The Next Generation of the Consumer Rebalance Protocol is here—KIP-848 is now live in Confluent Cloud!
This protocol, first available in #ApacheKafka 4.0, transforms consumer group rebalances by shifting to a server-driven, incremental approach. That means:
⏱️ No more stop-the-world rebalances and minimal downtime
📈 Greater stability and scalability, especially with large consumer groups
🔧 Simplified configuration and enhanced monitoring
Want the full breakdown?
Learn all about KIP-848 on our blog: confluent.io/blog/kip-848-co…
Just merged my 400th commit to @apachekafka! From my first patch in 2015 to today, it’s been an incredible journey. Grateful to contribute to such a vibrant, impactful open source community. Here’s to many more!

Proud to have contributed formal verification (TLA+) for three key improvements in Kafka 4.0:
✅ KIP-966: Strengthens the replication protocol.
✅ KIP-996: Introduces PreVote for more stable KRaft leadership.
✅ KIP-848: Delivers more efficient, predictable rebalancing.

.@ApacheKafka 4.0 significantly streamlines the platform by replacing ZooKeeper with KRaft for default metadata management.

And the old group coordinator implementation is gone from Apache Kafka - love it when open-source projects can delete large chunks of complex code.

Apache Kafka 4.0 is OUT.
and Zookeeper is OUT (of Kafka).
KRaft is the default in Kafka now and a bunch of other improvements and features.
My favourite is Queuing support in Kafka. 🚀 I have missed this feature a lot, which has resulted in complexity, because queuing semantics are powerful for many applications and having it within Kafka gets rid of one additional dependency.
I did a podcast with @davidjacot on #kafka internals and it is one of the most viewed episodes on The GeekNarrator. We talked about how Zookeeper becomes a bottleneck and how KRaft solves it. Give it a watch if you want to learn deep Kafka internals. Link below 👇

The difference between Kafka 4.0 and 3.0 will be awesome:
- No ZooKeeper
- Tiered Storage
- New Rebalance Protocol (848)
- EOS support in Connect
- State Updater Thread in Streams
- Improved Txn Protocol (890)
- Custom Stream Task Assignment (924)
#apachekafka is on a roll!

1/ There is a mini open source drama, this time because RedPanda, a company with a source-available Apache Kafka clone, bought an open source connector framework and made licensing and trademark changes to thwart other startup competition. (a thread) news.ycombinator.com/item?id…

I just published edition 71 of my Kafka Monthly Digest. It covers the recent releases, KIPs, community projects and blogs.
Also as is customary, I review some of the milestones the #ApacheKafka project achieved in 2023 and make some predictions for 2024!

Our #ApacheKafka streaming infrastructure served 29 million messages per second at peak. That’s 45% growth from 2022 – and we did it more efficiently this year with 14% fewer brokers.
