comphead opened a new issue, #2710:
URL: https://github.com/apache/datafusion-comet/issues/2710
### What is the problem the feature request solves?
Current plan for windows is
```
val df = sql("SELECT a, b, c, SUM(c) OVER (PARTITION BY a) as sum_c
FROM window_test")
+- !CometWindowExec [a#19, b#20, c#21, sum_c#25L], [sum(c#21)
windowspecdefinition(a#19, specifiedwindowframe(RowFrame,
unboundedpreceding$(), unboundedfollowing$())) AS sum_c#25L], [a#19]
+- CometSort [a#19, b#20, c#21], [a#19 ASC NULLS FIRST]
+- CometExchange hashpartitioning(a#19, 10), ENSURE_REQUIREMENTS,
CometNativeShuffle, [plan_id=87]
+- CometScan [native_iceberg_compat] parquet [a#19,b#20,c#21]
Batched: true, DataFilters: [], Format: CometParquet, Location:

```
