I. Introduction
As one of the largest social media globally, Twitter manipulates multiple large-scale graphs with billions of vertices and edges. Implementing graph analytics on such large-scale graphs has been a long-lasting pain. Moreover, we have witnessed a growing need for large-scale graph analytics at Twitter in recent years. For example, recommendation teams are running PageRank and topic similarity tasks on the user-follow graph to measure the influence of Twitter users. Health teams are running multi-account detection on the safety graph to detect any or all Twitter accounts owned by the same person and combined connected users jobs to build relationships between users.
