counter

This is a Go library to increment a counter for a window of time (say last 60 second). Its resolution is 1 second.

Results will be periodically saved in a local file.

Installation

$ go get github.com/kavehmz/counter

Usage

# to test it as a http server you can do:
$ go run -race example/main.go

package main

import (
    "fmt"
    "github.com/kavehmz/counter"
)

func main() {
    c := counter.Init("/tmp/counter", time.Second, 60)
    ch := make(chan int)
    c.Inc(ch)
    fmt.Println(<-ch)
}

Algorithm

This lib is using and travesing a linked list to keep track of counts.
