Extensions
The main goal of the `substrait` extension is to support both production and consumption of [Substrait](https://substrait.io/) query plans in DuckDB.  
This extension is mainly exposed via 3 different APIs – the SQL API, the Python API, and the R API.
Here we depict how to consume and produce Substrait query plans in each API.  
> The Substrait integration is currently experimental. Support is currently only available on request.
> If you have not asked for permission to ask for support, [contact us prior to opening an issue](https://duckdblabs.com/contact/).
> If you open an issue without doing so, we will close it without further review.
