I/O Characteristics of NoSQL Databases

The advent of the so-called NoSQL databases has brought about a new model of using storage systems. While traditional relational database systems took advantage of features offered by centrally-managed, enterprise-class storage arrays, the new generation of database systems with weaker data consistency models is content with using and managing locally attached individual storage devices and providing data reliability and availability through high-level software features and protocols. This paper aims to review the architecture of several existing NoSQL DBs with an emphasis on how they organize and access data in the shared-nothing locally-attached storage model.
