# File

## Description

* Only Parquet files are currently supported.
* All data is downloaded and joined using Python and may not scale to production workloads.

## Example

{% code title="feature\_store.yaml" %}

```yaml
project: my_feature_repo
registry: data/registry.db
provider: local
offline_store:
  type: file
```

{% endcode %}
