What is a scatter-gather in MuleSoft?

The concept of scatter-gather in MuleSoft refers to a design pattern that enables a single message to be dispatched to multiple target endpoints concurrently. This functionality is particularly useful in scenarios where a service needs to call multiple APIs or systems to gather data or perform actions simultaneously.

When a message is sent through the scatter-gather component, it allows the processing of responses from various endpoints independently, enhancing the overall efficiency and performance of applications by utilizing parallel execution. After all the responses are collected, they can be aggregated or processed further as needed, providing flexibility in how data is managed.

This functionality supports a wide range of integration patterns, particularly those that require data from multiple sources to be combined into a single output, making it a powerful tool in the MuleSoft ecosystem.
