Splitting a file into multiple files

Hi - I am new to Knime.  I have a CSV file with 20 million rows that covers 20 country data.  I need to create one CSV file per country using the column country as the newly created files.




Simple: File Reader -> Row Filter -> CSV Writer. Execute the workflow 20 times and change the filter setting in the Row Filter accordingly for each country.

Advanced: Use the "loop" nodes combined with flow variables to avoid manual configuration.

Thanks!  I got it working using group loop.
