[][src]Struct transform::join_implementation::JoinImplementation

pub struct JoinImplementation;

Determines the join implementation for join operators.

Implementations

impl JoinImplementation[src]

pub fn action_recursive(
    &self,
    relation: &mut RelationExpr,
    arranged: &mut HashMap<Id, Vec<Vec<ScalarExpr>>>
)
[src]

Pre-order visitor for each RelationExpr to find join operators.

This method accumulates state about let-bound arrangements, so that join operators can more accurately assess their available arrangements.

pub fn action(
    &self,
    relation: &mut RelationExpr,
    indexes: &HashMap<Id, Vec<Vec<ScalarExpr>>>
)
[src]

Determines the join implementation for join operators.
