Piotr Nowojski commented on FLINK-15143:
----------------------------------------
We probably need both a mention in the release notes (release notes field of
some relevant Jira ticket) and somewhere in the documentation (some performance
tuning section?).

> In release 1.10, with FLIP-49, we introduced significant changes to the
> TaskExecutor memory model and it's related configuration options / logics.
> It is very important that we clearly state the changes and potential effects,
> and guide our users to tune their clusters with the new configuration for
> both new setups and migrations of previous setups. And we should do that for
> both documentation and the release note.
