             Summary: Implement Provenance Query Language -- requires refactoring of Prov Repo API / Implementations
                 Key: NIFI-40
                 URL: https://issues.apache.org/jira/browse/NIFI-40
             Project: Apache NiFi
          Issue Type: New Feature
            Reporter: Mark Payne


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.
