Graphs are a powerful, flexible means of representing all kinds of linked data. Bigdata is an ultra high-performance graph database supporting the RDF data model, which provides a standards-based way of describing, interchanging, and querying graph data. Bigdata supports both the Sesame and Blueprints APIs.
Bigdata handles very Big Graphs. Bigdata scales to 50 billion edges on a single machine and will scale to even larger graphs with its horizontally-scaled architecture. Bigdata supports robust enterprise deployments with high up-time and QoS demands with its quorum-based high-availability (HA) architecture.
Bigdata is 100% open-source.
