Subject Re: Kafka running on AWS - how to retain broker.id on new instance spun-up in-place of instance/broker failed
Date Wed, 14 Nov 2018 19:30:01 GMT
EBS is one of the option. But we use instance level storage where we loose
all data as soon as we have a broker failed in AWS.

In such scenario, anyone has better launch script or cofiguration can be
executed on new broker to retain the old id not conflicting with existing
broker ids.
