### What changes were proposed in this pull request? Remove unnecessary physical projection added to ensure rows are `UnsafeRow` when the DSv2 scan is columnar. This is not needed because conversions are automatically added to convert from columnar operators to `UnsafeRow` when the next operator does not support columnar execution. ### Why are the changes needed? Removes an extra projection and copy. ### Does this PR introduce any user-facing change? No. ### How was this patch tested? Existing tests. Closes #25586 from rdblue/SPARK-28878-remove-dsv2-project-with-columnar. Authored-by: Ryan Blue <blue@apache.org> Signed-off-by: Wenchen Fan <wenchen@databricks.com> |
