> See this code fragment in BaseQueryPlan.iterator(...):
> {code}
> // wrap the iterator so we start/end tracing as we expect
> TraceScope scope =
> Tracing.startNewSpan(context.getConnection(), "Creating basic query for
"
> + getPlanSteps(iterator));
> return (scope.getSpan() != null) ? new TracingIterator(scope, iterator) : iterator;
> {code}
> This will get the plan steps for each and every call to iterator, whether we're tracing
or not.
