lgbo-ustc opened a new issue, #11451:
URL: https://github.com/apache/incubator-gluten/issues/11451
### Backend
CH (ClickHouse)
### Bug description
[Expected behavior] and [actual behavior].
We have a query as following
```sql
select * from t1 left join (select * from t2 where day='2026-01-01')
```
The partition `2026-01-01` in `t2` exists, but has no data. `t1` has one
row. The query result has one row for `vanilla`, but is empty for `gluten(ch)`.
The physical plan for gluten is
```
+- == Final Plan ==
CHNativeColumnarToRow (13)
+- ^ ProjectExecTransformer (11)
+- ^ CHBroadcastNestedLoopJoinExecTransformer LeftOuter BuildLeft (10)
:- ^ InputIteratorTransformer (6)
: +- BroadcastQueryStage (4), Statistics(sizeInBytes=27.0 B,
rowCount=1)
: +- ColumnarBroadcastExchange (3)
: +- ^ NativeScan hive t1(1)
+- ^ ProjectExecTransformer (9)
+- ^ FilterExecTransformer (8)
+- ^ NativeScan hive t2(7)
```
the physical plan for vanilla is
```
+- == Final Plan ==
* Project (2)
+- Scan hive t1(1)
```
