- A. Entire event would be sent to each route in parallel
- B. Entire event would be sent to each route sequentially
- C. Incoming array objects would be split into three and each part would be sent to one route each in parallel
- D. Incoming array objects would be split into three and each part would be sent to one route each in sequential manner
Answer: A
Explanation:
Entire event would be sent to each route in parallel.
Scatter-Gather works as follows :
- The Scatter-Gather component receives a Mule event and sends a reference of this Mule event to each processing route.
- Each of the processing routes starts executing in parallel. After all processors inside a route finish processing, the route returns a Mule event, which can be either the same Mule event without modifications or a new Mule event created by the processors in the route as a result of the modifications applied.
- After all processing routes have finished execution, the Scatter-Gather component creates a new Mule event that combines all resulting Mule events from each route, and then passes the new Mule event to the next component in the flow.
