Shit, wait, there's documentaton for Mirror Maker 2 now? I spent most of my time implementing it by reading hypothetical examples in a KIP, and then diving into the actual code.

Hardly the most straightforward, and it was rather a gaping hole. Thanks for the background on how that hole developed.

I really appreciate Confluent putting that time into documenting something vital, that could compete with your own product, and IMO that does put a nail in the previous commenter's assertions about Confluent's alleged attempts to wall off necessary features of Kafka.
