trait SingleDimensionEventLog[+Id <: EventLogId] extends SingleDimensionEventLogLookup

An event log for a single domain or for a domain-independent events (such as package uploads). Supports out-of-order publication of events.

Abstract Value Members

  1. abstract def deleteSince(inclusive: LocalOffset)(implicit traceContext: TraceContext): Future[Unit]

    Deletes all events whose request counter is at least inclusive.

    Deletes all events whose request counter is at least inclusive. This operation need not execute atomically.

  5. abstract def existsBetween(timestampInclusive: CantonTimestamp, localOffsetInclusive: LocalOffset)(implicit traceContext: TraceContext): Future[Boolean]

    Returns whether there exists an event in the event log with an com.digitalasset.canton.participant.LocalOffset of at most localOffset whose timestamp is at least timestamp.

    Returns whether there exists an event in the event log with an com.digitalasset.canton.participant.LocalOffset of at most localOffset whose timestamp is at least timestamp.

    In an event logs where timestamps need not increase with offsets, this can be used to check that whether there are events with lower offsets and larger timestamps.

  6. abstract def id: Id
  7. abstract def insertsUnlessEventIdClash(events: Seq[TimestampedEventAndCausalChange])(implicit traceContext: TraceContext): Future[Seq[Either[TimestampedEvent, Unit]]]

    Publishes many events.

    Publishes many events.

    returns

    For each event in events in the same order: scala.Left$ of the conficting event if an event with the same event ID has been published with a different (unpruned) com.digitalasset.canton.participant.LocalOffset. scala.Right$ if the event has been successfully inserted or has already been present in the event log

    Exceptions thrown

    java.lang.IllegalArgumentException if a different event has already been published with the same com.digitalasset.canton.participant.LocalOffset as one of the events in events.

    Exceptions thrown

    java.lang.IllegalArgumentException if a different event has already been published with the same com.digitalasset.canton.participant.LocalOffset or an event with the same com.digitalasset.canton.participant.sync.TimestampedEvent.EventId has been published with a different (unpruned) com.digitalasset.canton.participant.LocalOffset.

  12. def insertUnlessEventIdClash(event: TimestampedEvent, causalityUpdate: Option[CausalityUpdate])(implicit traceContext: TraceContext): EitherT[Future, TimestampedEvent, Unit]

    Publishes an event and the change in causality state associated with the event.

    returns

    scala.Left$ if an event with the same event ID has been published with a different (unpruned) com.digitalasset.canton.participant.LocalOffset. Returns the conflicting event.
