            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
