GraalVM native images explained

on YouTube ↗31m

" summary

GraalVM’s native-image compiles Java ahead-of-time into a standalone ELF binary by analyzing reachable classes, snapshotting the heap with SubstrateVM under the closed-world assumption, and producing small binaries (hello-world ≈ 2.6–8 MB) that start in milliseconds (example web app responds in ~70 CPU ms) and use only a few megabytes of RAM. Dynamic features need config: use the autoconfiguration agent to record reflective/proxy usage into JSON or build with no-fallback to catch missing config.
