Programming Reactive Systems

Reactive programming is a set of techniques for implementing scalable, resilient and responsive systems as per the Reactive Manifesto. Such systems are based on asynchronous message-passing, and their basic building-blocks are event handlers.

This course teaches how to implement reactive systems in Scala and Akka by using high-level abstractions, such as actors, asynchronous computations, and reactive streams. You will learn how to: – use, transform and sequence asynchronous computations using Future values – write concurrent reactive systems based on Actors and message passing, using untyped Akka and Akka Typed – design systems resilient to failures – implement systems that can scale out according to a varying workload – transform and consume infinite and intermittent streams of data with Akka Stream in a non-blocking way – understand how back-pressure controls flows of data
