Hi there,

after closing #100 and bringing in crate/crate-python#391, we may want to look at SQLAlchemy support for Python asyncio. Currently, trying to invoke the CrateDB driver like postgresql+asyncpg:// croaks like

>>> from sqlalchemy.ext.asyncio import create_async_engine
>>> create_async_engine("crate+asyncpg://crate@localhost/test")
sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:crate.asyncpg

So, the CrateDB dialect will have to be accompanied by a special asyncio mediation layer, like dialects/postgresql/asyncpg.py.

With kind regards,
Andreas.
