### Is your feature request related to a problem or challenge? Per https://github.com/apache/datafusion/pull/21240#discussion_r3065275637 , if the same subquery (identical SQL text) appears multiple times in a query, it will be planned and evaluated multiple times. In principle it should be fine to evaluate it only once, provided the subquery doesn't contain any volatile functions (e.g., `random()`). ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
