z4j-dramatiq 1.1.2

z4j Dramatiq queue engine adapter (Apache 2.0)

z4j-dramatiq

License: Apache 2.0 Status: v1.0.0 - first public release alongside z4j-celery and z4j-rq.

The Dramatiq queue-engine adapter for z4j. Drop into any Dramatiq install (Redis OR RabbitMQ broker - both first-class on day 1) and z4j observes every actor your workers run via the canonical Dramatiq middleware chain - no monkey-patches, no subclassing, no host code changes.

Install

# Redis broker
pip install z4j[dramatiq] dramatiq[redis]
# OR RabbitMQ broker
pip install z4j[dramatiq] dramatiq[rabbitmq]

# Or just this package:
pip install z4j-dramatiq

What it ships on day 1

Capability	Status	Notes
Event capture (received / started / succeeded / failed)	✅	Z4JMiddleware in your broker chain - blessed observability hook
Discovery	✅	Walks broker.actors
retry	✅	Re-sends the actor's message
cancel	⚠️	Promoted into capabilities iff Abortable middleware is installed
purge_queue	✅	With confirm-token + Z4J_PURGE_THRESHOLD guard
Dual-broker (Redis + RabbitMQ)	✅	Both natively supported, both in CI

What it deliberately does NOT ship

Capability	Why
bulk_retry	Deferred to v1.1
requeue_dead_letter	Deferred to v1.1 (Dramatiq has DeadLetter middleware)
rate_limit	Deferred to v1.1 (Dramatiq has Throttler middleware)
restart_worker	Dramatiq workers expose no remote-control channel - never
pool grow / shrink / consumer ops	Dramatiq has no pool concept - never

The adapter advertises only what it implements via capabilities() - the dashboard hides every button it can't honor. The cancel button only appears if Abortable is in your middleware stack.

Scheduler pairing

Dramatiq has no built-in scheduler; use z4j-apscheduler to surface APScheduler-driven periodic / cron jobs on the Schedules page.
