Matthias J. Sax commented on KAFKA-5386:
----------------------------------------
Understood. Technically, it would be possible to allow users to create
changelog topic manually. But there are some strings attached. But we got the
issues with naming conventions multiple times already. Maybe we need to do
something about it. If you want to work on this, we would be more than happy.
However, this change would require a KIP:

Let us know if you need any help preparing a KIP in case you want to pick it
up. We can also discuss a little more on this JIRA. \cc [~miguno] [~guozhang]

> [Kafka Streams] - custom name for state-store change-log topic
> --------------------------------------------------------------
>
> Key: KAFKA-5386
> URL: https://issues.apache.org/jira/browse/KAFKA-5386
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Affects Versions: 0.10.2.1
> Reporter: Bart Vercammen
> Labels: needs-kip
>
> 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?
