Light-City opened a new issue, #38633:
URL: https://github.com/apache/arrow/issues/38633
### Describe the bug, including details regarding any error messages,
version, and platform.
When limit k is greater than the actual table data and the table contains
Null/NaN, the data cannot be obtained and only non-empty results are available.
for example:
````
select * from test;
i | j
---+---
| 5
1 | 3
3 |
|
2 | 5
1 | 5
3 | 5
(7 rows)
```
When we execute order by limit k：
```
i | j
---+---
1 | 3
1 | 5
2 | 5
3 | 5
3 |
(5 rows)
```
Only 5 non-empty records will be returned.
Therefore, we support returning non-null and supporting the order of setting
Null for each SortKey.
