描述

What would you like to be added?

Spin-off from https://github.com/etcd-io/etcd/issues/17529

Similar to https://github.com/etcd-io/etcd/pull/17680/files we should add more failpoints into watch and simulate:

  • slow watch sync
  • slow watch resynchronization
  • slow watch progress notify

etc

Why is this needed?

Prevent and detect other issues like https://github.com/etcd-io/etcd/issues/17529

研究方向
Study the existing failpoint implementation in etcd, particularly PR #17680 which added failpoints to other components. Identify the watch related files such as watchstore, watcher, etc. Understand the failpoint library used and how to inject delays. Then implement similar failpoints for slow watch sync, resynchronization, and progress notify.
