013: Go's concurrency to the rescue
Real-world story about how Go's concurrency save a .NET performance issue I was having where I needed to call a process that takes 5 to 15 seconds to complete 6m times.
Go's worker queue pattern:
type WorderPool struct {
queue chan int
}
func (wp *WorkerPool) start() {
for i := 0; i < 500; i++ {
go funcIO {
for id := range wp.queue {
doSomething(id)
}
}()
}
}
func (wp *WorkerPool) add(id int) {
wp.queue <- id
}
type WorderPool struct {
queue chan int
}
func (wp *WorkerPool) start() {
for i := 0; i < 500; i++ {
go funcIO {
for id := range wp.queue {
doSomething(id)
}
}()
}
}
func (wp *WorkerPool) add(id int) {
wp.queue <- id
}
Best way to show support for the pod is by sharing it around and buying my course.
