- def addKeyStateUpdates(updates: Map[LfGlobalKey, (Status, TimeOfChange)])(implicit traceContext: TraceContext): EitherT[Future, ContractKeyJournalError, Unit]
Writes the given updates as a journal entry to the store with the given time of change.
Writes the given updates as a journal entry to the store with the given time of change. The updates need not be written atomically and can be written partially in case of an error.
- returns
Returns com.digitalasset.canton.participant.store.ContractKeyJournal.ContractKeyJournalError if a different count with the same com.digitalasset.canton.participant.util.TimeOfChange has been written for one of the keys in the
updatesmap.

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.

Returns the latest state for the given keys. The map contains only keys that are found in the store.
- returns
The map from identifiers in

- 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.

- 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.
