Effective Concurrency in Go

By: Burak Serdar

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.

Handling Requests Concurrently

Server programming is a rather large topic. This chapter will mainly focus on some of the concurrency-related aspects of server programming and, in an abstract sense, request handling in general. At the end of the day, almost all programs are written to handle particular requests. For a server application, defining and propagating a request context is very important, so we start the chapter by talking about the context package. Next, we will look at some simple servers to explore how requests can be handled concurrently, and discuss some methods to deal with a few basic problems of server development. The last part of the chapter is on streaming data, where data elements are generated piecemeal, which poses unique challenges to demonstrate some interesting concurrency patterns.

This chapter includes the following sections:

  • The context, cancelations, and timeouts
  • Backend services
  • Streaming data
