### Is your feature request related to a problem or challenge? In IOx we use columns statistics min and max in an optimizer rule however the statistics of column min and max are lost after going through filter (and may be many other operators). This ticket is to compute the Column statistics in a conservative way. ### Describe the solution you'd like Column min/max of filter will be the same but turns from `Exact` to `InExact`. When https://github.com/apache/arrow-datafusion/issues/8078 is implemented, The `InExact` in this case will become `Conservative` or the like While working on FilterExec, I will see if I can do the similarly for other operators ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
