Stevo Slavic commented on KAFKA-1694:
-------------------------------------
Here's one use case: with auto topic creation disabled, when trying to publish
with KafkaProducer to a topic that doesn't exist, one will get a timeout back -
only way to differentiate is the timeout caused by topic does not exist
condition or any other issue I do now by issuing topicExists check as followup
to failed on timeout publish request.
Since auto topic creation can be disabled, all CRUD operations should be
supported as minimum through client APIs. Yes, this kind of check can already
be done with list support and in memory exist check. I see topicExists check as
an optimization. With lots of topics, it's handy to have this optimization
available in Kafka's Java client APIs, and should be easy to support so please
consider adding it to Broker API and Java client.
