Hi, I am new to Zookeeper and have some doubts and hope to get answers from here: 1. what if the lead server is down, what's the backup strategy? does some random follower server become leader server automatically? 2. how much delay will the population of change from the leader server to the follower server? this is due to that the write operation only happens to the leader server and it will populate to the follower server by next state. I am just wondering what's the strategy of sync between leader server and follower server and how often it happens?
thanks! Guofu
