DocumentDB 1.0 arrives as an MIT MongoDB-wire database on Postgres

DocumentDB 1.0 is now generally available, the project team said on its own blog. The post is on documentdb.io, dated 19 October, under the byline "DocumentDB team". InfoQ reported on the release on 14 November, which is how this item reached us.

DocumentDB is an MIT-licensed document database. It speaks the MongoDB wire protocol and stores native BSON inside PostgreSQL. That is the project's own account. Most MongoDB drivers, tools and queries work against it unchanged. The data lives in a Postgres database a team can run and inspect like any other, the team says.

What is in 1.0

The release is tagged v1.0-0 and carries the same code as the second release candidate, the team says. Containers are on ghcr.io/documentdb/documentdb/documentdb-local with tags from pg15-1.0.0 through pg18-1.0.0. The latest tag points at PostgreSQL 17. Linux packages are built for Ubuntu 24.04 and EL9 on PostgreSQL 17 or 18, on amd64 or arm64.

1.0 is a stabilisation release more than a feature one. The notes list security fixes in find, aggregate, $merge, $out, createUser and updateUser. There are stability fixes in $getField, $setField, $firstN, $lastN, $documents and $facet. Geospatial operators $near, $nearSphere and $geoNear no longer fail on nearly coincident points or at longitude -180, the team says. Collation support is off by default and is opt-in through documentdb_core.enableCollation.

An upgrade path exists from v0.116 or v0.117 only. Fresh container volumes require a dump-and-restore.

Telemetry is on by default

A new detail for operators: the container image sends usage telemetry by default, through Scarf. The payload is the image version, the operating system and the CPU architecture. It is sent once at startup and then every hour. That is the team's own account. The telemetry never includes any data, query, name or credential, by the project's account. It can be turned off.

Who runs it

The project footer says "DocumentDB a Series of LF Projects, LLC", which places it under the Linux Foundation. InfoQ reports that Microsoft announced DocumentDB as open source in early 2025. The project joined the Linux Foundation a few months later, InfoQ says. The backers it names are AWS, Cockroach Labs, Google, Snowflake and Yugabyte. InfoQ is the only source for that list. The project's own blog post names none of these backers.

For a team already running against MongoDB, DocumentDB 1.0 is the first release committed to long-term support. The licence is MIT. A migration still has to be planned. The operators in these release notes are fixed one by one. A real test suite has to run against real queries before any production move. The telemetry-on-by-default choice is worth catching on day one, especially for teams locked into a data residency rule.
