Memcache Client in Go (golang)

Installing

$ go get gopkgs.com/memcache.v1

After this command memcache is ready to use. Its source will be in:

$GOPATH/src/gopkgs.com/memcache.v1

You can use go get -u -a for update all installed packages.

See available versions and documentation at http://gopkgs.com/memcache.

Example

import (
        "gopkgs.com/memcache.v1"
)

func main() {
     mc := memcache.New("10.0.0.1:11211", "10.0.0.2:11211", "10.0.0.3:11212")
     mc.Set(&memcache.Item{Key: "foo", Value: []byte("my value")})

     it, err := mc.Get("foo")
     ...
}

About

This is a memcache client library for the Go programming language (http://golang.org/). This is a high performance fork of the original library at http://github.com/bradfitz/gomemcache. The following is a comparison between the original library and this one:
