How is the event routed in a Scatter-Gather when it contains a payload that is an Array of Objects?

In a Scatter-Gather pattern, the primary mechanism involves sending the entire event to all specified routes simultaneously, rather than sequentially. This means that all configured processors within the Scatter-Gather will receive and handle the same input event concurrently.

When the payload consists of an Array of Objects, each route in the Scatter-Gather can process the entire array independently and in parallel. This approach enables faster processing and improved performance because it allows multiple routes to be executed at the same time. The parallel execution is particularly valuable in scenarios where each route can operate independently without depending on other routes, which helps in optimizing resource utilization and reducing overall latency.

The emphasis here is on the simultaneous processing of the same payload across different routes, which is the defining characteristic of the Scatter-Gather pattern in MuleSoft. This is distinct from the options that suggest sequential processing or splitting the event, which do not accurately represent how Scatter-Gather functions.
