Sirius: A GPU-native SQL engine

news.ycombinator.com Unknown 2026-02-16 18:18:18

Sirius is a GPU-native SQL engine. It plugs into existing databases such as DuckDB via the standard Substrait query format, requiring no query rewrites or major system changes. Sirius currently supports DuckDB and Doris (coming soon), other systems marked with * are on our roadmap. Performance Running TPC-H on SF=100, Sirius achieves ~10x speedup over existing CPU query engines at the same hardware rental cost, making it well-suited for interactive analytics, financial workloads, and ETL jobs.
