Quick Start

Rust

use overdrive::OverdriveDb;
use serde_json::json;

let mut odb = OverdriveDb::open("app.odb").unwrap();
odb.create_table("users").unwrap();
let id = odb.insert("users", &json!({"name":"Alice","age":30})).unwrap();
let doc = odb.get("users", &id).unwrap().unwrap();
println!("{}", doc["name"]);  // "Alice"
odb.close().ok();

Node.js

const { OverdriveDb } = require('overdrive-db');

const odb = OverdriveDb.open('app.odb');
odb.createTable('users');
const id  = odb.insert('users', { name: 'Alice', age: 30 });
const doc = odb.get('users', id);
console.log(doc.name);  // "Alice"
odb.close();

Go

import overdrive "github.com/ALL-FOR-ONE-TECH/overdrive-db-go"

odb, _ := overdrive.Open("app.odb")
defer odb.Close()
odb.CreateTable("users")
id, _ := odb.Insert("users", map[string]any{"name": "Alice", "age": 30})
doc, _ := odb.Get("users", id)
fmt.Println(doc["name"])  // Alice

Java

try (OverdriveDb odb = OverdriveDb.open("app.odb")) {
    odb.createTable("users");
    String id = odb.insert("users", Map.of("name","Alice","age",30));
    Map<String,Object> doc = odb.get("users", id);
    System.out.println(doc.get("name"));  // Alice
}

Python

from overdrive import OverdriveDb

with OverdriveDb.open("app.odb") as odb:
    odb.create_table("users")
    id = odb.insert("users", {"name": "Alice", "age": 30})
    doc = odb.get("users", id)
    print(doc["name"])  # Alice

Native Binary Distribution

The native library lives in lib/{os}-{arch}/:

lib/
  windows-x64/  overdrive.dll       (3.4MB)
  linux-x64/    liboverdrive.so
  linux-arm64/  liboverdrive.so
  macos-x64/    liboverdrive.dylib
  macos-arm64/  liboverdrive.dylib

Override path: Set OVERDRIVE_LIB_PATH env var to load a custom native lib.

Rebuild from source:

# Windows
.\scripts\build-native.ps1

# Linux / macOS
./scripts/build-native.sh
