> KIP-800 is adding a new "reason" parameter to the Consumer#enforceRebalance API, which will be passed in to a new field of the JoinGroup protocol. We invoke this API throughout Streams for various reasons, which are very useful for debugging the cause of rebalancing. Passing in the reason to this new API would make it possible to figure out why a Streams client triggered a rebalance from the broker logs, which are often the only logs available when the client logs cannot be retrieved for whatever reason
