Ashish K Singh commented on KAFKA-2275:
---------------------------------------
[~guozhang] if you agree with the approach of extending existing partitionsFor
API, instead of creating a new ListTopics() API, then we should update the JIRA
title accordingly. Thoughts?
> Add a ListTopics() API to the new consumer

> With regex subscription like
> {code}
> consumer.subscribe("topic*")
> {code}
> The partition assignment is automatically done at the Kafka side, while there
> are some use cases where consumers want regex subscriptions but not
> Kafka-side partition assignment, rather with their own specific partition
> assignment. With ListTopics() they can periodically check for topic list
> changes and specifically subscribe to the partitions of the new topics.
> For implementation, it involves sending a TopicMetadataRequest to a random
> broker and parse the response.
