Interoperability

Multimodal interface provides interoperability across lakehouse formats like Delta Lake, Apache IcebergTM, major cloud platforms, and various compute engines.

Openness

Open APIs and open source server offer maximum flexibility and customer choice by ensuring broad interoperability.

Unified Governance for data and AI

Built-in governance and security for tabular, non-tabular data as well as AI assets such as Gen AI tools

Interoperability across any format and engine

Unity Catalog supports Delta Lake, Apache IcebergTM via UniForm, Parquet, CSV, JSON, and many other formats. It also implements the Iceberg REST Catalog APIs to interoperate with a broad ecosystem.

Openness

Unity Catalog is Apache 2.0 licensed, including an OpenAPI specification, server and clients. Adoption of open standards maximizes flexibility and customer choice by ensuring extensive interoperability across various engines, tools, and platforms.

Multi-format support (Delta, Iceberg and Hudi as UniForm)
Beyond tables - Unstructured data (Volumes) and AI assets (ML models, Gen AI tools)
Plugin support - extensible to Iceberg REST Catalog and HMS interface for client compatibility, plus additional plugins (e.g., integration with a new AI framework)
Delta Sharing open protocol for sharing tabular and non-tabular assets cross-domain

Unified governance for data and AI

Unity Catalog has built-in governance and security – with strong authentication, secure credential vending, and asset-level access control to protect your data and AI assets with a unified solution. Manage unstructured data, such as images and documents, and Gen AI tools with a single, universal catalog.
