This feature is only available on PRO and Enterprise plans.
How it works
Custom backfill allows you to customize the cursor value for a specific job run. This is valuable when you need to reprocess data without running a Full Refresh.
For example, you want to reprocess all the data starting from 01/01/2026 because a new column was added or some records have been deleted.
Soft delete
You may enable the soft delete option in order to detect cases when records from your data source no longer exist. That is, records that are not found during the custom backfill execution will then be marked as deleted on your data warehouse.
