Optimizing Flink Task Scheduling on a Kubernetes Standalone Cluster for Balanced Resource Utilization

This article analyzes the uneven task distribution problem in a Flink job running on a Kubernetes standalone cluster with 35 TaskManagers and 140 slots, proposes slot‑sharing‑group prioritization and delayed scheduling strategies, and demonstrates how these optimizations achieve more balanced CPU load and reduced data backlog.
