public virtual void StartProcessing (System.Threading.CancellationToken cancellationToken = default);abstract member StartProcessing : System.Threading.CancellationToken -> unit
override this.StartProcessing : System.Threading.CancellationToken -> unitPublic Overridable Sub StartProcessing (Optional cancellationToken As CancellationToken = Nothing)Parameters
- 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.
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 StartProcessing(CancellationToken) to fail.
