I don't think you meant to leave this test as is without @Ignore. It
certainly takes time to complete.
> Provide a newly refactored provenance repository
> ------------------------------------------------
>
> Key: NIFI-3356
> URL: https://issues.apache.org/jira/browse/NIFI-3356
> Project: Apache NiFi
> Issue Type: Task
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Mark Payne
> Fix For: 1.2.0
>
>
> 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.
