> 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.
