Hi @antoine​ 

 

The Azure Blob Storage Connector currently only supports the block type of Azure blobs.

There's a useful doc page from Azure explaining the differences here.

 

If you'd like to see support for append or page blobs, please file add this as an idea.

As the possible actions are Delete / Download / List / Upload I assume you use Upload?

Thanks, indeed it seems "that's what it is" for now.

Nevertheless, I think (more like hope as I did not go deep in the doc) that the API allows appending. So I have hope that @gerhardatsafe might add it to the package one day if we ask him nicely. I could also try to explore the package python but it would be far far slower..
