Exception request for KEP-3386: Kubelet Evented PLEG for Better Performance

[Harshal Patil]

Enhancement name: Kubelet Evented PLEG for Better Performance

Enhancement status (alpha/beta/stable): alpha

SIG: sig-node

k/enhancements repo issue #:
https://github.com/kubernetes/enhancements/issues/3386

PR #’s: https://github.com/kubernetes/kubernetes/pull/111642 and
https://github.com/kubernetes/kubernetes/pull/111384

Additional time needed (in days): 6

Reason this enhancement is critical for this milestone: This
enhancement implements critical performance improvement that is
essential for achieving high pod density on the node.

Risks from adding code late: (to k8s stability, testing, etc.): None.
The implementation is feature gated, so there is no risk for the
existing Generic PLEG implementation.

Risks from cutting enhancement: (partial implementation, critical
customer usecase, etc.): Users with high resource usage due to high
pod density would stand to benefit with this feature. We have the CRI
API changes already merged,
https://github.com/kubernetes/kubernetes/pull/111642. The only
standing issue was the non-blocking job
`pull-kubernetes-e2e-gce-alpha-features` failing, but that has been
fixed now and all CI jobs on the main PR,
https://github.com/kubernetes/kubernetes/pull/111384, are green now.

Thanks,
