Create a Java Native Image using GraalVM

torrespro commented 4 years ago

Native image provides a way to build and run Spring Boot applications with different characteristics than a regular JVM deployment:

The output is a native executable that contains your application with a subset of the JDK and the dependencies required to run it.
In practice the executable would likely be shipped in an highly optimized container image (FROM scratch Docker image is supported) with reduced surface attack which is good fit with Kubernetes.
Startup time is almost instant and peak performance is available immediately, allowing support for scale-to-zero (serverless) applications including for regular Spring Boot web applications.
Memory consumption is reduced, which is a good fit for systems split into multiple microservices.

With Spring Boot 3 and Spring Framework 6, the native compilation is included into core. I plan to try adding Java Native Image creation after we upgrade SSDK to version 16.x.x.

Although nice to start looking at native, the golden sample services are meant to be setting an example of how to build services in Backbase. Currently, in Backbase, native is not used and introducing it here might confuse engineers looking at the golden sample as an example to copy.

Thanks. I will "try adding Java Native Image creation" in an experimental branch only.
