Struct RelationalOperatorCardinalityProfile 

pub struct RelationalOperatorCardinalityProfile {
    pub operator_id: RelationalOperatorId,
    pub operator: RelationalOperatorKind,
    pub table: String,
    pub access_path: RelationalAccessPathDescriptor,
    pub estimated_rows: usize,
    pub actual_rows: Option<usize>,
    pub fully_consumed: bool,
}

Estimated and observed output cardinality at one relational operator boundary.

Fields

operator_id: RelationalOperatorId

operator: RelationalOperatorKind

table: String

access_path: RelationalAccessPathDescriptor

The physical access path executed by this operator.

estimated_rows: usize

actual_rows: Option<usize>

None means execution never invoked the access pipeline. Some(0) means the operator ran and produced no rows.

fully_consumed: bool

True only when execution observed the end of the operator pipeline.
