ParticipantEventPublisher
Companion object ParticipantEventPublisher
class ParticipantEventPublisher extends NamedLogging with FlagCloseableAsync
Helper to publish participant events in a thread-safe way. For "regular" SingleDimensionEventLogs representing domains thread safety is taken care of by the com.digitalasset.canton.participant.event.RecordOrderPublisher.
ParticipantEventPublisher also encapsulates the participant clock generating unique participant recordTime.
