At 16× = ~16 K redis ops/s, Stirling can drain >88 MiB of `redis_events` rows in a single push if the perf buffer fills before draining. At 4× the same can happen if the drain stalls briefly (e.g., during a cgroup-procs scan, which we see warned about in the same log: +`W…state_manager.cc:276] Failed to read PID info for pod=…`). + +### 5. Why earlier 8× ran fine but later 4× crashed + +The two runs differ in **PEM's own background state**: +- The 16× run that triggered the original crash also had **k6 OOM cycling** (loadgen container limit 512 MiB at that time). When k6 restarted, the redis_events traffic gapped, then surged when k6 came back — a perfect setup for a single drained batch to be unusually large. +- The 4× run in sweep #2 inherited a PEM that had been restarting all day; one of those starts had higher steady-state perf-buffer occupancy and the next drain landed an >47 MiB batch. + +### 6.

So every `DFATAL` fires `abort()`. A release-mode PEM (which is what `ghcr.io/k8sstormcenter/pixie/vizier-adaptive_export_image:0.14.17` etc. would be) would have **logged the same error and dropped the batch**, *not crashed* — but it would still be losing data on every oversized push. + +## Mitigations + +### Already applied (live cluster, 2026-05-14 16:09) + +``` +kubectl set env daemonset/vizier-pem -n pl PL_TABLE_STORE_DATA_LIMIT_MB=4096 +``` + +New per-other-table cap: **152.9 MiB**.

Compilation error: `Expected two arguments to 'or'`. PxL parses Python's short-circuit `or` differently from element-wise truth-tests on Series. + +2. **`|` is also rejected.** Switched to `(df.pod == 'a') | (df.pod == 'b')` (pandas idiom). New error: `Operator '|' not handled`. PxL has no element-wise bitwise OR on Series. + +3. **`px.contains` is substring, not regex.** Tried `px.contains(df.pod, '^(p1|p2|...)$')` → script compiled but matched zero rows (substring search for the literal `^(...)$` text in pod names). Real regex UDF is `px.regex_match(pattern, input)` registered in `carnot/funcs/builtins/regex_ops.cc`. + +**Resolution**: `df = df[px.regex_match('^(p1|p2|...)$', df.pod)]` with full regex escaping of pod names defensively (k8s DNS-1123 doesn't admit regex metachars but a future rename rule might). + +**Throwaway-test count to discover this**: 3 deploys, ~10 min of iteration. Cheaper than debugging in tests because the failure mode is "pixie compiler rejects" — purely an integration surface. + +### 2026-05-17 — first successful 4× streaming sweep + +| Table | queries (5 min) | rows from pixie | flushes to CH | CH delta | +|---|---|---|---|---| +| http_events | 8 | 70,000 | 7 | 80,000 | +| redis_events | 8 | 70,000 | 7 | 80,000 | +| pgsql_events | 8 | 50,178 | 6 | 60,178 | +| dns_events | 8 | 1,706 | 4 | 1,706 | +| amqp/cql/mongo/mux/mysql/tls | 8-9 each | 0 | 0 | 0 | +| **Total** | **83** | **191,884** | **24** | **221,884** | + +**0 errors, 0 DeadlineExceeded.** + +vs rev-2 with manifest throttle defaults at the same 4× load: +- 78 fan-outs, 6-15 successful pushes +- pgsql_events: 20 rows in CH (the chronic starvation case) +- Total ~135k rows + +**Rev-3 delivered ~3000× more pgsql data than rev-2 with 1/10th the broker query count.** + +### Confirmed design wins + +1. **Even per-table workload distribution.** Each table got ~8 queries in 5 min — no table starved by others' larger payloads (the rev-2 pgsql failure mode). +2. **Empty tables are nearly free.** amqp/cql/etc. ran 8-9 queries each, all returning 0 rows. The cost is one network roundtrip per refresh; total wall budget for the 6 empty tables = trivial. +3. **No throttle knobs needed.** The bound IS the design: N tables × 1 query per refresh = O(N) broker concurrency = 10. The rev-2 knobs (per_hash, global, empty_skip) are completely unnecessary in this model. +4. **One ActiveSet seed worked.** Rehydrate-on-boot populated the streaming set from CH without race issues. + +### Remaining work (not in this slice) + +- Make `OnAttribution` non-blocking (today it's synchronous from controller.handle; if ActiveSet.Upsert blocks, it would back-pressure the controller). Not observed in the sweep, but a contention hazard. +- Wire pruner: PruneExpired ⇒ ActiveSet.Remove. Today the rev-3 ActiveSet only shrinks if Remove is called explicitly; the controller's OnPrune callback IS hooked up but the prune-grace timing means active pods linger past their nominal t_end for `2 * After` (10 min default). Probably fine, but worth measuring under longer load. +- Decide on the operational defaults for `ADAPTIVE_STREAM_REFRESH_SEC`, `ADAPTIVE_STREAM_BATCH_EVERY_SEC`, `ADAPTIVE_STREAM_MAX_WHITELIST`. Current sweep used 30 / 5 / 500 — all worked at this scale; need stress test to find limits. +- Delete rev-2 push path.

Filter coalescing reduced re-submissions to ~1 per ActiveSet change, regardless of the 12k anomalies/sec workload. +- Whitelist size cap (500) → **untested at scale**; sweep had only 6 pods. Future work. + +### 2026-05-17 — slice 2 (AttributionNotifier + TDD discipline) + +**New rule adopted**: TDD from now on, with unit tests as primary feedback and the 4× sweep as the integration gate. Memory entry: [TDD discipline](feedback_tdd.md). Catalyst: the rev-3 slice-1 work cost 3 redeploys (~30 min) discovering three independent PxL syntax errors that integration testing would have caught once. + +**Slice 2 scope**: a non-blocking `AttributionNotifier` between controller callbacks and the ActiveSet. Without it, a slow ActiveSet writer could pin `controller.handle` and back-pressure the trigger. + +**TDD process (round 1 — Notifier)**: +1. Wrote 7 unit tests first → red (undefined symbols). +2. Wrote `notifier.go` (~140 LOC) → green except for one test asserting "0 drops on 50 events in 32-buffer" which was over-strict (producer outraced consumer on first burst). +3. Relaxed the test to use buffer >> burst + inter-submit yield — passes. + +**Net cost vs slice-1's "deploy + observe" loop**: ~5 min for the whole cycle vs 30 min for slice-1 — and the tests stay as regression coverage. + +**TDD process (round 2 — controller callbacks)**: +1. Added 4 new tests for `OnAttribution` + `OnPrune` behavior: + - `TestController_OnAttribution_FiresPerEvent` + - `TestController_OnAttribution_NilIsNoop` + - `TestController_OnPrune_FiresWithKeyDetails` + - `TestController_OnPrune_NilIsNoop` + - `TestController_OnPrune_DoesNotHoldMutex` ← caught a real concern: callback under lock would deadlock +2. All 5 passed first run — the earlier refactor of `PruneExpired` to collect-under-lock-then-fire-after-release was already correct. + +**TDD process (round 3 — end-to-end integration)**: +1. Added 3 integration tests against fake querier + fake sink: + - `TestIntegration_NotifierToScannerWhitelistFlow` — green first try. + - `TestIntegration_EmptyActiveSetSkipsAllQueries` — green first try. + - `TestIntegration_PrunePropagatesToScannerWhitelist` — RED first try because my assertion was wrong (looking at q.all()'s last entry, which stays stale when scanner correctly skips on empty whitelist). Fixed assertion: count post-Remove queries containing the pod (must be 0). Green. + +**Notable test discovery**: the "PrunePropagates" assertion bug taught me that the scanner's empty-whitelist short-circuit is *invisible* in q.all() — assertions on streams of side effects need to count NEW occurrences, not check the latest entry. + +### 2026-05-17 — slice 2 4× sweep result + +Same workload as slice 1.

When multiple anomaly hashes share one pod (e.g. pgsql-server has hashes for `postgres`, `pg_isready`, `runc:[2:INIT]`), pruning ONE hash would prematurely evict the pod from streaming. **Real bug.** +2. **`activeset.go:110`** — version-bump on pure t_end extension forces subscribers to re-snapshot for no reason. +3. **`activeset.go:183`** — Snapshot+Subscribe race; needs an atomic combined helper. + +**TDD round 4 — controller OnPrune per-pod:** +- 2 new tests RED first: `TestController_OnPrune_OnlyFiresWhenLastHashOnPodGone`, `TestController_OnPrune_DoesNotFireWhileOtherHashesActive` +- Implemented two-pass prune (delete expired, then for each pruned hash's pod check whether any surviving hash still references it; fire only for "no survivors") +- Green first run. + +**TDD round 5 — activeset version + atomic subscribe:** +- 2 new tests RED first: `TestUpsertExtendDoesNotAdvanceVersion`, `TestSubscribeAndSnapshot_RaceFreeBootstrap` +- Implemented: extension early-return before version bump; added `SubscribeAndSnapshot()` that captures keys + registers subscriber under one mutex +- Green first run. + +**TDD round 6 — scanner backoff:** +- 2 new tests RED first: `TestScanner_BackoffOnRepeatedErrors`, `TestScanner_BackoffResetsOnSuccess` +- Discovered existing backoff implementation worked correctly; second test needed assertion-tightening (flipFlopQuerier cycles, so error count isn't deterministic — relaxed to range checks). + +**TDD round 7 — whitelist cap boundaries:** +- 4 new tests, all green first run: `_CapBoundary_AtLimit`, `_CapBoundary_OneOverLimit`, `_CapBoundary_RecoversAfterShrink`, `_CapDisabled_AllowsAnySize` +- No code changes needed — existing `computeFilter` already correctly handled all four cases. + +**Flake found + fixed**: `TestIntegration_PrunePropagatesToScannerWhitelist` was flaky under load (3/5 pass). The original assertion checked "the last query doesn't contain the pruned pod" which is invalid when the scanner's empty-whitelist branch correctly SKIPS issuing queries (last entry stays stale).

PxL has a string-length limit; we'd cap the whitelist at e.g. 500 pods and emit a warning. Beyond that we'd switch to a "no filter" mode (stream everything). +4. **Stream stuck without errors** (silent hang): Healthcheck's "no records in 60s" trigger forces a re-submit. +5. **Operator restart**: same recovery as today — watermark + adaptive_attribution rehydrate. + +## What we'd rip out + +- All of `pushPixieRows` + the per-hash goroutine spawn in `controller.handle` +- All three throttle knobs (`MaxParallelQueriesPerHash`, `MaxInflightQueriesGlobal`, `EmptyResult*`) — no longer needed +- The `inFlight` map (no longer needed; stream lifecycle is centrally managed) +- The negative-cache (no longer needed; empty-set short-circuit is automatic) + +## What we'd keep + +- The trigger + persistent watermark (rev-2's biggest real win) +- The attribution sink (`Sink.Write` for `adaptive_attribution`) +- DDL + `Rehydrate` (still needed for ActiveSet startup) +- pixieapi direct-mode (still the transport for the 10 streams) + +## Open design decisions for you + +1. **Filter granularity in PxL**: `(pod, namespace)` whitelist vs `pod_uid` whitelist vs `upid` whitelist? Pod-name whitelist is simplest but stale if a pod gets recreated (the new pod's traffic would leak through). UID-based is correct but requires `px.pod_uid_to_pod_name` or similar. +2. **PxL re-submission cadence**: stream is logically "forever", but we re-submit on filter changes + periodically (60 s?) to bound staleness. Tradeoff: too frequent = broker chatter; too rare = up-to-60s lag for a new anomaly to start streaming its pod's data. +3. **Per-table CH batch size**: 10 k rows / 5 s is a guess. Larger batches → fewer INSERTs but worse latency-to-CH. +4. **What happens when active_set is permanently large** (e.g. all 100 pods in cluster have anomalies during an incident)? Do we cap and shed? Or fall back to no-filter "stream everything"? + +## Migration path + +Rev-3 can ship alongside rev-2 behind a feature flag (`ADAPTIVE_WRITE_MODE=streaming` vs `pull`).
