Building Optimized Java Microservices with Micronaut 3 & GraalVM

on YouTube ↗42m

" summary

Demonstrates building a Java REST microservice with Micronaut 3 and Micronaut Data JDBC using Java 17 records, H2 in-memory DB and Gradle, then compiling to a GraalVM Native Image. Claims include 37 ms startup and ~17 MB memory for the native binary. Shows compile-time checks (no runtime reflection), generated repository queries, runnable JAR and Docker packaging, and that native image build produces a small, fast executable suitable for serverless, IoT, and low-memory containers.
