> User reports that Trino Hudi connector might not project nested fields properly, e.g., the parent struct is read twice for multiple nested fields under the same struct.
> Trino Hudi connector does use similar projection logic as Hive connector in `HudiPageSourceProvider#createPageSource`.
> We need to further investigate this issue.
