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, for backward compatibility
:param str database: database to use
:param str db: alias of database, for backward compatibility
: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 False on Python 2 and True on Python 3
so that you can always get python `str` object by default.
:param str charset:
If supplied, the connection character set will be changed
to this character set.
On Python 2, this option changes default value of `use_unicode`
option from False to True.
: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 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.
