Which Eventstream transformation allows you to rename columns?

• A. Expand & Manage Fields
• B. Filter & Manage Fields
• C. Join & Manage Fields
• D. Group By & Manage Fields

Answer: (D)

Renaming columns is a schema-shaping step, handled by the field-management part of a transformation. The Group By & Manage Fields transformation combines the grouping logic with a dedicated area to manage fields, which includes renaming columns as you shape the output. This makes it the best fit when you need to change column names while preparing data that’s being grouped or summarized.

The other transformations focus on different actions: expanding nested fields, filtering rows, joining streams, or performing grouping with other operations, but they don’t center on renaming columns as the primary way to shape the schema.
