I’ve looked at quart and it looks interesting but is there much point to running an async webserver for APIs mainly reliant on db-access if we use SQLAlchemy for database connections? I’m under the impression that since the db stuff still is sync/blocking we won’t win much by running an asgi server instead of WSGI.
Give peewee-async as shot if you'd like async DB access as well. https://peewee-async.readthedocs.io/en/latest/ Looks like Gino is a new project trying to bake asyncio ORM on top of sqlalchemy core: https://github.com/fantix/gino
While interesting for greenfield development and experiments I'd say that it's most often a to big of a leap to change both ORM (with all db-access-code) and microframework at the same time for a well established project at 20KLOC+.
