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.

Comprehending inheritance in Go

Go does not have inheritance. Composition is used in order to embed items (mostly structs) in one another. This is convenient when you have a baseline struct that is used for many different functions, with other structs that build on top of the initial struct.

We can describe some of the items in my kitchen to show how inheritance works.

We can initialize our program as shown in the following code block. In this block, we create two structs:

Utensils: For the utensils I have in my drawers in my kitchen

Appliances: For the appliances I have in my kitchen

package main
import "fmt"

func main() {
type Utensils struct {
fork string
spoon string
knife string

type Appliances struct {
stove string
dishwasher string
oven string

I can next use Go's nested structuring to create a Kitchen...
