Comparison of Distributed "No-SQL" Databases with an Emphasis on Performance and Scalability

Abstract

This thesis deals with NoSQL database performance issue. The aim of the paper is to compare most common prototypes of distributed database systems with emphasis on performance and scalability. Yahoo! Cloud Serving Benchmark (YCSB) is used to accomplish the aforementioned aim. The YCSB tool allows performance testing through performance indicators like throughput or response time. It is followed by a thorough explanation of how to work with this tool, which gives readers an opportunity to test performance or do a performance comparison of other distributed database systems than of those described in this thesis. It also helps readers to be able to create testing environment and apply the testing method which has been listed in this thesis should they need it. This paper can be used as a help when making an arduous choice for a specific system from a wide variety of NoSQL database systems for intended solution
