networks may have millions of nodes (or even a few billion) with an even larger number of edges.
The nodes and edges are dynamic, and may have multiple versions. Essentially, these networks
transform into large dynamic graph structures. There is an urgent need to manage these graph
structures and analyze them to determine suspicious behavior in various individuals. Furthermore,
