Which statement best describes how Scatter-Gather affects results?

• A. Scatter-Gather aggregates results from all branches into a single collection.
• B. Scatter-Gather preserves results in separate branches and does not aggregate.
• C. The aggregation is not possible without an explicit join.
• D. It can only aggregate results from HTTP endpoints.

Answer: (A)

Scatter-Gather runs multiple branches in parallel and then combines their outputs into a single collection. This means all results from the different paths are gathered together, providing one aggregated result instead of separate, branch-specific outputs. It’s not limited to HTTP endpoints; any compatible endpoint or processor can contribute to the aggregation. Also, you don’t need to use an explicit join for the aggregation—the pattern handles bringing the results together as part of its behavior.
