Celery's Gossip, Mingle and Heartbeat

ParthKolekar · February 6, 2020, 7:23pm

Hello!

I am running Sentry 9.12 with RabbitMQ and I am wondering if I can get rid of the Celery queues by disabling the features above by running

–without-gossip
–without-mingle
–without-heartbeat

options of Sentry workers respectively.

Will it cause any impact? Which of the options can I disable? What does Sentry use these Celery features for?

You can use —without-heartbeat and —without-gossip. If you add —without-mingle everything will break.

These defaults have changed for Sentry 10 and the flags don’t do anything anymore.

getsentry/sentry/blob/master/src/sentry/runner/commands/run.py#L210-L228


# These options are no longer used, but keeping around
# for backwards compatibility
for o in "without_gossip", "without_mingle", "without_heartbeat":
    options.pop(o, None)


from sentry.celery import app


with managed_bgtasks(role="worker"):
    worker = app.Worker(
        # NOTE: without_mingle breaks everything,
        # we can't get rid of this. Intentionally kept
        # here as a warning. Jobs will not process.
        # without_mingle=True,
        without_gossip=True,
        without_heartbeat=True,
        pool_cls="processes",
        **options
    )
    worker.start()
