Review Comment:
   warning: use auto when initializing with a cast to avoid duplicating the 
type name [modernize-use-auto]
   
   ```suggestion
       auto* cur_batch = 
dynamic_cast<orc::TimestampVectorBatch*>(orc_col_batch);
   ```

Review Comment:
   warning: 1000 is a magic number; consider replacing it with a named constant 
[readability-magic-numbers]
   ```cpp
           cur_batch->nanoseconds[row_id] = datetime_val.microsecond() * 1000;
                                                                         ^
   ```
