EventProcessorClient.PartitionInitializingAsync Event

Definition

Namespace:

Azure.Messaging.EventHubs

Assembly:

Azure.Messaging.EventHubs.Processor.dll

Package:

Azure.Messaging.EventHubs.Processor v5.11.2

Source:

EventProcessorClient.cs

Performs the tasks to initialize a partition, and its associated context, for event processing.

It is not recommended that the state of the processor be managed directly from within this method; requesting to start or stop the processor may result in a deadlock scenario, especially if using the synchronous form of the call.

public event Func<Azure.Messaging.EventHubs.Processor.PartitionInitializingEventArgs,System.Threading.Tasks.Task> PartitionInitializingAsync;

member this.PartitionInitializingAsync : Func<Azure.Messaging.EventHubs.Processor.PartitionInitializingEventArgs, System.Threading.Tasks.Task> 

Public Custom Event PartitionInitializingAsync As Func(Of PartitionInitializingEventArgs, Task) 

Event Type

Func<PartitionInitializingEventArgs,Task>

Exceptions

ArgumentException

If an attempt is made to remove a handler that doesn't match the current handler registered.

NotSupportedException

If an attempt is made to add a handler when one is currently registered.

Remarks

This handler will be invoked concurrently, limited to one call per partition. The processor will await each invocation before starting to process the associated partition.

The processor will wait indefinitely for execution of the handler to complete. It is recommended for implementations to avoid long-running operations, as they will delay processing for the associated partition.
