User Story:
As a data analyst who uses Dataiku Visual Join and Window Recipes, from time to time I'd like to be able to concatenate values as JSON Arrays. (Not simply with a separator based approach.). This would allow for quicker use of Join and Window Recipie. Maybe not requiring a followup prepare recipie
COS:
Notes:
Many times I will concatenate with the separator "," and then create a seperate recipie to add the [" and "] on the results of a concatenate.
