When order message is needed, users need to provide a message queue selector to make sure that the messages which has the same shading key should be sent to the same message queue.

Actually this is a very common scenario with a common solutions, say consistent hashing.

We should provide a handy selector for them to easily do that, what they only need to provide is a shading key.

A consistent hash selector will meet most of the user's need.
