Описание
Коротко и по делу о том, что важно знать про concurrency.
Start writing concurrent code that improves performance, scales up to handle large volumes of data, and takes full advantage of modern multi-processor hardware. Concurrency doesn’t need to be confusing. Too many developers think concurrency is extremely challenging. This book uses the easy-to-grasp concurrency tools of the Go language to demonstrate principles and techniques, steadily teaching you the best practices of effective concurrency. Learn Concurrent Programming with Go is here to prove them wrong! Techniques learned in this book can be applied to other languages.
In Learn Concurrent Programming with Go you will learn how to:Implement effective concurrency for more responsive, higher performing, scalable software
Avoid common concurrency problems such as deadlocks and race conditions
Manage concurrency using goroutines, mutexes, readers-writer locks, and more
Identify concurrency patterns such as pipelining, worker pools, and message passing
Discover advantages, limits, and properties of parallel computing
Improve your Go coding skills with advanced multithreading topics
In Learn Concurrent Programming with Go, you’ll discover universal principles of concurrency, along with how to use them for a performance boost in your Go applications. Concurrent programming allows multiple tasks to execute and interact simultaneously, speeding up performance and reducing user wait time. Expert author James Cutajar starts with the basics of modeling concurrency in your programs, demonstrates differences between message passing and memory sharing, and even introduces advanced topics such as atomic variables and futexes.
This book will show you how! About the technologyYou can improve almost any application’s performance and responsiveness by introducing concurrency into the codebase. It starts with the basics of concurrent programming and builds your skills step by step by exploring scenarios you’ll face every day as a developer. Author James Cutajar explains each aspect of concurrency in plain language using the intuitive features baked into the Go language.
In it, you’ll learn how to divide larger programming tasks into independent parts that can run simultaneously. About the bookLearn Concurrent Programming with Go provides a practical, hands-on introduction to creating software for modern multiprocessor systems. You’ll use the Go language to implement common concurrency patterns by utilizing readers-writer locks, semaphores, message passing, and memory sharing. The skills you learn will easily transfer to other languages.
