This substantially reduces the number of API calls made by the endpoint controller. Currently the controller makes an API call per endpoint for each service that is synced. When the 30s resync is triggered, this results in an API call for every single endpoint in the cluster. This quickly exceeds the default qps/burst limit of 20/30 even in small clusters, leading to delays in endpoint updates. This change modifies the controller to use the endpoint informer cache for all endpoint GETs. This means we only make API calls for changes in endpoints. As a result, qps only depends on the pod activity in the cluster, rather than the number of services. |
