Class JournalEntry


  • @PublicApi
    @ParametersAreNonnullByDefault
    public class JournalEntry
    extends Object
    Entry in a journal. Journal entries contain a message that should be processed at some point of time in the future.

    Typical user of journal entries is indexing subsystem, where it's important that indexes on all cluster nodes will be kept in sync. When a document changes, indexing subsystem would create a new journal entry with details of the change. Later on nodes will ask for these entries and then update their indexes accordingly.
