In the new version 5.4, I get a message saying to use concatenate action instead of aggregation.
Please don’t deprecate the ‘concatenate’ option in the aggregate action.
I have a lot of projects using concatenate and count distinct or min/max (len text field) in the same transformation.
Migration would oblige me to split the tables, make aggregations in parallel then join the results.
In dozens of text analytics projects, I use this transformation around 60 times.
