問題文

One flow must route by content, transform the data, and handle errors. How do these concerns fit together in a single flow?

選択肢

1. A choice router directs the event by content, a DataWeave transform reshapes the payload, and an error handler decides whether failures are continued or propagated.
2. These three concerns have no way of being combined in a flow, which means a team must pick just one of them for each of the flows that it builds.
3. A single DataWeave transform performs the routing, the transformation, and the error handling all at once, because reshaping the payload is what routes events and catches them.
4. Routing, transformation, and error handling cannot appear in the same flow; each must be a separate application that the others call over the network on each request.
