What must be considered when updating a formula field in Data Cloud using the S3 Connector?

1. Data Cloud does not support updates

2. All records will update at the next refresh

3. A full refresh will occur

4. Only new records will be updated

The correct answer is: All records will update at the next refresh

When updating a formula field in Data Cloud using the S3 Connector, it is essential to recognize that all records will be updated at the next refresh. This process ensures that the formulas applied to the data reflect the most current values based on the latest data available in S3. The nature of how formula fields work relies on recalculating values whenever the data source is refreshed. Therefore, when changes are made to the formula field or its underlying logic, the entire dataset is revisited during the next refresh cycle, rather than only updating selective records. This approach helps maintain data consistency and integrity, as all records are brought in line with the new formula calculations uniformly. In contrast, other options incorrectly describe the impacts of updating formula fields. The idea of a full refresh is not explicitly correct in describing what happens in this context as a refresh naturally involves processing all records. The concept that only new records would be updated does not hold as the refresh mechanism affects the entire dataset, not just the new entries. Understanding these details is crucial for managing data effectively within the Data Cloud ecosystem.
