Blazegraph

Blazegraph is a high-performance graph database optimized for RDF/SPARQL and Blueprints APIs, capable of scaling to 50 billion triples on a single machine.

Blazegraph (formerly Bigdata) provides a robust, ultra-scalable platform for graph-based applications. It supports the W3C SPARQL 1.1 standard and offers a high-concurrency architecture that powers mission-critical deployments like the Wikidata Query Service. The platform features an N-Way High Availability (HA) mode for consistent performance and a GPU-accelerated analytics engine (Blazegraph DASL) that executes complex graph traversals up to 100x faster than traditional CPU-based methods. Its ability to handle massive datasets with low latency makes it a primary choice for enterprise knowledge graphs and linked data projects.
