Building Optimized Java Microservices with Micronaut 4 & GraalVM

on YouTube ↗49m

" summary

Micronaut 4 plus GraalVM Native Image produces smaller, faster Java services with JDK 17 baseline and official support for GraalVM 23 and initial virtual threads integration so blocking code can scale on lightweight threads. The framework shifts work to a compile step with compilation-time checking (no runtime reflection), Micronaut Data validates queries at compile time, the demo shows test containers start once (first run ~16 seconds) then tests run nearly instantly in continuous mode.
