Lightbend Akka Cluster - Sharding (Java)

This course will show you how to use Akka Cluster Sharding in Java as part of a Reactive System.

About This Course

Akka Cluster Sharding allows us to build systems that can be responsive to our users needs. These systems are both elastic and resilient in part due to the message driven nature of the actors they are built on. In short, they are Reactive.

Your goal in this course will be to learn about Akka Cluster Sharding and its various features, while converting a stateless microservice into a stateful one. This will allow us to see the difference between a system that relies entirely on the database to provide consistent state, and a system that isn't beholden to the database to provide consistency.
