**Use case**

Like `date_time_input_format = 'best_effort'` but with disambiguation to American mm/dd/yyyy style.

bool import_nested = false;
        bool allow_missing_columns = false;
        int64_t row_batch_size = 100'000;
    } orc;
    
    
    enum class EnumComparingMode
    {
        BY_NAMES, 
        BY_NAMES_CASE_INSENSITIVE, 
        BY_VALUES, 
    };
    struct
    {
        EnumComparingMode enum_comparing_mode = EnumComparingMode::BY_VALUES;
    } capn_proto;
    enum class MsgPackUUIDRepresentation
    {
        STR, 
        BIN, 
        EXT, 
    };
    struct
    {
        UInt64 number_of_columns = 0;
        MsgPackUUIDRepresentation output_uuid_representation = MsgPackUUIDRepresentation::EXT;
    } msgpack;
};
}
