▸View details & rubric context
Change Data Capture (CDC) identifies and replicates only the data that has changed in a source system, enabling real-time synchronization and minimizing the performance impact on production databases compared to bulk extraction.
Native support exists but is limited to key-based or cursor-based replication (e.g., relying on 'Last Modified' columns), which often misses deleted records and places higher load on the source database than log-based methods.
▸View details & rubric context
Incremental loading enables data pipelines to extract and transfer only new or modified records instead of reloading entire datasets. This capability is critical for optimizing performance, reducing costs, and ensuring timely data availability in downstream analytics platforms.
Native support exists for basic column-based incremental loading (e.g., using an ID or Last Modified Date), but it requires manual configuration and often fails to capture deleted records or handle complex data types.
▸View details & rubric context
