To create a reproduce test its needed to run a test in debug mode
```
async fn test_anti_join_1k_filtered() {
// NLJ vs HJ gives wrong result
// Tracked in https://github.com/apache/datafusion/issues/11537
for i in 0..1000 {
JoinFuzzTestCase::new(
make_staggered_batches(1000),
make_staggered_batches(1000),
JoinType::LeftAnti,
Some(Box::new(col_lt_col_filter)),
)
.run_test(&[JoinTestType::HjSmj], true)
.await
}
}
```
the test creates a dump of data locally to the disk. for example
`fuzz_test_debug/batch_size_7`
The test below is a reproduce case(just set the paths) which step 1 outputs
```
#[tokio::test]
async fn test1() {
let left: Vec<RecordBatch> =
JoinFuzzTestCase::load_partitioned_batches_from_parquet(
"fuzz_test_debug/batch_size_7/input1",
)
.await
.unwrap();
let right: Vec<RecordBatch> =
JoinFuzzTestCase::load_partitioned_batches_from_parquet(
"fuzz_test_debug/batch_size_7/input2",
)
.await
.unwrap();
JoinFuzzTestCase::new(
left,
right,
JoinType::LeftAnti,
Some(Box::new(col_lt_col_filter)),
)
.run_test(&[JoinTestType::HjSmj], false)
.await;
}
```
