splits a payload into elements and processes them one by one through the components that you place in the scope.
The collection can be any supported content type (ie. application/json, application/java or application/xml)
**For Each does not modify the current payload - the output payload is the same as the input!
You can use this to set variables though |

Term
| When an outbound call is made during a flow, by using a request element (could be in a subflow) what happens to the attributes? |

Definition
attributes (including query parameters) are overwritten!
Note if the subflow does not have a request element, the query parameters are still accessible |

Term

Definition
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 component then combines Mule events returned by each processing route into a new Mule event that is passed to the next event processor only after every route completes successfully. Returns a collection of all the results. The collection is an Object of Objects. Each object contains attributes and payload from each Mule event returned |

dynamically routes messages through a flow according to a set of DataWeave expressions that evaluate message content. Each expression is associated with a different routing option.
Only one of the routes in the Chocie router executes, meaning that the first expression that evaluates to TRUE triggers that route's execution and the others are not checked. |

| The Round Robin router iterates through a list of two or more routes in order, but it only routes to one of the routes each time it is executed. It keeps track of the previously selected route and never selects the same route consecutively. For example, the first time Round Robin executes, it selects the first route. The next time, it selects the second route. If the previously selected route is the last route in the list, Round Robin jumps to the first route. |

| sync flow (or synchronous flow) |
|
Definition
processes messages SYNCHRONOUSLY relative to the flow that triggered its execution. While a synchronous flow is running, processing on the triggering flow pauses, then resumes only after the synchronous flow completes its processing and hands the message back to the triggering flow. However, unlike a subflow this type of flow does not inherit processing or exception strategies form the triggering flow.
Processes messages along a single thread which is ideally suited to transactional processing |
