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.

Go distributed tracing

Implementing and investigating individual traces for Go programs can be a fruitful endeavor, giving a lot of output with respect to the data that results in requests to our programs. As enterprises have more and more distributed code bases with many more intricate calls that all interoperate with one another, tracing individual calls becomes untenable in the long run. There have been two projects that have tried to help with distributed tracing for Go, and these are the OpenCensus Go library and the OpenTelemetry library:

The maintainers of these projects have decided to converge these two projects and begin working on one code base, named OpenTelemetry. This new code base will allow for a simplified integration of distributed...
