The issue likely comes from https://github.com/apache/datafusion/blob/408e1e4e2c46d673a067e05f3e363a6f51e641c4/datafusion/datasource-parquet/src/metadata.rs#L247-L322 When one column has statistics, the code processes all columns’ statistics. For columns with statistics disabled, their stats are recorded as `NULL` instead of being marked as `Absent`, which causes incorrect predicate pruning on `IS NULL` / `IS NOT NULL` filters. -- This is an automated message from the Apache Git Service.
