    Parameters to control prune batching

    Parameters to control prune batching

    If defined, then the pruning window will be computed such that it targets the ideal target batch size in order to optimize the load on the database.

    This is currently used with the journal stores. Normal pruning of other stores already does batching on its own.

    Looks up a set of sequenced events within the given range.

    limit

    The maximum number of elements in the returned iterable, if set.

    Marks events between from and to as ignored. Fills any gap between from and to by empty ignored events, i.e. ignored events without any underlying real event.

    returns

    ChangeWouldResultInGap if there would be a gap between the highest sequencer counter in the store and from.

  28. final def prune(limit: CantonTimestamp)(implicit errorLoggingContext: ErrorLoggingContext, closeContext: CloseContext): Future[Unit]

    Prune all unnecessary data relating to events before the given timestamp.

    Prune all unnecessary data relating to events before the given timestamp.

    The meaning of "unnecessary", and whether the limit is inclusive or exclusive both depend on the particular store. The store must implement the actual pruning logic in the doPrune method.

  29. def pruningStatus(implicit traceContext: TraceContext): Future[Option[PruningStatus]]

    Returns the latest timestamp at which pruning was started or completed.

    Returns the latest timestamp at which pruning was started or completed. For com.digitalasset.canton.pruning.PruningPhase.Started, it is guaranteed that no pruning has been run on the store after the returned timestamp. For com.digitalasset.canton.pruning.PruningPhase.Completed, it is guaranteed that the store is pruned at least up to the returned timestamp (inclusive). That is, another pruning with the returned timestamp (or earlier) has no effect on the store. Returns scala.None$ if no pruning has ever been started on the store.

    Removes the ignored status from all events between from and to.

    returns

    ChangeWouldResultInGap if deleting empty ignored events between from and to would result in a gap in sequencer counters.
