We are happy to share that the Apache Kafka 4.1.1 bug-fix release is now available! It contains a critical memory-leak fix for #KafkaStreams and many other fixes. For details see kafka.apache.org/blog#apache_... Thanks to 32 contributors and Lianet Magrans as our RM.

#ApacheKafka did grow up over the years, and conference talks changed accordingly... -- If you like to nerd out, "The Kafka Protocol Destructed" talk by Mateo Rojas from LittleHorse is a refreshing change back to the roots! current.confluent.io/post-confere...

Repeat after me: Kafka TX timeout is not a producer liveness check, but a guard against head of line blocking for read-committed consumers.

Including “Strengthening Kafka Streams Operations and Observability” — If you are using #KafkaStreams on Confluent Cloud you should check out the announcement.

#KafkaStreams is at the core of Metronome. "There is some talks we've given[...] on what it looks like to run KS at scale." -- "We are storing TBs of state in RocksDB." A very advanced deployment requiring careful engineering. But the library approach shines! Check it out. cnfl.io/3WPoAGE

I've built a Core Insights dashboard for #Kafka Streams! 📊 This Prometheus-based Grafana dashboard brings together the metrics that actually matter. One view to spot issues before they become incidents. #dataengineering kafkastreamsfieldguide.com/articles/kaf...

Also congrats to our friends from Michelin. Excited to see their DLQ feature for #KafkaStreams being included in the upcoming #ApacheKafka 4.2.0 release. #Current #DataStreamingAwards current.confluent.io/data-streami...

Data Streaming Awards at #Current „…Kafka Streams where reliability matters the most“ Congrats Raft!

Calling database nerds in SF! I'm covering SlateDB at the systems meetup next Wednesday (10/29). If you're around, I'd love to meet you in person (that way you'll have proof I'm not just an AI bot). 👉 luma.com/e7feg2i6

Happy to share, that we did release an update to our @kafkastreams.bsky.social UI in #ConfluentCloud. We are now showing more detailed information about instances, threads, running/rebalancing state, and JMX metrics. Check it out and let us know what you think! www.confluent.io/blog/monitor...

I've just published the 92nd edition of my Kafka Monthly Digest! It covers the 4.1.0 release, as well as progress on 4.0.1 and 4.2.0. I also covers new KIPs, recent community releases and blog posts. developers.redhat.com/blog/2025/10...

Any KIP-1071 experience out there? Asking for a friend.

I hate it when @kafkastreams.bsky.social ships with a memory leak. I hate it even more, if I am the offender…

Know someone who’s always answering questions, sharing code, mentoring, or pushing Apache Kafka® and Apache Flink® forward? That sounds like a Confluent Community Catalyst to us. Nominate them or yourself by September 1 → cnfl.io/45pZGRO

I loving working with the #ApacheKafka community! (Step 1) A person asks a question on Confluent Community Slack, and it sounds like a serious issue, so we ask them to file a Jira ticket. \1

While we are waiting for Apache Kafka 4.1.0 release, the development does not stop. We just completed KIP-1034 (cwiki.apache.org/confluence/d...) which adds a DLQ feature to Kafka Streams. Very exciting!

Praise in public, criticize in private.
