DocumentDB, a distinct MongoDB-compatible engine
Originally created by Microsoft, now a Linux Foundation project. Its own MongoDB-compatible gateway runs on PostgreSQL-based document storage.
FAQ
Common DocumentDB questions
Is hosted DocumentDB available on the Free plan?
DocumentDB is available on Solo and higher plans. It is not part of the Free plan.
Is this Amazon DocumentDB?
No. This is the open-source DocumentDB project originally created by Microsoft. Amazon DocumentDB is a separate AWS service.
How is this different from FerretDB?
Standalone DocumentDB uses its own gateway. FerretDB is an independent project whose 2.x versions use the DocumentDB PostgreSQL extension with their own protocol interface. Neither product is the MongoDB server itself.
Does compatibility mean every MongoDB feature works?
No. Test your queries, indexes, transactions and application against the specific engine and version before moving production data.
