This technical report compares the throughput and latency of two NoSQL databases as a service (DBaaS) across four different workloads and three cluster configurations.
NoSQL systems were created to support the demands of modern, globally distributed, cloud-native applications. While NoSQL solutions help to maximize performance and uptime for modern application workloads, database-as-a-service alternatives may assist in saving time and money on cluster support, deployment, and maintenance.
This study evaluates the latency and throughput of Couchbase Capella™ (March 2022 release) and MongoDB™ Atlas v5.0 under four workloads:
The comparison was conducted on three cluster configurations: 6, 9, and 18 nodes. For consistency, the Yahoo! Cloud Serving Benchmark was utilized. The performance results are supported by seven descriptive tables and four comparative diagrams.
