> Key: KAFKA-9913
> URL: https://issues.apache.org/jira/browse/KAFKA-9913
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Matthias J. Sax
> Assignee: Guozhang Wang
> Priority: Minor
> Labels: beginner, kip, newbie
>
> During the discussion of KIP-594, it became clear that it is helpful for
> testing purpose to verify which topics are used in a topology (ie, all user
> input and output topics, as well as internal topics like repartiton or
> changelog topics).
> While the current `TopologyDescription` does expose this information (only
> changelog topic names are missing atm), there is no convenient way to get all
> topic names at once, but one must traverse the nodes of each sub-topology to
> collect this information manually.
> Hence, the proposal is to add utility methods to `TopologyDescription` that
> expose this information programatically. As this is a public API change, it
> will be required to write a KIP
