[GitHub] [phoenix] yanxinyi opened a new pull request #456: PHOENIX-4315 function Greatest/Least

yanxinyi opened a new pull request #456: PHOENIX-4315 function Greatest/Least
URL: https://github.com/apache/phoenix/pull/456
 
 
   Currently, COALESCE supports only 2 arguments.
   For instance, the GREATEST(expr1, expr2) is supported but GREATEST(expr1, expr2, expr3, ...) is not.
   Only implemented `GREATEST` for now, but if the list of arguments uses cases are needed from the open source community, We can do the optimization later. 
   If everyone is ok with this approach, I will create another patch for `Least` feature.
   :)
