Introduction

Gravitino is a high-performance, geo-distributed, and federated metadata lake. It manages the metadata directly in different sources, types, and regions. It also provides users with unified metadata access for data and AI assets.

Gravitino Architecture

Gravitino aims to provide several key features:

  • Single Source of Truth for multi-regional data with geo-distributed architecture support.
  • Unified Data and AI asset management for both users and engines.
  • Security in one place, centralizing the security for different sources.
  • Built-in data management and data access management.

You can find the latest Gravitino documentation in the doc folder. This README file only contains basic setup instructions.

Building Gravitino

You can build Gravitino using Gradle. Currently you can build Gravitino on Linux and macOS, Windows isn't supported.

To build Gravitino, please run:

./gradlew clean build -x test

If you want to build a distribution package, please run:

./gradlew compileDistribution -x test

to build a distribution package.

Or:

./gradlew assembleDistribution -x test

to build a compressed distribution package.

The directory distribution contains the generated binary distribution package.

For the details of building and testing Gravitino, please see How to build Gravitino.

Quick start

Configure and start the Gravitino server

If you already have a binary distribution package, go to the directory of the decompressed package.

Before starting the Gravitino server, please configure the Gravitino server configuration file. The configuration file, gravitino.conf, is in the conf directory and follows the standard property file format. You can modify the configuration within this file.

To start the Gravitino server, please run:

./bin/gravitino.sh start

To stop the Gravitino server, please run:

./bin/gravitino.sh stop

Using Trino with Gravitino
