Greetings, We have 8 nodes Brokers setup on AWS in 2 availability zones with 2 replication. Our plan is to add one more node and distribute 3 nodes in each AZ and change replication factor to 3.
In order to replicate data in each AZ we need to enable Rack awareness. Can someone guide how can I achieve this ? I can bring down only one broker and if I change settings in one broker i.e. (put broker.rack=rackid) and restart the Kafka then what would be impact ? how it will handle with the requests because other brokers have not these settings yet. Also, we have 1000+ topics in our cluster , do we need to manually reassign partitions for all topics ? I have searched everywhere but couldn't find any place where it says if can do it while kafka cluster is in operation. I really appreciate if someone can help on this. -- Regard Ashu
