Aeron 1.52.0: container-aware CPU affinity, debug log rotation, a new LogInspector CLI, and lower latency in replay workloads. See what changed.

Discover how Aeron’s new Persistent Subscriptions let late‑joiners switch seamlessly between replay and live streams over UDP or IPC, add automatic slow‑consumer recovery via a clean API, and match ReplayMerge latency with only a modest memory increase.

Aeron 1.51.0 adds a new feature sponsored by Nonco, which is included in the open source version: Persistent Subscriptions, for seamless live/historical streams. This release also includes new C/C++ client APIs for async control, and stricter protocol and cluster reliability.

Adaptive today announces it is developing Aeron Sequencer, a software infrastructure platform designed to tackle the most persistent challenges in modern trading system development: consistency, scalability, performance, and availability.

Aeron’s latest release enhances trading technology’s performance and observability. With new IPC support for response channels, async counter creation, and improved client identification, capital markets can now achieve even greater speed, reliability, and transparency in their trading systems.

Learn about Publication Revoke for immediate stream cleanup, Image Reject for dynamic resource control, and new mechanisms to prevent dormant client interference. Full C/C++ archive client API parity is now also available. Explore new premium tools and see what’s on the roadmap.

Here are some of the highlights: Aeron v.1.48.0 offers immediate resource release, session rejection, improved client connections, GA status for response channels and C/C++ APIs, per-stream NAK counters, and various enhancements.

Discover Aeron Archive client enhancement and stability improvements, Aeron Cluster multi-service messaging fixes and standby snapshot handling, NAK message logging, address re-resolution and more.

Aeron 1.46.0, Agrona 1.23.0, and SBE 1.33.0 now require a minimum of JDK 17 to compile and run, discontinuing support for JDK 8 and 11. This update ensures compatibility with modern build tools and dependencies, aligning with the broader Java ecosystem’s shift away from older JDK versions.

Prevent resource exhaustion via per stream session limits, automate group behavior settings for efficient nakking, improve visibility and debugging with detailed Archive logging, SBE DTO generation and more.
