One of the main open issues is how to effectively partition a large graph to process complex graph operations efficiently. In this paper, we present a distributed data partitioning framework for efficient processing of large-scale graphs in the Cloud. First, we introduce extended vertex blocks as graph partitioning building blocks. Second, we propose vertex block grouping algorithms which group those vertex blocks that have high correlation in graph structure to the same partition. Third, we propose a partition-guided query partitioning model which transforms graph queries into vertex block-based graph query patterns for parallel processing of graph queries. We conduct extensive experiments on several real-world graphs to show the effectiveness and scalability of our framework.
