---------------------------------------
Hi [~TomerWizman]!
Thank you for your interest!
Since Streams disables the WAL and it will also log a warn message that the WAL
is disabled and the WAL-related options are ignored, I would say that it
shouldn't be too unexpected for users not getting the set WAL-related options.
I would keep it simple and just ignore the set WAL-related options and state in
the warn log message that they were ignored.
Looking forward to your PR!

> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Bruno Cadonna
> Assignee: Tomer Wizman
> Priority: Minor
> Labels: newbie, newbie++
> Fix For: 3.1.0
>
>
> Streams disables the write-ahead log (WAL) provided by RocksDB since it
> replicates the data in changelog topics. Hence, it does not make much sense
> to set WAL-related configs for RocksDB instances within Streams.
> Streams could:
> - disable WAL-related options
> - ignore WAL-related options
> - throw an exception when a WAL-related option is set.
