Andrey Zagrebin closed FLINK-14898.
-----------------------------------
Release Note: The background cleanup of the expired state with TTL is now
activated by default if it is supported by the configured state backend.
Resolution: Done
[~klion26] Thanks!
[~liyu] sure, I thought we would have another PR here for the translation but
another issue also makes sense then I am closing this with the release note

> So far, we were conservative about enabling background cleanup strategies for
> state with TTL. In general, if state is configured to have TTL, most users
> would expect the background cleanup to kick in. As there were no reported
> issues so far since the release of backend specific cleanups and that should
> not affect any state without TTL, this issue suggests to enable default
> background cleanup for backends.
