Learning Concurrent Programming in Scala - Second Edition

Overview of this book

Scala is a modern, multiparadigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. Scala smoothly integrates the features of object-oriented and functional languages. In this second edition, you will find updated coverage of the Scala 2.12 platform. The Scala 2.12 series targets Java 8 and requires it for execution. The book starts by introducing you to the foundations of concurrent programming on the JVM, outlining the basics of the Java Memory Model, and then shows some of the classic building blocks of concurrency, such as the atomic variables, thread pools, and concurrent data structures, along with the caveats of traditional concurrency. The book then walks you through different high-level concurrency abstractions, each tailored toward a specific class of programming tasks, while touching on the latest advancements of async programming capabilities of Scala. It also covers some useful patterns and idioms to use with the techniques described. Finally, the book presents an overview of when to use which concurrency library and demonstrates how they all work together, and then presents new exciting approaches to building concurrent and distributed systems. Who this book is written for If you are a Scala programmer with no prior knowledge of concurrent programming, or seeking to broaden your existing knowledge about concurrency, this book is for you. Basic knowledge of the Scala programming language will be helpful.

Getting started with Reactors

This section contains instructions on how to get Reactors working in your project. The Reactors framework has multiple languages frontend, and works on multiple platforms. At the time of writing this book, Reactors can be used with Scala and Java as a JVM library, or alternatively on NodeJS or inside the browser if you are using the Scala.js frontend of Reactors.

If you are developing with SBT, the easiest way is to include Reactors into your project as a library dependency. To get started with Reactors.IO, you should grab the latest snapshot version distributed on Maven. If you are using SBT, add the following to your project definition:

resolvers ++= Seq( 
  "Sonatype OSS Snapshots" at "", 
  "Sonatype OSS Releases" at "" 
libraryDependencies ++= Seq( 
  "io.reactors" %% "reactors" % "0.8") 

At the time of writing this, the latest version is 0.8 for...
