Expand description

Fixed-size operation-local cost and route attribution for one read.

Fields§

§total_local_instructions: u64

Complete local instructions observed by the outward read terminal.

§engine_local_instructions: u64

Local instructions observed inside the accepted dynamic execution path.

§response_decode_local_instructions: u64

Local instructions used to decode accepted rows into typed output. Dynamic reads report zero because their structural result is final.

§access_route: ReadAccessRoute

Coarse accepted access route selected by the planner.

§execution_route: ReadExecutionRoute

Physical route used by the executor.

§plan_cache: ReadPlanCacheOutcome

Cache outcome for the selected prepared plan.

§rows_scanned: u64

Physical keys or index entries visited while producing this page.

§rows_emitted: u64

Logical rows returned by this page.
