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.

Timers and Tickers

Many long-lived applications impose limits on how long an operation can last. They also perform tasks such as health checks periodically to ensure all components are working as expected. Many platforms provide high-precision timer operations, and the Go standard library provides portable abstractions of these services in the time package. We will look at timers and tickers in this chapter. Timers are tools for doing things later, and tickers are tools for doing things periodically.

The key sections we will review in this chapter are the following:

  • Timer – running something later
  • Tickers – running something periodically

At the end of this chapter, you will have seen how to work with timers and tickers and how you can monitor other goroutines using heartbeats.
