Describe the bug
Spark is trying to improve iceberg/delta lake query performance where the data may have already been partitioned properly that a shuffle is not needed for an order by operation. I am not sure if this is going to impact us directly or not. I don't think we support iceberg on spark 4.0.0 yet. But we do support delta lake so it might be related in some ways. Hard to tell.
