Nosql Comparative Performance Study

This article aims to introduce the concept of NoSQL, describe the database systems Cassandra and MongoDB, but above all, perform a comparative study (practical) of both systems, on the same dataset. The YCSB benchmark tool is to test different types of operations - reading, writing, and reading and writing - by performing these tests on various workloads, through progressive increases of clients to perform the operations, in order to compare the two solutions in terms of performance. Preliminary results show that Cassandra generally performs better in all types of operations, but it depends more on the capacity in terms of resources of the machine. On the other hand, MongoDB is able to achieve better results in a scenario where hardware resources are lower, with performance levels slightly higher than Cassandra.
