Performance Evaluation of NoSQL Document Databases: Couchbase, CouchDB, and MongoDB

NoSQL document databases emerged as an alternative to relational for managing large volumes of data. ensure big data storage and good query performance are essential when the scheme does not fit into databases. They store their in form documents can handle unstructured, semi-structured, structured This work evaluates top three open-source databases: Couchbase, CouchDB, MongoDB with Yahoo! Cloud Serving Benchmark (YCSB), which has become a standard database evaluation. The scale-up assessed using YCSB workloads different number records threads, where runtime is measured each database. In experimental evaluation, we concluded that best runtime, except workload composed by scan operations. addition, identified CouchDB varying threads.
