Apache Rya is a Big Data triple store that provides scalable storage, retrieval, and analysis of RDF dataGet Rya
Rya (pronounced “ree-uh” /rēə/) is a cloud-based RDF triple store that supports SPARQL queries. Rya is a scalable RDF data management system built on top of Apache Accumulo®. A MongoDB back-end is also implemented. Rya uses novel storage methods, indexing schemes, and query processing techniques that scale to billions of triples across multiple nodes. Rya provides fast and easy access to the data through SPARQL, a conventional query mechanism for RDF data.
