// The producer of these objects can decide which approach is more suitable.

All in a way that provided the best development experience for all the developers.

  // The other mode is "Ephemeral". In this mode, volumes are defined inline inside the pod spec
  // with CSIVolumeSource and their lifecycle is tied to the lifecycle of that pod.
