Data. We’re producing more and more of it. We store it in large NoSQL databases and feed it to hungry AI models. But how do we efficiently manage those massive data streams? How do we move, merge and transform those streams and, most importantly, do it in such a way that Java and Kotlin Developers love it?

In this talk, I will introduce Reactor: a Java Framework that uses the power of Reactive Programming to build highly flexible and scalable data pipelines. We will have a look at the history and fundamental concepts behind Reactive Programming and find out why this programming style is so satisfying to use. We will also explore Reactor’s extensive integration with the Spring Framework, with plenty of live code examples.

After this talk, you will be able to build your own Reactive data pipelines in either Java or Kotlin and experience firsthand how much fun this is! And as a little extra, you might even find out how Reactor uses the new Java 21 Virtual Threads…
