Unsupported capabilities should throw clearly instead of silently downgrading. - New durable job runtime roles are separated: `IJobClient` submits and returns `JobHandle`, `IJobMonitor` queries state, `IJobRuntimeStore` persists runtime state, and `IJobWorker` claims and executes queued jobs. Job types persist stable registry names via `IJobTypeRegistry` / `.Jobs.Register(name)`, not assembly-qualified names. diff --git a/docs/guide/messaging-jobs-redesign.md b/docs/guide/messaging-jobs-redesign.md index 7bd16a2b6..dd7e2f784 100644 --- a/docs/guide/messaging-jobs-redesign.md +++ b/docs/guide/messaging-jobs-redesign.md @@ -14,12 +14,12 @@ services.AddFoundatio() .MapQueue("orders") .MapTopic("order-events", typeof(IOrderEvent)) .UseSubscriptionIdentity("billing-service")) - .UseInMemory() + .UseInMemory() .Jobs.UseInMemoryRuntime() .Jobs.Register("search.rebuild"); ``` -Application code should depend on `Foundatio.Messaging.IQueue`, `IPubSub`, `IJobClient`, `IJobMonitor`, and `IJobWorker` instead of constructing `InMemoryMessageTransport`, `MessageQueue`, `PubSub`, or `JobClient` directly. +Application code should depend on `Foundatio.Messaging.IQueue`, `IPubSub`, `IJobClient`, `IJobMonitor`, and `IJobWorker` instead of constructing `InMemoryMessageTransport`, `MessageQueue`, `PubSub`, or `JobClient` directly.

Smith" Date: Sun, 28 Jun 2026 00:01:12 -0500 Subject: [PATCH 11/94] fix: address messaging/jobs design-review feedback Durable jobs + CRON: - Add hosted JobRuntimeService that pumps occurrence materialization, due-dispatch, recovery, and queued-job execution (runtime previously never ran end-to-end). Register via AddJobRuntimeService(). - Enforce lease ownership in TryTransitionAsync (expectedNodeId) so a stale worker cannot overwrite the reclaiming node's terminal state. - Renew the claim on a heartbeat during execution and cancel the run when the lease is lost (RenewClaimAsync was dead code). - Strong, process-unique node identity (machine:pid:token). - Capped exponential CRON retry backoff (per-definition override). - Replace the hand-rolled cron parser with the vendored Cronos (moved into core Foundatio.Cronos); materialize every missed occurrence in the misfire window, not just the latest. Messaging: - Resilient consumer/subscription loops: a poison message or transient receive error no longer silently kills the consumer. - Fix in-memory push path double-settle (tolerate already-settled receipts in the safety-net abandon). - Honor visibility timeouts in the in-memory transport (reaper redelivers unsettled messages) so its advertised at-least-once guarantee is real. - Log handler exceptions instead of swallowing them. - Drop the misleading write-only content-type header. - Add ReceiveDeadLetteredAsync so poison payloads are inspectable. Conformance harness: - Replace silent capability skips with Assert.Skip. - Gate ordering assertions on the declared OrderingGuarantee. - Add visibility-timeout, competing-consumer, and DLQ-read scenarios. Tests cover lease-stomp rejection, manual ack, poison survival, multi-occurrence CRON, and the hosted runtime running a queued job.

Smith" Date: Sun, 28 Jun 2026 00:12:10 -0500 Subject: [PATCH 12/94] refactor: hoist shared MessageQueue/PubSub behavior into MessageClientCore (M1, M2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit M1 — remove the large duplication between MessageQueue and PubSub: - New internal MessageClientCore owns serialization, header/trace construction, routing-agnostic send, runtime-store scheduled dispatch, received-message creation with poison handling, auto/manual ack settlement, and the resilient consumer/subscription loop. - Unify the two near-identical handle classes into one MessageListenerHandle implementing both IMessageConsumer and IMessageSubscription. - Collapse the duplicated HandleMessageAsync overloads into a single generic method. - MessageQueue and PubSub become thin adapters mapping their option shapes onto the core. Fixes the prior drift: pub/sub subscriptions now also honor RedeliveryBackoff. M2 — enforce ITransportInfo.MaxBatchSize: oversized sends are split into chunks of at most MaxBatchSize (test via a fake transport). Behavior preserved — verified by the existing messaging, queue, and jobs suites plus the added chunking test.

Smith" Date: Sun, 28 Jun 2026 09:32:41 -0500 Subject: [PATCH 13/94] fix: address messaging/jobs design-review feedback (round 2) Close gaps surfaced in design review of the messaging/jobs redesign: - Prove redelivery-delay and lock-renewal: InMemoryMessageTransport now implements ISupportsRedeliveryDelay (timer-based re-enqueue that wakes a blocked receiver) and ISupportsLockRenewal (extends the in-flight visibility window), with conformance tests for both. - Make the attempt counter transport-independent: ReceivedMessage.Attempts reconciles DeliveryCount with the message.attempts header so store-backed redelivery can't reset the count and loop forever. - Real back-pressure: the pull loop is now a SemaphoreSlim-gated continuous dispatcher (per-message slot release, opportunistic batch claim) instead of a Task.WhenAll batch barrier, eliminating head-of-line blocking. - Core-owned metrics: foundatio.messaging.* and foundatio.jobs.* counters and histograms emitted on FoundatioDiagnostics.Meter. - Receive-side trace continuity: handlers run inside a Consumer Activity linked to the producer's traceparent/tracestate. - Configurable job cancellation polling (default 1s instead of fixed 50ms). - Document the IQueue namespace collision and the using-alias remedy. Add BasicQueueTransport test double (pull-only, opaque headers, no time-based capabilities) and repoint the unsupported-lock and redelivery-fallback tests at it, keeping fallback coverage and proving the attempt reconciliation end-to-end.

Smith" Date: Sun, 28 Jun 2026 22:13:00 -0500 Subject: [PATCH 14/94] feat: core-owned retry/dead-letter, Reject settlement, and per-source type demux Address messaging/jobs design-review feedback on the transport-backed messaging API. The transport stays a thin set of primitives; the core owns serialization, routing, retry, and dead-lettering so behavior is identical across transports. Settlement: replace IReceivedMessage.AbandonAsync/DeadLetterAsync with a single RejectAsync(RejectOptions) verb (Terminal/Reason/RedeliveryDelay). Terminal reject moves the message to the transport's native dead-letter sink, else a configured RetryPolicy.DeadLetterDestination, else drops (honest at-most-once) instead of throwing. Consumers: one receive loop per source that demultiplexes by message type, so multiple typed consumers can share a destination without mis-dispatch; same-type consumers compete round-robin. An unmatched type increments foundatio.messaging.unhandled, throws UnhandledMessageTypeException (isolated per message so the loop and other handlers survive), retries, and dead-letters as "no-handler" after a lenient budget. Retry policy: add RetryPolicy (MaxAttempts/Backoff/DeadLetterDestination/UnmatchedMaxAttempts/UnmatchedBackoff), configurable via Messaging.ConfigureRetry and overridable per consumer. The broker delivery count is the crash-safe attempt counter; no broker-native redrive config. Capabilities: add MaxDeliveryDelay/MaxRedeliveryDelay/MaxVisibilityTimeout to the delay/visibility capability interfaces so an over-limit delay routes through the durable runtime store instead of being silently truncated by the broker. Docs: rewrite settlement section and add 'core owns behavior' + 'retry and dead-lettering' guidance. Add 7 tests covering cap-routing, Reject, multi-type demux, unmatched dead-letter, core-managed DLQ, and default-tier MaxAttempts.

Smith" Date: Mon, 29 Jun 2026 00:04:43 -0500 Subject: [PATCH 15/94] feat: address messaging/jobs review feedback (pub/sub addressing, multi-type dispatch, job context, recovery, ownership, CRON) Pub/sub addressing: the transport receive source for a subscription is now the topic-qualified "{topic}/{subscription}" composite (exposed as IMessageSubscription.Source), so the same subscription identity on two topics stays isolated instead of colliding on a bare name. Multi-type dispatch: add IMessageTypeRegistry (stable name<->type, Type.FullName fallback, RegisterMessageType) as the single wire-discriminator authority; interface/base-routed consumers now resolve the concrete payload type from the message.type header and deserialize the actual type (assignable to the route type) instead of raw-envelope-only. Removes the orphaned MessageTypeResolver/UseMessageTypeName router API. Job execution context: IJobWithExecutionContext receives a JobExecutionContext (job id, attempt, store-backed progress, lease heartbeat, cancellation checks); remove the always-throwing ReportProgressAsync from IReceivedMessage. Non-CRON job recovery: the runtime pump reclaims plain jobs stuck in Processing past their lease via IJobRuntimeStore.GetExpiredProcessingAsync (excludes CRON occurrences) + a lease+owner-aware TryReclaimExpiredAsync (re-queue while attempts remain, else dead-letter), closing the renew race that could double-run a live job. Transport ownership: OwnsTransport flag so DI-built queue and pub/sub clients do not both dispose a shared singleton transport (the container disposes it once); direct construction still owns it. CRON: mark the legacy in-process AddCronJob/AddJobScheduler/ScheduledJobService path as legacy/compat with docs pointing to the durable runtime (full reroute deferred). Adds 8 tests (pub/sub isolation, interface concrete-deserialize, job context, stale recovery + reclaim guard + occurrence exclusion, DI dispose-once, delay cap routing) and updates the redesign guide. All messaging/queue/jobs tests pass; solution builds on net8 + net10.

Smith" Date: Mon, 29 Jun 2026 16:44:03 -0500 Subject: [PATCH 16/94] feat: add AWS SQS/SNS transport and make the conformance harness cross-transport Adds a temporary in-repo Foundatio.Aws provider (AwsMessageTransport over SQS/SNS) to validate the redesigned IMessageTransport contract against a real broker, plus the contract refinements that validation surfaced. Verified against LocalStack: 8 conformance tests pass, 5 skip for capabilities SQS lacks (priority, per-message expiration, push, transport-native dead-letter); in-memory conformance and the full messaging/queue/jobs suite remain green. Transport contract refinements driven by the AWS implementation: - TransportSendOptions.DestinationRole: the caller states queue vs topic so a transport routes without inferring (SNS publish vs SQS send). MessageClientCore sets it from the dispatch kind. - TransportMessage.ContentType: lets a text-native broker (SQS/SNS) store a text body (e.g. JSON) directly instead of base64; binary still base64s. - MessageDestinationStats: lifetime counters (Enqueued/Dequeued/Completed/Abandoned/Errors/Timeouts) are now nullable (null = not reported, e.g. SQS exposes no lifetime completed count); Queued/Working/Deadletter remain best-effort gauges. - ReceiptExpiredException documented as a best-effort, transport-specific signal (SQS delete is idempotent). - InMemoryMessageTransport now wakes a blocked receive when a visibility window lapses (reclaim timer), matching real brokers so the harness can long-poll uniformly. AWS provider: SQS queues + SNS topics/subscriptions (raw delivery + queue policy), capability max-bounds (15-min delay, 12h visibility/redelivery), well-known headers surfaced as native attributes for SNS filter policies, ResourcePrefix for run isolation, LocalStack docker-compose + README. Harness: whole-second timing windows, eventual-consistency-tolerant stats (gauges only), and capability/opt-in gating so the suite runs across in-memory and real brokers.

Smith" Date: Mon, 29 Jun 2026 17:05:23 -0500 Subject: [PATCH 17/94] Add Redis IJobRuntimeStore provider + cross-store conformance harness Validates the durable job runtime substrate against a real distributed store. RedisJobRuntimeStore implements all of IJobRuntimeStore using StackExchange.Redis transactions with hash-field conditions for optimistic concurrency (CAS), and a single Lua script for batch due-dispatch claiming. The reclaim path predicates on the exact observed lease value so a concurrent renew defeats a stale reclaim. Extracts a shared JobRuntimeStoreConformanceTests suite (in TestHarness) that both the in-memory reference and Redis run against the same invariants: state round-trips, optimistic transitions (status + node guards + patch application), leases/claims/steal-after-expiry, stale recovery excluding live leases and CRON occurrences (with the renew-during-reclaim race), scheduled-dispatch claim/complete/reschedule, and a contention test asserting exactly-one-winner for concurrent claims, transitions, and dispatch claiming. A FakeTimeProvider drives lease/expiry timing so the suite is fast and deterministic with no real sleeps. The Redis suite is gated on FOUNDATIO_REDIS_CONNECTION_STRING (skips when unset); each test isolates under a unique key prefix. Both suites: 6/6 green (Redis vs redis:7).

Smith" Date: Mon, 29 Jun 2026 17:21:40 -0500 Subject: [PATCH 18/94] Add Redis end-to-end integration tests: delayed-send fallback + CRON The conformance suite covers ScheduleDispatch/ClaimDueDispatches as primitives; these tests wire the real messaging core and CRON scheduler on top of the Redis IJobRuntimeStore and exercise the two paths the store exists to support: 1. A queue send whose delay exceeds the transport's MaxDeliveryDelay is routed into Redis (not truncated to the broker ceiling), stays time-gated (a drain before the due time claims nothing), and is pulled from Redis and handed to the transport once due. A within-cap delay still goes native and never touches the store. 2. CRON occurrences are materialized into Redis (Scheduled JobState + JobOccurrence dispatch), deduped by deterministic occurrence id, claimed and run to completion, retried-then-dead-lettered when they keep failing, and stale-reclaimed (via the Redis CAS reclaim) when an occurrence is stuck Processing under a dead node with an expired lease. Extracts a shared RedisTestConnection helper (gated on FOUNDATIO_REDIS_CONNECTION_STRING, unique key prefix per store) used by both the conformance and integration suites. Redis suite: 9/9 green (6 conformance + 3 integration) against redis:7; in-memory unaffected.

Smith" Date: Mon, 29 Jun 2026 19:50:43 -0500 Subject: [PATCH 19/94] Add Redis Streams message transport (at-least-once, ack/retry/dead-letter) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Pivots the Redis pub/sub work to Streams + consumer groups, the Redis primitive that actually supports ack/reject/retry (native pub/sub is fire-and-forget and can't redeliver). A stream is a queue/topic; a consumer group is a subscription — the default group for a plain queue gives competing consumers, one group per named subscription gives topic fan-out. RedisStreamsMessageTransport implements ISupportsPull, VisibilityTimeout, LockRenewal, RedeliveryDelay, DeadLetter, Provisioning, Stats and ITransportInfo (AtLeastOnce/Fifo) — the same capability set as the AWS SQS transport plus native dead-letter. XADD produces, XREADGROUP consumes, XACK+XDEL completes, and reclaim (abandon, redelivery delay, lock expiry, crashed consumer) is driven by a per-group lease: a sorted set scored by visible-until (unix-ms) plus a hash of owner-token|delivery -count. Because the lease lives in Redis, a message held by a crashed instance is recovered by any other instance; a stale receipt is detected by the owner token and surfaced as ReceiptExpiredException. Streams has no native per-message delay/priority, so those route through the runtime store / are unsupported (the contract's core owns that). Validation against redis:7: the cross-transport conformance suite runs 10/14 (push/priority/expiration/delayed-delivery skip via capability gates) and integration tests cover cross-instance crash recovery, the core's retry-then-dead-letter machinery driving the transport unchanged, and PubSub fan-out. Full Redis suite 22/22 green and stable; in-memory unaffected.

Smith" Date: Tue, 30 Jun 2026 00:02:23 -0500 Subject: [PATCH 20/94] Fix review P0 #1 (redelivery loop) + jobs runtime cluster MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adversarial contract review findings, batch 1: - P0 #1: runtime-store redelivery computed nextAttempt from the raw transport DeliveryCount, which resets to 1 on re-send for every real broker (SQS, Redis Streams) — pinning the carried attempts header at 2 and redelivering forever (never reaching MaxAttempts). Now advances from the reconciled Attempts. Masked by the in-memory transport, so added a regression test on a DeliveryCount-resetting transport that asserts attempts advance 1->2->3 (fails 3!=2 without the fix). - #3: CRON occurrences are now excluded from the generic worker (JobQuery.ExcludeOccurrences, applied in both stores; RunQueuedAsync sets it) so the scheduler is the sole executor; and a terminal occurrence's dispatch is retired (CompleteDispatchAsync) instead of rescheduled +1min forever. - #4: Redis TryClaimAsync now guards the lease-steal CAS on the exact observed leaseExpiresUtc (mirroring TryReclaimExpiredAsync), so a concurrent same-owner renew invalidates the steal — no double-run. Conformance Leasing test now covers renew-defeats-steal. - #14: PerNode SkipIfRunning scope match no longer uses a fragile JobId EndsWith(":{scope}") (the default node id contains ':'); it extracts the scope precisely past the fixed-width timestamp. - #15: clarified the two attempt-budget knobs (ad-hoc total-attempts vs scheduled retries). Jobs suites green: 18 in-memory + 6 Redis conformance.

Smith" Date: Tue, 30 Jun 2026 00:12:35 -0500 Subject: [PATCH 21/94] Fix review #6: auto-register the job runtime pump with the store MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A runtime store is inert without something draining it, yet UseInMemoryRuntime()/UseRuntimeStore() registered the store + processor but not the pump (it lived only behind a separate, undiscoverable AddJobRuntimeService() in the hosting package). The result: IJobClient jobs sat Queued forever and — worse — the messaging delayed-delivery fallback (which the same pump drains) silently disappeared. Move a JobRuntimePumpService (BackgroundService) into core and register it from RegisterJobServices, so configuring a store makes a hosted process run jobs and drain delayed messaging with no extra wiring; in a non-hosted process the IHostedService is simply never started. The hosting AddJobRuntimeService now carries its options onto the core pump instead of starting a second pump. This adds Microsoft.Extensions.Hosting.Abstractions (BackgroundService/ IHostedService) to the core package — a small, ubiquitous abstractions dependency, justified because the durable runtime is unusable without a pump. Flagging it for review; trivially revertible if you'd rather keep the pump exclusively in the hosting package. Tests: auto-registration + end-to-end run via the resolved pump; full jobs/queue/messaging regression green (201 pass, 4 pre-existing skips).

PubSub and the Redis transport now both use it instead of re-deriving. - AWS encodes any non-legal logical name (i.e. a subscription composite) into a legal, deterministic, collision-free SQS name (sanitize + stable hash suffix); legal names pass through unchanged. Fixed the comment that asserted the broken "already conforms" invariant. Tests: SubscriptionAddress round-trip (core); the Redis PubSub-facade fan-out integration test exercises the composite end-to-end. The AWS path can't be exercised without LocalStack here; the encoding is correct by construction. Messaging regression green (68 pass, 1 pre-existing skip); Redis suite 22/22.

Made send throw-on-failure normative: SendItemResult is now just the accepted MessageId, SendResult is the accepted ids, and the dead fields/branches are removed (core, JobScheduler materialize, conformance, all transports). Documented that a multi-message send is not atomic. #7: AWS and Redis each hand-rolled byte-for-byte-identical header JSON codecs with a latent case-semantics disagreement. Added a canonical MessageHeaders.SerializeToJson/DeserializeFromJson in core (bakes in the case-insensitive contract); both transports now use it. Added a round-trip test asserting case-insensitivity survives the wire. Regression green: messaging+queue 148 pass (3 pre-existing skips), Redis 22/22, in-memory transport 17 (1 skip).

Smith" Date: Tue, 30 Jun 2026 00:47:16 -0500 Subject: [PATCH 25/94] Fix review #11/#12: no-silent-skip conformance harness + coverage The conformance suites required each provider to re-declare every check as a [Fact] override, so a transport/store silently skipped any check the author forgot to override. Moved [Fact] onto the base virtual methods (MessageTransportConformanceTests, JobRuntimeStoreConformanceTests): concrete subclasses inherit and auto-run them, so a newly added base check runs against every provider with nothing to forget. Removed the redundant overrides from all subclasses (in-memory, AWS, Redis transport; in-memory + Redis store). Capability-unsupported checks self-skip via the base ISupports* gates; the one genuine provider opt-out (SQS DeleteMessage is idempotent, so the strict expired-receipt check) is now an explicit, visible Assert.Skip override rather than a silent omission. Added coverage (#12): a binary-body + case-insensitive-header round-trip conformance test that auto-runs on every provider (would catch a body/header codec divergence such as text-vs-base64). Verified discovery: in-memory transport 18 (15 conformance + 3 unit), Redis Streams 15 discovered / 11 run / 4 self-skip, AWS 16 discovered (skip without LocalStack), job-store conformance 6 on both stores.

Smith" Date: Tue, 30 Jun 2026 07:37:44 -0500 Subject: [PATCH 26/94] Add opt-out for the auto-registered job runtime pump Follow-up to the core-pump decision: the pump auto-starts under a host (so a configured store can't silently fail to drain), but advanced callers may want manual control (drive the processor/worker themselves, or run the pump on only some nodes). Adds JobRuntimePumpOptions.Enabled (default true); when false the hosted service is still registered but does nothing. Reachable from both wiring paths: - core: AddFoundatio().Jobs.ConfigureRuntimePump(o => o.Enabled = false) - hosting: AddJobRuntimeService(o => o.Enabled = false) (maps onto the core pump options) Safe default preserved; test asserts a disabled pump leaves a submitted job Queued and never runs it.

Two low-severity cleanups it surfaced: - Double-pump guard was order-dependent: calling AddJobRuntimeService before UseRuntimeStore registered both the hosting JobRuntimeService and the core JobRuntimePumpService against one store (each guard only checked for its own type; core can't see the hosting type across the package boundary). Collapsed to a single auto-registered pump: AddJobRuntimeService now only carries its options onto the core pump and never starts a second one, so any call order yields exactly one pump. (Not a correctness bug — claim/CAS prevented double-run — just redundant polling.) Added a hosting-first-order regression test. - Removed an orphaned `using System.Text.Json;` in the Redis Streams transport (left by the #7 header-codec move). Also hardened two poll-driven Redis integration tests (15s -> 30s): they flaked once under full-suite concurrency (many conformance tests hammer the same Redis); pass consistently with more headroom. Full matrix green: Foundatio.Tests 2001 (14 skip), Redis 27/27 (4 capability skips), AWS skips cleanly.

Messaging runs on AWS SQS/SNS (LocalStack) and durable jobs on Redis; the transport is config-selectable (Messaging:Provider = Aws | Redis) without touching any queue/pub-sub code. Extends the existing Aspire AppHost with a LocalStack container and 3 replicas of the service so the distributed behavior is directly observable in the dashboard logs. Smoke-tested standalone against Redis: order consumed, announcement received, report job completed (progress 100), heartbeat ticked. Both solutions build; the sample is registered in Foundatio.slnx and Foundatio.All.slnx.

Smoke-tested against Redis: heartbeat and refresh-cache both fire (materialized via the misfire window at startup).

Smith" Date: Wed, 1 Jul 2026 11:49:28 -0500 Subject: [PATCH 31/94] Isolate legacy message bus into Foundatio.Messaging.Legacy namespace Move the legacy IMessageBus surface (IMessageBus/IMessagePublisher/ IMessageSubscriber, MessageBusBase, InMemory/Null bus, Message, Shared/InMemory options) into Foundatio.Messaging.Legacy so it no longer collides with the redesigned messaging contract (IMessageTransport/IQueue/ IPubSub) that keeps the Foundatio.Messaging namespace. Referencers that still consume the legacy bus (HybridCacheClient, CacheLockProvider, WorkItemJob, the DI extensions, the hosting scheduled-job services, and the test harness/tests) gain a `using Foundatio.Messaging.Legacy;`. Repoint the Xunit logger-base doc crefs at the new IPubSub.SubscribeAsync{T}. No behavior change: full solution builds clean; the in-memory messaging, hybrid-cache, lock, and work-item-job suites stay green (448 passed, 1 skip).

Smith" Date: Wed, 1 Jul 2026 12:02:04 -0500 Subject: [PATCH 32/94] Isolate legacy job types into Foundatio.Jobs.Legacy namespace Move the legacy job surface (JobRunner, JobBase/JobContext, JobOptions, IQueueJob/QueueJobBase/QueueEntryContext, JobWithLockBase, JobAttribute, and the WorkItemJob family) into Foundatio.Jobs.Legacy so the redesigned durable- jobs API (IJobRuntimeStore/IJobClient/IJobWorker/IJobScheduler, JobState, ScheduledJobDefinition, JobExecutionContext) owns a clean Foundatio.Jobs surface. IJob.cs is split: the shared IJob contract, the new IJobWithExecutionContext, and the shared TryRunAsync helper (used by the new JobWorker) stay in Foundatio.Jobs; the legacy IJobWithOptions and the continuous-run RunContinuousAsync extensions move to Foundatio.Jobs.Legacy (LegacyJobRunExtensions). Referencers that still consume the legacy job types (the hosting job infra, the test-harness job/queue fixtures, and the job tests) gain a `using Foundatio.Jobs.Legacy;`. No behavior change: full solution builds clean; the Jobs test namespace stays green (56 passed, 1 manual-only skip).

Smith" Date: Wed, 1 Jul 2026 12:07:53 -0500 Subject: [PATCH 33/94] Isolate legacy hosting job infra into Foundatio.Extensions.Hosting.Jobs.Legacy MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the legacy in-process hosting job types — JobManager/IJobManager, the HostedJobService runner, the in-process ScheduledJobService CRON scheduler and its ScheduledJobInstance state, Cron, DynamicJob, and the HostedJob/ScheduledJob options+builders+registration — into Foundatio.Extensions.Hosting.Jobs.Legacy. Split JobHostExtensions: the new durable-runtime entry point (AddJobRuntimeService) stays in Foundatio.Extensions.Hosting.Jobs; the legacy registration API (AddJob/AddCronJob/AddDistributedCronJob/AddJobScheduler/ AddJobLifetimeService) moves to LegacyJobHostExtensions in the .Legacy namespace. The one durable-runtime bridge, JobRuntimeService, also stays. No external consumers referenced the legacy hosting types or DI methods, so the only fixups were an internal cref. No behavior change: full solution builds clean; the Jobs test namespace stays green (56 passed, 1 manual-only skip).

Every run is handed its context (cancellation token, job id, attempt, and store-backed progress/heartbeat helpers) and uses what it needs — no separate IJobWithExecutionContext marker to remember. JobExecutionContext gains a public "detached" constructor so a job can be run outside the durable runtime (tests, one-off invocations); its store-backed helpers become no-ops there. Because the old IJob (RunAsync(CancellationToken)) was shared with the legacy job system, legacy is forked onto its own self-contained contract: Foundatio.Jobs.Legacy gains its own IJob and its own JobResult/JobResultExtensions, plus a legacy TryRunAsync. The legacy job types, hosting runners, and legacy tests bind to those (dropping the now-ambiguous `using Foundatio.Jobs;`), leaving the new Foundatio.Jobs surface clean. Full solution builds (net8.0 + net10.0, warnings-as-errors); Jobs test namespace green (56 passed, 1 manual-only skip). Sample jobs updated to the new signature; the fuller sample rewrite (declarative handlers, fluent providers) follows.

Smith" Date: Wed, 1 Jul 2026 13:53:41 -0500 Subject: [PATCH 36/94] Declarative message handlers + fluent provider/CRON registration; idiomatic sample MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Messaging handlers are now declarative: AddFoundatio().Messaging.AddQueueHandler() (competing consumers) and AddBroadcastHandler() (fan-out via a per-instance subscription), plus delegate overloads. Handlers implement IMessageHandler and are resolved from DI in a per-message scope; a single auto-registered hosted service starts and stops them. Programmatic StartConsumerAsync/SubscribeAsync remain for dynamic use. Fluent provider + CRON registration for clean, idiomatic startup code: - .Messaging.UseAws() (Foundatio.Aws) — SQS/SNS, binding ServiceUrl/Region/ResourcePrefix/ credentials from an "Aws" config section, overridable via a lambda. - .Messaging.UseRedis() / .Jobs.UseRedis() (Foundatio.Redis) — Redis Streams transport and Redis job runtime store, sharing one IConnectionMultiplexer (from DI or a connection string / the "Redis" configuration entry). - .Jobs.AddCronJob(cron, o => ...) — registers a durable CRON schedule (CronJobOptions for scope/overlap/etc.); the runtime pump schedules all registered definitions on start, so no manual IJobScheduler.ScheduleAsync call is needed. The Aspire sample is rewritten to this surface: one AddFoundatio() chain with UseAws() + declarative handlers + UseRedis() + AddCronJob<>(); the hand-written MessagingWorkers and the dynamic UseTransport switch are gone. New DeclarativeRegistrationTests cover handler hosting/dispatch (queue class, queue delegate, broadcast) and AddCronJob registration + pump scheduling. Full solution builds (net8.0 + net10.0, warnings-as-errors); in-memory suite green (2004 passed), live Redis suite green (27 passed).

Found by an adversarial review of the two prior commits (all findings low/medium). Full solution builds (net8.0 + net10.0, warnings-as-errors); declarative + jobs suites green.

Smith" Date: Wed, 1 Jul 2026 16:42:05 -0500 Subject: [PATCH 38/94] One IMessageBus: the caller's verb decides delivery, handlers are topology-free MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The primary messaging client is now a single IMessageBus with two verbs: SendAsync (a command / unit of work — exactly one handler instance across the fleet processes it) and PublishAsync (an event — each subscribing service receives one copy, its instances competing). Handler registration carries no topology decision: AddHandler(o => ...) replaces AddQueueHandler/ AddBroadcastHandler, wiring both a queue consumer (Send target) and a service-identity subscription (Publish target) for the type. PerInstance opts a handler into per-replica fan-out for published messages (cache invalidation, config reload); Subscription forms an independent named subscriber group. The underlying IQueue/IPubSub clients remain for advanced scenarios (pull receive, programmatic consumers); MessageBus is a facade over them, and DI registers it as the primary client. The interface takes the IMessageBus name from the legacy bus, so the remaining dual-namespace files flip to pure Foundatio.Messaging.Legacy (the builder's legacy compat methods use an alias) — same pattern as the IJob fork. Producer options are renamed to match the verbs: QueueMessageOptions -> MessageSendOptions, PubSubMessageOptions -> MessagePublishOptions. Because one type can now be both sent and published, transports segregate queue and topic namespaces: Redis Streams prefixes stream keys by role ("q:"/"t:") and the in-memory transport keys destinations the same way (subscriptions are queue-shaped destinations a topic fans into, mirroring SNS->SQS). Without this a same-named queue and topic shared one stream and cross-delivered. Sample rewritten to the new surface: endpoints inject IMessageBus and the verb reads as intent; the announcement handler demonstrates PerInstance. Tests: DeclarativeRegistrationTests now proves send/publish isolation on one type and once-per-service vs PerInstance across two simulated instances; a live Redis test proves the same isolation on Streams. Full solution builds (net8 + net10, warnings-as-errors); in-memory 2005 green; live Redis 28 green.

Smith" Date: Wed, 1 Jul 2026 17:19:02 -0500 Subject: [PATCH 39/94] IMessageBus is the one messaging abstraction: IQueue and IPubSub are gone MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit MessageBus is now a first-class client over a single MessageClientCore, not a facade: MessageQueue, PubSub, IQueue, IPubSub, and their option records are deleted. The surface is one interface — SendAsync/PublishAsync (+batches), ReceiveAsync (pull), and SubscribeAsync, where a subscription is one logical attachment listening on the message type's two delivery channels (its send destination and this subscriber's identity on its topic). One options type, MessageSubscriptionOptions, serves declarative AddHandler and programmatic SubscribeAsync alike. Semantics hardened per adversarial review of the previous commit: - Multiple handlers can attach to one message type (previously crashed at startup on a consumer-key collision): default consumer keys are unique per subscription, so handlers compete round-robin for sent messages while an explicit Key still opts into one shared group. - Each handler class is its own subscriber group ("{service}.{handler}" via SubscriptionQualifier), so every handler registered for an event receives its own copy of each published message — instead of handler classes nondeterministically competing for one service copy. - Redis Streams: completing/dead-lettering no longer XDELs entries on topic streams (one group settling first must not delete a publish for slower groups); ExistsAsync/DeleteAsync are role-aware (topology validation works, topic cleanup no longer leaks or hits the wrong stream, subscription delete destroys only its group); GetStatsAsync no longer creates phantom streams/groups when probing. - PerInstance subscription names are derived at subscription start, per provider, fixing the shared-"unique"-name flaw for multiple providers. - Legacy gets its own MessageBusException (Foundatio.Messaging.Legacy), so a pure-legacy consumer can catch the legacy bus's exceptions without importing the new namespace; the remaining seven dual-namespace imports are flipped to pure-.Legacy. Tests: multiple-handlers semantics (each gets published events, a send reaches exactly one), send/publish same-type isolation via one subscription, idempotent same-key registration (behavioral, not reference equality), and a live-Redis regression test that a publish completed by one group is still delivered to a slower group. Full solution builds (net8 + net10, warnings-as-errors); in-memory 2006 green; live Redis 29 green.

Smith" Date: Wed, 1 Jul 2026 20:10:12 -0500 Subject: [PATCH 40/94] Rename IReceivedMessage to IMessageContext MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The handler-facing type is the consumption context wrapping a message — payload plus delivery metadata (Attempts, headers) plus the operations valid during this delivery (Complete/Reject/RenewLock) — so name it that, matching the ecosystem convention (MassTransit ConsumeContext.Message) and rhyming with the jobs side, where a job runs with a JobExecutionContext. Handlers now read context.Message instead of message.Message; internal CreateReceivedMessage/ ReceivedMessage names follow suit, and handler parameters are named context. Mechanical rename; no behavior change. Full solution builds; in-memory 2006 green; live Redis 29 green.

Smith" Date: Wed, 1 Jul 2026 23:55:31 -0500 Subject: [PATCH 41/94] Remove pull receive from IMessageBus; harden the pull loop against sync-empty transports MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The bus contract is now exactly three ideas: Send, Publish, Subscribe. ReceiveAsync/MessageReceiveOptions were queue-residue no bus-level abstraction in the ecosystem carries (MassTransit/NServiceBus/Wolverine/Rebus are all handler-based) — and they were asymmetric, pulling only the send channel. Advanced pull consumption remains where it belongs, on the transport (IMessageTransport / ISupportsPull). Converting the pull-based tests to subscriptions exposed a real core hole: the pull loop trusted transports to honor MaxWaitTime, so a transport whose ReceiveAsync completes synchronously-empty ran the loop inline forever (the subscribe call never returned) or hot-spun. The loop now starts via Task.Run and sleeps out the remainder of the poll window after an early empty poll. Tests move to a MessageCollector helper over SubscribeAsync with manual ack (inspect + settle deliveries explicitly); the pull-only poison-payload test is deleted (the push-path equivalent already covers poison dead-lettering). Full solution builds; in-memory 2005 green; live Redis 29 green.

Smith" Date: Thu, 2 Jul 2026 00:49:35 -0500 Subject: [PATCH 42/94] Failure-path conventions: DeadLetterOn, proven retry defaults, DLQ forensics, topology logging MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From the messaging-conventions research (the strongest cross-library convergence points), all convention-over-config: better behavior with zero new required setup. Fail-fast exception classification — the escape hatch every mature stack independently grew (NServiceBus AddUnrecoverableException, MassTransit Ignore, Rebus IFailFastException, Wolverine's error DSL) distilled to one knob: MessageSubscriptionOptions.DeadLetterOn() / DeadLetterWhen predicate (per-subscription, overriding a RetryPolicy.DeadLetterWhen default). A matching failure dead-letters on attempt 1 with reason "unrecoverable:{ExceptionType}" instead of burning the whole attempt budget. Deserialization failures already never retried; that stays structural. Production-proven retry defaults: RetryPolicy.Backoff now defaults to DefaultBackoff — immediate first retry, then 10s/20s/30s (capped) with ±20% jitter, the curve mature stacks converged on. Policy-driven delays are best-effort (RejectOptions.BestEffortDelay): a transport that can't honor the delay redelivers immediately instead of failing the settle; explicit caller delays stay strict. MaxConcurrency=1 keeps its value but now documents why it deliberately diverges from libraries that default higher. Dead-letter forensics: terminal messages are stamped with a documented header contract (exception type/message/truncated stack, reconciled attempts, original destination, failed-at) on both native and fallback sinks, so a dead message is triageable with plain transport tooling. When a transport has no native sink and no destination is configured, the message now parks at the derived "{source}.deadletter" instead of being silently dropped. Failed attempts that will retry log WARN; the terminal decision logs ERROR. The in-memory transport's native dead-letter now honors the caller's (enriched) entry headers, matching Redis. Delivery semantics are never invisible: each subscription logs its effective topology (send destination, topic/subscriber group, concurrency, retry posture) at Info when it starts. Tests cover DeadLetterOn first-attempt dead-lettering, the global predicate, the forensics contract, the default backoff curve, derived-DLQ parking, and best-effort delay degradation. Full solution builds; in-memory 2011 green; live Redis 29 green.

MessageContext carries a logger for this. - The runtime-store retry fallback only serves queue-channel entries: a subscription-channel entry's Destination is the opaque topic-qualified address, and a queue re-send to that name would land where no subscription group reads. Policy (best-effort) delays on subscription channels degrade to immediate redelivery; explicit delays fail with a precise error. - The exhausted attempt count is recorded in a forensics-only header (message.dead_letter.attempts) instead of overwriting message.attempts, so a replayed dead-letter starts with a fresh retry budget; exception-less deaths (no-handler, unresolved-type) clear any stale exception forensics. - A handler that settles manually and then throws now logs a distinct "threw after settling" warning instead of a retry/dead-letter that the settle path will skip. - The unmatched-type path joins the WARN-while-retryable / ERROR-when-terminal convention (previously every retryable no-handler attempt logged ERROR via the loop), and the loop no longer double-logs UnhandledMessageTypeException. - LogSubscription logs the effective (clamped) concurrency; Key documents that shared-key subscriptions must configure identical failure policies; MessageBusOptions.RuntimeStore documents the pump requirement for hand-wired options.

Delayed redeliveries live only in the inner transport's timer (neither queued nor working), so the decorator tracks scheduled-redelivery markers with a small grace window — without this, WaitForIdle would report idle while a retry was pending. - Messaging.UseTestHarness() registers the harness and points the bus at its transport; the harness resolves the container's serializer/registry so typed accessors agree with the wire format. This makes the core-owned failure path directly assertable in user tests: a poison message's retries (Abandoned) and terminal dead-letter (reason + forensics headers) are recorded facts, not log lines.

Verified-and-rejected (no change): the wall-clock redelivery-marker grace and the settle-then-record ordering are unreachable races — the redelivery timer and the idle poller share the same timer queue/thread pool (FIFO ordering means the lateness that would delay the timer delays the pruning polls behind it), and the inner settle is fully synchronous so the recording enqueue has no yield point after it. Full solution builds; in-memory 2015 green.

Capabilities and limits (delayed delivery + ceiling, priority, expiration, ordering, batch and size limits) now live on a TransportCapabilities record that ITransportInfo returns per destination role, and every core send-path decision — native-vs- runtime-store scheduling, priority/TTL validation, size checks, batch chunking — asks for the role it is actually targeting. Transports that cannot honor a future DeliverAt now refuse it loudly instead of accepting and dropping it (AWS topic branch, Redis Streams), with a new conformance fact enforcing that contract, plus a core regression test proving a delayed publish on a queue-delay-only transport routes through the runtime store.

Smith" Date: Thu, 9 Jul 2026 18:22:43 -0500 Subject: [PATCH 49/94] One canonical DestinationAddress across the whole transport contract MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Destination identity was spread across bare strings, a separate DestinationRole on the send options, DestinationDeclaration Name/Role/Source triples, and the formatted "{topic}/{subscription}" SubscriptionAddress convention that transports re-parsed at receive/settle/delete time. The same subscription was even declared under two different names — the routing topology declared the bare subscription name while the runtime subscribe path declared the formatted string, so Redis consumer groups created by IMessageTopology.EnsureAsync and by SubscribeAsync would not have agreed. DestinationAddress (Name + Role + owning Topic for subscriptions) is now the one identity on every path: send, receive, subscribe, settlement entries, stats, dead-letter reads, and provisioning (declare/exists/delete). The role rides with the address, so TransportSendOptions.DestinationRole is gone, the SubscriptionAddress parse-and-prefix convention is deleted, transports derive physical names structurally (Redis groups are named by the bare subscription name scoped to the topic stream; AWS keeps EncodeResourceName(address.Key), so no physical resources change), and topology and runtime declarations are equal by construction. ScheduledDispatchState splits the overloaded Destination field into a typed address for message dispatches and JobName for CRON occurrences. New ProvisioningLifecycle conformance fact covers ensure/exists/idempotent-re-ensure/delete. (Review feedback #3.)

MessageSubscriptionOptions.Deliveries (flags: Sent | Published, default Both) states the intent: the default narrows to whatever channels the transport's SupportedRoles can serve (skipped channel logged at debug), an explicit single-channel request the transport cannot serve throws NotSupportedException, and a transport that can serve neither always throws. IMessageSubscription's channel properties are empty for unwired channels. (Review feedback #1.)

Smith" Date: Thu, 9 Jul 2026 18:36:57 -0500 Subject: [PATCH 51/94] Explicit topology modes: Ensure, Validate, or None MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Publishing and subscribing implicitly granted themselves topology administration — every publish ensured its topic, every subscribe created its subscription, IMessageTopology.ValidateAsync was registered but consumed nowhere, and an app on a locked-down broker had no supported way to run. MessageBusOptions.Topology (and Messaging.ConfigureTopology(...) in DI) now selects the policy: Ensure keeps today's create-on-use behavior and also ensures the declared topology at handler-host startup; Validate never creates — each destination is existence-checked once (cached) and a missing one fails loudly, with the declared topology validated at startup so a misprovisioned app stops at boot instead of erroring per send; None makes no topology calls at all. AWS's AutoCreateDestinations now also guards SNS topic creation (lookup + loud failure instead of CreateTopic when disabled); the explicit EnsureAsync provisioning path always creates, since that call is the administrative intent the option withholds from the data paths.

IJobRuntimeStore composes it, so existing providers are unchanged. Job state, leases, and cancellation stay one contract on purpose: transitions verify ownership atomically and splitting them would break the compare-and-set semantics correctness depends on.

IJobClient.EnqueueAsync(args) serializes the arguments through the runtime's ISerializer into JobState.Payload with the argument type's full name as the stored discriminator; the job reads them back with JobExecutionContext.GetArguments() (HasArguments to probe), which throws a descriptive error naming the stored discriminator when the payload is absent or unreadable. CRON schedules carry arguments too (ScheduledJobDefinition/CronJobOptions.Arguments, serialized into each occurrence), the detached test context accepts an arguments object directly, the Redis store round-trips the new fields, and the store conformance suite asserts the payload survives persistence.

Smith" Date: Thu, 9 Jul 2026 18:54:54 -0500 Subject: [PATCH 54/94] Job execution scopes, bounded worker concurrency, decoupled pump MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three execution-model fixes. (1) Every job run now executes inside its own async DI scope, owned for exactly the run — scoped services (DbContexts, units of work) resolve per execution and are disposed when it ends, instead of silently resolving as effective singletons from the root container. (2) The worker gains a bounded pool: JobWorker(maxConcurrency) / JobRuntimePumpOptions.WorkerConcurrency caps in-flight queued jobs per node (default 1 preserves per-node ordering); a slot frees as each job settles, and TryTransition-guarded claims make the parallelism double-run-safe. (3) The pump's scheduling cadence is decoupled from job duration: CRON materialization runs every poll while dispatch/recovery/execution run as one overlapped pass (at most one in flight, drained on shutdown), and the schedule processor now materializes delayed queue/pub-sub message dispatches BEFORE running job occurrences, so the messaging delayed-delivery fallback is never head-of-line blocked by a long job claimed in the same batch.

Smith" Date: Thu, 9 Jul 2026 19:00:42 -0500 Subject: [PATCH 55/94] Supervised lease renewal/cancellation loops; shared-Key policies compared by identity MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lease renewal and cancellation polling were fire-and-forget timers whose discarded tasks swallowed every exception: a store outage silently stopped renewals, the lease lapsed, another node reclaimed the job, and the still- running original double-executed its side effects. Both are now supervised async loops owned by the run — started with it, stopped and awaited when it ends. The renewal loop treats a clean "renewal denied" as lease lost (cancelling the run, as before) and now also treats renewal that keeps THROWING the same way once the lease window passes without one success; the cancellation poll loop rides through store failures since a missed poll only delays cooperative cancellation. Also closes the shared-Key policy-divergence footgun: subscriptions sharing a consumer Key form one competing group, and their RedeliveryBackoff / DeadLetterWhen delegates are now compared by identity instead of mere presence, so two members whose failure logic differs are rejected at subscribe time instead of settling the same message differently by receiver.

Configure with `.Messaging.ConfigureRouting(...)`; use `UseDefaultQueue(...)`, `UseDefaultTopic(...)`, `MapQueue(...)`, and `MapTopic(...)` as the normal path. `Destination`, `Source`, `Topic`, and `Subscription` are advanced operation overrides. -- Routing configuration also declares startup topology. `IMessageTopology.GetDeclarations()` returns configured queues/topics/subscriptions, `EnsureAsync()` creates them through `ISupportsProvisioning`, and `ValidateAsync()` checks that they already exist for apps without create permissions. Operation overrides are not included in topology declarations. -- Pub/sub topic routing and subscription identity are separate. Topic answers where an event is published; subscription answers the logical service/consumer group. Same subscription across instances means competing consumers; different subscriptions on the same topic fan out. `PubSubSubscriptionOptions.Key` is only the local duplicate-listener key. -- Raw/envelope paths make grouped/default routes usable: `queue.ReceiveAsync(...)`, `queue.StartConsumerAsync(Func)`, and `pubsub.SubscribeAsync(Func)`. Typed `ReceiveAsync` / `SubscribeAsync` remain the simple path. -- Listener startup returns handles: `StartConsumerAsync` returns `IMessageConsumer`; `SubscribeAsync` returns `IMessageSubscription`. Same-key duplicate registrations are idempotent only for the same handler/options; conflicting registrations throw. Use `RunConsumerAsync` or `RunSubscriptionAsync` only for blocking lifetime loops. -- Received-message settlement uses explicit verbs only: `CompleteAsync`, `AbandonAsync`, `DeadLetterAsync`, `RenewLockAsync`, and `ReportProgressAsync`. Unsupported capabilities should throw clearly instead of silently downgrading. -- New durable job runtime roles are separated: `IJobClient` submits and returns `JobHandle`, `IJobMonitor` queries state, `IJobRuntimeStore` persists runtime state, and `IJobWorker` claims and executes queued jobs. Job types persist stable registry names via `IJobTypeRegistry` / `.Jobs.Register(name)`, not assembly-qualified names. -- In-memory setup for the redesign is `services.AddFoundatio().Messaging.ConfigureRouting(...).UseInMemory().Jobs.UseInMemoryRuntime()`. +## Messaging and Jobs (current API) + +- One messaging client: `IMessageBus` in `Foundatio.Messaging`. The caller's verb decides delivery -- `SendAsync` is a command processed by exactly one handler instance across the fleet (competing consumers); `PublishAsync` is an event received once per subscribing service (a scaled service's instances compete), or by every instance when the subscription sets `PerInstance`. `SendBatchAsync` / `PublishBatchAsync` batch both verbs. Per-operation options: `MessageSendOptions` / `MessagePublishOptions` (priority, `Delay`/`DeliverAt`, TTL, correlation id, headers, `Destination`/`Topic` override). +- Handlers are topology-free. Implement `IMessageHandler` and register with `.Messaging.AddHandler(o => ...)`; a hosted service (`MessageHandlerHostedService`) starts them all and each message is dispatched in its own DI scope. `IMessageBus.SubscribeAsync` is the dynamic path and returns an `IMessageSubscription` handle. +- `MessageSubscriptionOptions` declares delivery intent: `Deliveries` (`MessageDeliveries.Sent`/`Published`/`Both`, default `Both`), `Subscription` / `SubscriptionQualifier` / `PerInstance` for subscriber-group identity, `MaxConcurrency` (default 1, preserves per-handler ordering), `MaxAttempts` / `RedeliveryBackoff` / `DeadLetterWhen` (+ `DeadLetterOn()` shorthand) retry overrides, `AckMode` (`Auto` default / `Manual`), and `Key` (subscriptions sharing a key form one competing group; their backoff/dead-letter DELEGATES are compared by identity, so share delegate instances). +- Routing is central: `.Messaging.ConfigureRouting(r => r.UseDefaultQueue(...).UseDefaultTopic(...).MapQueue(...).MapTopic(...).UseServiceIdentity(...).UseSubscriptionIdentity(...).UseConvention(...))`. Precedence: operation override > exact map > interface/base-type map > `MessageRouteAttribute` > configured default > convention > kebab-cased type name. +- Routing config doubles as topology declarations (`DestinationDeclaration` with a canonical `DestinationAddress` -- `ForQueue`/`ForTopic`/`ForSubscription`). `IMessageTopology` exposes `GetDeclarations()` / `EnsureAsync()` / `ValidateAsync()`. `.Messaging.ConfigureTopology(TopologyMode.Ensure | Validate | None)` picks whether the client creates missing destinations (default), only verifies they exist (throws at startup when missing), or never touches topology; the handler host applies the mode at startup. +- The CORE owns retry/dead-lettering identically on every transport: default `RetryPolicy` is `MaxAttempts` 5 with immediate-then-10s/20s/30s backoff (+/-20% jitter); configure via `.Messaging.ConfigureRetry(p => p with { ... })`. Dead-lettered messages go to the transport's native sink or a derived `"{source}.deadletter"` destination, stamped with `message.dead_letter.*` forensics headers (`KnownHeaders.DeadLetter*`). Never configure broker-native redrive policies. +- Message settlement: `IMessageContext` / `IMessageContext` with `CompleteAsync()`, `RejectAsync(RejectOptions)` (non-terminal = retry, optionally with `RedeliveryDelay`; `Terminal = true` = dead-letter with `Reason`/`Exception`), and `RenewLockAsync()`. Auto-ack is the default. +- Transports advertise role-aware capabilities: `ITransportInfo.GetCapabilities(DestinationRole)` returns `TransportCapabilities` (e.g. the AWS transport's queue role has a native 15-minute `MaxDeliveryDelay`; its topic role has none). Delays beyond a ceiling and store-parked retries fall back to the durable runtime store (`IScheduledDispatchStore`, satisfied by any `IJobRuntimeStore`) and are drained by the job runtime pump -- never silently truncated. +- Durable jobs: implement `IJob` (`Task RunAsync(JobExecutionContext context)`). `IJobClient.EnqueueAsync()` / `EnqueueAsync(args)` (typed payloads) returns a `JobHandle`; `IJobMonitor` queries state; `IJobWorker` executes with per-run DI scopes, bounded concurrency, and supervised lease renewal. `JobExecutionContext` gives `JobId`/`Attempt`/`CancellationToken`, `GetArguments()`, `ReportProgressAsync`, `RenewLeaseAsync`, `IsCancellationRequestedAsync`; its public constructor makes a detached context for tests. +- CRON: `.Jobs.AddCronJob("0 */6 * * *", o => ...)` with `CronJobOptions` (`Scope` Global/PerNode, `Overlap`, `MisfireWindow`, `MaxRetries`, `TimeZone`, typed `Arguments`). Scheduled automatically when the runtime pump starts. Tune the pump with `.Jobs.ConfigureRuntimePump(o => ...)` (`JobRuntimePumpOptions`: `Enabled`, `PollInterval`, `BatchSize`, `MaxJobAttempts`, `WorkerConcurrency`). +- Stable wire names: `.Messaging.RegisterMessageType("name")` and `.Jobs.Register("name")` so persisted discriminators survive assembly/namespace moves; unregistered types fall back to `Type.FullName`. +- Legacy APIs still ship under the `Foundatio.Messaging.Legacy` (old `IMessageBus`/`InMemoryMessageBus`) and `Foundatio.Jobs.Legacy` (`JobBase`, `QueueJobBase`, `JobWithLockBase`, `JobRunner`) namespaces for migration. Prefer the current API in new code. ## Core Interfaces | Interface | Purpose | In-Memory | Production | | --------- | ------- | --------- | ---------- | | `ICacheClient` | Key-value caching with TTL | `InMemoryCacheClient` | Redis, Hybrid | -| `IQueue` | FIFO message queuing | `InMemoryQueue` | Redis, SQS, Azure | -| `IMessageBus` | Pub/sub messaging | `InMemoryMessageBus` | Redis, Kafka, RabbitMQ, Azure | +| `IMessageBus` | Commands (`SendAsync`) + events (`PublishAsync`) over one client | `InMemoryMessageTransport` | Redis Streams, AWS SQS/SNS | +| `IJobClient` / `IJobMonitor` | Submit and observe durable background jobs | `InMemoryJobRuntimeStore` | `RedisJobRuntimeStore` | +| `IQueue` | Work-item queue (classic API) | `InMemoryQueue` | Redis, SQS, Azure | | `IFileStorage` | File storage abstraction | `InMemoryFileStorage` | S3, Azure Blob, Minio | | `ILockProvider` | Distributed locking | `CacheLockProvider` | Redis-backed | -| `IJob` | Background job processing | N/A | Hosted services | | `ISerializer` / `ITextSerializer` | Binary and text serialization | `SystemTextJsonSerializer` | MessagePack, JsonNet | | `IResiliencePolicy` | Retry, circuit breaker, timeout | `ResiliencePolicyBuilder` | N/A | ## DI Registration -All services are **singletons** (maintain internal state/connections).

Tests skip automatically for unimplemented optional interfaces or unavailable backends. ## Gotchas -- **Lock returns null**: `TryAcquireAsync` returns `null` when the lock cannot be acquired -- always guard with `is not null` before doing work. `AcquireAsync` throws `LockAcquisitionTimeoutException` instead of returning null. +- **Handlers registered per class get their own event copy**: `AddHandler` defaults the `SubscriptionQualifier` to the handler type name, so two handler classes on one event type EACH receive every published message. Set an explicit shared `Subscription` only when they should compete. +- **Shared subscription keys compare delegates by identity**: subscriptions sharing a `Key` must pass the SAME `RedeliveryBackoff`/`DeadLetterWhen` delegate instances -- a lambda recreated per subscription is rejected as a conflicting registration. +- **Do not configure broker redrive policies**: the core owns retry/dead-lettering (SQS `maxReceiveCount`, DLX, etc. would split authority and make behavior transport-specific). +- **A runtime store needs its pump**: the DI builder auto-registers `JobRuntimePumpService` with any runtime store, but in a non-hosted process (no generic host) nothing starts it -- drive `JobScheduleProcessor`/`IJobWorker` manually or nothing drains. +- **Delayed sends beyond transport ceilings need a runtime store**: e.g. > 15 min on SQS, or any delayed publish on SNS topics. Without a store the operation fails loudly rather than truncating the delay. +- **`WaitForIdleAsync` ignores store-parked work**: delayed sends/retries parked in the runtime store are not transport activity -- drain them via the job schedule processor before asserting. +- **Lock returns null**: `TryAcquireAsync` returns `null` when the lock cannot be acquired -- always guard with `is not null`. `AcquireAsync` throws `LockAcquisitionTimeoutException` instead of returning null. - **Dispose streams and locks**: `ILock` is `IAsyncDisposable` -- use `await using`. Streams from `GetFileStreamAsync` are `IDisposable` -- use `using var`. -- **Cache TTL floor**: Expiration values below 5ms are treated as already-expired and the key is silently removed. If you compute TTL dynamically (e.g., `expiresAt - now`), guard against near-zero values. -- **Cache `GetAsync` returns `CacheValue`**: Check `result.HasValue` before accessing `result.Value`. A missing key returns `HasValue = false`, not an exception. -- **Cache stampede (thundering herd)**: The cache-aside pattern (`Get` -> miss -> load -> `Set`) is vulnerable to stampedes when a popular key expires and many callers regenerate simultaneously. Use `CacheLockProvider` to serialize regeneration: acquire a lock keyed on the cache key, double-check the cache after acquiring, and only then call the backing store. See the [Cache Stampede Protection](https://foundatio.readthedocs.io/guide/caching.html#cache-stampede-protection) docs for the full pattern. -- **Queue auto-complete**: `QueueJobBase` auto-completes entries based on `JobResult` by default. Set `AutoComplete = false` only when you need manual `CompleteAsync()`/`AbandonAsync()` control. Manual `DequeueAsync` does NOT auto-complete. -- **GetQueueEntryLockAsync error handling**: If `GetQueueEntryLockAsync` returns `null`, the queue entry is abandoned. If it throws, the entry is also abandoned and a `JobResult.FromException` is returned. Use `TryAcquireAsync` (not `AcquireAsync`) in your override since the return type is `Task`. -- **Failure semantics depend on job type**: `JobResult` only has `IsSuccess` -- there is no separate "failed but don't retry" status. For **queue-processed jobs** (`QueueJobBase.ProcessQueueEntryAsync`, or setting `context.Result` in a `WorkItemJob` handler), a non-success result triggers `AbandonAsync`, which re-queues the entry and eventually dead-letters it after `Retries` is exhausted -- reserve `FailedWithMessage`/`FromException` for transient errors you want retried, and log + return `JobResult.Success`/`SuccessWithMessage(...)` for permanent errors to avoid a pointless retry loop. For **standalone/manual jobs** (`JobBase`, a one-off `RunAsync()`/`RunInConsoleAsync()` run, or scheduled/cron jobs via `Foundatio.Extensions.Hosting`), there is no built-in retry or dead letter queue -- a failed result just produces an error-level log, a non-zero exit code from `RunInConsoleAsync`, or a failed entry in the job run history. Returning `FailedWithMessage`/`FromException` there is correct even for permanent errors, since nothing inside Foundatio will retry it. -- **JobWithLockBase vs manual locking**: Use `JobWithLockBase` when the entire run must be single-instance (leader election). Use manual `ILockProvider.AcquireAsync` inside `JobBase` for finer-grained locking within a job. -- **JobContext.RenewLockAsync**: Call in long-running jobs (both `JobBase` and `QueueJobBase`) to prevent lock expiration mid-processing. -- **Register as singletons**: All infrastructure services (`ICacheClient`, `IMessageBus`, `IQueue`, `IFileStorage`, `ILockProvider`) maintain internal state and connections -- always register as singletons. -- **CacheLockProvider + IMessageBus**: `IMessageBus` is optional but recommended. Without it, lock release falls back to polling. With it, locks are released instantly via pub/sub notification. -- **In-memory for tests**: All in-memory implementations are functionally equivalent to production providers. Swap via DI for fast, isolated unit tests with no external dependencies. +- **Cache `GetAsync` returns `CacheValue`**: check `result.HasValue` before `result.Value`. A missing key returns `HasValue = false`, not an exception. +- **Cache stampede**: serialize regeneration of hot keys with `CacheLockProvider` (lock on the cache key, double-check after acquiring). See the [Cache Stampede Protection](https://foundatio.readthedocs.io/guide/caching.html#cache-stampede-protection) docs. +- **Register as singletons**: infrastructure services (`ICacheClient`, `IMessageBus`, `IFileStorage`, `ILockProvider`) maintain internal state and connections; the `AddFoundatio()` builder does this for you. +- **In-memory for tests**: in-memory implementations are functionally equivalent to production providers and run the same conformance suites -- swap via DI for fast, isolated tests. +- **Legacy name collisions during migration**: old and new APIs coexist (`Foundatio.Messaging.Legacy.IMessageBus` vs `Foundatio.Messaging.IMessageBus`; `Foundatio.Jobs.Legacy.IJob` vs `Foundatio.Jobs.IJob`).

There is exactly one retry authority (the core), never a tug-of-war between core policy and a broker-native redrive policy. -IReceivedMessage? received = await queue.ReceiveAsync(new QueueReceiveOptions { - Source = "orders-high-priority" -}); -``` +Every transport API takes the same canonical identity: `DestinationAddress` (`Name`, `Role` — `Queue`/`Topic`/`Subscription`/`Binding` — and, for subscriptions, the owning `Topic`; created via `ForQueue`/`ForTopic`/`ForSubscription`). `Key` is its opaque string form (`"{topic}/{name}"` for subscriptions), so the same logical destination can never be spelled two ways on the send path versus the provisioning path. -Grouped or default queues can be consumed through the raw envelope path: +Facts a transport advertises are **role-aware**: the core asks `ITransportInfo.GetCapabilities(DestinationRole)` and gets a `TransportCapabilities` record (`DelayedDelivery`, `MaxDeliveryDelay`, `Priority`, `Expiration`, `Ordering`, `MaxBatchSize`, `MaxMessageBytes`). Capabilities genuinely differ by role on real brokers — the AWS transport's queue role has a native 15-minute `MaxDeliveryDelay` (SQS `DelaySeconds`) while its topic role has no native delay at all. Anything not advertised is treated as unsupported: the core validates, falls back to the runtime store, or fails loudly — a broker never silently drops a requested behavior. -```csharp -IReceivedMessage? received = await queue.ReceiveAsync(new QueueReceiveOptions { - RouteType = typeof(IOrderMessage) -}); - -await queue.EnqueueBatchAsync(new object[] { - new OrderSubmitted(id), - new OrderCancelled(id) -}); -``` - -Consumers return handles and do not block unexpectedly: +## Setup ```csharp -await using IMessageConsumer consumer = await queue.StartConsumerAsync(HandleAsync); +services.AddFoundatio() + .Messaging + .ConfigureRouting(r => r + .UseServiceIdentity("billing") + .MapQueue("orders") + .MapTopic("order-events", typeof(IOrderEvent))) + .ConfigureRetry(p => p with { MaxAttempts = 5 }) + .ConfigureTopology(TopologyMode.Ensure) + .RegisterMessageType("order.submitted") + .UseInMemory() + .Messaging.AddHandler() + .Jobs.UseInMemoryRuntime() + .Jobs.Register("search.rebuild"); ``` -Use `RunConsumerAsync` when the desired behavior is a blocking lifetime loop. Starting the same consumer key with the same handler and options is idempotent; starting the same key with conflicting handler/options throws. +Swap providers by swapping one line: `.Messaging.UseRedis()` (Redis Streams), `.Messaging.UseAws()` (SQS/SNS), `.Jobs.UseRedis()`, or `.Messaging.UseTransport(...)` / `.Jobs.UseRuntimeStore(...)` for anything custom. Application code depends on `IMessageBus`, `IJobClient`, and `IJobMonitor`; deployment or admin code can depend on `IMessageTopology`. -### Multiple message types on one destination +`RegisterMessageType(name)` gives a type a stable wire discriminator so payloads survive assembly/namespace moves; unregistered types fall back to `Type.FullName` (never `AssemblyQualifiedName`). `.Jobs.Register(name)` does the same for persisted job types. -Several message types can share a single destination. Start one typed consumer per type; they attach to a single underlying receive loop that dispatches each message to the consumer registered for its type (read from the `message.type` header): +## Handlers -```csharp -await using var submitted = await queue.StartConsumerAsync(HandleSubmittedAsync); -await using var cancelled = await queue.StartConsumerAsync(HandleCancelledAsync); -// One loop on the shared destination. OrderSubmitted is dispatched to the first handler, OrderCancelled to the second. -``` - -Consumers that share a message type compete: each message is dispatched to one of them, round-robin. All consumers on one destination must agree on `MaxConcurrency` (it is a property of the shared loop). A message whose type has **no** registered consumer on this node is handled loudly — see [Unmatched message types](#unmatched-message-types). - -A consumer whose route type is an interface or base type is a **grouped** consumer and receives the concrete payload (assignable to that type), not raw bytes: +Handlers are topology-free. A handler implements `IMessageHandler` and is registered declaratively; it never decides queue-vs-topic — the sender's verb does: ```csharp -await using var all = await queue.StartConsumerAsync(HandleAnyAsync); -// HandleAnyAsync receives IReceivedMessage whose Message is the concrete OrderSubmitted / OrderCancelled. -``` +public class SendConfirmationHandler : IMessageHandler +{ + public Task HandleAsync(IMessageContext context, CancellationToken cancellationToken) + => _email.SendConfirmationAsync(context.Message.OrderId, cancellationToken); +} -The concrete type is resolved from the `message.type` header through `IMessageTypeRegistry` and deserialized as the actual payload type. The registry is the stable wire discriminator in both directions — register stable names for types that may move between assemblies/namespaces; unregistered types fall back to `Type.FullName` (never `AssemblyQualifiedName`): - -```csharp services.AddFoundatio() - .Messaging.RegisterMessageType("order.submitted"); + .Messaging.AddHandler(o => + { + o.MaxConcurrency = 4; + o.DeadLetterOn(); + }); ``` -The raw-envelope path (non-generic `ReceiveAsync(new QueueReceiveOptions { RouteType = ... })`) remains for callers that want the bytes without deserialization. - -## Pub/Sub - -Pub/sub follows the same type-driven publishing pattern: - -```csharp -await pubsub.PublishAsync(new OrderSubmitted(id)); - -await using IMessageSubscription subscription = await pubsub.SubscribeAsync(HandleAsync); -``` +Each message is dispatched to the handler in its own DI scope (scoped dependencies work), and a single auto-registered hosted service (`MessageHandlerHostedService`) starts every registered handler at app start and disposes them at shutdown. Throwing from `HandleAsync` triggers the core retry/dead-letter policy. Each handler class defaults to its own subscriber group (the `SubscriptionQualifier` is set to the handler type name), so every handler registered for an event type receives its own copy of each published message. -Topic routing and subscription identity are separate. The topic answers where the event is published. The subscription answers which logical service or consumer group receives it. Multiple instances using the same subscription compete on the same transport subscription; different subscriptions on the same topic receive fan-out copies: +For dynamic subscriptions, `IMessageBus.SubscribeAsync(handler, options)` returns an `IMessageSubscription` handle (`Key`, `Destination`, `Topic`, `Subscription`, `Source`); disposing it detaches the handler. -```csharp -services.AddFoundatio() - .Messaging.ConfigureRouting(r => r - .MapTopic("order-events", typeof(IOrderEvent)) - .UseSubscriptionIdentity("billing-service")); -``` +### Subscription options -Advanced operation overrides remain available: +A subscription listens on the type's two delivery channels — sent commands and published events — and `MessageSubscriptionOptions` declares its intent: -```csharp -await pubsub.PublishAsync(message, new PubSubMessageOptions { - Topic = "order-events-replay" -}); - -await using IMessageSubscription subscription = await pubsub.SubscribeAsync( - HandleAsync, - new PubSubSubscriptionOptions { - Topic = "order-events-replay", - Subscription = "billing-replay" - }); -``` +- **`Deliveries`** — `MessageDeliveries.Sent`, `Published`, or `Both` (default). A handler that only ever consumes commands (or only events) states that so no idle listener is wired — and so a queue-only or topic-only transport can serve it. The default `Both` quietly narrows to what the transport supports; explicitly requesting a single channel the transport cannot serve throws `NotSupportedException`. +- **`Subscription`** — the subscriber-group identity for published messages. Defaults to the service identity, so all instances of a service share one subscription and compete. **`SubscriptionQualifier`** distinguishes groups within one service (`"{service-identity}.{qualifier}"`). **`PerInstance`** gives every running instance its own unique subscription (cache invalidation, config reload) and is mutually exclusive with `Subscription`. +- **`MaxConcurrency`** — messages processed concurrently per instance. Default 1: the only default that preserves per-handler ordering, and each handler already gets its own concurrent stream (10 handlers = 10 parallel consumers). Raise it for I/O-bound, order-agnostic handlers. +- **`MaxAttempts`**, **`RedeliveryBackoff`**, **`DeadLetterWhen`** — per-subscription retry overrides; null inherits the default `RetryPolicy`. **`DeadLetterOn()`** is the by-type shorthand for `DeadLetterWhen` and composes (call once per exception type). +- **`AckMode`** — `Auto` (default) or `Manual`. +- **`RouteType`**, **`Destination`**, **`Topic`** — grouped/interface consumption and per-subscription route overrides. +- **`Key`** — consumer identity. Subscriptions sharing a `Key` on the same channel form one competing group and must configure identical failure policies; the backoff/`DeadLetterWhen` **delegates are compared by identity**, so share the same delegate instances — a lambda recreated per subscription is rejected as a conflicting registration. -`PubSubMessageOptions` mirrors queue send options where concepts overlap: priority, delay, TTL, correlation id, deduplication id, headers, and topic override. `PubSubSubscriptionOptions.Key` is only the local duplicate-listener key; `Subscription` is the transport consumer group identity. `PublishBatchAsync(IEnumerable)` supports heterogeneous event batches and groups sends by resolved topic. +Delivery semantics are never invisible: each subscription logs its effective topology (destination, subscriber group, concurrency, retry posture) once at subscribe time. -## Routing +## Routing and topology -Default route precedence is: +`IMessageRouter` resolves the queue destination and topic for a message type. The default router's precedence: ```text -operation override > explicit route map > interface/base-type map > MessageRouteAttribute > configured default/convention -``` - -`IMessageRouter` is shared by queues and pub/sub. Configure routes once with `MessageRoutingOptionsBuilder`: - -```csharp -services.AddFoundatio() - .Messaging.ConfigureRouting(r => r - .UseDefaultQueue("all-work") - .UseDefaultTopic("all-events") - .MapQueue("orders") - .MapQueue("orders", typeof(OrderSubmitted), typeof(OrderCancelled)) - .MapQueue("order-work", typeof(IOrderMessage)) - .MapTopic("order-events", typeof(IOrderEvent)) - .UseConvention(ctx => $"app-{ctx.MessageType.Name.ToLowerInvariant()}")); +operation override > exact type map > interface/base-type map > MessageRouteAttribute > configured default > convention > kebab-cased type name ``` -`QueueMessageOptions.Destination`, `QueueReceiveOptions.Source`, `PubSubMessageOptions.Topic`, and `PubSubSubscriptionOptions.Topic`/`Subscription` are final escape hatches for one operation. Attribute routing remains available for type-local defaults, but central routing should be the normal path. +Configure routes once with `ConfigureRouting` (a `MessageRoutingOptionsBuilder`): `UseDefaultQueue`, `UseDefaultTopic`, `MapQueue` / `MapQueue(destination, params Type[])`, `MapTopic` / `MapTopic(topic, params Type[])`, `UseServiceIdentity`, `UseSubscriptionIdentity`, and `UseConvention`. `UseServiceIdentity` names the service (the default subscriber-group identity); when unset it falls back to the `FOUNDATIO_SUBSCRIPTION_ID` / `FOUNDATIO_SERVICE_ID` environment variables, then the kebab-cased app name. -Routing configuration is also the topology declaration source. `UseDefaultQueue`, `UseDefaultTopic`, `MapQueue`, and `MapTopic` declare the queue destinations or topics they name; `UseSubscriptionIdentity` declares subscriptions for configured topics. Operation-level overrides are intentionally not part of startup topology because they are exceptional one-off routes. +**Routing configuration is also the topology declaration source.** `UseDefaultQueue`, `UseDefaultTopic`, `MapQueue`, and `MapTopic` declare the destinations they name, and setting a service/subscription identity declares the subscription on each configured topic — as `DestinationDeclaration` values carrying the *same* canonical `DestinationAddress` the runtime later sends to and receives from, so provisioning and runtime can never disagree on identity. Per-operation overrides are deliberately excluded: they are exceptional one-off routes. ```csharp IMessageTopology topology = provider.GetRequiredService(); IReadOnlyList declarations = topology.GetDeclarations(); await topology.EnsureAsync(); // deploy/admin process with create permissions -await topology.ValidateAsync(); // app startup check without creating destinations +await topology.ValidateAsync(); // check-only; throws naming what is missing ``` -## Delivery Settlement +`TopologyMode` (via `ConfigureTopology`) governs how the client administers topology at runtime and at startup: + +- **`Ensure`** (default) — create missing destinations on first use, and the handler host ensures the declared topology before any handler starts consuming. +- **`Validate`** — never create; verify each destination exists and throw when missing. Startup fails at boot instead of surfacing as runtime send errors. +- **`None`** — no topology calls at all; everything is pre-provisioned out of band. + +The mode governs the core's provisioning calls; combine `Validate`/`None` with transport knobs such as `AwsMessageTransportOptions.AutoCreateDestinations = false` for a fully locked-down broker. -Received messages settle with two verbs — the same for queue and pub/sub: +## Delivery settlement + +Received messages surface as `IMessageContext` / `IMessageContext` (id, body, headers, correlation id, priority, `Attempts`) and settle with two verbs: ```csharp -await message.CompleteAsync(); // handled successfully -await message.RejectAsync(); // retry, transport-timed redelivery -await message.RejectAsync(new RejectOptions { RedeliveryDelay = TimeSpan.FromSeconds(30) }); // retry after a delay -await message.RejectAsync(new RejectOptions { Terminal = true, Reason = "validation" }); // do not retry -await message.RenewLockAsync(); +await context.CompleteAsync(); // handled successfully +await context.RejectAsync(); // retry (redelivery) +await context.RejectAsync(new RejectOptions { RedeliveryDelay = TimeSpan.FromSeconds(30) }); +await context.RejectAsync(new RejectOptions { Terminal = true, Reason = "validation", Exception = ex }); +await context.RenewLockAsync(); // long handler heartbeat ``` -`RejectAsync` replaces the separate abandon and dead-letter verbs. A non-terminal reject returns the message for redelivery (optionally after `RedeliveryDelay`); `Terminal = true` means "never redeliver" and routes the message to the dead-letter sink, falling back to a configured destination or a drop (see below). - -Auto-ack is the default: a handler that returns without settling is completed automatically, and a handler that throws is rejected according to the [retry policy](#retry-and-dead-lettering). Manual ack is opt-in with `AckMode.Manual` on the consumer options. +A non-terminal reject returns the message for redelivery (optionally after `RedeliveryDelay`); `Terminal = true` means "never redeliver" and routes the message to the dead-letter sink with the `Reason` and `Exception` forensics attached. `RejectOptions.BestEffortDelay` lets a delay the transport cannot honor degrade to immediate redelivery instead of failing (the core's own retry policy uses best-effort delays; an explicit caller delay defaults to strict). -Unsupported capabilities fail clearly with `NotSupportedException` or a validation exception — there are no silent no-ops for lock renewal, priority, expiration, or delayed delivery. Terminal reject is the one deliberate exception: a transport with no dead-letter sink does not throw, it drops the message (at-most-once for terminal messages), which is the honest behavior for an ack-less/broadcast transport. +Auto-ack is the default: a handler that returns without settling is completed, and a handler that throws is rejected per the retry policy. Manual settlement is opt-in with `AckMode.Manual`. ## Retry and dead-lettering -The core owns retry and dead-lettering, so behavior is identical on every transport (see [The core owns behavior](#the-core-owns-behavior-transports-stay-simple)). A transport only has to redeliver an abandoned message and, optionally, expose a dead-letter sink; the core decides how many times to retry, how long to wait between attempts, and when to give up. The broker's own delivery count is used as a crash-safe attempt counter, so the core owns the *policy* without owning durable retry *state*. +The core owns retry and dead-lettering, so behavior is identical on every transport.

Configure the default and override per subscription: ```csharp services.AddFoundatio() - .Messaging.ConfigureRetry(r => r with { + .Messaging.ConfigureRetry(p => p with + { MaxAttempts = 5, Backoff = attempt => TimeSpan.FromSeconds(Math.Min(30, Math.Pow(2, attempt))), - DeadLetterDestination = "orders-dead-letter" + DeadLetterWhen = ex => ex is ValidationException, // unrecoverable: dead-letter immediately + DeadLetterDestination = "orders-dead-letter" // null derives "{source}.deadletter" }); - -await queue.StartConsumerAsync(HandleAsync, new QueueConsumerOptions { - MaxAttempts = 10 // per-consumer override; null inherits the default policy -}); ``` -When a handler throws, the message is retried (abandoned for redelivery, with the configured backoff) until `MaxAttempts` is reached, then dead-lettered. Where a dead-lettered message lands, in order of preference: - -1. the transport's native dead-letter sink, when it has one (`ISupportsDeadLetter`) — preserving native DLQ tooling; -2. otherwise the configured `RetryPolicy.DeadLetterDestination`, which the core writes to directly (a normal queue on the same transport), recording the reason in the `message.dead_letter.reason` header; -3. otherwise the message is dropped (at-most-once) — the honest outcome when there is nowhere durable to park it. +Deserialization failures are always treated as unrecoverable. Where a dead-lettered message lands, in order of preference: the transport's native dead-letter sink (`ISupportsDeadLetter`), otherwise the configured or derived (`"{source}.deadletter"`) dead-letter destination written by the core. Dead-lettered messages carry forensics headers — `message.dead_letter.reason`, `.attempts`, `.exception_type`, `.exception_message`, `.exception_stack`, `.failed_at`, and `.original_destination` (`KnownHeaders.DeadLetter*`) — so a dead message is triageable with plain transport tooling, and `ISupportsDeadLetter.ReceiveDeadLetteredAsync` reads raw entries back (including poison payloads that never deserialized). -We deliberately do **not** configure broker-native redrive policies (SQS `maxReceiveCount`, Azure Service Bus `MaxDeliveryCount`, RabbitMQ DLX). That would split authority between the broker and the core and make behavior transport-specific. The core is always authoritative; transports stay simple.

A delay longer than the broker can honor — for example beyond SQS's 15-minute delivery delay or 12-hour visibility window — is routed through the durable job runtime store instead of being silently truncated. If neither native support nor a runtime store is available, the operation fails loudly rather than dropping the delay. +A send delay or redelivery backoff is served natively when the transport supports it within its advertised ceiling (`TransportCapabilities.MaxDeliveryDelay`, `ISupportsRedeliveryDelay.MaxRedeliveryDelay`). A delay the broker cannot honor — beyond SQS's 15-minute delivery delay, or any delayed publish on SNS — is parked in the durable runtime store instead of being silently truncated: `MessageBusOptions.RuntimeStore` takes an `IScheduledDispatchStore` (any `IJobRuntimeStore` satisfies it; the DI builder wires it automatically when a runtime store is configured), and the job runtime pump dispatches parked messages when due. If neither native support nor a store is available, the operation fails loudly rather than dropping the delay. ### Unmatched message types -A message that arrives on a destination but whose type has no registered consumer on this node — for example a newer message type during a rolling deploy, before every node has been updated — is surfaced loudly rather than quietly swallowed. It increments the `foundatio.messaging.unhandled` metric and throws `UnhandledMessageTypeException`, isolated to that one message so the receive loop and the other type handlers keep running. The message is retried so a node that *does* handle the type can pick it up, and is finally dead-lettered as `"no-handler"` once `RetryPolicy.UnmatchedMaxAttempts` (default 50) is exhausted — so a genuinely orphaned type cannot loop forever. +A message arriving on a shared destination whose type has no registered consumer on this node — a newer message type mid rolling-deploy, or a misconfiguration — is surfaced loudly: it increments the `foundatio.messaging.unhandled` metric and throws `UnhandledMessageTypeException`, isolated to that one message so the receive loop and the other type handlers keep running. It is retried so a node that *does* handle the type can pick it up, and finally dead-lettered as `"no-handler"` after `RetryPolicy.UnmatchedMaxAttempts` (default 50) — a genuinely orphaned type cannot loop forever. ## Jobs -`IJobClient` submits durable work and returns a `JobHandle`; it does not execute jobs synchronously: +`IJobClient` submits durable work and returns a `JobHandle`; `IJobWorker` claims and executes; `IJobMonitor` queries state; `IJobRuntimeStore` persists all of it. Jobs implement `IJob`: ```csharp -JobHandle handle = await jobs.EnqueueAsync(); +public class RebuildSearchIndexJob : IJob +{ + public async Task RunAsync(JobExecutionContext context) + { + var args = context.GetArguments(); + await context.ReportProgressAsync(50, "halfway"); + return JobResult.Success; + } +} + +JobHandle handle = await jobs.EnqueueAsync(new RebuildSearchIndexArgs { Index = "orders" }); JobState? state = await handle.GetStateAsync(); +await handle.RequestCancellationAsync(); ``` -Execution belongs to `IJobWorker`, which claims queued jobs from `IJobRuntimeStore`. State and operational queries belong to `IJobMonitor`. Scheduled occurrences are created by `IJobScheduler` and materialized by `JobScheduleProcessor` through the runtime store. +**Typed payloads.** `EnqueueAsync(args)` serializes the arguments into the durable `JobState.Payload` (with `PayloadType` stored as a discriminator for forensics); the job reads them via `JobExecutionContext.GetArguments()`, guarded by `HasArguments`. Mismatches throw a descriptive exception naming the stored type. + +**Execution context.** `JobExecutionContext` carries `JobId`, `Attempt`, and the `CancellationToken`, plus the store-backed helpers useful inside job code: `ReportProgressAsync`, `RenewLeaseAsync` (heartbeat for long runs), and `IsCancellationRequestedAsync` (cooperative cancellation). Its public constructor creates a *detached* context for tests — helpers no-op, and an `arguments` object surfaces through `GetArguments` without serialization. + +**The worker.** Every run gets its own async DI scope (scoped services resolve per run, not as accidental singletons). `JobWorker` runs a bounded pool — at most `maxConcurrency` jobs in flight, a slot freeing the moment a job settles — and claims are compare-and-set guarded so concurrency cannot double-run. Lease renewal is a supervised loop, not a fire-and-forget timer: a run is cancelled when its lease is lost to another node *or* when renewal keeps failing past the lease window (the lease has lapsed on the broker's clock too, so continuing would risk double-executing side effects); the terminal state transition is ownership-guarded so a stale worker cannot overwrite the new owner's state. Stale `Processing` jobs (a worker crash mid-run) are reclaimed and re-queued while attempts remain, then dead-lettered. -Persisted job type names come from `IJobTypeRegistry`. Register stable names for jobs that may move between assemblies or namespaces: +### CRON scheduling ```csharp services.AddFoundatio() - .Jobs.Register("search.rebuild") - .Jobs.UseInMemoryRuntime(); + .Jobs.UseInMemoryRuntime() + .Jobs.AddCronJob("0 2 * * *", o => + { + o.MaxRetries = 3; + o.Arguments = new ExportArgs { Format = "csv" }; + }); ``` -Unregistered jobs fall back to `Type.FullName`, not `AssemblyQualifiedName`. - -### Execution context - -A job that wants its runtime identity and store-backed operations implements `IJobWithExecutionContext`; the runtime sets `ExecutionContext` before invoking it. The context exposes `JobId`, `Attempt`, the cancellation token, and `ReportProgressAsync`, `RenewLeaseAsync` (heartbeat for long runs), and `IsCancellationRequestedAsync` — the parts of `IJobRuntimeStore` useful from inside job code. Jobs that use it should be registered transient (the context is per-run state). Untracked queue/pub-sub messages have no progress concept, so `IReceivedMessage` has no `ReportProgressAsync`. - -### Recovery +`AddCronJob(cron, o => ...)` registers a `ScheduledJobDefinition`; `CronJobOptions` covers `Name`, `Scope` (`Global` = one instance per tick, `PerNode` = every instance), `Overlap` (`SkipIfRunning` default), `MisfireWindow`, `MaxRetries`, `TimeZone`, `Enabled`, and typed `Arguments` serialized into every occurrence's payload. Definitions are scheduled automatically when the pump starts — no manual `IJobScheduler.ScheduleAsync` call. The scheduler materializes every occurrence due within the misfire window (not just the latest) as durable, deduplicated store entries, and owns occurrence recovery with its own per-definition retry/dead-letter budget. -The runtime pump reclaims jobs stuck in `Processing` past their lease (a worker that crashed mid-run), not just CRON occurrences: `IJobRuntimeStore.GetExpiredProcessingAsync` surfaces them and the worker re-queues them while attempts remain (`JobRuntimeServiceOptions.MaxJobAttempts`), otherwise dead-letters them. The status CAS serializes concurrent reclaimers. +### The runtime pump -### CRON +`JobRuntimePumpService` is registered automatically with any runtime store, so a configured store can never silently accumulate work that nothing drains. Each poll it materializes CRON occurrences, then runs an **overlapped execution pass** — dispatching due work (message dispatches before job occurrences, so the messaging delayed-delivery fallback is never head-of-line blocked by a long job), recovering stale jobs, and running queued jobs. Scheduling keeps its cadence even while a long pass runs. Tune with `ConfigureRuntimePump`: `JobRuntimePumpOptions.Enabled` (false = manual control), `PollInterval` (1s), `BatchSize` (100), `MaxJobAttempts` (3), and `WorkerConcurrency` (1; every in-flight job still gets its own DI scope, lease, and cancellation watcher). -The redesigned durable CRON path materializes durable, recoverable occurrences through `IJobScheduler` → `JobScheduleProcessor` → the runtime store and pump. The legacy hosted `AddCronJob`/`AddJobScheduler` API still wires the in-process `ScheduledJobService` and is retained as **legacy/compat only**; routing the default hosted CRON API onto the durable scheduler is a planned follow-up (best validated alongside a real provider, since durable distributed CRON leans on the runtime store's transition semantics). +## Testing -## Migration - -Legacy queue code usually moves from one queue instance per payload type to one app-facing queue plus routing: +`Foundatio.Testing` runs the real bus over a recording in-memory transport for deterministic, sleep-free tests: ```csharp -// Legacy -await queue.EnqueueAsync(new OrderSubmitted(id)); // IQueue - -// New -await queue.EnqueueAsync(new OrderSubmitted(id)); // Foundatio.Messaging.IQueue -``` - -Legacy `IMessageBus` publish/subscribe code maps to `IPubSub` with explicit subscription identity: - -```csharp -// Legacy -await messageBus.PublishAsync(new OrderSubmitted(id)); -await messageBus.SubscribeAsync(HandleAsync); +services.AddFoundatio() + .Messaging.UseTestHarness() + .Messaging.AddHandler(); -// New -await pubsub.PublishAsync(new OrderSubmitted(id)); -await using var subscription = await pubsub.SubscribeAsync(HandleAsync); +// start hosted services, then: +await bus.PublishAsync(new OrderPlaced(42)); +await harness.WaitForIdleAsync(); +Assert.Single(harness.Published()); +Assert.Empty(harness.DeadLetteredMessages); ``` -For per-type routing, register each type. For grouped routing, map an interface or base type. For default/global-style routing, set one default queue destination or topic for otherwise unmapped messages. Operation-level overrides should be reserved for exceptional paths such as replays or priority lanes. - -### `IQueue` name collision during migration - -Two public `IQueue` types coexist while the legacy queue is still shipped: - -- `Foundatio.Queues.IQueue` / `IQueue` — the legacy one-type-per-queue API. -- `Foundatio.Messaging.IQueue` — the new app-facing queue. - -A file that has `using` directives for both namespaces will get a `CS0104` ambiguous-reference error on the bare name `IQueue`. Until the legacy API is removed, disambiguate per file with a `using` alias rather than fully qualifying every usage: - -```csharp -using IQueue = Foundatio.Messaging.IQueue; // new code -// or, while finishing a migration: -// using LegacyQueue = Foundatio.Queues.IQueue; -``` +Resolve `MessagingTestHarness` from the container. `WaitForIdleAsync` blocks until every destination has nothing queued and nothing in flight (throws a `TimeoutException` naming the still-busy destinations). Recordings cover every movement — `SentMessages`, `PublishedMessages`, `HandledMessages`, `AbandonedMessages`, `DeadLetteredMessages`, with typed accessors `Sent()` / `Published()` / `Handled()` / `Abandoned()` / `DeadLettered()` — so the core retry/dead-letter path is directly assertable: a message redelivered N times and then dead-lettered shows up as N abandonments plus one dead-letter. -New application code should depend on `Foundatio.Messaging.IQueue`; the alias keeps call sites clean without dropping the legacy namespace a file may still need mid-migration. +## Providers -## Rollout Notes +- **In-memory** (`InMemoryMessageTransport`, `InMemoryJobRuntimeStore`) — the reference implementation for local dev and tests; supports every operation interface. +- **Redis** (`Foundatio.Redis`) — `RedisStreamsMessageTransport` (FIFO streams; delays route through the runtime store) and `RedisJobRuntimeStore`, wired via `.Messaging.UseRedis()` / `.Jobs.UseRedis()` over one shared connection. +- **AWS** (`Foundatio.Aws`) — `AwsMessageTransport` (queues on SQS, pub/sub on SNS+SQS) via `.Messaging.UseAws()`; role-aware capabilities as above, `AutoCreateDestinations` to control implicit resource creation, and LocalStack support via `ServiceUrl`. -The in-memory transport proves the API shape and conformance coverage for local development. Before locking this as a stable public API, validate at least one external provider against the same routing, topic/subscription, delayed delivery, dead-letter, TTL, priority, and batch constraints. +A new provider is validated against the shared conformance suites in `Foundatio.TestHarness`: `MessageTransportConformanceTests` (send/receive, settlement, redelivery, dead-letter, visibility, provisioning — tests skip per unimplemented operation interface) and `JobRuntimeStoreConformanceTests` (state round-trips, CAS transitions, leases, stale recovery including the renew-during-reclaim race, and scheduled-dispatch claiming, driven by a fake time provider).

Smith" Date: Sun, 12 Jul 2026 16:09:38 -0500 Subject: [PATCH 58/94] IScheduledJobManager: runtime CRON management with durable manual triggers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Scheduled jobs could only be managed by whole-definition upserts on IJobScheduler, and there was no way to run one on demand at all — the exact gap the original design review called out (manual run with no idempotency, return value, or completion signal). IScheduledJobManager (DI-registered with the runtime) is the operator surface: list/inspect schedules, add or replace definitions at runtime, RescheduleAsync to change just the cron expression (validated), SetEnabledAsync to pause/resume occurrence materialization, and TriggerAsync to run an immediate occurrence independent of the schedule. A trigger is durable: it materializes a manual occurrence (unique "{name}:manual:…" id, never deduplicated against cron ticks or other manual runs) that the pump claims and executes with the definition's Arguments and retry/dead-letter budget, and returns a JobHandle for state watching and cancellation. Triggering a disabled schedule is refused up front — the run path would otherwise park its dispatch forever. Declaratively-registered CRON jobs share the scheduler store, so they are manageable through the same interface.

Smith" Date: Sun, 12 Jul 2026 16:43:55 -0500 Subject: [PATCH 60/94] Remove the legacy implementations; keep one thin opt-in migration adapter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Keeping the old and new APIs side by side was the confusing part of the branch, so the legacy layer is gone: the old in-memory message bus and its base classes and options, the entire IQueue/Foundatio.Queues subsystem, the old jobs model (JobBase, QueueJobBase, JobWithLockBase, JobRunner, the WorkItemJob system), the hosted legacy job infrastructure (HostedJobService, ScheduledJobService, JobManager, AddJob/AddDistributedCronJob), and all their configuration surface and tests — 60+ files, ~7k lines. What remains for migration is deliberately implementation-free: the old IMessageBus/IMessagePublisher/IMessageSubscriber interface definitions plus LegacyMessageBusAdapter, registered via Messaging.AddLegacyAdapter(), which maps old-style publish/subscribe onto the new bus (per-instance published-only subscriptions matching the old fan-out; DeliveryDelay becomes a durable delayed publish; UniqueId is ignored; the raw IMessage tap has no mapping — the new bus is destination-scoped). Old jobs migrate mechanically and the guide now carries the full old→new mapping table. HybridCacheClient, HybridAwareCacheClient, and CacheLockProvider — the two core features that still rode the legacy bus — now use the new IMessageBus directly with per-instance, published-only subscriptions, so cache invalidation and lock-release notifications get core-owned retry/dead-letter and a durable transport for free. Messaging.UseInMemory() is now the clean all-defaults in-memory setup with no legacy registrations attached.

Smith" Date: Mon, 13 Jul 2026 00:56:40 -0500 Subject: [PATCH 61/94] DX: fail loudly on misconfiguration; surface silent drops; JobResult immutable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The most expensive misconfigurations booted cleanly and did nothing: CRON jobs registered without a runtime store never fired, handlers registered without a transport never attached, an invalid cron expression cost one scrolled-past ERROR at pump start, and duplicate schedule names silently last-won. A startup validation hosted service now fails boot with the exact missing call, cron expressions and duplicate names fail at AddCronJob registration, and startup topology (Ensure/Validate) runs as its own hosted service so publish-only apps in Validate mode fail at boot rather than on first publish. The most common beginner mistake — publishing with no subscriber — produced silence plus a green sent counter. The in-memory transport now warns once per topic when a publish is dropped for having no subscriptions, the core logs a debug line per send with the resolved destination (the produce-side twin of LogSubscription), and PublishAsync documents its drop semantics vs SendAsync's durable queue. JobResult is now an immutable sealed record: the shared Success/Cancelled statics were mutable class instances a single property write could corrupt process-wide, and the byte-identical None duplicate of Success is gone. GetArguments() treats the stored payload discriminator as a guard instead of forensics — deserializing type A's payload as a structurally similar type B silently succeeds with wrong data, so a mismatch now throws before deserialization. A transport that does not advertise ITransportInfo is now assumed queue-only rather than all-roles (an unadvertised role is unsupported, per the capability philosophy) and sends enforce role support. Receive-loop outages log ERROR once then de-escalate to WARN with a running count (recovery logs INFO) instead of an ERROR-per-second firehose, the shared-Key conflict message names the delegate-identity rule, and RenewLeaseAsync documents that renewal is automatic.

Smith" Date: Mon, 13 Jul 2026 01:14:14 -0500 Subject: [PATCH 62/94] =?UTF-8?q?DX:=20consistent=20API=20surface=20?= =?UTF-8?q?=E2=80=94=20ids,=20names,=20exceptions,=20options;=20address-ke?= =?UTF-8?q?yed=20capabilities?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Return types now follow one model: SendAsync, PublishAsync, and every batch verb return the message id(s) — batch ids in input order, transport-reported broker ids replacing the pre-assigned ones. The attempts-vs-retries off-by-one is gone: ScheduledJobDefinition/CronJobOptions.MaxRetries (retries AFTER the first run) became MaxAttempts with the same TOTAL semantics as RetryPolicy and the pump, so "3" now means three runs everywhere. Builder taxonomy is coherent (Use* = pick implementation, Add* = append a registration, Configure* = tune): Jobs.UseInMemoryRuntime → Jobs.UseInMemory (mirroring messaging), RegisterMessageType → AddMessageType, Jobs.Register → AddJobType. IJobScheduler was renamed IScheduledJobStore (with InMemoryScheduledJobStore) — it is the schedule-definition storage contract; IScheduledJobManager remains the management API layered on it, and the two no longer read as overlapping peers. Jobs gained an exception taxonomy (JobException : InvalidOperationException, ScheduledJobNotFoundException, ScheduledJobDisabledException) so TriggerAsync callers can branch on the condition instead of parsing message text. JobWorkerOptions / JobScheduleProcessorOptions tame the nine-positional-optional-parameter constructors; JobStatePatch and the store CAS members are documented as the store-author SPI with relational implementation hints (single atomic conditional statements, SKIP LOCKED for claim-due). ITransportInfo.GetCapabilities is now keyed by DestinationAddress instead of DestinationRole: most transports still answer by role, but the full address is the key so a future routing/composite transport (mixed local + broker destinations) can answer per destination without breaking every provider — the one contract found during the Wolverine review where today's signature would have foreclosed a likely tomorrow. Batch sends validate capabilities per resolved destination group accordingly.

Smith" Date: Mon, 13 Jul 2026 01:28:07 -0500 Subject: [PATCH 63/94] DX: first-class test harnesses for both modules; transport contract documented MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The messaging harness gains await-until primitives — WaitForHandledAsync and WaitForDeadLetteredAsync — so a test waits for the one outcome it cares about instead of draining the whole bus, with timeout messages that report everything that WAS recorded plus DestinationsWithNoConsumer, the diagnostic that names the newcomer's first failing test ("sent, never consumed"). The harness docs now state its clock model honestly: waits are real-time, delayed redeliveries ride the injected TimeProvider, zero backoff is the sleep-free retry pattern — with example tests for both that and FakeTimeProvider advancement. Jobs get their own harness: Jobs.UseTestHarness() wires the in-memory runtime with the auto pump disabled and exposes RunAllQueuedAsync / RunDueAsync(now) / RunToCompletionAsync for deterministic, pump-free job tests — previously a full cycle meant hand-wiring five runtime types. For provider authors, the transport contract is now implementable from its own docs: IMessageTransport/Receive/Subscribe/Receipt/TransportEntry carry the settle semantics (throw-on-failure sends, refuse unhonorable DeliverAt, DeliveryCount increments on abandon, ReceiptExpiredException, receipts as self-contained settlement tokens, optional-init-only contract growth) that previously lived only in the in-memory implementation's comments. The conformance suite adds per-message id, text content-type round-trip, and DLQ consumed-on-read facts.

The existing MessagingSample now also demonstrates EnqueueAsync, the feature the guide leads with but no sample showed. The redesign guide and skill are updated for the whole DX pass: id-returning verbs, boot-time misconfiguration validation, publish drop semantics, immutable JobResult, discriminator-enforced GetArguments, address-keyed capabilities, MaxAttempts, the builder renames, the jobs exception types, both test harnesses, and the documented transport contract.

The caller's verb decides delivery -- `SendAsync` is a command processed by exactly one handler instance across the fleet (competing consumers); `PublishAsync` is an event received once per subscribing service (a scaled service's instances compete), or by every instance when the subscription sets `PerInstance`. Every verb returns the accepted message id(s): `SendAsync`/`PublishAsync` return the message id and `SendBatchAsync` / `PublishBatchAsync` return `IReadOnlyList` in input order. Per-operation options: `MessageSendOptions` / `MessagePublishOptions` (priority, `Delay`/`DeliverAt`, TTL, correlation id, headers, `Destination`/`Topic` override). +- Publish has real pub/sub DROP semantics: a publish to a topic with no existing subscriptions is dropped (subscriptions are created when handlers subscribe or via topology provisioning -- subscribers must exist before the publish). A sent command waits durably on its queue instead. The in-memory transport warns once per topic on zero-subscription drops, and the core logs every produce at debug. - Handlers are topology-free. Implement `IMessageHandler` and register with `.Messaging.AddHandler(o => ...)`; a hosted service (`MessageHandlerHostedService`) starts them all and each message is dispatched in its own DI scope. `IMessageBus.SubscribeAsync` is the dynamic path and returns an `IMessageSubscription` handle. - `MessageSubscriptionOptions` declares delivery intent: `Deliveries` (`MessageDeliveries.Sent`/`Published`/`Both`, default `Both`), `Subscription` / `SubscriptionQualifier` / `PerInstance` for subscriber-group identity, `MaxConcurrency` (default 1, preserves per-handler ordering), `MaxAttempts` / `RedeliveryBackoff` / `DeadLetterWhen` (+ `DeadLetterOn()` shorthand) retry overrides, `AckMode` (`Auto` default / `Manual`), and `Key` (subscriptions sharing a key form one competing group; their backoff/dead-letter DELEGATES are compared by identity, so share delegate instances). - Routing is central: `.Messaging.ConfigureRouting(r => r.UseDefaultQueue(...).UseDefaultTopic(...).MapQueue(...).MapTopic(...).UseServiceIdentity(...).UseSubscriptionIdentity(...).UseConvention(...))`. Precedence: operation override > exact map > interface/base-type map > `MessageRouteAttribute` > configured default > convention > kebab-cased type name. -- Routing config doubles as topology declarations (`DestinationDeclaration` with a canonical `DestinationAddress` -- `ForQueue`/`ForTopic`/`ForSubscription`). `IMessageTopology` exposes `GetDeclarations()` / `EnsureAsync()` / `ValidateAsync()`. `.Messaging.ConfigureTopology(TopologyMode.Ensure | Validate | None)` picks whether the client creates missing destinations (default), only verifies they exist (throws at startup when missing), or never touches topology; the handler host applies the mode at startup. +- Routing config doubles as topology declarations (`DestinationDeclaration` with a canonical `DestinationAddress` -- `ForQueue`/`ForTopic`/`ForSubscription`). `IMessageTopology` exposes `GetDeclarations()` / `EnsureAsync()` / `ValidateAsync()`. `.Messaging.ConfigureTopology(TopologyMode.Ensure | Validate | None)` picks whether the client creates missing destinations (default), only verifies they exist (throws at startup when missing), or never touches topology; startup topology (Ensure/Validate) runs as its own hosted service for EVERY app with a transport -- publish-only apps included. - The CORE owns retry/dead-lettering identically on every transport: default `RetryPolicy` is `MaxAttempts` 5 with immediate-then-10s/20s/30s backoff (+/-20% jitter); configure via `.Messaging.ConfigureRetry(p => p with { ... })`. Dead-lettered messages go to the transport's native sink or a derived `"{source}.deadletter"` destination, stamped with `message.dead_letter.*` forensics headers (`KnownHeaders.DeadLetter*`). Never configure broker-native redrive policies. - Message settlement: `IMessageContext` / `IMessageContext` with `CompleteAsync()`, `RejectAsync(RejectOptions)` (non-terminal = retry, optionally with `RedeliveryDelay`; `Terminal = true` = dead-letter with `Reason`/`Exception`), and `RenewLockAsync()`. Auto-ack is the default. -- Transports advertise role-aware capabilities: `ITransportInfo.GetCapabilities(DestinationRole)` returns `TransportCapabilities` (e.g. the AWS transport's queue role has a native 15-minute `MaxDeliveryDelay`; its topic role has none). Delays beyond a ceiling and store-parked retries fall back to the durable runtime store (`IScheduledDispatchStore`, satisfied by any `IJobRuntimeStore`) and are drained by the job runtime pump -- never silently truncated. -- Durable jobs: implement `IJob` (`Task RunAsync(JobExecutionContext context)`). `IJobClient.EnqueueAsync()` / `EnqueueAsync(args)` (typed payloads) returns a `JobHandle`; `IJobMonitor` queries state; `IJobWorker` executes with per-run DI scopes, bounded concurrency, and supervised lease renewal. `JobExecutionContext` gives `JobId`/`Attempt`/`CancellationToken`, `GetArguments()`, `ReportProgressAsync`, `RenewLeaseAsync`, `IsCancellationRequestedAsync`; its public constructor makes a detached context for tests. -- CRON: `.Jobs.AddCronJob("0 */6 * * *", o => ...)` with `CronJobOptions` (`Scope` Global/PerNode, `Overlap`, `MisfireWindow`, `MaxRetries`, `TimeZone`, typed `Arguments`).

Tune the pump with `.Jobs.ConfigureRuntimePump(o => ...)` (`JobRuntimePumpOptions`: `Enabled`, `PollInterval`, `BatchSize`, `MaxJobAttempts`, `WorkerConcurrency`). +- Transports advertise per-destination capabilities: `ITransportInfo.GetCapabilities(destination)` takes the `DestinationAddress` in question (most transports answer by its role) and returns `TransportCapabilities` (e.g. the AWS transport's queue role has a native 15-minute `MaxDeliveryDelay`; its topic role has none). Delays beyond a ceiling and store-parked retries fall back to the durable runtime store (`IScheduledDispatchStore`, satisfied by any `IJobRuntimeStore`) and are drained by the job runtime pump -- never silently truncated. +- Durable jobs: implement `IJob` (`Task RunAsync(JobExecutionContext context)`). `JobResult` is an immutable record -- return the shared `JobResult.Success`/`JobResult.Cancelled` statics or the `SuccessWithMessage`/`FailedWithMessage`/`CancelledWithMessage`/`FromException` factories (there is no `None`). `IJobClient.EnqueueAsync()` / `EnqueueAsync(args)` (typed payloads) returns a `JobHandle`; `IJobMonitor` queries state; `IJobWorker` executes with per-run DI scopes, bounded concurrency, and supervised lease renewal. `JobExecutionContext` gives `JobId`/`Attempt`/`CancellationToken`, `GetArguments()`, `ReportProgressAsync`, `RenewLeaseAsync`, `IsCancellationRequestedAsync`; its public constructor makes a detached context for tests. `GetArguments` enforces the stored payload-type discriminator: requesting a different type than the job was enqueued with throws before deserialization.

All provider docs (Redis, Az ## Messaging and Jobs (current API) -- One messaging client: `IMessageBus` in `Foundatio.Messaging`. The caller's verb decides delivery -- `SendAsync` is a command processed by exactly one handler instance across the fleet (competing consumers); `PublishAsync` is an event received once per subscribing service (a scaled service's instances compete), or by every instance when the subscription sets `PerInstance`. Every verb returns the accepted message id(s): `SendAsync`/`PublishAsync` return the message id and `SendBatchAsync` / `PublishBatchAsync` return `IReadOnlyList` in input order. Per-operation options: `MessageSendOptions` / `MessagePublishOptions` (priority, `Delay`/`DeliverAt`, TTL, correlation id, headers, `Destination`/`Topic` override). +- One messaging client: `IMessageBus` in `Foundatio.Messaging`. `SendAsync` targets competing queue consumers; `PublishAsync` fans out to existing event subscriptions. Delivery is at least once where supported, so handlers must tolerate duplicates. Both return application IDs, independently of broker IDs. Supply `MessageSendOptions.MessageId` / `MessagePublishOptions.MessageId` for retry correlation; this does not create exactly-once delivery. Batches return IDs in input order; `MessageSendException.Outcomes` distinguishes accepted, unknown, and unattempted inputs on failure. - Publish has real pub/sub DROP semantics: a publish to a topic with no existing subscriptions is dropped (subscriptions are created when handlers subscribe or via topology provisioning -- subscribers must exist before the publish). A sent command waits durably on its queue instead. The in-memory transport warns once per topic on zero-subscription drops, and the core logs every produce at debug. -- Handlers are topology-free. Implement `IMessageHandler` and register with `.Messaging.AddHandler(o => ...)`; a hosted service (`MessageHandlerHostedService`) starts them all and each message is dispatched in its own DI scope. `IMessageBus.SubscribeAsync` is the dynamic path and returns an `IMessageSubscription` handle. -- `MessageSubscriptionOptions` declares delivery intent: `Deliveries` (`MessageDeliveries.Sent`/`Published`/`Both`, default `Both`), `Subscription` / `SubscriptionQualifier` / `PerInstance` for subscriber-group identity, `MaxConcurrency` (default 1, preserves per-handler ordering), `MaxAttempts` / `RedeliveryBackoff` / `DeadLetterWhen` (+ `DeadLetterOn()` shorthand) retry overrides, `AckMode` (`Auto` default / `Manual`), and `Key` (subscriptions sharing a key form one competing group; their backoff/dead-letter DELEGATES are compared by identity, so share delegate instances). -- Routing is central: `.Messaging.ConfigureRouting(r => r.UseDefaultQueue(...).UseDefaultTopic(...).MapQueue(...).MapTopic(...).UseServiceIdentity(...).UseSubscriptionIdentity(...).UseConvention(...))`. Precedence: operation override > exact map > interface/base-type map > `MessageRouteAttribute` > configured default > convention > kebab-cased type name. -- Routing config doubles as topology declarations (`DestinationDeclaration` with a canonical `DestinationAddress` -- `ForQueue`/`ForTopic`/`ForSubscription`). `IMessageTopology` exposes `GetDeclarations()` / `EnsureAsync()` / `ValidateAsync()`. `.Messaging.ConfigureTopology(TopologyMode.Ensure | Validate | None)` picks whether the client creates missing destinations (default), only verifies they exist (throws at startup when missing), or never touches topology; startup topology (Ensure/Validate) runs as its own hosted service for EVERY app with a transport -- publish-only apps included. +- Implement `IMessageHandler` and explicitly register `.Messaging.AddConsumer()` for queued work or `.Messaging.AddSubscriber("billing")` for events. Each message uses its own DI scope. Dynamic equivalents are `ConsumeAsync` and `SubscribeAsync`, returning an `IMessageSubscription` with its structural `Source` address. +- `MessageConsumerOptions` sets an optional queue destination. `MessageSubscriptionOptions` sets an optional topic and explicit durable subscription name: replicas using the same name compete. In dynamic SubscribeAsync, null creates a temporary listener with a renewable expiration lease on in-memory/Redis; AWS requires a durable name. Shared `MessageHandlerOptions` controls endpoint concurrency (default 1), retries and acknowledgement. Duplicate concrete handlers and multiple interface/raw fallback handlers on one endpoint are rejected. Manual acknowledgement holds its concurrency slot until settlement. +- Routing is central: `.Messaging.ConfigureRouting(r => r.UseDefaultQueue(...).UseDefaultTopic(...).MapQueue(...).MapTopic(...).UseConvention(...))`. Precedence: operation override > exact map > interface/base-type map > `MessageRouteAttribute` > configured default > convention > kebab-cased type name. Producer routing declares queues/topics, never phantom subscriber groups. +- Routing config doubles as topology declarations (`DestinationDeclaration` with a canonical `DestinationAddress` -- `ForQueue`/`ForTopic`/`ForSubscription`). `IMessageTopology` exposes `GetDeclarations()` / `EnsureAsync()` / `ValidateAsync()`. `.Messaging.ConfigureTopology(TopologyMode.Ensure | Validate | None)` picks whether the client creates missing destinations (default), only verifies they exist (throws at startup when missing), or never touches topology; AddMessageConsumers includes startup topology; producers can opt in with AddMessagingTopology. Registering a transport starts no hosted services. - The CORE owns retry/dead-lettering identically on every transport: default `RetryPolicy` is `MaxAttempts` 5 with immediate-then-10s/20s/30s backoff (+/-20% jitter); configure via `.Messaging.ConfigureRetry(p => p with { ... })`. Dead-lettered messages go to the transport's native sink or a derived `"{source}.deadletter"` destination, stamped with `message.dead_letter.*` forensics headers (`KnownHeaders.DeadLetter*`). Never configure broker-native redrive policies. -- Message settlement: `IMessageContext` / `IMessageContext` with `CompleteAsync()`, `RejectAsync(RejectOptions)` (non-terminal = retry, optionally with `RedeliveryDelay`; `Terminal = true` = dead-letter with `Reason`/`Exception`), and `RenewLockAsync()`. Auto-ack is the default. -- Transports advertise per-destination capabilities: `ITransportInfo.GetCapabilities(destination)` takes the `DestinationAddress` in question (most transports answer by its role) and returns `TransportCapabilities` (e.g. the AWS transport's queue role has a native 15-minute `MaxDeliveryDelay`; its topic role has none). Delays beyond a ceiling and store-parked retries fall back to the durable runtime store (`IScheduledDispatchStore`, satisfied by any `IJobRuntimeStore`) and are drained by the job runtime pump -- never silently truncated. +- Settlement succeeds only after the broker operation succeeds. A failed DLQ write leaves the original unsettled. `IMessageContext` exposes application `Id`, diagnostic `BrokerMessageId`, `CompleteAsync`, `RejectAsync`, and cancellation. Expiring delivery leases are supervised and renewed while a handler runs; lease loss cancels the handler and prevents settlement. Direct loops use `await using var message = await bus.ReceiveAsync(options, token)`; disposal returns unfinished work for redelivery. Raw receive requires an explicit destination. +- Transports advertise per-destination capabilities: `ITransportInfo.GetCapabilities(destination)` takes the `DestinationAddress` in question (most transports answer by its role) and returns `TransportCapabilities` (e.g. the AWS transport's queue role has a native 15-minute `MaxDeliveryDelay`; its topic role has none). Delays beyond a ceiling and store-parked retries fall back to the durable runtime store (`IScheduledDispatchStore`, satisfied by any `IJobRuntimeStore`) and are drained by an explicitly hosted ScheduledMessageDispatcher -- never silently truncated. - Durable jobs: implement `IJob` (`Task RunAsync(JobExecutionContext context)`). `JobResult` is an immutable record -- return the shared `JobResult.Success`/`JobResult.Cancelled` statics or the `SuccessWithMessage`/`FailedWithMessage`/`CancelledWithMessage`/`FromException` factories (there is no `None`). `IJobClient.EnqueueAsync()` / `EnqueueAsync(args)` (typed payloads) returns a `JobHandle`; `IJobMonitor` queries state; `IJobWorker` executes with per-run DI scopes, bounded concurrency, and supervised lease renewal. `JobExecutionContext` gives `JobId`/`Attempt`/`CancellationToken`, `GetArguments()`, `ReportProgressAsync`, `RenewLeaseAsync`, `IsCancellationRequestedAsync`; its public constructor makes a detached context for tests. `GetArguments` enforces the stored payload-type discriminator: requesting a different type than the job was enqueued with throws before deserialization. Hand-wiring outside DI: `JobWorker`/`JobScheduleProcessor` take `JobWorkerOptions`/`JobScheduleProcessorOptions` records for their optional dependencies. -- CRON: `.Jobs.AddCronJob("0 */6 * * *", o => ...)` with `CronJobOptions` (`Scope` Global/PerNode, `Overlap`, `MisfireWindow`, `MaxAttempts` -- the TOTAL run attempts per failed occurrence, default 3 -- `TimeZone`, typed `Arguments`). An invalid cron expression or duplicate schedule name throws at the `AddCronJob` call itself. Scheduled automatically when the runtime pump starts. Tune the pump with `.Jobs.ConfigureRuntimePump(o => ...)` (`JobRuntimePumpOptions`: `Enabled`, `PollInterval`, `BatchSize`, `MaxJobAttempts`, `WorkerConcurrency`). -- Startup validation fails fast at boot with actionable messages: CRON jobs registered without a runtime store, or handlers registered without a transport, throw when the host starts (add `.Jobs.UseInMemory()` / `.Messaging.UseInMemory()` or the production `Use*`). +- CRON: `.Jobs.AddCronJob(cron)` or `.Jobs.AddCronJob(cron,args)`; typed jobs implement `IJob`. Schedules persist wire names, serialized payloads, time-zone IDs, retry budgets, and revisions. `ConfigurationVersion` must increase for a changed declaration; same-version restarts preserve runtime edits. `ScheduleAsync` uses revision checks. Global and per-node occurrences share the same job worker/state machine. +- `AddFoundatioWorker` validates missing transports/stores during registration. Receiving options, durable names, concrete job types, and schedule options also fail at registration. With individually hosted roles, startup validation fails fast at boot with actionable messages: CRON jobs registered without a runtime store, or handlers registered without a transport, throw when the corresponding consumer/scheduler host starts (add `.Jobs.UseInMemory()` / `.Messaging.UseInMemory()` or the production `Use*`). - Jobs exceptions on the trigger/resolve paths: `ScheduledJobNotFoundException` (unknown schedule name), `ScheduledJobDisabledException` (triggering a disabled schedule), and `JobException` (unresolvable job type); all derive from `JobException` : `InvalidOperationException`. -- Runtime schedule management: `IScheduledJobManager` (DI-registered with the runtime) lists/inspects schedules, adds or replaces `ScheduledJobDefinition`s on the fly, `RescheduleAsync(name, cron)` changes just the schedule, `SetEnabledAsync(name, bool)` pauses/resumes materialization, and `TriggerAsync(name)` runs an immediate durable occurrence (definition's `Arguments` + retry budget) returning a `JobHandle`. Triggering a disabled schedule throws; manual occurrences never dedupe and bypass `Overlap` accounting. Generic overloads (`GetScheduleAsync()`, `TriggerAsync()`, `RescheduleAsync(cron)`, `SetEnabledAsync(bool)`, `UnscheduleAsync()`) resolve the schedule name via `ScheduledJobDefinition.DefaultNameFor(type)` — the same default `AddCronJob` uses when no explicit name is given. -- Stable wire names: `.Messaging.AddMessageType("name")` and `.Jobs.AddJobType("name")` so persisted discriminators survive assembly/namespace moves; unregistered types fall back to `Type.FullName`. +- Schedule management: `IScheduledJobManager` supports inspect, revision-checked updates, enable/disable, reschedule, remove, and manual trigger. Manual triggers respect disabled/overlap policy. Removing a definition does not cancel already queued jobs. +- Stable wire names: `.Messaging.AddMessageType("order-created.v1")` and `.Jobs.AddJobType("name")` preserve persisted discriminators across refactors. Polymorphic message deserialization resolves only explicitly registered names; it never scans loaded assemblies. Concrete handlers can use the default CLR full name. Producers and consumers must use the same serializer/content type. SystemTextJson defaults to application/json; other serializers default to byte-safe application/octet-stream unless ContentType is explicitly configured. Metadata and application IDs survive scheduling and dead-lettering. - Legacy implementations were removed. For migration, `Messaging.AddLegacyAdapter()` registers the old `IMessageBus`/`IMessagePublisher`/`IMessageSubscriber` interfaces as a thin adapter over the new bus (old handler code compiles unchanged; delete the call when migrated). Old jobs migrate mechanically: `RunAsync(CancellationToken)` becomes `RunAsync(JobExecutionContext)` (use `context.CancellationToken`), `QueueJobBase`/`IQueue` become `IMessageHandler` + `SendAsync`, and `WorkItemJob` becomes `EnqueueAsync(args)` with `ReportProgressAsync`. ## Core Interfaces @@ -56,25 +56,24 @@ Query with specific questions, not single keywords.

Set an explicit shared `Subscription` only when they should compete. -- **Shared subscription keys compare delegates by identity**: subscriptions sharing a `Key` must pass the SAME `RedeliveryBackoff`/`DeadLetterWhen` delegate instances -- a lambda recreated per subscription is rejected as a conflicting registration. +- **Shared Redis connection**: messaging and jobs share one multiplexer. Configure ConnectionStrings:Redis, provide one explicit UseRedis connection string, or register the multiplexer. Conflicting explicit strings fail at registration; omit connectionString when using an existing multiplexer. + +- **Explicit receiving intent**: `AddConsumer` registers queued work; `AddSubscriber(..., "stable-group")` registers a durable event subscription. Replicas in the same group compete. DI AddSubscriber requires a nonblank name; use AddTemporarySubscriber explicitly for temporary listeners. Dynamic unnamed subscriptions require expiring-subscription support (in-memory/Redis); AWS requires a durable name. - **Do not configure broker redrive policies**: the core owns retry/dead-lettering (SQS `maxReceiveCount`, DLX, etc. would split authority and make behavior transport-specific). -- **A runtime store needs its pump**: the DI builder auto-registers `JobRuntimePumpService` with any runtime store, but in a non-hosted process (no generic host) nothing starts it -- drive `JobScheduleProcessor`/`IJobWorker` manually or nothing drains. +- **Hosting is explicit**: AddFoundatioWorker(configure, jobConcurrency: 1) hosts the roles selected by its callback. Plain AddFoundatio client/storage registrations start no services. For split deployments, add `AddMessageConsumers`, `AddJobWorker(concurrency)`, `AddJobScheduler`, and/or `AddScheduledMessageDispatcher` only where each role should run. Workers, schedulers, and dispatchers are independent. `AddMessagingTopology` is available for producer-only startup checks. - **Delayed sends beyond transport ceilings need a runtime store**: e.g. > 15 min on SQS, or any delayed publish on SNS topics. Without a store the operation fails loudly rather than truncating the delay. -- **`WaitForIdleAsync` ignores store-parked work**: delayed sends/retries parked in the runtime store are not transport activity -- drain them via the job schedule processor before asserting. +- **`WaitForIdleAsync` ignores store-parked work**: delayed sends/retries parked in the runtime store are not transport activity -- drain them via ScheduledMessageDispatcher before asserting. - **Lock returns null**: `TryAcquireAsync` returns `null` when the lock cannot be acquired -- always guard with `is not null`. `AcquireAsync` throws `LockAcquisitionTimeoutException` instead of returning null. - **Dispose streams and locks**: `ILock` is `IAsyncDisposable` -- use `await using`. Streams from `GetFileStreamAsync` are `IDisposable` -- use `using var`. - **Cache `GetAsync` returns `CacheValue`**: check `result.HasValue` before `result.Value`. A missing key returns `HasValue = false`, not an exception. - **Cache stampede**: serialize regeneration of hot keys with `CacheLockProvider` (lock on the cache key, double-check after acquiring). See the [Cache Stampede Protection](https://foundatio.readthedocs.io/guide/caching.html#cache-stampede-protection) docs. - **Register as singletons**: infrastructure services (`ICacheClient`, `IMessageBus`, `IFileStorage`, `ILockProvider`) maintain internal state and connections; the `AddFoundatio()` builder does this for you. -- **In-memory for tests**: in-memory implementations are functionally equivalent to production providers and run the same conformance suites -- swap via DI for fast, isolated tests. +- **In-memory for tests**: in-memory implementations run the same applicable conformance suites for fast, isolated tests.

For producer-only APIs and manually driven tests, use `AddFoundatio()` instead. ```csharp using Foundatio; -builder.Services.AddFoundatio(); // Adds default in-memory implementations -``` - -## Service Lifetimes - -### Recommended Lifetimes - -| Service | Lifetime | Reason | -|---------|----------|--------| -| `ICacheClient` | Singleton | Maintains internal state/connection | -| `IMessageBus` | Singleton | Maintains subscriptions | -| `ILockProvider` | Singleton | Stateless, thread-safe | -| `IFileStorage` | Singleton | Stateless, thread-safe | -| `IQueue` | Singleton | Maintains queue state | -| Jobs | Scoped | Per-execution isolation | - -### Example Registration - -```csharp -// Singletons for infrastructure -builder.Services.AddSingleton(sp => - new InMemoryCacheClient(o => o.MaxItems = 1000)); - -builder.Services.AddSingleton(); - -// Scoped for per-request isolation -builder.Services.AddScoped(sp => - new ScopedLockProvider( - sp.GetRequiredService(), - $"tenant:{GetCurrentTenantId(sp)}" - ) -); -``` - -## Environment-Based Configuration - -### Development vs Production - -```csharp -if (builder.Environment.IsDevelopment()) -{ - // In-memory for development - builder.Services.AddSingleton(); - builder.Services.AddSingleton(); - builder.Services.AddSingleton(); -} -else -{ - // Container-owned Redis connection for production - builder.Services.AddSingleton(sp => - ConnectionMultiplexer.Connect( - builder.Configuration.GetConnectionString("Redis") - )); - - builder.Services.AddSingleton(sp => - new RedisCacheClient(o => o.ConnectionMultiplexer = - sp.GetRequiredService())); - - builder.Services.AddSingleton(sp => - new RedisMessageBus(o => o.Subscriber = - sp.GetRequiredService().GetSubscriber())); - - builder.Services.AddSingleton(sp => - new AzureFileStorage(o => { - o.ConnectionString = builder.Configuration["Azure:StorageConnectionString"]; - o.ContainerName = "files"; - })); -} -``` - -### Using Options Pattern - -```csharp -// appsettings.json -{ - "Foundatio": { - "Cache": { - "Type": "Redis", - "MaxItems": 1000 - }, - "Storage": { - "Type": "Azure", - "ContainerName": "files" - } - } -} - -// Registration -builder.Services.Configure( - builder.Configuration.GetSection("Foundatio")); - -builder.Services.AddSingleton(sp => -{ - var options = sp.GetRequiredService>().Value; - return options.Cache.Type switch - { - "Redis" => new RedisCacheClient(...), - "InMemory" => new InMemoryCacheClient(o => o.MaxItems = options.Cache.MaxItems), - _ => throw new InvalidOperationException() - }; -}); +builder.Services.AddFoundatioWorker(foundatio => foundatio + .Caching.UseInMemory() + .Storage.UseInMemory() + .Locking.UseCache() + .Messaging.UseInMemory() + .Messaging.AddConsumer() + .Messaging.AddSubscriber("billing") + .Jobs.UseInMemory() + .Jobs.AddJobType("generate-report.v1")); ``` -## Named/Keyed Services - -### Multiple Implementations - -```csharp -// Multiple caches -builder.Services.AddKeyedSingleton("session", - sp => new InMemoryCacheClient(o => o.MaxItems = 10000)); - -builder.Services.AddKeyedSingleton("data", - sp => new RedisCacheClient(o => o.ConnectionMultiplexer = redis)); - -// Multiple queues -builder.Services.AddKeyedSingleton>("high-priority", - sp => new InMemoryQueue()); +## Choose host roles explicitly -builder.Services.AddKeyedSingleton>("low-priority", - sp => new InMemoryQueue()); -``` +`AddFoundatio()` starts no hosted services. For split deployments, register clients, stores, handlers, and job types with it, then choose only the roles that process runs. These individual methods live in `Foundatio.Extensions.Hosting.Messaging` and `Foundatio.Extensions.Hosting.Jobs`. -### Injecting Keyed Services - -```csharp -public class OrderService -{ - private readonly ICacheClient _sessionCache; - private readonly ICacheClient _dataCache; - - public OrderService( - [FromKeyedServices("session")] ICacheClient sessionCache, - [FromKeyedServices("data")] ICacheClient dataCache) - { - _sessionCache = sessionCache; - _dataCache = dataCache; - } -} -``` - -## Factory Pattern - -### Dynamic Resolution - -```csharp -public interface ICacheClientFactory -{ - ICacheClient GetCache(string name); -} +| Registration | Responsibility | +| --- | --- | +| `AddMessageConsumers()` | Start registered consumers/subscribers and apply startup topology policy | +| `AddMessagingTopology()` | Optional producer-only topology startup checks | +| `AddJobWorker(concurrency)` | Execute registered job types | +| `AddJobScheduler()` | Reconcile declarations and materialize due CRON occurrences | +| `AddScheduledMessageDispatcher()` | Send messages parked in an `IScheduledDispatchStore` | -public class CacheClientFactory : ICacheClientFactory -{ - private readonly IServiceProvider _services; - private readonly ConcurrentDictionary _caches = new(); +`AddFoundatioWorker` selects these roles for a combined worker: consumers when a transport is configured, worker and scheduler when job types are registered, and delayed dispatch when both a transport and dispatch store are configured. Set its `jobConcurrency` argument to control simultaneous job executions; set message concurrency on each receiving endpoint. - public CacheClientFactory(IServiceProvider services) - { - _services = services; - } +Scheduler, worker, and dispatcher loops run independently. A long-running job does not block delayed-message delivery or schedule materialization. Host registrations are idempotent. - public ICacheClient GetCache(string name) - { - return _caches.GetOrAdd(name, n => - { - var baseCache = _services.GetRequiredService(); - return new ScopedCacheClient(baseCache, n); - }); - } -} +## Service lifetimes and ownership -// Registration -builder.Services.AddSingleton(); -builder.Services.AddSingleton(); -``` +Keep infrastructure clients, transport connections, stores, and buses as singletons. Inject interfaces into business services. Handler and job dependencies may be scoped, including database contexts; a fresh scope is created for each invocation and disposed after execution. -## Multi-Tenant Support +The container owns transports registered through the builder. For manual construction, `MessageBus` owns its supplied transport by default. Set `MessageBusOptions.OwnsTransport = false` only when another owner manages that transport. Dispose directly created buses and use `await using` for subscriptions, received deliveries, and locks. -### Tenant-Scoped Services +Avoid capturing a scoped dependency inside a singleton factory or long-lived delegate. Class handlers with constructor injection are the usual choice: ```csharp -public interface ITenantAccessor +public sealed class ProcessOrderHandler(OrderService orders) : IMessageHandler { - string TenantId { get; } + public Task HandleAsync(IMessageContext context, CancellationToken token) + => orders.ProcessAsync(context.Message, token); } - -// Scoped cache per tenant -builder.Services.AddScoped(sp => -{ - var baseCache = sp.GetRequiredService(); - var tenant = sp.GetRequiredService(); - return new ScopedCacheClient(baseCache, $"tenant:{tenant.TenantId}"); -}); - -// Scoped storage per tenant -builder.Services.AddScoped(sp => -{ - var baseStorage = sp.GetRequiredService(); - var tenant = sp.GetRequiredService(); - return new ScopedFileStorage(baseStorage, tenant.TenantId); -}); - -// Scoped locks per tenant -builder.Services.AddScoped(sp => -{ - var baseLock = sp.GetRequiredService(); - var tenant = sp.GetRequiredService(); - return new ScopedLockProvider(baseLock, tenant.TenantId); -}); ``` -## Health Checks +## Providers and testing -### Register Health Checks - -```csharp -builder.Services.AddHealthChecks() - .AddCheck("cache") - .AddCheck("storage") - .AddCheck("queue"); - -public class CacheHealthCheck : IHealthCheck -{ - private readonly ICacheClient _cache; - - public CacheHealthCheck(ICacheClient cache) => _cache = cache; - - public async Task CheckHealthAsync( - HealthCheckContext context, - CancellationToken cancellationToken = default) - { - try - { - await _cache.SetAsync("health-check", DateTime.UtcNow); - var result = await _cache.GetAsync("health-check"); - - return result.HasValue - ? HealthCheckResult.Healthy() - : HealthCheckResult.Unhealthy("Cache read failed"); - } - catch (Exception ex) - { - return HealthCheckResult.Unhealthy(ex.Message); - } - } -} -``` +Swap `.Messaging.UseInMemory()` for a supported production transport, or `.Jobs.UseInMemory()` for a durable store. Check the [provider matrix](messaging.md#provider-guarantees): ordering, temporary subscriptions, native delays, and dead-letter administration are not identical across brokers. -## Testing - -### Test-Friendly Registration - -```csharp -// In test setup -public class TestStartup -{ - public void ConfigureServices(IServiceCollection services) - { - // Always use in-memory for tests - services.AddSingleton(); - services.AddSingleton(); - services.AddSingleton(); - services.AddSingleton(sp => - new CacheLockProvider( - sp.GetRequiredService(), - sp.GetRequiredService() - ) - ); - } -} -``` - -### Isolated Tests - -```csharp -public class OrderServiceTests -{ - private readonly ServiceProvider _services; - - public OrderServiceTests() - { - var services = new ServiceCollection(); - - // Fresh instances for each test class - services.AddSingleton(); - services.AddSingleton(); - - _services = services.BuildServiceProvider(); - } - - [Fact] - public async Task CreateOrder_CachesOrder() - { - var cache = _services.GetRequiredService(); - var service = new OrderService(cache); - - var order = await service.CreateOrderAsync(new CreateOrderRequest()); - - var cached = await cache.GetAsync($"order:{order.Id}"); - Assert.True(cached.HasValue); - } -} -``` - -## Best Practices - -### 1. Proper Resource Disposal - -Foundatio services implement `IDisposable` and/or `IAsyncDisposable`. The DI container handles disposal for registered services, but you must handle disposal correctly for manually created instances. - -```csharp -// ✅ Good: DI container handles disposal -builder.Services.AddSingleton(); -// Container disposes when application shuts down - -// ✅ Good: Using statement for short-lived instances -await using var cache = new InMemoryCacheClient(); -await cache.SetAsync("key", "value"); -// Automatically disposed - -// ✅ Good: Manual disposal when needed -var queue = new InMemoryQueue(); -try -{ - await queue.EnqueueAsync(new WorkItem()); -} -finally -{ - queue.Dispose(); // Or await using for IAsyncDisposable -} - -// ❌ Bad: Not disposing manually created instances -var cache = new InMemoryCacheClient(); -// ... use cache -// Never disposed - resources leak! -``` - -### 2. Async Disposal with `await using` - -For services implementing `IAsyncDisposable`, prefer `await using`: - -```csharp -// Locks implement IAsyncDisposable -await using var lck = await locker.AcquireAsync("resource"); -if (lck is null) - throw new InvalidOperationException("Failed to acquire lock on 'resource'"); - -await DoWork(); -// Lock automatically released - -// Queue entries should be completed/abandoned -var entry = await queue.DequeueAsync(); -if (entry is null) - return; - -try -{ - await ProcessAsync(entry.Value); - await entry.CompleteAsync(); -} -catch -{ - await entry.AbandonAsync(); - throw; -} -``` - -### 3. Use Interfaces for Dependencies - -```csharp -// ✅ Good: Interface dependency -public class OrderService -{ - private readonly ICacheClient _cache; - - public OrderService(ICacheClient cache) - { - _cache = cache; - } -} - -// ❌ Bad: Concrete dependency -public class OrderService -{ - private readonly RedisCacheClient _cache; // Harder to test -} -``` - -### 4. Avoid Service Locator Pattern - -```csharp -// ✅ Good: Constructor injection -public class MyService -{ - private readonly ICacheClient _cache; - - public MyService(ICacheClient cache) - { - _cache = cache; - } -} - -// ❌ Bad: Service locator -public class MyService -{ - private readonly IServiceProvider _services; - - public void DoWork() - { - var cache = _services.GetService(); - } -} -``` - -### 5. Register as Singletons When Appropriate - -```csharp -// Stateless services that maintain connections -builder.Services.AddSingleton(...); -builder.Services.AddSingleton(...); - -// Not scoped unless you need tenant isolation -``` - -### 6. Validate Configuration at Startup - -```csharp -builder.Services.AddSingleton(sp => -{ - var connectionString = builder.Configuration["Redis:ConnectionString"]; - if (string.IsNullOrEmpty(connectionString)) - throw new InvalidOperationException("Redis connection string not configured"); - - var redis = ConnectionMultiplexer.Connect(connectionString); - return new RedisCacheClient(o => o.ConnectionMultiplexer = redis); -}); -``` +Use `.Messaging.UseTestHarness()` and `.Jobs.UseTestHarness()` from `Foundatio.Testing` for tests that exercise the real runtime. Messaging tests explicitly start consumers. Job tests drive the harness worker/scheduler themselves; no background worker races their assertions. Dispose each test's service provider to isolate resources. -## Next Steps +For keyed caches or storage services, standard `AddKeyedSingleton` and `[FromKeyedServices]` remain available. A single message bus routes by queue/topic; use explicit destinations and subscriber names instead of registering a separate typed queue service for every message type. -- [Configuration](./configuration) - Configuration options for Foundatio services -- [Caching](./caching) - Deep dive into caching -- [Getting Started](./getting-started) - Initial setup guide +See [Getting started](getting-started.md), [Messaging](messaging.md), and [Durable jobs](jobs.md) for current setup and migration examples. diff --git a/docs/guide/getting-started.md b/docs/guide/getting-started.md index e2a235504..62390a991 100644 --- a/docs/guide/getting-started.md +++ b/docs/guide/getting-started.md @@ -1,266 +1,65 @@ -# Getting Started +# Getting started -This guide will walk you through installing Foundatio and using your first abstractions. +Foundatio supplies swappable caching, file storage, locking, messaging, and background job building blocks.

Use durable jobs when callers need a handle, progress, cancellation, persisted retries, or CRON scheduling. Ad hoc jobs and scheduled occurrences use the same execution state machine. -## The IJob Interface - -[View source](https://github.com/FoundatioFx/Foundatio/blob/main/src/Foundatio/Jobs/IJob.cs) - -Every job implements a single method: - -```csharp -public interface IJob -{ - Task RunAsync(CancellationToken cancellationToken = default); -} -``` - -You can implement `IJob` directly, but in practice you'll derive from one of the base classes below. - -## Choosing a Job Type - -| Scenario | Base Class | When to Use | -|----------|-----------|-------------| -| Scheduled or periodic work | `JobBase` | Maintenance tasks, report generation, data sync | -| Singleton / leader-elected work | `JobWithLockBase` | Only one instance should run across all servers | -| Processing queue items | `QueueJobBase` | Each unit of work arrives as a queue message | -| On-demand heterogeneous tasks | `WorkItemJob` + handlers | User-triggered operations, bulk operations with progress | - -### Architectural Tradeoffs - -**`JobBase` vs `QueueJobBase`:** A `JobBase` that polls a database on an interval is simpler to reason about but wastes cycles when there's no work. A `QueueJobBase` reacts instantly to new messages and naturally distributes load across instances, but adds a queue dependency. Use `QueueJobBase` when work arrives unpredictably and latency matters; use `JobBase` when work is periodic or the polling interval is acceptable. - -**`QueueJobBase` vs `WorkItemJob`:** `QueueJobBase` creates one strongly-typed queue per job — ideal when you have a steady stream of homogeneous work (order processing, email sending, image resizing). `WorkItemJob` uses a single shared `IQueue` to multiplex many task types through one queue and job pool. Prefer `WorkItemJob` when tasks are sporadic, one-off, or varied (user-triggered deletes, bulk exports, cache rebuilds) — it avoids creating a dedicated queue and job class for each operation. `WorkItemJob` also supports built-in progress reporting, making it natural for operations that a user is waiting on. - -**Lock timeouts and self-healing:** Locks acquired via `JobWithLockBase` or `ILockProvider.AcquireAsync` have a `timeUntilExpires` parameter (default: 20 minutes). If a server crashes while holding a lock, the lock *automatically releases* after this timeout — no manual intervention needed. Set `timeUntilExpires` to a duration comfortably longer than your expected job duration so the lock doesn't expire mid-run, but short enough that a crash doesn't block the next run for too long. For jobs where you can measure average duration, set the timeout to roughly 2-3x that average. For long or unpredictable jobs, use a shorter timeout and call `context.RenewLockAsync()` periodically to extend the lease. When acquiring a lock in `GetLockAsync`, pass `new CancellationToken(true)` to make the attempt non-blocking — `AcquireAsync` checks `cancellationToken.IsCancellationRequested` to decide whether to wait; an already-cancelled token means "try once and return `null` if the lock is held." This lets interval-based jobs gracefully skip a run rather than pile up waiting for a busy lock. The queue's `WorkItemTimeout` serves the same self-healing purpose for queue entries: entries that aren't completed or renewed within the timeout are redelivered to another consumer. - -## Standard Jobs - -### JobBase - -[View source](https://github.com/FoundatioFx/Foundatio/blob/main/src/Foundatio/Jobs/JobBase.cs) - -`JobBase` provides structured logging (`_logger`), a `TimeProvider`, and a `ResiliencePolicyProvider`. All base classes accept optional `TimeProvider` and `IResiliencePolicyProvider` constructor parameters (defaulting to `TimeProvider.System` and `DefaultResiliencePolicyProvider.Instance`). You override `RunInternalAsync` and receive a `JobContext`: +## Start a job worker ```csharp +using Foundatio; using Foundatio.Jobs; -public class CleanupJob : JobBase -{ - public CleanupJob( - TimeProvider timeProvider, - IResiliencePolicyProvider resiliencePolicyProvider, - ILoggerFactory loggerFactory) - : base(timeProvider, resiliencePolicyProvider, loggerFactory) { } - - protected override async Task RunInternalAsync(JobContext context) - { - var deletedCount = await CleanupOldRecordsAsync(context.CancellationToken); - _logger.LogInformation("Cleaned up {Count} records", deletedCount); - return JobResult.Success; - } -} -``` - -### JobContext - -`JobContext` is passed to `RunInternalAsync` and carries everything your job needs at runtime: - -| Member | Description | -|--------|-------------| -| `CancellationToken` | Signals that the job should stop gracefully | -| `Lock` | The distributed lock held by the job (`null` unless using `JobWithLockBase`) | -| `RenewLockAsync()` | Extends the lock lease — call this in long-running loops to prevent expiration. In `QueueEntryContext`, also renews the queue entry's visibility timeout so the message isn't redelivered to another consumer. | - -```csharp -protected override async Task RunInternalAsync(JobContext context) -{ - foreach (var batch in GetBatches()) - { - context.CancellationToken.ThrowIfCancellationRequested(); - await ProcessBatchAsync(batch); - await context.RenewLockAsync(); // keep the lock alive between batches - } - - return JobResult.Success; -} +builder.Services.AddFoundatioWorker(foundatio => foundatio + .Jobs.UseInMemory() + .Jobs.AddJobType("resize-image.v1") + .Jobs.AddCronJob("0 2 * * *")); ``` -### JobWithLockBase - -[View source](https://github.com/FoundatioFx/Foundatio/blob/main/src/Foundatio/Jobs/JobWithLockBase.cs) - -`JobWithLockBase` automatically acquires a distributed lock before each run and releases it afterward. If the lock cannot be acquired, the run is cancelled — your code is never called. This makes it ideal for leader-election scenarios where exactly one instance should execute across a cluster. +The in-memory store is for tests and local development. Use `.Jobs.UseRedis()` for persistence across processes, with Redis persistence and availability configured for your requirements. -Override two methods: +`AddFoundatioWorker(..., jobConcurrency: 4)` runs up to four jobs concurrently. Its scheduler runs independently. For a producer-only API, use `AddFoundatio()` to register the same store and job types. For separate scheduler and worker processes, use the [individual hosting methods](dependency-injection.md#choose-host-roles-explicitly). -- **`GetLockAsync`** — return the lock to acquire, or `null` to skip the run. -- **`RunInternalAsync`** — your job logic, called only while the lock is held. +## Typed arguments and handles ```csharp -using Foundatio.Jobs; -using Foundatio.Lock; +public sealed record ResizeArgs(string File, int Width); -[Job(Description = "Singleton maintenance job", Interval = "5s")] -public class MaintenanceJob : JobWithLockBase +public sealed class ResizeImageJob(ImageService images) : IJob { - private readonly ILockProvider _lockProvider; - - public MaintenanceJob( - ICacheClient cache, - IMessageBus messageBus, - TimeProvider timeProvider, - IResiliencePolicyProvider resiliencePolicyProvider, - ILoggerFactory loggerFactory) : base(timeProvider, resiliencePolicyProvider, loggerFactory) + public async Task RunAsync(ResizeArgs arguments, JobExecutionContext context) { - _lockProvider = new CacheLockProvider(cache, messageBus, loggerFactory); - } - - protected override Task GetLockAsync(CancellationToken cancellationToken) - { - // Pass an already-cancelled token so AcquireAsync attempts the lock - // exactly once without waiting.

A token that is already cancelled tells the provider "try once — if the lock is held, return `null` immediately." This is the standard pattern for jobs that run on an interval and should simply skip the current iteration if another instance is already running. - -**`JobWithLockBase` vs manual locking in `JobBase`:** - -- Use **`JobWithLockBase`** when the *entire run* must be single-instance. The lock wraps the full execution and is released automatically — even on exceptions. Set `timeUntilExpires` in `GetLockAsync` to at least 2-3x your expected run duration so the lock self-heals after a crash but doesn't expire during normal operation. -- Use **manual `ILockProvider.AcquireAsync`** inside `JobBase` when you need finer-grained control — for example, locking individual resources while allowing the job itself to run on multiple servers: - -```csharp -public class ResourceSyncJob : JobBase -{ - private readonly ILockProvider _locker; - private readonly IResourceRepository _repository; - - public ResourceSyncJob( - ILockProvider locker, - IResourceRepository repository, - TimeProvider timeProvider, - IResiliencePolicyProvider resiliencePolicyProvider, - ILoggerFactory loggerFactory) - : base(timeProvider, resiliencePolicyProvider, loggerFactory) - { - _locker = locker; - _repository = repository; - } - - protected override async Task RunInternalAsync(JobContext context) - { - var pendingResources = await _repository.GetPendingSyncAsync(context.CancellationToken); - if (pendingResources.Count == 0) - return JobResult.Success; - - _logger.LogInformation("Found {Count} resources to sync", pendingResources.Count); - - foreach (var resource in pendingResources) - { - context.CancellationToken.ThrowIfCancellationRequested(); - - await using var lck = await _locker.AcquireAsync( - $"resource-sync:{resource.Id}", - cancellationToken: new CancellationToken(true)); - - if (lck is null) - { - _logger.LogDebug("Skipping resource {ResourceId}, another instance is syncing it", resource.Id); - continue; - } - - await _repository.SyncAsync(resource, context.CancellationToken); - } - - return JobResult.Success; - } -} -``` - -### IJobWithOptions - -`IJobWithOptions` extends `IJob` with a `JobOptions` property. `JobWithLockBase` implements this interface, and `JobRunner` uses it to pass runtime configuration (name, interval, iteration limit) to job instances. You rarely need to implement it directly. - -```csharp -public interface IJobWithOptions : IJob -{ - JobOptions? Options { get; set; } -} -``` - -### Running Jobs - -```csharp -var job = serviceProvider.GetRequiredService(); - -// Run once -await job.RunAsync(); - -// Run continuously with a 5-minute pause between iterations -await job.RunContinuousAsync( - interval: TimeSpan.FromMinutes(5), - cancellationToken: stoppingToken); - -// Run exactly 100 iterations then stop -await job.RunContinuousAsync( - iterationLimit: 100, - cancellationToken: stoppingToken); -``` - -`RunContinuousAsync` handles the loop, error delays, and cancellation for you. For queue-based jobs, the return value is the number of items processed successfully; for standard jobs, it's the iteration count. - -### Job Results - -`JobResult` communicates the outcome of each run to the framework. When running continuously, a failed result triggers an automatic delay before the next iteration to avoid tight error loops: - -```csharp -protected override Task RunInternalAsync(JobContext context) -{ - try - { - // Success - return Task.FromResult(JobResult.Success); - - // Success with message - return Task.FromResult(JobResult.SuccessWithMessage("Processed 100 items")); - - // Failed with message - return Task.FromResult(JobResult.FailedWithMessage("Database connection failed")); - - // Cancelled - return Task.FromResult(JobResult.Cancelled); - } - catch (Exception ex) - { - // From exception - return Task.FromResult(JobResult.FromException(ex)); - } -} -``` - -| Factory | `IsSuccess` | Behavior in continuous mode | -|---------|------------|---------------------------| -| `Success` / `SuccessWithMessage` | `true` | Waits `Interval` then runs again | -| `FailedWithMessage` / `FromException` | `false` | Waits at least 100ms (or `Interval`, whichever is longer) | -| `Cancelled` / `CancelledWithMessage` | N/A | Logged as warning; loop continues | - -## Queue Processor Jobs - -### QueueJobBase\ - -[View source](https://github.com/FoundatioFx/Foundatio/blob/main/src/Foundatio/Jobs/QueueJobBase.cs) - -`QueueJobBase` processes items from an `IQueue`. Each call to `RunAsync` dequeues one item and calls your `ProcessQueueEntryAsync` method. It handles dequeue timeouts, cancellation, poison messages (null values), and optional per-entry locking automatically. - -**Key behaviors:** - -- **AutoComplete (default: `true`)** — entries are completed when `ProcessQueueEntryAsync` returns success, or abandoned on failure/exception. Set `AutoComplete = false` when you need to call `CompleteAsync()` / `AbandonAsync()` yourself. -- **Entry-level locking** — override `GetQueueEntryLockAsync` to acquire a distributed lock per queue entry before processing. The default returns an empty (no-op) lock. If `GetQueueEntryLockAsync` returns `null`, the entry is abandoned.

Attach them when creating the queue: - -```csharp -var cache = new InMemoryCacheClient(); -var queue = new InMemoryQueue(o => o - .AddBehavior(new DuplicateDetectionQueueBehavior( - cache, loggerFactory, detectionWindow: TimeSpan.FromMinutes(10)))); -``` - -`DuplicateDetectionQueueBehavior` discards duplicate entries based on `IHaveUniqueIdentifier.UniqueIdentifier`. Implement the interface on your work item type: - -```csharp -public record OrderWorkItem : IHaveUniqueIdentifier -{ - public int OrderId { get; init; } - public string? UniqueIdentifier => $"order:{OrderId}"; -} -``` - -You can create custom behaviors by extending `QueueBehaviorBase` and overriding any combination of `OnEnqueuing`, `OnEnqueued`, `OnDequeued`, `OnCompleted`, `OnAbandoned`, `OnLockRenewed`, and `OnQueueDeleted`. - -## Work Item Jobs - -Work item jobs solve a different problem than queue jobs: they process **heterogeneous** tasks from a single shared queue. A `WorkItemJob` dequeues `WorkItemData` messages and dispatches each one to a type-specific handler. This is ideal for user-triggered operations (bulk deletes, imports, exports) where you want progress reporting and don't want to create a separate queue per task type. - -### Define a Work Item Handler - -Create handlers by extending `WorkItemHandlerBase`: - -```csharp -using Foundatio.Jobs; - -public class DeleteEntityWorkItemHandler : WorkItemHandlerBase -{ - private readonly IEntityService _entityService; - - public DeleteEntityWorkItemHandler( - IEntityService entityService, - ILogger logger) : base(logger) - { - _entityService = entityService; - } - - public override async Task HandleItemAsync(WorkItemContext ctx) - { - var workItem = ctx.GetData(); - - await ctx.ReportProgressAsync(0, "Starting deletion..."); - - // Delete children with progress reporting - var children = await _entityService.GetChildrenAsync(workItem.EntityId); - var total = children.Count; - var current = 0; - - foreach (var child in children) - { - await _entityService.DeleteAsync(child.Id); - current++; - await ctx.ReportProgressAsync( - (current * 100) / total, - $"Deleted {current} of {total} children"); - } - - await _entityService.DeleteAsync(workItem.EntityId); - await ctx.ReportProgressAsync(100, "Deletion complete"); - } -} - -public record DeleteEntityWorkItem -{ - public int EntityId { get; init; } -} -``` - -### WorkItemContext - -`WorkItemContext` is passed to `HandleItemAsync` and provides everything a handler needs: - -| Member | Description | -|--------|-------------| -| `GetData()` | Deserializes the raw payload to your work item type | -| `Data` | The raw work item payload (use `GetData()` instead) | -| `JobId` | Unique identifier for this job run | -| `WorkItemLock` | Optional distributed lock for the work item | -| `CancellationToken` | Signals that processing should stop | -| `Result` | Set to `JobResult.FailedWithMessage(...)` to indicate failure without throwing.

You can register handlers in several ways: - -```csharp -var handlers = new WorkItemHandlers(); - -// Instance registration -handlers.Register( - new DeleteEntityWorkItemHandler(entityService, logger)); - -// Factory registration (lazy — creates a new handler per invocation) -handlers.Register( - () => sp.GetRequiredService()); - -// Inline delegate (for simple tasks that don't need a full handler class) -handlers.Register(async ctx => -{ - var data = ctx.GetData(); - await ProcessAsync(data); -}); -``` - -### Register and Run Work Item Jobs - -```csharp -// DI registration -services.AddSingleton>(sp => new InMemoryQueue()); -services.AddSingleton(sp => new InMemoryMessageBus()); -services.AddSingleton(sp => sp.GetRequiredService()); -services.AddScoped(); -services.AddSingleton(sp => -{ - var handlers = new WorkItemHandlers(); - handlers.Register( - () => sp.GetRequiredService()); - return handlers; -}); - -// Run with multiple instances for parallel processing -var job = serviceProvider.GetRequiredService(); -await new JobRunner(job, serviceProvider, instanceCount: 2).RunAsync(stoppingToken); -``` - -### Trigger Work Items - -Use the `EnqueueAsync` extension method to enqueue strongly-typed work items: - -```csharp -var queue = serviceProvider.GetRequiredService>(); - -// Enqueue a work item (returns a job ID for tracking) -string jobId = await queue.EnqueueAsync(new DeleteEntityWorkItem { EntityId = 123 }); - -// With progress reporting enabled -string jobId = await queue.EnqueueAsync( - new DeleteEntityWorkItem { EntityId = 123 }, - includeProgressReporting: true); - -// Subscribe to progress updates -var messageBus = serviceProvider.GetRequiredService(); -await messageBus.SubscribeAsync(status => -{ - Console.WriteLine($"[{status.WorkItemId}] {status.Progress}% - {status.Message}"); -}); -``` - -## Job Runner - -[View source](https://github.com/FoundatioFx/Foundatio/blob/main/src/Foundatio/Jobs/JobRunner.cs) - -`JobRunner` orchestrates job execution with support for continuous running, multiple parallel instances, initial delays, and console hosting: - -```csharp -using Foundatio.Jobs; - -var job = serviceProvider.GetRequiredService(); -var runner = new JobRunner(job, serviceProvider); - -// Run until cancelled -await runner.RunAsync(stoppingToken); - -// Run in background (fire-and-forget) -runner.RunInBackground(); - -// Multiple parallel instances -var multiRunner = new JobRunner(job, serviceProvider, instanceCount: 4); -await multiRunner.RunAsync(stoppingToken); -``` - -### Console App Hosting - -`RunInConsoleAsync` sets up `Ctrl+C` and Azure WebJobs shutdown file handling, runs the job, and returns a process exit code: - -```csharp -var exitCode = await new JobRunner(job, serviceProvider).RunInConsoleAsync(); -Environment.Exit(exitCode); -// Returns: 0 = success, -1 = failure, 1 = unhandled exception -``` - -## Job Options - -### Job Attribute - -Configure job behavior declaratively with the `[Job]` attribute. These values become the defaults that `JobRunner` and the hosting infrastructure use: - -```csharp -[Job( - Name = "MyJob", - Description = "Processes pending items", - Interval = "5m", - InitialDelay = "10s", - IsContinuous = true, - IterationLimit = -1, - InstanceCount = 1 -)] -public class MyJob : JobBase -{ - public MyJob( - TimeProvider timeProvider, - IResiliencePolicyProvider resiliencePolicyProvider, - ILoggerFactory loggerFactory) - : base(timeProvider, resiliencePolicyProvider, loggerFactory) { } - - protected override Task RunInternalAsync(JobContext context) - { - return Task.FromResult(JobResult.Success); - } -} -``` - -| Property | Type | Default | Description | -|----------|------|---------|-------------| -| `Name` | `string?` | Type name minus "Job" suffix | Display name used in logging and status APIs | -| `Description` | `string?` | `null` | Human-readable description | -| `IsContinuous` | `bool` | `true` | Whether the job runs in a loop | -| `Interval` | `string?` | `null` | Delay between iterations (e.g., `"5m"`, `"30s"`) | -| `InitialDelay` | `string?` | `null` | Delay before first execution | -| `IterationLimit` | `int` | `-1` | Maximum iterations (`-1` = unlimited) | -| `InstanceCount` | `int` | `1` | Number of parallel instances | - -### JobOptions Class - -`JobOptions` holds the same settings programmatically.

Argument-free jobs implement `IJob.RunAsync(JobExecutionContext)`. A typed job cannot be submitted without its arguments. Register stable, versioned job names on both submitters and workers; only allowlisted job types execute. Keep the serialized argument contract compatible for as long as old jobs can remain queued or retained. -Register jobs as hosted services with a fluent builder: +Each execution receives a dependency injection scope, its application job ID, attempt number, and cancellation token.

Exhausted jobs end in `Failed` with their error retained. -// With configuration -services.AddJob(o => o - .Interval(TimeSpan.FromHours(1)) - .WaitForStartupActions() - .InitialDelay(TimeSpan.FromSeconds(30))); - -// Parallel queue processing -services.AddJob(o => o.InstanceCount(4)); -``` +An expired processing lease can be claimed with a fresh token. Host shutdown returns unfinished work to the queue; explicit user cancellation is terminal. A worker that loses its lease cannot complete or report progress against the replacement claim. -The builder exposes: `Name`, `Description`, `JobFactory`, `RunContinuous`, `Interval`, `InitialDelay`, `IterationLimit`, `InstanceCount`, and `WaitForStartupActions`. - -### Cron Job Scheduling - -Schedule jobs using cron expressions: - -```csharp -using Foundatio.Extensions.Hosting.Jobs; - -// Every 6 hours -services.AddCronJob("0 */6 * * *"); - -// Every Monday at midnight -services.AddCronJob("0 0 * * MON"); - -// With configuration -services.AddCronJob("0 2 * * *", o => o - .Name("nightly-maintenance") - .WaitForStartupActions()); - -// Inline action — no job class needed -services.AddCronJob("health-check", "*/5 * * * *", async (sp, ct) => -{ - var healthService = sp.GetRequiredService(); - await healthService.CheckAsync(ct); -}); -``` - -#### Cron Helper Class - -Use the `Cron` helper to generate common cron expressions without memorizing the syntax: - -```csharp -using Foundatio.Extensions.Hosting.Jobs; - -services.AddCronJob(Cron.Hourly()); // every hour at :00 -services.AddCronJob(Cron.Daily(hour: 2)); // daily at 2:00 AM -services.AddCronJob(Cron.Weekly(DayOfWeek.Monday, hour: 9)); // Monday at 9 AM -services.AddCronJob(Cron.Monthly(day: 1)); // 1st of each month -services.AddCronJob(Cron.Minutely(5)); // every 5 minutes -services.AddCronJob(Cron.Yearly(month: 1)); // January 1st -services.AddCronJob(Cron.Never()); // never (disabled) -``` - -#### Scheduled Job Options - -Cron jobs support additional configuration through `ScheduledJobOptionsBuilder`: - -```csharp -services.AddCronJob("0 0 * * *", o => o - .Name("daily-report") - .Description("Generates the daily summary report") - .WaitForStartupActions() - .CronTimeZone("America/New_York") - .Enabled(true)); -``` +These fences protect job state, not arbitrary external side effects. A process can crash after completing an external operation but before persisting completion. Jobs must tolerate repeated execution. A stable caller-supplied `JobRequestOptions.JobId` makes submission create-if-absent while that record is retained; it does not make execution exactly once. -### Distributed Cron Jobs +Workers atomically claim the oldest eligible due job from registered types and optional node affinity. Monitoring queries do not drive execution, so old or unknown job types cannot crowd runnable work out of a monitoring page. -Ensure only one instance runs a scheduled job across all servers. This requires an `ICacheClient` registration for distributed lock coordination: +## CRON schedules ```csharp -using Foundatio.Extensions.Hosting.Jobs; - -services.AddDistributedCronJob("0 0 * * *"); - -// Requires ICacheClient for distributed locking -services.AddSingleton(sp => new RedisCacheClient(...)); -``` - -### Job Manager - -`IJobManager` provides a runtime API for inspecting, triggering, and managing scheduled jobs. It is automatically registered when you use `AddCronJob` or `AddJobScheduler`: - -```csharp -var jobManager = serviceProvider.GetRequiredService(); - -// View all job statuses -JobStatus[] statuses = jobManager.GetJobStatus(); -foreach (var status in statuses) - Console.WriteLine($"{status.Name}: NextRun={status.NextRun}, LastRun={status.LastRun}"); - -// Trigger a job on-demand (runs immediately regardless of schedule) -await jobManager.RunJobAsync(); - -// Add or update a scheduled job at runtime -jobManager.AddOrUpdate(o => o.CronSchedule(Cron.Hourly())); - -// Disable a job without removing it -jobManager.Update(o => o.Disabled()); - -// Remove a job entirely -jobManager.Remove(); - -// Release a stuck distributed lock (e.g., after a server crash) -await jobManager.ReleaseLockAsync("Cleanup"); -``` - -### Manual BackgroundService - -When the `AddJob` extensions don't fit your needs, you can integrate any Foundatio job with `BackgroundService` directly: - -```csharp -public class CleanupJobHostedService : BackgroundService -{ - private readonly IServiceProvider _services; - private readonly ILogger _logger; - - public CleanupJobHostedService( - IServiceProvider services, ILogger logger) +builder.Services.AddFoundatioWorker(foundatio => foundatio + .Jobs.UseInMemory() + .Jobs.AddJobType("resize-image.v1") + .Jobs.AddCronJob("0 2 * * *", new ResizeArgs("banner.png", 640), o => { - _services = services; - _logger = logger; - } - - protected override async Task ExecuteAsync(CancellationToken stoppingToken) - { - while (!stoppingToken.IsCancellationRequested) - { - using var scope = _services.CreateScope(); - var job = scope.ServiceProvider.GetRequiredService(); - - try { await job.RunAsync(stoppingToken); } - catch (Exception ex) { _logger.LogError(ex, "Cleanup job failed"); } - - await Task.Delay(TimeSpan.FromHours(1), stoppingToken); - } - } -} - -services.AddScoped(); -services.AddHostedService(); + o.Name = "resize-banner"; + o.TimeZone = TimeZoneInfo.FindSystemTimeZoneById("America/Chicago"); + o.ConfigurationVersion = 1; + })); ``` -## Common Patterns - -### Job with Progress Reporting - -Use `IMessageBus` to publish progress from standard jobs: - -```csharp -public class ImportJob : JobBase -{ - private readonly IMessageBus _messageBus; - - public ImportJob( - IMessageBus messageBus, - TimeProvider timeProvider, - IResiliencePolicyProvider resiliencePolicyProvider, - ILoggerFactory loggerFactory) - : base(timeProvider, resiliencePolicyProvider, loggerFactory) - { - _messageBus = messageBus; - } - - protected override async Task RunInternalAsync(JobContext context) - { - var items = await GetItemsToImportAsync(); - var total = items.Count; - - for (int i = 0; i < total; i++) - { - if (context.CancellationToken.IsCancellationRequested) - return JobResult.Cancelled; - - await ImportItemAsync(items[i]); - await _messageBus.PublishAsync(new ImportProgress - { - ProcessedCount = i + 1, - TotalCount = total, - PercentComplete = ((i + 1) * 100) / total - }); - } +Five-field expressions use minute resolution; six-field expressions include seconds. Definitions persist a wire job name, serialized argument payload, time-zone ID, retry budget, enabled state, scope, overlap policy, and revision. They contain no CLR `Type`, delegates, or live argument objects. - return JobResult.Success; - } -} -``` +Global schedules create one occurrence per tick across scheduler replicas. `PerNode` creates occurrences with affinity to each scheduler node; the worker on that node must use the same node identity and register the job type. `FOUNDATIO_NODE_ID` sets a stable identity when required. The default is process-unique. -### Retry vs Permanent Failure +`SkipIfRunning` prevents a new occurrence while an earlier occurrence remains queued, processing, or waiting for retry. Explicitly allowing overlap permits concurrent occurrences. Unique occurrence IDs prevent duplicate materialization across concurrent scheduler polls. Manual triggers also respect overlap and disabled state. -Distinguish between transient errors (retry is useful) and permanent errors (retry would loop forever). Whether returning a failed `JobResult` actually triggers a retry depends on the job type: +The misfire window defaults to one minute and is limited to one day. Only ticks inside that window are caught up; this is not a promise to replay every tick after an unlimited outage. Keep high-frequency catch-up windows small. A skipped overlapping tick can be considered again while it remains in the window. -- **Queue-processed jobs** (`QueueJobBase`, `WorkItemJob`) -- a non-success result abandons the queue entry, which re-queues it for retry and eventually moves it to the [dead letter queue](./queues#dead-letter-queue) once `Retries` is exhausted. Return `FailedWithMessage`/`FromException` only for errors you want retried; for permanent errors, log it yourself and return `JobResult.Success` (or `SuccessWithMessage`) so the entry completes instead of retrying forever and dead-lettering. +### Persisted edits and deployment reconciliation -```csharp -protected override async Task ProcessQueueEntryAsync(QueueEntryContext context) -{ - try - { - await DoWorkAsync(context.CancellationToken); - return JobResult.Success; - } - catch (TransientException ex) - { - return JobResult.FailedWithMessage(ex.Message); // entry is abandoned, retried, and eventually dead-lettered - } - catch (PermanentException ex) - { - _logger.LogError(ex, "Permanent failure, not retrying"); - return JobResult.Success; // complete the entry instead of retrying/dead-lettering - } -} -``` +`IScheduledJobManager` lists, inspects, reschedules, enables/disables, removes, and manually triggers schedules. `TriggerAsync(name)` returns a durable job handle. `ScheduleAsync` creates a typed runtime schedule. -- **Standalone/manual jobs** (`JobBase`, a one-off `RunAsync()`/`RunInConsoleAsync()` run, or scheduled/cron jobs via `Foundatio.Extensions.Hosting`) -- there is no built-in retry or dead letter queue. A failed result just reflects the outcome: an error-level log entry, a non-zero exit code from `RunInConsoleAsync`, or a failed run in the scheduled job history. Returning `FailedWithMessage`/`FromException` for a permanent error is correct here; nothing inside Foundatio retries it, and any retry decision belongs to whatever runs the job (a scheduler, CI pipeline, or Kubernetes restart policy). +Updates to `ScheduledJobDefinition` use its `Revision`; a stale update fails rather than silently replacing another operator's edit. Declarative configuration has a separate `ConfigurationVersion`. Restarting the same deployment preserves runtime edits. Changing a declaration requires increasing that configuration version; older deployments cannot overwrite newer definitions. An intentional higher version applies the new declaration and advances the stored revision. -```csharp -protected override async Task RunInternalAsync(JobContext context) -{ - try - { - await DoWorkAsync(context.CancellationToken); - return JobResult.Success; - } - catch (Exception ex) - { - // Nothing in Foundatio retries a standalone job -- return the real outcome either way - return JobResult.FromException(ex); - } -} -``` +Disabling or removing a schedule stops future materialization; already queued occurrences remain independent jobs. Cancel those explicitly if needed. -### Idempotent Jobs +## Monitoring, retention, and capacity -Track progress externally so the job can safely resume after a crash: +`IJobMonitor.GetAsync(id)` retrieves a job. `QueryAsync(JobQuery)` returns a `JobPage`, ordered by job ID, with optional name/status filters. Limits range from 1 to 1,000 and default to 100. Continue using the returned token and the same filters: ```csharp -protected override async Task RunInternalAsync(JobContext context) +string? cursor = null; +do { - var lastProcessedId = await _state.GetLastProcessedIdAsync(); - var items = await _db.GetItemsAfterAsync(lastProcessedId); - - foreach (var item in items) - { - context.CancellationToken.ThrowIfCancellationRequested(); - await ProcessItemAsync(item); - await _state.SetLastProcessedIdAsync(item.Id); - } - - return JobResult.Success; -} -``` - -## Best Practices - -1. **Always propagate cancellation tokens.** Pass `context.CancellationToken` to every async call and check it in loops. This ensures your job shuts down promptly during host shutdown. - -2. **Renew locks in long-running jobs.** If your job holds a distributed lock (via `JobWithLockBase` or queue entry locking), call `context.RenewLockAsync()` periodically — especially between batches. Lock expiration mid-run causes correctness issues. - -3. **Keep jobs idempotent.** Jobs may be killed at any point (process recycle, deployment, crash). Track progress so they can pick up where they left off rather than re-processing everything. - -4. **Log with structured context.** Use `BeginScope` to correlate all log entries for a unit of work: - -```csharp -using var _ = _logger.BeginScope(s => s.Property("OrderId", workItem.OrderId)); -_logger.LogInformation("Processing order..."); -// every log inside this scope automatically includes OrderId + var page = await monitor.QueryAsync(new JobQuery { Status = JobStatus.Failed, AfterJobId = cursor }); + foreach (var job in page) + Console.WriteLine($"{job.JobId}: {job.Error}"); + cursor = page.ContinuationToken; +} while (cursor is not null); ``` -5. **Match job type to workload.** Don't force a `QueueJobBase` when a simple `JobBase` with `RunContinuousAsync` suffices. Don't create separate queues for every task type — use `WorkItemJob` for heterogeneous on-demand work. - -6. **Use distributed cron for cluster-wide scheduling.** If you have multiple servers running the same host, use `AddDistributedCronJob` to ensure only one server executes the scheduled run. - -## Dependency Injection - -### Register Standard Jobs +Redis reads bounded index pages rather than loading every job. A filtered page can be empty and still have a continuation token. Pages are a live view; concurrent inserts or status changes are not a snapshot. -```csharp -services.AddScoped(); -services.AddScoped(); -services.AddSingleton>(sp => new InMemoryQueue()); -``` - -### Register Queue Jobs with Parallel Processing +Terminal records are retained for seven days after completion. The worker host runs bounded cleanup automatically; manual hosts call `IJobRuntimeStore.CleanupAsync()`. Active jobs are never removed by retention. Once a record is removed, its ID can be submitted again; application idempotency may require a longer-lived record in your business database. -```csharp -services.AddSingleton>(sp => new InMemoryQueue()); -services.AddJob(o => o.InstanceCount(4)); -``` +Stores default to 100,000 retained job records. Set `RedisJobRuntimeStoreOptions.MaxJobs` or the in-memory constructor's `maxJobs` for the deployment. At capacity, new submissions fail with `JobException`, preserving existing work. Cleanup releases capacity. This count includes retained terminal records, so size it for peak backlog plus seven days of history. Payload sizes and Redis persistence remain deployment responsibilities. -## Next Steps +## Testing and migration -- [Queues](./queues) — Queue implementations for job processing -- [Locks](./locks) — Distributed locking for singleton jobs -- [Resilience](./resilience) — Retry policies for job reliability -- [Serialization](./serialization) — Serializer configuration and performance +`Foundatio.Testing.JobsTestHarness` runs the real worker/scheduler with in-memory state and a controlled clock. `RunAllQueuedAsync()` drains currently eligible work across batches; future delayed jobs remain queued. `RunToCompletionAsync(handle)` runs only that job. `RunDueAsync()` materializes due CRON occurrences and drains eligible jobs; it does not dispatch scheduled messages. Shared `JobRuntimeStoreConformanceTests` cover ownership fencing, eligibility, concurrency, retries, cancellation, schedule revisions, dispatch recovery, pagination, and retention against memory and Redis. +Old `JobBase`, `QueueJobBase`, `JobWithLockBase`, `JobRunner`, and `WorkItemJob` implementations migrate to plain `IJob` or `IMessageHandler`. Replace `RunAsync(CancellationToken)` with `RunAsync(JobExecutionContext)`, queue jobs with explicit message consumers, and work-item payloads with `IJob`. The old automatic runtime pump and generic state-patch store API are removed; host roles and ownership-specific store operations are explicit. diff --git a/docs/guide/locks.md b/docs/guide/locks.md index d8ffdcb1f..9cce8cc9c 100644 --- a/docs/guide/locks.md +++ b/docs/guide/locks.md @@ -58,7 +58,7 @@ using Foundatio.Caching; using Foundatio.Messaging; var cache = new InMemoryCacheClient(); -var messageBus = new InMemoryMessageBus(); +var messageBus = new MessageBus(new InMemoryMessageTransport()); var locker = new CacheLockProvider(cache, messageBus); await using var lck = await locker.TryAcquireAsync("my-resource"); @@ -436,7 +436,7 @@ public async Task ProcessRequest(string userId) ```csharp services.AddSingleton(); -services.AddSingleton(); +services.AddFoundatio().Messaging.UseInMemory(); services.AddSingleton(sp => new CacheLockProvider( diff --git a/docs/guide/messaging-jobs-redesign.md b/docs/guide/messaging-jobs-redesign.md index 566640470..be78dc8ba 100644 --- a/docs/guide/messaging-jobs-redesign.md +++ b/docs/guide/messaging-jobs-redesign.md @@ -1,287 +1,9 @@ -# Messaging and Jobs Redesign +# Messaging and jobs redesign -The redesigned messaging API is one client — `IMessageBus` in `Foundatio.Messaging` — with two verbs. The caller's verb carries the delivery semantic, and handlers are registered without any topology decision: +This unreleased redesign uses explicit queue consumers and event subscribers, with an optional durable job runtime. See [Messaging](messaging.md) and [Durable jobs](jobs.md) for current APIs, runnable examples, guarantees, and migration guidance. -- `SendAsync` — a **command** / unit of work: exactly one handler instance across the fleet processes it (competing consumers). -- `PublishAsync` — an **event**: every subscribing service receives one copy (a scaled service's instances compete for it), or every instance when the subscription opts into `PerInstance`. +The common setup is a message bus plus a handler. Add durable jobs only when persisted execution state, progress, cancellation, retries, or CRON schedules are needed. Use `AddFoundatioWorker(configure)` for a combined worker. Plain `AddFoundatio()` registers clients without starting execution; individual hosting methods support separate role deployments. -```csharp -await bus.SendAsync(new ResizeImage(id)); // one handler instance, somewhere, does the work -await bus.PublishAsync(new OrderSubmitted(id)); // every subscribing service hears about it -``` +The transport handles bytes, metadata, receipts, and broker operations. The messaging core owns routing, serialization, retry policy, lease supervision, and settlement. The job store owns atomic admission, claims, fenced mutations, schedule definitions, and retention. Ad hoc jobs and CRON occurrences run through one worker state machine. -Every verb returns the accepted message id(s): `SendAsync`/`PublishAsync` return the message id, and the batch verbs return `IReadOnlyList` in input order, so callers can correlate and trace each accepted message. `SendBatchAsync` and `PublishBatchAsync` batch both verbs; the non-generic `IEnumerable` overloads accept heterogeneous batches and group by resolved route. Per-operation options are `MessageSendOptions` and `MessagePublishOptions` (priority, delay/`DeliverAt`, TTL, correlation id, headers, and a `Destination`/`Topic` override as the escape hatch). - -The two verbs also differ in what happens when nothing is listening. A sent command lands on a queue and waits durably for a handler. A published event has real pub/sub drop semantics: a publish to a topic with **no existing subscriptions is dropped** — subscriptions are created when handlers subscribe (or via topology provisioning), so subscribers must exist before the publish. The in-memory transport warns once per topic when a publish is dropped this way (the classic "I published and nothing happened" trap), and the core logs every produce at debug (`Sending {MessageType} to {Destination}`) so a quiet bus is diagnosable. - -The legacy implementations are gone. What remains for migration is a thin, opt-in bridge: the old `IMessageBus`/`IMessagePublisher`/`IMessageSubscriber` interface definitions plus `LegacyMessageBusAdapter`, registered with `Messaging.AddLegacyAdapter()`, which maps old-style publish/subscribe calls onto the new bus (see the Migration section). - -## The core owns behavior; transports stay simple - -The division of responsibility is deliberate: **the core owns behavior, transports stay thin.** A transport is bytes in, bytes out plus a few primitives — `IMessageTransport` is `SendAsync`, `CompleteAsync`, `AbandonAsync`, and small opt-in operation interfaces (`ISupportsPull`, `ISupportsPush`, `ISupportsDeadLetter`, `ISupportsRedeliveryDelay`, `ISupportsVisibilityTimeout`, `ISupportsLockRenewal`, `ISupportsStats`, `ISupportsProvisioning`). Everything that defines *how messaging behaves* — serialization, routing, multi-type dispatch, settlement, scheduling, and especially **retry and dead-lettering** — lives in the core and is therefore identical across every transport. There is exactly one retry authority (the core), never a tug-of-war between core policy and a broker-native redrive policy. - -Every transport API takes the same canonical identity: `DestinationAddress` (`Name`, `Role` — `Queue`/`Topic`/`Subscription`/`Binding` — and, for subscriptions, the owning `Topic`; created via `ForQueue`/`ForTopic`/`ForSubscription`). `Key` is its opaque string form (`"{topic}/{name}"` for subscriptions), so the same logical destination can never be spelled two ways on the send path versus the provisioning path. - -Facts a transport advertises are **per-destination**: the core asks `ITransportInfo.GetCapabilities(destination)` with the `DestinationAddress` in question and gets a `TransportCapabilities` record (`DelayedDelivery`, `MaxDeliveryDelay`, `Priority`, `Expiration`, `Ordering`, `MaxBatchSize`, `MaxMessageBytes`). Most transports answer by the destination's role, and capabilities genuinely differ by role on real brokers — the AWS transport's queue role has a native 15-minute `MaxDeliveryDelay` (SQS `DelaySeconds`) while its topic role has no native delay at all. Anything not advertised is treated as unsupported: the core validates, falls back to the runtime store, or fails loudly — a broker never silently drops a requested behavior. - -## Setup - -```csharp -services.AddFoundatio() - .Messaging - .ConfigureRouting(r => r - .UseServiceIdentity("billing") - .MapQueue("orders") - .MapTopic("order-events", typeof(IOrderEvent))) - .ConfigureRetry(p => p with { MaxAttempts = 5 }) - .ConfigureTopology(TopologyMode.Ensure) - .AddMessageType("order.submitted") - .UseInMemory() - .Messaging.AddHandler() - .Jobs.UseInMemory() - .Jobs.AddJobType("search.rebuild"); -``` - -Swap providers by swapping one line: `.Messaging.UseRedis()` (Redis Streams), `.Messaging.UseAws()` (SQS/SNS), `.Jobs.UseRedis()`, or `.Messaging.UseTransport(...)` / `.Jobs.UseRuntimeStore(...)` for anything custom. Application code depends on `IMessageBus`, `IJobClient`, and `IJobMonitor`; deployment or admin code can depend on `IMessageTopology`. The zero-dependency starting point is **`samples/Foundatio.QuickstartSample`** — a console app on the generic host that runs messaging and jobs entirely in-memory with plain `dotnet run` (event, command, durable job with typed args, and a CRON job). - -`AddMessageType(name)` gives a type a stable wire discriminator so payloads survive assembly/namespace moves; unregistered types fall back to `Type.FullName` (never `AssemblyQualifiedName`). `.Jobs.AddJobType(name)` does the same for persisted job types. - -**Misconfiguration fails at boot, not silently.** Registering CRON jobs without a runtime store, or message handlers without a transport, fails at host start with an actionable message naming the missing `Use*` call. An invalid cron expression or a duplicate schedule name throws even earlier — at the `AddCronJob` registration call. And startup topology (`Ensure`/`Validate`) runs for every app with a transport, publish-only apps included, so a missing destination surfaces at boot instead of as a runtime send error. - -## Handlers - -Handlers are topology-free. A handler implements `IMessageHandler` and is registered declaratively; it never decides queue-vs-topic — the sender's verb does: - -```csharp -public class SendConfirmationHandler : IMessageHandler -{ - public Task HandleAsync(IMessageContext context, CancellationToken cancellationToken) - => _email.SendConfirmationAsync(context.Message.OrderId, cancellationToken); -} - -services.AddFoundatio() - .Messaging.AddHandler(o => - { - o.MaxConcurrency = 4; - o.DeadLetterOn(); - }); -``` - -Each message is dispatched to the handler in its own DI scope (scoped dependencies work), and a single auto-registered hosted service (`MessageHandlerHostedService`) starts every registered handler at app start and disposes them at shutdown. Throwing from `HandleAsync` triggers the core retry/dead-letter policy. Each handler class defaults to its own subscriber group (the `SubscriptionQualifier` is set to the handler type name), so every handler registered for an event type receives its own copy of each published message. - -For dynamic subscriptions, `IMessageBus.SubscribeAsync(handler, options)` returns an `IMessageSubscription` handle (`Key`, `Destination`, `Topic`, `Subscription`, `Source`); disposing it detaches the handler. - -### Subscription options - -A subscription listens on the type's two delivery channels — sent commands and published events — and `MessageSubscriptionOptions` declares its intent: - -- **`Deliveries`** — `MessageDeliveries.Sent`, `Published`, or `Both` (default). A handler that only ever consumes commands (or only events) states that so no idle listener is wired — and so a queue-only or topic-only transport can serve it. The default `Both` quietly narrows to what the transport supports; explicitly requesting a single channel the transport cannot serve throws `NotSupportedException`. -- **`Subscription`** — the subscriber-group identity for published messages. Defaults to the service identity, so all instances of a service share one subscription and compete. **`SubscriptionQualifier`** distinguishes groups within one service (`"{service-identity}.{qualifier}"`). **`PerInstance`** gives every running instance its own unique subscription (cache invalidation, config reload) and is mutually exclusive with `Subscription`. -- **`MaxConcurrency`** — messages processed concurrently per instance. Default 1: the only default that preserves per-handler ordering, and each handler already gets its own concurrent stream (10 handlers = 10 parallel consumers). Raise it for I/O-bound, order-agnostic handlers. -- **`MaxAttempts`**, **`RedeliveryBackoff`**, **`DeadLetterWhen`** — per-subscription retry overrides; null inherits the default `RetryPolicy`. **`DeadLetterOn()`** is the by-type shorthand for `DeadLetterWhen` and composes (call once per exception type). -- **`AckMode`** — `Auto` (default) or `Manual`. -- **`RouteType`**, **`Destination`**, **`Topic`** — grouped/interface consumption and per-subscription route overrides. -- **`Key`** — consumer identity. Subscriptions sharing a `Key` on the same channel form one competing group and must configure identical failure policies; the backoff/`DeadLetterWhen` **delegates are compared by identity**, so share the same delegate instances — a lambda recreated per subscription is rejected as a conflicting registration. - -Delivery semantics are never invisible: each subscription logs its effective topology (destination, subscriber group, concurrency, retry posture) once at subscribe time. - -## Routing and topology - -`IMessageRouter` resolves the queue destination and topic for a message type. The default router's precedence: - -```text -operation override > exact type map > interface/base-type map > MessageRouteAttribute > configured default > convention > kebab-cased type name -``` - -Configure routes once with `ConfigureRouting` (a `MessageRoutingOptionsBuilder`): `UseDefaultQueue`, `UseDefaultTopic`, `MapQueue` / `MapQueue(destination, params Type[])`, `MapTopic` / `MapTopic(topic, params Type[])`, `UseServiceIdentity`, `UseSubscriptionIdentity`, and `UseConvention`. `UseServiceIdentity` names the service (the default subscriber-group identity); when unset it falls back to the `FOUNDATIO_SUBSCRIPTION_ID` / `FOUNDATIO_SERVICE_ID` environment variables, then the kebab-cased app name. - -**Routing configuration is also the topology declaration source.** `UseDefaultQueue`, `UseDefaultTopic`, `MapQueue`, and `MapTopic` declare the destinations they name, and setting a service/subscription identity declares the subscription on each configured topic — as `DestinationDeclaration` values carrying the *same* canonical `DestinationAddress` the runtime later sends to and receives from, so provisioning and runtime can never disagree on identity. Per-operation overrides are deliberately excluded: they are exceptional one-off routes. - -```csharp -IMessageTopology topology = provider.GetRequiredService(); -IReadOnlyList declarations = topology.GetDeclarations(); -await topology.EnsureAsync(); // deploy/admin process with create permissions -await topology.ValidateAsync(); // check-only; throws naming what is missing -``` - -`TopologyMode` (via `ConfigureTopology`) governs how the client administers topology at runtime and at startup: - -- **`Ensure`** (default) — create missing destinations on first use, and ensure the declared topology at startup. -- **`Validate`** — never create; verify each destination exists and throw when missing. Startup fails at boot instead of surfacing as runtime send errors. -- **`None`** — no topology calls at all; everything is pre-provisioned out of band. - -Startup topology is its own hosted service rather than riding the handler host, so it runs for **every** app with a transport — a publish-only app with no handlers still gets its declared destinations ensured (or validated) at boot. - -The mode governs the core's provisioning calls; combine `Validate`/`None` with transport knobs such as `AwsMessageTransportOptions.AutoCreateDestinations = false` for a fully locked-down broker. - -## Delivery settlement - -Received messages surface as `IMessageContext` / `IMessageContext` (id, body, headers, correlation id, priority, `Attempts`) and settle with two verbs: - -```csharp -await context.CompleteAsync(); // handled successfully -await context.RejectAsync(); // retry (redelivery) -await context.RejectAsync(new RejectOptions { RedeliveryDelay = TimeSpan.FromSeconds(30) }); -await context.RejectAsync(new RejectOptions { Terminal = true, Reason = "validation", Exception = ex }); -await context.RenewLockAsync(); // long handler heartbeat -``` - -A non-terminal reject returns the message for redelivery (optionally after `RedeliveryDelay`); `Terminal = true` means "never redeliver" and routes the message to the dead-letter sink with the `Reason` and `Exception` forensics attached. `RejectOptions.BestEffortDelay` lets a delay the transport cannot honor degrade to immediate redelivery instead of failing (the core's own retry policy uses best-effort delays; an explicit caller delay defaults to strict). - -Auto-ack is the default: a handler that returns without settling is completed, and a handler that throws is rejected per the retry policy. Manual settlement is opt-in with `AckMode.Manual`. - -## Retry and dead-lettering - -The core owns retry and dead-lettering, so behavior is identical on every transport. A transport only redelivers abandoned messages and optionally exposes a dead-letter sink; the core decides how many times to retry, how long to wait, and when to give up — using the broker's own delivery count as the crash-safe attempt counter, so the core owns the *policy* without owning durable retry *state*. - -The default `RetryPolicy`: `MaxAttempts` 5, and `RetryPolicy.DefaultBackoff` — an immediate first retry, then 10s/20s/30s (capped) with ±20% jitter, the delay shape mature messaging stacks converged on. Configure the default and override per subscription: - -```csharp -services.AddFoundatio() - .Messaging.ConfigureRetry(p => p with - { - MaxAttempts = 5, - Backoff = attempt => TimeSpan.FromSeconds(Math.Min(30, Math.Pow(2, attempt))), - DeadLetterWhen = ex => ex is ValidationException, // unrecoverable: dead-letter immediately - DeadLetterDestination = "orders-dead-letter" // null derives "{source}.deadletter" - }); -``` - -Deserialization failures are always treated as unrecoverable. Where a dead-lettered message lands, in order of preference: the transport's native dead-letter sink (`ISupportsDeadLetter`), otherwise the configured or derived (`"{source}.deadletter"`) dead-letter destination written by the core. Dead-lettered messages carry forensics headers — `message.dead_letter.reason`, `.attempts`, `.exception_type`, `.exception_message`, `.exception_stack`, `.failed_at`, and `.original_destination` (`KnownHeaders.DeadLetter*`) — so a dead message is triageable with plain transport tooling, and `ISupportsDeadLetter.ReceiveDeadLetteredAsync` reads raw entries back (including poison payloads that never deserialized). - -We deliberately do **not** configure broker-native redrive policies (SQS `maxReceiveCount`, Azure Service Bus `MaxDeliveryCount`, RabbitMQ DLX): that would split authority between broker and core and make behavior transport-specific. A destination's structural creation knobs, if any, are limited to `DestinationDeclaration.ProviderArguments`. - -### Delays and the runtime-store fallback - -A send delay or redelivery backoff is served natively when the transport supports it within its advertised ceiling (`TransportCapabilities.MaxDeliveryDelay`, `ISupportsRedeliveryDelay.MaxRedeliveryDelay`). A delay the broker cannot honor — beyond SQS's 15-minute delivery delay, or any delayed publish on SNS — is parked in the durable runtime store instead of being silently truncated: `MessageBusOptions.RuntimeStore` takes an `IScheduledDispatchStore` (any `IJobRuntimeStore` satisfies it; the DI builder wires it automatically when a runtime store is configured), and the job runtime pump dispatches parked messages when due. If neither native support nor a store is available, the operation fails loudly rather than dropping the delay. - -### Unmatched message types - -A message arriving on a shared destination whose type has no registered consumer on this node — a newer message type mid rolling-deploy, or a misconfiguration — is surfaced loudly: it increments the `foundatio.messaging.unhandled` metric and throws `UnhandledMessageTypeException`, isolated to that one message so the receive loop and the other type handlers keep running. It is retried so a node that *does* handle the type can pick it up, and finally dead-lettered as `"no-handler"` after `RetryPolicy.UnmatchedMaxAttempts` (default 50) — a genuinely orphaned type cannot loop forever. - -## Jobs - -`IJobClient` submits durable work and returns a `JobHandle`; `IJobWorker` claims and executes; `IJobMonitor` queries state; `IJobRuntimeStore` persists all of it. Jobs implement `IJob`: - -```csharp -public class RebuildSearchIndexJob : IJob -{ - public async Task RunAsync(JobExecutionContext context) - { - var args = context.GetArguments(); - await context.ReportProgressAsync(50, "halfway"); - return JobResult.Success; - } -} - -JobHandle handle = await jobs.EnqueueAsync(new RebuildSearchIndexArgs { Index = "orders" }); -JobState? state = await handle.GetStateAsync(); -await handle.RequestCancellationAsync(); -``` - -**Results.** `JobResult` is an immutable record: return the shared `JobResult.Success` / `JobResult.Cancelled` statics, or attach details with the `SuccessWithMessage` / `FailedWithMessage` / `CancelledWithMessage` / `FromException` factories (or a `with`-expression). - -**Typed payloads.** `EnqueueAsync(args)` serializes the arguments into the durable `JobState.Payload` with `PayloadType` stored as a discriminator; the job reads them via `JobExecutionContext.GetArguments()`, guarded by `HasArguments`. The discriminator is enforced, not just forensics: requesting a different type than the job was enqueued with throws a descriptive exception naming the stored type *before* deserialization — a structurally-similar type would otherwise deserialize into silently-wrong data. - -**Execution context.** `JobExecutionContext` carries `JobId`, `Attempt`, and the `CancellationToken`, plus the store-backed helpers useful inside job code: `ReportProgressAsync`, `RenewLeaseAsync` (heartbeat for long runs), and `IsCancellationRequestedAsync` (cooperative cancellation). Its public constructor creates a *detached* context for tests — helpers no-op, and an `arguments` object surfaces through `GetArguments` without serialization. - -**The worker.** Every run gets its own async DI scope (scoped services resolve per run, not as accidental singletons). `JobWorker` runs a bounded pool — at most `maxConcurrency` jobs in flight, a slot freeing the moment a job settles — and claims are compare-and-set guarded so concurrency cannot double-run. Lease renewal is a supervised loop, not a fire-and-forget timer: a run is cancelled when its lease is lost to another node *or* when renewal keeps failing past the lease window (the lease has lapsed on the broker's clock too, so continuing would risk double-executing side effects); the terminal state transition is ownership-guarded so a stale worker cannot overwrite the new owner's state. Stale `Processing` jobs (a worker crash mid-run) are reclaimed and re-queued while attempts remain, then dead-lettered. When hand-wiring outside DI, `JobWorker` and `JobScheduleProcessor` take an options record for their optional dependencies (`JobWorkerOptions`: time provider, node id, lease, job types, cancellation poll interval, serializer, `MaxConcurrency`; `JobScheduleProcessorOptions`: time provider, node id, transport, job types, serializer). - -### CRON scheduling - -```csharp -services.AddFoundatio() - .Jobs.UseInMemory() - .Jobs.AddCronJob("0 2 * * *", o => - { - o.MaxAttempts = 3; - o.Arguments = new ExportArgs { Format = "csv" }; - }); -``` - -`AddCronJob(cron, o => ...)` registers a `ScheduledJobDefinition`; `CronJobOptions` covers `Name`, `Scope` (`Global` = one instance per tick, `PerNode` = every instance), `Overlap` (`SkipIfRunning` default), `MisfireWindow`, `MaxAttempts` (the TOTAL number of run attempts for a failed occurrence, default 3), `TimeZone`, `Enabled`, and typed `Arguments` serialized into every occurrence's payload. An invalid cron expression or a duplicate schedule name throws at the `AddCronJob` call itself — a cron typo never becomes a job that silently never fires. Definitions are scheduled automatically when the pump starts — no manual `IScheduledJobStore.ScheduleAsync` call. The scheduler materializes every occurrence due within the misfire window (not just the latest) as durable, deduplicated store entries, and owns occurrence recovery with its own per-definition retry/dead-letter budget. - -### Managing schedules at runtime - -`IScheduledJobManager` (registered with the runtime) manages schedules while the app runs — both declaratively-registered CRON jobs and ones added on the fly share the same scheduler store: - -```csharp -var cron = provider.GetRequiredService(); - -await cron.ScheduleAsync(new ScheduledJobDefinition { // add, or replace by name - Name = "tenant-report", Cron = "0 6 * * *", JobType = typeof(TenantReportJob), - Arguments = new ReportArgs { TenantId = tenantId } }); - -await cron.RescheduleAsync("tenant-report", "0 7 * * *"); // change just the schedule -await cron.SetEnabledAsync("tenant-report", false); // pause (no occurrences materialize) -await cron.SetEnabledAsync("tenant-report", true); // resume - -JobHandle run = await cron.TriggerAsync("tenant-report"); // run NOW, independent of the cron -var state = await run.GetStateAsync(); // watch it like any durable job - -// Type-addressed overloads resolve the schedule name from the job type — the same -// default AddCronJob uses when no explicit name is given: -var schedule = await cron.GetScheduleAsync(); -await cron.SetEnabledAsync(false); -JobHandle manual = await cron.TriggerAsync(); -``` - -`TriggerAsync` materializes a durable manual occurrence (unique `"{name}:manual:…"` id, never deduplicated) that the pump claims and executes with the definition's `Arguments` and retry/dead-letter budget, returning a `JobHandle` for progress watching and cancellation. Manual runs bypass `Overlap` accounting — the trigger is a deliberate operator action — and a disabled schedule refuses to trigger (enable it first). `GetSchedulesAsync`/`GetScheduleAsync`/`UnscheduleAsync` round out the surface. - -Failures on the trigger/resolve paths are typed: addressing an unknown schedule name throws `ScheduledJobNotFoundException`, triggering a disabled schedule throws `ScheduledJobDisabledException`, and an unresolvable job type throws `JobException` — all derive from `JobException` (itself an `InvalidOperationException`, so existing catch blocks keep working). - -### The runtime pump - -`JobRuntimePumpService` is registered automatically with any runtime store, so a configured store can never silently accumulate work that nothing drains. Each poll it materializes CRON occurrences, then runs an **overlapped execution pass** — dispatching due work (message dispatches before job occurrences, so the messaging delayed-delivery fallback is never head-of-line blocked by a long job), recovering stale jobs, and running queued jobs. Scheduling keeps its cadence even while a long pass runs. Tune with `ConfigureRuntimePump`: `JobRuntimePumpOptions.Enabled` (false = manual control), `PollInterval` (1s), `BatchSize` (100), `MaxJobAttempts` (3), and `WorkerConcurrency` (1; every in-flight job still gets its own DI scope, lease, and cancellation watcher). - -## Testing - -`Foundatio.Testing` runs the real bus over a recording in-memory transport for deterministic, sleep-free tests: - -```csharp -services.AddFoundatio() - .Messaging.UseTestHarness() - .Messaging.AddHandler(); - -// start hosted services, then: -await bus.PublishAsync(new OrderPlaced(42)); -await harness.WaitForIdleAsync(); -Assert.Single(harness.Published()); -Assert.Empty(harness.DeadLetteredMessages); -``` - -Resolve `MessagingTestHarness` from the container. `WaitForIdleAsync` blocks until every destination has nothing queued and nothing in flight (throws a `TimeoutException` naming the still-busy destinations). To await one outcome without draining the whole bus, `WaitForHandledAsync(count)` returns the handled messages of `T` once enough arrive, and `WaitForDeadLetteredAsync(count)` returns the raw `RecordedMessage`s (assert `Reason`/`Attempts`); both throw a `TimeoutException` describing everything that WAS recorded. `DestinationsWithNoConsumer` lists destination keys that received sends/publishes but were never consumed — the usual reason a test is "idle immediately and Handled is empty". - -Recordings cover every movement — `SentMessages`, `PublishedMessages`, `HandledMessages`, `AbandonedMessages`, `DeadLetteredMessages`, with typed accessors `Sent()` / `Published()` / `Handled()` / `Abandoned()` / `DeadLettered()` — so the core retry/dead-letter path is directly assertable: a message redelivered N times and then dead-lettered shows up as N abandonments plus one dead-letter. - -The harness waits in **real time** (a 25ms poll cadence regardless of any injected `TimeProvider`), while delayed redeliveries execute on the injected `TimeProvider` — a test that fakes the clock must advance it itself or the retry never fires and the wait times out. For sleep-free retry tests, prefer zero backoff on the subscription instead of faking the clock: `RedeliveryBackoff = _ => TimeSpan.Zero`. - -Jobs get the same treatment: `.Jobs.UseTestHarness()` registers `JobsTestHarness`, which wraps the real in-memory job runtime with the auto pump disabled so the test decides exactly when work runs — `RunAllQueuedAsync()` runs every queued job to a settled state, `RunDueAsync(now)` performs one deterministic scheduler tick (materializes due CRON occurrences and scheduled messages, then executes them) at a fixed "now", and `RunToCompletionAsync(handle)` drives a single job to its terminal state. `Client`, `Schedules` (`IScheduledJobManager`), and `Monitor` expose the enqueue/manage/assert surface. For running an `IJob` directly without any runtime, `new JobExecutionContext(ct, arguments: myArgs)` builds a detached context — the progress/lease helpers no-op and `GetArguments()` returns the supplied object. - -## Migrating from the previous APIs - -The old implementations (`InMemoryMessageBus`, `QueueBase`/`InMemoryQueue`, `JobBase`/`QueueJobBase`/`JobWithLockBase`/`JobRunner`, `WorkItemJob`, and the hosted `AddJob`/`AddDistributedCronJob` infrastructure) were removed. The mappings: - -| Old | New | -|---|---| -| `IQueue.EnqueueAsync(item)` | `IMessageBus.SendAsync(item)` — competing consumers, ack/retry/dead-letter are core-owned | -| `IQueue.DequeueAsync` + worker loop | `AddHandler()` — the hosted handler consumes; no polling code | -| `QueueJobBase.ProcessQueueEntryAsync` | `IMessageHandler.HandleAsync(IMessageContext, ct)` | -| `IMessageBus.PublishAsync(msg, delay)` | `IMessageBus.PublishAsync(msg, new MessagePublishOptions { Delay = ... })` — delays are durable via the runtime store | -| `IMessageSubscriber.SubscribeAsync(Func)` | `SubscribeAsync((ctx, ct) => ... ctx.Message ...)`, or keep the old code compiling with `Messaging.AddLegacyAdapter()` | -| `JobBase.RunAsync(CancellationToken)` / old `IJob` | `IJob.RunAsync(JobExecutionContext)` — use `context.CancellationToken`; `JobResult` is unchanged | -| `JobWithLockBase` | The durable runtime's lease already guarantees single ownership; `AddCronJob` scope `Global` covers scheduled exclusivity | -| `WorkItemJob` + `WorkItemHandlers` | `EnqueueAsync(args)` with `context.GetArguments()` and `context.ReportProgressAsync(...)` | -| `AddDistributedCronJob(cron)` | `.Jobs.AddCronJob(cron, o => ...)` — durable occurrences with retry/dead-letter, manageable via `IScheduledJobManager` | - -**The messaging bridge**: `Messaging.AddLegacyAdapter()` registers the retained `Foundatio.Messaging.Legacy` interfaces (`IMessageBus`/`IMessagePublisher`/`IMessageSubscriber`) as a thin adapter over the new bus, so old consuming code compiles and interoperates with migrated code on the same transport. Old-style subscriptions map to per-instance, published-only subscriptions (the old fan-out semantics); `MessageOptions.UniqueId` is ignored (no broker dedup exists), and the old raw-envelope `IMessage` tap has no adapter path (the new bus is destination-scoped). Delete the `AddLegacyAdapter()` call when the last old-style call site is gone. - -## Providers - -- **In-memory** (`InMemoryMessageTransport`, `InMemoryJobRuntimeStore`) — the reference implementation for local dev and tests; supports every operation interface. -- **Redis** (`Foundatio.Redis`) — `RedisStreamsMessageTransport` (FIFO streams; delays route through the runtime store) and `RedisJobRuntimeStore`, wired via `.Messaging.UseRedis()` / `.Jobs.UseRedis()` over one shared connection. -- **AWS** (`Foundatio.Aws`) — `AwsMessageTransport` (queues on SQS, pub/sub on SNS+SQS) via `.Messaging.UseAws()`; role-aware capabilities as above, `AutoCreateDestinations` to control implicit resource creation, and LocalStack support via `ServiceUrl`. - -The transport contract is documented on the interfaces themselves (`IMessageTransport` and the `ISupports*` interfaces in `MessageTransport.cs`): settle semantics (stale/already-settled receipts SHOULD throw `ReceiptExpiredException`, but that signal is best-effort — some brokers treat stale settlement as idempotent), the per-delivery `Receipt` token (never settle by entry identity alone; a redelivery may be in flight), and the growth rule that future contract changes only ever add OPTIONAL init members to the records — an implemented transport keeps compiling. - -A new provider is validated against the shared conformance suites in `Foundatio.TestHarness`: `MessageTransportConformanceTests` (send/receive, settlement, redelivery, dead-letter, visibility, provisioning — tests skip per unimplemented operation interface) and `JobRuntimeStoreConformanceTests` (state round-trips, CAS transitions, leases, stale recovery including the renew-during-reclaim race, and scheduled-dispatch claiming, driven by a fake time provider). The messaging suite also pins the newer facts: every accepted message gets its own distinct id (batch results positionally aligned), a text content type round-trips the body, and reading the dead-letter backlog (`ReceiveDeadLetteredAsync`) consumes it — a second read returns empty. +Delivery is at least once. Stable application IDs, idempotent business operations, and transactional outbox/inbox boundaries remain application responsibilities. The runtime does not promise exactly-once side effects or distributed transactions across a business database and broker. diff --git a/docs/guide/messaging.md b/docs/guide/messaging.md index 39808fecc..158da52a0 100644 --- a/docs/guide/messaging.md +++ b/docs/guide/messaging.md @@ -1,1061 +1,135 @@ # Messaging -Messaging allows you to publish and subscribe to messages flowing through your application using pub/sub patterns.

init; } - public DateTime DeliveredAt { get; init; } -} -``` - -### Subscribe to Interface - -Subscribe to all messages implementing an interface: - -```csharp -// Receives OrderShipped, OrderDelivered, and any other IOrderEvent -await messageBus.SubscribeAsync(async orderEvent => -{ - _logger.LogInformation("Order event: {Type} for {OrderId}", - orderEvent.GetType().Name, orderEvent.OrderId); -}); ``` -### IMessage Interface - -Use the built-in `IMessage` interface for raw message access: +Each invocation gets its own dependency injection scope. A successful handler is acknowledged automatically; an exception follows the retry policy and eventually parks the message in a dead-letter destination. Use the supplied cancellation token for downstream work. ```csharp -await messageBus.SubscribeAsync(async (IMessage message, CancellationToken ct) => -{ - Console.WriteLine($"Type: {message.Type}"); - Console.WriteLine($"Correlation ID: {message.CorrelationId}"); - - // Deserialize the data - var order = message.GetBody(); -}); +await bus.SendAsync(new SendReceipt(1001)); +await bus.PublishAsync(new OrderPlaced(1001)); ``` -#### Breaking change: `IMessage.Data` is now `ReadOnlyMemory` - -`IMessage.Data` exposes the raw payload as `ReadOnlyMemory` instead of `byte[]`. This lets memory-backed transports such as Azure Service Bus and RabbitMQ expose the payload without copying it into a new array. Since it is a struct, follow these patterns: - -- Check for an empty payload with `message.Data.IsEmpty` (not `== null`) -- Read the bytes directly via `message.Data.Span` -- Call `message.Data.ToArray()` only when you need a `byte[]` - -**Buffer validity:** `Data` is only guaranteed valid for the duration of message handling. Some providers (such as RabbitMQ) expose a pooled transport buffer that is reclaimed once your handler returns, so the framework deserializes the body within the handler. If you need to retain the raw payload beyond the current handler invocation, copy it with `message.Data.ToArray()`. - -Most code that uses `GetBody()` / `Body` is unaffected. When constructing a `Message`, you can still pass a `byte[]`; it converts implicitly to `ReadOnlyMemory`. +Use `AddFoundatio().Messaging.UseInMemory()` in an API process that only produces messages. Client and storage registration never starts background execution. `AddMessagingTopology()` optionally ensures or validates declared producer destinations at host startup. -## Common Patterns +The [quickstart sample](https://github.com/FoundatioFx/Foundatio/tree/feat/messaging-jobs/samples/Foundatio.QuickstartSample) is a complete, executable host without external services. The [messaging sample](https://github.com/FoundatioFx/Foundatio/tree/feat/messaging-jobs/samples/Foundatio.MessagingSample) uses SQS/SNS and Redis jobs. -### Event-Driven Architecture +## Subscription identity -Decouple services with events: +A named subscription such as `"billing"` is durable. All replicas using that name compete for the subscription's events. A separate `"analytics"` subscription gets its own copy. Names are deployment contracts: keep them stable across restarts and class renames. Register the subscription before publishing events that it must receive; creating one does not replay earlier publications. -```csharp -// Order Service -public class OrderService -{ - private readonly IMessageBus _messageBus; - - public async Task CreateOrderAsync(CreateOrderRequest request) - { - var order = await _repository.CreateAsync(request); - - // Publish event for other services - await _messageBus.PublishAsync(new OrderCreated - { - OrderId = order.Id, - CustomerId = request.CustomerId, - CreatedAt = DateTime.UtcNow - }); - } -} - -// Inventory Service (separate process/service) -public class InventoryService -{ - public InventoryService(IMessageBus messageBus) - { - messageBus.SubscribeAsync(async order => - { - await ReserveInventoryAsync(order.OrderId); - }); - } -} - -// Notification Service (separate process/service) -public class NotificationService -{ - public NotificationService(IMessageBus messageBus) - { - messageBus.SubscribeAsync(async order => - { - await SendConfirmationEmailAsync(order.CustomerId); - }); - } -} -``` - -### Cache Invalidation +`AddSubscriber("name")` requires a nonblank durable name. Use `.Messaging.AddTemporarySubscriber()` when each running instance needs its own temporary subscription. -Coordinate cache across instances: +For dynamic `SubscribeAsync`, an unnamed subscription is temporary and receives its own copy while its listener is alive. In-memory and Redis transports support renewable two-minute subscription leases. Disposal deletes the subscription, and loss of renewal expires it after a crash. Redis physically removes expired groups during subsequent stream operations. AWS requires a named durable subscription because SQS/SNS does not provide this expiration contract; unnamed subscriptions fail explicitly. ```csharp -public class CacheInvalidationService -{ - private readonly IMessageBus _messageBus; - private readonly ICacheClient _localCache; - - public CacheInvalidationService(IMessageBus messageBus, ICacheClient localCache) - { - _messageBus = messageBus; - _localCache = localCache; - - // Listen for invalidation messages - _messageBus.SubscribeAsync(async msg => - { - await _localCache.RemoveAsync(msg.Key); - }); - } - - public async Task InvalidateAsync(string key) - { - // Remove locally - await _localCache.RemoveAsync(key); +await using var consumer = await bus.ConsumeAsync( + (context, token) => receipts.SendAsync(context.Message.OrderId, token)); - // Notify other instances - await _messageBus.PublishAsync(new CacheInvalidated { Key = key }); - } -} - -public record CacheInvalidated { public string Key { get; init; } } +await using var subscriber = await bus.SubscribeAsync( + (context, token) => billing.RecordAsync(context.Message, token), + new MessageSubscriptionOptions { Subscription = "billing" }); ``` -### Real-Time Updates - -Push updates to clients: - -```csharp -// Server-side -public class NotificationHub -{ - private readonly IMessageBus _messageBus; - - public NotificationHub(IMessageBus messageBus) - { - _messageBus = messageBus; - - // Forward bus messages to SignalR/WebSocket - _messageBus.SubscribeAsync(async notification => - { - await _hubContext.Clients - .User(notification.UserId) - .SendAsync("notification", notification); - }); - } -} +Concurrency belongs to a receiving endpoint and defaults to one. Set `MaxConcurrency` on consumer/subscription options when handlers may run concurrently. One bus rejects duplicate handlers for the same message type on the same endpoint; use separate named subscriptions when multiple event handlers each need a copy. Handlers sharing an endpoint must agree on concurrency; retry overrides belong to each registered handler. An endpoint permits at most one interface/raw fallback, avoiding ambiguous dispatch. -// When something happens -await messageBus.PublishAsync(new UserNotification -{ - UserId = "user-123", - Message = "Your order has shipped!" -}); -``` +## Receive and settle directly -### Saga/Process Manager - -Coordinate multi-step processes: +A hosted handler is optional. Direct receive returns a disposable delivery: ```csharp -public class OrderSaga +await using var delivery = await bus.ReceiveAsync(); +if (delivery is not null) { - private readonly IMessageBus _messageBus; - - public OrderSaga(IMessageBus messageBus) - { - _messageBus = messageBus; - - // Step 1: Order created -> Reserve inventory - _messageBus.SubscribeAsync(async order => - { - await ReserveInventoryAsync(order.OrderId); - await _messageBus.PublishAsync(new InventoryReserved { OrderId = order.OrderId }); - }); - - // Step 2: Inventory reserved -> Process payment - _messageBus.SubscribeAsync(async evt => - { - await ProcessPaymentAsync(evt.OrderId); - await _messageBus.PublishAsync(new PaymentProcessed { OrderId = evt.OrderId }); - }); - - // Step 3: Payment processed -> Ship order - _messageBus.SubscribeAsync(async evt => - { - await ShipOrderAsync(evt.OrderId); - }); - } + await receipts.SendAsync(delivery.Message.OrderId, delivery.CancellationToken); + await delivery.CompleteAsync(); } ``` -## Message Options +Disposing an unsettled delivery returns it for redelivery. Raw receive takes `MessageReceiveOptions` with an explicit destination. Lease renewal runs while a delivery is active. Losing the lease cancels its work; disposal, shutdown, or cancellation does not count as successful completion. -Configure message delivery: +Manual acknowledgement is available through `AckMode.Manual`. The endpoint retains its concurrency slot until settlement. Use automatic acknowledgement for ordinary handlers. -```csharp -await messageBus.PublishAsync(new OrderCreated { OrderId = 123 }, new MessageOptions -{ - // Unique message identifier - UniqueId = Guid.NewGuid().ToString(), - - // For tracing across services - CorrelationId = Activity.Current?.Id, - - // Delayed delivery - DeliveryDelay = TimeSpan.FromMinutes(5), - - // Custom properties - Properties = new Dictionary - { - ["source"] = "order-service", - ["version"] = "1.0" - } -}); -``` +## Delivery, identity, and serialization -## Delayed Message Delivery +Durable delivery is **at least once**. A worker can finish a business operation and crash before acknowledgement. Lease renewal reduces concurrent execution but cannot guarantee exactly-once side effects. In-memory state is lost when the process stops. -The `DeliveryDelay` option schedules messages for future delivery. This is useful for scenarios like: +The application `MessageId`, broker entry ID, and per-delivery receipt are distinct. Send/publish return the application ID. Supply `MessageSendOptions.MessageId` or `MessagePublishOptions.MessageId` for retry correlation and consumer deduplication; supplying an ID does not make broker sends idempotent. Scheduling, retries, and dead-lettering preserve that ID. -- **Eventual consistency** - Wait for data to propagate before processing -- **Scheduled reminders** - Send notifications after a delay -- **Retry with backoff** - Republish failed messages with increasing delays +Batch sends are not transactions. On failure, `MessageSendException.Outcomes` describes each input as accepted, unknown, or not attempted. An unknown outcome may already have reached the broker. Retrying requires an application deduplication strategy. -### Basic Usage +For long-lived contracts, register versioned wire names on producers and consumers: ```csharp -// Using MessageOptions -await messageBus.PublishAsync(new OrderReminder { OrderId = 123 }, new MessageOptions -{ - DeliveryDelay = TimeSpan.FromMinutes(30) -}); - -// Using extension method -await messageBus.PublishAsync(new OrderReminder { OrderId = 123 }, TimeSpan.FromMinutes(30)); -``` - -### Provider Support - -Different providers handle delayed delivery differently: - -| Provider | Implementation | Persistence | Survives Restart | -|----------|---------------|-------------|------------------| -| **InMemoryMessageBus** | In-memory timer | None | No | -| **AzureServiceBusMessageBus** | Native `ScheduledEnqueueTime` | Azure | Yes | -| **KafkaMessageBus** | In-memory timer | None | No | -| **RabbitMQMessageBus** | Plugin or fallback | Plugin: Yes, Fallback: No | Plugin: Yes, Fallback: No | -| **RedisMessageBus** | In-memory timer | None | No | -| **SQSMessageBus** | In-memory timer | None | No | - -### Native vs Fallback Implementation - -**Native implementations** (Azure Service Bus, RabbitMQ with plugin) persist the delayed message in the broker. The message survives application restarts and is delivered reliably. - -**Fallback implementations** hold the message in memory using a timer. This has important limitations: - -::: warning Fallback Limitations -- **Messages are lost on restart** - If your application restarts before the delay expires, the message is permanently lost -- **Messages are discarded on disposal** - During graceful shutdown, pending delayed messages are discarded -- **Best-effort delivery** - No guarantee the message will be delivered -::: - -### RabbitMQ Plugin - -RabbitMQ requires the `rabbitmq_delayed_message_exchange` plugin for native delayed delivery: - -```bash -# Enable the plugin -rabbitmq-plugins enable rabbitmq_delayed_message_exchange +builder.Services.AddFoundatio().Messaging + .AddMessageType("order-placed.v1"); ``` -The `RabbitMQMessageBus` automatically detects if the plugin is available and uses it when present. Otherwise, it falls back to the in-memory timer. - -### When to Use Delayed Delivery - -**Appropriate use cases (fallback is acceptable):** - -- Cache invalidation -- Non-critical notifications -- Eventual consistency delays (e.g., waiting for Elasticsearch to refresh) +Configure stable queue/topic routes independently of CLR class names. Concrete handlers may use the default CLR full-name discriminator; polymorphic/interface handlers accept only explicitly registered concrete types. The runtime does not scan assemblies or activate a type named by an untrusted header. Producers and consumers must agree on serialization and schema evolution. JSON uses `application/json`; other serializers default to byte-safe `application/octet-stream` unless configured otherwise. -**NOT appropriate for fallback:** +When updating a business database and publishing must commit together, persist an outbox record in the same database transaction and publish from an outbox dispatcher. Foundatio does not coordinate that transaction. Consumers should commit their deduplication record with their business changes. Scheduled dispatch send/delete and retry park/ack are also at-least-once boundaries. -- Financial transactions -- Order processing -- Any message where loss is unacceptable +## Delays and failures -For guaranteed delayed delivery, use: -- Azure Service Bus (native support) -- RabbitMQ with the delayed message plugin -- `IQueue` with `DeliveryDelay` for work items that must be processed - -## Distributed Tracing - -Foundatio automatically integrates with .NET's distributed tracing infrastructure (`System.Diagnostics.Activity`) to enable end-to-end request tracing across services. - -### Automatic CorrelationId Injection - -When you publish a message, Foundatio automatically captures the current trace context: +Native delays are used when the destination supports them. Otherwise configure an `IScheduledDispatchStore`. `AddFoundatioWorker` starts its dispatcher when both a transport and dispatch store are registered; split deployments can call `AddScheduledMessageDispatcher()` directly. Messaging depends only on that store contract; a job worker is not required. `IJobRuntimeStore` also implements the dispatch store, so a configured job store can be shared. ```csharp -// If Activity.Current exists, its ID is automatically used as CorrelationId -await messageBus.PublishAsync(new OrderCreated { OrderId = 123 }); - -// The message will have: -// - CorrelationId = Activity.Current?.Id -// - Properties["TraceState"] = Activity.Current?.TraceStateString (if present) +builder.Services.AddFoundatioWorker(foundatio => foundatio + .Messaging.UseInMemory() + .Jobs.UseInMemory()); ``` -### Manual CorrelationId +For production durability use a durable dispatch store, such as Redis. Without a suitable native delay or dispatch store, unsupported delays fail instead of being shortened. The scheduled message dispatcher runs independently of job execution. -You can also set the `CorrelationId` explicitly: +Native dead-letter transports expose `ISupportsDeadLetter`: `PeekDeadLetteredAsync` reads a bounded page without removing evidence; `DeleteDeadLetteredAsync` removes an explicit ID; `ReplayDeadLetteredAsync` sends that ID to an explicit queue/topic and resets retry metadata while preserving the application ID. Peeking repeatedly is safe. Replaying can repeat business effects, so apply the same idempotency rules as normal delivery. -```csharp -await messageBus.PublishAsync(new OrderCreated { OrderId = 123 }, new MessageOptions -{ - CorrelationId = "my-custom-correlation-id" -}); -``` - -When you provide a `CorrelationId`, the automatic injection is skipped. +If native dead-lettering is unavailable, the core sends to a fallback queue and only completes the original after that send succeeds. Failure to park the message leaves the original recoverable. AWS fallback queues support ordinary receive/settle operations, not non-destructive peek by ID. -### Trace Propagation +## Topology -When a subscriber receives a message, Foundatio: +`TopologyMode.Ensure` creates destinations on first use. `Validate` checks existing destinations and fails if missing; it does not create. `None` assumes out-of-band provisioning. This policy applies to sends, publishes, receiving, delayed dispatch, and fallback dead-letter sends. Temporary subscriptions require `Ensure`. -1. Creates a new `Activity` with the message's `CorrelationId` as the parent -2. Restores the `TraceState` from message properties -3. Adds the `CorrelationId` to the logging scope +Producer routing declares queues/topics, never phantom subscriber groups. AWS resource existence and deletion work through a fresh transport instance, including SNS bindings. Provider administration should use `ISupportsProvisioning` explicitly. -This enables distributed tracing tools (like Application Insights, Jaeger, or Zipkin) to correlate requests across services. +## Provider guarantees -### Accessing Trace Information +| Behavior | In-memory | Redis Streams | AWS SQS/SNS | +| --- | --- | --- | --- | +| Queued work and named event subscriptions | Yes, process-local | Yes | Yes | +| Temporary expiring subscriptions | Yes | Yes | Unsupported; name the subscription | +| Execution durability after process loss | No | Depends on Redis persistence/HA | Broker-managed | +| Delivery order | Initial FIFO; priority/retries can reorder | Initial FIFO; retries/concurrency can reorder | Standard queues, no ordering guarantee | +| Native delayed queue send | No | No | Up to 15 minutes | +| Native delayed publish | No | No | No | +| Lease renewal | Yes | Atomic receipt fencing | SQS visibility; stale-receipt detection is best effort | +| Non-destructive DLQ peek/replay by ID | Yes | Yes, per subscription | No; core fallback queue | +| Backlog limit | Process memory | `MaxPendingMessages`, default 100,000 per stream/DLQ | Broker limits | -In your subscriber, you can access the trace context: - -```csharp -await messageBus.SubscribeAsync(async (message, ct) => -{ - // Access correlation ID - var correlationId = message.CorrelationId; - - // Access custom properties - var traceState = message.Properties.GetValueOrDefault("TraceState"); - - // Activity.Current is automatically set with the message's trace context - _logger.LogInformation("Processing message with trace {TraceId}", Activity.Current?.TraceId); -}); -``` - -### Integration with OpenTelemetry - -Foundatio's tracing integrates seamlessly with OpenTelemetry: - -```csharp -services.AddOpenTelemetry() - .WithTracing(builder => - { - builder.AddSource(FoundatioDiagnostics.ActivitySource.Name); - // ... other configuration - }); -``` - -## Dependency Injection - -### Basic Registration - -```csharp -// In-memory (development) -services.AddSingleton(); - -// Redis (production) -services.AddSingleton(sp => -{ - var redis = sp.GetRequiredService(); - return new RedisMessageBus(o => o.Subscriber = redis.GetSubscriber()); -}); -``` - -### Subscribe at Startup - -```csharp -public class MessageSubscriber : IHostedService -{ - private readonly IMessageBus _messageBus; - private readonly IServiceProvider _services; - - public MessageSubscriber(IMessageBus messageBus, IServiceProvider services) - { - _messageBus = messageBus; - _services = services; - } - - public async Task StartAsync(CancellationToken cancellationToken) - { - await _messageBus.SubscribeAsync(async (msg, ct) => - { - using var scope = _services.CreateScope(); - var handler = scope.ServiceProvider.GetRequiredService(); - await handler.HandleAsync(msg, ct); - }, cancellationToken); - } - - public Task StopAsync(CancellationToken cancellationToken) => Task.CompletedTask; -} - -// Register -services.AddHostedService(); -``` - -## Error Handling - -### MessageBusException - -All message bus implementations throw `MessageBusException` for transport-level errors. This provides a consistent exception type regardless of the underlying provider: - -```csharp -try -{ - await messageBus.PublishAsync(new OrderCreated { OrderId = 123 }); -} -catch (MessageBusException ex) -{ - _logger.LogError(ex, "Failed to publish message: {Message}", ex.Message); - // Handle transport error (network, broker unavailable, etc.) -} -catch (OperationCanceledException) -{ - // Handle cancellation -} -``` - -**Exception Behavior:** - -| Scenario | Exception Type | Notes | -|----------|---------------|-------| -| Transport error (network, broker) | `MessageBusException` | Wraps underlying exception | -| Null message/type | `ArgumentNullException` | Thrown immediately | -| Cancellation requested | `OperationCanceledException` | Passed through unchanged | -| Serialization error | `MessageBusException` | Wraps serialization exception | - -### Subscriber Error Handling - -**Important:** Subscriber errors do NOT propagate to the publisher. This behavior is consistent across ALL implementations, including `InMemoryMessageBus`. This design ensures: - -1. **Consistent behavior** - Code that works with `InMemoryMessageBus` in tests will behave the same with distributed buses in production -2. **Matches distributed reality** - In distributed systems, publishers and subscribers run in separate processes; publisher cannot see subscriber errors -3. **Predictable error handling** - Subscribers are responsible for handling their own errors - -```csharp -// Publisher - will NOT see subscriber errors -await messageBus.PublishAsync(new OrderCreated { OrderId = 123 }); -// Returns successfully even if a subscriber throws - -// Subscriber - handle your own errors -await messageBus.SubscribeAsync(async order => -{ - try - { - await ProcessOrderAsync(order); - } - catch (Exception ex) - { - _logger.LogError(ex, "Failed to process order {OrderId}", order.OrderId); - // Optionally publish failure event, retry, etc. - } -}); -``` - -### Provider Behavior Summary - -| Provider | Publish Errors | Subscriber Errors | Redelivery on Failure | -|----------|---------------|-------------------|----------------------| -| **InMemoryMessageBus** | Throws `MessageBusException` | Logged, swallowed | No | -| **AzureServiceBusMessageBus** | Throws `MessageBusException` | Logged, SDK handles | Yes (`MaxDeliveryCount`) | -| **KafkaMessageBus** | Fire-and-forget with callback | Logged, offset not committed | Yes (redelivered) | -| **RabbitMQMessageBus** | Throws `MessageBusException` | Logged, nack/requeue | Yes (`DeliveryLimit`) | -| **RedisMessageBus** | Throws `MessageBusException` | Logged, swallowed | No (pub/sub has no ack) | -| **SQSMessageBus** | Throws `MessageBusException` | Logged, message not deleted | Yes (redelivered) | - -::: tip Logging -All errors are logged at `Error` level. Subscriber errors are logged exactly once by the base class. -::: - -### In Subscribers - -```csharp -await messageBus.SubscribeAsync(async order => -{ - try - { - await ProcessOrderAsync(order); - } - catch (Exception ex) - { - _logger.LogError(ex, "Failed to process order {OrderId}", order.OrderId); - - // Optionally publish failure event - await _messageBus.PublishAsync(new OrderProcessingFailed - { - OrderId = order.OrderId, - Error = ex.Message - }); - } -}); -``` - -### With Retry - -```csharp -await messageBus.SubscribeAsync(async order => -{ - await _resiliencePolicy.ExecuteAsync(async ct => - { - await ProcessOrderAsync(order, ct); - }); -}); -``` - -## Cancellation Token Behavior - -Understanding how cancellation tokens are handled internally is important for building reliable publishers and subscribers. - -### Resource Creation Uses Disposal Token - -When you call `PublishAsync` or `SubscribeAsync`, the message bus may need to create infrastructure (e.g., Azure Service Bus topics, RabbitMQ exchanges, SQS topics). These setup operations use an internal disposal token — **not** the caller's cancellation token. This means: - -- **Topic and subscription creation only abort when the message bus is disposed**, never because a single caller cancelled their operation. -- A cancelled publish will not leave topic infrastructure in a half-created state. -- Multiple concurrent publishers/subscribers cannot interfere with each other's setup. - -### Linked Cancellation for Publish - -The caller's cancellation token is combined with the disposal token into a linked token for the actual publish operation. This means: - -- Publish cancels when **either** the caller cancels **or** the message bus is disposed. -- Graceful shutdown via `Dispose()` cancels all in-flight publishes promptly. - -```csharp -// Topic creation always completes (unless disposed), even if the publish is cancelled -using var cts = new CancellationTokenSource(TimeSpan.FromSeconds(5)); -await messageBus.PublishAsync(new OrderCreated { OrderId = 123 }, cancellationToken: cts.Token); -``` - -### For Implementation Authors - -If you are writing a custom `IMessageBus` implementation by extending `MessageBusBase`: - -- **`EnsureTopicCreatedAsync`** always receives `DisposedCancellationToken`. Use it for all setup operations (lock acquisition, API calls, etc.). -- **`EnsureTopicSubscriptionAsync`** always receives `DisposedCancellationToken`. Use it for subscription infrastructure setup. -- **`PublishImplAsync`** receives a linked token (caller + disposal). Respect it for the actual message send. - -## Best Practices - -### 1. Use Immutable Messages - -```csharp -// ✅ Good: Immutable record -public record OrderCreated -{ - public int OrderId { get; init; } - public required string CustomerId { get; init; } -} - -// ❌ Bad: Mutable class -public class OrderCreated -{ - public int OrderId { get; set; } - public string CustomerId { get; set; } -} -``` - -### 2. Include Timestamp and Correlation - -```csharp -public record OrderCreated -{ - public int OrderId { get; init; } - public DateTime OccurredAt { get; init; } = DateTime.UtcNow; - public string CorrelationId { get; init; } = Activity.Current?.Id; -} -``` - -### 3. Handle Idempotency - -```csharp -await messageBus.SubscribeAsync(async order => -{ - // Check if already processed - if (await _processedEvents.ContainsAsync(order.EventId)) - { - _logger.LogDebug("Already processed {EventId}", order.EventId); - return; - } - - await ProcessOrderAsync(order); - await _processedEvents.AddAsync(order.EventId); -}); -``` - -### 4. Use Specific Message Types - -```csharp -// ✅ Good: Specific, intentional messages -public record OrderCreated { ... } -public record OrderShipped { ... } -public record OrderCancelled { ... } - -// ❌ Bad: Generic, multi-purpose messages -public record OrderEvent { public string Action { get; set; } } -``` - -### 5. Keep Messages Small - -Messages should contain identifiers and essential data only, not full entity payloads. - -```csharp -// ✅ Good: Just identifiers -public record OrderCreated -{ - public int OrderId { get; init; } -} - -// ❌ Bad: Full entity in message -public record OrderCreated -{ - public Order FullOrderWithAllDetails { get; init; } -} -``` - -## Message Size Limits - -Different message bus implementations have different size limits. Understanding these limits is essential for reliable messaging. - -| Provider | Max Message Size | Notes | -|----------|------------------|-------| -| InMemoryMessageBus | Limited by available memory | No practical limit | -| AzureServiceBusMessageBus | 256 KB (Standard) / 100 MB (Premium) | Use claim check for large payloads | -| KafkaMessageBus | 1 MB (default) | Configurable via `message.max.bytes` | -| RabbitMQMessageBus | 128 MB (default) | Configurable, but keep small | -| RedisMessageBus | 512 MB (Redis limit) | Recommended: < 1 MB for performance | -| SQSMessageBus | 256 KB | Use claim check for large payloads | - -### Claim Check Pattern for Large Payloads - -For large data, store it externally and pass a reference (also known as the Claim Check Pattern): - -```csharp -// Instead of embedding large data -public record DocumentProcessed -{ - public string DocumentId { get; init; } - public string BlobPath { get; init; } // Reference to storage - public long SizeBytes { get; init; } -} - -// Subscriber retrieves from storage -await messageBus.SubscribeAsync(async msg => -{ - var document = await _fileStorage.GetObjectAsync(msg.BlobPath); - await ProcessDocumentAsync(document); -}); -``` - -## Notification Patterns - -### Real-Time Notifications with SignalR - -```csharp -public class NotificationService : IHostedService -{ - private readonly IMessageBus _messageBus; - private readonly IHubContext _hubContext; - - public NotificationService(IMessageBus messageBus, IHubContext hubContext) - { - _messageBus = messageBus; - _hubContext = hubContext; - } - - public async Task StartAsync(CancellationToken ct) - { - // Bridge message bus to SignalR - await _messageBus.SubscribeAsync(async (msg, ct) => - { - await _hubContext.Clients - .User(msg.UserId) - .SendAsync("Notification", msg.Title, msg.Body, ct); - }, ct); - - // Broadcast to all users - await _messageBus.SubscribeAsync(async (msg, ct) => - { - await _hubContext.Clients.All - .SendAsync("Announcement", msg.Message, ct); - }, ct); - } - - public Task StopAsync(CancellationToken ct) => Task.CompletedTask; -} -``` - -### Delayed Notifications - -```csharp -// Schedule a reminder -await messageBus.PublishAsync(new ReminderNotification -{ - UserId = "user-123", - Message = "Don't forget to complete your order!" -}, new MessageOptions -{ - DeliveryDelay = TimeSpan.FromHours(24) -}); -``` - -### Fan-Out Pattern - -Publish once, process in multiple ways: - -```csharp -// Single publish -await messageBus.PublishAsync(new OrderCreated { OrderId = 123 }); - -// Multiple subscribers handle different concerns -await messageBus.SubscribeAsync(async order => -{ - await _emailService.SendConfirmationAsync(order.OrderId); -}); - -await messageBus.SubscribeAsync(async order => -{ - await _inventoryService.ReserveAsync(order.OrderId); -}); - -await messageBus.SubscribeAsync(async order => -{ - await _analyticsService.TrackAsync("order_created", order.OrderId); -}); -``` - -## Resource Management - -### Disposal Lifecycle - -Message buses implement both `IDisposable` and `IAsyncDisposable`. Prefer `await using` (or `DisposeAsync()`) for clean shutdown: - -```csharp -// Preferred: async disposal -await using var messageBus = new InMemoryMessageBus(); -await messageBus.SubscribeAsync(async e => { /* ... */ }); -// DisposeAsync is called when scope ends - -// DI container manages lifetime automatically -services.AddSingleton(); -``` - -Disposal follows a **two-phase** sequence to prevent message loss in durable providers: - -1. **Graceful drain** — In-flight handlers finish executing while subscribers and the internal cancellation token are still active. Providers that support processor-level draining (e.g., Azure Service Bus `StopProcessingAsync`) execute it here via `ShutdownAsync`. -2. **Teardown** — The internal cancellation token is cancelled, all subscribers are cleared, and transport infrastructure (connections, channels, clients) is closed and disposed via `CleanupAsync`. - -> **Note:** The base `MessageBusBase` implementation does not guarantee that all active subscriber callbacks have completed before `DisposeAsync` returns. Provider-specific draining behavior (such as Azure Service Bus `StopProcessingAsync`) is implemented in provider overrides of `ShutdownAsync`. - -### Message Durability During Shutdown - -What happens to messages that arrive while the bus is disposing depends on the provider: - -| Provider | In-Flight Messages | Arriving During Dispose | After Dispose | -|---|---|---|---| -| **InMemoryMessageBus** | Completed normally | Dropped (no persistence) | Lost | -| **AzureServiceBusMessageBus** | Completed; abandoned if bus disposes mid-handler (PeekLock) | Remain in topic for other subscribers | Persisted in Azure | -| **KafkaMessageBus** | Completed; offset not committed if bus disposes mid-handler | Remain in partition (uncommitted offset) | Persisted in Kafka | -| **RabbitMQMessageBus** | Completed; requeued if bus disposes mid-handler | Remain in queue | Persisted in RabbitMQ | -| **RedisMessageBus** | Completed normally | Dropped (pub/sub has no persistence) | Lost | -| **SQSMessageBus** | Completed; message not deleted if bus disposes mid-handler | Remain in SQS queue | Persisted in SQS | - -::: tip Fire-and-Forget Providers -`InMemoryMessageBus` and `RedisMessageBus` use fire-and-forget delivery. Messages that arrive when no subscriber is listening are permanently lost. This is by design — if you need guaranteed delivery, use a durable provider or `IQueue`. -::: - -### Writing Custom Providers - -If you are extending `MessageBusBase` with a custom provider, override the lifecycle hooks: - -- **`ShutdownAsync()`** — Called *before* the cancellation token is cancelled and *before* subscribers are cleared. Use this to gracefully drain your transport (e.g., stop a processor, close a consumer group). Subscribers are still active and can finish processing. -- **`CleanupAsync()`** — Called *after* the cancellation token is cancelled and *after* subscribers are cleared. Use this to tear down transport infrastructure (close connections, dispose clients, await background tasks). - -```csharp -public class MyMessageBus : MessageBusBase -{ - // Phase 1: Stop accepting new messages, drain in-flight work. - // When the body is a single call, return the Task directly (no extra async state machine). - protected override Task ShutdownAsync() => _processor.StopAsync(); - - protected override async Task CleanupAsync() - { - // Phase 2: Close connections, dispose clients — ConfigureAwait(false) in library overrides - await _connection.CloseAsync().ConfigureAwait(false); - _client.Dispose(); - } -} -``` +Redis capacity rejects new messages instead of trimming unread or pending entries. A slow durable subscription therefore applies backpressure to the topic. Acknowledged topic entries are trimmed only when every subscription has progressed past them. Delete abandoned durable subscriptions deliberately; temporary leases are not a replacement for durable subscription administration. -If `ShutdownAsync` needs multiple steps, use `async`/`await` and apply `.ConfigureAwait(false)` to each await (within Foundatio provider projects, the same pattern uses the internal `AnyContext()` helper). +SQS/SNS support varies by destination role. Do not infer topic capabilities from queue capabilities. The shared conformance suite exercises in-memory, Redis, and SQS/SNS via LocalStack in CI; the emulator is not evidence of a live AWS deployment. -## Next Steps +## Migration -- [Queues](./queues) - For guaranteed delivery with acknowledgment -- [Caching](./caching) - Cache invalidation with messaging -- [Jobs](./jobs) - Background processing triggered by messages +The former publish-only interfaces live under `Foundatio.Messaging.Legacy`; `Messaging.AddLegacyAdapter()` adapts them to this bus. Legacy `IQueue` workers migrate to an explicit consumer and `SendAsync`. There is no `Deliveries.Both`, handler-name-derived subscriber identity, or `PerInstance` flag. Choose `AddConsumer` or `AddSubscriber`, and give durable subscribers explicit names. diff --git a/docs/guide/nullable-reference-types.md b/docs/guide/nullable-reference-types.md index 33f3c7577..fcb3aab10 100644 --- a/docs/guide/nullable-reference-types.md +++ b/docs/guide/nullable-reference-types.md @@ -1,5 +1,8 @@ # Nullable Reference Types (NRT) Migration +This migration reference includes earlier queue/job interfaces removed by the unreleased redesign.

For manual processing, call `RenewLockAsync()` periodically within your processing logic. -::: - -**Best practices for `WorkItemTimeout`:** - -- Set `WorkItemTimeout` to your typical processing time plus padding (e.g., 2x normal duration) -- Call `RenewLockAsync()` before the timeout expires if processing takes longer than expected -- Monitor your processing times to adjust the timeout appropriately - -#### Manual Renewal in Queue Jobs - -For long-running operations in a `QueueJobBase`, renew the lock during processing: - -```csharp -public class VideoProcessorJob : QueueJobBase -{ - private readonly IVideoService _videoService; - - public VideoProcessorJob(IQueue queue, IVideoService videoService) - : base(queue) => _videoService = videoService; - - protected override async Task ProcessQueueEntryAsync( - QueueEntryContext context) - { - var workItem = context.QueueEntry.Value; - var startTime = DateTime.UtcNow; - - try - { - // Start processing - await _videoService.StartProcessingAsync(workItem.VideoId); - - // Renew lock if processing is taking longer than expected - if (DateTime.UtcNow - startTime > TimeSpan.FromMinutes(3)) - { - await context.QueueEntry.RenewLockAsync(); - } - - await _videoService.CompleteProcessingAsync(workItem.VideoId); - return JobResult.Success; - } - catch (Exception ex) - { - return JobResult.FromException(ex); - } - } -} -``` - -::: warning Manual Lock Renewal -Most processing should complete within the `WorkItemTimeout`. If you regularly need lock renewal, increase the `WorkItemTimeout` instead. Manual renewal should only be used for truly variable-duration workloads where you cannot predict processing time accurately. -::: - -#### Ensuring Single Processing with GetQueueEntryLockAsync - -Override `GetQueueEntryLockAsync` to acquire a distributed lock based on a unique value from the work item. This guarantees that even if the same item is enqueued multiple times (e.g., due to retries or system failures), only one instance will process it at a time. - -**When to use this:** - -- Processing must be guaranteed to occur only once per unique identifier -- Work items can be re-queued due to failures, but duplicate processing would cause issues -- You need to lock on a business key (e.g., user ID, order ID) rather than the queue entry ID - -```csharp -public class OrderProcessorJob : QueueJobBase -{ - private readonly ILockProvider _lockProvider; - private readonly IOrderService _orderService; - - public OrderProcessorJob( - IQueue queue, - ILockProvider lockProvider, - IOrderService orderService) : base(queue) - { - _lockProvider = lockProvider; - _orderService = orderService; - } - - // Override to lock on the order ID instead of the queue entry ID - protected override Task GetQueueEntryLockAsync( - IQueueEntry queueEntry, - CancellationToken cancellationToken = default) - { - // Lock on the business key (order ID) to prevent concurrent processing - // of the same order across all queue entries - string lockKey = $"order:{queueEntry.Value.OrderId}"; - return _lockProvider.TryAcquireAsync(lockKey, TimeSpan.FromMinutes(5), cancellationToken); - } - - protected override async Task ProcessQueueEntryAsync( - QueueEntryContext context) - { - // This will only execute if we successfully acquired the lock - // Multiple queue entries for the same order will be serialized - var orderId = context.QueueEntry.Value.OrderId; - - await _orderService.ProcessAsync(orderId, context.CancellationToken); - return JobResult.Success; - } -} -``` - -**How it works:** - -1. When `QueueJobBase` dequeues an entry, it calls `GetQueueEntryLockAsync` before processing -2. If the lock cannot be acquired (returns `null`), the entry is abandoned and returned to the queue -3. If the lock acquisition throws an exception (e.g., network failure), the entry is abandoned and a `JobResult.FromException` is returned -4. If the lock is acquired, processing continues and the lock is automatically released after completion -5. The lock is also used for manual renewal within `ProcessQueueEntryAsync` via `await context.QueueEntry.RenewLockAsync()` - -::: tip Lock Provider Selection -Use a distributed lock provider (e.g., `CacheLockProvider` with Redis) in production to coordinate across multiple instances. For single-instance scenarios, `CacheLockProvider` with `InMemoryCacheClient` is sufficient. -::: - -## Processing Patterns - -::: tip Recommended Approach -For production applications, use `QueueJobBase` with `Foundatio.Extensions.Hosting` for reliable, automatic background processing. See [Jobs - Queue Processor Jobs](/guide/jobs#queue-processor-jobs) for details. The patterns below are for advanced scenarios or custom integrations. -::: - -### Simple Processing Loop - -```csharp -while (!cancellationToken.IsCancellationRequested) -{ - var entry = await queue.DequeueAsync(cancellationToken); - if (entry == null) - continue; - - try - { - await ProcessAsync(entry.Value); - await entry.CompleteAsync(); - } - catch (Exception ex) - { - _logger.LogError(ex, "Failed to process {Id}", entry.Value.Id); - await entry.AbandonAsync(); - } -} -``` - -### Using StartWorkingAsync - -Simplified background processing: - -```csharp -// Start processing in background -await queue.StartWorkingAsync( - async (entry, ct) => - { - await ProcessAsync(entry.Value); - }, - autoComplete: true, // Automatically complete on success - cancellationToken -); -``` - -## Queue Entry Options - -Configure enqueue behavior: - -```csharp -await queue.EnqueueAsync(new WorkItem { Id = 1 }, new QueueEntryOptions -{ - UniqueId = "unique-id", // Dedupe by ID - CorrelationId = "request-123", // For tracing - DeliveryDelay = TimeSpan.FromMinutes(5), // Delayed delivery - Properties = new Dictionary - { - ["priority"] = "high" - } -}); -``` - -## Queue Events - -Subscribe to queue lifecycle events: - -```csharp -var queue = new InMemoryQueue(); - -queue.Enqueuing.AddHandler((sender, args) => -{ - _logger.LogInformation("Enqueuing: {Data}", args.Data); - return Task.CompletedTask; -}); - -queue.Enqueued.AddHandler((sender, args) => -{ - _logger.LogInformation("Enqueued: {Id}", args.Entry.Id); - return Task.CompletedTask; -}); - -queue.Dequeued.AddHandler((sender, args) => -{ - _logger.LogInformation("Dequeued: {Id}", args.Entry.Id); - return Task.CompletedTask; -}); - -queue.Completed.AddHandler((sender, args) => -{ - _logger.LogInformation("Completed: {Id}", args.Entry.Id); - return Task.CompletedTask; -}); - -queue.Abandoned.AddHandler((sender, args) => -{ - _logger.LogWarning("Abandoned: {Id}", args.Entry.Id); - return Task.CompletedTask; -}); - -queue.QueueDeleted.AddHandler((sender, args) => -{ - _logger.LogInformation("Queue deleted"); - return Task.CompletedTask; -}); -``` - -## Queue Behaviors - -Extend queue functionality with behaviors. Behaviors hook into queue events to add cross-cutting concerns like logging, metrics, or deduplication. - -### Creating Custom Behaviors - -```csharp -public class LoggingQueueBehavior : QueueBehaviorBase where T : class -{ - private readonly ILogger _logger; - - public LoggingQueueBehavior(ILogger logger) => _logger = logger; - - protected override Task OnEnqueued(object sender, EnqueuedEventArgs args) - { - _logger.LogInformation("Enqueued {Id}", args.Entry.Id); - return Task.CompletedTask; - } - - protected override Task OnDequeued(object sender, DequeuedEventArgs args) - { - _logger.LogInformation("Dequeued {Id}", args.Entry.Id); - return Task.CompletedTask; - } - - protected override Task OnCompleted(object sender, CompletedEventArgs args) - { - _logger.LogInformation("Completed {Id} in {Duration}ms", - args.Entry.Id, args.Entry.ProcessingTime.TotalMilliseconds); - return Task.CompletedTask; - } - - protected override Task OnAbandoned(object sender, AbandonedEventArgs args) - { - _logger.LogWarning("Abandoned {Id}, attempt {Attempt}", - args.Entry.Id, args.Entry.Attempts); - return Task.CompletedTask; - } - - protected override Task OnQueueDeleted(object sender, QueueDeletedEventArgs args) - { - _logger.LogInformation("Queue deleted"); - return Task.CompletedTask; - } -} - -// Attach to queue -queue.AttachBehavior(new LoggingQueueBehavior(logger)); -``` - -### Built-in: Duplicate Detection Behavior - -Foundatio includes `DuplicateDetectionQueueBehavior` to prevent duplicate messages from being enqueued. This is useful for scenarios where the same work item might be submitted multiple times. - -```csharp -// Your message must implement IHaveUniqueIdentifier -public class OrderWorkItem : IHaveUniqueIdentifier -{ - public int OrderId { get; set; } - public string UniqueIdentifier => $"order:{OrderId}"; -} - -// Attach the behavior -var cache = new InMemoryCacheClient(); -queue.AttachBehavior(new DuplicateDetectionQueueBehavior( - cache, - loggerFactory, - detectionWindow: TimeSpan.FromMinutes(10) // How long to remember seen IDs -)); - -// Duplicates are automatically discarded -await queue.EnqueueAsync(new OrderWorkItem { OrderId = 123 }); // ✅ Enqueued -await queue.EnqueueAsync(new OrderWorkItem { OrderId = 123 }); // ❌ Discarded (duplicate) -await queue.EnqueueAsync(new OrderWorkItem { OrderId = 456 }); // ✅ Enqueued -``` - -**How it works:** - -1. On enqueue, the behavior checks if the `UniqueIdentifier` exists in the cache -2. If found, the message is discarded (not enqueued) -3. If not found, the identifier is cached with the specified TTL -4. On dequeue, the identifier is removed from the cache (allowing re-submission) - -### Behavior Attachment Rules - -Each behavior instance can only be attached to a single queue. Attempting to attach the same behavior instance to multiple queues or attaching it twice to the same queue throws a `QueueException`. This prevents subtle bugs where event handlers could fire against the wrong queue reference. - -```csharp -// ✅ Correct: separate instances for each queue -queue1.AttachBehavior(new LoggingQueueBehavior(logger)); -queue2.AttachBehavior(new LoggingQueueBehavior(logger)); - -// ❌ Throws QueueException: same instance attached twice -var behavior = new LoggingQueueBehavior(logger); -queue1.AttachBehavior(behavior); -queue2.AttachBehavior(behavior); // throws QueueException -``` - -### Attaching Multiple Behaviors - -You can attach multiple different behavior instances to a single queue: - -```csharp -var queue = new InMemoryQueue(o => o - .Behaviors( - new LoggingQueueBehavior(logger), - new DuplicateDetectionQueueBehavior(cache, loggerFactory), - new MetricsQueueBehavior(metrics) - )); -``` - -## Queue Statistics - -Monitor queue health: - -```csharp -var stats = await queue.GetQueueStatsAsync(); - -Console.WriteLine($"Queued: {stats.Queued}"); -Console.WriteLine($"Working: {stats.Working}"); -Console.WriteLine($"Dead Letter: {stats.Deadletter}"); -Console.WriteLine($"Enqueued: {stats.Enqueued}"); -Console.WriteLine($"Dequeued: {stats.Dequeued}"); -Console.WriteLine($"Completed: {stats.Completed}"); -Console.WriteLine($"Abandoned: {stats.Abandoned}"); -Console.WriteLine($"Errors: {stats.Errors}"); -Console.WriteLine($"Timeouts: {stats.Timeouts}"); -``` - -## Dead Letter Queue - -Handle failed messages that have exceeded the retry limit: - -```csharp -// Get dead letter items -var deadLetters = await queue.GetDeadletterItemsAsync(); - -foreach (var item in deadLetters) -{ - _logger.LogWarning("Dead letter: {Id}", item.Id); - - // Optionally re-queue for retry - await queue.EnqueueAsync(item); -} -``` - -### When Messages Go to Dead Letter - -Messages are moved to the dead letter queue when: - -1. The message has been abandoned more times than the configured `Retries` count -2. Processing repeatedly fails and the retry limit is exhausted - -### Monitoring Dead Letters - -```csharp -var stats = await queue.GetQueueStatsAsync(); -if (stats.Deadletter > 0) -{ - _logger.LogWarning("Dead letter queue has {Count} items", stats.Deadletter); - // Alert operations team, trigger investigation -} -``` - -### Poison Message Handling - -When a message cannot be deserialized during dequeue (e.g., corrupted data, schema changes, or serializer misconfiguration), all Foundatio queue implementations handle it gracefully: - -1. **The deserialization exception is caught** and logged as a warning with the message ID and current attempt count -2. **The message is abandoned** through the normal `AbandonAsync` flow, which increments the attempt counter and applies retry delay/backoff -3. **`null` is returned** from `DequeueAsync`, so the consumer never sees the undeserializable message -4. **After exhausting retries**, the message is moved to the dead letter queue through the standard dead-lettering path - -This approach gives operators a window to fix transient issues (such as a missing `JsonConverter` or incorrect serializer configuration) before messages are permanently dead-lettered. If the serializer configuration is corrected and redeployed before retries are exhausted, the message will deserialize successfully on the next attempt. - -```text -Dequeue → Deserialize fails → Abandon (attempt incremented) - → Still has retries? → Re-queued with backoff delay - → Retries exhausted? → Moved to dead letter queue -``` - -## Retry Policies - -All Foundatio queue implementations share common retry behavior configured via `SharedQueueOptions`: - -| Option | Default | Description | -|--------|---------|-------------| -| `Retries` | 2 | Maximum number of retry attempts before dead-lettering | -| `WorkItemTimeout` | 5 minutes | How long a worker can hold a message before it's considered abandoned | - -### WorkItemTimeout Best Practices - -The `WorkItemTimeout` determines how long a dequeued entry stays locked before being considered abandoned and returned to the queue for retry. Setting this value correctly is critical for reliable queue processing. - -**Guidelines for setting `WorkItemTimeout`:** - -```csharp -var queue = new RedisQueue(o => -{ - // For predictable workloads: typical duration + padding - // Example: If processing takes 2 minutes, set to 4-5 minutes - o.WorkItemTimeout = TimeSpan.FromMinutes(5); - - // For variable workloads: maximum expected duration + buffer - // Example: If processing can take up to 10 minutes, set to 15 minutes - o.WorkItemTimeout = TimeSpan.FromMinutes(15); -}); -``` - -**Sizing recommendations:** - -- **Fast operations (< 30 seconds)**: Set to 1-2 minutes to allow for retries without long delays -- **Standard operations (1-5 minutes)**: Set to 2x your average processing time (e.g., 3 minutes avg → 6 minute timeout) -- **Long operations (> 5 minutes)**: Set to 1.5x your maximum expected time, but consider using manual lock renewal if highly variable -- **Always include padding**: Account for network latency, temporary slowdowns, and system load - -**What happens when timeout expires:** - -1. The queue entry lock is released -2. Another worker can pick up the same entry -3. The original worker may still be processing (potentially duplicate work) -4. Entry's `Attempts` counter increments -5. After `Retries` attempts, the entry moves to the dead letter queue - -::: warning Timeout Too Short -If `WorkItemTimeout` is too short, entries will be re-queued before processing completes, leading to duplicate processing attempts and wasted resources. -::: - -::: tip Monitoring and Adjustment -Monitor your queue processing times and adjust `WorkItemTimeout` based on actual metrics. Use Application Insights, logging, or custom telemetry to track processing duration over time. -::: - -### InMemoryQueue Retry Options - -The in-memory queue provides additional retry configuration: - -```csharp -var queue = new InMemoryQueue(o => -{ - o.Retries = 3; // Max retry attempts - o.RetryDelay = TimeSpan.FromMinutes(1); // Base delay between retries - o.RetryMultipliers = new[] { 1, 3, 5, 10 }; // Exponential backoff multipliers -}); -``` - -**Retry delay calculation:** `RetryDelay × RetryMultipliers[attempt - 1]` - -For example, with defaults: - -- 1st retry: 1 minute × 1 = 1 minute -- 2nd retry: 1 minute × 3 = 3 minutes -- 3rd retry: 1 minute × 5 = 5 minutes -- 4th+ retry: 1 minute × 10 = 10 minutes - -### Provider-Specific Retry Behavior - -| Provider | Retry Mechanism | Dead Letter Support | -|----------|-----------------|---------------------| -| InMemoryQueue | Built-in with configurable backoff | In-memory dead letter queue | -| RedisQueue | Built-in with configurable backoff | Redis-backed dead letter queue | -| AzureServiceBusQueue | Native Service Bus retries | Native DLQ with message metadata | -| AzureStorageQueue | Built-in retries | Poison message queue | -| SQSQueue | Native SQS retries | Native DLQ (requires configuration) | - -## Message Size Limits - -Different queue providers have different message size limits. Understanding these limits is crucial for designing your message contracts. - -| Provider | Max Message Size | Notes | -|----------|------------------|-------| -| InMemoryQueue | Limited by available memory | No practical limit | -| RedisQueue | 512 MB (Redis limit) | Recommended: < 1 MB for performance | -| AzureServiceBusQueue | 256 KB (Standard) / 100 MB (Premium) | Use claim check pattern for large payloads | -| AzureStorageQueue | 64 KB | Base64 encoded, effective ~48 KB | -| SQSQueue | 256 KB | Use S3 for larger messages | - -### Best Practice: Keep Messages Small - -```csharp -// ✅ Good: Small message with reference -public record ProcessImageWorkItem -{ - public required string ImageBlobPath { get; init; } // Reference to storage - public required string OutputPath { get; init; } - public required ImageProcessingOptions Options { get; init; } -} - -// ❌ Bad: Large payload in message -public record ProcessImageWorkItem -{ - public required byte[] ImageData { get; init; } // Could be megabytes! - public required ImageProcessingOptions Options { get; init; } -} -``` - -### Claim Check Pattern for Large Payloads - -When you need to process large data, store it externally and pass a reference: - -```csharp -// Store large data in blob storage -var blobPath = $"work-items/{Guid.NewGuid()}.json"; -await fileStorage.SaveObjectAsync(blobPath, largePayload); - -// Enqueue reference only -await queue.EnqueueAsync(new WorkItem -{ - PayloadPath = blobPath, - PayloadSize = largePayload.Length -}); - -// In worker: retrieve the payload -var entry = await queue.DequeueAsync(); -var payload = await fileStorage.GetObjectAsync(entry.Value.PayloadPath); -await ProcessAsync(payload); -await entry.CompleteAsync(); - -// Clean up blob after processing -await fileStorage.DeleteFileAsync(entry.Value.PayloadPath); -``` - -## Dependency Injection - -### Basic Registration - -```csharp -// In-memory (development) -services.AddSingleton>(sp => - new InMemoryQueue()); - -// Redis (production) -services.AddSingleton>(sp => - new RedisQueue(o => { - o.ConnectionMultiplexer = sp.GetRequiredService(); - o.Name = "work-items"; - })); -``` - -::: tip Automatic Queue Processing -For automatic background processing of queue items, use `QueueJobBase` with `Foundatio.Extensions.Hosting`. See [Jobs - Queue Processor Jobs](/guide/jobs#queue-processor-jobs) for details. - -```csharp -// Register queue and processor job -services.AddSingleton>(sp => new InMemoryQueue()); -services.AddJob(); // Automatically processes queue items -``` - -### Multiple Queues - -```csharp -services.AddSingleton>(sp => - new InMemoryQueue(o => o.Name = "orders")); - -services.AddSingleton>(sp => - new InMemoryQueue(o => o.Name = "emails")); -``` - -## Queue Exceptions - -Queue operations throw `QueueException` for queue-specific error conditions. This provides a consistent, predictable exception type across all queue implementations (in-memory, Redis, Azure, AWS, etc.). - -```csharp -using Foundatio.Queues; - -try -{ - // Attempting to reuse a behavior instance throws QueueException - var behavior = new LoggingQueueBehavior(logger); - queue1.AttachBehavior(behavior); - queue2.AttachBehavior(behavior); // throws QueueException -} -catch (QueueException ex) -{ - logger.LogError(ex, "Queue operation failed: {Message}", ex.Message); -} -``` - -## Cancellation Token Behavior - -Understanding how cancellation tokens are handled internally is important for building reliable queue consumers. - -### Resource Creation Uses Disposal Token - -When you call `EnqueueAsync`, `DequeueAsync`, or `GetDeadletterItemsAsync`, the queue may need to create infrastructure (e.g., SQS queues, Azure Service Bus queues, Redis streams). These setup operations use an internal disposal token — **not** the caller's cancellation token. This means: - -- **Queue creation only aborts when the queue is disposed**, never because a single caller cancelled their operation. -- A cancelled `DequeueAsync` call (e.g., from a zero timeout) will not prevent queue creation from completing. -- Multiple concurrent callers cannot interfere with each other's setup. - -### Linked Cancellation for Operations - -The caller's cancellation token is combined with the disposal token into a linked token for the actual operation (dequeue, deadletter retrieval, etc.). This means: - -- Operations cancel when **either** the caller cancels **or** the queue is disposed. -- Graceful shutdown via `Dispose()` cancels all in-flight operations promptly. - -```csharp -// This will never prevent queue creation, even though it times out immediately -var entry = await queue.DequeueAsync(TimeSpan.Zero); - -// The cancellation token only affects the dequeue wait, not infrastructure setup -using var cts = new CancellationTokenSource(TimeSpan.FromSeconds(5)); -var entry = await queue.DequeueAsync(cts.Token); -``` - -### For Implementation Authors - -If you are writing a custom `IQueue` implementation by extending `QueueBase`: - -- **`EnsureQueueCreatedAsync`** always receives `DisposedCancellationToken`. Use it for all setup operations (lock acquisition, API calls, etc.). -- **`DequeueImplAsync`** receives a linked token (caller + disposal). Respect it for the wait/poll operation. -- **`EnqueueImplAsync`** does not receive a cancellation token — keep enqueue fast and non-blocking. - -## Best Practices - -### 1. Proper Resource Disposal - -Queues implement `IDisposable` and should be properly disposed: +Queued work uses the same `IMessageBus` client as pub/sub, with explicit consumer registration. `SendAsync` targets competing consumers; `PublishAsync` targets event subscriptions. ```csharp -// ✅ Good: Using statement for short-lived queues -await using var queue = new InMemoryQueue(); -await queue.EnqueueAsync(new WorkItem { Id = 1 }); - -// ✅ Good: DI container manages lifetime -services.AddSingleton>(sp => - new InMemoryQueue()); +builder.Services.AddFoundatioWorker(foundatio => foundatio + .Messaging.UseInMemory() + .Messaging.AddConsumer()); -// ❌ Bad: Not disposing -var queue = new InMemoryQueue(); -// ... use queue -// Queue is never disposed, resources leak +await bus.SendAsync(new ProcessOrder(1001)); ``` -### 2. Use Typed Messages +Implement `IMessageHandler` and process the message in `HandleAsync`. Successful handlers are acknowledged automatically; failures use the retry/dead-letter policy. Replicas compete for the queue, and each invocation gets its own dependency injection scope. Use idempotent processing because a message may be delivered again after a crash or uncertain acknowledgement. -```csharp -// ✅ Good: Typed, versioned messages -public record OrderWorkItem -{ - public int Version { get; init; } = 1; - public required int OrderId { get; init; } - public required DateTime CreatedAt { get; init; } -} - -// ❌ Bad: Generic, untyped -public class WorkItem -{ - public object Data { get; set; } -} -``` +For manual loops, `ReceiveAsync` returns a disposable delivery with complete, reject, and renewal operations. Disposing an unfinished delivery returns it for redelivery. See [Messaging](messaging.md) for direct receive examples, concurrency, delays, topology, dead-letter administration, and provider guarantees. -### 2. Handle Idempotency - -```csharp -var entry = await queue.DequeueAsync(); -if (entry is null) - return; - -// Check if already processed -if (await _processedIds.ContainsAsync(entry.Value.Id)) -{ - await entry.CompleteAsync(); - return; -} - -// Process -await ProcessAsync(entry.Value); - -// Mark as processed -await _processedIds.AddAsync(entry.Value.Id); -await entry.CompleteAsync(); -``` - -### 3. Set Appropriate Timeouts - -```csharp -var queue = new RedisQueue(o => { - o.WorkItemTimeout = TimeSpan.FromMinutes(5); // How long to process - o.RetryDelay = TimeSpan.FromSeconds(30); // Delay before retry - o.Retries = 3; // Max retries -}); -``` - -### 4. Monitor Queue Depth - -```csharp -var stats = await queue.GetQueueStatsAsync(); -if (stats.Queued > 1000) -{ - _logger.LogWarning("Queue depth is high: {Depth}", stats.Queued); - // Consider scaling workers -} -``` - -### 5. Use Delayed Delivery for Scheduling - -```csharp -// Schedule for later -await queue.EnqueueAsync(reminder, new QueueEntryOptions -{ - DeliveryDelay = TimeSpan.FromHours(24) -}); -``` - -## Queue Name vs Queue ID - -Every queue has two distinct identifiers that serve different purposes: - -| Property | Purpose | Stable across restarts? | Shared across processes? | -|----------|---------|------------------------|--------------------------| -| `Name` | Identifies the queue in the **backing store** (Redis key prefix, SQS queue name, etc.) | ✅ Yes | ✅ Yes — two processes with the same `Name` share the same data | -| `QueueId` | Runtime **instance identifier** used only for logging and diagnostics | ❌ No (random suffix by default) | N/A — never used for data routing | - -**`Name`** is what controls which data is read and written. All distributed queue implementations (Redis, SQS, Azure Service Bus, Azure Storage) route messages based on `Name`, not `QueueId`. Two processes or application restarts using the same `Name` will naturally share queue data and continue from where the other left off. - -**`QueueId`** exists purely so that multiple queue instances within the same process (e.g., priority queues or keyed queues) produce distinguishable log output. It has no effect on the backing store. - -::: tip Sharing queues across processes -If you want multiple processes (or application restarts) to share a queue, just ensure they all configure the same `Name` value.

not single keywords. All provider docs (Redis, Az - One messaging client: `IMessageBus` in `Foundatio.Messaging`. `SendAsync` targets competing queue consumers; `PublishAsync` fans out to existing event subscriptions. Delivery is at least once where supported, so handlers must tolerate duplicates. Both return application IDs, independently of broker IDs. Supply `MessageSendOptions.MessageId` / `MessagePublishOptions.MessageId` for retry correlation; this does not create exactly-once delivery. Batches return IDs in input order; `MessageSendException.Outcomes` distinguishes accepted, unknown, and unattempted inputs on failure. - Publish has real pub/sub DROP semantics: a publish to a topic with no existing subscriptions is dropped (subscriptions are created when handlers subscribe or via topology provisioning -- subscribers must exist before the publish). A sent command waits durably on its queue instead. The in-memory transport warns once per topic on zero-subscription drops, and the core logs every produce at debug. -- Implement `IMessageHandler` and explicitly register `.Messaging.AddConsumer()` for queued work or `.Messaging.AddSubscriber("billing")` for events. Each message uses its own DI scope. Dynamic equivalents are `ConsumeAsync` and `SubscribeAsync`, returning an `IMessageSubscription` with its structural `Source` address. -- `MessageConsumerOptions` sets an optional queue destination. `MessageSubscriptionOptions` sets an optional topic and explicit durable subscription name: replicas using the same name compete. In dynamic SubscribeAsync, null creates a temporary listener with a renewable expiration lease on in-memory/Redis; AWS requires a durable name.

Manual acknowledgement holds its concurrency slot until settlement. +- Implement `IMessageHandler` and explicitly register `.Messaging.AddConsumer()` for queued work or `.Messaging.AddSubscriber("billing")` for events. Each message uses its own DI scope. Dynamic equivalents are `ConsumeAsync` and `SubscribeAsync`, returning an `IMessageSubscription` with its structural `Source` address, Status, RecoveryVersion and WaitUntilReadyAsync. Transient temporary-lease renewal errors retry; definite loss recreates the listener. Derived local state must resynchronize after a recovery gap; HybridCacheClient clears its local cache automatically. +- `MessageConsumerOptions` sets an optional queue destination. MessageTypeName plus Destination/Topic on a handler binds its wire name and producer route; AddMessageType(name, queue: ..., topic: ...) does the same for producers. GetRouteMaps() and startup logs expose mappings; startup validates duplicate wire names even when topology mode is None. `MessageSubscriptionOptions` sets an optional topic and optional durable subscription name (declarative default: UseServiceName, then hosting ApplicationName): replicas using the same name compete. In dynamic SubscribeAsync, null creates a temporary listener with a renewable expiration lease on in-memory/Redis; AWS requires a durable name. Shared `MessageHandlerOptions` controls endpoint concurrency (default 1), retries and acknowledgement. Duplicate concrete handlers and multiple interface/raw fallback handlers on one endpoint are rejected. Manual acknowledgement holds its concurrency slot until settlement. - Routing is central: `.Messaging.ConfigureRouting(r => r.UseDefaultQueue(...).UseDefaultTopic(...).MapQueue(...).MapTopic(...).UseConvention(...))`. Precedence: operation override > exact map > interface/base-type map > `MessageRouteAttribute` > configured default > convention > kebab-cased type name. Producer routing declares queues/topics, never phantom subscriber groups. - Routing config doubles as topology declarations (`DestinationDeclaration` with a canonical `DestinationAddress` -- `ForQueue`/`ForTopic`/`ForSubscription`). `IMessageTopology` exposes `GetDeclarations()` / `EnsureAsync()` / `ValidateAsync()`. `.Messaging.ConfigureTopology(TopologyMode.Ensure | Validate | None)` picks whether the client creates missing destinations (default), only verifies they exist (throws at startup when missing), or never touches topology; AddMessageConsumers includes startup topology; producers can opt in with AddMessagingTopology. Registering a transport starts no hosted services. - The CORE owns retry/dead-lettering identically on every transport: default `RetryPolicy` is `MaxAttempts` 5 with immediate-then-10s/20s/30s backoff (+/-20% jitter); configure via `.Messaging.ConfigureRetry(p => p with { ... })`. Dead-lettered messages go to the transport's native sink or a derived `"{source}.deadletter"` destination, stamped with `message.dead_letter.*` forensics headers (`KnownHeaders.DeadLetter*`). Never configure broker-native redrive policies. - Settlement succeeds only after the broker operation succeeds. A failed DLQ write leaves the original unsettled. `IMessageContext` exposes application `Id`, diagnostic `BrokerMessageId`, `CompleteAsync`, `RejectAsync`, and cancellation. Expiring delivery leases are supervised and renewed while a handler runs; lease loss cancels the handler and prevents settlement. Direct loops use `await using var message = await bus.ReceiveAsync(options, token)`; disposal returns unfinished work for redelivery. Raw receive requires an explicit destination. - Transports advertise per-destination capabilities: `ITransportInfo.GetCapabilities(destination)` takes the `DestinationAddress` in question (most transports answer by its role) and returns `TransportCapabilities` (e.g. the AWS transport's queue role has a native 15-minute `MaxDeliveryDelay`; its topic role has none). Delays beyond a ceiling and store-parked retries fall back to the durable runtime store (`IScheduledDispatchStore`, satisfied by any `IJobRuntimeStore`) and are drained by an explicitly hosted ScheduledMessageDispatcher -- never silently truncated. - Durable jobs: implement `IJob` (`Task RunAsync(JobExecutionContext context)`). `JobResult` is an immutable record -- return the shared `JobResult.Success`/`JobResult.Cancelled` statics or the `SuccessWithMessage`/`FailedWithMessage`/`CancelledWithMessage`/`FromException` factories (there is no `None`). `IJobClient.EnqueueAsync()` / `EnqueueAsync(args)` (typed payloads) returns a `JobHandle`; `IJobMonitor` queries state; `IJobWorker` executes with per-run DI scopes, bounded concurrency, and supervised lease renewal. `JobExecutionContext` gives `JobId`/`Attempt`/`CancellationToken`, `GetArguments()`, `ReportProgressAsync`, `RenewLeaseAsync`, `IsCancellationRequestedAsync`; its public constructor makes a detached context for tests. `GetArguments` enforces the stored payload-type discriminator: requesting a different type than the job was enqueued with throws before deserialization. Hand-wiring outside DI: `JobWorker`/`JobScheduleProcessor` take `JobWorkerOptions`/`JobScheduleProcessorOptions` records for their optional dependencies. -- CRON: `.Jobs.AddCronJob(cron)` or `.Jobs.AddCronJob(cron,args)`; typed jobs implement `IJob`. Schedules persist wire names, serialized payloads, time-zone IDs, retry budgets, and revisions. `ConfigurationVersion` must increase for a changed declaration; same-version restarts preserve runtime edits. `ScheduleAsync` uses revision checks. Global and per-node occurrences share the same job worker/state machine. +- CRON: `.Jobs.AddCronJob(cron)` or `.Jobs.AddCronJob(cron,args)`; typed jobs implement `IJob`. Schedules persist wire names, serialized payloads, time-zone IDs, retry budgets, and revisions. `ConfigurationVersion` must increase for a changed declaration; same-version restarts preserve runtime edits. `ScheduleAsync` uses revision checks. Global and per-node occurrences share the same job worker/state machine. Global is the default. PerNode requires Jobs.ConfigureWorker(o => o with { NodeId = ... }) or FOUNDATIO_NODE_ID; unclaimed occurrences expire after configurable UnclaimedLifetime (one day). Cache confirmed materializations only: OverlapBlocked must be retried within the misfire window. - `AddFoundatioWorker` validates missing transports/stores during registration. Receiving options, durable names, concrete job types, and schedule options also fail at registration. With individually hosted roles, startup validation fails fast at boot with actionable messages: CRON jobs registered without a runtime store, or handlers registered without a transport, throw when the corresponding consumer/scheduler host starts (add `.Jobs.UseInMemory()` / `.Messaging.UseInMemory()` or the production `Use*`). - Jobs exceptions on the trigger/resolve paths: `ScheduledJobNotFoundException` (unknown schedule name), `ScheduledJobDisabledException` (triggering a disabled schedule), and `JobException` (unresolvable job type); all derive from `JobException` : `InvalidOperationException`. - Schedule management: `IScheduledJobManager` supports inspect, revision-checked updates, enable/disable, reschedule, remove, and manual trigger. Manual triggers respect disabled/overlap policy. Removing a definition does not cancel already queued jobs. -- Stable wire names: `.Messaging.AddMessageType("order-created.v1")` and `.Jobs.AddJobType("name")` preserve persisted discriminators across refactors. Polymorphic message deserialization resolves only explicitly registered names; it never scans loaded assemblies. Concrete handlers can use the default CLR full name. Producers and consumers must use the same serializer/content type.

Choose `AddConsumer` or `AddSubscriber`, and use a stable service identity or explicit names for durable subscribers. diff --git a/docs/guide/queues.md b/docs/guide/queues.md index be74e3bda..b079c93e9 100644 --- a/docs/guide/queues.md +++ b/docs/guide/queues.md @@ -5,7 +5,7 @@ Queued work uses the same `IMessageBus` client as pub/sub, with explicit consume ```csharp builder.Services.AddFoundatioWorker(foundatio => foundatio .Messaging.UseInMemory() - .Messaging.AddConsumer()); + .AddConsumer()); await bus.SendAsync(new ProcessOrder(1001)); ``` diff --git a/samples/Foundatio.MessagingSample/Program.cs b/samples/Foundatio.MessagingSample/Program.cs index f70999e23..fa45981e9 100644 --- a/samples/Foundatio.MessagingSample/Program.cs +++ b/samples/Foundatio.MessagingSample/Program.cs @@ -9,18 +9,18 @@ builder.Services.AddSingleton(new InstanceInfo(Guid.NewGuid().ToString("N")[..6])); builder.Services.AddFoundatioWorker(foundatio => foundatio - // Queue consumers compete; each named event subscription receives its own copy. - .Messaging.UseAws() - .Messaging.AddConsumer() - .Messaging.AddSubscriber("announcements") // one replica in this durable subscriber group - // Persisted jobs on Redis. - .Jobs.UseRedis() - .Jobs.AddJobType("generate-report") // on-demand, submitted via POST /reports - .Jobs.AddCronJob("* * * * *") // Global: one instance per tick - .Jobs.AddCronJob("* * * * *", o => o.Scope = ScheduledJobScope.PerNode) // every instance per tick - .Jobs.AddCronJob("*/2 * * * *")); // Global: periodic sweep + .UseServiceName("messaging-sample") + .ConfigureMessaging(messaging => messaging.UseAws() + .AddConsumer() + .AddSubscriber()) + .ConfigureJobs(jobs => jobs.UseRedis() + .AddJobType("generate-report") + .AddCronJob("* * * * *") + .AddCronJob("* * * * *") + .AddCronJob("*/2 * * * *"))); var app = builder.Build(); +app.MapHealthChecks("/health"); app.MapGet("/", (InstanceInfo instance) => Results.Ok(new { service = "Foundatio messaging sample", instance = instance.Id })); diff --git a/samples/Foundatio.QuickstartSample/Handlers.cs b/samples/Foundatio.QuickstartSample/Handlers.cs index c4d0c0013..bc703b0ba 100644 --- a/samples/Foundatio.QuickstartSample/Handlers.cs +++ b/samples/Foundatio.QuickstartSample/Handlers.cs @@ -8,24 +8,26 @@ namespace Foundatio.QuickstartSample; /// because Program.cs calls bus.PublishAsync.

A worker can finish a business operation and crash before acknowledgement. Lease renewal reduces concurrent execution but cannot guarantee exactly-once side effects.

Concrete handlers may use the default CLR full-name discriminator; interface, abstract, and `object` receivers accept only explicitly registered concrete types.

Payload is 1 KiB, with three seconds of warmup followed by fifteen seconds of publishing by default. +- `extended`: 16 KiB queue/fanout payloads and ten-input queue/fanout batch API calls. +- `soak`: two-minute concurrent queue and four-subscriber fanout runs per implementation. + +The standard profile runs 20 configurations × 3 repetitions = 60 fresh processes. Allow roughly 20–30 minutes, including warmup, broker setup, draining and cleanup. Trials run sequentially in seeded shuffled order, so two contenders never load the same broker simultaneously. Time windows exclude topology creation, startup, warmup, cleanup and JSON report generation. Do not build, run tests, profile, or run other workloads concurrently with measurements. + +Results go to a timestamped `results/` directory: individual JSON/log files, throughput ranges and medians in `summary.md`, `summary.csv`, runtime information and repository state. The measurement executable exits nonzero for send/receive failures, missing or invalid deliveries, duplicates, timeout, cleanup failure or exhausted tracking capacity. Invalid trials are excluded from successful summaries and listed explicitly. Inspect failures before comparing throughput. + +## What is compared + +| Engine | Transport | Meaning | +| --- | --- | --- | +| Foundatio | In-memory | Full serialization, routing, receive and acknowledgement path | +| MassTransit 8.5.10 | In-memory | Full MassTransit pipeline using its own in-memory transport | +| Foundatio | Redis Streams | Real Redis broker, durable consumer groups and acknowledgements | +| Foundatio | SQS/SNS | Shared-broker comparison against MassTransit | +| MassTransit 8.5.10 | SQS/SNS | Same SQS queues / SNS fanout semantics and broker instance, with separate run namespaces | + +MassTransit has no Redis Streams transport. Its Redis saga repository is not a message transport. The two in-memory implementations have different internals and are not wire-compatible. The SQS/SNS comparison is the shared-transport comparison. LocalStack is an emulator: use those results to investigate client/API behavior, not to predict AWS service throughput or latency. + +MassTransit 8.5.10 is pinned as the latest Apache-licensed v8 release available when this suite was created. Its package version is an MSBuild property so another supported version can be tested deliberately. The benchmark project is isolated from shipping packages. Both contenders run in the same executable dependency graph and use the same AWS SDK/runtime versions; actual versions are embedded in every JSON result. No application contracts or messages pass between the contenders. + +All cases use the same ASCII payload, producer parallelism and per-endpoint consumer limit. MassTransit prefetch is explicitly matched to that limit. Fanout uses separate durable subscription queues, and per-endpoint concurrency is reported rather than pretending that four subscriptions have the same total concurrency as one. The baseline calls the ordinary send/publish API once per input. Batch cases call each library's public batch API; native batching, pipelining and acknowledgement buffering remain part of the implementation being measured. Collection size does not imply a single atomic broker request. Default serializers/envelopes remain enabled, so equal application payload sizes do not imply equal wire bytes. + +## Measurement contract + +- Delivery latency starts immediately before submission and ends after broker acknowledgement. Foundatio explicitly completes its manual delivery before recording it. MassTransit's `IReceiveObserver.PostReceive` runs after `ReceiveLock.Complete`; its consumer attaches the message to the receive context for that observer. This instrumentation and payload validation are included in client CPU/allocation totals. +- Queue throughput counts unique acknowledged inputs. Pub/sub reports both inputs/second and deliveries/second: one input with four subscribers produces four expected deliveries. The denominator includes draining the last submitted work, preventing an undrained backlog from looking like throughput. +- The outstanding window bounds admitted inputs and releases an input only when all its subscriber copies have acknowledged. It is not a fire-and-forget producer benchmark. Every input/subscriber pair is tracked separately; duplicate copies cannot hide missing fanout. +- The tracking arrays are allocated before measurement. Their size is bounded by `--max-messages`; hitting that limit invalidates the trial rather than silently shortening it. The suite uses a 20-million-input ceiling; long/faster runs may require splitting trials. Working-set results include those fixed tracking arrays and warmup state. +- Per-process allocated bytes, CPU time, GC collections and pauses cover producer, consumers and harness. They exclude Redis/LocalStack processes. One-second samples preserve backlog, throughput and working-set trends. `SendCallLatency` is per API call, so a batch of ten represents ten inputs. +- Latency histograms retain all samples, including slow tails, in fixed storage with one-microsecond resolution below 64 microseconds and at most approximately 1.6 percent bucket width above it. Percentiles use bucket upper bounds; maximum is exact to the recorded microsecond. Reported p50/p95/p99 are medians of each trial's percentiles, not a percentile formed by averaging durations. +- Saturation tests (`--rate 0`) are bounded closed-loop tests. Offered-rate tests use each input's intended schedule as its latency origin, including time waiting for producer capacity. They expose scheduling/backpressure delay instead of hiding coordinated omission. If the configured offered rate is not achieved, report that deficit; these tests do not create an unlimited external arrival queue. +- Automatic retries and at-least-once delivery can produce duplicates. Those are reported and invalidate the performance comparison for investigation; this does not claim either library guarantees exactly-once side effects. + +## Individual and offered-rate cases + +```powershell +$runner = 'benchmarks/Messaging/bin/Release/net10.0/Foundatio.Messaging.Benchmarks.dll' +dotnet $runner --engine foundatio --transport redis --scenario queue --seconds 30 --warmup 5 --producers 32 --consumers 32 --prefetch 32 --outstanding 1024 --payload 1024 --output redis-queue.json + +dotnet $runner --engine masstransit --transport sqs --scenario pubsub --subscribers 4 --seconds 30 --producers 8 --consumers 8 --prefetch 8 --rate 200 --outstanding 1024 --output sqs-rate200.json + +# Sanity-check the shared tracking/generation overhead without serialization or a broker. +dotnet $runner --engine loopback --transport memory --scenario queue --seconds 5 --output harness-overhead.json +``` + +For connection overrides use `PERF_REDIS`, `PERF_AWS_URL` and `PERF_AWS_REGION`.

The transport starts at a 25 ms poll interval and backs off up to one second when idle. Compare a tighter cap or a wake-up mechanism against idle CPU and broker request cost before changing defaults. +4. Repeat on a dedicated client host against live AWS in the same region, including several offered rates and longer runs. LocalStack numbers describe this emulator and client pipeline; they cannot size AWS. Keep the serial, fanout, payload and low-rate cases so an improvement in saturation throughput does not hide a usability regression. + +[Reproduction instructions and measurement contract](README.md) · [Raw trials, metadata and summaries](baselines/2026-09-06/) · [Pinned MassTransit queue batching](https://github.com/MassTransit/MassTransit/blob/62ab339afa3bac2e9b3fe1769d0d35d7e44778e9/src/Transports/MassTransit.AmazonSqsTransport/AmazonSqsTransport/QueueInfo.cs) · [Pinned MassTransit topic batching](https://github.com/MassTransit/MassTransit/blob/62ab339afa3bac2e9b3fe1769d0d35d7e44778e9/src/Transports/MassTransit.AmazonSqsTransport/AmazonSqsTransport/TopicInfo.cs) diff --git a/benchmarks/Messaging/baselines/2026-09-06/README.md b/benchmarks/Messaging/baselines/2026-09-06/README.md new file mode 100644 index 000000000..216a0ee8b --- /dev/null +++ b/benchmarks/Messaging/baselines/2026-09-06/README.md @@ -0,0 +1,19 @@ +# Raw messaging benchmark evidence + +`raw-trials.tar.gz` contains all 141 JSON trial records, worker logs, per-profile metadata and summaries.

Acknowledgement collection also learns the requested receive capacity, so a consumer with fewer than ten slots can flush a complete batch immediately; queued receipts can still fill all ten native slots. Disabling automatic batching leaves explicit batch sends available. Canceling a caller does not cancel other messages sharing its AWS request. The collector skips canceled buffered operations; cancellation racing dispatch can leave an unknown send outcome. Disposal drains admitted operations and cancels unfinished requests at the batch timeout. Missing or failed delete results never count as acknowledgements. The AWS receiver caps each pull at ten and overlaps up to four receive requests when consumer capacity permits. Receives share one slot budget and collect freed slots together, starting immediately when a batch fills. `MaxConcurrency` remains a strict bound on unacknowledged deliveries; a slow handler does not block unrelated slots.

Client allocation, end-to-end throughput and tail latency are separate measurements; no across-the-board allocation claim is made. + +## Changes + +- Receive-slot collection dispatches as soon as its batch fills. AWS can overlap up to four receives under one shared consumer budget; collection is serialized so simultaneous receivers do not split a useful batch into tiny requests. +- A settled handler releases its delivery capacity independently of slow cancellation callbacks. Deferred cancellation and lease cleanup have a separate bounded budget and are drained on shutdown. +- Ordinary AWS sends, publishes and acknowledgements coalesce automatically. Partial operation batches wait up to two milliseconds, subject to timer scheduling. SQS sends can dispatch immediately when idle; singleton streams skip repeated idle waits. Acknowledgements learn the maximum requested receive batch size, so an eight-slot consumer does not wait for two additional receipts. Already queued receipts can still fill the native ten-entry batch. Slow handlers retain the bounded partial-batch timeout. +- Batch collection no longer creates a cancellation exception for each timer expiry; normal lease-timer cancellation also avoids exception handling. Batch responses still validate individual outcomes, caller cancellation cannot cancel another caller's shared request, and admitted work drains before owned SDK clients are disposed. +- A versioned `fnd.envelope` AWS attribute carries the ID, content type, encoding and all headers. JSON/text bodies stay readable and binary bodies use base64. An empty-by-default `NativeMessageHeaders` collection can duplicate up to nine selected headers for SNS attribute filters. Names are validated and snapshotted at construction. +- Benchmark reports fingerprint the actual CoreCLR binary. `run.ps1 -DotnetPath` selects the worker host, and the summarizer rejects mixed runtime builds even when their displayed version matches. + +The AWS wire/default-header change intentionally affects the unreleased provider: new readers accept the previous envelope format, but previous experimental readers cannot read new sends. Upgrade endpoints together or use a new resource prefix. Existing native SNS attribute filters must select their header names explicitly; application handlers continue receiving all headers. + +## Measurement method + +The final implementation is `77c20ea354919fd25ae300e49c5de7f3ed8da598`. Preserved before binaries are the previous automatic-batching implementation, `abce1c0e`, from checkout `466e3987`. Binary manifests identify all executables. MassTransit is 8.5.10, pinned to `62ab339afa3bac2e9b3fe1769d0d35d7e44778e9`, using the same AWS SDK assemblies. + +All confirmed trials invoke Microsoft's official .NET 10.0.11 runtime with CoreCLR SHA-256 `3ebe90cd92b1edf6742a41fa921a0c6326216fd1cca45fdb5e055bea33351bea`, server GC, on the same shared Linux x64 host (Ubuntu 26.04.1, AMD Ryzen AI 9 HX 470, 24 logical processors). LocalStack 3.8.1 is limited to four CPUs and 3 GiB; Redis 8.6 to four CPUs and 2 GiB, with AOF everysec. Workers run sequentially in seeded shuffled order, with no concurrent builds, tests or profiling. The host is shared and has no CPU affinity; small differences and overlapping ranges should be treated cautiously. + +Standard cases have three fresh-process repetitions, ten seconds of publishing after up to three seconds of warmup, 1 KiB payloads and a 1,024-input outstanding window. Concurrent queues and one-subscriber pub/sub use 32 producers and 32 consumer slots. Four-subscriber fanout uses 32 producers and eight consumer slots per subscription. MassTransit prefetch equals its per-endpoint consumer limit. Serial queues use one producer and one consumer with the same outstanding window; the separate window-one profile measures one-at-a-time round trips. + +Throughput includes final acknowledgement and drain. Fanout rates count inputs; each input requires four independently validated acknowledged deliveries. Saturation p99 includes the bounded backlog and is not unloaded latency. Offered-rate latency starts at the intended arrival schedule and includes capacity waits. Counts and CPU/allocations include client and harness, excluding broker processes. RSS includes fixed tracker arrays and can vary with the portion touched during a run; comparisons must use the same tracker capacity and cannot by themselves establish a live-object leak. + +Baseline harnesses predate the CoreCLR fingerprint field; their exact official-runtime invocation and DLL hashes are preserved in each profile manifest. Earlier Ubuntu-runtime experiments are retained separately and are excluded from final same-runtime comparisons. + +## Runtime investigation + +Earlier benchmark workers exited with native CLR error `0x80131506`. The system SDK build also terminated with that error during this follow-up. This is separate from a managed assertion or delivery-validation failure. The installed Ubuntu .NET 10.0.11 runtime links external libunwind 1.8.3, whereas Microsoft's same-version runtime does not. The Ubuntu package predates a concurrent-unwinding fix discussed in the [upstream runtime issue](https://github.com/dotnet/runtime/issues/130577) and [libunwind change](https://github.com/libunwind/libunwind/pull/993). + +A standalone .NET console program with no Foundatio dependencies repeatedly threw/caught exceptions with 24 workers. Five five-second trials per runtime produced no crash in either build. The official runtime processed approximately 6.8 times as many exceptions. This demonstrates a material runtime difference, but does not reproduce or prove the cause of the historical crashes. Both contenders now use the same official runtime for confirmation; no system runtime was replaced. Original dumps and failed trials remain retained, and the Ubuntu-host crash remains unresolved. + +## Scope + +LocalStack is an emulator. These results do not establish live AWS throughput or latency, and no AWS account was contacted. Live mode remains explicitly selectable with the SDK credential chain and the same configuration for both contenders. Redis Streams is measured against Foundatio's preserved implementation; there is no MassTransit Redis transport in this comparison. + +## Validation and retained evidence + +- Core: 2,036 passed / 12 skipped. AWS: 63 passed / 8 skipped. Redis: 56 passed / 4 skipped. Measurement: 16 passed. **2,171 passed, 24 expected skips, zero regression-test failures.** All suites used the official runtime. The new acknowledgement-capacity regression failed before the change and passed afterward; the full AWS suite was rerun after the final AWS change. +- `Foundatio.slnx` Release build passed, with only the pre-existing ASPIRE010 warning. The aggregate `Foundatio.All.slnx` could not build in the isolated clone because its external sibling repositories are absent. The repository solution includes the temporary AWS and Redis providers and their tests. +- Targeted whitespace formatting, `git diff --check`, documentation build and benchmark summary regressions passed. The summary tests reject mixed runtime binaries even when the displayed runtime versions match. +- Regression coverage includes full receive-batch dispatch, overlapping receives under one capacity bound, bounded cleanup with blocked cancellation callbacks, sibling cancellation before reprovisioning, shared-batch cancellation, timeout/disposal behavior, per-entry acknowledgement validation, legacy/malformed envelope decoding and native-header validation. A LocalStack SNS tenant-filter test verifies selected native headers. +- The final resource inventory found no benchmark SQS queues, SNS topics or Redis keys. Conformance tests left their own 84 queues and six topics in the disposable broker; these were removed with the task-owned containers. Other development services were not modified. +- The final record audit verified all 93 unique resource prefixes, full publishing windows, bounded sampled outstanding counts, acknowledgement counts and histogram totals. Every admitted delivery drained. No crash dump was generated; temporary crash settings applied only to the completed Redis workers. +- [Raw results, manifests, scripts and summaries](baselines/2026-09-07-pipelines/) are retained.

(the previous confirmed pipeline implementation). The main optimized matrix uses `0b3dfdc86687ab55d2ee6037e608fc97ac0a748d`. Final code and the after-traces use `e677cf9a4c53fdea468344f175a4d40f2a698c9a`, which additionally restores BOM-prefixed JSON compatibility. Both run under the preserved official Microsoft .NET 10.0.11 runtime. This pass does not replace the system runtime or contact an AWS account. + +Capture command: `dotnet-trace collect --profile gc-verbose --output .nettrace --show-child-io -- /Foundatio.Messaging.Benchmarks.dll --engine foundatio --transport sqs --scenario pubsub --seconds 30 --warmup 5 --producers 32 --consumers 8 --prefetch 8 --subscribers 4 --outstanding 1024 --max-messages 2000000 --payload <1024-or-16384> --output .json`. The comparison capture uses `--engine masstransit` with the same remaining arguments. All captured workloads use synthetic data and task-owned LocalStack resources. + +`TraceAnalysis` reads GCAllocationTick events and weights each sampled type/stack by AllocationAmount64. The analysis window is 12 to 30 seconds after trace start, excluding startup and final drain. Types and complete stacks are saved in JSON; inclusive method summaries can overlap. Sampling estimates allocation attribution, not precise per-method accounting. No missing events or missing allocation stacks were reported in the baseline analysis windows. The profiler's version is 10.0.731102; the offline reader uses the previously cached TraceEvent 3.1.21 package. See [Microsoft's dotnet-trace documentation](https://learn.microsoft.com/en-us/dotnet/core/diagnostics/dotnet-trace) for gc-verbose and collection options. + +Traced worker throughput/allocation totals are diagnostic only and are excluded from comparison medians. Untraced fresh-process trials measure total managed allocated bytes with GC.GetTotalAllocatedBytes, including SDK and harness work, excluding broker processes. Allocation per input counts four deliveries in fanout. It is allocation churn, not retained memory or isolated library overhead. Working-set observations include the benchmark's fixed tracking arrays and touched pages and cannot establish leak freedom. + +The untraced comparisons use 15-second publishing phases and 3-second warmup, a 1,024-input window, 32 producers, and 32 consumers for queues or eight consumers per subscriber for four-subscriber fanout. Prefetch equals per-endpoint consumer concurrency. Input tracking capacity is 20 million for every case, including 120-second soaks (5-second warmup). Each AWS payload/implementation/workload combination has three randomized repetitions. Redis large-payload checks and each sustained case have one repetition. In-memory checks compare the preserved baseline to the optimized code. Exact invocations, DLL hashes, logs and JSON results are saved per profile. + +Acknowledgement and final drain remain included in throughput. Every input/delivery is validated for missing, duplicate, and invalid delivery. No builds, test suites, or other profiling jobs run alongside measured workers. Other host workloads were left running, so small rate differences and overlapping ranges are treated cautiously. LocalStack is a broker emulator; these results do not establish live AWS performance. + +The optimization adds optional IBufferSerializer support selected automatically by existing extensions; the default JSON serializer preserves stream options, runtime types, null handling and primitive normalization. Existing serializers retain the stream fallback. AWS sends skip temporary per-message batching lists, build SDK attributes directly, and allocate unknown outcomes only for unconfirmed entries. Receive requests retain all application attributes and request only the system receive count used by the transport. Checksum validation, retry, cancellation, acknowledgements, and bounded batching remain enabled. No wire-format change is introduced in this allocation pass. + +Final-revision confirmation adds five 30-second in-memory queue trials per implementation, three 20-second Redis fanout trials per implementation, and one final AWS trial per workload/payload. Both repeats use up to five seconds of warmup, capped at one million inputs. Main matrix and final-revision profiles are summarized separately, without combining their medians. diff --git a/benchmarks/Messaging/baselines/2026-09-07-allocations/profiles.json b/benchmarks/Messaging/baselines/2026-09-07-allocations/profiles.json new file mode 100644 index 000000000..ef2955c96 --- /dev/null +++ b/benchmarks/Messaging/baselines/2026-09-07-allocations/profiles.json @@ -0,0 +1,53 @@ +[ + [ + "aws-1024", + [ + "--payload", + "1024" + ] + ], + [ + "aws-16384", + [ + "--payload", + "16384" + ] + ], + [ + "memory", + [ + "--transport", + "memory", + "--variants", + "before,after" + ] + ], + [ + "redis-16384", + [ + "--transport", + "redis", + "--variants", + "before,after", + "--payload", + "16384", + "--repetitions", + "1" + ] + ], + [ + "aws-soak", + [ + "--variants", + "after,masstransit", + "--seconds", + "120", + "--warmup", + "5", + "--repetitions", + "1", + "--payload", + "16384" + ] + ] +] \ No newline at end of file diff --git a/benchmarks/Messaging/baselines/2026-09-07-allocations/raw-results.tar.gz b/benchmarks/Messaging/baselines/2026-09-07-allocations/raw-results.tar.gz new file mode 100644 index 0000000000000000000000000000000000000000..8a5c0750580d524530a4d37b2c56eb99d264f7ff GIT binary patch literal 163479 zcmaHSWl&se8zk;wkYEWgxH|-QcMl2f7Tkjl8r(Iw6GCuz2<`-T5?n)IAiw}~mV3W% zcWbM5_s5(%Rdc3lew^;7pYDFau^1R0fAc>e0q*8L?C#bcUXGp~9G>Rx2xr|69ve&P z{Mj>bBDS|`TH?t+yEz`pS=1=>Gg23FVn;k#T;4L2N&A#IB`|B-q_*&i!!K;vuZcEa zuh@l@vk^|JS_sS{_?e%3A?DkP4KWTe0v9CviI8vO`d&|+rh7ANz#4p+bmv^+^w13N zj}M~+{5K`snM7c}IT!8&f`SIda&n*oiynWd??|cdzM~V0&MEZ127;iFeNb#g!^T~z z=^yfrFWs%M-k;U0Puo-3=&@(jmeSFv!FE

AWS managed resources do not advertise native TTL expiration.

Providers without native inspection use bounded receive/hold/release. Scans stop at 1,000 messages or ten seconds; their cleanup has an independent timeout.

No caller API changes are required. +This follow-up reduces per-message work without changing application APIs. It builds on Foundatio `54006ac7` and Mediator `ff9c155`; measured source/binary fingerprints are in the linked raw data. Mediator core still matches main `a148013`. -- Redis caches encoded index names, updates only changed status/expiry indexes, and reads only history entries that actually need removal. -- Admission combines bounded expired-history cleanup and capacity checks in one script; individual reads expire and load the requested job atomically. -- Snapshot parsing avoids temporary arrays and per-field string keys. Header builders copy only when reused after publishing a snapshot. -- Routine cancellation polling shutdown avoids throwing an exception; uncancellable operations avoid an unnecessary linked token source. +- Single-message sends avoid successful-batch bookkeeping while preserving acceptance uncertainty and provider failure details. +- Header builders share immutable snapshots until an edit; automatic settlement and unused lease renewal avoid allocating semaphores. +- In-memory receipts use object identity instead of generating a GUID for every delivery.

Throughput improves **8% at concurrency 1** and **6% at concurrency 8**. High-concurrency memory and LocalStack are near the baseline; this pass does not establish a throughput gain there. -All runs used the normal Ubuntu `/usr/bin/dotnet` (.NET 10.0.11), Release, concurrency 64, a 256-character payload, and a 1,000-message warmup. Redis workloads process 10,000 messages, untracked memory 200,000, and tracked memory 50,000. Redis and LocalStack 3.8.1 run locally. Three alternating repetitions per cell, except eight native memory-tracking runs. Timing includes broker drain and verified tracked completion; startup and warmup are excluded. These are shared-host diagnostics, not production AWS capacity estimates. +Redis short runs varied: an exploratory batch favored the change, while the table measured 8.3% lower throughput. Five additional alternating pairs of **30,000 Redis-tracked jobs** measured **6,380 → 6,503 jobs/s**, **47,323 → 45,839 bytes/job**, and **16,474 → 14,290 ms process CPU** (13% less). Acceptance p99 was 11.34 → 10.71 ms. The evidence supports lower allocation/CPU cost, with no consistent throughput gain.

The existing AppHost ASPIRE010 warning remains. +## Correctness and recovery -These changes preserve atomic capacity checks, attempt fencing, retention, and explicit broker/runtime ownership. PR #149 still has lower in-memory overhead; the full comparison reports that tradeoff. +The full Foundatio build and **2,229 tests pass**, with 24 existing skips and the existing AppHost ASPIRE010 warning. Mediator builds with zero warnings and **756 tests pass**. Added coverage checks cancellation at exact history expiry, partial/malformed send results, immutable snapshots, overlapping settlement, stale receipt settlement/renewal, and repeated scoped header restoration. + +The final comparison completed **63 successful runs and 4.32M measured jobs** without missing or duplicate delivery. One additional PR #149 trial and one Mediator build hit the previously observed CLR abort and passed their same-runtime retries; failures remain in the evidence. No runtime installation changed. + +A separate two-minute LocalStack/Redis arrival test accepted **46,504 jobs**: **46,464 completed**, **20 cancelled while queued**, and **20 while running**. A process was killed with **32 handlers in flight**; all 32 retried after replacement. Another worker gracefully stopped and restarted while arrivals continued. No pending, failed, dead-lettered or acceptance-unknown jobs remained. The application effect was idempotent, with zero duplicate effect attempts observed; delivery remains at least once.

It builds on Foundatio `54006ac7` and Mediator `ff9c155`; measured source/binary fingerprints are in the linked raw data. Mediator core still matches main `a148013`. +This pass removes lease-monitoring work from short deliveries while preserving renewal, expiry, cancellation and settlement races. The asynchronous monitor starts at the first scheduled lease check; a timer supervises the delivery from admission. Six new regressions cover its lifecycle. -- Single-message sends avoid successful-batch bookkeeping while preserving acceptance uncertainty and provider failure details. -- Header builders share immutable snapshots until an edit; automatic settlement and unused lease renewal avoid allocating semaphores. -- In-memory receipts use object identity instead of generating a GUID for every delivery. Stale receipts still cannot settle or renew a redelivery. -- Redis cancellation combines targeted expiry and the cancellation read in one atomic operation. -- The Mediator extension caches immutable registration metadata and skips empty provider enumeration; ordinary middleware and scoped dependencies still run per invocation. +External project references now preserve Release/Debug configuration through the entire graph. Previously a Release Mediator solution build could copy Debug native dependencies.

A process was killed with **32 handlers in flight**; all 32 retried after replacement. Another worker gracefully stopped and restarted while arrivals continued. No pending, failed, dead-lettered or acceptance-unknown jobs remained. The application effect was idempotent, with zero duplicate effect attempts observed; delivery remains at least once. The linked full report includes the reproducible recovery harness. +A ten-minute LocalStack/Redis run accepted **69,354 jobs**; **69,314 completed** and **40 were intentionally cancelled**.

SNS/SQS pub/sub by 4.0 times, and four-subscriber fanout by 3.3 times versus the preserved implementation. In this LocalStack comparison, Foundatio is faster than MassTransit on serial queues, approximately tied on one-subscriber pub/sub, 10% behind on concurrent queues and 28% behind on four-subscriber fanout. These are measured results, not a claim that Foundatio is universally faster. + +All 54 final trials succeeded: 1,113,065 measured inputs and 1,522,595 acknowledged deliveries, with zero missing, duplicate or invalid deliveries. The earlier 36-case batching comparison and six-case refinement check are retained separately; together these 96 trials validated 1,982,868 deliveries. No native worker crashes occurred in this follow-up. The unresolved native CLR failures in the [earlier baseline](RESULTS.md#harness-control-and-failures) remain a release blocker. + +## Repeated comparison + +Three fresh-process repetitions per cell, ten seconds of publishing after up to three seconds of warmup. Values are medians; throughput includes final acknowledgement and drain. Payload is 1 KiB and the outstanding window is 1,024 inputs. Concurrent queues use 32 producer workers and 32 consumer slots; fanout uses 32 producers and eight slots in each of four subscriptions. Serial means one producer worker and one consumer slot, with the same outstanding window; it is not a one-at-a-time round-trip test.

It is not unloaded service latency. Three samples and a shared host do not establish statistical significance for small differences; the observed throughput ranges are retained in the per-revision summaries. + +## What changed + +- Ordinary concurrent send, publish and complete calls now coalesce into native AWS requests. Application code keeps using the single-message API. Per-entry outcomes and broker message IDs remain attached to the correct caller. +- Automatic batching defaults to ten entries, at most 100 buffered operations and four active requests per destination and operation. Additional callers await capacity. Encoded bytes are bounded separately: SQS 1 MiB, SNS 256 KiB. Partial batches collect for up to one millisecond; idle singleton streams skip repeated waits. Shared requests and disposal drains have a 30-second timeout. Explicit batch calls retain their existing chunked behavior. +- Acknowledgement waits for the broker response. Missing, failed or invalid delete results do not report success. Canceling one caller cannot cancel other messages sharing its request; an uncertain send remains unknown. Disposal drains admitted work before owned SDK clients are disposed. +- AWS advertises its ten-message receive limit. The core briefly collects freed slots before another small pull, while maintaining a strict per-delivery concurrency budget and allowing a completed delivery to free its slot independently of slower handlers. Other providers retain zero receive delay. +- The batch worker does not inherit the first caller's async context. A regression reproduced retention of that request-scoped state on subsequent calls and now passes. Wire encoding, native headers and normal lease supervision remain enabled. + +## Broker request evidence + +These six additional ten-second trials have no warmup. Counts come from LocalStack operation logs and therefore also include startup, drain and cleanup. The table selects only send/publish, receive and delete operations. Receive counts can include empty polls. Entries per request are calculated from the fully validated measured input/delivery counts. + +| Workload / implementation | Send or publish entries/request | Deliveries/receive request | Receipts/delete request | +| --- | ---: | ---: | ---: | +| Concurrent queue / before | 1.00 | 9.99 | 1.00 | +| Concurrent queue / after | 6.97 | 9.98 | 9.91 | +| Concurrent queue / masstransit | 8.14 | 8.15 | 8.09 | +| Four-subscriber fanout / before | 1.00 | 3.58 | 1.00 | +| Four-subscriber fanout / after | 5.14 | 6.68 | 6.48 | +| Four-subscriber fanout / masstransit | 7.63 | 7.99 | 7.81 | + +The original code used the batch-send endpoint with one entry and deleted each receipt separately. The optimized queue case averages 6.97 entries per send and 9.91 receipts per delete. This directly verifies that ordinary API calls now amortize broker requests. + +For fanout, Foundatio averages 5.14 entries per publish and 6.48 receipts per delete, versus MassTransit's 7.63 and 7.81. That implies about 48% more publish requests and 21% more delete requests for equal work. This is evidence that batch utilization remains an optimization target; it does not isolate every source of the throughput gap. The next focused experiment should improve fanout batch collection without making fast handlers wait indefinitely for a slow handler, then confirm the result against live AWS. + +## Controlled arrival rates + +One thirty-second trial per cell, timestamped at the intended arrival schedule. All cases admitted their target rate to rounding; the acknowledgement denominator includes final drain.

Two retained durations fall less than 0.3 ms below their nominal boundaries. Both counts and actual elapsed times are retained; throughput uses actual elapsed time. LocalStack request logs include setup and cleanup; `confirmed-requests` omits warmup so measured input counts can be used to calculate messages per selected data-operation request. + +`analysis.json` contains medians, ranges, CPU, allocations, memory and totals per profile/variant.

Disposal drains admitted operations and cancels unfinished requests at the batch timeout. Missing or failed delete results never count as acknowledgements. The AWS receiver caps each pull at ten and overlaps up to four receive requests when consumer capacity permits. Receives share one slot budget and collect freed slots together, starting immediately when a batch fills. `MaxConcurrency` remains a strict bound on unacknowledged deliveries; a slow handler does not block unrelated slots.

A versioned `fnd.envelope` attribute carries the encoding, application ID, content type and headers. Headers are duplicated as native attributes only when selected in `AwsMessageTransportOptions.NativeMessageHeaders`, for SNS filters or external consumers. Select any required application headers (up to nine); the default empty list keeps the wire representation compact. For example, `NativeMessageHeaders = [KnownHeaders.MessageType, "tenant.id"]` exposes the type and tenant for SNS attribute filtering. Invalid or reserved attribute names fail during transport construction. The receiver accepts the earlier separate-attribute encoding, but earlier experimental receivers cannot read this new format. Upgrade producers and consumers together or use a new resource prefix. Existing experimental SNS attribute filters must explicitly select their header names; all consumer headers remain available without this option. These changes are confined to the unreleased provider. For long-lived contracts, register versioned wire names on producers and consumers: diff --git a/src/Foundatio.Aws/AwsMessageTransport.Batching.cs b/src/Foundatio.Aws/AwsMessageTransport.Batching.cs index f3e206107..684fde4c6 100644 --- a/src/Foundatio.Aws/AwsMessageTransport.Batching.cs +++ b/src/Foundatio.Aws/AwsMessageTransport.Batching.cs @@ -34,7 +34,7 @@ public async Task SendAsync(DestinationAddress destination, IReadOnl { results[index] = new SendItemResult { Index = index, Status = MessageSendStatus.NotAttempted }; var (body, encoding) = EncodeBody(messages[index]); - var attributes = BuildAttributes(messages[index], encoding, static value => value); + var attributes = BuildAttributes(messages[index], encoding); int bytes = Encoding.UTF8.GetByteCount(body); foreach (var pair in attributes) bytes = checked(bytes + Encoding.UTF8.GetByteCount(pair.Key) + Encoding.UTF8.GetByteCount(pair.Value) + 6); diff --git a/src/Foundatio.Aws/AwsMessageTransport.cs b/src/Foundatio.Aws/AwsMessageTransport.cs index 493c2c329..9cfe44f1e 100644 --- a/src/Foundatio.Aws/AwsMessageTransport.cs +++ b/src/Foundatio.Aws/AwsMessageTransport.cs @@ -38,14 +38,11 @@ public sealed partial class AwsMessageTransport : IMessageTransport, ISupportsPu private const string MessageIdAttributeName = "fnd.id"; private const string ContentTypeAttributeName = "fnd.content_type"; - // Well-known headers surfaced as native message attributes (in addition to the authoritative JSON blob) so brokers - // can filter/route on them — e.g. SNS subscription filter policies match on native attributes. - private static readonly string[] WellKnownNativeHeaders = [KnownHeaders.MessageType, KnownHeaders.Priority, KnownHeaders.CorrelationId]; - private static readonly IReadOnlySet _supportedRoles = new HashSet { DestinationRole.Queue, DestinationRole.Topic, DestinationRole.Subscription, DestinationRole.Binding }; private readonly AwsMessageTransportOptions _options; + private readonly string[] _nativeMessageHeaders; private readonly Lazy _sqs; private readonly Lazy _sns; private readonly ConcurrentDictionary _queueUrls = new(StringComparer.Ordinal); @@ -57,6 +54,7 @@ public AwsMessageTransport(AwsMessageTransportOptions options) { _options = options ?? throw new ArgumentNullException(nameof(options)); options.Validate(); + _nativeMessageHeaders = options.NativeMessageHeaders.ToArray(); _sqs = new Lazy(CreateSqsClient); _sns = new Lazy(CreateSnsClient); } @@ -584,19 +582,19 @@ private static bool IsTextContent(string? contentType) || contentType.StartsWith("text/", StringComparison.OrdinalIgnoreCase)); } - private static Dictionary BuildAttributes(TransportMessage message, string encoding, Func stringAttribute) + private Dictionary BuildAttributes(TransportMessage message, string encoding) { var headers = message.Headers; - var attributes = new Dictionary(StringComparer.Ordinal) + var attributes = new Dictionary(_nativeMessageHeaders.Length + 1, StringComparer.Ordinal) { - [EnvelopeAttributeName] = stringAttribute(JsonSerializer.Serialize(new AwsEnvelope(1, encoding, message.MessageId, message.ContentType, headers))) + [EnvelopeAttributeName] = JsonSerializer.Serialize(new AwsEnvelope(1, encoding, message.MessageId, message.ContentType, headers)) }; - foreach (string name in WellKnownNativeHeaders) + foreach (string name in _nativeMessageHeaders) { string? value = headers.GetValueOrDefault(name); if (!String.IsNullOrEmpty(value)) - attributes[name] = stringAttribute(value); + attributes[name] = value; } return attributes; diff --git a/src/Foundatio.Aws/AwsMessageTransportOptions.cs b/src/Foundatio.Aws/AwsMessageTransportOptions.cs index 79df2294a..76ef974ab 100644 --- a/src/Foundatio.Aws/AwsMessageTransportOptions.cs +++ b/src/Foundatio.Aws/AwsMessageTransportOptions.cs @@ -1,4 +1,5 @@ using System; +using System.Collections.Generic; using Amazon; using Amazon.Runtime; @@ -22,6 +23,12 @@ public class AwsMessageTransportOptions ///
