Adds a stress testing framework for ClickHouse Keeper under `tests/stress/keeper/`, wired into CI (PR gate + nightly workflows). Key components: - Workloads: `keeper_bench.py` runner with YAML-defined workload profiles (`prod_mix.yaml`, `read_requests.yaml`, `write_requests.yaml`, etc.) - Scenarios: `core_no_faults.yaml` and `core_faults.yaml` with netem-based network fault injection (latency, jitter, packet loss) - Fault framework: `faults/network.py` (netem), `faults/base.py` (step dispatcher with `kind: parallel` support) - Metrics: `MetricsSampler` collects keeper stats, `sink.py` writes JSONL, ingested into CIDB via `ingest_keeper_metrics.py` post-hook - Gates: scenario pass/fail conditions based on RPS, p99 latency, error rate - Grafana dashboards for run details, 1vs1 comparison, historical progression CI integration: - PR job: 3 no-fault scenarios (prod-mix, read-multi, write-multi), ARM_LARGE, 15 min each, runs when `src/Coordination/` or stress test files change - Nightly (no-faults): all no-fault scenarios, default + rocks backends, ARM_LARGE - Nightly (faults): all fault scenarios, default + rocks backends, ARM_LARGE - Single `keeper_stress_job` config; mode detected via `Info().pr_number` and `Info().workflow_name` inside the job script Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
