        To specify a retry policy for specific errors, first set
        `retry_on_error` to a list of the error/s to retry on, then set
        `retry` to a valid `Retry` object.
        To retry on TimeoutError, `retry_on_timeout` can also be set to `True`.
        Nz'username' and 'password' cannot be passed along with 'credential_provider'. Please provide only one of the following arguments:

        Register a callback to be called when the connection is established either
        initially or reconnected.  This allows listeners to issue commands that
        are ephemeral to the connection, for example pub/sub subscription or

        a weak reference.

        Args:
            ssl_keyfile: Path to an ssl private key. Defaults to None.
            ssl_certfile: Path to an ssl certificate. Defaults to None.
            ssl_cert_reqs: The string value for the SSLContext.verify_mode (none, optional, required). Defaults to "required".
            ssl_ca_certs: The path to a file of concatenated CA certificates in PEM format. Defaults to None.
            ssl_ca_data: Either an ASCII string of one or more PEM-encoded certificates or a bytes-like object of DER-encoded certificates.
            ssl_check_hostname: If set, match the hostname during the SSL handshake. Defaults to False.
            ssl_ca_path: The path to a directory containing several CA certificates in PEM format. Defaults to None.
            ssl_password: Password for unlocking an encrypted private key. Defaults to None.

            ssl_validate_ocsp: If set, perform a full ocsp validation (i.e not a stapled verification)
            ssl_validate_ocsp_stapled: If set, perform a validation on a stapled ocsp response
            ssl_ocsp_context: A fully initialized OpenSSL.SSL.Context object to be used in verifying the ssl_ocsp_expected_cert
            ssl_ocsp_expected_cert: A PEM armoured string containing the expected certificate to be returned from the ocsp verification service.
            ssl_min_version: The lowest supported SSL version. It affects the supported SSL versions of the SSLContext. None leaves the default provided by ssl module.
            ssl_ciphers: A string listing the ciphers that are allowed to be used. Defaults to None, which means that the default ciphers are used. See https://docs.python.org/3/library/ssl.html#ssl.SSLContext.set_ciphers for more information.

    Create a connection pool. ``If max_connections`` is set, then this
    object raises :py:class:`~redis.exceptions.ConnectionError` when the pool's
    limit is reached.

    By default, TCP connections are created unless ``connection_class``
    is specified. Use class:`.UnixDomainSocketConnection` for
    unix sockets.

    Any additional keyword arguments are passed to the constructor of
    ``connection_class``.

        Return a connection pool configured from the given URL.

        For example::

            redis://[[username]:[password]]@localhost:6379/0
            rediss://[[username]:[password]]@localhost:6379/0
            unix://[username@]/path/to/socket.sock?db=0[&password=password]

        Three URL schemes are supported:

        - `redis://` creates a TCP socket connection. See more at:
          <https://www.iana.org/assignments/uri-schemes/prov/redis>
        - `rediss://` creates a SSL wrapped TCP socket connection. See more at:
          <https://www.iana.org/assignments/uri-schemes/prov/rediss>
        - ``unix://``: creates a Unix Domain Socket connection.

        The username, password, hostname, path and all querystring values
        are passed through urllib.parse.unquote in order to replace any
        percent-encoded values with their corresponding characters.

        There are several ways to specify a database number. The first value
        found will be used:

            1. A ``db`` querystring option, e.g. redis://localhost?db=0
            2. If using the redis:// or rediss:// schemes, the path argument
               of the url, e.g. redis://localhost/0
            3. A ``db`` keyword argument to this function.

        If none of these options are specified, the default db=0 is used.

        All querystring options are cast to their appropriate Python types.
        Boolean arguments can be specified with string values "True"/"False"
        or "Yes"/"No". Values that cannot be properly cast cause a
        ``ValueError`` to be raised. Once parsed, the querystring arguments
        and keyword arguments are passed to the ``ConnectionPool``'s
        class initializer. In the case of conflicting arguments, querystring
        arguments always win.

    Thread-safe blocking connection pool::

        >>> from redis.client import Redis
        >>> client = Redis(connection_pool=BlockingConnectionPool())

    It performs the same function as the default
    :py:class:`~redis.ConnectionPool` implementation, in that,
    it maintains a pool of reusable connections that can be shared by
    multiple redis clients (safely across threads if required).

    The difference is that, in the event that a client tries to get a
    connection from the pool when all of connections are in use, rather than
    raising a :py:class:`~redis.ConnectionError` (as the default
    :py:class:`~redis.ConnectionPool` implementation does), it
    makes the client wait ("blocks") for a specified number of seconds until
    a connection becomes available.

    Use ``max_connections`` to increase / decrease the pool size::

        >>> pool = BlockingConnectionPool(max_connections=10)

    Use ``timeout`` to tell it either how many seconds to wait for a connection
    to become available, or to block forever:

        >>> # Block forever.
        >>> pool = BlockingConnectionPool(timeout=None)

        >>> # Raise a ``ConnectionError`` after five seconds if a connection is
        >>> # not available.
        >>> pool = BlockingConnectionPool(timeout=5)

        Get a connection, blocking for ``self.timeout`` until a connection
        is available from the pool.

        If the connection returned is ``None`` then creates a new connection.
        Because we use a last-in first-out queue, the existing connections
        (having been returned to the pool after the initial ``None`` values
        were added) will be returned before ``None`` values. This means we only
        create new connections when we need to, i.e.: the actual number of
        connections will only increase in response to demand.
