### What The heaviest requests we serve are the register and metrics POSTs from our SDKs/clients. This PR adds ratelimiting to /api/client/register, /api/client/metrics, /api/frontend/register and /api/frontend/metrics with a default set to 6000 requests per minute (or 100 rps) for each of the endpoints. It will be overrideable by the environment variables documented. ### Points of discussion @kwasniew already suggested using featuretoggles with variants to control the rate per clientId. I struggled to see if we could dynamically update the middleware after initialisation, so this attempt will need a restart of the pod to update the request limit. |
