ccaominh commented on issue #9488: Match GREATEST/LEAST function behavior to other DBs URL: https://github.com/apache/druid/pull/9488#issuecomment-596815921 > can you explain what are those `other databases ` and if it is not a standard SQL why we have to expose the same name ? I've updated the description with references to what some other databases do. The functions aren't part of the standard, but they're available in many databases. > How about actual user using this ? would this be backward compatible ? The current behavior was added by https://github.com/apache/druid/pull/8719. Since that change is not in a druid release yet, we don't need to worry about backward compatibility.
