SchemaSentinel

Schema change impact analysis to prevent broken dashboards

Problem

When source tables drop or rename columns, data engineers struggle to trace end-to-end impact on dbt transformations and BI reports, often leading to broken dashboards.

Solution

Connects to data warehouses and BI tools, automatically parses schema change impact chains, visualizes downstream affected objects, and generates fix suggestions.

Users

Data engineers and analytics engineers

MVP

Parse dbt project metadata; diff schema changes; show downstream report dependency graph; flag affected fields
