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
