A brief reminder of how sampling works
When a recipe is created an initial sample is automatically generated at the same time. After that, additional samples can be generated from the context panel on the right side of the Transformer page as needed.
Sample jobs are independent job executions. When a sample job succeeds or fails, a notification is displayed for you.
Generating a new sample
Display the Samples pane from the Transformer Grid. Choose the sample method desired, and the scope (quick or full). The sample is generated and then the user can choose whether or not to load it.
As you develop your recipe, you might need to take new samples of the data. For example, you might need to focus on the mismatched or invalid values that appear in a single column. Through the Transformer page, you can specify the type of sample you wish to create and initiate the job to create the sample. This sampling job occurs in the background.
