Three new books, Go Optimizations 101, Go Details & Tips 101 and Go Generics 101 are published now. It is most cost-effective to buy all of them through this book bundle in the Leanpub book store.

Concurrency Synchronization Overview

This article will explain what are synchronizations and list the synchronization techniques supported by Go.

What Are Concurrency Synchronizations?

Concurrency synchronizations means how to control concurrent computations (a.k.a., goroutines in Go)

What Synchronization Techniques Does Go Support?

The article channels in Go has shown that we can use channels to do synchronizations. Besides using channels, Go also supports several other common synchronization techniques, such as mutex and atomic operations. Please read the following articles to get how to do synchronizations with all kinds of techniques in Go:

We can also do synchronizations by making use of network and file IO. But such techniques are very inefficient within a single program process. Generally, they are used for inter-process and distributed synchronizations. Go 101 will not cover such techniques.

To understand these synchronization techniques better, it is recommended to know the memory order guarantees in Go.

The data synchronization techniques in Go will not prevent programmers from writing improper concurrent code. However these techniques can help programmers write correct concurrent code easily. And the unique channel related features make concurrent programming flexible and enjoyable.
