------------------------------------
Summary: Consider a ControlNiFi processor
Key: NIFI-4200
URL: https://issues.apache.org/jira/browse/NIFI-4200
Project: Apache NiFi
Issue Type: New Feature
Components: Extensions
Reporter: Pierre Villard
We frequently see on the mailing list the need to start/stop a processor based
on incoming flow files. At the moment, that's something that can be scripted or
that can be done using multiple InvokeHttp processors but it requires a bit of
work.
Even though it is not really in the "NiFi way of thinking", it would be
interesting to have a processor with the following parameters:
- NiFi REST API URL
- Username
- Password
- Processor/Processor Group UUID (with expression language)
- Action to perform (START, STOP, START/STOP, STOP/START)
- Sleep duration (between the START and STOP calls when action is START/STOP,
or STOP/START)
That would be helpful in use cases like:
- start a workflow based on another workflow
- start a processor not accepting incoming relationship based on a flow file
- restart a processor to "refresh" its configuration when the processor relies
on configuration files that could be changed
- have a "start once" behavior
