   also, I guess `$ReadTable()` could either be simplified to only use column 
indices (as in the C++ function)
   
   ```cpp
   virtual ::arrow::Status ReadTable(const std::vector<int>& column_indices,
                                       std::shared_ptr<::arrow::Table>* out) = 
0;
   ```
   
   or maybe have some arguments to turn off potentially expensive tidyselect 
logic, that has to retrieve the schema ...
