Gravitino

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 aims to provide several key features:

• SSOT (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.
