## What it is
Sirius is a GPU-native SQL analytics engine written in C++ that accelerates query execution by offloading it to GPUs. It integrates with existing databases like DuckDB and Doris via the Substrait query format, requiring no query rewrites, and includes CPU fallback for compatibility.

## Use cases
- accelerate SQL analytics queries on GPUs
- speed up DuckDB workloads without rewriting queries
- run OLAP analytics 10x faster at the same hardware cost
- plug GPU acceleration into existing database stacks via Substrait
- deploy GPU-accelerated analytics on cloud or on-prem
- offload heavy analytical processing from CPU engines

## When to choose
- you have analytical SQL workloads bottlenecked by CPU execution
- you want GPU speedups without changing your existing database or queries
- you need Substrait-compatible query acceleration with CPU fallback
- you run large-scale OLAP analytics where hardware cost efficiency matters

## When to avoid
- you lack GPU hardware or cannot rent GPU instances
- your workload is mostly transactional (OLTP) rather than analytical
- you need a fully mature, battle-tested engine for critical production systems
- your queries are small and latency is dominated by data transfer to GPU

## Facets
