With the Data Validator Snap (and the constraint that you've put), if no rows are returned, the snap (Data validator) will throw an error and the pipeline will fail. - or maybe that's the behavior that you want to achieve. 🙂
Another option that you can check is Filter Snap. If the filter expression evaluates to true, the document is passed through. If the filter expression evaluates to false, the document is dropped in the stream.
