Bigdata® is a horizontally-scaled, general purpose storage and computing fabric for ordered data (B+Trees), designed to operate on either a single server or a cluster of commodity hardware. Bigdata® uses dynamically partitioned key-range shards in order to remove any realistic scaling limits - in principle, bigdata® may be deployed on 10s, 100s, or even thousands of machines and new capacity may be added incrementally without requiring the full reload of all data. The bigdata® RDF database supports RDFS and OWL Lite reasoning, high-level query (SPARQL 1.1), and datum level provenance. Bigdata supports SPARQL 1.1 (including property paths), SPARQL 1.1 UPDATE, SPARQL 1.1 Basic Federated Query, and SPARQL 1.1 Service Description.
