Review Comment:
   i think there is diff with original code. we only want put **PROJECT** 
slot's unique id into outputColumnUniqueIds to avoid materialze slot only in 
filter when use inverted index. but slot.isMaterialized = true include slot 
only in filter. u could debug with sql like `select c1 from t where c2 = 3`, 
outputColumnUniqueIds 
    should only contain c1's unique id
