Performance Evaluation of NoSQL Systems using YCSB in a Resource Austere Environment
International Journal of Applied Information Systems, 2014 NoSQL is a database used to store high volume of data. NoSQL databases are horizontally scalable, distributed, open source and non-relational. High performance is a major concern for practically every data-driven system. NoSQL databases claim to deliver faster performance than the popular Relational database systems in various use cases, most notably ...
