Ismael Juma commented on KAFKA-1694:
------------------------------------
[~sslavic], `AdminUtils` is communicating with ZooKeeper directly. The broker
doesn't currently expose a protocol API that just checks if a topic exists. We
are currently planning to make `listTopics` more efficient, but no immediate
plans for a topic exists protocol API. Is there a use case where this is
important?
