John Roesler commented on KAFKA-10530:
--------------------------------------

Thanks for the report [~oweiler] , and sorry for the trouble.

This report looks like https://issues.apache.org/jira/browse/KAFKA-9859, which should have been _fixed_ in 2.6.0. Can you confirm that you still see this issue in 2.6.0?

Thanks,

-John

> While the \{{kafka-streams-application-reset}} tool works in most cases, it misses some internal topics when using {{Foreign Key Table-Table Joins}}.
> After execution, there are still two internal topics left which were not deleted
> {code}
> bv4-indexer-KTABLE-FK-JOIN-SUBSCRIPTION-REGISTRATION-0000000006-topic
> bbv4-indexer-717e6cc5-acb2-498d-9d08-4814aaa71c81-StreamThread-1-consumer bbv4-indexer-KTABLE-FK-JOIN-SUBSCRIPTION-RESPONSE-0000000014-topic
> {code}
> The reason seems to be the {{StreamsResetter.isInternalTopic}} which requires the internal topic to end with {{-changelog}} or {{-repartition}} (which the mentioned topics don't).
