Description
Upstream officially marked the RV as comparable: https://github.com/kubernetes/enhancements/pull/5505
This allows us to extend the client to block reads until all relevant writes made it back into the cache.
Tasks
- v0.25
- Design: https://github.com/kubernetes-sigs/controller-runtime/pull/3473
- Initial implementation: https://github.com/kubernetes-sigs/controller-runtime/pull/3472
- v0.25.1
- Follow-ups: (more to be added once we merged the design)
- Optionally use https://github.com/kubernetes/kubernetes/pull/141688 (once merged)
- Consider evaluating shouldByPassCache and only wait if the client would use the cache
