[jira] [Created] (KAFKA-7930) StreamsResetter makes "changelog" topic naming assumptions

Murad M created KAFKA-7930:
------------------------------

             Summary: StreamsResetter makes "changelog" topic naming assumptions
                 Key: KAFKA-7930
                 URL: https://issues.apache.org/jira/browse/KAFKA-7930
             Project: Kafka
          Issue Type: Improvement
          Components: streams, tools
    Affects Versions: 2.1.0
            Reporter: Murad M


StreamsResetter deletes the topics considered internal. Currently it just checks the naming as per [code|https://github.com/apache/kafka/blob/1aae604861068bb7337d4972c9dcc0c0a99c374d/core/src/main/scala/kafka/tools/StreamsResetter.java#L660]. If assumption is wrong (either topic prefix or suffix), tool becomes useless if aware even dangerous if not. Probably better either:
 * naming assumption should be optional and supply internal topics with argument (--internal-topics)
 * deletion could be optional (--no-delete-internal)
