Hi everyone, I'm starting to look at how you might upgrade your cluster even if a major upgrade with non-passive API changes and do this all in uptime (i.e. do not read/write). I realize this may involve knowledge in how Kafka is used, in our case we own all the reading and writing for now.
Has anyone done this? What tools if any did you use? What was the general idea? If Kafka did make non-passive changes can we expect mirror maker or some migration tool equivalent? Has anyone tried the confluent REST proxy? Are there any clients for it? Adding or removing a broker from a cluster seems likely in this case. The re-assign partitions command seems like it can do it and may support generating the partition assignments via topics-to-move-json-file and broker-list options. Has anyone done this? Would this work for adding/removing brokers from a cluster? Bryan
