See more at: - ``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.

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.

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.
