Mark Payne commented on NIFI-40:
--------------------------------
Unlikely. This was one of the first Jiras created for the project and has seen
no traction. I've seen basically nobody asking for this functionality. We often
see users exporting the provenance for longer-term storage via the
SiteToSiteProvenanceReportingTask and pushing to something like Elasticsearch,
which would expose more powerful query capabilities as well as longer-term
storage typically.

> Key: NIFI-40
> URL: https://issues.apache.org/jira/browse/NIFI-40
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> Reporter: Mark Payne
> Priority: Major
>
> Prov Repo should return a StoredProvenanceRecord object that provides a
> StorageLocation object and the Prov Record itself. This StorageLocation is a
> marker interface; specific Prov Repo can create their own implementations to
> lookup records. Attempt to lookup by Location will throw
> IllegalArgumentException if Location is not valid for that repo.
> Compared to existing Persistent Prov Repo, also will need to make compression
> better/seekable, or reading the records will take far too long to be very
> usable.
