Lusail: A System for Querying Linked Data at Scale

Summary: Lusail: scalable federated SPARQL for geo-distributed RDF graphs. Instance-aware query rewriting pushes computation to local endpoints, exposes parallelism, and enables runtime scheduling to boost scalability; demonstrates orders-of-magnitude speedups over state-of-the-art systems.
