etcd 3.7 lands in perf-tests, watch cache gains Limit support
By RepoJournal · Filed · About Kubernetes · Composed from the cited sources · methodology
Kubernetes' scalability and apiserver work moved forward on three fronts today: perf-tests upgraded to etcd 3.7, the watch cache gained Limit support, and the webhook authorizer learned conditions.
Update etcd to 3.7 and fix measurements kubernetes/perf-tests
Marek Siarkowicz's change moves the perf-tests harness onto etcd 3.7 and corrects how measurements are taken, so scalability numbers are comparable against the new storage backend. Benchmarks run before this landing should not be compared with runs after it.
Merge pull request #142877 from serathius/watchcache-repro-94002 kubernetes/apiserver
The watch cache now implements Limit, shipped alongside a reproduction for watch cache issue #94002. This is the scaffolding for fixing the underlying bug, not the fix itself.
Merge pull request #137633 from luxas/impl-conditional-authz-3 kubernetes/apiserver
Part 3 of the Conditional Authz series makes the webhook authorizer support conditions, extending the authorizer API beyond plain allow/deny decisions. Anyone implementing or consuming webhook authorization should watch where this lands before it reaches a stable API.
Merge pull request #18842 from Jefftree/5k-etcd-progress-notify kubernetes/kops
The kops e2e scalability suite now configures a watch progress notify interval for scale clusters, and the same alignment landed in the write-throughput benchmark so its kind config matches the GCE kube-up scalability flags used in CI.
Merge pull request #138361 from kairosci/fix/replace-deprecated-wait-pollimmediateuntil kubernetes/endpointslice
client-go's tools/cache tests replaced the deprecated wait.Poll with PollImmediateUntil, a mechanical cleanup of test code published across the split repositories. The website picked up the AI Conformance spotlight interview and a Korean translation refresh.
