Rationale for this change
The
StatisticsAsScalarsfunction, which allows converting Parquet statistics (min/max values) for a given logical type into Arrow scalars, did not support DECIMAL columns with physical type INT32 or INT64.Are these changes tested?
Yes, by expanded unit test.
Are there any user-facing changes?
No, just a bug fix.
