Open-source DocumentDB 1.0 hits GA, letting you run MongoDB-style queries on PostgreSQL

DocumentDB 1.0, an open-source document database from Microsoft and the Linux Foundation, has officially launched. It's built as a PostgreSQL extension and gateway that translates the MongoDB wire protocol, allowing most MongoDB drivers and queries to work without changes. The project, backed by major players like AWS, Google, and Snowflake, aims to provide a fully visible, MIT-licensed alternative to proprietary NoSQL options.

For engineers, this means a new deployment choice that leverages PostgreSQL's robustness while maintaining familiarity with the MongoDB API. It offers commercial flexibility without the licensing restrictions of MongoDB's SSPL. The release focuses on security, stability, and improved support for indexing and geospatial queries. The main takeaway is a significant, vendor-neutral option for document storage that could reshape infrastructure decisions.
