There are 3 ways by which we can remove the duplicate records
1. By using remove duplicate stage. We have control here on which record we want to remove it's first or last. There is option record to retain in remove duplicate stage where we select first or last option.
2. By using sort stage. there is option allow duplicate in sort stage. We set this option true when we want duplicate records & If we want unique records we set it to the false
3. By in-line sorting. In Partition tab of any stage when we select key base partition tech. then perform sort option will enable if we check this option next 2 option will enable which is stable & unique if we select stable that means we allow duplicate records & if we select unique that means we remove duplicate records and getting unique records
