Consistent Hashing Algorithm: Principles, Advantages, and Applications

Consistent hashing maps both servers and keys onto a virtual hash ring, allowing keys to be assigned to the nearest clockwise server, which minimizes data movement during node addition or removal, improves load distribution with virtual nodes, and is widely used in distributed caching and load balancing systems.

Using Tencent Cloud EKS Virtual Nodes to Solve CronJob Isolation and Scheduling Challenges

By offloading thousands of short‑lived CronJob pods to Tencent Cloud EKS serverless virtual nodes, Zuoyebang isolated them from online services, eliminated IP waste, achieved millisecond‑level parallel scheduling and sub‑3‑second startup, freed 10 % of cluster resources and cut scheduling costs by roughly 70 % while markedly improving cluster stability.
