For this kind of thing we'd not have a SQLAlchemy "dialect", there are 
potentially ways that some parts of the SQLAlchemy ORM can be made to integrate 
with non-relational backends, specifically unit of work hooks that can take 
advantage of the ability to track changes to a Python object and "flush" them 
out to a backend.   But even there, the main advantage would be that an 
application could integrate across a relational and non-relational backend 
simultaneously - if you were only talking to a NoSQL db, you'd probably use 
some other package.

If I had unlimited development resources, I might break out that part of the 
SQLAlchemy ORM that does "object instrumentation" and change tracking into it's 
own product, which could then be used in different ways.   If for no other 
reason than to not have any packages with the word "SQL" in them if we aren't 
actually using any relational DBs :).

For the querying side of things and obviously the "schema" side, there's no 
overlap between SQLAlchemy and such a system.
