rxin commented on issue #23304: [SPARK-26353][SQL]Add typed aggregate functions: max&&min URL: https://github.com/apache/spark/pull/23304#issuecomment-454296822 I'm kind of wondering whether it'd make sense to add these. It adds a lot of code which would incur some maintenance cost, and users can trivially implement these themselves, or just use the untyped version, and we don't need to spend time discussing whether these should follow SQL semantics or Scala semantics.
