z4j-arq 1.7.0

z4j arq queue engine adapter (Apache 2.0)

z4j-arq

The arq engine adapter for z4j.

Streams every arq job lifecycle event from your async workers to the z4j and accepts operator control actions from the dashboard. Pair with z4j-arqcron to surface arq cron jobs.

Compatibility

• arq 0.26+ and <1 (capped below the eventual arq 1.0 breaking-major)
• Python 3.11+

What it ships

Capability	Notes
Job lifecycle events	in-progress, complete, failed
Job discovery	caller-supplied function-name list (arq has no auto-registry)
Submit / cancel	direct against the arq Redis pool
Reconcile task	via arq's Redis-backed result store

Async-native, uses arq's existing on_job_start / on_job_end hooks.

Not yet supported (the brain greys these actions out): retry-by-id, bulk retry, and purge queue. arq exposes no job-enumeration, dead-letter, or re-enqueue-by-id primitive, so these are deferred rather than shipped.

Install

pip install z4j-arq z4j-arqcron

Pair with a framework adapter (FastAPI is the most common pairing for arq):

pip install z4j-fastapi z4j-arq z4j-arqcron
pip install z4j-bare    z4j-arq z4j-arqcron   # framework-free worker

Pairs with

• z4j-arqcron, schedule adapter for arq cron jobs

Reliability

• No exception from the adapter ever propagates back into arq's worker loop or your job code.
• Events buffer locally when z4j is unreachable; workers never block on network I/O.
