      Description

      The expression can be as follows:

      1. a 1*col 1 + a 2*col 2 + ... + a n*col n + b, if sum(col 1),sum(col 2),...sum(col n) are defined
      2. case when filter 1 then expr 1
        when filter 2 then expr 2
        ...
        else expr N
        end, if filter 1,filter 2, ... filter N-1, and expr 1,expr 2,...expr N are supported

      There's a constraint for the filter. That is it's able to push down the related filters in case when.
