Apache Giraph: Graph Processing for Hadoop V2

Apache Giraph is a graph processing tool for Hadoop V2 that offers better performance for tasks that don't fit MapReduce. It operates through iterations called super steps using Bulk Synchronous Parallel computing (BSP). Licensed via Apache, it's ideal for distributed computing and massive calculations.
