How to Check Data on User Interface of Tableau Prep Builder When Sampled Data Does Not Contain Specific Data Required for Verification

When processing the large amount of data in Tableau Prep Builder, the data is sampled based on the Tableau Prep sample algorithm according to the following document.

• Set your data sample size
• Changing the data sample settings

However, we may want to check the results on the user interface regarding specific data. At this time, if the sampled data does not include that specific data, how can we verify it?

For example, assume that we connect to a table that has 2 million records. The number of rows loaded is equal to or less than 393,216 by default. 

If we would like to verify the data (ID = 1,000,000) but it is not included in the sampled data, how can we verify it?
