public class SegmentedFileJournal
extends akka.persistence.journal.japi.AsyncWriteJournal

An Akka persistence journal implementation on top of SegmentedJournal. This actor represents aggregation of multiple journals and performs a receptionist job between Akka and invidual per-persistenceId actors. See SegmentedJournalActor for details on how the persistence works.
