@jtstorck correct, the position in the queue is per-node. It is not
intended to be unique and is not an identifier. Rather, it shows -for this node
- how far is this FlowFile from the top of the queue. I don't believe we want
to make the value unique across the cluster. I do believe we should add a
column for which node a FlowFile is on, though. But not in scope for this JIRA.
Please feel free to raise one if you would like.
