Struct TableCboStats 

pub struct TableCboStats {
    pub table: String,
    pub row_count: Option<u64>,
    pub ndv: Option<u64>,
    pub avg_row_bytes: Option<u64>,
    pub columns: Vec<ColumnCboStats>,
}

Catalog statistics the cost model needs for one table.

Fields

ndv: Option<u64>

avg_row_bytes: Option<u64>

columns: Vec<ColumnCboStats>

Column-level stats (empty unless ANALYZE ran with FOR COLUMNS).
