Scalable graph analytics using xGT

The Trovares xGT application is a property graph engine designed to support extremely large in-memory graphs. Our analytics tool provides large graph search capabilities for data scientists and business analysts. With rapid ingest rates and the ability to execute complex queries driven by Python scripts, xGT provides unprecedented performance and scalability, especially when processing very large data.
