Enum AccessPathPlan 

pub enum AccessPathPlan {
    Row,
    OperatorTree {
        score_limit_pushdown: bool,
    },
    Hybrid,
}

Cross-paradigm access decision made after the relational and scalar portions of a query block have both been lowered.

Variants

Row

Ordinary row-source execution.

OperatorTree

Use the shared document-support/operator algebra for the block predicate.

Fields

score_limit_pushdown: bool

The relational ORDER BY/OFFSET/LIMIT can be pushed into the retrieval function before row materialization.

Hybrid

Split a mixed predicate into posting-list candidates followed by row-level residual evaluation.
