Significant CPU usage and possibly etcd usage when deploying this

[drewwells]

We noticed our ETCD storage usage doubled after doing a production release that included deploying reflector. Is there an architecture document for how this service watches for object changes and decided on API calls to make to kubeapi?

We have one configmap that rarely changes. This is the labels and annotations on it.

Here's the CPU and memory usage of reflector

❯ k -n reflector top po --containers                                                                                        🗑️  env-2a
