Struct PageStat 

pub struct PageStat {
    pub first_row_id: u64,
    pub last_row_id: u64,
    pub null_count: u64,
    pub row_count: u32,
    pub min: Option<Vec<u8>>,
    pub max: Option<Vec<u8>>,
    pub offset: u64,
    pub compressed_len: u32,
    pub uncompressed_len: u32,
}

Per-page statistics enabling file/page-level pruning (analogous to Parquet’s page index, but always present and tighter). Serialized in the run’s column directory.
