Ronald Dehuysser - A Java 8 lambda and JobRunr is all you need for distributed batch processing!

Rob Dehuysser, creator of JobRunr, introduces JobRunr: the ultimate open-source library for background processing in Java, recommended by ThoughtWorks. By transforming Java lambdas into distributed background tasks, JobRunr allows you to run any job at any time and on any JVM. He'll delve into its diverse features such as job persistence, automatic retries, scalability (hello k8s), and the integrated dashboard to provide you with a good grasp of the possibilities. Oh, and did you know it also works on GraalVM? The attendees will learn how bytecode in Java works. After this session, you’ll have a good idea of what JobRunr is, how it does its magic and how it will allow you to focus on delivering value to your end users instead of implementing scheduling over and over again.
