DataWeave FunctionDefinition Syntax

To define a function in DataWeave use the following syntax:

fun myFunction(param1, param2, ...) =

The fun keyword starts the definition of a function.

myFunction is the name you define for the function.

Function namesmust be valid identifiers.

(param1, param2, â€¦ , paramn) represents the parameters that your function accepts.

You can specify from zero to any number of parameters, separated by commas (,) and enclosed in parentheses.

The = sign marks the beginning of thecode block to execute when the function is called.

						A. An Array of the three Mule event Objects
						B. An Object containing all three Mule event Objects
						C. An Array of the three JSON payload Objects
						D. An Object containing all three JSON payload Objects
						
						
						
					
					
						

						Full Access

						
							
								Answer:
							
							
								
							

														
								
									Explanation:
								
								
									Correct answer isÂ An Object containing all three Mule event Objects
The Scatter-Gather component is a routing event processor that processes a Mule event through different parallel processing routes that contain different event processors. Each route receives a reference to the Mule event and executes a sequence of one or more event processors. Each of these routes uses a separate thread to execute the event processors, and the resulting Mule event can be either the same Mule event without modifications or a new Mule event with its own payload, attributes, and variables. The Scatter-Gather componentthen combines the Mule events returned by each processingroute into a new Mule event that is passed to the next event processor only after every route completes successfully.
The Scatter-Gather component executes each route in parallel, not sequentially.Parallel execution of routes can greatly increase the efficiency of your Mule application and may provide more information than sequential processing.
