Should Restart celery beat after restart celery workers?

Question

i have two systemd service one handles my celery workers(10 queue for different tasks) and one handles celery beat

after deploying new code i restart celery worker service to get new tasks and update celery jobs

Should i restart celery beat with celery worker service too?

or it gets new tasks automatically ?

Answer 1

It depends on what type of scheduler you're using.

If it's default PersistentScheduler then yes, you need to restart beat daemon to allow it to pick up new configuration from the beat_schedule setting.

But if you're using something like django-celery-beat which allows managing periodic tasks at runtime then you don't have to restart celery beat.
