Receiving device to cloud messages - Do I need to attach a storage account to my IOT Hub to use EventProcessorClient

Question

I am currently following the example here to receive the cloud messages. In that example I am using ReadEventsAsync.
The example however states that:

// The "ReadEventsAsync" method on the consumer is a good starting point for consuming events for prototypes
// and samples. For real-world production scenarios, it is strongly recommended that you consider using the
// "EventProcessorClient" from the "Azure.Messaging.EventHubs.Processor" package.

Now after looking at the EventProcessorClient here it seems like the EventProcessorClient requires the following

var storageConnectionString = "<< CONNECTION STRING FOR THE STORAGE ACCOUNT >>";  
var blobContainerName = "<< NAME OF THE BLOB CONTAINER >>";  

My question is do I need to attach an Azure Storage to the IOT Hub in order to use EventProcessorClient

Hello anonymous user ,
For other's reference this is where you found the statement: https://github.com/Azure-Samples/azure-iot-samples-csharp/blob/master/iot-hub/Quickstarts/read-d2c-messages/ReadDeviceToCloudMessages.cs#L47

My question is do I need to attach an Azure Storage to the IOT Hub in order to use EventProcessorClient

The association of an Azure Storage account to your IoT Hub is only used when you want to Upload Files with IoTHub. You can nevertheless use the same Azure Storage Account both for your EventProcessorClient to persist checkpoints as blobs and for your IoT devices to upload the files to storage.
