Subject [jira] [Created] (KAFKA-6435) Application Reset Tool might delete incorrect internal topics
Date Wed, 10 Jan 2018 01:26:00 GMT
Matthias J. Sax created KAFKA-6435:
--------------------------------------

             Summary: Application Reset Tool might delete incorrect internal topics
                 Key: KAFKA-6435
                 URL: https://issues.apache.org/jira/browse/KAFKA-6435
             Project: Kafka
          Issue Type: Bug
          Components: streams, tools
    Affects Versions: 1.0.0
            Reporter: Matthias J. Sax


The streams application reset tool, deletes all topic that start with {{<application.id>-}}.

If people have two versions of the same application and name them {{"app"}} and {{"app-v2"}},
resetting {{"app"}} would also delete the internal topics of {{"app-v2"}}.

We either need to disallow the dash in the application ID, or improve the topic identification
logic in the reset tool to fix this.
