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

Finds unpublished events in the single dimension event log. More precisely, finds all events from id with:

• local offset strictly greater than the local offset of the last published event from id
• local offset smaller than or equal to upToInclusiveO (if defined).

Returns a future that completes after all publications have happened whose publish future has completed before the call to flush.

Yields the smallest global offset whose publication time is at or after fromInclusive, if any. The publication time is measured on the participant's local clock.

Yields the largest global offset whose publication time is before or at upToInclusive, if any. The publication time is measured on the participant's local clock.

Returns the com.digitalasset.canton.participant.GlobalOffset under which the given local offset of the given event log was published, if any, along with its publication time

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.

Yields the greatest local offsets for the underlying SingleDimensionEventLog with global offset less than or equal to upToInclusive.

Yields the highest global offset up to the given bound, if any.

Returns the last linearized com.digitalasset.canton.participant.LocalOffset for the SingleDimensionEventLog id, if any

Returns the greatest local offset of the SingleDimensionEventLog given by eventLogId, if any, such that the following holds:

• The assigned global offset is below or at upToInclusive.
• The record time of the event is below or at timestampInclusive

Yields the deltaFromBeginning-lowest global offset (if it exists). I.e., locateOffset(0) yields the smallest offset, localOffset(1) the second smallest offset, and so on.

Yields the global offset, event and publication time for all the published events with the given IDs. Unpublished events are ignored.

Yields all events with offset up to upToInclusive.

Returns the data associated with the given offset, if any

Find the domain of a committed transaction.

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.

Removes all events with offset up to upToInclusive.

Returns a lower bound on the latest publication time of a published event. All events published later will receive the same or higher publication time. Increases monotonically, even across restarts.

Appends a new event to the event log.

The new event must already have been published in the SingleDimensionEventLog with id MultiDomainEventLog.PublicationData.eventLogId at offset MultiDomainEventLog.PublicationData.localOffset.

The method is idempotent, i.e., it does nothing, if it is called twice with the same com.digitalasset.canton.participant.store.EventLogId and com.digitalasset.canton.participant.LocalOffset.

The returned future completes already when the event has been successfully inserted into the internal (in-memory) inbox. Events will be persisted asynchronously. Actual publication has happened before a subsequent flush call's future completes.

The caller must await completion of the returned future before calling the method again. Otherwise, the method may fail with an exception or return a failed future. (This restriction arises, because some implementations will offer the event to an Akka source queue, and the number of concurrent offers for such queues is bounded.)

The event log will stall, i.e., log an error and refuse to publish further events in the following cases:

• If an event cannot be persisted, even after retrying.
• If events are published out of order, i.e., publish(id, o2).flatMap(_ => publish(id, o1)) with o1 < o2. Exception: The event log will not stall in case of republication of previously published events, i.e., publish(id, o1).flatMap(_ => publish(id, o2).flatMap(_ => publish(id, o1))) will not stall the event log.

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".

Sets the listener to be called whenever events are published to the multi-domain event log.

Yields an akka source with all stored events, optionally starting from a given offset.
