trait PersistentEntityRegistry extends AnyRef

At system startup all PersistentEntity classes must be registered here with PersistentEntityRegistry#register.

Later, PersistentEntityRef can be retrieved with PersistentEntityRegistry#refFor. Commands are sent to a PersistentEntity using a PersistentEntityRef.

Abstract Value Members

  1. abstract def eventStream[Event <: AggregateEvent[Event]](aggregateTag: AggregateEventTag[Event], fromOffset: Offset): Source[Pair[Event, Offset], NotUsed]

    Permalink

    A stream of the persistent events that have the given aggregateTag, e.g.

    A stream of the persistent events that have the given aggregateTag, e.g. all persistent events of all Order entities.

    The type of the offset is journal dependent, some journals use time-based UUID offsets, while others use sequence numbers. The passed in fromOffset must either be Offset#NONE, or an offset that has previously been produced by this journal.

    Exceptions thrown

    IllegalArgumentException If the fromOffset type is not supported by this journal.

  2. abstract def gracefulShutdown(timeout: FiniteDuration): CompletionStage[Done]

    Permalink

    Gracefully stop the persistent entities and leave the cluster.

    Gracefully stop the persistent entities and leave the cluster. The persistent entities will be started on another node when new messages are sent to them.

    returns

    the CompletionStage is completed when the node has been removed from the cluster

    Retrieve a PersistentEntityRef for a given PersistentEntity class and identifier.

    This method will only work with journals that support UUID offsets. Journals that produce sequence offsets will fail during stream handling.
