Validate input/output data
This page provides examples of what your input and output data might look like in your stream’s Validate function. These views can help you troubleshoot and validate that the function works as intended. The images below show the input/output data from the Validate function in the example stream, Handling erroneous and duplicated records.
Validate is used in the following Example Streams:
Input data
The Input data window shows the raw data received by Validate from the previous functions in the stream. This view can help you verify the incoming data to be validated.
Output data
The Output data window shows a subset of the validated data. It will only show the data that has successfully passed the configured validation rules, allowing you to verify that the function has correctly applied the rules.
Validate in the example stream Handling Erroneous and Duplicated Records
The rule on the field userTechnicalId checks the following validations:
The field must be of type string
It must be exactly 36 characters long
It is required to be there
The rule on the field kWhCharged checks the following validations:
It is required to be there
The output shows two fewer records than the input. One of these records contains an invalid userTechnicalId, and the other does not have a value for kWhCharged.
Multiple outputs
If you choose to create a new output in the configuration, a second output will appear in the input/output data. In the example below, invalid records are sent both to Data Correction and forwarded to the configured output function.
