From 2dceaa96b675a64ac7e74731cbe2d07de9980f33 Mon Sep 17 00:00:00 2001 From: AndrewSillifant Date: Thu, 22 Oct 2026 16:44:17 -0600 Subject: [PATCH 01/10] metrics: keep a long run's driver log continuous; guard ingest_ratio kubectl logs -f is severed at the kubelet streamingConnectionIdleTimeout (4h on the test cluster) and nothing restarted it, so a 24h record held only the first ~4h of batches. A kept-up bronze then read as a fraction of itself: a live AML run reported ingest_ratio 0.24 while its lag never exceeded ~250s and silver never ran dry. - _driver_log_capture: restart a severed tail in place with --since-time from the last stamp already captured, so the file stays one continuous log per pod. A still-live tail is left alone; a new pod uid is still a resubmit with its own file. Add _last_stamp and tests for it and the existing (untested) merge_logs seam dedup. - collector: record max_batch_id per stage and refuse to score ingest_ratio when the bronze log has a gap over 10% of its batches (bronze_log_incomplete), reporting ingest_ratio_unscored_reason instead of a false shortfall verdict. verdict surfaces it as a warning, not a FAIL. Also add the 1.7.10 silver.accounts balance-state columns (last_entry_seq, last_book_ts) to the ensure_column upgrade path in both the batch and stream financial scripts, so a catalog created before 1.7.10 and reused across the upgrade does not fail the first write / micro-batch on a schema mismatch. --- src/lakebench/cli/_driver_log_capture.py | 99 ++++++++++++++++--- src/lakebench/metrics/collector.py | 51 +++++++++- src/lakebench/metrics/verdict.py | 7 +- .../spark/scripts/silver_build_financial.py | 7 ++ .../spark/scripts/silver_stream_financial.py | 7 ++ tests/test_continuous_trickle_rate.py | 40 ++++++++ tests/test_driver_log_capture.py | 78 +++++++++++++++ 7 files changed, 269 insertions(+), 20 deletions(-) create mode 100644 tests/test_driver_log_capture.py diff --git a/src/lakebench/cli/_driver_log_capture.py b/src/lakebench/cli/_driver_log_capture.py index 53fd42bc7..ab740d458 100644 --- a/src/lakebench/cli/_driver_log_capture.py +++ b/src/lakebench/cli/_driver_log_capture.py @@ -277,12 +277,29 @@ def _poll_once(self) -> None: continue if phase and phase not in ("Running", "Succeeded", "Failed"): continue - # If we already captured THIS uid, skip.

The gate turned that into FAILED-and-unscored, discarding the run's silver, freshness and detection evidence: the live 1.7.9/1.7.10 24h runs failed for this reason while bronze and silver kept up. Two further faults fed it: the continuous in-stream rounds fell through to run_power's 300 s default while financial batch used 900 s, and QpH was computed over the queries that passed, so a round that lost its heavy queries kept a higher QpH and a degrading series could read as improving. Separate the query SLA from the pipeline verdict: - QueryExecutorResult/QueryResult carry timed_out; the four executor timeout paths set it (Trino client timeout AND the server-side EXCEEDED_TIME_LIMIT that query_max_run_time raises ~5 s earlier, spark-thrift, duckdb remote + local). - is_sla_crossing() is the single definition of a crossing: a FAILED query that timed out AND passed in some round of this run. Both the CLI gate (_benchmark_gate_problems, passed_ever) and the metrics.json verdict re-derivation (_failed_queries) call it, so the exit code and the stored/report verdict cannot disagree. A timeout on a query that never passed, and every non-timeout error, still fail (the 8d3d383d 1-of-8 hole stays closed). Batch mode passes passed_ever=None: a timeout fails as before. - round_is_scorable() excludes any round with a real failure (not a Q9 contention miss, not a demoted crossing) from the composite/median QpH, trend and aggregate, so a degrading series cannot read as improving. - bench_query_timeout(cfg) (900 financial / 300 c360) is now the one limit both batch and continuous use; continuous records it in benchmark_query_timeout_seconds. It is also the limit a crossing is measured against. - Each crossing is recorded on its round (query_sla_crossings) with that round's silver_data_file_count. Also drop test_delta_thrift_q2_failure_fails_the_run: the gate has no tolerated-query carve-out left, so it only re-asserted the generic any-failure path. --- src/lakebench/benchmark/result.py | 26 +++++++ src/lakebench/benchmark/runner.py | 8 +++ src/lakebench/cli/_run.py | 42 +++++++++-- src/lakebench/cli/_sustained.py | 45 +++++++++++- src/lakebench/metrics/collector.py | 72 ++++++++++++++++--- src/lakebench/metrics/metric_registry.py | 20 ++++++ src/lakebench/metrics/verdict.py | 22 +++++- .../modules/query_engines/duckdb/executor.py | 5 +- .../query_engines/duckdb/local_executor.py | 1 + .../query_engines/spark_thrift/executor.py | 1 + .../modules/query_engines/trino/executor.py | 16 +++++ tests/test_benchmark_gate.py | 51 ++++++++++--- 12 files changed, 281 insertions(+), 28 deletions(-) diff --git a/src/lakebench/benchmark/result.py b/src/lakebench/benchmark/result.py index e08e69d18..933436881 100644 --- a/src/lakebench/benchmark/result.py +++ b/src/lakebench/benchmark/result.py @@ -24,12 +24,38 @@ class QueryExecutorResult: # The tag the engine was told to label this query with, for engines that # can report per-query storage I/O afterwards (Trino).

A failed query is now a crossing, exempt from the gate, only when it failed by exceeding its time limit **and** succeeded in some round of this run; the round and that round's silver data-file count are recorded under the round's `query_sla_crossings`. A timeout on a query that never passed, and every non-timeout error, still fail the run, so a run where queries genuinely broke is still marked FAILED (the 1-of-8-passing hole that the gate was added to close stays closed). A round that lost a query to a crossing is left out of the composite/median QpH, the QpH trend and the aggregate, because QpH is computed over the queries that passed and would otherwise read a degrading series as improving. The CLI exit, the stored verdict and `lakebench report` share one crossing definition, so they cannot disagree. Batch mode is unchanged: with no earlier round to cross from, a timeout fails as before. A run whose every benchmark query stays inside its limit for the whole window scores exactly as before. +- **The continuous in-stream benchmark rounds now use the same per-query time limit as the batch benchmark (900 s for financial, 300 s for Customer 360), and record it in `benchmark_query_timeout_seconds`.** The in-stream rounds passed no limit and fell through to the 300 s default, so a financial continuous run held its analytical queries to 300 s while a financial batch run of the same queries allowed 900 s; a query between those bounds timed out in continuous but not in batch, which read as a failed query rather than a slow one. The limit is now one value for both modes and is also the limit a crossing is measured against. A continuous Customer 360 run is unchanged (its limit was already 300 s); a financial continuous run's query timings are now comparable to the batch run's. +- **`ingest_ratio` is reported not-scored when the bronze driver log is incomplete, instead of as a shortfall computed from a truncated row count.** `kubectl logs -f` is severed at the kubelet's streaming-connection idle timeout (four hours on the validated cluster) and nothing restarted it, so a run longer than that held only the batches before the cut; the ratio's numerator then counted a fraction of the rows bronze actually ingested and a bronze that kept up read as having fallen behind (a 24-hour AML run reported `ingest_ratio` 0.24 while its datagen-to-bronze lag never exceeded about 250 s and silver never ran dry). The run now restarts a severed capture in place from the last timestamp it holds, so the log stays continuous, and the collector refuses to score `ingest_ratio` when the bronze log still has a gap over a tenth of its batches, recording `bronze_log_incomplete` and `ingest_ratio_unscored_reason` rather than a false verdict. A run whose bronze log is complete (any run under four hours, or any run once a severed capture resumes) is scored as before. + +### Fixed + +- **A `silver.accounts` table created before 1.7.10 and reused across the upgrade no longer fails the first batch build or stream micro-batch on a schema mismatch.** 1.7.10 added `last_entry_seq` and `last_book_ts` to `silver.accounts`, but neither the batch build nor the stream added them to the catalog's existing table on the upgrade path, so a reused pre-1.7.10 `silver.accounts` left `CREATE TABLE IF NOT EXISTS` a no-op and the first accounts overwrite (batch) or prior-state read (stream) failed on the missing columns. Both scripts now add the two columns on startup, the same idempotent upgrade step already used for the other post-DDL columns. A fresh deployment, or one created on 1.7.10 or later, is unaffected. + ## [1.7.10] - 2026-10-20 ### Breaking diff --git a/docs/benchmarks/aml/correctness.md b/docs/benchmarks/aml/correctness.md index bfc7c3a39..4f088eae1 100644 --- a/docs/benchmarks/aml/correctness.md +++ b/docs/benchmarks/aml/correctness.md @@ -28,13 +28,13 @@ at a fixed seed but not checked; check them from `metrics.json` | Batch bronze reached 95% of the scale's expected volume | record gate `scale_ratio` | yes | | No benchmark query outside `allow_empty` returned zero rows | record gate `query_answers` | yes | | TM invariants ([8.5](tm-operations.md#85-tm-operations)) | TM verdict (`metrics/tm_ops.py`) | only on `fail`; `unknown` (an unchecked invariant, an interrupted pass, an unparsed cycle log), `not_run` and `disabled` warn | -| Any failed query; a non-`allow_empty` query with 0 rows | benchmark gate | yes.

Bronze resume-seam rows were double-counted. committed_writes returned every write event, and the callers sum rows per event, so the ~1 s --since-time overlap a resumed capture re-fetches counted the seam batch's rows twice. committed_writes now returns one write per batch id (silver already dedups the same way via a per-ident dict), so a duplicate from a resume seam, or any cause, is counted once. 2. The gap guard false-tripped on sparse bronze batch ids. Bronze empty and replay-skipped batches log an id but no "writing" line, so the counted ids are not contiguous even on a complete log; (max_id + 1 - count) / (max_id + 1) over 0.1 then suppressed ingest_ratio on a run with many empty triggers. The guard now reads the largest run of consecutive missing ids (max_batch_id_gap, computed at parse time): a severed capture drops thousands in one run, scattered empties make runs of 1, so one distinguishes a truncated log from a sparse one. Bound is 50 consecutive ids. Tests: bronze seam duplicate counts each batch once; scattered empty batches (gap of 1) do not false-trip; a 240-id gap does. --- src/lakebench/metrics/collector.py | 65 ++++++++++++++-------- src/lakebench/metrics/continuous_window.py | 19 +++++-- tests/test_continuous_trickle_rate.py | 30 +++++----- tests/test_continuous_window.py | 41 ++++++++++++++ 4 files changed, 115 insertions(+), 40 deletions(-) diff --git a/src/lakebench/metrics/collector.py b/src/lakebench/metrics/collector.py index c8eacdd96..81df82631 100644 --- a/src/lakebench/metrics/collector.py +++ b/src/lakebench/metrics/collector.py @@ -205,9 +205,12 @@ class StreamingJobMetrics: batch_size: int = 0 total_batches: int = 0 # Highest batch id in the driver log. total_batches - 1 when the capture is - # complete; a large gap (max+1 >> count) means the log lost a run of - # batches (a severed kubectl logs -f), which undercounts bronze rows. + # complete; a large gap means the log lost a run of batches (a severed + # kubectl logs -f), which undercounts bronze rows. max_batch_id: int | None = None + # Largest run of consecutive missing batch ids.

A failed query is now a crossing, exempt from the gate, only when it failed by exceeding its time limit **and** succeeded in some round of this run; the round and that round's silver data-file count are recorded under the round's `query_sla_crossings`. A timeout on a query that never passed, and every non-timeout error, still fail the run, so a run where queries genuinely broke is still marked FAILED (the 1-of-8-passing hole that the gate was added to close stays closed). A round that lost a query to a crossing is left out of the composite/median QpH, the QpH trend and the aggregate, because QpH is computed over the queries that passed and would otherwise read a degrading series as improving. The CLI exit, the stored verdict and `lakebench report` share one crossing definition, so they cannot disagree. Batch mode is unchanged: with no earlier round to cross from, a timeout fails as before. A run whose every benchmark query stays inside its limit for the whole window scores exactly as before. - **The continuous in-stream benchmark rounds now use the same per-query time limit as the batch benchmark (900 s for financial, 300 s for Customer 360), and record it in `benchmark_query_timeout_seconds`.** The in-stream rounds passed no limit and fell through to the 300 s default, so a financial continuous run held its analytical queries to 300 s while a financial batch run of the same queries allowed 900 s; a query between those bounds timed out in continuous but not in batch, which read as a failed query rather than a slow one. The limit is now one value for both modes and is also the limit a crossing is measured against. A continuous Customer 360 run is unchanged (its limit was already 300 s); a financial continuous run's query timings are now comparable to the batch run's. -- **`ingest_ratio` is reported not-scored when the bronze driver log is incomplete, instead of as a shortfall computed from a truncated row count.** `kubectl logs -f` is severed at the kubelet's streaming-connection idle timeout (four hours on the validated cluster) and nothing restarted it, so a run longer than that held only the batches before the cut; the ratio's numerator then counted a fraction of the rows bronze actually ingested and a bronze that kept up read as having fallen behind (a 24-hour AML run reported `ingest_ratio` 0.24 while its datagen-to-bronze lag never exceeded about 250 s and silver never ran dry). The run now restarts a severed capture in place from the last timestamp it holds, so the log stays continuous, and the collector refuses to score `ingest_ratio` when the bronze log still has a gap over a tenth of its batches, recording `bronze_log_incomplete` and `ingest_ratio_unscored_reason` rather than a false verdict.

Cut those; keep every scoring, gate, destroy-safety, ownership, exit-code and held-out-seed test. - Developer tooling: drop the pre-push hook, gitleaks history and baseline, and calendar-leakage tests; trim release_gate, package_guard (held-out seed checks kept) and check_version. Drop the fixture scrubber's rule tests; keep fixture-is-clean and the golden records. - Review-session files (saf*, cfg*, rpt1_er*, *_v16, lb148, evd5, category1, equivalence_review_fixes) are merged into their module's test file or renamed by topic, without ticket ids. - Same-branch parametrization, tautologies against a module's own constants, pydantic behaviour, exact console/HTML wording, call counts and private helpers: shrunk or cut. The continuous sizing grid and the interrupt and scale-invariance harness runs take far fewer cases. - Dead code the cut tests held up: config/_readers.py (only the schema walk imported it), collector.SNAPSHOT_SOURCE_FIELDS, and the LB_SILVER_TEST_ALLOW_EMPTY bypass in common.py, which nothing set.
