Subject [jira] [Created] (KAFKA-10530) kafka-streams-application-reset misses some internal topics
Date Mon, 28 Sep 2020 10:41:00 GMT
Oliver Weiler created KAFKA-10530:

             Summary: kafka-streams-application-reset misses some internal topics
                 Key: KAFKA-10530
                 URL: https://issues.apache.org/jira/browse/KAFKA-10530
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 2.6.0
            Reporter: Oliver Weiler

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

bbv4-indexer-717e6cc5-acb2-498d-9d08-4814aaa71c81-StreamThread-1-consumer bbv4-indexer-KTABLE-FK-JOIN-SUBSCRIPTION-RESPONSE-0000000014-topic

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).
