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;
