dbt Defer: Speed Up CI/CD Pipelines and Slash Compute Costs by 75%
Implementing dbt's defer feature in CI pipelines dramatically accelerates builds and reduces cloud compute costs by 60–80%, as it reuses existing production artifacts and rebuilds only modified models instead of the entire dependency chain. By storing and referencing production manifest files, teams can achieve up to a 75% runtime reduction on small projects and cut 20-minute builds to under 5 minutes on enterprise-scale warehouses. Defer supports advanced patterns, including integration with local development and selective full refreshes, while requiring careful manifest and schema management to avoid pitfalls.
