```C++
/// Set number of records to read per batch for the RecordBatchReader.
virtual void set_batch_size(int64_t batch_size) = 0;
```
@XinyuZeng Hi, after checking the code, the `set_batch_size` declares that
is for `RecordBatchReader`. And `ReadTable` or `ReadColumn` reads all data in a
file or some specific columns. So I think this might be expected. Would you
mind check that?
