Returns a checkpoint for the Event Hub, consumer group, and partition ID associated with the event processor instance, so that processing for a given partition can be properly initialized.

protected override System.Threading.Tasks.Task<Azure.Messaging.EventHubs.Primitives.EventProcessorCheckpoint> GetCheckpointAsync (string partitionId, System.Threading.CancellationToken cancellationToken);

override this.GetCheckpointAsync : string * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Messaging.EventHubs.Primitives.EventProcessorCheckpoint>

Protected Overrides Function GetCheckpointAsync (partitionId As String, cancellationToken As CancellationToken) As Task(Of EventProcessorCheckpoint)

Parameters

partitionId: String

The ID of the partition for which to retrieve the checkpoint.

cancellationToken: CancellationToken

A CancellationToken instance to signal the request to cancel the processing. This is most likely to occur when the processor is shutting down.

Returns

Task<EventProcessorCheckpoint>

The checkpoint for the processor to take into account when initializing partition.

Remarks

Should a partition not have a corresponding checkpoint, the default starting position set by the PartitionInitializingAsync handler will be applied. If no partition-specific starting point was specified, the DefaultStartingPosition will be used to initialize the partition for processing.
