-----------------------------------------------------------
[~ptmagic] please hold on a moment. As the main contributor of limiting RocksDB
memory usage, I know this is not a issue which would only change a default
value. We should also tell users some information about how to tuning and how
to add extra buffer space. Even though we do not add related documentation in
the end within the PR for this issue, we should also take them into
consideration.

> Key: FLINK-15692
> URL: https://issues.apache.org/jira/browse/FLINK-15692
> Project: Flink
> Issue Type: Task
> Components: Runtime / State Backends
> Affects Versions: 1.10.0
> Reporter: Till Rohrmann
> Priority: Blocker
> Fix For: 1.10.0

>
> Enable limiting RocksDB memory consumption by default. This means to change
> the default value of {{state.backend.rocksdb.memory.managed}} to {{true}}.
> This will change Flink's default behaviour for many users but I believe the
> benefits of a much more predictable memory behaviour of Flink will outweigh
> the downside of having fewer memory available.
