asyncWriteMessages

scala.concurrent.Future<scala.runtime.BoxedUnit> asyncWriteMessages(scala.collection.immutable.Seq<PersistentRepr> messages)
Plugin API: asynchronously writes a batch of persistent messages to the journal. The batch write must be atomic i.e. either all persistent messages in the batch are written or none.


asyncWriteConfirmations

scala.concurrent.Future<scala.runtime.BoxedUnit> asyncWriteConfirmations(scala.collection.immutable.Seq<PersistentConfirmation> confirmations)
Plugin API: asynchronously writes a batch of delivery confirmations to the journal.


asyncDeleteMessages

scala.concurrent.Future<scala.runtime.BoxedUnit> asyncDeleteMessages(scala.collection.immutable.Seq<PersistentId> messageIds,
                                                                     boolean permanent)
Plugin API: asynchronously deletes messages identified by messageIds from the journal. If permanent is set to false, the persistent messages are marked as deleted, otherwise they are permanently deleted.


asyncDeleteMessagesTo

scala.concurrent.Future<scala.runtime.BoxedUnit> asyncDeleteMessagesTo(java.lang.String processorId,
                                                                       long toSequenceNr,
                                                                       boolean permanent)
Plugin API: asynchronously deletes all persistent messages up to toSequenceNr (inclusive). If permanent is set to false, the persistent messages are marked as deleted, otherwise they are permanently deleted.
