Summary

In this guide, GraalVM's AOT compilation is used to create native images for a Spring Boot application built with YugabyteDB's JDBC driver. This approach provides quicker startup times, on-demand horizontal scalability, less memory consumption, and better performance, making it suitable for cloud-scale applications. To get started, developers need to follow the prerequisites, including installing Gradle 7.5+, JDK 17+, and GraalVM 22.3.r17+. They can then use SDKMAN to install these dependencies and clone a sample repository that includes a simple JPA-based web application with CRUD functionality. The native build process requires more memory and takes longer than bytecode compilation, but it can be triggered using the `gradle nativeCompile` command. To overcome limitations in reachability metadata, developers can provide explicit runtime hints using annotations like `@ImportRuntimeHints`. The resulting native binary file can be run with the ysql profile to take advantage of the benefits of AOT compilation and GraalVM's native images.
