Woot, woot! 🎉 "Current San Francisco 2026: Your session has been accepted!" Excited to share the stage with @lucasbrut to talk about "Keeping the Balance with Kafka Streams" (KIP-1071), ie, how we are going to support warmup tasks and are building high-availability features.

After almost 12 years, I’ll be stepping back from my role at @confluentinc and handing over the reins to our Chief Product Officer @ShaunMClowes. Confluent was founded to change how companies use data, and against all odds, it has. And we’re not done! There is an ambitious roadmap for what’s next and I’ll watch from the sidelines with a lot of pride and a little FOMO as the team achieves that. I couldn’t be more grateful to all the customers who have built with us, investors who bet on us, and most of all to all the people who joined to do the hard work of making Confluent what it is. Thank you!

I second this, and in a positive way! It is super helpful on PR reviews, and I could file a bunch of new Jiras because of it.

Critical broker side fix for the new „streams“ groups. If you did hold back so far, it’s time to upgrade and adopt now!
