Cloud Native apps with Micronaut 4 and GraalVM
summary
Micronaut 4 + GraalVM claim: move framework work to compile time so apps avoid reflection, cut runtime size and start dramatically faster. Demos use Gradle, Micronaut Data, Micronaut Serialization (replacing Jackson), RxJava3 streaming file upload of multi‑GB files, and Gradle-native builds into Docker. Results shown: zero reflective caches, app runtimes ~11 MB vs ~30 MB, Jackson 2.4 MB vs Micronaut 400 KB, thousands of functional tests (≈4,000) run in ~15 minutes, and native startup ~10 ms — native builds are slower to produce but worked in demos.
