What’s new with Databricks Unity Catalog at Data + AI Summit 2025

Four years ago, Databricks saw tremendous complexity in the data landscape: separate catalogs for each platform, siloed governance tools across clouds, and no unified way to secure AI assets. We pioneered Unified Governanceby launching Unity Catalog, an open, flexible catalog layer to manage access, lineage, auditing, and discovery across all data and AI assets.

Today, Unity Catalog has become the foundation of the Databricks Data Intelligence Platformand the industry's only unified governance solution for data and AI across formats, clouds, and engines. From open data sharing to fine-grained security and knowledge governance, Unity Catalog helps organizations bring context, control, and confidence to their data estate.

At this year's Data + AI Summit, we're announcing major innovations across Unity Catalog, delivering the best catalog for Apache Iceberg™, new business user experiences, and intelligent governance to protect sensitive data and ensure trusted data quality at scale.

Here's what's new.

The Best Catalog for Apache Iceberg™

Organizations adopting a lakehouse are often forced to choose between Delta Lake and Apache Iceberg™. That choice creates artificial silos: restricting access to the data and AI tools that teams can use, fragmenting governance, and locking metadata into format-specific catalogs.

Unity Catalog eliminates the need to choose. Built on open standards, Unity Catalog is the only unified catalog that works seamlessly across formats, engines, and clouds, making it the foundation of the open lakehouse. Over the past year, following the acquisition of Tabular,we've invested deeply in Apache Iceberg to extend this vision. We're excited to announce:

• Full support for the Iceberg REST Catalog API, allowing external engines to read (Generally Available) and write (Public Preview) to Unity Catalog-managed Iceberg tables. This is a major differentiator in the market, eliminating format lock-in and enabling full interoperability unmatched by any other solution.
• Iceberg managed tablesare now in Public Preview, delivering best-in-class price and performance, liquid clustering, predictive optimization, and full integration with Databricks and across external engines, including Trino, Snowflake, and Amazon EMR.
• Iceberg catalog federationis in Public Preview, enabling you to govern and query Iceberg tables managed in AWS Glue, Hive Metastore, and Snowflake Horizon without copying data.
• Delta Sharing for Icebergis now in Private Preview, allowing you to share Unity Catalog tables and Delta tables with any recipient using Delta Sharing and consume them in any client that supports the Iceberg REST Catalog API.

Together, these capabilities break down format silos and set Unity Catalog apart as the only catalog that delivers truly open, unified governance and interoperability. Check out our blog on Iceberg supportto learn more about these announcements.

Expanding Unity Catalog to business users

Data platforms shouldn't stop at the technical user. Business users need a clear, consistent way to find, trust, and work with data. Unity Catalog now offers a unified foundation for business context to bridge the gap between data and business teams.

Unity Catalog Metrics: One semantic layer for all data and AI workloads

Inconsistent metric definitions across tools and teams have long caused confusion, misalignment, and a lack of trust in data. Unity Catalog Metrics, now in Public Preview on AWS, Azure, and GCPand Generally Available later this summer, solves this by making business metrics first-class assets in the lakehouse. Unlike metrics defined only in the BI layer, which limit reuse and integration, defining metrics at the data layer makes business semantics reusable across all workloads, like dashboards, AI models, and data engineering jobs. Unity Catalog Metrics are also fully addressable via SQL to ensure that everyone in the organization can have the same view of metrics, irrespective of what tool they choose.

• Define once, use everywhere:Create metrics once in Unity Catalog and use them across AI/BI Dashboards, Genie, Notebooks, SQL, and Lakeflow jobs. Upcoming integrations will extend support to BI tools like Tableau, Hex, Sigma, ThoughtSpot, Omni and observability tools like Anomalo and Monte Carlo.
• Governed and auditable by default:Certified metrics come with auditing and lineage out of the box, enabling trusted, compliant insights across teams.

New curated discovery experiences with intelligent insights

To fully empower business users, you must make trusted data easy to find, understand, and use. Unity Catalog is extending its business-aware governance with a new Discover experience, now in Private Preview, a curated internal marketplace of certified data products organized by business domains like Sales, Marketing, or Finance.

AI-powered recommendations and data steward curation help surface the highest-value assets, such as metrics, dashboards, tables, AI agents, and Genie spaces that are enriched with documentation, ownership, and usage insights. New intelligent signals highlight data quality, usage patterns, relationships, and certification status, helping users quickly assess trust and relevance. Plus, with Databricks Assistant built in, users can ask natural language questions and get clear, context-aware answers based on governed metrics.

We're also introducing new intelligent capabilities across Databricks to make data discovery easier and more intuitive, wherever users work in the platform. Powered by Unity Catalog, these features help teams find trusted data faster and understand its context at a glance.

• Domains (Coming soon):Organize data by business area to align discovery with the organization's operations.
• Certifications and Deprecation Tags (Beta):Signal data trust and business relevance across datasets, metrics, and dashboards. Tagged assets prominently display their status in authoring surfaces like the SQL editor, keeping data quality signals visible throughout the user workflow. Certifications and deprecation tags are available as a part of Tag Policies Beta.
• Request for Access (Public Preview):To streamline delivery, users can instantly request data access directly to the asset.
