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. - 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.In addition to subscribing to individual keys it is possible to subscribe to all keys with a given prefix by using a
*
at the end of the keyid
. For exampleGCounterKey("counter-*")
. Notifications will be sent for all matching keys, also new keys added later.Subscribers will be notified periodically with the configured
notify-subscribers-interval
, and it is also possible to send an explicitFlushChanges
message to theReplicator
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 Deleted message.
If the key is expired the subscriber is notified with an Expired message.

.Send this message to the local
Replicator
to update a data value for the givenkey
. TheReplicator
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 themodify
function. It isNone
if there is no value for thekey
, and otherwiseSome(data)
. The function is supposed to return the new value of the data, which will then be replicated according to the givenwriteConsistency
.The
modify
function is called by theReplicator
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 accesssender()
reference of an enclosing actor. - final case class UpdateDataDeleted[A <: ReplicatedData](key: Key[A], request: Option[Any]) extends UpdateResponse[A] with Product with Serializable
