DocumentDB
DocumentDB is an MIT-licensed, open-source document database built on PostgreSQL for MongoDB compatibility. It stores native BSON documents, supports document CRUD and PostgreSQL SQL operations, and offers single-field, multi-key, compound, text and geospatial indexes, including nested fields. Pgvector powers vector search for embeddings and similarity search. 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. Its gateway supports SCRAM-SHA-256 authentication, with TLS terminating at default port 10260. Hosted packages currently cover Ubuntu 24.04 and EL9 with PostgreSQL 17 or 18 for amd64 and arm64. A Kubernetes operator for failover, replication, backups and TLS is in preview and requires Kubernetes 1.35+ and cert-manager.
