From Java to a Native Executable: How GraalVM and Quarkus Change the Game

on YouTube ↗48m

" summary

Demonstrates building a Java web app with Quarkus and GraalVM: a demo to‑do app uses Hibernate ORM with Panache and Quarkus extensions for JDBC Postgres, OpenAPI/Swagger and testing. Shows live-reload that recompiles and restarts handlers in ~100–165 ms, GraalVM native-image builds in ~2–3 minutes and native startup in ~0.05–0.25 s, with memory usage reduced to around 10% of a full HotSpot JVM improving container density.
