…e#38985)

## Proposed changes

Before：
```
select l_quantity from lineitem order by l_quantity limit 10000020;
+--------------+
| ReturnedRows |
+--------------+
| 10000020     |
+--------------+
1 row in set (2 min 24.42 sec)

```

after:
```
mysql [tpch]>select l_quantity from lineitem order by l_quantity limit 10000020;
+--------------+
| ReturnedRows |
+--------------+
| 10000020     |
+--------------+
1 row in set (28.42 sec)
```
