Micronaut AOT: Optimizing Your Applications for the JIT and GraalVM
summary
Micronaut AOT is an extension to the Micronaut framework that precomputes at packaging time information normally discovered at runtime, improving startup and runtime performance for both JVM JIT and GraalVM native images. It converts resources like YAML configuration into Java configuration and optimizes class loading (e.g., service loader) to avoid runtime parsing and reflection. The talk demonstrates using Micronaut AOT to make traditional Micronaut microservices and GraalVM native binaries start extremely fast (examples target sub-10ms startup).
