Setting the event coordination property

Use the Event coordination property for controlling how message collections are propagated from the Collector node.

Before you start:

This topic assumes that you have already created a message flow that contains a Collector node. For more information, see Creating a flow that uses message collections.

In addition to the dynamic input terminals that you can add to the Collector node, there is a static input terminal called Control. The purpose of this terminal is to allow an external resource to trigger the output from the collector node. Details are controlled through the Event coordination property settings.

Incomplete message collections that have exceeded the value for the Collection expiry timeout are immediately propagated to the Expire terminal, regardless of how you configure the Event coordination property.

To configure Event coordination:

Open the message flow that contains the Collector node.
Right-click the Collector node and select Properties.
Click the Advanced tab.
Set the Event coordination property on the Collector node. Select from the following options:
- If you select Disabled, messages to the Control terminal are ignored and message collections are propagated when they are complete.
- If you select All complete collections, complete message collections are held on a queue. When a message is received on the Control terminal, all message collections on the queue are propagated to the Out terminal.
- If you select First complete collection, complete message collections are held on a queue. When a message is received on the Control terminal, the first message collection on the queue is propagated to the Out terminal. If the queue is empty when a message arrives on the Control terminal, the next message collection that is completed is propagated to the Out terminal.

You have completed configuration of the Collector node.

Next: if you have configured your Collector node to use control messages, see Using control messages with the Collector node.
