GraphFlow: Workflow-based big graph processing

We introduce GraphFlow, a big graph framework that is able to encode complex data science experiments as a set of high-level workflows. GraphFlow combines the Spark big data processing platform and the Galaxy workflow management system to offer a set of components for graph processing using a novel interaction model for creating and using complex workflows. GraphFlow contributes an easy-to-use interface and scalable algorithms for big graph analytics. We demonstrate GraphFlow use in large social network analysis with several case studies.
