“The source code is the new bytecode” Interesting read. linkedin.com/pulse/i-told-r…

Releases, releases, releases… and KIPs!

Checkout the docs (#streams-rebalance-protocol" target="_blank" rel="nofollow noopener">docs.confluent.io/cloud/current/…) and kick the tires, and let us know what you think.

With the recent #ApacheKafka 4.2 release, the new "streams" rebalance protocol is production ready. It's exciting that it's also GA on Confluent Cloud now. The cherry-on-top is, that our #KafkaStreams Cloud UI now also shows task assignment information for "streams" groups. \1

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

We are happy to announce Apache Kafka 4.2.0! Highlights are: Queues for Kafka and the new #KafkaStreams "streams" groups. Thanks to all the 155 contributors and our RM @christo_lolov More details on the web page: kafka.apache.org/blog/2026/01/1…

@coltmcnealy 5!

I just asked my team "how much AI is used in this workflow." It's happened, I'm officially an executive 🥲

@coltmcnealy It’s called marketing.

How could AI replace software? AI **IS** software.

Four ongoing #ApacheKafka releases at the same time. Unheard from what I can remember!

Great episode with @BleeGoldman! Well, I didn’t expect it to be anything else than outstanding! youtu.be/QEZILs_qk8Y

In case you missed it. The eagle has landed… cwiki.apache.org/confluence/dis…

@lenadroid Yes! Totally. Just at the very end it got too fast for me. My excuse: not a native speaker (but I guess it’s really just an excuse)

@MatthiasJSax I just smiled wider and wider as it's speeding up, so addicting

I got lost at the end… but very interesting.
