 The operator can restart StatefulSets when any referenced configuration object (ConfigMap or Secret) changes.
 To enable this, set the `restarter.stackable.tech/enabled` label on the StatefulSet to `true`.

-If a resource is only used for initialization or is hot-reloaded and should not trigger a restart, add the annotation `restarter.stackable.tech/ignore: "true"` to the corresponding ConfigMap or Secret:
+These annotations can be added if the restarter is enabled on a StatefulSet, but some ConfigMaps or Secrets should be excluded from triggering a restart. `*` can be replaced with any value and is only used to make the annotation key unique.

+If a ConfigMap or Secret is only used for initializing a StatefulSet or contains data which can be hot-reloaded, add the label `restarter.stackable.tech/ignore: "true"` to avoid unnecessary restarts of the StatefulSet pods:
