### Is your feature request related to a problem or challenge? If you have a datasource that reports a sum statistic then merging statistics for a file group is considerably slower when compared to cases without sum statistic. Profiling reveals it's mostly due to `Precision<ScalarValue>::add` doing a lot of extra work. ### Describe the solution you'd like Ideally we'd transpose the stats aggregation and aggregate them column wise instead of column group wise ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
