> The [current reader code](https://github.com/apache/arrow-rs/blob/1b8cd9ace2e746a073ee7204db5d0d0cfec67d31/parquet/src/file/metadata/reader.rs#L1046C20-L1055C22) for interpreting sort orders, does not appear to push back any elements into the Vec if the sort order does not match TYPEORDER. I think the generated thrift parser would already have returned an error [here](https://github.com/apache/arrow-rs/blob/9c0cb9a56f0099e7d39087826d7e409ce0f1bf5f/parquet/src/format.rs#L5038) for an unknown `ColumnOrder`. I don't think it should panic though. What behavior would we want from a thrift parser? To avoid this problem, each generated enum would need to have some `UNKNOWN` / `UNSUPPORTED` variant. For `ColumnOrder` we could just ignore the statistics in that case, but I'm not sure whether in general this would just move the error to another place in the code. -- This is an automated message from the Apache Git Service.
