Automatic merge from submit-queue (batch tested with PRs 48043, 48200, 49139, 36238, 49130) Implement equivalence cache by caching and re-using predicate result The last part of #30844, I opened a new PR instead of overwrite the old one because we changed some basic assumption by allowing invalidating equivalence cache item by individual predicate. The idea of this PR is based on discussion in https://github.com/kubernetes/kubernetes/issues/32024 - [x] Pods belong to same controllerRef considered to be equivalent - [x] ` podFitsOnNode` will use cached predicate result if it's available - [x] Equivalence cache will be updated when if a fresh new predicate is done - [x] `factory.go` will invalid specific predicate cache(s) based on the object change - [x] Since `schedule` and `bind` are async, we need to optimistically invalid affected cache(s) before `bind` - [x] Fully unit test of affected files - [x] e2e test to verify cache update/invalid workflow - [x] performance test results - [x] Some nits fixes related but expected to result in `needs-rebase` so they are split to: #36060 #35968 #37512 cc @wojtek-t @davidopp |
