Review comment:
In the GetMongo processor there's an option to "Send Empty Result"
instead of creating another relationship, what about adding this option instead
for symmetry. This option sends an empty JSON object out the success
relationship if there's no result.
I had the same issue with GetMongo and the "Send Empty Result" fixed my
issue.
