Bring the Action: Using GraalVM in Production
summary
GraalVM runs as a drop-in JDK or compiles apps ahead-of-time with native-image; a Spring Boot dictionary demo compiles with the GraalVM Maven plugin, finds 33k reachable types, 187k methods, and turns a 2.4s start into 2.4s → 148ms startup. Benchmarks show JVM at 56k vs 46k vs 60k RPS (openJDK, native-image, optimized native), typical memory wins of 3–5×, small container images (example 18MB), tooling for hints/agents, Spring AOT integration and Micrometer traces all working in the demos.
