File data sources allow for the retrieval of historical feature values from files on disk for building training datasets, as well as for materializing features into an online store.
FileSource is meant for development purposes only and is not optimized for production use.
Example
Configuration options are available .
from feast import FileSource
from feast.data_format import ParquetFormat
parquet_file_source = FileSource(
file_format=ParquetFormat(),
