viirya opened a new issue, #974: URL: https://github.com/apache/datafusion-comet/issues/974
### Describe the bug This is related to #973. After applying the fix, the test we run locally with Iceberg table with deleted rows fails on incorrect query result. It is because Iceberg doesn't actually delete the rows from the arrays but stores a row mapping in arrays that is used to skip deleted rows when iterating rows in a columnar batch. However, once we export the underlying Arrow record batch of a columnar batch to native side. The record batch is totally physical without the logical row mapping info. That's said, the deleted rows will occur in the query. When exporting a record batch from Iceberg record batch, we need to export the row mapping together. ### Steps to reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
