Chunk upload to Windows Azure Blob by using WCF REST

Question

I'm using Windows Azure Blob Storage and WCF REST Services together to upload large files with chunk.

I can upload one part files easily, but I have to find a method to merge this chunks in an Azure Blob. What is the best practise to do this?

This is my interface:

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate="Upload?name={name}&chunk={chunk}&chunks={chunks}")]
int Upload(string name, string chunk, string chunks, Stream fileContents);

Answer 1

BlockBlob solved my problem. I can upload huge files as 256kb chunks easily. Here is the example which helped me: http://code.msdn.microsoft.com/windowsazure/Silverlight-Azure-Blob-3b773e26

Answer 2

I can't speak of how to interact with WCF, but if you need to improve your upload performance, you should look at using the block access pattern and running multiple threads.
