[GitHub] [arrow] westonpace commented on issue #36139: [C++][Parquet] Allow Truncate min-max Statistics

   Does truncate discard?  Or does it write the truncated value and mark that it is truncated?
   
   For example, if I know the minimum value is "Hello W..." then I can reject the row group if there is a filter "value == 'blue'" even if I don't know the complete minimum value.
