Hi Orlin, Jena is not a triple store, but a middleware API. Ok, it does have some triple stores (SDB and TDB) included, but SPIN only relies on the Model and Graph APIs which can sit on top of any physical storage layer. For example, you can run the SPIN API on top of Oracle via the Oracle Jena adapter (performance may not be optimal in this case, compared to TDB of course). In the case of the Oracle adapter, SPIN would load the triples it needs to run specific rules and constraints, but leave the bulk of the data on the server.
I would be interested in hearing more about your planned use case, so that I can give a better qualified response. You can take this off- list if you prefer.
