### Describe the bug When looking at aggregation modes I found that the single aggregation mode requires inputs to be partitioned already, but it doesn't. As we're only using the `Single` mode in an optimizer rule, it isn't too much of a problem ATM, but would be if we start using the mode more often. ### To Reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
