* Improve scheduler performance of MatchInterPodAffinity predicate. ([#57476](https://github.com/kubernetes/kubernetes/pull/57476), [@misterikkit](https://github.com/misterikkit))
* Improve scheduler performance of MatchInterPodAffinity predicate. ([#57477](https://github.com/kubernetes/kubernetes/pull/57477), [@misterikkit](https://github.com/misterikkit))

  * New SchedulerExtender enables users to implement custom
out-of-(the-scheduler)-process scheduling predicates and priority functions,
for example to schedule pods based on resources that are not directly managed

* Performance of the affinity/anti-affinity predicate for the default scheduler has been significantly improved. ([#62211](https://github.com/kubernetes/kubernetes/pull/62211), [@bsalamat](https://github.com/bsalamat))

    *   The VolumeScheduling feature gate must also be enabled on kube-scheduler and kube-controller-manager components.
    *   The NoVolumeNodeConflict predicate has been removed.  For non-default schedulers, update your scheduler policy.
    *   The CheckVolumeBinding predicate must be enabled in non-default schedulers. ([#55039](https://github.com/kubernetes/kubernetes/pull/55039),[ @msau42](https://github.com/msau42))

### Scheduling

- Only validate duplication of the RequestedToCapacityRatio custom priority and allow other custom predicates/priorities ([#84646](https://github.com/kubernetes/kubernetes/pull/84646), [@liu-cong](https://github.com/liu-cong))

* Add error count and time-taken metrics for storage operations such as mount and attach, per-volume-plugin. ([#50036](https://github.com/kubernetes/kubernetes/pull/50036), [@wongma7](https://github.com/wongma7))
