Way to check existence of topic

[SasakiKai <le...@icloud.com>]

Hi, all.

I have a simple question. 
Is there anyway to check existence of some topic from consumer? I want to implement a consumer which checks before consuming messages efficiently. Has this type of API already been implemented? Or if you have any plan, please let me know.

Thank you

Take a look at the entry point
https://github.com/apache/kafka/blob/0.8.1/core/src/main/scala/kafka/admin/TopicCommand.scala#L32
behind kafka-topics.sh --describe --topic for how to-do that now .

We are working on a new CLI and Shell for that
https://issues.apache.org/jira/browse/KAFKA-1694 moving this to the server
side with wire protocol calls and client wrappers of them to-do moving
forward
