Oleg,

The experience around the NiFi provenance events today is around a
"nifi cluster".  When you query that cluster it is asking all nodes
the question.

In each node it is true you can configure multiple storage points for
provenance events.  The reason you would do this is if you want to
distribute the writes to multiple physical partitions.  It is still
one logical provenance store but now you can stripe the writes across
multiple points.  This is important for sure at super high rates.
Same is true of content repository.

Thanks
Joe
