Abstract: What the Crac - Superfast JVM Startup (OpenJDK)
In a world where microservices are more and more a standard architecture for Java-based applications running in the cloud, the JVM warmup time can become a limitation. Especially when you look at spinning up new instances of an app as a response to changes in load, the warmup time can be a problem. Native images are one solution to solve these problems because their statically ahead-of-time compiled code simply doesn’t have to warm up and so has a short startup time. But even with the shorter startup time and smaller footprint, it doesn’t come without a drawback. The overall performance might be slower because of the missing JIT optimizations at runtime. There is a new OpenJDK project called CRaC (Coordinated Restore at Checkpoint) whose goal is to address the JVM warmup problem with a different approach. The idea is to take a snapshot of the running JVM, store it in files and restore the JVM at a later point in time (or even on another machine). This session will give you a short overview of the CRaC project and shows some results from a proof-of-concept implementation.
