------------------------------
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.
