When not to use an Event Emitter
Consider where you place an Event Emitter in your flow, and what data you choose to be stored in the event. Avoid placing an Event Emitter in the normal run path of a flow as this could affect performance by causing a large number of events to be generated.
In the following example flow, two event emitter primitives are used in the main path of the flow. The first event emitter will always run to notify that a message has been logged. The second event emitter will frequently be run to notify that the message has been routed to a service in the normal path of the flow. Both event emitters run in frequently used normal branch conditions of the flow.
