Emitter Subflows

The publishing emitter message flow is very similar to an action message flow. The role of the emitter flow is to create the message that is to be externally published. There is a standard template for emitter subflows: they must start with the BeginPublish subflow and terminate with the EndPublish subflow. In between these start and end flows, any arrangement of integration bus nodes is possible. Usually, only a single compute node is required and the emitter logic is implemented in the ESQL associated with this node.

The action subflow must be included in the overall wrapper flow that processes events for publication.

The following figure shows a typical emitter implementation.
