Enhancement Description
- One-line enhancement description : Consistent Reads from Cache
- Kubernetes Enhancement Proposal:
Kubernetes Get and List requests are guaranteed to be "consistent reads" if the
resourceVersion parameter is not provided. Consistent reads are served from
etcd using a "quorum read".
But often the watch cache contains sufficiently up-to-date data to serve the
read request, and could serve it far more efficiently.
This KEP proposes a mechanism to serve most reads from the watch cache
while still providing the same consistency guarantees as serving the
read from etcd.
All tasks done for beta
