> Currently DATE/TIME/TIMESTAMP have internal representation. Such as Date is
> represented as Int internal.
> This feature may improve performance processing DATE/TIME/TIMESTAMP data.
> But I found there is a LIMITATION: internal representation exists only within
> one operator.
> We transfer DATE/TIME/TIMESTAMP objects between operators.
> I think we could treat DATE/TIME/TIMESTAMP as internal representation in the
> whole job, and cast them to java.sql.* as needed(UDF/UDTF/OUTPUT)
