H2 RDF+: An Efficient Data Management System for Big RDF Graphs
Summary: H2RDF+ is an RDF store for large graphs, using distributed Merge and Sort-Merge joins over a multi-index scheme on HBase. A greedy cost-model planner toggles single- vs multi-machine execution for complex joins, with a web GUI for real-time monitoring and comparisons to two RDF stores.
