             Summary: Need a FETCH_CONTENT Provenance Event
                 Key: NIFI-7
                 URL: https://issues.apache.org/jira/browse/NIFI-7
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Matt Gilman


This event should be used in lieu of a RECEIVE event when we are modifying the content based on data retrieved from an external source. The RECEIVE event is intended to denote the start of a FlowFile's Lineage. However, we often have Processors that fetch a listing of Files from an external service and then have a subsequent Processor pull the content. RECEIVE in this case breaks things because we can't indicate that we are RECEIVING a FlowFile if we already have the FlowFile. CONTENT_MODIFIED is better but doesn't indicate that we are receiving the data from an external source or what that external source is.

Propose we introduce FETCH_CONTENT Provenance Type that allows the ability to specify 1 or more URIs from which the content was fetched.
