Answer 1

it is doable, though I haven't used Flask at all so I'm not sure about establishing the connection through that. I got it working through Pyramid and submitted a patch to SQLAlchemy (possibly to the wrong repo) here:

https://bitbucket.org/sqlalchemy/sqlalchemy/pull-request/2/added-a-dialect-for-google-app-engines

That has since been replaced and accepted into SQLAlchemy as

I don't think it's made it way to a release though.

There are some issues with Google SQL throwing different exceptions so we had issues with things like deploying a database automatically. You also need to disable connection pooling using NullPool as mentioned in the second patch.

We've since moved to using the datastore through NDB so I haven't followed the progess of these fixes for a while..
