In-Process kube-apiserver Request Cost & Memory Optimization Study (BenchmarkRequestCost)

Purpose and Motivation

Profiling kube-apiserver memory consumption and per-request allocation churn in isolation is critical: isolated microbenchmarks exercise individual helper functions without realistic control plane wiring, while full end-to-end cluster tests introduce external network latency, node-agent background jitter, and non-deterministic garbage collection timing.

BenchmarkRequestCost (cost_test.go) provides a deterministic in-process kube-apiserver and embedded etcd3 integration harness designed to evaluate both per-request allocation churn (allocated bytes and object allocations per operation across JSON, CBOR, Protobuf, and Table formats) and server lifecycle heap metrics (server setup allocated bytes, retained heap in-use, retained runtime in-use, heap released, and heap span fragmentat

In-Process kube-apiserver Memory Integration Benchmark (TestAPIServerMemoryIntegration)

Purpose and Motivation

Profiling kube-apiserver memory consumption and allocation churn in isolation is challenging: microbenchmarks only exercise a single function at a time, while full cluster e2e tests introduce external network jitter, node-agent background noise, and non-deterministic garbage collection timing.

TestAPIServerMemoryIntegration (cmd/kube-apiserver/app/testing/apiserver_mem_bench_test.go) is a self-contained, deterministic in-process kube-apiserver + embedded etcd3 integration benchmark designed to measure both steady-state retained heap memory (pprof inuse_space, HeapInuse, HeapObjects, process RSS) and cumulative request allocation churn (pprof alloc_space, TotalAlloc, Mallocs, NumGC) with zero external dependencies.
