comphead opened a new issue, #10491:
URL: https://github.com/apache/datafusion/issues/10491
I'm not able to run such test just because of other SMJ issue
not related to this PR:
If the join filter is set and for the same streaming index there are
matching rows more or equal to a batch size then the query just stuck. Likely
the problem is in polling state and it can be easily reproduced on main branch.
```
#[tokio::test]
async fn test_11() -> Result<()> {
let ctx: SessionContext = SessionContext::new();
let sql = "set datafusion.optimizer.prefer_hash_join = false;";
let _ = ctx.sql(sql).await?.collect().await?;
let sql = "set datafusion.execution.batch_size = 1";
let _ = ctx.sql(sql).await?.collect().await?;
let sql = "
select * from (
with
t1 as (
select 12 a, 12 b
),
t2 as (
select 12 a, 12 b
)
select t1.* from t1 join t2 on t1.a = t2.b where t1.a > t2.b
) order by 1, 2;
";
let actual = ctx.sql(sql).await?.collect().await?;
Ok(())
}
```
I'll file a separate issue for this one, but perhaps we can go with this PR
because potential problem you talking about cannot ever be hit because of the
issue above
