nexus-queue

Portable worker runtime for the Nexus-Queue standard: taskiq + Redis Streams, domain-agnostic, ports-and-adapters. One project builds queues the same way as the next, and a worker's handlers move between projects unchanged.

What this package owns (the parts that are the same across projects):

Namespaced streams — nq:{project}:{queue} (+ :cg, :dlq) and nq:{project}:status, so multiple projects/queues coexist on one Redis (the default global "taskiq" stream is never used).
Versioned envelope — standard labels (nq_v, nq_task, nq_tenant, nq_idem, nq_trace, nq_enqueued_at, nq_priority) on top of taskiq's message, plus typed pydantic payloads.
Ports — JobStatePort, BlobStorePort, IndexPort, StatusEventPort. Handlers depend only on these; each project supplies the adapters (e.g. Payload vs Postgres/MinIO).
Middleware stack (broker-level): idempotency (dedup on nq_idem), DLQ (dead-letter on retry-exhaustion instead of silent drop), retries with exponential backoff + jitter, OTel tracing (nq_trace propagation), and Prometheus metrics.
Producer + kicker — a Python Publisher and a generic HTTP kicker for non-Python producers. The TypeScript producer client ships as @zetesis/nexus-queue.

Spec: nexus-queue-spec.md.

Released via release-please on every conventional commit to main (scope nexus-queue).
