Answer 1

I invite you to take a look at titan-files . It's a powerful file-system abstraction on top of the DataStore and/or blob store. I'm using it for a commercial application and so far I've been very happy with it.

Answer 2

There is no built-in means to access the datastore through URLs. If you choose to, your application can implement URLs that return data from the datastore.
