Azure Cosmos DB
Fully managed, globally distributed NoSQL database service offering multi-model support with low-latency access worldwide
PoloDB
Rust‑powered embedded NoSQL database with MongoDB‑style API
PoloDB is a lightweight, cross‑platform Rust library offering an embedded document store with a MongoDB‑compatible API, supporting multi‑threading, multi‑sessions, and optional standalone server mode.
Overview
Overview
PoloDB provides Rust developers with a compact, document‑oriented database that can be linked directly into an application or run as a standalone server. Its API mirrors MongoDB’s query language, making it easy to adopt for teams familiar with NoSQL patterns while retaining the low‑overhead, single‑file storage model of embedded databases.
Who it’s for and how to deploy
Ideal for desktop, CLI, or server‑side tools that need fast, concurrent access to JSON‑like data without the complexity of a remote database. Include polodb_core in a Rust binary to open a local file, or launch the polodb executable to expose the MongoDB wire protocol for external clients. The library runs on any platform supported by the Rust compiler, with confirmed builds on macOS, Linux, and Windows.
Highlights
MongoDB‑like API for familiar query syntax
Embeddable library and optional standalone server
Multi‑threading and multi‑session support
Cross‑platform Rust implementation
Pros
- Lightweight footprint suitable for client‑side storage
- Familiar MongoDB query language reduces learning curve
- Native Rust safety and performance
- Flexible deployment: embedded or server mode
Considerations
- Smaller ecosystem and tooling compared to SQLite
- Limited platform testing (macOS, Linux, Windows only)
- Early‑stage project; some advanced features still pending
- No official language bindings beyond Rust yet

Fit guide
Great for
- Rust applications needing local document storage
- Projects preferring NoSQL over relational for client‑side data
- Multi‑threaded services requiring concurrent sessions
- Developers wanting MongoDB‑style API without an external server
Not ideal when
- Environments that require the maturity of SQLite
- Mobile platforms such as iOS and Android (not yet supported)
- Applications needing extensive language bindings
- Use cases demanding advanced DB features not yet implemented

Frequently asked questions
Is PoloDB compatible with existing MongoDB drivers?
The standalone server implements MongoDB's wire protocol, so many drivers work, though some advanced features may be missing.
Can I use PoloDB as an embedded library in a Rust binary?
Yes, import `polodb_core` and open a database file directly from your Rust application.
What platforms are officially supported?
It has been compiled and tested on macOS Big Sur x64, Linux x64 (Fedora 32), and Windows 10 x64.
Does PoloDB support transactions?
Basic transaction support is implemented and available for use.
Is there a roadmap for language bindings?
Bindings for Python and JavaScript are planned but have not been released yet.
