-This depends on the CPU metrics available on the deployment, eg.:
-`kube_pod_container_resource_limits{resource="cpu", unit="core"}` for
-Kubernetes. Let's call it `available_cores`. The idea here is to have an upper
-bound of the number of available cores, and the maximum expected ingestion rate
-considered safe, let's call it `safe_rate`, per core. This should trigger
-increase of resources/ instances (or raise an alert as appropriate) whenever
-`(actual_rate/available_cores) < safe_rate`.

-The `safe_rate` depends on the specific configuration being used. // TODO:
-Provide reference `safe_rate` for a few selected configurations.
