+##### PersistentVolumeClaims 
+
+Often times a successful rollback of a failed statefulset upgrade will require restoring snapshots of persistent volumes. Snapshots can occur via a CSI snapshot controller using the `VolumeSnapshot` and `VolumeSnapshotClass` resources. One such example of a CSI snapshot controller is [external-snapshotter](https://github.com/kubernetes-csi/external-snapshotter).

 ##### Headless service 
 A big consideration with [type 1 statefulsets](#type-1) is that traffic hits pods directly instead of hitting a k8s service when using a headless service. 
 There are traffic management considerations when using headless services. ie traffic is not always captured/processed using service mesh solutions such as Istio.
