# Which issue does this PR close? No linked issue. # Rationale for this change Decimal precision 1 was incorrectly mapped to Parquet INT64 because the INT32 physical-type range used an exclusive lower bound, even though precisions 1 through 9 fit in INT32. This corrects the generated Parquet physical schema so a precision-one decimal is written as INT32. # What changes are included in this PR? A one-line boundary correction in the Arrow-to-Parquet decimal mapping (exclusive `> 1` lower bound changed to inclusive `>= 1`), plus a focused regression test. # Are these changes tested? Yes. A regression test was added verifying that a precision-one decimal maps to the Parquet INT32 physical type. # Are there any significant user-facing changes? No significant API or compatibility changes. This corrects the generated Parquet physical schema for precision-one decimals. -- This is an automated message from the Apache Git Service.
