## Summary Preserve `null_count` when a column's min/max statistics exceed the metadata size limit. The size guard is needed for min/max values, but `null_count` is a compact independent statistic and remains useful to readers. This keeps the null count available without reintroducing oversized min/max metadata. ## Changes - Emit `null_count` before applying the min/max size limit. - Keep nan count and min/max omission behavior unchanged for oversized statistics. - Extend the binary statistics round-trip test to cover the preserved null count. ## Testing - `./mvnw -pl parquet-hadoop -am -DskipITs -Dtest=TestParquetMetadataConverter -Dsurefire.failIfNoSpecifiedTests=false test` - `./mvnw -pl parquet-hadoop -am -DskipTests spotless:check` - `git diff --check` All passed. ## Notes - No competing open PR for #3574 was present during the final duplicate check. - AI assistance was used during development; the submitter reviewed the complete diff and is responsible for the change.
