Hi I’m looking at failing-over from one cluster to another, connected via mirror maker, where the __consumer_offsets topic is also mirrored.
In theory this should allow consumers to be restarted to point at the secondary cluster such that they resume from the same offset they reached in the primary cluster. Retries in MM will cause the offsets to diverge somewhat, which would in turn cause some reprocessing of messages on failover, but this should be a better option than resorting to the earliest/latest offset. Does anyone have experience doing this? Thanks Ben
