Medallion Architecture Skill

Overview

The medallion architecture (also called multi-hop architecture) is a design pattern for organizing data in a lakehouse using three progressive layers:

• Bronze (Raw): Ingested data in its original format
• Silver (Refined): Cleansed and conformed data
• Gold (Curated): Business-level aggregates and features

When to Use This Skill

Use this skill when you need to:

• Design a new data pipeline with proper layering
• Migrate from traditional ETL to lakehouse architecture
• Implement incremental processing patterns
• Build a scalable data platform
• Ensure data quality at each layer
