Incremental Update in Fabric from External Delta Tables
- 1 year ago
Hi PDG_VL To implement incremental updates from external Delta tables into a Fabric Lakehouse Bronze layer, use a timestamp column to filter new or modified rows since the last refresh. Perform upserts using Delta Lake’s MERGE functionality to handle updates and deletes efficiently. Maintain a change log table for historical tracking, appending only new records during each refresh. Optimize by partitioning Delta tables and processing only relevant partitions to reduce resource usage.
