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.

Nowadays, we live in a world where more and more things are getting connected to the Internet. These things generate helpful information that is usually delivered in real time. Streaming helps you ingest, process, analyze, and store data in a quick and responsive manner. Unlike batching, streaming happens in a real-time (or near real-time) fashion, which brings a new set of challenges--race conditions, network failures, buffers, and so on.

Akka Streams is a module built on top of Akka to make the ingestion and processing of streams easier, using the actor model under the hood. It provides easy-to-use APIs to create streams that leverage the power of the Akka toolkit without explicitly defining actor behaviors and messages. This allows you to focus on logic and forget about all of the boilerplate code required to manage the actor. Akka Streams follows the Reactive Streams manifesto, which defines a standard for asynchronous stream processing.
