---------------------------------
Summary: Allow parameters to reference controller services
Key: NIFI-9895
URL: https://issues.apache.org/jira/browse/NIFI-9895
Project: Apache NiFi
Issue Type: Improvement
Reporter: Tamas Palfy
Currently processors cannot reference controller services through parameters.
While this has security reasons (apart from the technical challenges), flow
definition reusability would be greatly enhanced if users could predefine
controller services and control which one to use (if at all) through
parameters. This way the flow itself could be treated as static and all aspects
of the configuration could be managed without the need to change it.
Security concerns need to be carefully handled whenever the parameter
(referencing a controller service), or the processor property (using such a
parameter), changes.
