   @BigRantLing ,Hi,
   Thanks for your help. I think it partially solve my problem by using filtered aggregator. But it cannot do the else part. For example column_A has hundreds of enum values, I want to calculate something if column_A = a_1, something else if column_A = a_2, the rest if column_A not in (a_1, a_2). Anyway, thanks for the instruction.
