Gomemcached

Gomemcached is a Golang Memcached client designed to interact with multiple instances as shards. Implements sharding using a Consistent Hash.

Configuration

    - name: MEMCACHED_HEADLESS_SERVICE_ADDRESS
      value: "my-memchached-service-headless.namespace.svc.cluster.local"

MEMCACHED_HEADLESS_SERVICE_ADDRESS groups all memcached instances by ip addresses using dns lookup.

Default Memcached port is 11211, but you can also specify it in config.

    - name: MEMCACHED_PORT
      value: "12345"

For local run or if you have a static amount and setup of pods you can specify Servers (list separated by commas along with the port) manually instead of setting the HeadlessServiceAddress:

  - name: MEMCACHED_SERVERS
    value: "127.0.0.1:11211,192.168.0.1:1234"

Usage

Initialization client and connected to memcached servers.

    mcl, err := memcached.InitFromEnv()
    mustInit(err)
    a.AddCloser(func () error {
        mcl.CloseAllConns()
        return nil
    })

More examples

To use SASL specify option for InitFromEnv:

    memcached.InitFromEnv(memcached.WithAuthentication("<login>", "<password>"))

Can use Options with InitFromEnv to customize the client to suit your needs. However, for basic use, it is recommended to use the default client implementation.
