[release-4.20] OCPBUGS-114730: Use Add() instead of AddRateLimited() for routine Profile enqueues - #1620
Conversation
Change 1: workqueue.DefaultTypedControllerRateLimiter's AddRateLimited() draws from a single 10qps/burst-100 token bucket shared by every item in the queue, regardless of kind or key. Cascade/trigger enqueues (Pod/Node change to Profile update, per-Profile bootstrap loop, initial bootstrap event) used AddRateLimited() for ordinary enqueuing rather than error retries. During a burst of ~100 nodes joining, this exhausted the shared bucket, delaying later Profile syncs by minutes even though they were never dropped, just queued behind the backlog. Switch these call sites to Add(), which is unthrottled and still deduped by key via the delaying queue's dirty set. Keep AddRateLimited() only for its intended purpose: the retry-after- sync()-error path, where per-key exponential backoff is correct. Change 2: validateTunedCRs() called UpdateStatus() on every Tuned CR on every invocation, even when the computed status conditions were identical to what's already stored. Compare the newly computed status against the cached copy with reflect.DeepEqual() and skip the UpdateStatus() call when nothing semantically changed. Resolves: OCPBUGS-105458
