Hi, I am using ZooKeeper service for leader election and group management. I have read in the site ( http://hadoop.apache.org/zookeeper/docs/r3.2.2/recipes.html#sc_leaderElection) under the "LeaderElection" section that, if all the clients try to access the getChildren() when trying to become a leader, it causes a bottleneck on the server. But, I wanted to execute getChildren() method on all the clients that have seen a change on the parent's ZNode. So, could you please tell what could be the maximum number of clients that can be used without any performance drop on the server, when all the clients try to execute getChildren() method? Currently, I intend to use 16 clients cluster, and the data on each of the ZNodes is very less (say < 500 bytes).
Anxiously waiting for your reply, Thanks & Regards, Srikanth.
