Subject Re: Is there a way to pull out kafka metadata from zookeeper?
Date Fri, 11 Oct 2013 18:30:36 GMT
Thanks guys!
But I feel weird. Assume I have 20 brokers for 10 different topics with 2
partitions and  2 replicas for each. For each consumer consumes different
topic/replica I have to specify those 20 brokers and go over all of them to
know which broker is alive. And even worse how about I dynamically add new
broker into the cluster and remove the old one. I think it's nice to have a
way to get metadata from zookeeper(centralized coordinator?) directly.

Best,
Siyuan
