Building High Performance Microservices for Java with Micronaut & GraalVM

on YouTube ↗53m

" summary

Shows how Micronaut + GraalVM native image compiles a Micronaut app into a native executable using Gradle, removes dead code, and avoids runtime reflection by generating DI and repository code at compile time. Demo builds a REST + JDBC app, runs Flyway migrations against Oracle Autonomous Database, and produces an executable that starts in ~9s and uses ~84MB (jar was ~270MB). Everything compiles and the native binary runs and passes tests.
