Couchbase Capella has been found to surpass MongoDB Atlas, Redis Enterprise Cloud, and Amazon DynamoDB in terms of features, performance, and total cost of ownership (TCO) across diverse workloads and cluster sizes. This is demonstrated through a benchmark study commissioned by Couchbase, which utilized the widely accepted YCSB standard for benchmarking NoSQL databases. The study evaluated four DBaaS solutions: Couchbase Capella, MongoDB Atlas, Redis Enterprise Cloud, and Amazon DynamoDB, using various workload tests such as workloads A, C, E, and pagination. The results show that Couchbase Capella excels in performance, functionality, and TCO, particularly in update-heavy use cases and scenarios involving caching, pagination, and high throughput.
