Hi team, I can't find a template to ask general question so I just post it here, please direct me to the right template/place if I am wrong. 1. Kafka(<2.8) use ZK to do leader broker election, as far as I know, when doing rolling update, when the leader broker update, the kafka cluster needs to select a new leader. During the time, the whole cluster can't offer service(at least not for write). I searched some pages and found Pulsar also has a concept called leader broker, does that also happens in Pulsar? 2. It seems Pulsar use ZK a lot, e.g., store meta data such as topic/namespace/tenants information, does that affect the cluster performance when the cluster is large? The configuration rarely changes so I think that's OK, but the meta data such as consumer offset change frequently, so I guess ZK will be a bottleneck of the whole cluster?
