The current scheduler plugin implementation assumes that a scheduler “algorithm” needs to be used only when a pod needs to be scheduled (and not deleted/updated). It would be useful to generalize this with added support for letting the scheduler know about delete/update events as well. One example of where this would be very useful would be to integrate better with external/stateful schedulers/resource managers (e.g YARN). Instead of calling into the scheduler algorithm with a pod definition, maybe a pattern similar to what is used in the kubelet could be used ? ( “PodUpdate”/“PodOperation” ). Thoughts?
