How to use pipelines to implement pipeline architecture in Go language?

In the Go language, you can use pipelines to implement pipeline architecture. The steps are as follows: Create a pipeline. Create a goroutine for each pipe. In each goroutine, data is received from the pipe, processed, and then the result is sent to the next pipe (if needed).

How to use pipelines to implement pipeline architecture in Go language?

Pipeline architecture is a design pattern that divides a complex process into smaller, sequentially executed steps. Each step is an independent stage connected by pipelines that allow data to flow between stages.

In the Go language, you can use channels to implement pipeline architecture. A pipe is a data structure that allows concurrent sending of data from one goroutine to another.

To implement a pipeline line architecture using pipes, follow these steps:

1. Create a pipeline.
2. Create a goroutine for each pipeline.
3. In each goroutine, receive data from the pipe, process the data, and then send the result to the next pipe (if needed).

The following is a practical case that demonstrates how to use pipes to implement the pipeline line architecture in the Go language:

package main

import (
    "fmt"
    "time"
)

// 创建一个管道
var numbers = make(chan int)

// 创建一个生成数字的 goroutine
go func() {
    for i := 0; i < 10; i++ {
        // 向管道发送数字
        numbers <- i
        time.Sleep(time.Second)
    }
    // 关闭管道，表示不再发送数据
    close(numbers)
}

// 创建一个计算平方数的 goroutine
go func() {
    for n := range numbers {
        // 从管道接收数字
        fmt.Println("Received number:", n)
        // 计算平方数
        fmt.Println("Calculated square:", n*n)
    }
}

func main() {
    time.Sleep(11 * time.Second)
}

In this example, the first goroutine sends a number to the pipe, And the second goroutine receives the number from the pipe and calculates its square. Pipes serve as a data exchange medium between two goroutines, allowing them to run concurrently.
