niebayes opened a new issue, #18933: URL: https://github.com/apache/datafusion/issues/18933
There generally has requirements for renaming, appending, removing a column from the input plan. If the input plan has an equivalence properties, it should be preserved as much as possible when the schema is altered. However, the current `EquivalenceProperties::new_with_schema` implementation requires the new schema and the original schema are aligned. Specifically, the number of columns and column positions should be consistent. I wonder if we can remove the align requirement. -- This is an automated message from the Apache Git Service.
