@mosermw good call. We should be able to get #1475 merged pretty easily, I
think. Then can rebase my PR.
> Provide a newly refactored provenance repository

>
> The Persistent Provenance Repository has been redesigned a few different
> times over several years. The original design for the repository was to
> provide storage of events and sequential iteration over those events via a
> Reporting Task. After that, we added the ability to compress the data so that
> it could be held longer. We then introduced the notion of indexing and
> searching via Lucene. We've since made several more modifications to try to
> boost performance.
> At this point, however, the repository is still the bottleneck for many flows
> that handle large volumes of small FlowFiles. We need a new implementation
> that is based around the current goals for the repository and that can
> provide better throughput.
