There’s a time when you need to call some R script from Quarkus. One option is to create microservice, but what if it’s something really small and you just want to call it in a single place without overwhelming project architecture. This is where GraalVM comes in. With GraalVm you can execute R scripts directly from Java without any conversion, microservices, or endpoints. We already have seen an example in Python, let’s see how to do it in R.
Quarkus is not just a backend framework. Rather, it’s a platform or ecosystem. With Quarkus you can write as JavaEE, as well as Spring applications, and even mix them, without thinking of underlying details.
So taking all that in mind, let’s see how you can freely re-use some of your Python code in Java
In this guide, you gonna see how easy it is to install GraalVM on Ubuntu Linux and start using awesome features like cross-language communication, faster JVM and more.
