Apache Spark GraphX

GraphX is Apache Spark's API for graphs and graph-parallel computation. GraphX unifies ETL, exploratory analysis, and iterative graph computation within a single system. You can view the same data as both graphs and collections, transform and join graphs with RDDs efficiently, and write custom iterative graph algorithms using the Pregel API. GraphX competes on performance with the fastest graph systems while retaining Spark's flexibility, fault tolerance, and ease of use.
