I want to have groups corresponding to the equivalent of 'SELECT DISTINCT x' query. Then I want each item assigned to a group of it's value of x. For example:
'SELECT DISTINCT x' -> ['a', 'b', 'c']
'SELECT x,y' -> [ ['a', '1'], ['a','2'], ['b','3'], ['c', '4'], ['c','11'] ]

Then I have 3 groups: a has 2, b has 1, c as 2, then I want to set filerOnGroup to one of the groups. Is there a way to do this?
