Hi all, According to https://issues.apache.org/jira/browse/KAFKA-1229, there is currently no support and no reason to support dynamic configuration changes for Kafka servers that are already running. I just wanted to solidify my understanding of how configs would then be changed, specifically:
If i wanted to change configs on a running cluster (say log retention) but I do not want unavailability for that cluster at any time, would the right way of changing the configs be: 1) Alter the config file 2) Bring down the leader broker using a controlled shutdown, letting replicas handle the load while the leader is down 3) Restart the leader broker with new configs, using preferred leader assignment to have it resume control Would I also need to bring down the in sync replicas and reboot them too?
