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) andnq:{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_tracepropagation), and Prometheus metrics. - Producer + kicker — a Python
Publisherand a generic HTTP kicker for non-Python producers. The TypeScript producer client ships as@zetesis/nexus-queue.
