Micronaut, the ultra-light JVM framework of the future
summary
Micronaut is a JVM framework that achieves very fast startup (~1 s) and a small memory footprint (~10 MB) by performing dependency injection and configuration at compile time and avoiding runtime reflection. The talk demonstrates building a HelloWorld and a Twitter crawler in Kotlin/Java using Netty HTTP, a reactive MongoDB client, validation, metrics and tests that load the full app in milliseconds, and shows deployments to App Engine, Docker, and a GraalVM native-image that starts in ~30 ms.
