• Iterate ID - Can be used to identify messages created by the iterate mediator. Useful when defining nested iterate mediators.

• Sequential Mediation - Specifies whether split messages should be processed sequentially (True) or in parallel (False). If True is selected, you may experience a delay due to relatively high resource consumption. Therefore, it should be selected only when the order of the message is important. If False is selected, you may experience better performance. However, it is advisable to increase the size of the thread pool to enable the backend to handle the processing better. Default value is

  "false"

  False (parallel processing). 

  Excerpt
  hidden true
  Information was added to this description with reference to the question "How can i decide whether to use sequential="true" or sequential="false" ?" in the /wiki/spaces/FAQ/pages/37781537 page.

• Continue Parent -Specifies whether the original message should be continued or dropped.
  • True

  • False

    Info
    title Tip
    This is default to false.

• Preserve Payload -Specifies whether the original message should be used as a template when creating the split messages.
  • True

  • False

    Info
    title Tip
    This is default to false.

• Iterate Expression - XPath expression that matches the elements, which you want to split the message from.
• Attach Path - To form new messages, you can specify an XPath expression for elements that the split elements are attached to (as expressed in Iterate expression).

In this scenario, the Iterate Mediator splits the messages into parts and processes them asynchronously. See also Splitting Messages into Parts and Processing in Parallel (Iterate/Aggregate).
