CQRS with Event Sourcing, Scala, Akka and Cassandra

In this Scala with CQRS demo, we are going to build a scalable hotel bookings system using Akka and Cassandra. This is a long-form tutorial where we build everything from scratch, step by step. We manage hotel bookings, changes, cancellations and more, with a scalable distributed system built in Scala.
