Building a CQRS application using the Scala Type System and Akka

Please log in to watch this conference skillscast.

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.

Secondly we'll explore the available options when integrating it with Akka and Akka Persistence.

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.
