GraphX Pregel API
Graph data and graph processing is getting more and more attention lately in various fields. It has become apparent that a large number of real world problems can be described in terms of graphs, for instance, the Web graph, the social network graph, the train network graph and the language graph. Often these graphs are exceptionally huge, take the Web graph for example, it is estimated that the number of web pages may have exceeded 30 billion. We are in need of a system that is able to process these graphs created by modern applications.
