      Description

      Currently, Kylin supports 6 basic aggregation measure functions:
      Min/Max/Sum/Count/Avg/DistinctCount

      But there are also many other cases require to support more complicate measure expression, for example:
      COUNT(CASE WHEN so.ft = 'fv' THEN soi.sc ELSE NULL END) or Sum(if...)

      Or even more complicated measures like TopN and RawRecords

      To open this JIRA to tracking further implementation
