GoKawiilApache Iggy, Rust-based message streaming project, becomes Apache Top-Level Project
Apache Iggy, an open-source message streaming platform written in Rust, has graduated from the Apache Incubator to become a full Apache Software Foundation Top-Level Project after a unanimous vote on August 19, 2026. The project began in March 2023 as founder Piotr Gankiewicz's personal effort to learn Rust and study messaging internals, later evolving into a thread-per-core system using io_uring and Viewstamped Replication for consensus, achieving single-digit millisecond P99 latencies.
GoKawiil's interpretation of the reporting above, not reported fact.
Reaching TLP status signals that Iggy has built a diverse, sustainable contributor base beyond its original creator, meeting the Apache Foundation's governance and community standards. It also adds a new, performance-focused Rust alternative to the crowded message streaming space long dominated by tools like Apache Kafka, potentially appealing to engineers prioritizing low latency and operational simplicity.
- Apache Iggy graduated from incubation to Top-Level Project status on August 19, 2026.
- The project moved from incubator entry to graduation in about 18 months.
- Iggy uses a thread-per-core architecture, io_uring, and Viewstamped Replication for high-performance streaming.
Programming Rust, 2nd Edition (O'Reilly) — Apache Iggy began as one engineer's project to finally learn Rust for real, and this O'Reilly book is a classic path to doing the same. It digs into ownership, concurrency and performance - exactly the areas that make Rust attractive for building fast message streaming systems.
