This module implements connections for MySQLdb. Presently there is
only one class: Connection. Others are unlikely. However, you might
want to make your own subclasses. In most cases, you will probably
override Connection.default_cursor with a non-standard Cursor class.

        Create a connection to the database. It is strongly recommended
        that you only use keyword parameters. Consult the MySQL C API
        documentation for more information.

        :param str host:        host to connect
        :param str user:        user to connect as
        :param str password:    password to use
        :param str passwd:      alias of password (deprecated)
        :param str database:    database to use
        :param str db:          alias of database (deprecated)
        :param int port:        TCP/IP port to connect to
        :param str unix_socket: location of unix_socket to use
        :param dict conv:       conversion dictionary, see MySQLdb.converters
        :param int connect_timeout:
            number of seconds to wait before the connection attempt fails.

        :param bool compress:   if set, compression is enabled
        :param str named_pipe:  if set, a named pipe is used to connect (Windows only)
        :param str init_command:
            command which is run once the connection is created

        :param str read_default_file:
            file from which default client values are read

        :param str read_default_group:
            configuration group to use from the default file

        :param type cursorclass:
            class object, used to create cursors (keyword only)

        :param bool use_unicode:
            If True, text-like columns are returned as unicode objects
            using the connection's character set. Otherwise, text-like
            columns are returned as bytes. Unicode objects will always
            be encoded to the connection's character set regardless of
            this setting.
            Default to True.

        :param str charset:
            If supplied, the connection character set will be changed
            to this character set.

        :param str auth_plugin:
            If supplied, the connection default authentication plugin will be
            changed to this value. Example values:
            `mysql_native_password` or `caching_sha2_password`

        :param str sql_mode:
            If supplied, the session SQL mode will be changed to this
            setting.
            For more details and legal values, see the MySQL documentation.

        :param int client_flag:
            flags to use or 0 (see MySQL docs or constants/CLIENTS.py)

        :param bool multi_statements:
            If True, enable multi statements for clients >= 4.1.
            Defaults to True.

        :param str ssl_mode:
            specify the security settings for connection to the server;
            see the MySQL documentation for more details
            (mysql_option(), MYSQL_OPT_SSL_MODE).
            Only one of 'DISABLED', 'PREFERRED', 'REQUIRED',
            'VERIFY_CA', 'VERIFY_IDENTITY' can be specified.

        :param dict ssl:
            dictionary or mapping contains SSL connection parameters;
            see the MySQL documentation for more details
            (mysql_ssl_set()).  If this is set, and the client does not
            support SSL, NotSupportedError will be raised.

        :param bool local_infile:
            enables LOAD LOCAL INFILE; zero disables

        :param bool autocommit:
            If False (default), autocommit is disabled.
            If True, autocommit is enabled.
            If None, autocommit isn't set and server default is used.

        :param bool binary_prefix:
            If set, the '_binary' prefix will be used for raw byte query
            arguments (e.g. Binary). This is disabled by default.

        There are a number of undocumented, non-standard methods. See the
        documentation for the MySQL C API for some hints on what they do.
