> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> 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.
