Gravitino

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 aims to provide several key features:

• Unified Metadata Management: Gravitino provides a unified model and API to manage different types of metadata, including relational (e.g., Hive, MySQL) and file-based (e.g., HDFS, S3) metadata sources.

• End-to-End Data Governance: Gravitino offers a unified governance layer for managing metadata with features like access control, auditing, and discovery.

• Direct Metadata Management: Gravitino connects directly to metadata sources via connectors, ensuring changes are instantly reflected between Gravitino and the underlying systems.

• Geo-Distribution Support: Gravitino enables deployment across multiple regions or clouds, allowing instances to share metadata for a global cross-region view.

• Multi-Engine Support: Gravitino supports query engines enabling metadata access without modifying SQL dialects.

• AI Asset Management (WIP): Gravitino is expanding to manage both data and AI assets, with support for AI models and features currently in development.
