In a Scatter-Gather flow, how are the HTTP requests dispatched to the routes?

• A. They are dispatched sequentially.
• B. They are dispatched in parallel to the routes.
• C. Only the first route is dispatched.
• D. Routes are chosen based on payload type.

Answer: (B)

In a Scatter-Gather flow, the message is split into several branches and each branch is sent to a different route simultaneously. This means the HTTP requests are dispatched in parallel to the routes, not one after another. The responses from the routes are then gathered (often by an aggregator) to produce a single combined result. This parallel dispatch is what makes Scatter-Gather efficient when multiple independent services can be contacted at the same time.
