I expected something entirely different tbh…
A full clone of the measurement, plus the merged lines…
If you remove the merge aggregator does it return a full copy of the measurement?
The current result of clone + merge does not make any sense… is not even valid line protocol… if the clone works properly, then maybe there is a problem with the merge and it might be useful to open an issue on GitHub and/or summon a developer here in this thread.
I’ll try something with static data tomorrow and see if I can replicate the issue
