# Witness Protocol Feature - Detailed Design Document

## 1. Overview

The SMB Witness Protocol enables rapid notification of resource changes in a clustered file server environment. It provides fast failover capabilities by allowing clients to register for notifications about server node availability, share movement, and other critical cluster events.

## 2. Protocol Specification Reference

- Resolved a performance regression in default 1.31+ configurations, related to the `ConsistentListFromCache` feature, where rapid create/update API requests across different namespaces encounter increased latency. ([#130113](https://github.com/kubernetes/kubernetes/pull/130113), [@AwesomePatrol](https://github.com/AwesomePatrol))

failures and now perform a more rigorous reconciliation to ensure static pods (especially those that use fixed UIDs) are restarted.  As a side effect of these changes static pods will be restarted with lower latency than before (2s vs 4s, on average) and rapid updates to pod configuration should take effect sooner.
  
  A new metric `kubelet_known_pods` has been added at ALPHA stability to report the number of pods a Kubelet is tracking in a number of internal states.  Operators may use the metrics...

- Fixes kubectl to apply all validly built objects, instead of stopping on error. ([#89864](https://github.com/kubernetes/kubernetes/pull/89864), [@seans3](https://github.com/seans3)) [SIG CLI and Testing]

- Fixes conversion error for HorizontalPodAutoscaler objects with invalid annotations ([#89963](https://github.com/kubernetes/kubernetes/pull/89963), [@liggitt](https://github.com/liggitt)) [SIG Autoscaling]
- Fixes kubectl to apply all validly built objects, instead of stopping on error. ([#89848](https://github.com/kubernetes/kubernetes/pull/89848), [@seans3](https://github.com/seans3)) [SIG CLI and Testing]

#### DaemonSet
* [beta] DaemonSet supports history and rollback. See [Performing a Rollback on a DaemonSet](https://kubernetes.io/docs/tasks/manage-daemon/rollback-daemon-set/).

- Print go stack traces at -v=4 and not -v=2 ([#94663](https://github.com/kubernetes/kubernetes/pull/94663), [@soltysh](https://github.com/soltysh)) [SIG CLI]
- Recreate EndpointSlices on rapid Service creation. ([#94730](https://github.com/kubernetes/kubernetes/pull/94730), [@robscott](https://github.com/robscott))
