The Linux Foundation has welcomed DocumentDB, an open source NoSQL database built on PostgreSQL, as its latest project. Announced on August 25, 2025, at the Open Source Summit Europe in Amsterdam, this move aims to create a new open standard for NoSQL databases under the permissive MIT license, backed by major players like Microsoft, AWS, and Google.
This adoption comes as developers seek alternatives to restrictive licenses in the NoSQL space. It highlights a shift toward more open, flexible options that blend NoSQL speed with PostgreSQL reliability.
Background on DocumentDB and Its Roots
DocumentDB started as a Microsoft project in 2024. The company built it as extensions to PostgreSQL, adding support for BSON data models and MongoDB-compatible operations.
Microsoft released it openly in January 2025, stressing its MIT license as a key feature. This allows free use, modification, and distribution without forcing users to share changes back.
The project gained quick traction. By mid-2025, it had nearly 2,000 GitHub stars and hundreds of contributions. Developers praised its ease of use and integration with existing PostgreSQL tools.
This rapid growth led to the Linux Foundation partnership. The foundation sees DocumentDB as a way to push developer-first innovation in NoSQL.
Key Features of DocumentDB
DocumentDB combines NoSQL flexibility with PostgreSQL strengths. It handles document-oriented data while keeping ACID guarantees.
Users can run MongoDB workloads on it without major changes. This makes migration simple for teams moving from other NoSQL systems.
Here are some standout features:
- Full MongoDB API compatibility for easy adoption.
- Built on PostgreSQL for strong reliability and ecosystem support.
- Permissive MIT license that encourages broad use and forking.
- Cloud-agnostic design, working across providers like Azure, AWS, and Google Cloud.
Performance tests show it handles high-throughput tasks well. Early adopters report faster queries compared to some traditional NoSQL setups.
One user on social media noted its seamless integration with existing Postgres clusters. This reduces the need for separate databases in mixed environments.
Why the Shift to Linux Foundation Matters
The move responds to frustrations with licenses like MongoDB’s SSPL. That license requires cloud providers to share service code, which many resist.
In contrast, MIT offers freedom without such demands. This has drawn support from big tech firms eager for open standards.
Microsoft developed DocumentDB to fill this gap. It provides NoSQL capabilities on a trusted relational base.
The Linux Foundation will now oversee governance. This ensures neutral development and wider community input.
Experts say this could standardize NoSQL queries, much like SQL did for relational databases. It might reduce vendor lock-in and boost interoperability.
Recent events, like Redis switching from SSPL to AGPL, show a trend toward permissive options. DocumentDB fits this pattern, offering a middle ground with strong backing.
Community Reactions and Adoption Trends
Reactions have been positive across tech communities. Developers on platforms like X and Reddit highlight the MIT license as a game-changer.
One post called it a win for open source, predicting quick uptake by startups and enterprises. Another praised the PostgreSQL foundation for adding NoSQL without losing reliability.
Adoption is growing fast. Companies are testing it for scalable apps, from e-commerce to real-time analytics.
| Aspect | DocumentDB | Traditional NoSQL (e.g., MongoDB) |
|---|---|---|
| License | MIT (permissive, no share-back required) | SSPL (requires code sharing for services) |
| Base System | PostgreSQL (relational with ACID) | Standalone NoSQL (flexible but less ACID focus) |
| Compatibility | MongoDB API | Native MongoDB |
| Community Backing | Linux Foundation, Microsoft, AWS, Google | MongoDB Inc. and community |
| Use Case Strength | Hybrid SQL/NoSQL workloads | Pure document storage |
This table shows how DocumentDB stands out. It appeals to those wanting openness without complexity.
Some worry about fragmentation in the NoSQL space. But supporters argue it promotes healthy competition.
Future Outlook for Open NoSQL
Looking ahead, DocumentDB could reshape NoSQL development. With Linux Foundation support, expect more features like advanced sharding and AI integrations.
By 2026, analysts predict wider use in cloud-native apps. This ties into trends like serverless computing and multi-cloud strategies.
Microsoft plans ongoing contributions. Other firms may join, expanding the ecosystem.
This adoption signals a broader push for open standards. It solves real problems for developers facing license hurdles.
