Return a connection pool configured from the given URL.
For example::
redis://[:password]@localhost:6379/0
rediss://[:password]@localhost:6379/0
unix://[:password]@/path/to/socket.sock?db=0
Three URL schemes are supported:
- ```redis://``
<http://www.iana.org/assignments/uri-schemes/prov/redis>`_ creates a
normal TCP socket connection
- ```rediss://``
<http://www.iana.org/assignments/uri-schemes/prov/rediss>`_ creates a
SSL wrapped TCP socket connection
- ``unix://`` creates a Unix Domain Socket connection
There are several ways to specify a database number. The parse function
will return the first specified option:
1. A ``db`` querystring option, e.g. redis://localhost?db=0
2. If using the redis:// scheme, the path argument of the url, e.g.
redis://localhost/0
3. The ``db`` argument to this function.
If none of these options are specified, db=0 is used.
The ``decode_components`` argument allows this function to work with
percent-encoded URLs. If this argument is set to ``True`` all ``%xx``
escapes will be replaced by their single-character equivalents after
the URL has been parsed. This only applies to the ``hostname``,
``path``, and ``password`` components.
Any additional querystring arguments and keyword arguments will be
passed along to the ConnectionPool class's initializer. The querystring
arguments ``socket_connect_timeout`` and ``socket_timeout`` if supplied
are parsed as float values. The arguments ``socket_keepalive`` and
``retry_on_timeout`` are parsed to boolean values that accept
True/False, Yes/No values to indicate state. Invalid types cause a
``UserWarning`` to be raised. In the case of conflicting arguments,
querystring arguments always win.
