get_node_by_rotation(with_name=True)

Pooling RedisNode and fetch one in turn.

>>> rb.get_node_by_rotation()
('node_1', <redispace.RedisNode object at 0x1376990>)
>>> rb.get_node_by_rotation()
('node_0', <redispace.RedisNode object at 0x1376810>)
>>> rb.get_node_by_rotation()
('node_1', <redispace.RedisNode object at 0x1376990>)
>>> rb.get_node_by_rotation()
('node_0', <redispace.RedisNode object at 0x1376810>)

Parameters:with_name (bool) – the boolean value whether this method returns node with its name or not Returns:the redis node that is in its turn Return type:tuple or RedisNode

value = node.execute('get', 'key')

# is equivalent to:

value = node.client.get('key')
