GraalVM is a high-performance embeddable polyglot virtual machine capable of running different languages well: Java, Scala, Kotlin, JavaScript, Ruby, Python and everything with an LLVM backend like C and C++.

This session explores GraalVM and its uses for typical Java applications: getting the best peak performance on various workloads, creating native images for instant startup, mixing JavaScript and Python, or Ruby, or R into your code. You'll learn how to understand what the JIT compiler is doing with your code, how to collect the necessary debug information for further profiling, what are the limitations of GraalVM's native images and how to overcome most frequent of them.

We'll look at the polyglot applications and how they impact the code you're writing, learn the polyglot API you need to use to effectively mix different programming languages in one program. We'll explore using the common tooling like VisualVM and Chrome debugger for languages supported by GraalVM, even when you're running JavaScript as stored procedures in the database.

The session is based on a series of demos you can follow along and try yourself later, and the insight you can directly use.
