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 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).
