SPARQL in the cloud using Rya

作者：

Highlights：

• 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.
