Analytical queries over a large web analytics table.
Readiness reviewed 2026-10-04. Local fixture and offline checks are development evidence; they do not establish benchmark performance.
Implemented
Upstream schema and query sources are pinned, with all 43 ClickHouse queries registered.
Corpus preparation and storage upload tooling have local fixture checks.
All 43 DuckDB translations execute on a synthetic Parquet fixture; nine queries also have independent answer checks. Canonical-data performance is still unmeasured.
Before results can be published
Freeze and verify the canonical dataset.
Complete engine query translations and compare their answers with an independent oracle; report unsupported operations explicitly.
Qualify independent cold and warm runs and publish reviewed measurements.
Measurements to report
Query p50 / p95, independent cold and warm executions
Coverage is targeted across all eight engine configurations. Adapters, correctness checks and comparable measurements must be qualified before this suite is published. Unsupported operations will remain explicit coverage gaps.
