GoldenOrb is a cloud-based open source project for massive-scale graph analysis, built upon best-of-breed software from the Apache Hadoop project modeled after Google’s Pregel architecture. Our goal is to foster solutions to complex data problems, remove limits to innovation and contribute to the emerging ecosystem that spans all aspects of big data analysis.
Anticipated for some time, see: Beyond MapReduce – Large Scale Graph Processing With GoldenOrb
