This scenario presents a Job that checks the type, nullability and length of data from an incoming flow against a defined reference schema, and displays the validation results on the Run console.

The incoming flow comes from a simple CSV file that contains heterogeneous data including wrong data type, data exceeding the maximum length, wrong ID and null values in non-nullable columns, as shown below:
