# datafusion-tokomak

Experimental pluggable optimizer for DataFusion using graph rewriting.

The goal is to allow experimenting with the [Egg](https://github.com/egraphs-good/egg) library,

and experiment with a maintainable and aggresive optimization framework.

The optimizer is WIP.

Usage example:

```rust

 let mut ctx = ExecutionContext::with_config(

    ExecutionConfig::new().add_optimizer_rule(Arc::new(Tokomak::new())),

);

ctx.register_csv("example", "tests/example.csv", CsvReadOptions::new())?;

// create a DataFusion dataframe

let df = ctx

    .sql("SELECT price * 0 from example")?;

```
