Let's see how we can use that node. To do this, we will follow the following these steps:
Select the "FlowEngine Management" option from the menu:
Select the domain belonging to your user:
Once you are in the domain, drag a node of type "Start Dataflow" to the flow and double click on it to see its properties.
The following are the base properties:Name: The name that you want the node to have when viewing it within the flow.
Dataflows available: List of dataflows availables by the user
Dataflow: Dataflow selected in the previous box. This dataflow is the one that will be started. If msg.dataflowIdentification exists and has content, value this will be used insted of the base property.
Reset origin: If checked, it will reset the
...
origin's pointer. If msg.resetOrigin exists and has content, this value will be used insted of the base property.
Parameters: A list of properties sent to the dataflow. The value of each parameter can either be a static value (string) or
...
coming from a field of a msg (msg.)
If the incoming message has the property msg.parameters defined and it has content, its value will be used instead. The format of this field must be an JSON contaning key/value as follows:
msg.parameters = '{"query":"where field=”value”"}'
Run the dataflow
Whenever a message reaches the node, it will try to start the selected DataFlow. The result of the
...
operation, and its state
...
, will be shown in the msg.payload:
