Data Schema Tracker – Monitor Schema Evolution¶

Purpose¶

Track and alert on schema evolution.

Technical Features¶

• Monitors:
• Added or removed columns
• Datatype changes
• Alerts on both intentional and unintentional schema changes
• Prevents silent schema drift that can break ETL pipelines or dashboards

Example Use Cases¶

• Identifying datatype changes (e.g., INT → VARCHAR) that may cause downstream errors
• Alerting data engineers before pipelines fail due to schema mismatches

Value¶

Keeps teams in control of fast-moving, evolving datasets.
