Frequently Asked Questions

What is a managed NoSQL database?

A NoSQL database run by a cloud provider or vendor, which handles provisioning, scaling, backups and patching.

How do I choose between NoSQL types?

Use document stores for flexible JSON, key-value for caching and simple lookups, wide-column for massive write-heavy workloads, and graph for relationship queries.

Which are the most-used services?

DynamoDB, Cosmos DB, Firestore and Bigtable from the hyperscalers, and MongoDB Atlas and Couchbase Capella across clouds.

What replaced the older entries?
