TippyDB: Geographically-aware distributed NoSQL Key-Value store

The need of scalable databases has raised rapidly in these past few years. Researchers and developers have tried to develop several techniques to create replications and partitions in non-relational databases. However, high latency between distributed data centers has imposed a costly bottleneck to the system's performance. In this paper, we present a system design for nonrelational database — TippyDB — that provides better response time for users who are accessing our service. We enhance our system with the important observation that interactions between people almost always happen in a limited geographical area. We demonstrate that, in contrast with other NoSQL databases, our system offers a considerable improvement of performance in a distributed environment.
