z4j-arqcron 1.4.0

z4j scheduler adapter for arq cron jobs (Apache 2.0)

z4j-arqcron

The arq cron-jobs scheduler adapter for z4j.

Surfaces every cron job your arq Settings class registers on the dashboard's Schedules page, read, enable, disable, trigger.

What it ships

Capability	Notes
List schedules	every cron_jobs entry on your arq Settings
Read	by registered name
Enable / disable	via consumer-side gating
Trigger now	enqueues the task immediately, outside the schedule
Boot inventory	full snapshot at agent connect; existing cron jobs show up without editing

arq cron jobs are defined declaratively on the WorkerSettings class, so create / update / delete are intentionally out of scope, those need a deploy round-trip. The dashboard hides buttons it can't honor.

Install

pip install z4j-arq z4j-arqcron

from arq import cron
from z4j_bare import install_agent
from z4j_arq import ArqEngineAdapter
from z4j_arqcron import ArqCronAdapter

class WorkerSettings:
    redis_settings = ...
    cron_jobs = [
        cron(cleanup, minute=set(range(0, 60, 5))),
    ]

install_agent(
    engines=[ArqEngineAdapter(settings=WorkerSettings)],
    schedulers=[ArqCronAdapter(settings=WorkerSettings)],
    brain_url="https://brain.example.com",
    token="z4j_agent_...",
    project_id="my-project",
)

Pairs with

• z4j-arq, engine adapter

Reliability

• No exception from the adapter ever propagates back into arq's worker loop or your job code.
• The cron-jobs registry is read-only at runtime; the adapter only observes, it does not rewrite WorkerSettings.
