> The parquet-format project introduced a new UUID logical type in version 2.4:
> [https://github.com/apache/parquet-format/blob/master/CHANGES.md]
> This would be a useful type to have available in some circumstances, but it currently isn't supported in the parquet-mr library. Hopefully this feature can be implemented at some point.
