John Wise updated NIFI-10496:
-----------------------------
Description:
Currently, when stopping and starting a controller service to make any changes,
all of its dependent controller services and processors are also stopped. In
some situations, we have some of the dependent controller services & processors
stopped for a variety of reasons, so don't want/need those 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.
