   Send this message to the local Replicator to retrieve a data value for the given key. The Replicator will reply with one of the GetResponse messages.

   The optional request context is included in the reply messages. This is a convenient way to pass contextual information (e.g. original sender) without having to use ask or maintain local correlation data structures.

20.  final case class StoreFailure [A <: ReplicatedData](key: Key[A], request: Option[Any]) extends UpdateFailure[A] with DeleteResponse[A] with Product with Serializable

    The local store or direct replication of the Update could not be fulfill according to the given consistency level due to durable store errors.

    The local store or direct replication of the Update could not be fulfill according to the given consistency level due to durable store errors. This is only used for entries that have been configured to be durable.

    The Update was still performed in memory locally and possibly replicated to some nodes, but it might not have been written to durable storage. It will eventually be disseminated to other replicas, unless the local replica crashes before it has been able to communicate with other replicas.

21.  final case class Subscribe [A <: ReplicatedData](key: Key[A], subscriber: ActorRef) extends ReplicatorMessage with Product with Serializable

    Register a subscriber that will be notified with a Changed message when the value of the given key is changed.

    Register a subscriber that will be notified with a Changed message when the value of the given key is changed. Current value is also sent as a Changed message to a new subscriber.

    Subscribers will be notified periodically with the configured notify-subscribers-interval, and it is also possible to send an explicit FlushChanges message to the Replicator to notify the subscribers immediately.

    The subscriber will automatically be unregistered if it is terminated.

    If the key is deleted the subscriber is notified with a DataDeleted message.

23.  final case class Update [A <: ReplicatedData](key: Key[A], writeConsistency: WriteConsistency, request: Option[Any])(modify: (Option[A]) ⇒ A) extends Command[A] with NoSerializationVerificationNeeded with Product with Serializable

    Send this message to the local Replicator to update a data value for the given key.

    Send this message to the local Replicator to update a data value for the given key. The Replicator will reply with one of the UpdateResponse messages.

    Note that the companion object provides apply functions for convenient construction of this message.

    The current data value for the key is passed as parameter to the modify function. It is None if there is no value for the key, and otherwise Some(data). The function is supposed to return the new value of the data, which will then be replicated according to the given writeConsistency.

    The modify function is called by the Replicator actor and must therefore be a pure function that only uses the data parameter and stable fields from enclosing scope. It must for example not access sender() reference of an enclosing actor.
