StatefulSet
Workload controller managing stateful applications requiring unique network IDs and ordered volume provisioning.
Mechanism & Definition
A Kubernetes workload API object used to manage stateful applications (e.g. databases, distributed caches). Unlike Deployments, StatefulSets maintain a sticky identity for each Pod (ordinal index `pod-0`, `pod-1`), matching PersistentVolumeClaims, and performing ordered deployment/deletion.
