# Apache Gravitino™ [![GitHub Actions Build](https://github.com/apache/gravitino/actions/workflows/build.yml/badge.svg)](https://github.com/apache/gravitino/actions/workflows/build.yml) [![GitHub Actions Integration Test](https://github.com/apache/gravitino/actions/workflows/integration-test.yml/badge.svg)](https://github.com/apache/gravitino/actions/workflows/integration-test.yml) [![License](https://img.shields.io/github/license/apache/gravitino)](https://github.com/apache/gravitino/blob/main/LICENSE) [![Contributors](https://img.shields.io/github/contributors/apache/gravitino)](https://github.com/apache/gravitino/graphs/contributors) [![Release](https://img.shields.io/github/v/release/apache/gravitino)](https://github.com/apache/gravitino/releases) [![Open Issues](https://img.shields.io/github/issues-raw/apache/gravitino)](https://github.com/apache/gravitino/issues) [![Last Committed](https://img.shields.io/github/last-commit/apache/gravitino)](https://github.com/apache/gravitino/commits/main/) [![OpenSSF Best Practices](https://www.bestpractices.dev/projects/8358/badge)](https://www.bestpractices.dev/projects/8358) ## Introduction Apache Gravitino is a high-performance, geo-distributed, and federated metadata lake. It manages metadata directly in different sources, types, and regions, providing users with unified metadata access for data and AI assets. ![Gravitino Architecture](docs/assets/gravitino-architecture.png) ## 🚀 Key Features - **Unified Metadata Management**: Manage diverse metadata sources through a single model and API (e.g., Hive, MySQL, MariaDB, HDFS, S3). - **End-to-End Data Governance**: Features like access control, auditing, and discovery across all metadata assets. - **Direct Metadata Integration**: Changes in underlying systems are immediately reflected via Gravitino’s connectors. - **Geo-Distribution Support**: Share metadata across regions and clouds to support global architectures. - **Multi-Engine Compatibility**: Seamlessly integrates with query engines without modifying SQL dialects. - **AI Asset Management (WIP)**: Support for AI model and feature tracking. ## 🌐 Common Use Cases - Federated metadata discovery across data lakes and data warehouses - Multi-region metadata synchronization for hybrid or multi-cloud setups - Data and AI asset governance with unified audit and access control - Plug-and-play access for engines like Trino or Spark - Support for evolving metadata standards, including AI model lineage ## 📚 Documentation The latest Gravitino documentation is available at [gravitino.apache.org/docs/latest](https://gravitino.apache.org/docs/latest/). This README provides a basic overview; visit the site for full installation, configuration, and development documentation. ## 🧪 Quick Start ### Use Gravitino Playground (Recommended) Gravitino provides a Docker Compose–based playground for a full-stack experience. Clone or download the [Gravitino Playground repository](https://github.com/apache/gravitino-playground) and follow its [README](https://github.com/apache/gravitino-playground/blob/main/README.md). ### Run Gravitino Locally 1. [Download](https://gravitino.apache.org/downloads) and extract a binary release. 2. Edit `conf/gravitino.conf` to configure settings. 3. Start the server: ```bash ./bin/gravitino.sh start ``` 4. To stop: ```bash ./bin/gravitino.sh stop ``` 5. (Optional) Choose UI version - By default, Gravitino uses the Web V2 UI. - To switch back to the legacy v1 UI at runtime, edit `conf/gravitino-env.sh` (or set the environment variable before starting) and set `GRAVITINO_USE_WEB_V2` to `false`: ```bash export GRAVITINO_USE_WEB_V2=false ./bin/gravitino.sh restart ``` - To use Web V2 explicitly, set `GRAVITINO_USE_WEB_V2=true`. ## 🧊 Iceberg REST Catalog Gravitino provides a native Iceberg REST catalog service. See: [Iceberg REST catalog service](https://gravitino.apache.org/docs/latest/iceberg-rest-service/) ## 🗄️ Lance REST Catalog Gravitino provides a native Lance REST catalog service. See: [Lance REST catalog service](https://gravitino.apache.org/docs/latest/lance-rest-service/) ## 🔌 Trino Integration Gravitino includes a Trino connector for federated metadata access. See: [Using Trino with Gravitino](https://gravitino.apache.org/docs/latest/trino-connector/index/) ## 🛠️ Building from Source Gravitino uses Gradle. Windows is not currently supported. Clean build without tests: ```bash ./gradlew clean build -x test ``` Build a distribution: ```bash ./gradlew compileDistribution -x test ``` Skip building and packaging both Web UIs: ```bash ./gradlew compileDistribution -PskipWebBuild=true -x test ``` Or compressed package: ```bash ./gradlew assembleDistribution -x test ``` Artifacts are output to the `distribution/` directory.
