Atlas vs dbt: Different Jobs, Better Together

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.

ClickHouse and dbt: Managing the Schema Layer

ClickHouse-specific decisions for a dbt project: MergeTree engine and ORDER BY on source tables, why changing ORDER BY rebuilds the table, schema-scope grants for dbt, and dimension data as code.

Drift Detection for Your Warehouse

Detect when a warehouse stops matching its checked-in schema while dbt keeps rebuilding models: what migrate status misses, how atlas schema diff reports drift, and what excluding dbt's database costs you.

Safe DDL on Large Warehouse Tables

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.

Schema Management for dbt Projects

Manage the schema layer a dbt project runs on with Atlas: databases, source tables, lookup data, roles and grants, with dbt's own models left to dbt through exclude patterns in atlas.hcl.
