GRAIL: Scalable Reachability Index for Large Graphs
Summary: GRAIL uses randomized interval labeling to build a scalable reachability index for massive directed graphs. Linear indexing time/space; query time ranges from constant to linear, enabling reachability on graphs with millions of nodes/edges where prior methods fail to scale.
