Read file geodatabase from a stream

Question

I can't seem to find a way to open a file geodatabase from a .Net Stream - is it possible in the current version? If not; is it on the roadmap?

I need this, and probably others to, to open a file geodatabase from things like Azure Blob.

My current solution, which I haven't tried yet, is to write the file to my WebApp local storage and open it from there. This is a hassle and I can't see why the SDK shouldn't be able to just take a Stream.

If you have access to an ArcGIS for Server, write an SOE to process the file and send the information back to your web app

Just to elaborate a bit more, we have a use case where file geodatabases (smallish) are being uploaded via our web application (azure website).  After the file is uploaded we would like to process information from the file (again inside the web application).  Initially we were thinking to save the file to a cloud storage service (azure blob) and then open it via a stream.

I believe this is a similar situation to the original post.

The runtime geodatabase format is based on SQLite, and will not support streams. You will be better off downloading it and opening it - believe me that'll be faster than doing a bunch of small reads to stream up to the cloud
