What is the purpose of StatefulSet in Kubernetes?

StatefulSet in Kubernetes is designed to manage the state and lifecycle of sets of pods that require unique, stable identifiers and persistent storage.

Key features of StatefulSet:

• Each pod receives a unique name with an index (e.g., web-0, web-1).
• Supports ordered creation, updating, and deletion of pods.
• Ensures stable network identities and persistent volumes for each pod.

This is useful for applications that require state preservation, such as databases, cache services, and distributed systems.
