Quarkus and GraalVM: booting Hibernate at supersonic speed, subatomic size

on YouTube ↗51m

" summary

Quarkus combines GraalVM native-image and build-time analysis to shrink and preinit a Java app so it boots in milliseconds and uses tiny RSS, but it requires adapting libraries and registering reflective access. Demo compiles Hibernate, JDBC drivers and app enhancements into a native binary that boots in 6 ms (another example ~14 ms) and runs with about 13 MB RSS (Quarkus on HotSpot ~74 MB), while the native build is heavy (recorded ~12m38s) yet produces a working, fast executable.
