I'm having a @kafkastreams.bsky.social theme at #Current26, so I'm kicking things off with a talk about record headers in Kafka Streams state stores
Continuing the rebalancing theme at #Current26, with a talk on the challenges of large rebalances in Kafka Streams and moving to KIP-1071 based rebalances
Another Kafka Streams talk at #Current26, this time from Michelin around KS automatic resource naming and all the "fun" that comes from that
Last breakout session of #Current26 is sticking with my Kafka Streams theme, a walkthrough of designing a production grade application based on Kafka Streams
Great comparison of „classic“ and „streams“ rebalancing. Pretty much sums it up.
Did you know that we released a skill for building @kafkastreams.bsky.social applications? Check it out and let us know about your experience using it. github.com/confluentinc...

10 years ago, I was opening his first PR to Apache Kafka github.com/apache/kafka... I clearly had no idea what I was getting myself into!

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
