Struct JoinChoice 

pub struct JoinChoice {
    pub kind: JoinKind,
    pub table: String,
    pub strategy: Strategy,
    pub keys: usize,
    pub left_rows: usize,
    pub right_rows: usize,
    pub out_rows: usize,
}

What actually ran, per join, for EXPLAIN and for benchmark honesty.

Fields

kind: JoinKind

table: String

strategy: Strategy

keys: usize

How many equality key pairs the planner could prove usable. Zero means the hash path was not available at all.

left_rows: usize

right_rows: usize

out_rows: usize
