In this example we'll look at how to implement a worker pool using goroutines and channels

package main

import (
    "fmt"
    "time"
)

func worker(id int, jobs <-chan int, result chan<- int) {
    for j := range jobs {
        fmt.Println("worker", id, "processing job", j)
        time.Sleep(time.Second)
        result <- j * 2
    }
}

func main() {
    jobs := make(chan int, 100)
    result := make(chan int, 100)

    for w := 1; w <= 3; w++ {
        go worker(w, jobs, result)
    }

    for j := 1; j <= 9; j++ {
        jobs <- j
    }

    close(jobs)

    for a := 1; a <= 9; a++ {
        fmt.Println("<-result", <-result)
    }
}
worker 1 processing job 1
worker 2 processing job 2
worker 3 processing job 3
worker 1 processing job 4
worker 2 processing job 5
worker 3 processing job 6
<-result 2
<-result 4
<-result 6
worker 1 processing job 7
worker 2 processing job 8
worker 3 processing job 9
<-result 8
<-result 10
<-result 12
<-result 14
<-result 16
<-result 18
