-------------------------------------
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
{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).
