commit abedc3f068092c0e61b7eb795e204b51d0177195 Author: Hongtao Gao <[email protected]> AuthorDate: Sat May 9 15:05:11 2026 +0000 feat(soak): G5d soak harness — docker-compose + soak-driver + runbook Land the Phase A harness for the G5d soak gate. Local-only, no kind/k8s, no cloud — sized for a 31 GB no-swap dev box. Architecture: sequential, single-stack. Phase 0 boots vec-off, seeds a deterministic group + measure (soak/soak_metric), records a baseline over the seed window, snapshots the data dir, tears down. Phase 1 boots vec-on with the restored snapshot, drives synthetic + OAP traffic for SOAK_HOURS, captures pprof every PPROF_INTERVAL_MIN, replays the catalog every PARITY_INTERVAL_MIN to diff against the baseline, and tails BanyanDB logs for MemoryTracker exhaustion. The parity catalog is time-bounded to the pre-snapshot window so OAP's ongoing writes do not pollute the diff. Files: test/soak/docker-compose.soak.yaml (235 LOC) — overlay over the quick-start. BanyanDB built from local source so the vectorized branch is exercised. Every container has explicit memory + cpus limits totalling ~6.5 GB. Banyandb runs as host UID/GID (${SOAK_UID}:${SOAK_GID}) so the bind-mounted /data is readable from the host shell for snapshot/restore. Default root paths are overridden to /data so the bind mount actually contains the data (--measure-root-path, --stream-root-path, --property-root-path, --trace-root-path, --schema-server-root-path). test/soak/Dockerfile.banyand (52 LOC) — multi-stage build of /banyand from this branch's source. cmd/soak-driver/main.go (649 LOC) — Go CLI with four subcommands: seed-fixture (creates Group + Measure + writes N deterministic rows, polls until visible — handles the 5s flush timeout), record-baseline (queries the catalog and persists proto-marshalled DataPoints), replay-and-diff (re-issues the same queries against current state and diffs byte-identically via proto.Equal; tolerant of per-query failures, fails only on divergence), pprof-grab (heap.pb.gz + goroutine.txt). cmd/soak-driver/catalog/default.json (9 LOC) — single query against the seeded soak_metric. Limit raised so 1000-row seeds aren't truncated to BanyanDB's default 100. scripts/soak-vectorized.sh (329 LOC) — orchestrator. SMOKE=1 runs ~25 min for end-to-end validation. Captures host UID/GID. Cleanup trap on SIGINT/TERM/EXIT. Goroutine count parsed from "goroutine profile: total N" header. docs/soak/g5d-runbook.md (265 LOC) — start-to-finish instructions, artefact layout, and how each artefact maps to the four spec acceptance criteria. Smoke (SMOKE=1, ~25 min) validated end-to-end on this branch: - 1000 rows seeded, 954 captured in baseline (95.4%, edge-truncation) - 20+ replay-and-diff iterations, all PASS (0 divergences) - 23 pprof captures spanning the 20-min Phase 1 window - Goroutine count: 556 → 556 (0% drift, threshold ≤5%) - MemoryTracker alerts: 0 - Final parity_pass=true, exit 0 - Memory peak (docker stats during smoke): banyandb ~110 MB, oap ~590 MB, no OOM kills against the 2 GB / 1 GB caps. Eleven smoke iterations were needed during bring-up; root-cause notes left in the script's comments where they shape config (5s flush timeouts, ms-truncated timestamps, 100-row default query Limit, root paths defaulting to /tmp). Deferred: - The 48 h run itself: harness is ready, calendar window is yours. - kind/k8s deployment shape: not needed for the four G5d criteria; runbook documents how to scale duration via env vars. --- .gitignore | 4 + cmd/soak-driver/catalog/default.json | 9 + cmd/soak-driver/main.go | 649 +++++++++++++++++++++++++++++++++++ docs/soak/g5d-runbook.md | 265 ++++++++++++++ scripts/soak-vectorized.sh | 329 ++++++++++++++++++ test/soak/Dockerfile.banyand | 52 +++ test/soak/docker-compose.soak.yaml | 235 +++++++++++++ 7 files changed, 1543 insertions(+) diff --git a/.gitignore b/.gitignore index 4785e2c8b..59896f986 100644 --- a/.gitignore +++ b/.gitignore @@ -87,3 +87,7 @@ fodc/agent/internal/ktm/iomonitor/ebpf/generated/vmlinux.h # Vectorized benchmark report artifacts (G5a) dist/bench/ +# G5d soak harness runtime artifacts +dist/soak/ +test/soak/data/ + diff --git a/cmd/soak-driver/catalog/default.json b/cmd/soak-driver/catalog/default.json new file mode 100644 index 000000000..b78cf5ece --- /dev/null +++ b/cmd/soak-driver/catalog/default.json @@ -0,0 +1,9 @@ +[ + { + "name": "soak_metric", + "groups": ["soak"], + "field_projection": { + "names": ["value", "count"] + } + } +] diff --git a/cmd/soak-driver/main.go b/cmd/soak-driver/main.go new file mode 100644 index 000000000..85d962a25 --- /dev/null +++ b/cmd/soak-driver/main.go @@ -0,0 +1,649 @@ +// Licensed to Apache Software Foundation (ASF) under one or more contributor +// license agreements.

Any non-zero line count is a +failure; see the **Failure Modes** section. + +`summary.json` also records `"memory_alert_lines"` for CI consumption. + +### Criterion 4 — No goroutine leak (heap delta ≤5%) + +Compare the goroutine counts in the start and end profiles: + +```bash +# Count goroutines in start profile +grep -c '^goroutine ' dist/soak/<ts>/pprof-start/goroutine-*.txt + +# Count goroutines in end profile +grep -c '^goroutine ' dist/soak/<ts>/pprof-end/goroutine-*.txt +``` + +Calculate ratio: `end / start`.

Check `banyand.log` for context around the alert timestamp. +2. Reduce query concurrency in `catalog/default.json` (fewer simultaneous + queries) or lower field projections. +3. If the budget is misconfigured, adjust the BanyanDB `--measure-memory-budget` + flag in the compose service command. + +### Goroutine leak + +**Symptom**: `goroutine_count_end / goroutine_count_start > 1.05`. + +**Action**: +1. Diff the goroutine profiles: + ```bash + diff dist/soak/<ts>/pprof-start/goroutine-*.txt \ + dist/soak/<ts>/pprof-end/goroutine-*.txt | head -80 + ``` +2. Identify which goroutine stacks appear only in the end profile. +3. File a bug against the vectorized pipeline with the diffed profiles attached. + +### Parity divergence + +**Symptom**: Any `diff-*.json` has `"pass": false`; `summary.json` +`"final_parity_pass"` is `false`. + +**Action**: +1. Open the failing diff file: + ```bash + jq '.divergences' dist/soak/<ts>/diff-<ts>.json + ``` +2. The `first_diffs` array shows the first 3 mismatched data points (index, + baseline string, replay string). +3. Reproduce the query manually: + ```bash + bin/soak-driver replay-and-diff \ + --addr localhost:17912 \ + --catalog cmd/soak-driver/catalog/default.json \ + --baseline dist/soak/<ts>/baseline.json \ + --report /tmp/debug-diff.json + ``` +4. Check whether the divergence is in field values, tag values, or shard IDs. +5. File a bug against the vectorized query path with the diff JSON attached. + +### OOMKill + +**Symptom**: A container disappears; `docker compose ps` shows it as `exited`. + +**Action**: +1. `docker inspect <container> | jq '.[].State.OOMKilled'` — if `true`, the + container exceeded its memory limit. +2. Check `docker stats` history for which container breached its limit. +3. The per-container limits in `test/soak/docker-compose.soak.yaml` must be + respected. Do **not** increase them without re-evaluating the host budget. +4. If BanyanDB OOM-kills, reduce the vectorized batch size or the number of + concurrent queries in the catalog. + +## Rollback + +To run Phase 1 with the flag disabled (reproducing the baseline behaviour): + +```bash +BANYANDB_VEC_ENABLED=false \ +SOAK_DATA_DIR=./test/soak/data \ +docker compose -f test/soak/docker-compose.soak.yaml up -d +``` + +This is also the normal state after any failed Phase 1: tear down the stack +with `docker compose -f test/soak/docker-compose.soak.yaml down -v` and +restart with `BANYANDB_VEC_ENABLED=false`. diff --git a/scripts/soak-vectorized.sh b/scripts/soak-vectorized.sh new file mode 100755 index 000000000..b47048dfd --- /dev/null +++ b/scripts/soak-vectorized.sh @@ -0,0 +1,329 @@ +#!/usr/bin/env bash +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.
