Announced at AWS re:Invent 2023 in Las Vegas, the new service introduces a columnar store and data integration into the Capella Database-as-a-Service (DBaaS) for applications such as customer profiling and special offers.
Couchbase emphasized the differences in its approach. It said MongoDB created a duplicative indexing structure against the data that persists in its singular storage engine, WiredTiger. Couchbase claimed WiredTiger consumes half the available memory when in use, "which is one of the reasons that MongoDB does not scale as efficiently as Couchbase and Capella."
The in-memory analytics system is only available as a package with the main DBaaS, but offers support for Tableau and PowerBI for analytic development and visualization.
