Incremental Materialization

Incremental models enable dbt™️ to selectively insert or update records in a table based on changes since the model's last execution.

Advantages:

  • Improved efficiency: Significantly reduces build time by processing only new or modified records.

Disadvantages:

  • Increased complexity: Requires additional configuration and is considered an advanced dbt™️ feature. (For more detailed information, refer to the dedicated guide on implementing incremental models.)

Best Practices:

  • Ideal data type: Most effective for event-style data sets.

  • Performance optimization: Consider implementing incremental models when you notice your dbt run operations becoming excessively time-consuming.

  • Implementation timing: It's recommended to start with simpler materialization strategies and transition to incremental models only when necessary for performance reasons.
