> Auto infer external topic partitions in stream reset tool
> ---------------------------------------------------------

> Key: KAFKA-9042
> URL: https://issues.apache.org/jira/browse/KAFKA-9042
> Project: Kafka
> Issue Type: Improvement
> Components: streams, tools
> Reporter: Boyang Chen
> Assignee: highluck
> Priority: Major
> Labels: needs-kip, newbie, newbie++
>
> As of today, user has to specify `--input-topic` in the stream reset to be
> able to reset offset to a specific position. For a stream job with multiple
> external topics that needs to be purged, users usually don't want to name all
> the topics in order to reset the offsets. It's really painful to look through
> the entire topology to make sure we purge all the committed offsets.
> We could add a config `--reset-all-external-topics` to the reset tool such
> that when enabled, we could delete offsets for all involved topics. The topic
> metadata could be acquired by issuing a `DescribeGroup` request from admin
> client, which is stored in the member subscription information.
