Interview with Chris Thalinger

GraalVM: Clearing up confusion around the term and why Twitter uses it in production

Maika Möbus

What does the “umbrella term” GraalVM stand for? We interviewed Chris Thalinger (Twitter) at JAX London 2019. Hear what he has to say about the meaning of Graal and how it can benefit Twitter as well as the environment.

Are you using Graal? If you are using Twitter, you probably are. As Chris Thalinger (Twitter) shared with us in an interview at JAX London after his talk:

“A lot of the Twitter infrastructure today, a lot of our microservices run 100% on Graal in production, so everything you tweet today is processed by, code-compiled by Graal.”

In the video, Chris explains what the confusion around the term GraalVM is all about, which different editions are available and why it’s being used at Twitter – and he touches on his keynote topic how Graal can be beneficial to the environment.

Chris Thalinger is a software engineer working on Java Virtual Machines for over 15 years. His main expertise is in compiler technology with Just-In-Time compilation in particular. Initially being involved with the CACAO and GNU Classpath projects, the focus shifted to OpenJDK as soon as Sun made the JDK open-source. Ever since Chris has worked on the HotSpot JVM at Sun, Oracle and now at Twitter.
