Deep Dive: Scalability SIG

on YouTube ↗34m

" summary

Scalability SIG lays out concrete practices: public clusterloader and kubemark test suites run as PR and postsubmit jobs (100‑ and 500‑node PR tests, a 5,000‑node postsubmit), collection of CPU/memory profiles from all control‑plane components, and a declarative load generator for repeatable scenarios. Recent wins include node heartbeat reduction, kubelet switching from polling to watches for Secrets, a revised events API, scheduler node‑subset ranking, and IPVS GA; regressions still arrive from Go and kernel changes and tests are expanding to catch them.
