## What - Support `write.parquet.stats-enabled.column.<name>` for data files. ## Why - Let users disable statistics for selected columns. This can reduce scan pruning. ## Implementation - Keep statistics enabled by default and map Iceberg field names to Parquet paths. - Follow [Iceberg Java](https://github.com/apache/iceberg/blob/014b3ce5ffbf7c1c51dabb144f4d94e45addcd88/parquet/src/main/java/org/apache/iceberg/parquet/Parquet.java#L361-L376), including its [delete-file behavior](https://github.com/apache/iceberg/blob/014b3ce5ffbf7c1c51dabb144f4d94e45addcd88/parquet/src/main/java/org/apache/iceberg/parquet/Parquet.java#L843-L863). - The [Parquet spec](https://github.com/apache/parquet-format/blob/ec90dd4661ff1c4d77f06b5b5232c5aedf68ffc5/src/main/thrift/parquet.thrift#L955-L959) makes column statistics optional. The [Iceberg spec](https://iceberg.apache.org/spec/#field-level-metrics-and-statistics) describes file metrics used for filtering. -- This is an automated message from the Apache Git Service.
