We are heavy users of RocksDB and have had several issues with memory
managed in Kubernetes, most of them actually went away when we upgraded
from Flink 1.9 to 1.13.
Do we know why there's such a huge performance regression? Can we improve
this somehow with some flag tweaking? It would be great if

That's actually also what I'm seeing most of the time and what I'd expect to
improve with the newer RocksDB version.
Hence, I'd also favour the upgrade even if there is a slight catch with
respect to performance - we should, however, continue to investigate this
together with the RocksDB communi
For the details of what causes this regression, I would add @Yun Tang
to this discussion.

I am hearing quite often from users who are struggling to manage memory
usage, and these are all users using RocksDB. While I don't know for
certain that RocksDB is the cause in every case, from my perspective,
getting the better memory stability of version 6.20 in place is critical.
