---------------------------------
Summary: Drop events disordering
Key: NIFI-4638
URL: https://issues.apache.org/jira/browse/NIFI-4638
Project: Apache NiFi
Issue Type: Bug
Reporter: Omer Hadari
Drop events that are generated by terminated relationships alongside other
event types are sometimes registered before them. This happens since the drop
event’s timestamp is lower by a millisecond compared to the timestamp of the
other event, even though the ordinal is higher. This causes the lineage graph
to look as if the other event comes out of the drop event.
The one millisecond difference and the fact that this bug is sporadic suggests
a rollover to the next millisecond when registering the event before the drop
event.
For example this was encountered in the split json processor, when the original
flowfile receives a fragment count and then dropped. This could be a bug in the
processor itself, though it seems to be more generic.
