Hi ZooKeeper users, I am playing currently with zookeeper and testing what happens if the leader of an ensemble goes down. I know that during the leader election zookeeper server won't reply to any requests and if leader election takes a long time than existing sessions might expire. What I see in my tests that each server reads the last snapshot file to get last zxid for leader election and when the leader is elected than the leader reads the snapshot again before it syncs the followers.
This means that the more data we store in zookeeper the longer it takes to elect a new leader. This is also means as load of the ensemble increases clients need bigger session timeout to "survive" the loss of the leader. Is it possible to do anything about this and have a fast leader election even if the snapshot is big? Regards, Botond Hejj
