Golang execute several go routine in loop and then wait
$begingroup$
I'm new in Go and excited with its easy-to-use concurrency implementation. However I'm not sure if I'm doing it right in Golang way.
Consider the code where I spawn process(i int, ch chan int) every loop as separate goroutine. Then the result which comes from the channel will be consumed by consume(ch chan int, wg *sync.WaitGroup).
I know that the channel is blocking, so let's implement buffered channel. And of course I don't want the process terminated before every goroutine finished the operation, so I add WaitGroup.
func main() {
var wg sync.WaitGroup
n := 5
ch := make(chan int, n)
for i := 0; i < n; i++ {
println("Processing ", i)
go process(i, ch)
go consume(ch, &wg)
}
println("Finished the process")
wg.Wait()
}
func consume(ch chan int, wg *sync.WaitGroup) {
wg.Add(1)
defer wg.Done()
println("Result ", <-ch)
}
func process(i int, ch chan int) {
ch <- (i * 5)
}
Am I doing it right? Or there are better way to do this?
Many thanks!
