count limit can map to very different byte sizes. Matches the behavior of `parquet.block.size` in parquet-mr. If `None` (the default), only the row-count limit applies. Currently only honored when `allow_single_file_parallelism` is `false`; by default the parallel file writer ignores this limit.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

 details, including the per-variant size breakdown and benchmark

+### `ExecutionPlan::with_new_children` and `ExecutionPlan::with_new_children_and_same_properties` deprecated
+
+`with_new_children` and `with_new_children_and_same_properties` have been
+deprecated. These methods are used to replace the child plans of an
+`ExecutionPlan` while leaving the plan otherwise identical.
+
+`with_new_children_if_necessary` has also been deprecated in favor of
+`replace_children_if_necessary` for consistency in naming.
+
+As noted [here](https://github.com/apache/datafusion/pull/23332#discussion_r3554897693),
+while the addition of `with_new_children_and_same_properties` has the benefit
+of skipping potentially expensive computation in the case that replacement children
+have the same properties as the original children, it widens the API surface area
+of `ExecutionPlan` in a way that could be confusing for users.
+
+Thus, to rectify this, we unify these methods by introducing `replace_children`.
+`replace_children` solves this problem by taking `ReplaceChildrenOptions`,
+which includes a `ChildrenPropertiesMode`. The mode has two variants,
+`Keep` and `Recompute`, which tell `replace_children` whether plan
+properties can be reused or need to be recomputed.
+
+This method is called from `replace_children_if_necessary`, which is the
+standard entry point that should be used for replacing the children of a node.
+
+**Migration guide:**
+
+To migrate from `with_new_children` and `with_new_children_and_same_properties`
+to `replace_children`, it is recommended to implement `replace_children` with
+a `match` statement matching on the `ChildrenPropertiesMode`. In the case that
+the properties match the children, `ChildrenPropertiesMode::Keep`,
+follow the body of `with_new_children_and_same_properties`. In the case that
+the properties do not match the children, `ChildrenPropertiesMode::Recompute`,
+follow the body of `with_new_children`.
+
+For example, take a look at the implementation for `FilterExec`:
+
+```
+    fn replace_children(
+        self: Arc<Self>,
+        mut children: Vec<Arc<dyn ExecutionPlan>>,
+        options: ReplaceChildrenOptions,
+    ) -> Result<Arc<dyn ExecutionPlan>> {
+        validate_child_count!(self, children);
+        match options.children_properties {
+            ChildrenPropertiesMode::Keep => Ok(Arc::new(Self {
+                input: children.swap_remove(0),
+                metrics: ExecutionPlanMetricsSet::new(),
+                ..Self::clone(&*self)
+            })),
+            ChildrenPropertiesMode::Recompute => {
+                let new_input = children.swap_remove(0);
+                FilterExecBuilder::from(&*self)
+                    .with_input(new_input)
+                    .build()
+                    .map(|e| Arc::new(e) as _)
+            }
+        }
+    }
+```
+
+In the case that the options indicate the properties are the same, we can simply
+swap the children without having to recompute the properties. In the other case,
+we create a new node from scratch.
+
+To ensure that this works correctly, it is recommended that users also look
+through their codebase and ensure that they use `replace_children_if_necessary`
+for these changes — `replace_children_if_necessary` should be preferred over
+manual use of `replace_children`, since `replace_children_if_necessary` will
+call `replace_children` with the correct options filled in.
+
+See [PR #23903](https://github.com/apache/datafusion/pull/23903) for details.

Subject: [PATCH 875/878] [branch-55] fix wrong TopK results from re-reading
 already-delivered row groups (#24352) (#24368)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backport of #24354 to `branch-55` for the 55.0.0 release, per
@timsaucer's request in #22393.

## Which issue does this PR close?

- Backports the fix for #24352 (wrong TopK results from re-reading
already-delivered row groups).

## Rationale

#24352 is a **silent wrong-results** bug: with `pushdown_filters=true` +
TopK dynamic filter pushdown (both on by default), a row group whose
post-predicate selection is empty is finished by arrow-rs without
handing back a reader, so DataFusion's `rg_plan` trails the decoder
frontier by one and a later runtime prune rebuilds the decoder from a
stale plan — re-reading an already-delivered row group, duplicating rows
and dropping the true top-k tail. No error is raised.

This is a clean cherry-pick of the squashed #24354 commit (`574fe67`);
it applies to `branch-55` without conflicts.

## What changes are included?

`push_decoder.rs`: sync `rg_plan` to the decoder frontier via
`peek_next_row_group()` before each runtime prune/rebuild (gated on
`row_group_pruner.is_some()` so ordinary scans pay nothing), with a
defensive `internal_err!` if the frontier diverges from the plan. Plus
the slt + rust regression tests from #24354.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Backport of #24359 to `branch-55` for the 55.0.0 release, per
@timsaucer's request in #22393. Stacks cleanly on the already-merged
#24368 (#24354 backport).

## Which issue does this PR close?

- Backports the fix for #24355 — a second, independent silent
wrong-results bug in the same parquet dynamic row-group pruning path as
#24352.

## Rationale

With `pushdown_filters=true` + a TopK dynamic filter, the runtime
row-group pruner rebuilds the push decoder via
`into_builder().with_row_groups(...)`, which drops row groups **without
slicing** the carried flat page-index `RowSelection` to match — a
dropped RG's selectors are then applied to the next surviving RG,
silently returning wrong rows (no error). The fix declines to build the
runtime `RowGroupPruner` when a row selection is present (correctness
over the pruning optimization); the proper fix that keeps both is
tracked upstream in apache/arrow-rs#10624 / #24358.

## Notes

- Clean cherry-pick of #24359 onto `branch-55` (which now has #24354 via
#24368). No conflicts.
- #24359 is **approved** on `main` and pending merge; opening this now
so it can ride RC3.
- Verified locally on this branch: the full `dynamic_row_group_pruning`
rust module (9/9) and `dynamic_row_group_pruning.slt` pass; clippy
clean.
