Hello Folks, I wish to contribute to Kafka internals. And, one of the things which can help me do that is understanding how kafka uses zookeeper. I have some of these basic doubts:-
1. Is zookeeper primarily used for locking ? If yes, in what cases and what kind of nodes does it use - sequential/ephemeral? 2. Does kafka use zookeeper watches for any of functions ? 3. What kind of state is stored in Zookeeper ? (I believe it has to be the leader information per partition, but is there anything apart from it?) What is the scale of data that is stored in Zookeeper ? Looking forward for your help. Thanks, prabcs
