Describes how Xiaohongshu uses Karmada to federate stateful workloads (search, ads, recommendation) across multiple Kubernetes clusters to avoid single-cluster capacity limits. Explains design and implementation of scheduling and deployment capabilities for stateful service replicas that each maintain independent index-table state, enabling transparent scaling without manual workload migration.
