Hey, all. Is there any general guidance around using mirrored topics in the context of a cluster migration?
We're moving operations from one data center to another, and we want to stream mirrored data from the old cluster to the new, migrate consumers, then migrate producers. Our basic question is whether it's safe for us to commingle mirrored and directly-produced data in the same topic, even serially. In other words, is the following procedure safe? Why or why not? - Data is produced to topic T on cluster A - Topic T is mirrored to cluster B - Consumers run against T on cluster B - Producers gradually migrate from A to B We've found the following, which seems to suggest no, but doesn't address the point directly: http://events.linuxfoundation.org/sites/events/files/slides/Kafka%20At%20Scale.pdf -- Jack Foy <j...@hiya.com>
