Testing and updating the pattern-based parsing configuration
Testing and updating the pattern-based parsing configuration
Test a parse asset to verify that data flows through the asset in the ways that you expect. You can then update the asset with the pattern for any name that the test failed to parse. The asset stores the patterns that you add and includes them in the pattern logic that the Parse transformation uses at run time.
You can update the asset with pattern data, and you can update the asset both with patterns and with the names in your input data that are associated with the patterns.
You might update an asset exclusively with pattern data when you test the asset before you add it to a Parse transformation. You might update an asset with both pattern data and name data after you run a mapping with the Parse transformation and review the output from the transformation.
Iterative testing
Testing the asset and updating the pattern-based logic for a source data set can be an iterative process. You might test the asset first with a sample of your source data and later test the asset with the name data and associated patterns that you read from the transformation output data.
