If anybody tries this out, please let us know. — Curious to learn why you would prefer BEAM API over KS native ones.

The recent 4.2 release is one of the largest milestones for Kafka Streams so far. The new “streams” groups introduce Kafka Streams specific RPCs into the protocol, making Kafka Streams more than just a wrapper around consumer/producer clients, and a first class citizen. \1

It’s also a release with major code changes for KS broker side, ie, adding task assignment logic to the group coordinator. While brokers did get smaller features for KS in the past, the only major feature designed with KS in mind in the past were transactions. \2

Curious to see where we will go next! In the meantime: checkout “streams” groups and let us know what you think!
