public virtual System.Threading.Tasks.Task StartProcessingAsync (System.Threading.CancellationToken cancellationToken = default);abstract member StartProcessingAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task
override this.StartProcessingAsync : System.Threading.CancellationToken -> System.Threading.Tasks.TaskPublic Overridable Function StartProcessingAsync (Optional cancellationToken As CancellationToken = Nothing) As TaskParameters
- cancellationToken
- CancellationToken
A CancellationToken instance to signal the request to cancel the start operation. This won't affect the EventProcessor<TPartition> once it starts running.
Returns
Exceptions
As the processor starts, it will attempt to detect configuration and permissions errors that would prevent it from being able to recover without intervention. For example, an incorrect connection string or the inability to query the Event Hub would be detected. These exceptions will be packaged as an AggregateException, and will cause StartProcessingAsync(CancellationToken) to fail.
