As this code is still very new, it has not been heavily optimized yet;
  while it is expected to _eventually_ have better performance than the
  iptables backend, very little performance testing has been done so far. ([#121046](https://github.com/kubernetes/kubernetes/pull/121046), [@danwinship](https://github.com/danwinship))

The steps below show how to use this notification target in `namespace` and `access` format.

### Step 1: Add Redis endpoint to MinIO

#### Audit Logging
* [alpha] Advanced Auditing enhances the Kubernetes API [audit logging](https://kubernetes.io/docs/tasks/debug/debug-cluster/audit/#log-backend) capabilities through a customizable policy, pluggable audit backends, and richer audit data.

#### Encryption at Rest

- Kube-apiserver: redirect responses are no longer returned from backends by default. Set `--aggregator-reject-forwarding-redirect=false` to continue forwarding redirect responses.

fronted by an L7 load balancer that already mitigates these http/2 attacks may choose not to enable the kube-apiserver mitigation to avoid disrupting load balancer → kube-apiserver connections if http/2 requests from multiple clients share the same backend connection. An API server on a private network may choose not to enable the kube-apiserver mitigation to prevent performance regressions for unauthenticated clients. Authenticated requests rely on the fix in golang.org/x/net v0.17.0 alone. https:...
