[jira] [Commented] (KAFKA-12766) Consider Disabling WAL-related Options in RocksDB

["Bruno Cadonna (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-12766?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17341782#comment-17341782 ] 

Bruno Cadonna commented on KAFKA-12766:
---------------------------------------

I think throwing an exception is too harsh. Additionally, I do not understand how we should disable the option since we do not have control over the `Options` object. I think, if we want to do something about it, ignoring is the best solution. But I am also fine with not doing anything, because Streams disables the WAL anyways.

> 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.
