How can flows be triggered asynchronously from a parent flow?

In MuleSoft, if you want to trigger flows asynchronously from a parent flow, the Async scope is designed specifically for this purpose. When you use the Async scope, it allows the parent flow to continue its execution without waiting for the child flow to complete. This is particularly useful in scenarios where a long-running process might delay the execution of subsequent steps in the parent flow. By using the Async scope, the child flow can operate independently, and the parent flow can handle other tasks simultaneously, leading to improved performance and responsiveness of the application.

The design of the Async scope enables scalability and efficient resource usage, as it facilitates parallel processing without blocking the main flow. Essentially, this approach is beneficial for scenarios that require non-blocking behavior, such as event-driven architectures or real-time processing where the timing of operations is crucial.

While the Call scope is used to call another flow synchronously, meaning the parent flow waits until the child flow finishes executing, the Parallel scope can run multiple tasks without defining the workflow in a way that allows for true asynchronous behavior. The Sync scope, on the other hand, is not applicable for asynchronous triggering as it waits for tasks to complete before proceeding, which contrasts with the desired behavior in this scenario. Therefore, the Async scope is
