In this hands-on session we'll explore some techniques you can use when implementing a CQRS application using Akka and Scala.
First we'll show you how we can use the Scala Type System to build a domain model based on case classes and functional paradigms. Contrary to what common sense dictates, we'll demonstrate that functional programming is a very good fit for domain modeling.
We'll cover the following points:
The advantages and pitfalls of using Akka as a messaging subsystem
How to reliably propagate events from the command side to the query side of your CQRS application
How to recover from failure
How to fit it in an asynchronous programming model
During this hands-on session we'll build a simple CQRS application based on Play and Akka.
