> The case when and if statement execution for Hive vectorization is not
> optimal, which all the conditional and else expressions are evaluated for
> current implementation. The optimized approach is to update the selected
> array of batch parameter after the conditional expression is executed. Then
> the else expression will only do the selected rows instead of all.
