Hi All - I am new to Reltio Platform and need help with a pretty basic operation. I have 10M profiles already loaded and mastered and I need to add 3 new ID attributes and populate these values for one of the source system (source A). One option is to add new attributes and reload the file (source A) again, but I want to see the feasibility in Reltio if I can bulk update by providing just 4 fields, Unique Key(Crosswalk ID for source A) and 3 new attributes in a file and just run that file to do bulk update.
Prepare the file and use the console data loader with Partial Override options.
