The recent competition among leading NoSQL database vendors—DataStax, MongoDB, and Couchbase—has been highlighted by a series of benchmarks released over the past month. Each vendor's benchmark attempts to showcase their database's performance under specific configurations, but concerns have been raised about the transparency and accuracy of these tests. For instance, Couchbase's performance was potentially misrepresented due to cache misconfiguration, outdated client libraries, and unclear replication settings, while DataStax's Cassandra was criticized for disabling replication, impacting durability and write performance. Additionally, MongoDB's performance may not have been adequately represented due to the use of a release candidate and partitioning issues. The emphasis is on the need for transparent, real-world benchmarks that clearly communicate configurations to allow for reproducibility and fair comparison among the databases.
