Helidon Nima - Loom based microservices framework

on YouTube ↗36m

" summary

Helidon Nima is a new microservices framework built atop JDK Loom virtual threads and a custom Nima server module; it claims comparable or better throughput than Helidon SE/reactive and native servers (benchmarks on an i9 Linux box show Nima slightly above native for plain text/JSON and roughly 2x throughput for Helidon MP when swapped to Nima). It supports HTTP/1.1 (pipeline), HTTP/2 work-in-progress, websockets prototype, testing hooks and observability (OpenTelemetry), and demonstrates synchronous blocking code that debugs normally while remaining high‑concurrency and performant.
