GraalVM native image support #23

Open slinkydeveloper opened 1 year ago

slinkydeveloper commented 1 year ago

Check SDK compiles using GraalVM native image.

[ ] Figure out the required tasks required to enable the SDK to compile using GraalVM native image.
[ ] Add CI test checking GraalVM native image compilation.
[ ] Document how to build sdk-java with GraalVM native image (perhaps related to #22?)

A starting point here https://how-to.vertx.io/graal-native-image-howto/ and here https://graalvm.github.io/native-build-tools/latest/gradle-plugin.html

A blocker to support graalvm is the protobuf classes support: https://github.com/restatedev/sdk-java/issues/125. There's this tool we could try https://github.com/ricantech/protobuf-graalvm-feature

If we get rid of gRPC/Protobuf official libraries completely, we also solve this issue. To do so we would need just our code generator for services, and we could use https://github.com/HebiRobotics/QuickBuffers for the protobuf library.

For the time being this is not high priority. Lambda users can use Lambda ColdStart for JVM to get good startup time.
