Thread Count: The parallel connection count that will be opened on this database when discovering sensitive data.
The default value seen when the page is opened is 10. The default value can be changed by setting the sdd.thread.count.default parameter in the System Config Manager. The minimum value of the count is 1 and the maximum value can vary.
Sample Data Count: Sample data count to be scanned for sensitive data discovery. For example, if this value is 10, the first 10 rows of the table columns are scanned.
Expected Match Percentage: The discovered data is listed in the search results when the scanned data is matched in rate with the expected match percentage.
