Aggregate snap - CONCAT function - optional delimiter

When using the CONCAT function in the Aggregate snap it delimits the records using ‘|’. We’d like to have the delimiter be configurable as well as optional.

In the meantime, you should be able to use the GroupByN snap with a “Group Size” of zero to collect all of the documents into a single object that you can reshape into an array and feed into the Array.join() method.
