DataHub UI​

Ask DataHub is coming soon to the DataHub UI, providing seamless access to AI assistance while browsing your data catalog.

Customize Ask DataHub​

As of v0.3.15, you can customize how Ask DataHub responds to queries by configuring custom instructions. These are injected into AI context to tailor the AI assistant's behavior to match your organization's specific needs, terminology, and guidelines.

Configuring Custom Instructions​

To configure custom instructions:

  1. Navigate to Settings > AI in your DataHub instance
  2. Locate the Ask DataHub section
  3. Enter your custom instructions in the Instructions field

That's it!

Custom base prompts can be used to:

  • Define response style and tone
  • Define organization specific terminology or terms
  • Guide the model on how to navigate Glossary Terms, Tags, Domains, and properties.
  • Guide the assistant toward specific of recommendations (e.g. helping differentiate production over staging assets)

Default Organization View​

By default, Ask DataHub applies your organization's default Search View (if one is set). This means the assistant will prioritize finding assets from a narrower set of assets, enabling it to separate the signal from the noise by default.

This ensures that Ask DataHub's responses are always relevant to your team's specific data landscape, without requiring additional filtering in your queries.

Note

After updating custom prompts or organization view settings, it may take up to 5 minutes for changes to take effect.

How It Works​

Ask DataHub leverages your complete metadata graph to provide intelligent, context-aware responses. The AI assistant considers:

  • Asset names, descriptions, and documentation
  • Lineage relationships (upstream and downstream)
  • Ownership and domain information
  • Usage patterns and popularity metrics
  • Data quality and assertion results
  • Tags, glossary terms, and classifications
  • Schema information and sample values
