Once KIP-500 is enabled, we will deprecate `broker.id` so that `node.id` is the only ID going forward. That said, I'm trying to give us a little wiggle room by defining this config as internal for now. So we still have an opportunity to change this. If you have any thoughts about it, definitely share them. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
