How to limit the size of an azure blob container?

Question

In my application, a web service send a shared access signature (write rights on container) to the client so it can upload files.

Is there any way to limit the size (1Gb for instance) of uploaded content ? The ideal solution would be a custom size limit on the container. Otherwise it could be a limit on the shared access signature.

I could also change my application to send a share access signature on individual blobs if the feature is available on blobs.

Answer 1

Windows Azure does not provide limit per container. The limit provided by Windows Azure is by storage account (100 TB/account) and by individual blob (200 GB max. for a block blob and 1 TB max. for a page blob). For your requirement, I think you would need to implement this limit in your application.

Answer 2

The concept of trusting the client over the date size to be sent is pretty dangerous, especially for a service that bills depending on the size of the data transferred and stored.

The client could be a public HTML website. Any user who could leak the SAS by calling your service, would be able to send an enormous file.

I think the SAS should specify the maximum size of data that can be read, of written, for a given container / BLOB.
