Announcing Public Preview of AI Generated Documentation In Databricks Unity Catalog

Streamlining data documentation and discovery with Generative AI
Share this post

Today, we are excited to announce the public preview of AI generated documentation in Databricks Unity Catalog. This feature leverages generative AI to simplify the documentation, curation, and discovery of your organization's data and AI assets by automating the addition of descriptions and comments for tables and columns. 

In today's data-driven landscape, where data is the bedrock of informed decision-making, establishing a solid foundation for teamwork hinges on seamless data discoverability and clarity. Yet, data teams often grapple with a crucial challenge: the absence of comprehensive data descriptions, creating a lack of contextual understanding. This shortfall impedes users from fully harnessing data's potential, underscoring the need for simplified data descriptions to bridge these gaps.

Furthermore, the absence of adequate metadata and descriptions for tables and columns compounds the issue, resulting in several challenges:

  • Data ambiguity: The lack of clarity surrounding the purpose and content of tables and columns can significantly hinder users' decision-making capabilities.
  • Manual burden: Data owners shoulder the responsibility of manually appending descriptions and comments to furnish essential context for their assets, a crucial requirement for fostering collaboration among teams.
  • Inefficient data exploration: Users frequently find themselves compelled to rely on complex queries to extract insights from the data, leading to the consumption of valuable time and resources.
  • Poor data quality: Inadequate or inaccurate documentation can give rise to misunderstandings, data errors, and compromised data quality. Remarkably, It is estimated by IDC that data analysts expend up to 80% of their time preparing and cleaning data, often stemming from inadequate data documentation, including missing descriptions.

Enhancing efficiency and accelerating insights with AI generated documentation in Unity Catalog

To address these challenges and assist in scenarios where data owners might lack sufficient context to add descriptions, Unity Catalog now suggests descriptions for tables and columns. Users can opt to accept these suggestions or adjust them as needed, ensuring an assistive and user-friendly experience. 

How it Works

  • Data exploration: When users navigate to the Catalog Explorer and access a table they own or manage, they will be presented with auto-generated metadata for the table and its columns.


  • User review and editing: Users will have the ability to review, edit, or accept the generated metadata. This step ensures that the descriptions align with the specific use case and domain knowledge.

  • Metadata storage: Once the user approves the generated documentation, it is saved within Unity Catalog. This documentation can then be used to support data consumers in various ways such as efficient search based on the auto-generated description. 

Using AI-powered documentation in Unity Catalog offers several advantages:

  • Time and resource efficiency: The automation of documentation generation saves time and reduces the manual effort required for data description.
  • Simplified data exploration: Users can quickly understand the content and purpose of tables and columns, reducing the need for complex queries
  • Enhanced data clarity: Accurate and comprehensive descriptions help ensure data clarity and prevent misunderstandings.
  • Improving Databricks search The generated metadata supports table search within your workspace, improving the discoverability of relevant data for all your data use cases.
  • User control: Users retain control over the documentation process, with the ability to edit and customize descriptions to better match their specific requirements.
