Subject Providing a uuid for a FlowFile
Date Sun, 04 Dec 2016 09:44:03 GMT

We have been producing UUIDs for all messages flowing through Activity
Stream that we call StreamId and they are of the same UUID version as NiFi
uses for FlowFiles.

I tried to set the uuid attribute on "first contact" (in port) for NiFI but
it still, understandably, generates it's own UUID.

Is there a way to have NiFi accept an external UUID or is it an fundimental
requirement of NiFi to generate on for it self?

This is not important as I can set this as another attribute but I'm just
looking to simplify things a bit :) for us and our tracability.
