URL: https://github.com/apache/datafusion/pull/25579
The fix prevents one aggregate’s filter from discarding rows that another
aggregate still needs in dynamic filters. Example:
Query: `MIN(a), MAX(a), MIN(b), MAX(b)`
```
First batch: (1, NULL), (8, NULL)
|
v
a has bounds [1, 8]
b has no bounds yet
|
+---------+----------+
| |
Before After
| |
a < 1 OR a > 8 filter = true
| |
v v
Next batch: (2, 5), (3, 7)
| |
Both rows rejected Both rows accepted
| |
v v
Result: Now b has bounds [5, 7]
1 8 NULL NULL |
v
Filtering can start:
a < 1 OR a > 8
OR b < 5 OR b > 7
|
v
Correct result: 1 8 5 7
```
