Description
Does Ray support affinity scheduling for tasks or actors, like pod affinity for k8s?
Allows a group of different tasks to run on the same node and share Object storage memory, reducing grpc transfers.
Use case
In the ray data scenario, if there are multiple Physical operators of the ActorPoolMapOperator type, By using task affinity, objects generated by the parent Operator task can be directly consumed by tasks of the current Operator, reducing Object transfer across nodes.
