Hello, In a multi-broker Kafka 0.8.1.1 setup, I had one broker crashed. I restarted it after some noticeable time, so it started catching up the leader very intensively. During the replication, I see that the disk load on the ZK leader bursts abnormally, resulting in ZK performance degradation. What could cause that? How does Kafka use ZK during replication?
Thanks, Yury
