Netflix' Practice vs OpenJDK's Theory” [I/O]

A podcast episode recorded at JavaOne 2026 features Netflix Senior Performance Engineer Martin Chalupa and OpenJDK Project Leyden lead John Rose discussing ahead-of-time (AOT) caching in Java. They cover how training runs populate AOT caches to speed up class loading, linking, profile gathering, and eventually JIT compilation. Netflix's approach uses canary deployments of new versions to gather training data and build caches for the rest of their fleet. The conversation touches on time scales, checkpointing, and how to manage and inspect cache files.
