What decides columns in Azure queues?

Question

I'm using Azure Queue storage. I just upgraded from using Microsoft.WindowsAzure.StorageClient to Microsoft.WindowsAzure.Storage. I've also recently changed over from using Lokad to CloudFx. At some point in the process, I started getting some more columns in Queue storage, including a duplicate Dequeue Count.

I can't figure out how those columns are getting created. Why are there two Dequeue Count columns?

Answer 1

The columns have nothing to do with the internal schema of the message. They display management metadata which is specific to the queue. "Dequeue Count" indicates how many times clients have attempted to dequeue the message.

The duplicate column issue looks to me like a UI bug in the management tool.
