It creates a lot of output - one output row per row and rule. So if you have 1000 rows and 50 rules, the detailed output will create 50000 rows - but on the other hand you have the ability to easily find out what data passed or failed the checks. You can of course also write the detailed data to a database or file or further process it.
If you don't need the details, then simply do not connect a second step.
