> Currently, in C++ version of orc. We can only select by filed id or field name. This works fine when data structure is flat such as struct<int1:int, s1:string, list1:array<int>>. But when we have a nested structure, struct<int1:int, struct1:struct<int2:int, long2:long>>. We still can only select the field of int1 and struct1. We can not directly select long2.
> We can select long2 by its column id. This can be achieved by updating include function in ReaderOptions.
