Managing Celery Task Results

Question

I am pretty new to Celery and I thought I had read somewhere that the task results only stay around for a limited time. However my backend (redis) is getting pretty bloated after running a lot of tasks through it.

Is there a way to set a TTL on task results or is this something I need to manually purge (and how)?

Answer 1

According to the celery documentation you can completely ignore all results using CELERY_IGNORE_RESULT .

You can also expire results after a set amount of time using CELERY_TASK_RESULT_EXPIRES , which defaults to 1 day. In the notes it says this should just work with the redis backend, whereas some of the other backends require celery beat to be running.

There is also the CELERY_MAX_CACHED_RESULTS setting that caches up to 5,000 results by default.
