>    Affects Versions: 0.10.2.1

> Currently, when working with Kafka backed state stores in Kafka Streams, these log compacted topics are given a hardcoded name :  _my.app.id-storename-changelog_
> {noformat}    public static String storeChangelogTopic(String applicationId, String storeName) {
>         return applicationId + "-" + storeName + STATE_CHANGELOG_TOPIC_SUFFIX;
>     }{noformat}
> It would be nice if somehow I would be able to override this functionality and provide the topic-name myself when creating the state-store.
> Any comments?
> Would it be OK to submit a PR for this?
