Per-VPA target percentiles, WatchList benchmarks in the request path
By RepoJournal · Filed · About Kubernetes · Composed from the cited sources · methodology
The day's work spans VPA configuration surface and the measurement plumbing for WatchList, the API mechanism the project is benchmarking before it can replace the watch cache.
AEP-9970: per-VPA target percentiles kubernetes/autoscaler
The AEP adds targetCPUPercentile and targetMemoryPercentile to ContainerResourcePolicy, so the percentile behind a VPA's CPU and memory recommendations becomes a per-object setting rather than a global flag. It extends AEP-8026's per-VPA configuration mechanism to the target fields; bound percentiles are explicitly left as future work.
add watch-list mode to request benchmark kubernetes/perf-tests
The request benchmark gains an optional HTTP WatchList mode, which measures WatchList latency while ruling out client-side typed-object decoding as a source of overhead. The companion presubmit job creates pull-kubernetes-benchmark-watchlist-proto-http to exercise the WatchList HTTP list path in CI.
Migrate 5,000-node scale tests to c4d-standard-96 kubernetes/test-infra
All 5,000-node scale test control planes move from c4-standard-96 to c4d-standard-96 after the upstream jobs showed severe run-to-run variance from host processor differences in the provider pool, which was obscuring genuine performance regressions. The experiment is done and the backing revert is included.
Merge pull request #142638 from Jefftree/event-handler-name-portability kubernetes/client-go
TestNameForHandler in client-go/tools/cache now derives the package path dynamically instead of hardcoding it. Small, but it removes a portability break for anyone running that test outside its original tree.
Merge pull request #10079 from locker95/docs/vpa-requests-limits-faq kubernetes/autoscaler
Elsewhere: the autoscaler FAQ now documents requests-versus-limits behavior, DRANET 1.5.0 images are promoted to the prod registry, and node-ipam-controller switches to squash merges.
