Hi, I have two questions regarding the kafka broker setup. 1. Assuming i have a 4-broker and 2-zookeeper (running in quorum mode) setup, if topicA-partition0 has the leader set to broker4, can I change the leader to other broker without killing the current leader?
2. What is the latency of switching to a different leader when the current leader is down? Do we configure it using the consumer property - refresh.leader.backoff.ms 3. What is the best practice of dynamically adding a new node to a kafka cluster? Should i bring up the node, and then increase the replication factor for the existing topic(s)? thanks in advance, Cal
