From 871726b007c34a2648cfe399a548915bb060d298 Mon Sep 17 00:00:00 2001 From: Kevin Longe <273747162+kvlonge@users.noreply.github.com> Date: Wed, 11 Nov 2026 09:24:23 +0000 Subject: [PATCH 1/3] test(perf): scale the cache compile guards to the runner and restore the 1.10x cold ratio The fresh-process cache guards failed on runner speed alone: cold wall and CPU spread 1.6x to 1.9x between hosted runner classes, while cold over the in-job cache-disabled control stayed within 1.05 on CPU. Their wall budgets now scale by the fixed calibration workload the dense guards already use. A slower compiler is caught by the same-runner base/head comparisons. Their cold and model analysis allowances were sized against main before native analysis; main now has it on both sides, and recent readings sit at 0.95 to 1.03, so they return to 1.10x. An injected slowdown of 20% of cold wall fails the restored limit at 1.234. --- .github/workflows/verify.yml | 14 +------ .../main/compile/COMPILE_BENCHMARKS.md | 12 +++--- .../compile/test_dense_compile_performance.py | 4 +- ...fresh_process_compile_cache_performance.py | 37 ++++++++++++------- .../test_fresh_process_compile_performance.py | 4 +- 5 files changed, 36 insertions(+), 35 deletions(-) diff --git a/.github/workflows/verify.yml b/.github/workflows/verify.yml index cbec652280..22711433e8 100644 --- a/.github/workflows/verify.yml +++ b/.github/workflows/verify.yml @@ -845,20 +845,10 @@ jobs: include: - kind: dense max_ratio: "1.10" - # Temporary native-analysis allowance on the cold compile only; restore 1.10 when the - # native analysis cold path is optimised.

A build that would have succeeded ended failed. The scheduler loop and platform maintenance now retry their next cycle after a transient store failure (SQLite busy or locked, or the existing transient PostgreSQL errors). Every write still rechecks the scheduler lease, and a retry reruns claim recovery so a claim with an uncertain commit is still adopted. The API answers a transient store failure with 503, and workers retry such a run report with the same event ID. A worker finalized before its child started publishes its launch failure first. A run whose adopted worker stopped on its own after a restart now fails with a reason that names the restart. --- .../orchestration/busy_control_store.json | 4 ++ .../orchestration/lost_worker_restart.json | 4 ++ .../src/workers/_helpers/recovery.rs | 1 + .../src/workers/_helpers/supervisor.rs | 23 ++++++++- crates/sqlbuild-cli/src/workers/models.rs | 2 + .../sqlbuild-orchestration/src/api/errors.rs | 7 +++ .../src/platform/main/run_maintenance.rs | 8 ++- .../src/scheduler/main/run_scheduler.rs | 29 ++++++++--- .../src/scheduler/types.rs | 3 ++ .../src/store/errors.rs | 13 +++++ .../_helpers/compiled_project/constants.rs | 2 + .../compiled_project/snapshot_worker.rs | 16 ++++-- .../publication/test_local_recovery.py | 49 +++++++++++++++++++ .../publication/test_worker.py | 39 +++++++++++++++ 14 files changed, 187 insertions(+), 13 deletions(-) create mode 100644 benchmarks/duckshop/edge_cases/orchestration/busy_control_store.json create mode 100644 benchmarks/duckshop/edge_cases/orchestration/lost_worker_restart.json diff --git a/benchmarks/duckshop/edge_cases/orchestration/busy_control_store.json b/benchmarks/duckshop/edge_cases/orchestration/busy_control_store.json new file mode 100644 index 0000000000..ffe74d65fa --- /dev/null +++ b/benchmarks/duckshop/edge_cases/orchestration/busy_control_store.json @@ -0,0 +1,4 @@ +{ + "description": "Another connection holds the SQLite control store's write lock for longer than the store's busy timeout while a scheduled build's warehouse statement is running.

<273747162+kvlonge@users.noreply.github.com> Date: Wed, 11 Nov 2026 09:56:28 +0000 Subject: [PATCH 3/3] fix: keep workers from restarting nodes the planner already skipped A scheduled build reported a source-freshness skip as finished and then reported the same node as started when the executor reached it. The control API rejects that change, so the worker stopped and every node it had not reached yet ended skipped, including branches independent of the stale source. Workers now never report a start for a node whose outcome is already final. --- .../orchestration/worker_freshness_skip.yml | 16 +++++ .../compiled_project/snapshot_execution.rs | 10 ++- .../publication/test_worker.py | 65 +++++++++++++++++++ 3 files changed, 89 insertions(+), 2 deletions(-) create mode 100644 benchmarks/duckshop/edge_cases/orchestration/worker_freshness_skip.yml diff --git a/benchmarks/duckshop/edge_cases/orchestration/worker_freshness_skip.yml b/benchmarks/duckshop/edge_cases/orchestration/worker_freshness_skip.yml new file mode 100644 index 0000000000..0d8f9d076e --- /dev/null +++ b/benchmarks/duckshop/edge_cases/orchestration/worker_freshness_skip.yml @@ -0,0 +1,16 @@ +# A scheduled build where raw_orders fails its freshness check and raw_returns has none. +# The planner skips the models that read raw_orders before execution; the worker must never +# report those skips as started, and models that read raw_returns must still build. +sources: + - name: raw_orders + description: Raw orders. + expression: SELECT 1 AS order_id + freshness: + strategy: sql + type: timestamp + query: SELECT CAST('2000-01-01 00:00:00' AS TIMESTAMP) AS data_version + age_policy: + error_after: 1h + - name: raw_returns + description: Raw returns. + expression: SELECT 2 AS return_id diff --git a/crates/sqlbuild-python/src/bindings/_helpers/compiled_project/snapshot_execution.rs b/crates/sqlbuild-python/src/bindings/_helpers/compiled_project/snapshot_execution.rs index a5fe394f0d..f5fc5b8bbe 100644 --- a/crates/sqlbuild-python/src/bindings/_helpers/compiled_project/snapshot_execution.rs +++ b/crates/sqlbuild-python/src/bindings/_helpers/compiled_project/snapshot_execution.rs @@ -213,10 +213,16 @@ impl WorkerBuild { self.start_key(py, &format!("{kind}:{name}")) } - /// Report a selected node as started; the deterministic event ID makes a repeat a no-op. + /// Report a selected node as started unless its outcome is final, such as a planner skip. pub(crate) fn start_key(&self, py: Python<'_>, key: &str) -> PyResult<()> { self.check_cancelled(py)?; - if self.execution.claim.request.selection.contains(key) { + if self.execution.claim.request.selection.contains(key) + && !self + .completed + .lock() + .map_err(|_| poisoned())? + .contains_key(key) + { self.worker.bind(py).get().change( py, &format!("node-started/{key}"), diff --git a/tests/integration/src/sqlbuild/compiler/compiled_project/publication/test_worker.py b/tests/integration/src/sqlbuild/compiler/compiled_project/publication/test_worker.py index 0fb2cbabee..f6b52e8b39 100644 --- a/tests/integration/src/sqlbuild/compiler/compiled_project/publication/test_worker.py +++ b/tests/integration/src/sqlbuild/compiler/compiled_project/publication/test_worker.py @@ -193,6 +193,71 @@ def test_given_a_scheduled_group_when_workers_execute_then_dependencies_and_fail assert warehouse.sql(test_case.warehouse_query).fetchall() == test_case.expected_rows +@pytest.mark.parametrize( + "test_case", + [ + WorkerExecutionTestCase( + "a stale source blocks only its own branch", + "SELECT 11 AS amount", + "SELECT amount FROM orders UNION ALL SELECT return_id FROM returns ORDER BY 1", + "partial", + [(2,), (11,)], + files={ + "sources/raw.yml": Path( + "benchmarks/duckshop/edge_cases/orchestration/worker_freshness_skip.yml" + ).read_text(), + "models/stale_orders.sql": ( + "MODEL (description 'Stale orders.', materialized table);\n" + 'SELECT order_id FROM __source("raw_orders")\n' + ), + "models/late_orders.sql": ( + "MODEL (description 'Late orders.', materialized table);\n" + 'SELECT order_id FROM __source("raw_orders")\n' + ), + "models/returns.sql": ( + "MODEL (description 'Returns.', materialized table);\n" + 'SELECT return_id FROM __source("raw_returns")\n' + ), + "orchestration/orders.py": ( + "from sqlbuild.orchestration import job, schedule\n" + 'annual_orders = job("annual_orders", ' + 'select="orders stale_orders late_orders returns", ' + 'description="Build orders.", ' + 'schedule=schedule(cron="0 0 * * *", timezone="UTC", ' + 'starts_at="2000-01-01T00:00:00Z"))\n' + ), + }, + ) + ], + ids=lambda case: case.description, +) +def test_given_a_stale_source_when_a_worker_builds_then_blocked_nodes_finish_skipped_unstarted( + test_case: WorkerExecutionTestCase, tmp_path: Path, monkeypatch: pytest.MonkeyPatch +) -> None: + with scheduled_worker(tmp_path, monkeypatch, test_case) as worker: + run: dict[str, Any] = wait_for_run( + worker.api, worker.process, worker.log, job_key="annual_orders" + ) + assert run["status"] == test_case.expected_status, worker.log.read_text() + with sqlite3.connect(worker.control_store) as control: + nodes: list[tuple[str, str, bool]] = [ + (key, status, started is not None) + for key, status, started in control.execute( + "SELECT node_key, status, started_at FROM sqb_run_nodes " + "WHERE run_id=?
