Marek Siarkowicz 80746a8efd Disable estimating resource size for resources with watch cache disabled 
Listing all keys from etcd turned out to be too expensive, negativly
impacting events POST latency. Events resource is the only resource that
by default has watch cache disabled and which includes very
large number of small objects making it very costly to list keys.

Expected impact:
* No apiserver_resource_size_estimate_bytes metric for events.
* APF overestimating LIST request cost to events. Fallback assumes
  object size of 1.5MB, meaning LIST events will always get maxSeats

apiserver

Generic library for building a Kubernetes aggregated API server.

Purpose

This library contains code to create Kubernetes aggregation server complete with delegated authentication and authorization, kubectl compatible discovery information, optional admission chain, and versioned types. It's first consumers are k8s.io/kubernetes, k8s.io/kube-aggregator, and github.com/kubernetes-incubator/service-catalog.

Compatibility

There are NO compatibility guarantees for this repository, yet. It is in direct support of Kubernetes, so branches will track Kubernetes and be compatible with that repo. As we more cleanly separate the layers, we will review the compatibility guarantee. We have a goal to make this easier to use in the future.

Where does it come from?

apiserver is synced from https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/apiserver. Code changes are made in that location, merged into k8s.io/kubernetes and later synced here.

Things you should NOT do

  1. Directly modify any files under pkg in this repo. Those are driven from k8s.io/kubernetes/staging/src/k8s.io/apiserver.
  2. Expect compatibility. This repo is changing quickly in direct support of Kubernetes and the API isn't yet stable enough for API guarantees.
