Revolutionizing Microservices Development with Helidon 4!
summary
Helidon 4 ships a new server called Helidon Nima built from scratch to run on Java 21 virtual threads, ditching the reactive callback stack and running straightforward blocking code while keeping Netty-level throughput. It shows a live demo starting 1 million threads without crashing, exposes HTTP/1.1, HTTP/2, gRPC and WebSocket, uses compile-time CDI and Helidon Builder, and compiles cleanly to GraalVM native images so synchronous programming gains the scalability of async systems.
