Can you give the multiple rows an id and use that ? In your example , can
you assign a user-group id for each type of user (or maybe a map with
attributes if a user can belong to multiple groups), and then process using
that attribute or id ?
(I might not have understood the problem correctly, example of input and
output data might help)

popular in certain user groups, which means that I want to find items which
got many successive hits from users from that group in a short period of
Until now I only worked on the rows in an isolated manner, that is items
could be filtered or modified, without any knowledge of other records, but
this now requires to consider multiple records, and I have no clue as to how
approach this problem.

Any suggestions?
