Order in which we consume from queues.
Can be either string alias, or a cycle strategy class
- ``round_robin``
:class:`~kombu.utils.scheduling.round_robin_cycle``
Make sure each queue has an equal opportunity to be consumed from.
- ``sorted``
:class:`~kombu.utils.scheduling.sorted_cycle`.
Consume from queues in alphabetical order.
If the first queue in the sorted list always contains messages,
then the rest of the queues will never be consumed from.
- ``priority``
:class:`~kombu.utils.scheduling.priority_cycle`.
Consume from queues in original order, so that if the first
queue always contains messages, the rest of the queues
in the list will never be consumed from.
The default is to consume from queues in round robin.
