NASYNC

a customizable async task pool for golang, (event bus, runtime)

Fetures

• less memory
• more effective
• max gorutines and memory customizable
• more safe

Simple Usage

nasync.Do(function)

Async Http Client

http.DefaultTransport.(*http.Transport).MaxIdleConns = 2000
http.DefaultTransport.(*http.Transport).MaxIdleConnsPerHost = 1000
	
nasync.Do(func() {
    resp, err := http.Get("http://example.com")
    if err == nil {
        io.Copy(ioutil.Discard, resp.Body)
        resp.Body.Close()
    }
})

Advanced Usage

go get github.com/ti/nasync

import "github.com/ti/nasync"

func main() {
        //new a async pool in max 1000 task in max 1000 gorutines
        async := nasync.New(1000,1000)
        defer async.Close()
        async.Do(doSometing,"hello word")
}


func doSometing(msg string) string{
	return "i am done by " + msg
}

WHY

golang is something easy but fallible language, you may do this

   func yourfucntion() {
            go dosomething()  // this will got error on high load
    }

you may get "too many open files" error, when your application in High load, so you need this, you can do any thing in async by this, it is trusty。your can use this for:

• http or file writer logging
• improve main thread speed
• limited background task pool

What if something callback ?

import "github.com/ti/nasync"

func main() {
        nasync.Do(func() {
        		result := doSometing("msg")
        		fmt.Println("i am call back by ",result)
        })
}

func doSometing(msg string) string{
	return "i am done by " + msg
}
