### Is your feature request related to a problem or challenge? Currently DataFusion only supports non-deduplicating recursive CTEs (with `UNION ALL`). It would be great to support also deduplicating recursive CTEs. It is especially useful for transitive closures on arbitrary graphs including cycles. ### Describe the solution you'd like Update `RecursiveQueryExec` to support this case too. The boilerplate is already there but `RecursiveQueryExec` does not implement deduplication. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
