Memcached

case class Memcached(label: String, keyHasher: KeyHasher = ..., params: Params = Memcached.defaultParams) extends Product with Serializable

Stack based Ketama Memcache builder. It builds a Ketama Memcache client that dispatches through pipelining on a singleton pool, and uses KetamaFailureAccrualFactory that fails immediately when a node is marked dead.

For example, a client can be built through:

val client = Memcached(label).newClient(dest)

Note: newClient takes Name as param, and ONLY Bounded names are supported.

If you want to provide finely tuned configurations:

val client =
Memcached(label)
  .configured(FailureAccrualFactory.Param(30, () => 1.seconds))
  // tcp connection timeout
  .configured(Transporter.ConnectTimeout(100.milliseconds))
  // one single request timeout
  .configured(TimeoutFilter.Param(requestTimeout))
  // the acquisition timeout of a connection
  .configured(TimeoutFactory.Param(serviceTimeout))
  .configured(EjectFailedHost(false))
  .newClient(dest)
