mc.go: A Go client for Memcached
This is a (pure) Go client for Memcached. It supports the binary Memcached protocol and SASL authentication. It's thread-safe. It allows connections to entire Memcached clusters and supports connection pools, timeouts, and failover.
Install
Module-aware mode:
$ go get github.com/memcachier/mc/v3
Legacy GOPATH mode:
$ go get github.com/memcachier/mc
Use
import "github.com/memcachier/mc/v3"
// Legacy GOPATH mode:
// import "github.com/memcachier/mc"
func main() {
// Error handling omitted for demo
// Only PLAIN SASL auth supported right now
c := mc.NewMC("localhost:11211", "username", "password")
defer c.Quit()
exp := 3600 // 2 hours
cas, err = c.Set("foo", "bar", flags, exp, cas)
if err != nil {
...
}
val, flags, cas, err = c.Get("foo")
if err != nil {
...
}
err = c.Del("foo")
if err != nil {
...
}
}
Missing Feature
There is nearly coverage of the Memcached protocol.
The biggest missing protocol feature is support for multi_get
and other
batched operations.
There is also no support for asynchronous IO.
Performance
Right now we use a single per-connection mutex and don't support pipe-lining any operations. There is however support for connection pools which should make up for it.
Get involved!
We are happy to receive bug reports, fixes, documentation enhancements, and other improvements.
Please report bugs via the github issue tracker.
