   @maxburke  -- I fixed at least one bug in the rust parquet statistics 
generation ( PR was https://github.com/apache/arrow-rs/pull/643, which was 
first released in 5.2.0 it [appears 
according](https://github.com/apache/arrow-rs/blob/master/CHANGELOG.md#520-2021-08-12)
 to the changelog. 
   
   There may still be other bugs and if so I would love to help fix them
   
   > From a curiosity point of view, what should the min/max values be for 
string columns?
   
   In this case, I would expect the `min` value to be `"Incoming"` and the 
`max` value to be `"Two Way"` (namely the min and max values if the data was 
sorted via unicode codepoint)
