Suggested change
| // In current implementations, `num_values` is the `num_values` field in the | |
| // data page header, which may greater than the number of values in the data | |
| // buffer. | |
| // `num_values` comes from the data page header, and may be greater than the number of | |
| // physical values in the data buffer if there are some omitted (null) values. | |
| // `len`, on the other hand, is the size in bytes of the data buffer and | |
| // directly relates to the number of physical values. |
