    Performs the task given by f unless a shutdown has been initiated. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

  52. def publicationTimeLowerBound: CantonTimestamp

    Returns a lower bound on the latest publication time of a published event.

  53. def publish(data: PublicationData): Future[Unit]

    Appends a new event to the event log.

    Appends a new event to the event log.

    The new event must already have been published in the SingleDimensionEventLog with id MultiDomainEventLog.PublicationData.eventLogId at offset MultiDomainEventLog.PublicationData.localOffset.

    The method is idempotent, i.e., it does nothing, if it is called twice with the same com.digitalasset.canton.participant.store.EventLogId and com.digitalasset.canton.participant.LocalOffset.

    The returned future completes already when the event has been successfully inserted into the internal (in-memory) inbox. Events will be persisted asynchronously. Actual publication has happened before a subsequent flush call's future completes.

    The caller must await completion of the returned future before calling the method again. Otherwise, the method may fail with an exception or return a failed future. (This restriction arises, because some implementations will offer the event to an Akka source queue, and the number of concurrent offers for such queues is bounded.)

    The event log will stall, i.e., log an error and refuse to publish further events in the following cases:

    • If an event cannot be persisted, even after retrying.
    • If events are published out of order, i.e., publish(id, o2).flatMap(_ => publish(id, o1)) with o1 < o2. Exception: The event log will not stall in case of republication of previously published events, i.e., publish(id, o1).flatMap(_ => publish(id, o2).flatMap(_ => publish(id, o1))) will not stall the event log.
