Which of these DataRaptor settings helps in preventing duplicate record creation?

• A. Lookup
• B. Default value
• C. Upsert key
• D. Disabled

Answer: (C)

The Upsert key setting is crucial for preventing duplicate record creation in DataRaptor. When you configure a DataRaptor with an Upsert key, you define a unique identifier for a record in the data source. During an upsert operation, the DataRaptor attempts to find a record that matches the Upsert key. If a matching record exists, it updates that record instead of creating a new one, thereby preventing duplicates. This approach ensures that the integrity of the data is maintained and that each record remains unique within the dataset.

Utilizing the Upsert key is a best practice when dealing with scenarios where data integrity is a priority, particularly when interacting with external systems or databases where duplicate entries can lead to data inconsistencies and errors.
