StatefulSet (Kubernetes)

A StatefulSet is a Kubernetes feature designed for managing applications that require stable, unique identifiers and persistent storage. Unlike regular applications that can be replicated without concern for their state, StatefulSets ensure each instance (or pod) is assigned a consistent name and retains its configuration and data, even if it restarts or scales. This is ideal for databases or applications where data consistency and individual identity are crucial. In essence, StatefulSets provide a way to manage complex applications seamlessly, ensuring reliability and continuity in their operation.
