Pipeline Mapping
The Pipeline feature provides a graphical representation view of data and enables mapping between flow service's user input, and connectors or services. Pipeline is the general term that is used to refer to the data structure in which the input and output values are maintained for each step of a flow service. The pipeline starts with the user-defined input to the flow service and collects inputs and outputs from every step to the next step in the flow service. When the flow service runs, the pipeline has access to data until the previous step's output.
Pipeline page
The Pipeline page displays an interface for mapping the input and output
fields. You can access the Pipeline page by clicking the mapping icon (
) on the flow services step. The
Pipeline page appears only when an operation of the connector or service is
selected. If a connector is present, an account must be configured.. The flow service generates the
fields based on the operation and the service or connector selected. You can define the input or
output fields in the Input and Output section and map them
to the service or connector fields.
The Pipeline page has the following columns:
-
Pipeline Input - Displays the results from the previous step. For the first step, the input fields that are defined in the Define IO section are listed. The fields that are listed in the Pipeline Input column are sent as inputs to the Service Input fields.
- Service Input - Displays input fields of the service or connector that is selected in the step.
- Service Output - Displays the output fields of the service or connector that is selected in the step.
- Pipeline Output - Displays the results that are produced for the step. These results are sent as inputs to the next step's Pipeline Input . The last step results indicate the output of the pipeline.
You can map the fields in the following order:
- Pipeline Input fields to Service Input fields.
- Service Output fields to Pipeline Output fields.
