Code isn't aware of region groups

[sujal]

The documentation should either specify that the database needs to be created in Classic or the code needs to be refactored to be region group aware. It probably should be part of the setup process (or auto determined by the client somehow by interrogating the key). Thoughts on approach? I could take a stab at fixing.

I see that the readme.md says to use the classic group, but the online docs do not.
