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.
