🚀 Quick Start

Installation

uv pip install arcadedb-embedded

Requirements:

• Python 3.10–3.14 (packaged/tested on CPython 3.12) - No Java installation required!
• Supported Platforms: Prebuilt wheels for 4 platforms
  • Linux: x86_64, ARM64
  • macOS: Apple Silicon (ARM64)
  • Windows: x86_64

5-Minute Example

import arcadedb_embedded as arcadedb

# Create database (context manager for automatic open and close)
with arcadedb.create_database("./mydb") as db:
    # Create schema (DDL)
    db.command("sql", "CREATE DOCUMENT TYPE Person")
    db.command("sql", "CREATE PROPERTY Person.name STRING")
    db.command("sql", "CREATE PROPERTY Person.age INTEGER")

    # Insert data (requires transaction)
    with db.transaction():
        db.command("sql", "INSERT INTO Person SET name = 'Alice', age = 30")

    # Query data
    result = db.query("sql", "SELECT FROM Person WHERE age > 25")
    for record in result:
        print(f"Name: {record.get('name')}")

📦 What's Inside

The arcadedb-embedded package is platform-specific and self-contained:

Package Contents (current Linux x86_64 dev build; varies by platform and version):

• Wheel size (compressed): ~73MB
• ArcadeDB JARs (uncompressed): ~32MB
• Bundled JRE (uncompressed): ~60MB (platform-specific Java 25 runtime via jlink)
• Installed package size: ~102MB

The compressed wheel size is measured from dist/*.whl, and the installed package size is measured from the extracted site-packages/arcadedb_embedded/ directory.

Note: Some JARs are excluded to optimize package size (e.g., gRPC wire protocol). See jar_exclusions.txt for details.

Import: import arcadedb_embedded as arcadedb

🧪 Testing

Status: 277 passed across 27 test files

# Run all tests

# Run specific test file
pytest tests/test_core.py -v

See testing documentation for detailed test documentation.

🔧 Building from Source (Advanced)

Linux uses Docker. macOS and Windows use a native Java 25+ JDK with jlink.

cd bindings/python/

# Install uv (one-time)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Create virtual environment with uv
uv venv .venv
source .venv/bin/activate

# Install build and test dependencies
uv pip install build
uv pip install -e ".[test]"

# Build for your current platform (auto-detected)
./build.sh

Built wheels will be in dist/.

Build instructions

Developer Note: See build architecture docs for comprehensive documentation of the multi-platform build architecture, including how we achieve platform-specific JRE bundling across the supported platforms on GitHub Actions.

Development

Versions are automatically extracted from the main ArcadeDB pom.xml. See versioning strategy for details on development vs release mode handling.
