TPC-DS benchmark

The industry-standard TPC-DS decision-support benchmark: 99 analytical queries (01.sql ... 99.sql) over a retail snowflake schema. Compared to TPC-H it has many more queries, a wider schema, and heavier use of joins, subqueries, and window functions, making it a broad regression net for scan and pushdown behavior.

The benchmark harness lives in src/tpcds.

CI variant

CI runs this suite at scale factor 1 from local NVMe as the TPC-DS SF=1 on NVME PR comment, comparing DataFusion and DuckDB over Parquet, Vortex, and vortex-compact files (plus a native DuckDB baseline).

Running locally

vx-bench run tpcds --engine datafusion,duckdb --format parquet,vortex --opt scale-factor=1.0
