B) Each write to the orders table will run deduplication over the union of new and existing records, ensuring no duplicate records are present.
C) Each write to the orders table will only contain unique records; if existing records with the same key are present in the target table, these records will be overwritten.
D) Each write to the orders table will only contain unique records; if existing records with the same key are present in the target table, the operation will tail.
