Squeezing out what today's hardware is capable of requires designing around it from scratch. @laserdatainc's @spetzu explains how they did that in #Rustlang during a highly technical #P99CONF talk. Don't miss this one, it's free! ow.ly/zT6h50ZZ132

And it's only going to get even better! :)
We've been cooking. Multi-leader clustering is coming to Apache Iggy, with every node leading its own partitions.
3-node cluster at 800 MB/s: p999 down 93% replicated, 87% persisted, +42% producer throughput.

The #p99conf swag passed its stress test. No regressions. But a few milliseconds in the streaming layer can haunt your whole stack.
Next week at @P99CONF, I'll show how we built @ApacheIggy in Rust to keep tail latencies in check.
More p99+ improvements coming. See you online!

New on the blog: part 2 of 3 on Apache Iggy clustering. What happens when the primary dies: electing a successor without losing a committed write, bringing a node back, and real failover numbers.

Step by step, Iggy is becoming a bit more viral :)
Jordan Epstein: Ouch, you didn’t like my name? 🥲
I thought I had a pretty cool one!
Iggy = Italian Greyhound. One of the fastest dogs in the world. 🐕⚡
Fast dog. Fast streaming engine. Now does the name make a little more sense? 😄

That moment when the biggest names in message streaming start trying to recruit members of the @ApacheIggy team :)
This one made me smile. 🙂
Interesting to see @ApacheIggy contributors/engineers being approached to help “shape the future of Kafka.” Meanwhile, the Iggy community is busy refining what the future of message streaming engines should look like.
Rust. Modern I/O. Predictable tail latency. Multi-protocol by design. Developer experience from day one.
All respect to Kafka and everything it has done for distributed systems and data streaming. And inspiring us in many ways!
Back to building!

The first Apache Iggy community meetup is this Wednesday, 7 October at 16:00 UTC, live on Google Meet and open to everyone.
A talk on clustering, then a fireside chat with the maintainers. Bring your questions!

Apache Iggy just hit 5000 stars on GitHub! Thank you to our 140+ contributors and everyone who starred, built, and contributed.

Zapraszam już za tydzień na @4Developers w Katowicach, gdzie podzielę się doświadczeniami i dobrymi praktykami, dotyczącymi tworzenia wysoce wydajnych systemów na przykładzie @ApacheIggy :)

New on the blog: part 1 of 3 on how Apache Iggy became a cluster. Why Viewstamped Replication Revisited over Raft, one VSR group per partition, how we swapped the whole server, and what it costs, with benchmarks.

In the last few weeks, @ApacheIggy became a TLP, clustering shipped, and @laserdatainc Cloud went GA.
Time for a quick recharge, then back to building new features and pushing more optimizations :)
Our biggest, and probably most important, release is finally here!
Apache Iggy 0.9.0 is out, our first release as a Top-Level Project! ⚡
Clustering has landed. Powered by Viewstamped Replication Revisited (VSR). 600+ PRs. 60 contributors, 34 of them new. Message streaming at laser speed, now highly available.

Our new platform for the real-time streaming and agent data infrastructure is almost ready!
One more stream is here. 💚
Today marks the beginning of a new chapter for @laserdatainc
We’re bringing together three worlds that have largely evolved independently:
1. Real-time message streaming.
2. Agent Data Fabric.
3. Real-time applications.
One infrastructure. One durable foundation.
Today we’re announcing major new capabilities across the stack, from VSR-based clustering in @ApacheIggy and Agent Data Exchange (AGDX) Protocol for agent-agent-system data exchange, to new LaserData Cloud plans (launch, scale, performance, and enterprise) and deployment options across AWS and GCP.
All these capabilities are in PRIVATE BETA, will be GA on September 18, 2026.
And we’re just getting started.
We’ll continue shipping throughout the year. But once in a while, we’ll take a moment to bring together the biggest ideas we’ve been working on and share where we’re taking real-time and agent data infrastructure next.
Welcome to the next chapter of LaserData. 🚀

We’re pleased to announce two new projects graduated to Top-Level Project status. buff.ly/Jx10VbW
@ApacheIggy, a hyper-efficient, persistent message streaming platform written in Rust
Apache Sourcelume, open source instrumentation for AI training-data provenance.

Undeniably my biggest open-source achievement.
Apache Iggy™ began as a side project I hoped to finish in 3 weeks. Now, it is an Apache Software Foundation Top-Level Project.
Grateful to every friend, colleague, and contributor who made it possible.
A dream come true. ❤️
Apache Iggy™ has graduated from the Apache Incubator and is now a Top-Level Project! 🎓⚡
120+ contributors. 4.5K+ stars. 500K+ downloads. Message streaming at laser speed.

Please welcome Chengxi Luo as a new Apache Iggy committer! Contributions across the Go SDK - BDD framework, leader redirection, binary reader/writer, and the publish workflow.

Hope to see you at P99 CONF, where I'll talk about the architecture and performance optimizations in @ApacheIggy
In high-performance distributed systems, every delay at the message streaming layer compounds. During @laserdatainc's @spetzu's #P99CONF talk, you'll see how they built Apache Iggy in #Rustlang. Don't miss this highly technical session! ow.ly/gL8650Zsmyw
