Embracing Virtual Threads

on YouTube ↗14m

" summary

Helidon 4.4 (Apr 2026) abandons its Netty-based async core and rewrote web server to a virtual-thread model, allocating one virtual thread per request so handlers can block safely; results are higher throughput, predictable latency and “no drama” scaling. 4.4 adds LangChain for J integration with blocking Java streams and Agentic support, targets Java 26, uses compile-time annotations that generate source, and expresses intent to move Helidon to OpenJDK.
