Fields§

§physical_operator_id: PhysicalOperatorId§node_id: i64§partition_id: Option<usize>§name: String§open_time_us: u64§next_time_us: u64§close_time_us: u64§output_rows: u64§input_rows: u64

Rows consumed from the input (visible rows pulled from the child). Recorded only by operators whose feedback needs an input/output pair (currently Filter); zero means unmeasured, not empty input.

§exhausted: bool

Whether this operator instance ran to exhaustion (advance returned None). Operators starved by an upstream Limit or by early termination never exhaust; their partial row counts must not train the feedback loop.

§advance_count: u64

Number of chunks produced (advances). Used as the per-operator execution loop count in the feedback path.

§peak_memory: u64§peak_memory_bytes: u64§spilled_bytes: u64§spill_count: u64§spilled_rows: u64

Logical rows written to spill runs. Displayed next to the static spill_threshold config so PROFILE shows configured vs actual.
