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.

Understanding the configuration of Akka HTTP

Akka HTTP comes with a handful of configuration parameters to fine-tune your application. As usual, with Akka-related projects, the configuration gets defined in the Typesafe configuration file application.conf. In this recipe, we will learn how to set and override the most common configuration parameters. Specifically, we will override a configuration parameter for the Akka HTTP server, another configuration parameter for the Akka HTTP client and finally we will see how to modify the default values when parsing HTTP Requests. This is valuable if you need to reject requests of specific characteristics.

Getting ready

To begin with, we need to differentiate between different sets of configuration parameters. Akka HTTP projects contain multiple modules:

  • Akka-http-core: This contains configuration parameters for a low-level implementation, for both client and server APIs
  • Akka-http: This contains configuration parameters for a high-level implementation...
