CPU Share Syncer: Enabling High‑Priority Task CPU Preemption in iQIYI Video Production Kubernetes Clusters

iQIYI’s cpu‑share‑syncer daemon runs on every node, reads a pod’s iqiyi.com/cpu‑share annotation, updates the pod’s cpu.shares after disabling the Kubernetes CPU CFS quota, and lets high‑priority video‑production pods pre‑empt CPU from lower‑priority pods, significantly speeding task execution.
