I would like to revive an older thread around auto generating broker ID. As a AWS user, I would like Kafka to just use the instance's ID or instance's IP or instance's internal domain (whichever is easier). This would mean I can easily clone from a AMI to launch kafka instances without having to worry about setting a unique broker ID. This also alows me to setup auto scaling.
I realize 1 size may not fit all in this case. Other strategies that may work for other cloud providers are generate the UUID and persist it on a disk, etc. What I propose is a way to define a a broker ID generation strategy in the configuration file which points to a class file that is responsible for generating the ID. Is this something being already worked upon?
