             Summary: Restore the previous state of referencing components on Parent controller service restart
                 Key: NIFI-10496
                 URL: https://issues.apache.org/jira/browse/NIFI-10496
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Core UI
            Reporter: John Wise


Currently, when stopping and starting a controller service to make any changes, all of its dependent controller services are also stopped.  But restarting it doesn't restore the state of the dependents.  In some situations, we have some of the dependent controller services & processors stopped for a variety of reasons, so don't want/need them to be restarted when the parent is restarted.

Consider adding a "Restore service and referencing components" to the "Scope" options, which would restore the previous state of the parent controller service's referencing components.  That would require storing the state of those when the parent is stopped, then restoring it when it's started again.  If the regular "Service and referencing components" scope is selected, then previous state should be purged.
