Hands-On High Performance with Go

By: Bob Strecansky

Overview of this book

Go is an easy-to-write language that is popular among developers thanks to its features such as concurrency, portability, and ability to reduce complexity. This Golang book will teach you how to construct idiomatic Go code that is reusable and highly performant. Starting with an introduction to performance concepts, you’ll understand the ideology behind Go’s performance. You’ll then learn how to effectively implement Go data structures and algorithms along with exploring data manipulation and organization to write programs for scalable software. This book covers channels and goroutines for parallelism and concurrency to write high-performance code for distributed systems. As you advance, you’ll learn how to manage memory effectively. You’ll explore the compute unified device architecture (CUDA) application programming interface (API), use containers to build Go code, and work with the Go build cache for quicker compilation. You’ll also get to grips with profiling and tracing Go code for detecting bottlenecks in your system. Finally, you’ll evaluate clusters and job queues for performance optimization and monitor the application for performance regression. By the end of this Go programming book, you’ll be able to improve existing code and fulfill customer requirements by writing efficient programs.

Composing Readable Go Code

Learning how to write readable Go code is an essential part of the language. Language developers used their previous experience while writing other languages to create a language that they felt was clear and concise. A commonly used phrase in describing the proper way to write with this language is idiomatic Go. This phrase is used to describe the correct way to program in Go. Style is often subjective, but the Go team has worked hard in order to write the language in an opinionated way and facilitate developer velocity, readability, and collaboration. In this chapter, we are going to talk about how to maintain some core tenets of the language:

  • Simplicity
  • Readability
  • Packaging
  • Naming
  • Formatting
  • Interfaces
  • Methods
  • Inheritance
  • Reflection

Understanding these patterns and idioms will help you to write Go code that is more easily readable and operable between...
