File data sources are files on disk or on S3. Currently only Parquet files are supported.

{% hint style="warning" %} FileSource is meant for development purposes only and is not optimized for production use. {% endhint %}

from feast import FileSource
from feast.data_format import ParquetFormat

parquet_file_source = FileSource(
    file_format=ParquetFormat(),
    path="file:///feast/customer.parquet",
)

The full set of configuration options is available here.
