How can I mark a duplicate row instead of deleting it in magic ETL?
I use domo to handle metadata transformations for music tracks, and for publishing purposes it's important that I don't have any duplicate track titles. It can mess with the royalty payouts. So basically I want to mark a row as a duplicate based on specific values in columns/rows instead of deleting it. Ideally I'd love to make a new row titled "Has duplicates?" and if it does, assign the value to "YES" and if not, "NO." If it has duplicates, then I will know and I can go ahead and change the title before I submit it for publishing. So I want pretty much the exact same functionality as the delete rows tiles, where I can choose certain columns and it checks if there are duplicates, but instead of deleting duplicates after the first row, I just want it marked.

You could use the group by tile. Choose what fields make a row unique and include them in the group by fields. Then do a count as the group by aggregation. Then join that back to your data. Anytime there is a value of 2 or more, you'll know you have duplicates. You could then use a formula with a case statement to add a flag of "YES" or "NO" for duplicates if the value of 2+ isn't enough.
