- DataStore allows to specify a DataStore that should be used to store the Kubernetes data for the given Tenant Control Plane.
- This parameter is optional and acts as an override over the default one which is used by the Kamaji Operator.
+ DataStore specifies the DataStore that should be used to store the Kubernetes data for the given Tenant Control Plane.
+ When Kamaji runs with the default DataStore flag, all empty values will inherit the default value.
+ By leaving it empty and running Kamaji with no default DataStore flag, it is possible to achieve automatic assignment to a specific DataStore object.

  Migration from one DataStore to another backed by the same Driver is possible. See: https://kamaji.clastix.io/guides/datastore-migration/
  Migration from one DataStore to another backed by a different Driver is not supported.
