--------------------------------
Summary: When calculating lineage for a FlowFile, should provide a
mechanism for starting with a particular event instead of FlowFile UUID
Key: NIFI-2447
URL: https://issues.apache.org/jira/browse/NIFI-2447
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework, Core UI
Reporter: Mark Payne
Fix For: 1.1.0
Currently, whenever a user clicks the lineage button in the Provenance UI, we
have the ID of the Provenance Event that the user wants to generate a lineage
for. However, we pass in only the UUID of the FlowFile.
If we pass in the Event ID instead, we are able to determine the Lineage Start
Date from that event, which is very efficient. We can then search for events in
the lineage with that start date. Currently, we search the entirety of the
Provenance Repository in order to create a lineage, but this is very
inefficient.
