This article mainly introduces the Go concurrency method of what related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe you will have some gains after reading this Go concurrency method, let's take a look at it.

1. Goroutine1 and Coroutine

Golang supports concurrent programming at the language level, using a goroutine mechanism

The cooperative program is essentially a user-mode thread, which does not need the operating system to carry out preemptive scheduling, but it is parasitic in the thread, so the system overhead is very low, which can effectively improve the task concurrency of the thread and avoid the disadvantage of multi-thread. However, the cooperative program needs language support and requires users to implement the scheduler themselves. Because in the go language, the scheduler is implemented, so we can easily use the go keyword to use the cooperative program.

Func main () {for I: = 0; I
