Episode notes
Fast Native Compilation For Spring Apps
- GraalVM now compiles Spring applications to native images in about 30 seconds, improving startup and memory footprint significantly.
- Thomas Wuerthinger says these improvements are practical and reduce development hurdles for production use.
Single-Process Python And Java Integration
- GraalVM runs Python and Java in the same process with the same VM, threads, and heap for uniform execution.
- Thomas claims this yields faster, more secure, and self-contained deployments than separate Python services.
WebAssembly Target For Spring Native Images
- Native Image can target machine code or WebAssembly, enabling Spring apps to run in browsers and Node.js.
- Thomas frames this as protecting developer investment by providing multiple target architectures.
