> The latency is currently tracked separately from each operator subtask to
> each source subtask. The total number of latency metrics in the cluster is
> thus {{(# of sources) * (# of operators) * parallelism²}}, i.e. quadratic
> scaling.
> If we'd ignore the source subtask the scaling would be a lot more manageable.
