Mark Payne commented on NIFI-1116:
----------------------------------

[~joewitt] - I'm not sure that I understand how this would work. The lineage 
view is in fact a chronological view of what happened and is not related to 
different components on the graph. Changing the placement on the graph so that 
it appears next to some other event I think is less intuitive. Especially if we 
consider that the same processor could potentially operate on the data multiple 
times.

I do understand the initial intuition that the event should be located next to 
other events that happened by the same component, but the Lineage view is 
intended to be chronological, and I think if we tried to change something like 
that, it would become quasi-chronological and lead to more confusion.

> If you replay a flowfile there is now a nice/clear REPLAY event which is 
> great.  But where it gets placed on the graph is surprising.  I believe it 
> should extend from the event for the component that processed that event 
> originally when possible.  It appears to use timing as the ordering mechanism 
> on the graph.  Can we make this better/more intuitive?
> Thanks
