> In Kafka Streams we need to dynamically create or update those internal topics (i.e.
repartition topics) upon rebalance, inside {{InternalTopicManager}} which is triggered by
{{StreamPartitionAssignor}}. Currently we are using {{ZkClient}} to talk to ZK directly for
such actions.
> With create and delete topics request merged in by [~granthenke] as part of KIP-4, we
should now be able to remove the ZkClient dependency and directly use these requests.
