import (
   "io"
   "log"
   "os"
)

type test struct {
   name string
}

func (a *test) Read(p []byte) (int, error) {

    var size int
   for {
       // I want to  put large data to response the read ; some data 
whatever I want ...

        size = size + 102400
       // condition  to break
       break
   }

    return size, nil
}

func main() {
   r := &test{name: "test"}
   if _, err := io.Copy(os.Stdout, r); err != nil {
       log.Fatal(err)
   }
