Hello Everyone, Apache Iggy (Incubating) version *0.7.0* has been released.
Apache Iggy (Incubating) is a high-performance, persistent message streaming platform written in Rust, powered by a next-generation io_uring, thread-per-core, shared-nothing architecture that delivers ultra-low latency and millions-per-second throughput. It supports QUIC, TCP, WebSocket, and HTTP transports and includes growing ecosystem integrations such as Iceberg, Elasticsearch, and Flink. Iggy also provides production-ready SDKs across all major languages like Rust, C++, C#, Java, Node.js, Python, Go, Elixir etc. The *0.7.0 release <https://iggy.apache.org/blogs/2026/02/24/release-0.7.0/>* represents a major evolution of Apache Iggy: - Advances the distributed systems foundations introduced in 0.6.0 <https://github.com/apache/iggy/releases/tag/server-0.6.0>, strengthening the *Viewstamped Replication (VSR) implementation* with deterministic tick-based timeouts, new replication primitives, view-change handling, partition traits, and a metadata state machine with snapshot support. - *Operational resilience and performance* are further improved with an *embedded Web UI *enabled by default, NUMA-aware execution, enhanced async disk I/O handling, graceful shard shutdown safeguards, and stronger critical task failure management. - *Observability and integrations continue to mature* with Prometheus metrics for connectors, improved HTTP configuration with retry logic, enhanced PostgreSQL source and sink plugins, and continued evolution of the unified connector runtime. - *SDK ergonomics *are upgraded across the ecosystem, including a fluent builder API in Java, async iterator support in Python consumers, leader redirection improvements in Go, expanded C# APIs with .NET 10 support, and broader testing and serialization enhancements. - The release also *upgrades the Rust toolchain*, expands ARM64 and Linux builds, strengthens CI workflows and automated publishing, and *increases API and integration test coverage* — further hardening Apache Iggy for large-scale, production environments. - Read the 0.7.0 blog post <https://iggy.apache.org/blogs/2026/02/24/release-0.7.0/> for more details. We'd like to express our gratitude to all contributors to this release, as well as to the mentors and incubator for their invaluable support. *Artifacts* are available on *Downloads* page: https://iggy.apache.org/downloads *Release Notes:* https://github.com/apache/iggy/releases/tag/server-0.7.0 *New Committer* We're thrilled to welcome Łukasz Zborek <https://github.com/lukaszzborek>as a new Apache Iggy committer! Łukasz has been a core contributor to our C# SDK and is the #8 contributor in our repository. His work goes far beyond building a top-notch C# SDK — he has helped find and fix issues across many areas of the project. His contributions span CI, BDD testing, core features like TLS support, reconnection handling, and the high-level consumer/publisher APIs. Congratulations, Łukasz! We are eager to expand our community and extend an invitation to new contributors. We genuinely welcome the opportunity to collaborate with individuals who share our passion and expertise. *Website*: https://iggy.apache.org *Repository*: https://github.com/apache/iggy *Discussions*: https://github.com/apache/iggy/discussions *Issue tracker*: https://github.com/apache/iggy/issues *Mailing list*: https://lists.apache.org/[email protected] *Discord channel*: https://discord.gg/apache-iggy *Blogs* https://iggy.apache.org/blogs/ We care so deeply about performance & efficiencies, and so benchmarks are first-class citizen for us, read more about our approach for benchmarks https://iggy.apache.org/blogs/2025/02/17/transparent-benchmarks Community published benchmarks are uploaded to https://benchmarks.iggy.apache.org Best, Apache Iggy (Incubating) Community
