Recipient component

The Recipient component allows you to route messages to a number of dynamically specified recipients.

Configuration​

Example usage of Recipient component

The recipients will receive a copy of the same Exchange, and the component will send them sequentially to the recipients. Every recipient has a label on its connection that indicates the order in which the component will send the messages. Check the Exchange pattern option to how the component can route the messages.

Re-arranging outputs

While disconnecting the outputs of a recipient the order can change. Please verify the order is still to your liking or disconnect all outputs and reconnect them in order again.

Exchange pattern​

Options

  • One way
  • Request reply (default)

Description

The routing of the messages will always be sequential in the order that is shown on the connection labels. This option only has an impact on when the message is send to the next recipient.

By default the component will use the Request reply option. This means that the component will only send the message to the next recipient when the current recipient has processed the message. The component basically sends the message to one recipient at a time. This is the option you want to select when the order really matters, for example: recipient number 1 has to process the message before it can be sent to recipient number 2 and so on. The response to the caller will be the result of the last recipient that is called. This label of the last recipient gets a blue color. If an error occurs in one of the recipient routes, the subsequent routes will no longer be executed.

When the recipients don't have to wait on each other before processing the message you can select the One way option. The specified order is still respected, but the component won't wait until the message is fully processed by one recipient before sending it to the next. This option will also improve the perfomance of the flow, because multiple recipients can process the message at the same time. The response to the caller will be the exchange that goes into the Recipient component. If an error occurs in one of the recipient routes, the other routes will not be affected by this and will be executed as usual.
