Which pair of transformers would you use to detect and report data type changes?

• A. ChangeDetector and TypeChangeDetector
• B. SchemaScanner and AttributeCreator
• C. TypeChangeDetector and SchemaScanner
• D. AttributeCreator and TestFilter

Answer: (A)

In this scenario you want to catch when an attribute’s data type changes and then report that change. TypeChangeDetector is built to watch the data type of an attribute as features flow through the workspace and to flag when that type differs from what was seen before. To turn that detection into actionable reporting, you pair it with a ChangeDetector, which captures the moment a feature reflects that detected change and can route or log it for reporting. Together, they provide both the signal that a type change occurred and a means to report it downstream. Other options don’t fit as neatly. SchemaScanner is about discovering or monitoring the structure of the schema itself, not actively reporting data-type changes as features pass through. AttributeCreator applies or creates attributes but doesn’t detect changes. TestFilter can route or filter features but doesn’t produce the detection signal for data type changes.
