Akka Cookbook

By: Vivek Mishra, Héctor Veiga Ortiz

Overview of this book

Akka is an open source toolkit that simplifies the construction of distributed and concurrent applications on the JVM. This book will teach you how to develop reactive applications in Scala using the Akka framework. This book will show you how to build concurrent, scalable, and reactive applications in Akka. You will see how to create high performance applications, extend applications, build microservices with Lagom, and more. We will explore Akka's actor model and show you how to incorporate concurrency into your applications. The book puts a special emphasis on performance improvement and how to make an application available for users. We also make a special mention of message routing and construction. By the end of this book, you will be able to create a high-performing Scala application using the Akka framework.

Preface

Integrating with Akka


Lagom is built on top of Play and Akka, so it is not surprising that the framework provides capabilities to interact with Akka actors. This makes Lagom really interesting for Akka developers who already have developed applications. It is easy and possible to migrate your Akka applications to microservices using Lagom. Another good use case for Akka in Lagom is when using clustered services. In this case, a developer might want to use a consistent hashing group of actors in order to ensure that the data always ends in the same actor even if it was received from different instances of a given service.

In this recipe, we will explore how to access the actor system to be able to leverage all the Akka power we have been learning through the book. 

Getting ready

To step through this recipe, we need to import the Lagom Akkacoobook project that we created in the initial recipe of this chapter; all other prerequisites are the same as earlier.
