Does the dispatcher module allow combination like "weighted round robin" algorithm. Or Do we have any similar algorithm ?

Example:

3 of 5 nodes are in better condition so I set them as weight 1 and the other two as weight 2.

Then the dispatcher will round robin between the 3 nodes with weight 1 until all 5 are with the same weight.

That also means that the weight should be dynamic and updated as conditions of the node changes.
