Re: Find duplicates

Is finding duplicates not possible with Talend Data Preparation?

Re: Find duplicates

The match function can work, when matching with a specific value or between columns. We don't provide (yet) matching across rows.
Lookups may also help to highlight exact matches between datasets.
