File

Description

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

FileSource is meant for development purposes only and is not optimized for production use.

Example

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.

Supported Types

File data sources support all eight primitive types and their corresponding array types. For a comparison against other batch data sources, please see here.
