Implement a batch process that periodically scans the entire dataset to identify changes, marks records for deletion, and then performs a delete operation, ensuring data integrity at the cost of increased operational overhead.

Use the merge method to perform an upsert operation with a deletion flag, followed by a separate delete operation to remove the flagged records, balancing operational overhead and data integrity.

Leverage the merge method to perform an upsert operation with a deletion flag within a single transaction, efficiently handling updates and deletes while minimizing operational overhead and ensuring data integrity.

Directly delete records from the Delta table without using the CDF, relying on external logging for change tracking, which minimizes operational overhead but risks data integrity.
