Incremental Processing with DBT in Luce

The Challenge: Efficient Historical Data Processing

Organizations face the critical challenge of processing large volumes of historical data efficiently while maintaining data freshness and tracking changes over time. Traditional full-refresh approaches consume excessive resources and time, while simple incremental processing often misses important historical changes.

Our incremental processing approach leveragess DBT's advanced incremental models, SCD Type 2 tracking, and snapshots to achieve materially faster refreshes while maintaining complete historical accuracy.

Incremental Processing Architecture: Historical Tracking

Our solution delivers materially faster refreshes** with efficient incremental processing. Here's the architecture:

Processing Layer

• DBT Incremental Models: Efficient delta processing
• SCD Type 2 Tracking: Complete historical change tracking
• DBT Snapshots: Point-in-time data reconstruction
• Change Data Capture: Real-time change detection

Optimization Layer

• Partitioning Strategy: Time-based data partitioning
• Clustering Optimization: Query performance optimization
• Incremental Logic: Smart delta processing
• Historical Preservation: Complete audit trail
