Struct ProfileMetrics 

pub struct ProfileMetrics {
    pub total_elapsed_ns: u64,
    pub total_rows: u64,
    pub mutated: bool,
    pub per_operator: BTreeMap<usize, OperatorMetrics>,
}

Coarse-grained per-query runtime metrics. v1 reports totals, not per-operator timings; per-operator instrumentation is reserved for a future phase that will not change the public surface.

Fields

total_elapsed_ns: u64

Wall-clock time spent inside the executor for this query.

total_rows: u64

Number of rows produced before result-format projection.

mutated: bool

Whether at least one mutating operator ran.

per_operator: BTreeMap<usize, OperatorMetrics>

Reserved for future operator-level metrics. Present today as an empty map so consumers can pattern-match on the field without breaking when v2 starts populating it.
