Hello, I've been experimenting with mirror maker and am a bit confused about some behavior I'm seeing.
I have two simple single broker clusters setup locally, source and target. The source cluster has a topic foo with a few message in it. When I run mirror maker with --whitelist '*' (as noted in the documentation), nothing is written to the target cluster. Switching '.*' makes no difference. With --whitelist '\w*', everything is mirrored, including __consumer_offsets. With --whitelist foo, the foo topic is mirrored correctly from source to target. With --whitelist 'foo|bar' (where foo already exists and bar does not yet), foo is mirrored correctly, but bar is ignored when it gets created. Restarting mirror maker with the same command causes it to pick up on bar. I assume there is some outdated documentation around old vs new consumer in mirror maker, but it's still not obvious how to automatically mirror all non-internal topics. Any pointers would be appreciated. Thanks, Luke
