In the exercise, at which transformer do the address features stop (or get blocked at) when running with breakpoints?

• A. AttributeSplitter
• B. AttributeManager
• C. StringReplacer
• D. FeatureJoiner

Answer: (D)

When you run with breakpoints, the translation pauses at the boundary of the transformer you set. The place where address features stop waiting is the transformer that combines two input streams: the FeatureJoiner. This transformer brings together related features from separate streams by matching on a join key. It often buffers one side’s features until a matching feature arrives from the other side, so with breakpoints you’ll see the address features appear to stop or queue up right at the joiner. The other transformers listed operate on a single feature stream and don’t require coordination between two streams, so they don’t inherently block in the same way at breakpoint times.
