I am grouping on a key (in this scenario the is a parsed filename) in order to evaluate the state of a file because there are multiple log entries for each step that happen to a file. For some steps there are textual fields that are provided that can be parsed that I would like to do a max on in the grouping but max only supports numerics. First/Last will not work because these values are not in a every log entry. Is there a way to accomplish a MAX on textual values?
