In this talk, I gave an introduction to the underlying concepts of the Event Sourcing, CQRS and Memory Image patterns and one might go about implementing them with the tools available in the Scala ecosystem, specifically Akka. In the second part, I presented the Eventsourced library, demonstrating how it makes it pretty easy to develop an event-sourced application with Akka.

This talk was based on the workshop at flatMap(Oslo) 2013, see the links of that one for slides and the example project.
