Matthias J. Sax resolved KAFKA-9859.
------------------------------------
Resolution: Not A Problem
> kafka-streams-application-reset tool doesn't take into account topics
> generated by KTable foreign key join operation
> --------------------------------------------------------------------------------------------------------------------
>
> Key: KAFKA-9859
> URL: https://issues.apache.org/jira/browse/KAFKA-9859
> Project: Kafka
> Issue Type: Bug
> Components: streams, tools
> Reporter: Levani Kokhreidze
> Priority: Major
>
> Steps to reproduce:
> * Create Kafka Streams application which uses foreign key join operation
> * Stop Kafka streams application
> * Perform `kafka-topics-list` and verify that foreign key operation internal
> topics are generated
> * Use `kafka-streams-application-reset` to perform the cleanup of your kafka
> streams application: `kafka-streams-application-reset --application-id
> <your_app_id> --input-topics <your_input_topic> --bootstrap-servers
> <your_bootstrap_server> --to-datetime 2019-04-13T00:00:00.000`
> * Perform `kafka-topics-list` again, you'll see that topics generated by the
> foreign key operation are still there.
> `kafka-streams-application-reset` uses `repartition` and `changelog` suffixes
> to determine which topics needs to be deleted, as a result topics generated
> by the foreign key are ignored.
