DocumentDB
What it is
DocumentDB is an MIT-licensed, open-source document database built on PostgreSQL with MongoDB compatibility. It stores native BSON documents while supporting document CRUD and PostgreSQL SQL operations. Indexes include single-field, multi-key, compound, text, and geospatial types, including nested fields. Vector search for embeddings and similarity search uses pgvector. MongoDB-compatible clients and tools include mongosh, PyMongo, the official MongoDB Node.js driver, and a VS Code extension. The extension can create a local database, generate credentials, and save a connection. DocumentDB runs locally in Docker or on a user’s infrastructure or cloud, with SCRAM-SHA-256 authentication and TLS terminating at the gateway, whose default port is 10260. Current hosted packages cover Ubuntu 24.04 and EL9 with PostgreSQL 17 or 18 for amd64 and arm64. Packages are not available for Ubuntu 22.04, Debian 11–13, EL8, or PostgreSQL 16. A Kubernetes operator offering failover, replication, backups, and TLS is marked preview.
For and against
For
- MIT-licensed open-source database
- MongoDB-compatible clients and drivers
- BSON documents with PostgreSQL SQL
- Multiple index types and vector search
- Docker, self-hosted, and cloud deployment
Against
- Hosted packages support limited OS and PostgreSQL versions
- Kubernetes operator is preview software
- TLS terminates at the gateway
- No hosted packages for PostgreSQL 16
The verdict
DocumentDB combines MongoDB-style documents and tooling with PostgreSQL operations, indexing, and pgvector search. Check the supported package matrix and preview status before choosing a deployment path.
Who it suits
It suits developers needing MongoDB-compatible document storage alongside PostgreSQL SQL capabilities. Teams can run it locally, on their own infrastructure, or in cloud environments.
