Github user cestella commented on the issue: https://github.com/apache/metron/pull/942 So, I would suggest rather than accepting a list of stats objects, `MAX` and `MIN` accept one of the following: * A StatisticsProvider object * A list of comparables Essentially, these two would both function: * `MAX(STATS_ADD(null, 1, 2, 3))` * `MAX([1, 2, 3])`
