Blocks until all earlier tasks have completed and then prevents further tasks from being run.

Looks up an event by the given criterion.

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

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.

Check whether we're closing. Susceptible to race conditions; unless you're using using this as a flag to the retry lib or you really know what you're doing, prefer performUnlessClosing and friends.

track running futures on shutdown

set to true to get detailed information about all futures that did not complete during shutdown. if set to false, we don't do anything.

Performs the task given by f unless a shutdown has been initiated. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

DO NOT CALL this.close as part of f, because it will result in a deadlock.

Performs the EitherT[Future] given by etf unless a shutdown has been initiated, in which case the provided error is returned instead. Both etf and the error are lazy; etf is only evaluated if there is no shutdown, the error only if we're shutting down. The shutdown will only begin after etf completes, but other tasks may execute concurrently with etf, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingF). The tasks are assumed to take less than closingTimeout to complete.

DO NOT CALL this.close as part of etf, because it will result in a deadlock.

Performs the Future given by f unless a shutdown has been initiated. The future is lazy and not evaluated during shutdown. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

DO NOT CALL this.close as part of f, because it will result in a deadlock.

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.

The table name to store the pruning timestamp in. The table must define the following fields:

• partitionColumn primary key
• phase stores the com.digitalasset.canton.pruning.PruningPhase
• ts stores the com.digitalasset.canton.data.CantonTimestamp -

Register a task to run when shutdown is initiated.

You can use this for example to register tasks that cancel long-running computations, whose termination you can then wait for in "closeAsync".

Stores the given com.digitalasset.canton.sequencing.protocol.SequencedEvents. If an event with the same timestamp already exist, the event may remain unchanged or overwritten.

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