I started doing some work on this @izveigor but I am stucked in handling the non trivial case: [`main...edmondop:arrow-datafusion:issue-6981?`#diff-48cc9cf1bf](https://github.com/apache/arrow-datafusion/compare/main...edmondop:arrow-datafusion:issue-6981?#diff-48cc9cf1bfdb0214a9f625b384d1c4fd5967a9da61e8f22a5dc1c4c5800563b4R1511) I have the following newbie questions: - Which types I need to match against ? `(data_type, data_type)` ? - Should I implement a deduplication post a `concat_internal` or should I find a way to rewrite `concat_internal` that minimize allocations and keep a set to avoid adding element twice? - What when the type is not `DataType::List` ? -- This is an automated message from the Apache Git Service.
