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.

In this chapter, we studied what concurrent programming is and why Scala is a good language for concurrency. We gave a brief overview of what you will learn in this book, and how the book is organized. Finally, we stated some Scala preliminaries necessary for understanding the various concurrency topics in the subsequent chapters. If you would like to learn more about sequential Scala programming, we suggest that you read the book, Programming in Scala, Martin Odersky, Lex Spoon, and Bill Venners, Artima Inc.

In the next chapter, we will start with the fundamentals of concurrent programming on the JVM. We will introduce the basic concepts in concurrent programming, present the low-level concurrency utilities available on the JVM, and learn about the Java Memory Model.
