Phase37Synchronizer
Companion object Phase37Synchronizer
class Phase37Synchronizer extends NamedLogging
Synchronizes the request processing of phases 3 and 7. At the end of phase 3, every request must signal that it has reached com.digitalasset.canton.participant.protocol.RequestJournal.RequestState.Confirmed via markConfirmed or markTimeout. At the beginning of phase 7, requests can wait on the completion of phase 3 via awaitConfirmed.
Eventually, all requests above initRc should signal via markConfirmed or skipRequestCounter.
Otherwise, the synchronizer becomes a memory leak.
This class assumes that the timestamps in request IDs grow strictly with the non-skipped request counters.
