Introduction

PoloDB is an embedded document database written in Rust. It stores BSON documents and provides a MongoDB-like API without requiring a separate database process.

This documentation targets PoloDB v5.2.0. Changes available only on the master branch are not documented as stable features until they are included in a release.

Why

PoloDB offers a document-oriented alternative to SQLite for applications that need local, persistent data. It combines a MongoDB-like data model with an embedded, lightweight Rust API and a RocksDB storage engine.

Features

• Simple and Lightweight
• Easy to learn and use
  • NoSQL
  • MongoDB-like API
• Persistent, RocksDB-backed storage
• Embedded library and optional standalone server
• Cross-Platform

Platform

PoloDB can be built on platforms supported by the Rust and RocksDB toolchains. For the standalone server, the v5.2.0 release page (opens in a new tab) provides prebuilt x64 binaries for macOS, Linux, and Windows.
