The team needs a new field that equals Amount multiplied by a fixed commission rate, calculated from values already on the same opportunity row. Which dataflow node fits?

選択肢

1. The computeExpression node, which derives a new field from other fields on the same row.
2. The augment node, which multiplies fields such as Amount and the commission rate value when it joins two streams.
3. The computeRelative node, because any calculated field must look across ordered rows. On that reading, even Amount times a fixed rate would need the rows sorted before it could be evaluated.
4. The aggregate step, which computes the commission field by grouping the opportunities into monthly rate buckets.
