-------------------------------------
Hi [~roman] , I checked the code and not find no-op changelogStorage. If I
understand correctly, changelogStorage will always be created whether or not
changelog is enabled. Can you confirm that ?
> Allow to configure Changelog Storage per program

> URL: https://issues.apache.org/jira/browse/FLINK-26372
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Configuration, Runtime / State Backends
> Affects Versions: 1.15.0
> Reporter: Roman Khachatryan
> Assignee: Feifan Wang
> Priority: Major
> Fix For: 1.16.0

>
> It's currently possible to override state.backend.changelog.enabled per job,
> but it's not possible to override Changelog storage settings (i.e. writer
> settings).
> There should be 1) an API and 2) runtime support for that.
