-----------------------------------
Summary: Statistics is not available for DECIMAL types
Key: PARQUET-1322
URL: https://issues.apache.org/jira/browse/PARQUET-1322
Project: Parquet
Issue Type: Bug
Reporter: Vlad Rozov
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.
