>                 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.
