             Summary: Add exclusion filters to SiteToSiteProvenanceReportingTask
                 Key: NIFI-4768
                 URL: https://issues.apache.org/jira/browse/NIFI-4768
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Matt Burgess


Although the SiteToSiteProvenanceReportingTask has filters for which events, components, etc. to capture, it is an inclusive filter, meaning if a filter is set, only those entities' events will be sent. However it would be useful to also have an exclusionary filter, in order to capture all events except a few. 

One particular use case is a sub-flow that processes provenance events, where the user would not want to process provenance events generated by components involved in the provenance-handling flow itself. In this fashion, for example, if the sub-flow is in a process group (PG), then the user could exclude the PG and the Input Port sending events to it, thereby allowing the sub-flow to process all other events except those involved with the provenance-handling flow itself.
