dbt and Atlas are not competing tools: dbt transforms data inside your schemas, Atlas manages the schema layer dbt sits on. What each one does with the same change, demonstrated on ClickHouse.

Which ALTER statements rewrite data on a large warehouse table, which ones are metadata-only, and how to block a destructive change with Atlas lint and a pre-migration check.
