---------------------------------
Thanks all for the input, and thanks for pushing this along [~bchen225242]. Yes
I think what you've said makes sense and I'll start drafting a KIP
> 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
> Assignee: Joel Wee
> Priority: Major
> Labels: bug, help-wanted, newbie
>
> 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.
