What happens when you hide columns in an Aggregate?

When you hide columns in an Aggregate, it specifically impacts the visual representation of the output, allowing developers to focus on only the necessary data. This means that hidden columns do not appear in the output but are not removed from the processing context of the Aggregate itself. Developers often hide columns for clarity and better management of the data being handled in the application, especially during development.

Hiding columns does not optimize the Aggregate since the operations are still performed on all the columns, whether they are visible or not. Empty columns in the database are not automatically hidden as this action is performed manually by the developer. The hidden columns remain part of the overall data structure defined by the Aggregate, and their exclusion from the output helps maintain a streamlined presentation of the resultant data specifically tailored to the app's requirements.
