Transaction management for cloud-based graph databases

Abstract

Many graph databases, both open and proprietary, have been recently developed to efficiently store and manage graph structured data. As the volume of such data grows, graph databases most often offer distributed solutions implemented in a cloud infrastructure. In this paper, we focus on transaction management for such cloud-based graph databases. In particular, we use various graph databases as case studies to survey the different levels of transaction support and concurrency control protocols offered. We also study data distribution issues and replication protocols. Finally, we highlight open issues that need to be addressed in the future.
