Michael Moser commented on NIFI-1018: ------------------------------------- I wonder if the new StateManager could be leveraged in any way? Can Controller Services access the StateManager? Can FlowFile references be stored in the StateManager in such a way that it could be used in a ProvenanceReporter? > Allow ControllerServices access to ProvenanceReporter > ----------------------------------------------------- > > Key: NIFI-1018 > URL: https://issues.apache.org/jira/browse/NIFI-1018 > Project: Apache NiFi > Issue Type: Improvement > Reporter: Brandon DeVries > Assignee: Michael Moser > > Currently we maintain a provenance trail for all files flowing through NiFi > Processors. However, if a ControllerService uses some data set it generally > just loads it from disk after it is fetched using a normal NiFi flow. > However, this breaks the provenance trail for the data set... there is no way > (in provenance terms) of knowing what data set the ControllerService is using > or when it was loaded. By giving ControllerServices access to the > ProvenanceReporter, they can acknowledge "receipt" of a data set, so the > provenance trail from pull to use is maintained. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
