Questions tagged [azure-storage-queues]

Windows Azure supports two types of queue mechanisms: Windows Azure Queues and Service Bus Queues. Both of which are used to provide reliable, persistent messaging between applications.

Windows Azure Queues, which are part of the Windows Azure storage infrastructure, feature a simple REST-based Get/Put/Peek interface, providing reliable, persistent messaging within and between services.

Service Bus Queues are part of a broader Windows Azure messaging infrastructure that supports queuing as well as publish/subscribe, Web service remoting, and integration patterns.

While both queuing technologies exist concurrently, Windows Azure Queues were introduced first, as a dedicated queue storage mechanism built on top of the Windows Azure storage services. Service Bus Queues, introduced with the latest release of the Service Bus, are built on top of the broader "brokered messaging" infrastructure designed to integrate applications or application components that may span multiple communication protocols, data contracts, trust domains, and/or network environments.

Common uses of Queue storage include:

  • Creating a backlog of work to process asynchronously
  • Passing messages from a Windows Azure Web role to a Windows Azure Worker role

Why is the ApproximateMessageCount property on an Azure Storage queue nullable?

The title pretty much explains my question: If there are no messages in the Storage Queue, why would it not just return 0, assuming we were able to get the queue reference and make a connection? Instead, it returns null. Does it have to do with the…
