### AI overview

Episode 70 of the Inside Java Podcast discusses ahead-of-time caching for Java applications. The episode covers how training runs populate a cache that can reduce JVM startup work in production, along with Netflix's canary-deployment approach for collecting training data and creating caches for later deployments.

### Source excerpt

From time scales to checkpointing, from managing to inspecting cache files, there are a number of details to consider when creating AOT caches for faster Java application launches.

### AI overview

This tutorial explains how to use Ahead-of-Time cache features in recent JDK releases to improve Java application startup time and warm-up performance. It covers the train, assemble, and run workflow introduced in JDK 24 and method profiling improvements in JDK 25.

### Source excerpt

As the year comes to a close, turn your focus to boosting your Java application performance by applying Ahead-of-Time (AOT) cache features in recent JDK releases. This article guides you through using AOT cache optimizations in your application, thereby minimizing startup time and achieving faster peak performance. What is the Ahead-of-time cache in the jdk [...] The post Run Into the New Year with Java's Ahead-of-Time Cache Features appeared first on JVM Advent.
