Class SailFederationEvalStrategy

All Implemented Interfaces:
EvaluationStrategy, FederatedServiceResolver, FederatedServiceResolverClient, UUIDable

public class SailFederationEvalStrategy extends FederationEvalStrategy
Implementation of a federation evaluation strategy which provides some special optimizations for Native (local) RDF4J repositories. The most important optimization is to use prepared Queries that are already created in the internal representation used by RDF4J. This is necessary to avoid String parsing overhead. Joins are executed using ControlledWorkerJoin
