The Bigdata® RDF Graph Database

ByBryan Thompson, Mike Personick, Martyn Cutcher

Bigdata is a standards-based, high-performance, scalable, open-source graph database. Written entirely in Java, the platform supports the SPARQL 1.1 family of specifications, including Query, Update, Basic Federated Query, and Service Description. Bigdata supports novel extensions for durable named solution sets, efficient storage and querying of reified statement models1, and scalable aggregation operations on graphs. The database supports multitenancy and can be deployed as an embedded database, a standalone server, a highly available replication cluster, and as a horizontally-sharded federation of services similar to Google’s BigTable [132], Apache Accumulo [35], or Cassandra [36,351].
