This module implements a simple queue.job
runner using ir.cron
triggers.
It's meant to be used on environments where the regular job runner can't
be run, like on Odoo.sh.
Unlike the regular job runner, where jobs are dispatched to the
HttpWorkers, jobs are processed on the CronWorker threads by the job
runner crons. This is a design decision because:
- Odoo.sh puts HttpWorkers to sleep when there's no network activity
- HttpWorkers are meant for traffic. Users shouldn't pay the price of
background tasks.
For now, it only implements the most basic features of the queue_job
runner, notably no channel capacity nor priorities. Please check the
ROADMAP for further details.
.. IMPORTANT::
This is an alpha version, the data model and design can change at any time without warning.
Only for development or testing purpose, do not use in production.

Configuration
Warning
Don't use this module if you're already running the regular
queue_job
runner.
For the easiest case, no configuration is required besides installing
the module.
To avoid CronWorker CPU timeout from abruptly stopping the job
processing cron, it's recommended to launch Odoo with
--limit-time-real-cron=0
, to disable the CronWorker timeout
altogether.
Note
In Odoo.sh, this is done by default.
Parallel execution of jobs can be achieved by leveraging multiple
ir.cron
records:
- Make sure you have enough CronWorkers available (Odoo CLI
--max-cron-threads
) - Duplicate the
queue_job_cron
cron record as many times as needed,
until you have as much records as cron workers.
Known issues / Roadmap
- Support channel capacity and priority. (See
_acquire_one_job
) - Gracefully handle CronWorker CPU timeouts. (See
_job_runner
) - Commit transaction after job state updated to started. (See
_process
)
