/**
* StatefulSet is the workload API object used to manage stateful applications.
*
* Manages the deployment and scaling of a set of Pods, and provides guarantees
* about the ordering and uniqueness of these Pods.
*
* Like a Deployment, a StatefulSet manages Pods that are based on an identical
* container spec. Unlike a Deployment, a StatefulSet maintains a sticky identity
* for each of their Pods. These pods are created from the same spec, but are not
* interchangeable: each has a persistent identifier that it maintains across any
* rescheduling.
*
* If you want to use storage volumes to provide persistence for your workload, you
* can use a StatefulSet as part of the solution. Although individual Pods in a StatefulSet
* are susceptible to failure, the persistent Pod identifiers make it easier to match existing
* volumes to the new Pods that replace any that have failed.
*
*
Using StatefulSets
*
* StatefulSets are valuable for applications that require one or more of the following.
*
*
* - Stable, unique network identifiers.
* - Stable, persistent storage.
* - Ordered, graceful deployment and scaling.
* - Ordered, automated rolling updates.
