# Overview

The Alvin Query Optimizer is built in pure, high performance [Rust](https://www.rust-lang.org/) and leverages [Apache DataFusion](https://datafusion.apache.org/) to parse and transpile SQL. Cool tech aside, the most important thing is the results we are achieving — on average saving our customers 52% on their BigQuery spend, automatically though:

* **Query acceleration:** Our powerful query accelerator, built on Apache DataFusion, uses semantic analysis and logical plan rewriting to optimize your queries for maximum performance.
* **Resource optimization:** Take advantage of the most cost-effective pricing model for every query. Alvin dynamically routes your queries to the cheapest and most efficient compute.
* **Intelligent caching:** BigQuery's cache can be fragile. Alvin optimizes your workloads to maximise cache hits. More cache hits means near-instant results with zero cost.
