How do people handle situations, and specifically the broker.id property,
where the Kafka (broker) cluster is not fully defined right away?
Here's the use case we have at Sematext:
* Our software ships as a VM
* All components run in this single VM, including 1 Kafka broker
* Of course, this is just for a nice OOTB experience, but to scale one
needs to have more instances of this VM, including more Kafka brokers
* *One can clone our VM and launch N instances of it, but because we have a
single Kafka broker config with a single broker.id <http://broker.id>
it, one can't just launch more of these VMs and expect to see more Kafka
brokers join the cluster. One would have to change the broker.id
on each new VM instance.*
How do others handle this in a software that is packages and ships to user
and is not in your direct control to allow you to edit configs?
Would it be best to have a script that connect to ZooKeeper to get the list
of all existing brokers and their IDs and then generate a new distinct ID +
config for the new Kafka broker?
Or are there slicker ways to do this that people use?
