JCC_V3_N2_RP1 Amandeep Kaur Kanwalvir Singh Dhindsa Journal on Cloud Computing 2350-1308 3 2 1 9 NoSQL, CRUD Operations, Execution Time, Throughput, MongoDB, Cassandra, Couchbase With the Web growing rapidly and increase in user-generated content websites such as Facebook and Twitter, there is a need for fast databases that can handle huge amounts of data. For this purpose, new database management systems collectively called NoSQL are being developed. There are many NoSQL database types with different performances, and thus it is important to evaluate performance. To check the performance, three major NoSQL databases called MongoDB, Cassandra, and Couchbase have been considered. For performance analysis, different workloads were designed. The evaluation has been done on the basis of read and update operations. This evaluation enables users to choose the most appropriate NoSQL database according to the particular mechanisms and application needs.
