Medallion + Data Mesh Architecture
The Medallion + Data Mesh architecture enables you to map tables to both Medallion layers and business domains, combining layer-based structuring with domain-driven classification. Tables are assigned to Medallion layers (Bronze, Silver, and Gold) while being aligned to business domains, ensuring both structured organization and domain ownership.

Mapping Tables to Medallion Layers and Domains
You can classify tables by assigning them to Medallion layers and mapping them to business domains.
- Configure Classification Rules: Manually assign tables to Medallion layers (Bronze, Silver, Gold) and map them to appropriate domains.
- AI-Assisted Classification: Automatically classify tables into suitable layers and domains using AI-driven recommendations.
- Create Data Product: After classifying tables, click Create Data Product to design and build governed, domain-aligned data products with rich business and technical context.
Configuring Classification Rules
To manually classify tables:
- Click + Configure Classification Rules.
- In the Map Tables window, select the required tables.
- Assign each table to a Medallion Layer (Bronze, Silver, or Gold), Domain, and Table Type.
- Click Add Tables.
- In the Create Job Name window, enter a Job Name.
- Click Submit.
A confirmation message is displayed once the tables are successfully classified.
AI-Assisted Classification
To automatically classify tables:
- Click + AI-Assisted Classification.
- The system analyzes the tables and assigns them to appropriate layers and domains.
A confirmation message is displayed once the classification is complete.
Viewing Classified Tables
After classification, the system generates the Medallion + Data Mesh – Table Classifications view, providing a consolidated summary of the classified data.
Classification Summary
The summary section provides an overview of the classified data, including:
- Distribution of tables across Medallion layers (Bronze, Silver, and Gold)
- Distribution across table types, such as Dimensions and Facts/Aggregates
This helps you quickly assess how tables are organized across layers and data types.
Viewing Table Details
You can further explore the classified data in the Medallion Architecture Layers section. Each layer—Bronze (Raw Data), Silver (Cleansed & Conformed), and Gold (Business Ready)—is displayed with the total number of tables assigned.
Expand any layer to view detailed table-level information such as data sources, domain, number of columns, PII fields, and more.
You can also use filters to refine the view based on Domain, Layer, Table Type, or Data Source.
Creating Data Product
Once the tables are classified into domains, you can create data products directly from this page.
- Click Create Data Product.
- Proceed to the Data Product Builder to design and define domain-aligned data products.
This allows you to move from classification to creating governed, domain-aligned data products with rich business and technical context.
