Returns the total number of contracts whose states are stored at the given timestamp.
Returns the total number of contracts whose states are stored at the given timestamp.
To get a consistent snapshot, the caller must ensure that the timestamp specifies a time that is not in the future, i.e., not after the timestamp of the clean cursor in the com.digitalasset.canton.participant.protocol.RequestJournal Note that the result may change between two invocations if prune is called in the meantime.

- def contractSnapshot(contractIds: Set[LfContractId], timestamp: CantonTimestamp)(implicit traceContext: TraceContext): EitherT[Future, AcsError, Map[LfContractId, CantonTimestamp]]
Returns a map to the timestamp when the contract became active for the last time before or at the given timestamp.
Returns a map to the timestamp when the contract became active for the last time before or at the given timestamp. Omits contracts that not active right after the given timestamp.
- timestamp
The timestamp at which the activeness of the contracts shall be determined. Must be before the timestamp that corresponds to the head cursor in the com.digitalasset.canton.participant.protocol.RequestJournal for the state com.digitalasset.canton.participant.protocol.RequestJournal.RequestState.Clean. If this precondition is violated, the returned snapshot may be inconsistent, i.e., it may omit some contracts that were ActiveContractStore.Active at the given time and it may include contracts that were actually ActiveContractStore.Archived or ActiveContractStore.TransferredAway.

- ActiveContractStore.SimultaneousActivation if the contract is transferred in at the same time or has been created by a different request at the same time.

- def deleteSince(criterion: RequestCounter)(implicit traceContext: TraceContext): Future[Unit]
Deletes all activeness changes from requests whose request counter is at least the given one.
Deletes all activeness changes from requests whose request counter is at least the given one. This method must not be called concurrently with creating, archiving, or transferring contracts.
Therefore, this method need not be linearizable w.r.t. creating, archiving, or transferring contracts. For example, if a request
rc1creates a contractcand another requestrc2archives it while deleteSince is running for somerc <= rc1, rc2, then there are no guarantees which of the effects ofrc1andrc2remain. For example,ccould end up being inexistent, active, or archived but never created, even if the writes forrc1andrc2are successful.- Definition Classes

Returns the latest com.digitalasset.canton.participant.store.ActiveContractStore.Status for the given contract IDs along with its com.digitalasset.canton.participant.util.TimeOfChange.
This method is used by the protocol processors for conflict detection. In-flight transactions may have changesets not yet written to the ACS datastore. Since only the com.digitalasset.canton.participant.protocol.conflictdetection.ConflictDetector tracks in-flight changesets, this method cannot be used as a source of valid data to other components.
If a contract is created or transferred-in and archived or transferred-out at the same com.digitalasset.canton.participant.util.TimeOfChange, the contract is ActiveContractStore.Archived or ActiveContractStore.TransferredAway. A contract cannot be archived and transferred out at the same timestamp.
- returns
The map from contracts in
contractIdsin the store to their latest state. Nonexistent contracts are excluded from the map.

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.

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.

Returns all contracts that were active right after the given timestamp, and when the contract became active for the last time before or at the given timestamp.
- timestamp
The timestamp at which the snapshot shall be taken. Must be before the timestamp that corresponds to the head cursor in the com.digitalasset.canton.participant.protocol.RequestJournal for the state com.digitalasset.canton.participant.protocol.RequestJournal.RequestState.Clean. If this precondition is violated, the returned snapshot may be inconsistent, i.e., it may omit some contracts that were ActiveContractStore.Active at the given time and it may include contracts that were actually ActiveContractStore.Archived or ActiveContractStore.TransferredAway.
- returns
A map from contracts to the latest timestamp (no later than the given
timestamp) when they became active again. It contains exactly those contracts that were active right after the given timestamp. If a contract is created or transferred-in and archived or transferred-out at the same timestamp, it does not show up in any snapshot. The map is sorted by cats.kernel.Order[com.digitalasset.canton.protocol.LfContractId].
