> Allow users to cleanup internal data
> ------------------------------------
>
> Key: KAFKA-3185
> URL: https://issues.apache.org/jira/browse/KAFKA-3185
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: Guozhang Wang
> Assignee: Matthias J. Sax
> Priority: Blocker
> Labels: user-experience
> Fix For: 0.10.0.1
>
>
> Currently the internal data is managed completely by Kafka Streams framework
> and users cannot clean them up actively. This results in a bad out-of-the-box
> user experience especially for running demo programs since it results
> internal data (changelog topics, RocksDB files, etc) that need to be cleaned
> manually. It will be better to add a
> {code}
> KafkaStreams.cleanup()
> {code}
> function call to clean up these internal data programmatically.
