Each node is represented by a pair (hostname, port). ``min_other_sentinels`` defined a minimum number of peers for a sentinel. When querying a sentinel, if it doesn't meet this threshold, responses from that sentinel won't be considered valid. ``sentinel_kwargs`` is a dictionary of connection arguments used when connecting to sentinel instances. Any argument that can be passed to a normal Redis connection can be specified here. If ``sentinel_kwargs`` is not specified, any socket_timeout and socket_keepalive options specified in ``connection_kwargs`` will be used. ``connection_kwargs`` are keyword arguments that will be used when establishing a connection to a Redis server.
