Use wildcards in WASB ListBlobs

Question

I'm using Azure .Net SDK to list all blobs from Windows Azure Storage Blob container.

let client = account.CreateCloudBlobClient()
let container = client.GetContainerReference("my-container")
let list = container.ListBlobs("data/2014-*-17/", false) // ! here

as you can see i'm trying to filter blobs by wildcarded prefix.

Unfortunately this won't work as Azure Storage does not allow you to do server-side wild card filtering. Only filtering option available to you server-side is prefix filtering.

So what you would do is list blobs names of which starts with data/2014- and then apply rest of the filtering logic on the client side once you received all blobs names of which start with data/2014-.

let list = container.ListBlobs("data/2014-", false) // ! here
//Do client side filtering on the "list"
