   I tried inspecting the columnChunkMetadata as per the Parquet Thrift documentation: https://github.com/apache/parquet-format/blob/master/Encryption.md#43-key-metadata
   
   and I do not see the keyValueMetadata value:
   ```
   <pyarrow._parquet.ColumnChunkMetaData object at 0x1122fbe20>
     file_offset: 114
     file_path: 
     physical_type: INT64
     num_values: 3
     path_in_schema: a
     is_stats_set: True
     statistics:
       <pyarrow._parquet.Statistics object at 0x112314040>
         has_min_max: True
         min: 1
         max: 3
         null_count: 0
         distinct_count: 0
