    :url: https://pypi.org/project/mysql-connector-python/

.. note::

    The MySQL Connector/Python DBAPI has had many issues since its release,
    some of which may remain unresolved, and the mysqlconnector dialect is
    **not tested as part of SQLAlchemy's continuous integration**.
    The recommended MySQL dialects are mysqlclient and PyMySQL.
