Mark Payne commented on NIFI-13929:
-----------------------------------
Given the simple flow above (GenerateFlowFile -> UpdateAttribute ->
UpdateCounter) I would expect to see 3 events (CREATE / ATTRIBUTES_MODIFIED /
DROPPED). But when I query provenance for one of the UUIDs of a flowfile that
was processed, I see a huge number of events.
> Many duplicates for Provenance Events when running Stateless flow with
> multiple threads

> When running a flow using the Stateless Execution Engine, we see it making a
> huge number of duplicates in the provenance repository. This results in poor
> performance, as well as very incorrect Provenance.
