   ### Description
   
   Currently date/decimal may cost too many times when evaluating predicate.
   Because they are customized class and can not be vectorized when evaluating.
   For decimal, I think we can convert it to int128, then evaluating it in vectorized way. The ```convert```  may be slow in current insert method, but I think we can try to vectorized it.
   For date, currently implemented using a 24-byte array, I think maybe we can convert it to a integer and then evaluate it in vectorized way.
