andygrove opened a new issue, #1275:
URL: https://github.com/apache/datafusion-comet/issues/1275
### What is the problem the feature request solves?
Comet is 4x slower than Spark for the following query:
```python
spark.read.parquet("/mnt/bigdata/tpcds/sf100/store_sales.parquet") \
.repartition("ss_item_sk") \
.dropDuplicates(["ss_item_sk", "ss_quantity"]) \
.write.parquet("output.parquet")
```
If I remove the `dropDuplicates` call, I see similar performance between
Comet and Spark.
