Some neat stuff here, @markap14 . I noticed you changed a couple of the
same files as PR #1475. Since #1475 is almost complete, it would be nice to
commit that first. Merging that into this PR shouldn't be bad at all, and if
we're lucky it will still apply cleanly!
> 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.
