---------------------------------------

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!

> 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.
