問題文

A Scatter-Gather component has three routes, each calling a different backend. All three succeed. What does the payload look like after the component?

選択肢

1. The payload that entered the component, unchanged.
2. An object whose keys are the route positions and whose values are the messages that each route produced.
3. A flat array holding the three payloads in the order the routes finished, so the position no longer identifies the route.
4. The payload of the route that finished first, because the component returns as soon as one route has a result so that the slowest backend does not hold up the whole flow while the other results are discarded.
