Package providing management for federation of datastores. This allows us to have a PMF/EMF for multiple datastores, and to distribute any insert/update/delete/fetch to the relevant datastore. It also allows us to query across multiple datastores and federate the results.
The more standard alternative to this is to have a PMF per datastore, and then to persist to whichever you want, and query whichever you want. Merging results is then left to the user.
