.. dialect:: mysql+mariadbconnector
    :name: MariaDB Connector/Python

    :url: https://pypi.org/project/mariadb/

Driver Status
-------------

MariaDB Connector/Python enables Python programs to access MariaDB and MySQL
databases using an API which is compliant with the Python DB API 2.0 (PEP-249).
It is written in C and uses MariaDB Connector/C client library for client server
communication.

Note that the default driver for a ``mariadb://`` connection URI continues to
be ``mysqldb``. ``mariadb+mariadbconnector://`` is required to use this driver.
