- 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

map.

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.

Use this method to create a PromiseUnlessShutdown that will automatically be cancelled when the close context is closed. This allows proper clean up of stray promises when the node is transitioning to a passive state.

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.
