### Is your feature request related to a problem or challenge? We lose opportunities for many optimizations due to not outputting these statistics ### Describe the solution you'd like In project and similar operators, when encountering a constant column, we should be able to output statistics about it, for example min and max values should be the same values, the memory usage should be constant etc, such info can later be used to optimize sorts and so on. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
