Closing: this re-lands #3575, which was reverted in #3688 because Iceberg `ParquetMetrics` still treats `Statistics.isEmpty()` as all-or-nothing. Mixed row groups (small strings with min/max + large strings over `MAX_STATS_SIZE`) would then publish incomplete file-level bounds. Iceberg needs to keep null counts iff every chunk `isNumNullsSet()` and **drop file-level bounds** when a chunk has values but `!hasNonNullValue()`, before this parquet-java split is safe. Sorry for the noise — #3574 remains valid once that consumer contract is evolved. -- This is an automated message from the Apache Git Service.
