Apache: Big Data North America 2017

Apache Rya (incubating) is a scalable database management system designed for storing and searching very large Resource Description Framework (RDF) data. In its most basic form, RDF data is a triple. Due to its flexibility, RDF is the current standard for storing a many different types of information. With the explosive increases in the size of available data, scalable solutions are needed to efficiently store and query very large RDF graphs within big data architectures. Apache Rya is an RDF triple store built on top of Apache Accumulo. We introduce storage methods, indexing schemes, query optimization, and query evaluation techniques that allow Rya to scale to billions of triples across multiple nodes, while providing fast and easy access to the data through conventional query mechanisms such as SPARQL.
