Overview of this book

The Go language has been gaining momentum due to its treatment of concurrency as a core language feature, making concurrent programming more accessible than ever. However, concurrency is still an inherently difficult skill to master, since it requires the development of the right mindset to decompose problems into concurrent components correctly. This book will guide you in deepening your understanding of concurrency and show you how to make the most of its advantages. You’ll start by learning what guarantees are offered by the language when running concurrent programs. Through multiple examples, you will see how to use this information to develop concurrent algorithms that run without data races and complete successfully. You’ll also find out all you need to know about multiple common concurrency patterns, such as worker pools, asynchronous pipelines, fan-in/fan-out, scheduling periodic or future tasks, and error and panic handling in goroutines. The central theme of this book is to give you, the developer, an understanding of why concurrent programs behave the way they do, and how they can be used to build correct programs that work the same way in all platforms. By the time you finish the final chapter, you’ll be able to develop, analyze, and troubleshoot concurrent algorithms written in Go.

Go Concurrency Primitives

This chapter is about the fundamental concurrency facilities of the Go language. We will first talk about goroutines and channels, the two concurrency building blocks that are defined by the language. Then, we also look at some of the concurrency utilities that are included in the standard library. We will cover the following topics:

  • Goroutines
  • Channels and the select statement
  • Mutexes
  • Wait groups
  • Condition variables

By the end of this chapter, you will have enough under your belt to tackle basic concurrency problems using language features and standard library objects.
