SPARQL in the cloud using Rya
We build a scalable RDF data management system in a cloud environment. Rya is based on Accumulo columnar store and OpenRDF Sesame framework. We used 3 indexed tables, SPO, POS, OSP, with triple data stored in the row ID. We implemented performance enhancements to scale to billions of triples and milliseconds query time for most queries. Rya provides fast and easy access to the data through SPARQL.
