EventProcessorClient.GetCheckpointAsync(String, CancellationToken) Method

Definition

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

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.
