    Description

      According to parquet format specification columns annotated as DECIMAL should use SIGNED comparator and statistics should be available. The sort order returned by org.apache.parquet.format.converter.ParquetMetadataConverter for DECIMAL is SortOrder.UNKNOWN which contradicts the specification and makes statistics for DECIMAL types unavailable.
