Binary Memcached client for Go with SASL support

This repository is no longer maintained. You can find an actively maintained version of mc in the MemCachier fork.

mc.go: A pure Go driver for Memcached (binary protocol, thread-safe)

Install

	$ go get github.com/bmizerany/mc

Use

	import "github.com/bmizerany/mc"

	func main() {
		// Error handling omitted for demo
		cn, err := mc.Dial("tcp", "localhost:11211")
		if err != nil {
			...
		}

		// Only PLAIN SASL auth supported right now
		// See: http://code.google.com/p/memcached/wiki/SASLHowto
		err = cn.Auth("foo", "bar")
		if err != nil {
			...
		}
		

		val, cas, err = cn.Get("foo")
		if err != nil {
			...
		}

		exp = 3600 // 2 hours
		err = cn.Set("foo", "bar", cas, exp)
		if err != nil {
			...
		}

		err = cn.Del("foo")
		if err != nil {
			...
		}
	}

Please Contribute

Not all of the commands are implemented. Only the ones I immedietly needed. Each command is trival to implement. If you'd like add one, please do so and send a pull request.

The current commands are:

Get, Set, Del, Incr, Decr

Performance

Right now the mutex is by far the largest bottleneck. There are thoughts on how to reduce it's impact. Any help is always appreciated.
