Yuheng, kafka keeps cluster metadata in zookeeper along with topic metadata as well. You can use zookeeper-shell.sh or zkCli.sh to check zk nodes, /brokers/topics will give you the list of topics .

How does a server recover the topic's metadata and messages after restart and what data will be lost? Thanks for anyone to answer my questions. best, Yuheng
