> Key: NIFI-10496
> URL: https://issues.apache.org/jira/browse/NIFI-10496
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core UI
> Reporter: John Wise
> Priority: Minor
> Labels: ControllerService, restore, stateful
>
> 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.
