dear Kafka users, I have some questions regarding decommissioning kafka broker node and replacing it with the new one. Lets say that we have three broker nodes and each topic in Kafka has replication factor = 3, we upgrade one node with the following steps : 1. add one broker node to cluster 2. shutdown old broker node
My questions are 1. When we add one new broker to the cluster will it trigger Kafka topic / group leadership rebalance? 2. Is there any way to disable the to-be-decommissioned node to hold no topic/group leadership (acting as passive copy) so that it can be decommissioned with minimal effect to Kafka clients? Thank you, -- Muqtafi Akhmad Software Engineer Traveloka
