  Depending on the value returned from QueueingHintFn, the scheduling queue changes how it queues each Pod:
  - if more than one QueueingHintFn returns QueueImmediately, it queues Pod to activeQ.

smaller chunks. A client can specify a limit to the number of results to return. If more results exist, a token is returned that allows the client to continue the previous list call repeatedly until all results are retrieved.  The resulting list is identical to a list call that does not perform chunking, thanks to capabilities provided by etcd3.  This allows the server to use less memory and CPU when very large lists are returned. This feature is gated as APIListChunking and is not enabled by default....

- Kube-scheduler implemented scheduling hints for the `NodeResourceFit` plugin. The scheduling hints allowed the scheduler to only retry scheduling a Pod that had been previously rejected by...

- Added a return value to `QueueingHint` to indicate an error. If `QueueingHint` returns an error,
  the scheduler logs it and treats the event as a `QueueAfterBackoff` so that
