Use the Delta Lake MERGE INTO statement to update the silver layer with new or changed records from the bronze layer, ensuring data quality by enforcing schema constraints.

Implement a custom deduplication logic using a combination of SELECT DISTINCT and OVERWRITE statements, which may increase processing time and costs.

Leverage the Delta Lake WRITE statement with the overwriteSchema option to ensure schema enforcement and prevent data quality issues, but this may not handle deduplication effectively.

Utilize the Delta Lake READ and WRITE statements with the append mode to incrementally process data while maintaining data quality and deduplication, optimizing for cost and performance.
