Capture the Download event in provenance?

andrewg — Tue, 21 Apr 2026 12:35:12 GMT

NiFi has a a special role requirement to allow/disallow downloading the content from the provenance view. However, is it possible to record the fact that someone downloaded the contents of an event?

Such information is already captured. Doing so creates a 'SEND' event and in the details of the provenance event we provide information on who (if it is secured) actually did the download.

Is there a way to tell this SEND event from 'regular flow' SEND events? We have people asking about fishing out this event specifically.

Replay would probably be the same implementation.

The idea for making 'DOWNLOAD' its own event has been in play for a while.https://issues.apache.org/jira/browse/NIFI-10 We have sort of pushed this as we want to be really conservative making new event types. For REPLAY I think we call it a CLONE today (i think). If you'd like to revive that discussion and add the case for replay please go ahead and comment on that ticket.

For the record, this made it into the 0.4.0 release now. Thanks everyone!
