.. dialect:: mysql+asyncmy
    :name: asyncmy
    :dbapi: asyncmy
    :connectstring: mysql+asyncmy://user:password@host:port/dbname[?key=value&key=value...]
    :url: https://github.com/long2ice/asyncmy

Using a special asyncio mediation layer, the asyncmy dialect is usable
as the backend for the :ref:`SQLAlchemy asyncio <asyncio_toplevel>`
extension package.

This dialect should normally be used only with the
:func:`_asyncio.create_async_engine` engine creation function::

    from sqlalchemy.ext.asyncio import create_async_engine

    engine = create_async_engine(
        "mysql+asyncmy://user:pass@hostname/dbname?charset=utf8mb4"
    )
