All versions

v0.14.1

What’s Changed

Improvements

  • Adapter conformance suite: StateConformanceFixture now propagates generateId and generateInvalidId through to the cases. Previously the runner only forwarded stateAdapter and poisonTransaction, so adapters configured with a custom validateId could not exercise the caller-supplied id path in conformance tests.

Breaking Changes (testing helpers only)

  • Removed StateAdapterConformanceContext and NotifyAdapterConformanceContext types. Callers writing conformance suites for external adapters (e.g. it.extend<NotifyAdapterConformanceContext>(...) in vitest specs) should switch to StateConformanceFixture / NotifyConformanceFixture. No runtime API changes — this only affects adapter authors using the conformance harness.

v0.15.0

What’s Changed

Breaking Changes

  • triggerJob/triggerJobs renamed to rescheduleJob/rescheduleJobs with an optional schedule parameter ({ at: Date } | { afterMs: number }). Omitting it reschedules to now (previous behavior). A past time clamps to now. Only pending jobs are reschedulable. Batch validation is atomic.
  • Error classes renamed: JobNotTriggerableError / JobsNotTriggerableError → JobNotReschedulableError / JobsNotReschedulableError. New batch error variants JobsNotFoundError and JobsNotReschedulableError for rescheduleJobs. The status property removed from the singular error; the batch variant exposes jobIds.
  • Observability event renamed: jobTriggered → jobRescheduled. Now also emitted on worker retry (not just client reschedules), making it the single signal for “scheduledAt changed.” jobAttemptFailed is now a pure failure event — rescheduledAt/rescheduledAfterMs removed. scheduleAfterMs dropped from jobCreated and jobRescheduled events.
  • StateProvider gains required transactionConcurrency field ("concurrent" | "serialized"). Custom provider authors must declare it.
  • Dashboard: POST /jobs/:id/trigger renamed to /reschedule; “Trigger now” button renamed to “Reschedule”.
  • OTEL: Counter queuert.job.triggered → queuert.job.rescheduled; log entry job_triggered → job_rescheduled.

Features

  • Blocker chain cap: A job can declare at most 100 blocker chains. startChain, startChains, and continueWith throw the new BlockerLimitExceededError when exceeded.
  • Dashboard UX improvements: Infinite scroll on list views (chains, jobs, chain detail), real links on cards (right-click/Cmd-click to open in new tab), and smart back navigation that preserves filters.

Bug Fixes

  • createProcessors type resolution: Previously resolved job type names from the local slice only; now resolves from all registered slices.
  • "incomplete" dedup scope: Multi-step chains that continued past the root job are now correctly matched. Previously, once the root completed, the chain was no longer matched even though it was still running.
  • Concurrent unblock race (@queuert/postgres, @queuert/sqlite): Row-level locks on blocked jobs during unblockJobs prevent a race where concurrent blocker completions could leave dependent jobs stranded in blocked status. job_blocker PK widened to support duplicate chain IDs.

Performance

  • Autovacuum tuning (@queuert/postgres): New migration pins autovacuum_vacuum_threshold = 5000 / scale_factor = 0 on job and job_blocker tables, replacing size-proportional 0.02. Gives predictable vacuum cadence regardless of table size.

v0.15.1

What’s Changed

Bug Fixes

  • Saturated workers no longer busy-loop. A worker whose slots were all busy kept polling getNextJobAvailableInMs as fast as the event loop allowed: with a due job in the backlog the poll reported 0ms, so the wait returned immediately and the worker re-entered the loop without being able to take the work. Saturated in-process workers now wait for a slot to free (or for pollIntervalMs) instead of polling.

Performance

  • Postgres job acquisition now uses the acquisition index. acquireJob and getNextJobAvailableInMs matched jobs with type_name IN (...) ordered by scheduled_at, which Postgres cannot satisfy from the (type_name, scheduled_at) index for more than one job type — it fell back to scanning and sorting the entire pending backlog on every acquisition and every poll. Both queries are now per-job-type LATERAL lookups, turning a backlog scan into one index lookup per job type. Workers polling a large Postgres backlog should see a substantial drop in database load.
  • On Postgres, when several job types are polled together, acquisition now picks a job type at random and takes its oldest due job rather than always taking the globally oldest job. This keeps a backlogged job type from starving the others.
  • Postgres getNextJobAvailableInMs no longer takes row locks on jobs scheduled in the future.

v0.16.0 Latest

What’s Changed

Queuert 0.16 rebuilds the job model around the chain’s head row and reworks attempt handling around a single finish outcome API, with a one-step schema migration from v0.15.1. It also brings faster listing queries, a redesigned dashboard, and a leaner, more consistent public API. This release contains many breaking changes — review the notes below before upgrading.

Breaking Changes

  • New job model — a chain’s head row is now the chain itself. ChainStatus is just running | completed; completed jobs carry continuedToId; running jobs expose attemptAt / attemptBy / attemptUntil. “Lease” is renamed to “attempt” throughout (leaseConfig → attemptConfig with timeoutMs / heartbeatMs, LeaseConfig → AttemptConfig, plus matching log events and metrics).
  • Attempt finalization — handlers end an attempt with complete(async ({ finish }) => finish({ output | continueWith | reschedule })). rescheduleJob() and RescheduleJobError are removed; rescheduling is now a non-error outcome. completeChain’s complete option is renamed to handler.
  • Renames — startChain / startChains → createChain / createChains.
  • Listing API reshaped — flat options with a single status, required typeName, status-dependent orderBy checked at compile time, root → independent; the chainId / jobId / chainTypeName filters are removed; CreatedAtCursor → TimestampWithIdCursor.
  • Deduplication — scope is now required and "incomplete" is renamed to "running" (missing or unknown scopes throw TypeError). windowMs and excludeChainIds are removed.
  • Caller-supplied id collisions now throw instead of being silently ignored.
  • cascade removed from deleteChain / deleteChains.
  • TransactionContextRequiredError removed — a plain Error is thrown instead.
  • wrapHandler now wraps the whole attempt, so a catch around next() observes handler failures.
  • Public type exports pruned — internal helper types are no longer exported; CompletedJob and AttemptConfig are newly exported.

Database Migrations (@queuert/postgres, @queuert/sqlite)

  • All migrations are collapsed into 001_initial_schema. You must be on v0.15.1 before upgrading.
  • PostgreSQL: the upgrade copies tables while v0.15.1 workers keep running; a migration_lock table makes concurrent migrateToLatest() calls safe.
  • SQLite: stop all workers and clients before running the migration.
  • vacuum() is removed, along with SQLite’s checkForeignKeys / checkAutoVacuum options.

Features

  • step transaction primitive inside attempt handlers, with a matching wrapStep middleware hook.
  • Batched lookups — getChains / getJobs, with ChainTypeMismatchError.
  • Type names & counts — listChainTypeNames / listJobTypeNames and countByChainTypeNames / countByJobTypeNames.
  • Worker shutdown signal — in-flight handlers receive "worker_stopping" as the abort reason when the worker stops.

Dashboard

  • Full UI redesign: Overview page, Find by ID (⌘K), status tabs, and themes.
  • New endpoints for type names, counts, and by-ID lookups. Malformed IDs and unknown /api paths return 404; uncaught errors return 500 with an { error } body.

Observability (@queuert/otel)

  • Attempt spans record an abort event; prepare / step / complete spans record exceptions and ERROR status.
  • Breaking: blocker-completion span renamed resolve chain.* → complete chain.*; queuert.attempt.result attribute removed (read the outcome from span status); metric names follow the lease → attempt rename.
  • @opentelemetry/api peer dependency now also accepts ^1.0.0.

Performance & Fixes

  • Faster listing queries via per-type anchoring.
  • PostgreSQL and SQLite skip the redundant RELEASE SAVEPOINT round-trip.
  • Type checking is roughly 20–40% cheaper.
  • AttemptMiddleware typed against a concrete adapter now works.
  • chain.input now correctly reflects the entry job’s input.
  • Fixed a race where a job created with blockers could start pending instead of blocked (#4).
