> Currently sparql engines and triple store implementations are fully isolated by a generic
wrapper that prevents TDB-backed stores to perform sparql queries as efficiently as possible.
> Proposed solution by Reto on the developers mailing list:
> TcProvider can Implement an additional Subinterface (say SparqlTcProvider) allowing to
pass Sparql-queries to them. If a sparql query affects only graphs provided by the same SparqTcProvider
the the query is forwarded to that provider, otherwise the current process applies.
