I think, changing implementation below
```
fn with_new_children(
self: Arc<Self>,
children: Vec<Arc<dyn ExecutionPlan>>,
) -> DataFusionResult<Arc<dyn ExecutionPlan>> {
ExecutionPlan::with_new_children(self.parquet_scan.clone(), children)
}
```
to something like
```
fn with_new_children(
self: Arc<Self>,
children: Vec<Arc<dyn ExecutionPlan>>,
) -> Result<Arc<dyn ExecutionPlan>> {
// Make sure to received single child
// It should be updated new parquet_scan.
assert_eq!(children.len(), 1);
Arc::new(DeltaScan {
table_uri: self.table_uri.clone(),
config: self.config.clone(),
parquet_scan: children[0].clone(),
logical_schema: self.logical_schema.clone(),
})
// ExecutionPlan::with_new_children(self.parquet_scan.clone(),
children)
}
```
might solve the problem (Just brainstorming, I didn't try it). I am not
sure, what `ExecutionPlan::with_new_children(self.parquet_scan.clone(),
children)` does. However, this line might be the root cause of the problem.
