管理芹菜任务结果(Managing Celery Task Results)

管理芹菜任务结果(Managing Celery Task Results)

我对Celery来说很新，我以为我已经读过某个地方，任务结果只能在有限的时间内保持不变。 然而，在通过它执行大量任务后，我的后端（redis）变得非常臃肿。

有没有办法在任务结果上设置TTL，还是我需要手动清除（以及如何）？

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)?

根据celery文档，您可以使用CELERY_IGNORE_RESULT完全忽略所有结果。

您还可以使用CELERY_TASK_RESULT_EXPIRES在一段时间后使结果到期，默认为1天。 它说这应该只适用于redis后端，而其他一些后端需要celery beat才能运行。

还有CELERY_MAX_CACHED_RESULTS设置，默认情况下最多可缓存5,000个结果。

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.
