On queue storage, admin::cancel_by_unique_key and cancel_by_unique_key_tx built every available ready row in a CTE and filtered by key afterwards.
The lane range didn't lead with the ready key's ring slot, so it read every retained ready row, completed jobs included.
A missing key cost a full scan, and the transaction variant held the caller's transaction while it ran.
It also had a correctness gap: it read running jobs from leases only. A job running on a receipt claim that hadn't been materialised into leases wasn't found, so it couldn't be cancelled by key.
Change
The key is filtered where each source is read:
Available: each lane is walked through ready_segments from its claim cursor, the way a claim finds rows, and probed along the ready key within each segment's ring slot. The probe is fenced with OFFSET 0, so the key filter can't flip the plan back to a full scan. When a queue is passed, only that queue's physical lanes are walked, from a separate SQL variant rather than a nullable OR.
Scheduled and retryable: the existing deferred_jobs unique-key index.
Running and waiting:leases, plus open receipt claims from open_receipt_running_claims_sql.
Cancellation itself still goes through the by-id path, so transaction and notification behaviour is unchanged.
One semantic edge:
A queue is part of a key only with by_queue, so a queue-scoped key means the job was enqueued in that queue.
A job moved to another queue while available isn't found by a lookup naming its original queue.
Scheduled, retryable, running and waiting jobs are found wherever they are, because those sources aren't queue-scoped.
Before this change, a scoped missing-key lookup paid for every queue's ready storage. Falling back to all queues would put that cost back.
Not in this PR: a partial ready_entries (unique_key) index.
A lookup with no queue still walks every queue's backlog. That's live work, not retained history.
New queue-storage tests in queue_storage_runtime_test:
cancel_by_unique_key_finds_each_live_state:
finds scheduled, available, running (receipt claim) and waiting-on-callback jobs, and a missing key returns nothing;
with two live jobs sharing a key, the oldest is cancelled first and the next call finds the newer;
a lookup without the queue doesn't match a by_queue key.
cancel_by_unique_key_tx_follows_the_callers_transaction: a rollback leaves the running job running, and on commit it's cancelled and its awa:cancel notice arrives.
cancel_by_unique_key_reads_live_work_only: rows read, taken from the backend's table statistics, stay flat with ten times the retained completions, for both scoped and unscoped lookups. A scoped lookup also stays flat beside another queue's 5,000-job backlog.
Against the previous lookup, all three fail: the running job isn't found, and a scoped missing-key lookup reads 726 rows, then 5,206.

queue_storage_runtime_test: 197/197.

#585)
On queue storage, cancel_by_unique_key and cancel_by_unique_key_tx built
every available ready row before filtering by key. The range didn't lead
with the ready key's ring slot, so it read every retained ready row,
completed jobs included, and a missing key cost a full scan while the tx
variant held the caller's transaction.
The key is now filtered where each source is read. Available rows are
walked lane by lane through ready_segments from the claim cursor, as
claims find them, and with a queue only that queue's lanes are walked.
Scheduled and retryable rows use the deferred unique-key index, and
running and waiting jobs come from leases and open receipt claims.
The lookup also missed running receipt claims not yet materialised into
leases, so a running job couldn't be cancelled by key; it now finds them.
Queue-storage tests cover each live state, oldest-first among jobs sharing
a key, the transaction variant's rollback and commit-time notice, and rows
read staying flat as retained completions and other queues' backlogs
grow. Against the previous lookup they fail: the running job isn't found,
and a scoped missing-key lookup reads 726 rows, then 5,206.

Walkthrough
Queue-storage unique-key cancellation now uses key-filtered candidate lookups with optional queue scoping. The lookup checks ready rows, deferred jobs, leases, and open receipt claims. Both cancellation entry points use it. Runtime tests cover candidate selection, transaction behavior, notifications, and lookup read scaling.

Summary
Candidate lookup and queue scoping awa-model/src/admin.rs, awa-model/src/queue_storage.rs
The lookup filters ready rows by key and can scope them to a logical queue’s physical queues. It also checks deferred jobs, leases, and open receipt claims. The lookup returns the lowest matching job ID.
Cancellation entry points awa-model/src/admin.rs
Both cancellation paths call the shared candidate lookup with the optional queue scope. The non-transactional path acquires a connection; the transaction-aware path uses the caller’s connection.
Runtime validation and documentation awa/tests/queue_storage_runtime_test.rs, CHANGELOG.md, skills/awa-jobs/SKILL.md
Runtime tests cover candidate types, oldest-match selection, transaction rollback and commit, notifications, and lookup read scaling. The changelog and job documentation describe lookup behavior and queue-scoped limitations.

Explanation
The changed paths support the unique-key cancellation fix. awa-model/src/admin.rs changes the queue-storage candidate lookup and the cancel entry points. awa-model/src/queue_storage.rs adds open_receipt_running_claims_sql_for, which the scoped lookup uses. The unscoped open_receipt_running_claims_sql keeps its previous behaviour. physical_queues_for_logical changes visibility only so admin.rs can call it. awa/tests/queue_storage_runtime_test.rs adds tests for the lookup. CHANGELOG.md and skills/awa-jobs/SKILL.md describe the changed lookup behaviour. No unrelated change is demonstrated. The PR objectives mention a separate job_output_test CI failure and the 0.6.10 release PR. Neither appears in the changed paths, so neither is counted as scope for this PR. The test-file diff was not readable, so test content is taken from the PR description and change summary.

Explanation
[#585] Partly met. Available lookup filters by key inside each ready-segment probe (awa-model/src/admin.rs, scoped_unique_key_candidate_sql and keyed_ready_rows_sql). Running work reads leases and open receipt claims by job_id. Scheduled and retryable work is not met for scoped lookups. The scoped deferred leg is SELECT job_id FROM deferred_jobs WHERE unique_key = $1, with no queue constraint. The has_ready_rows = false early return in queue_storage_unique_key_candidate also uses this unconstrained deferred read. #585 says: 'When supplied, constrain the available, deferred and running candidate branches to it.' The PR description records this as a deliberate semantic choice. That choice differs from the issue requirement, and no issue update is linked. Also missing: (1) No test covers completion racing cancellation. The listed tests cover live states, oldest-first selection, rollback and commit notification, and row-read scaling. #585 requires this case. (2) No query-plan evidence is reported. #585 asks for scoped and unscoped EXPLAIN or buffer inspection, including prepared or generic plans. The PR gives table-statistics row counts instead. The partial ready-row index is deferred. That decision depends on plan evidence the PR does not provide. Evidence limits: the admin.rs diff was truncated at 16000 bytes. The test-file diff could not be read because changed blobs are missing from the checkout. Test coverage is therefore taken from the PR description and the change summary.
Resolution
(1) In the scoped path, constrain the deferred_jobs candidate read and the has_ready_rows check to the physical queues in $2, as #585 requires. If cross-queue matching of scheduled and retryable jobs is intended, record that change in #585 with the reviewer's agreement, and document it in the function comment. (2) Add a queue-storage test where a completion commits between the key lookup and cancel. Assert that cancellation returns None and that the completed job is not changed. (3) Capture EXPLAIN (ANALYZE, BUFFERS) for scoped and unscoped lookups, with custom and generic plans, and attach the output to the PR. If the plans show a scan of unrelated ready storage, add the partial ready-row index with its migration and upgrade path. Otherwise, state the plan evidence that supports deferring it.

…ed ready rows (backport of #586)
On queue storage, cancel_by_unique_key and cancel_by_unique_key_tx built
every available ready row before filtering by key, reading every retained
ready row, and missed jobs running on receipt claims not yet materialised
into leases, so those couldn't be cancelled by key (#585).
The key is now filtered where each source is read: available rows are
walked lane by lane from the claim cursor through ready_segments (only the
given queue's lanes when a queue is passed), scheduled and retryable rows
use the deferred unique-key index, and running jobs come from leases and
open receipt claims. open_receipt_running_claims_sql is ported from main,
with the closed-claim-batch skip.
The queue-storage tests from #586 cover each live state, oldest-first
among jobs sharing a key, the tx variant's rollback and commit-time
notice, and rows read staying flat as history and other queues' backlogs
grow. Against the previous lookup they fail: the running job isn't found,
and a scoped missing-key lookup reads 720 rows, then 5,206.
Move the waiting job to waiting_external before cancelling it.
register_callback only stores the callback ID on the running lease. The job stays running. Only enter_callback_wait sets waiting_external. Call it after register_callback so this test covers cancellation of a waiting_external job, which the test name and issue #585 require.

&pool,
waiting,

Update the test flow using register_callback so registration is followed by
enter_callback_wait with the returned callback ID and the same lease, confirming
the transition succeeds before cancellation; retain the existing cancellation
assertions so the test covers a waiting_external job.
register_callback alone leaves the job running; enter the callback
wait so the test cancels a job in waiting_external. Note that the
open-receipt-claim leg of the candidate lookup costs claim-ring
retention, not job history.
Port of the #586 follow-up: enter the callback wait so the test
cancels a job in waiting_external, and note that the open-receipt-claim
leg costs claim-ring retention.
Rust tests (pg18, rest) failed on 9cac59c in job_output_test::external_completion_stores_the_output_it_is_given (job_output_test.rs:495: JobNotFound { id: 1 }). This PR doesn't touch that test or the completion and retention paths behind it. The same job passed on cab717e, and the same panic at the same line failed four recent main CI runs (61b65e5, 7a3db62, c76b995 and one earlier).
Cause: this is the race described on #572 for staged_follow_up_test. The test's client uses the default 1 s queue-storage ring rotation. After the external completion it calls client.shutdown(Duration::from_secs(2)), and maintenance can rotate the slot and prune the completed rows during that window. The following admin::get_job then finds nothing. In this file, only completion_stores_the_output_on_both_terminal_paths sets a long rotation.
Proposed fix (not in this PR): give the queue-storage clients in awa/tests/job_output_test.rs the long rotation that test already uses, preferably through a shared builder helper:
Given a queue, the lookup now reads that queue's ready rows holding the
key, one ring slot at a time along the ready key, and checks only those
jobs: available past the claim cursor and not tombstoned, in leases, or
on an open receipt claim found by job_id. With no such row only the
deferred_jobs key index can hold the key, so that query alone answers.
The previous lookup read every open receipt claim before filtering by
key. A long-running job keeps the claim ring from pruning; on the 0.6
line, 120,000 retained row-local claims made each lookup take about
9.7 s. With this change the same database answers in 1.7 ms for a
missing key and 11-20 ms to cancel a scheduled or available job.
The cost test also measures a lookup for a finished job's key and keeps
row-local claims retained.
ef512342 changes the queue-scoped lookup to start from the key. A production-scale benchmark on the 0.6 backport showed that the open-receipt-claims leg, which reads every claim still in the claim ring before the key filter, dominated once claims were retained. A long-running job keeps the claim ring from pruning. With 120,300 retained row-local claims and 180,200 retained ready rows in other queues, the earlier lookup took about 9.7 s, against 2.8 s for 0.6.9.
Given a queue, the lookup now:
reads that queue's ready rows holding the key, one ring slot at a time along the ready key (main has no (queue, …) ready index since v050);
checks only those jobs: available past the claim cursor and not tombstoned, in leases, or on an open receipt claim found by job_id;
answers from the deferred_jobs key index alone when the queue has no such row. That also skips planning the full lookup, about 10 ms across the partitioned tables.
On the same 0.6 data, measured through cancel_by_unique_key_tx and rolled back (p50 of 100): a missing key takes 1.7 ms; cancelling a scheduled job 11 ms; cancelling an available job 20 ms.
test_queue_storage_cancel_by_unique_key_reads_live_work_only now also looks up a finished job's key and retains row-local claims (claimed with a deadline). On the 0.6 branch the previous lookup fails it, reading 434 and then 32,912 rows. On main the previous lookup passed at the test's scale, so that regression is only demonstrated on 0.6. I haven't benchmarked main at production scale.
This supersedes the "claim-ring-bounded" note on the earlier CodeRabbit thread for queue-scoped lookups. Lookups without a queue still read the whole claim ring; that's #587.
Correct the cost statement for the compact-batch leg.
When a keyed ready row exists, the compact-batch leg of this helper reads every retained lease_claim_batches row in all claim slots. The leg has no index on job_ids, so batches.job_ids && {ids} cannot narrow that scan. The cost follows the retained claim-batch volume, not the number of requested jobs. The rows scanned are retained claim batches, not completed-job history. The doc comment should state this. The correction is documentation only, and no new index is needed.

Add an older waiting job that shares a key with a newer available job.
The shared-key case in test_queue_storage_cancel_by_unique_key_finds_each_live_state uses two available jobs. A lookup that checks available rows before waiting rows would still pass this test. Queue-storage runs do not cover a waiting job that is older than an available job under one key. The canonical-only integration test that covers this pair is skipped on queue storage. Add that pair and assert that the waiting job is cancelled first.

19492:
Extend test_queue_storage_cancel_by_unique_key_finds_each_live_state with an
older WaitingExternal job and a newer Available job sharing the same unique key.
Put the older job into callback wait before enqueueing the newer one, then
assert cancel_unique selects and cancels the older waiting job while leaving the
newer available job unchanged.
Review follow-ups on the queue-scoped unique-key lookup:
- Match leases by job_id, as open receipt claims already are. A job
moved to another queue while available is leased on its new lane, so
matching by its original ready row's lane missed it once it ran or
waited there.
- Read the ready-row check and the deferred_jobs lookup in one
statement, so a job promoted from deferred_jobs between two reads is
not missed by both.
- Say what the compact-batch leg of the job-restricted open-claims
query reads: every retained batch header, unnesting only batches that
hold one of the jobs.
New test: two jobs moved to another queue, one running on a receipt
claim and one waiting on a callback, are both found by a lookup naming
their original queue.
Map JobNotFound to Ok(None) on the queue-storage cancel paths.
If the selected job completes after lookup, queue-storage cancel returns JobNotFound. The canonical branch maps this error to Ok(None), as the documented contract requires. Apply the same mapping to the queue-storage branch in cancel_by_unique_key and to the queue-storage branch in cancel_by_unique_key_in_tx.

Scoped unique-key lookup still reads every retained claim batch header.
When the queue has a matching ready row, scoped_unique_key_candidate_sql runs the open-claims leg. That leg filters lease_claim_batches on batches.job_ids && ..., and no index covers job_ids. Each lookup therefore reads all retained batch headers, so its latency grows with claim-ring retention. Either add an access path for this filter or correct the doc comment at awa-model/src/admin.rs:1053-1056, which says the scoped cost does not follow the claim ring.

Add a positive unscoped cancel-by-key test for queue storage.
Add a positive unscoped cancel-by-key test for queue storage.
The queue-storage tests call cancel_by_unique_key without a queue at only one site, awa/tests/queue_storage_runtime_test.rs:19631. That call expects None for a by-queue key, which is correct. The other unscoped checks use absent or finished keys and assert only read bounds. No test expects a found candidate from an unscoped lookup. An implementation that returns None for every unscoped lookup passes the current tests.
Add a live job created with by_queue: false. unique_cancel_opts hardcodes by_queue: true, so build that job with its own options. Then assert that cancel_unique(&pool, None, <key>) returns the job. This closes the coverage gap in linked issue #585.

The test asserts that the job stays Running after the rolled-back cancel. It never reads the listener. The later loop returns on the first awa:cancel payload with a matching job_id. A notice sent by the rolled-back attempt would satisfy that loop. A regression that notifies outside the transaction would pass.

After `tx.rollback().await.unwrap()` in the test, add a bounded listener check

other jobs, and preserve the existing assertion that the rolled-back cancel
leaves the job in the `Running` state.
The admin store is rebuilt from the active schema name with the default
config, so the queue-scoped lookup probed only the default 16 ready-ring
slots and bound only the logical queue name. On a schema installed with
more slots it missed available, running and waiting jobs in the higher
slots, and on a striped queue it missed jobs in the queue#N lanes.
The slot probe now takes its range from the schema's queue_ring_state,
and the physical queues come from the schema's queue_lanes. A job that
finishes between the lookup and the cancel returns None on queue storage
too, as it does on the canonical engine. Two regression tests cover a
20-slot ring with rows in slot 16 and a two-stripe queue; both fail on the
previous lookup. The cancel_by_unique_key doc and the jobs skill now say
what the lookup reads.
…key cancel
The admin store is rebuilt from the active schema name with the default
config, so a queue-scoped unique-key lookup bound only the logical queue
name and missed available, running and waiting jobs in a striped queue's
queue#N lanes. The physical queues now come from the schema's queue_lanes.
A job that finishes between the lookup and the cancel made the
queue-storage branch return JobNotFound; it now returns None, as the
canonical engine does and the docs say.
Both predate 0.6.10. Port of the same fixes on main (#586); the new
striped-lanes test fails on the previous lookup.
* fix(queue-storage): let restricted runtimes use pre-provisioned lane sequences (0.6 schema patch)
Backport of #501 to the 0.6 line. The lane helpers and head-sync triggers ran
CREATE SEQUENCE IF NOT EXISTS even when the sequence existed, which requires
schema CREATE and defeats the documented migrator/runtime role split. They now
skip the DDL when the sequence exists and raise SQLSTATE 42501 with a
provisioning hint when it does not and the role lacks schema CREATE.
0.6 cannot add migration versions, so the change ships as the idempotent schema
patch prepared_lane_sequences: it redefines awa.install_queue_storage_substrate
and re-runs it for every installed queue-storage schema with its existing slot
counts and receipt mode (lease_claims or lease_claim_batches in
claim_ready_runtime). Fresh installs pick up the helper through v023.
v023 is split in two files so the patch embeds only the helper definition: the
default-schema installer, legacy fixups and schema_version row stay in
v023_install_default_queue_storage_substrate.sql, which V23_UP still appends.
The patch lint now skips the installer body, whose guarded ALTER/DROP TABLE
statements run only when the function is called.
Add QueueStorage::prepare_queue and `awa storage prepare-queue` to provision all
priorities, shards and stripes as the migrator.
* docs: restricted runtime roles, prepare-queue and sequence UPDATE grant
* docs: shorten the prepared-lane changelog entry
* fix(admin): read queue-storage dashboard counts from live work, not retained history
Backport of #580 and #581 to the 0.6 line.
On queue storage, admin::queue_overviews, state_counts and state_timeseries
built every current job through queue_storage_current_jobs_cte, whose
terminal_jobs branch expands each completion batch and joins it back to
ready_entries, so their cost grew with retained history. One production
deployment saw queue_overviews take 22 s, polled by an open admin
dashboard. queue_state_counts is not maintained once queue storage is
active, so it can't stand in.
- queue_overviews reads the live-work tables the worker gauges read, counts
available rows exactly per lane from its claim cursor, and takes
completed_last_hour from completion-batch sizes (less tombstoned members)
and completed done_entries rows.
- state_counts counts completions from batch sizes less tombstones, and
available rows per lane.
- state_timeseries bounds every source by the window before any join;
terminal rows come only from done rows and batches finalised within it.
- JIT is off for all three; compiling cost more than running.
Running keeps 0.6's leases-only definition.
* chore: prepare 0.6.10 release
* docs: grant sequence UPDATE in the pgroles example too
Lane cursors need UPDATE on their sequences for setval; the SQL grant
block already said so, the pgroles manifest did not.
* chore: bump async-trait to 0.1.92 for clippy's double_must_use
Rust 1.99's clippy flags the must_use that async-trait 0.1.89 puts on
the boxed future of Worker::perform. main already locks 0.1.92, whose
expansion passes; the 0.6 lockfiles follow it.
* ci: run the Playwright E2E job on ubuntu-24.04
ubuntu-latest now resolves to 26.04, where the pinned Playwright refuses
to install Chromium. main pins the job the same way.
* fix(serve): stop abandoned admin requests from holding database connections
Backport of #583.
When a client gives up on an admin request, the server drops it but
Postgres keeps running its query, and sqlx holds the connection until the
query ends. If the query then ended in an error, sqlx's release check
closed the connection with a hard close, which hangs on a TLS connection,
so the pool lost that slot for good (sqlx 0.8.6 here, as 0.9 on main).
awa serve now builds its pool with awa_ui::admin_pool_options and
admin_connect_options: a 60 s statement timeout as a startup option
(--statement-timeout / AWA_STATEMENT_TIMEOUT), a release hook that reads
an abandoned query's result and keeps the connection, and
client_connection_check_interval = 5s on Postgres 14+.
* Round sub-millisecond admin statement timeouts up to 1ms
* Round admin statement timeouts up from nanoseconds
* fix(queue-storage): replace only the lane helpers in the prepared-lane patch
The 0.6.10 prepared_lane_sequences patch re-ran
awa.install_queue_storage_substrate for every installed queue-storage schema.
The installer takes exclusive locks on hot tables such as leases and
deferred_jobs, rebuilds the head-sync triggers and scans retained ready
entries for backfills, all inside the migration transaction. Under live load
on a v0.6.9 database it stalled every worker and producer for 23 s and
deadlocked one enqueue.
The three lane helpers (ensure_lane_sequences and the two head-sync trigger
functions) now live in awa.refresh_lane_sequence_helpers(schema), as on main.
The installer calls it, so new schemas get the fixed helpers. On existing
databases the patch calls only the refresh, under the per-schema install
advisory lock. It takes no table locks and reads no queue rows: the same live
rehearsal applied it in 22 ms with no completion gap and no errors.
The applied probe now checks all three helpers and the refresh function. A
new test asserts the patch holds no relation lock on queue-storage objects,
and that the installer does.
* fix(admin): keep queue-storage dashboard reads off retained history (backport of #584)
A review of the #580/#581 backport found the last-hour completed count
scanning completion batches once per recent tombstone (5.4 s on a
production-sized fixture), and queue lag reading each lane's first row,
which hides an older job a queue move or priority aging appends behind
newer ones.
- Available counts walk each lane's segments from its claim cursor and
probe the ready key per segment; a range without the key's leading ring
slot scanned every retained ready row. They also yield the oldest
available run_at, which is the queue lag again, as in 0.6.9.
- The tombstone check expands each recent batch in a tombstoned lane once
and matches its members by hash.
- The timeseries reads its window's terminal rows with ready-key probes
instead of through terminal_jobs, which joined them to every ready row.
- DLQ retry, purge and move invalidate the dashboard caches, as job
mutations already do (from #579).
admin_read_cost_test serves every polled endpoint against ten times more
retained history and fails if a read does more work; on the previous head
it fails for /api/queues and the timeseries.
* fix(admin): find unique-key cancel candidates without scanning retained ready rows (backport of #586)
On queue storage, cancel_by_unique_key and cancel_by_unique_key_tx built
every available ready row before filtering by key, reading every retained
ready row, and missed jobs running on receipt claims not yet materialised
into leases, so those couldn't be cancelled by key (#585).
The key is now filtered where each source is read: available rows are
walked lane by lane from the claim cursor through ready_segments (only the
given queue's lanes when a queue is passed), scheduled and retryable rows
use the deferred unique-key index, and running jobs come from leases and
open receipt claims. open_receipt_running_claims_sql is ported from main,
with the closed-claim-batch skip.
The queue-storage tests from #586 cover each live state, oldest-first
among jobs sharing a key, the tx variant's rollback and commit-time
notice, and rows read staying flat as history and other queues' backlogs
grow. Against the previous lookup they fail: the running job isn't found,
and a scoped missing-key lookup reads 720 rows, then 5,206.
* Cover a waiting_external job in the cancel-by-key test
Port of the #586 follow-up: enter the callback wait so the test
cancels a job in waiting_external, and note that the open-receipt-claim
leg costs claim-ring retention.
* fix(migrate): count the lane patch applied only when every substrate has it
The prepared_lane_sequences probe checked the three helpers in awa only.
A custom queue-storage schema restored or prepared with the 0.6.9 helpers
passed once awa did, and a database whose only active substrate was a
custom schema could never pass. The probe now checks the refresh
function, the installer and the helpers of every installed substrate,
from the catalogs so a schema the migrating role cannot use is reported.
migrations::schema_patch_status names what each missing patch still has
to repair, and migrations::run_with_report returns the schema versions,
the migrations and patches applied, what each patch repaired or still
lacks, and storage routing before and after.
* fix(cli): make awa migrate safe to run for the 0.6.10 patch
- Refuse --from, --to and --version when applying; they only select a
range to render, and the apply path always migrates fully.
- Wrap --sql output in one transaction that takes the migration
advisory lock, with ON_ERROR_STOP guidance in the header;
--no-transaction prints it bare for runners that own the transaction.
- Report the result: schema version, each patch and what it updated,
and storage routing before and after. Exit 1 when a patch is still
missing on some schema, naming it.
Tests cover the refused flags, a patch interrupted mid-run (nothing
applied, retry completes it) and exported SQL that fails under psql
with ON_ERROR_STOP and then applies cleanly.
* fix(queue-storage): provision lanes a 0.6.9 runtime created
A runtime role with schema CREATE owns the lane sequences it creates.
Provisioning such a lane as the owner (awa storage prepare-queue, the
first step of revoking runtime CREATE) failed with permission denied
for sequence: the head tables' BEFORE INSERT triggers run even for a
row ON CONFLICT DO NOTHING then skips, and they read and set the lane's
sequence. Lane inserts now skip rows that exist, under the same
per-lane advisory lock.
* test: rehearse the 0.6.9 -> 0.6.10 -> 0.6.9 upgrade as a release gate
Released 0.6.9 artifacts (the awa-cli and awa-pg wheels) install the
schema as an owner role and run a separate runtime role in a custom
queue-storage schema with the grants a working 0.6.9 deployment needs.
Over a banked backlog with retries, scheduled jobs and slow jobs in
flight, the candidate awa migrate patches under traffic, with no lock
above RowExclusive on any awa or queue-storage relation (one owner
transaction audit plus sampling during the real run), idle lanes at
their exact positions, live lanes only advancing, and routing
unchanged. Candidate and released workers then run together through
killed and restarted workers; the fleet rolls back to 0.6.9 (including
its awa migrate, which must leave the patch in place); privileges are
tightened as the owner and the released workers restart. Every job must
complete, retried jobs on a later attempt, with per-queue counts
matching what was enqueued.
CI runs it on PostgreSQL 17 and 18 alongside the other full-CI jobs;
release.yml already requires this workflow to pass on the tagged SHA.
Evidence is uploaded as JSON.
* docs: 0.6.9 -> 0.6.10 upgrade guide
One path: install the 0.6.10 CLI, run awa migrate once as the owner
under traffic, roll processes. States what does not need doing, what
the report means, how external runners apply the patch, how to roll
back (leave the patch installed), and the optional procedure for
revoking runtime CREATE, with a per-sequence grant because GRANT ON ALL
SEQUENCES fails on sequences a 0.6.9 runtime created.
* test: resolve a relative candidate CLI path against the workspace
cargo runs the rehearsal from awa/, so AWA_CANDIDATE_CLI=target/debug/awa
pointed at awa/target. Resolve it, and a relative CARGO_TARGET_DIR, from
the workspace root as the released-artifact paths already are.
* fix(admin): start a queue-scoped unique-key lookup from the key
The 0.6.10 lookup read every open receipt claim before filtering by
key. A long-running job keeps the claim ring from pruning, so on a
database with 120,000 retained row-local claims each lookup took about
9.7 s, worse than 0.6.9's 2.8 s on the same data.
Given a queue, the lookup now reads that queue's ready rows holding the
key through the lane index and checks only those jobs: available past
the claim cursor and not tombstoned, in leases, or on an open receipt
claim found by job_id. With no such row only the deferred_jobs key
index can hold the key, so that query alone answers, which also skips
planning the full lookup across partitioned tables (about 10 ms).
Measured on 180,200 retained ready rows and 120,300 claims in other
queues, through cancel_by_unique_key_tx rolled back: 1.7 ms for a
missing key, 11 ms and 20 ms to cancel a scheduled and an available
job (p50 of 100); 0.6.9's lookup took 2.8 s.
The cost test now also retains row-local claims; against the previous
lookup it reads 434 rows, then 32,912.
* fix(admin): find a moved running job by key, in one snapshot
Review follow-ups on the queue-scoped unique-key lookup:
- Match leases by job_id, as open receipt claims already are. A job
moved to another queue while available is leased on its new lane, so
matching by its original ready row's lane missed it once it ran or
waited there; 0.6.9 found it.
- Read the ready-row check and the deferred_jobs lookup in one
statement, so a job promoted from deferred_jobs between two reads is
not missed by both.
- Say what the compact-batch leg of the job-restricted open-claims
query reads: every retained batch header, unnesting only batches that
hold one of the jobs.
New test: two jobs moved to another queue, one running on a receipt
claim and one waiting on a callback, are both found by a lookup naming
their original queue.
* Hide the storage transition card once the transition is finalized
The runtime page showed the card on every cluster running queue storage,
long after the cutover finished. It now appears only while an engine is
prepared or a mixed transition is in flight.
* test: keep completed rows past ring rotation in telemetry tests
test_failure_path_metrics_reach_prometheus timed out waiting for its three
completed jobs: with the default one-second ring rotation, maintenance can
prune completed rows before the test counts them. The failure-path and
dashboard tests, which both count completed jobs, now build their clients
with a one-hour queue and lease rotation, as #588 did for the job output
tests on main.
* test(rehearsal): accept a fail_once job whose first attempt died with its worker
The rehearsal failed on PostgreSQL 17 with "fail_once job 331 never
retried". A worker killed after claiming a fail_once job but before its
handler returns leaves no Retry event; heartbeat rescue then runs attempt 2,
which completes as designed. The accounting now requires a Retry event only
when attempt 1 started on a worker that survived, and still requires every
fail_once job to complete on attempt 2 or later.
* fix(admin): find striped lanes and tolerate a finished job in unique-key cancel
The admin store is rebuilt from the active schema name with the default
config, so a queue-scoped unique-key lookup bound only the logical queue
name and missed available, running and waiting jobs in a striped queue's
queue#N lanes. The physical queues now come from the schema's queue_lanes.
A job that finishes between the lookup and the cancel made the
queue-storage branch return JobNotFound; it now returns None, as the
canonical engine does and the docs say.
Both predate 0.6.10. Port of the same fixes on main (#586); the new
striped-lanes test fails on the previous lookup.
* docs(0.6.10): external-runner patch check, absolute upgrade-guide link, release date
A runner that tracks only schema versions sees nothing new in 0.6.10, and
the exported patch skips queue-storage schemas the running role cannot use
without failing. The upgrade guide now says to add the R__ script, run it as
the owner and confirm with awa migrate --sql --pending. The CHANGELOG links
the guide absolutely so the link works in the GitHub release body.

Closes #585.
Problem
On queue storage,
admin::cancel_by_unique_keyandcancel_by_unique_key_txbuilt every available ready row in a CTE and filtered by key afterwards.It also had a correctness gap: it read running jobs from
leasesonly. A job running on a receipt claim that hadn't been materialised intoleaseswasn't found, so it couldn't be cancelled by key.Change
The key is filtered where each source is read:
ready_segmentsfrom its claim cursor, the way a claim finds rows, and probed along the ready key within each segment's ring slot. The probe is fenced withOFFSET 0, so the key filter can't flip the plan back to a full scan. When a queue is passed, only that queue's physical lanes are walked, from a separate SQL variant rather than a nullableOR.deferred_jobsunique-key index.leases, plus open receipt claims fromopen_receipt_running_claims_sql.Cancellation itself still goes through the by-id path, so transaction and notification behaviour is unchanged.
One semantic edge:
by_queue, so a queue-scoped key means the job was enqueued in that queue.Not in this PR: a partial
ready_entries (unique_key)index.Validation
New queue-storage tests in
queue_storage_runtime_test:cancel_by_unique_key_finds_each_live_state:by_queuekey.cancel_by_unique_key_tx_follows_the_callers_transaction: a rollback leaves the running job running, and on commit it's cancelled and itsawa:cancelnotice arrives.cancel_by_unique_key_reads_live_work_only: rows read, taken from the backend's table statistics, stay flat with ten times the retained completions, for both scoped and unscoped lookups. A scoped lookup also stays flat beside another queue's 5,000-job backlog.Against the previous lookup, all three fail: the running job isn't found, and a scoped missing-key lookup reads 726 rows, then 5,206.
Also run:
