Joseph Witt commented on NIFI-99:
---------------------------------
Sort of. The flow design/monitoring mechanism via interactive queues
definitely helps. But the original intent of the ticket was around the notion
of a user interacting with the provenance trail of a given object. The general
idea of provenance was the ability to 'look back at what happened' but this
case covers slower flows whereby one might be looking at the provenance trail
of something which isn't finished in its total journey through the flow. In
such a case we want to be able to go from provenance (historical knowledge) to
current (where that object is right now and what are its content/attributes).
That said, interactive queue has definitely made this way less necessary.

> To recreate the situation here is a good sample flow:
> - GetFile to pickup line oriented text data
> - Split such that it results in 2 or more splits
> - Send to a disabled MergeContent
> Start the flow (with Merge disabled).
> Then look at the provenance trail.
> You can see the child flow file objects in the provenance graph but you
> cannot click on them to view details or content.
> Basically to the greatest extent possible anywhere there is a node on the
> prov graph one should be able to right-click and see the attributes/etc.
