The easiest way to fetch the topic metadata in my java app

Hi Team,

I would like to ask you about the easiest way to fetch topics metadata
from my app. My goal is monitoring of the topic size in my java app
(when I have also producers). Is there any API in Kafka libs for that? I
would like to avoid direct connection to the Zookeeper.

Thanks,
Chris

When you say "topic size", do you mean # of topics? If so, you can send
TopicMetadataRequest to any broker. See
https://cwiki.apache.org/confluence/display/KAFKA/0.8.0+SimpleConsumer+Examplefor
details. In particular, if the topic list in the request is empty, you
get all topics.

Thanks,

Jun
