DEFINITION
Schema Drift Detection
Database Schema Drift Detection and Handling
Definition
Automated detection and handling of changes to database schemas (new columns, renamed tables, type changes). Critical for agents that maintain semantic layers, as schema changes can break queries and models.
Examples in the Wild
- Example 1:SLayer detects when a column is renamed and updates dependent models
- Example 2:Agent is notified of schema changes and can update semantic models accordingly
- Example 3:Prevents silent failures from stale model definitions
