Part 3. Advanced topics

This part introduces advanced topics related to building reactive web applications. You’ll learn how to use Akka Streams, an implementation of the Reactive Streams standard, to perform asynchronous and fault-tolerant stream processing. We’ll then talk about what’s necessary to deploy a reactive web application built with Play. Finally, we’ll discuss how to test a reactive web application to see if it behaves under load as you’d want it to.
