Configuration Reference

Overview

This reference describes how to configure Feast components:

1. Feast Core and Feast Online Serving

Available configuration properties for Feast Core and Feast Online Serving can be referenced from the corresponding application.yml of each component:

Configuration properties for Feast Core and Feast Online Serving are defined depending on Feast is deployed:

Docker Compose Deployment

For each Feast component deployed using Docker Compose, configuration properties from application.yml can be set at:

Kubernetes Deployment

A reference of the sub-chart-specific configuration can found in its values.yml:

Configuration properties can be set via application-override.yaml for each component in values.yaml:

Direct Configuration

If Feast is built and running from source, configuration properties can be set directly in the Feast component's application.yml:

2. Feast CLI and Feast Python SDK

1. Command line arguments or initialized arguments: Passing parameters to the Feast CLI or instantiating the Feast Client object with specific parameters will take precedence above other parameters.

# Set option as command line arguments.
feast config set core_url "localhost:6565"

# Pass options as initialized arguments.
client = Client(
    core_url="localhost:6565",
    project="default"
)

2. Environmental variables: Environmental variables can be set to provide configuration options. They must be prefixed with FEAST_. For example FEAST_CORE_URL.

FEAST_CORE_URL=my_feast:6565 FEAST_PROJECT=default feast projects list

3. Configuration file: Options with the lowest precedence are configured in the Feast configuration file. Feast looks for or creates this configuration file in ~/.feast/config if it does not already exist. All options must be defined in the [general] section of this file.

[general]
project = default
core_url = localhost:6565

3. Feast Java and Go SDK

The Feast Java SDK and Feast Go SDK are configured via arguments passed when instantiating the respective Clients:

Go SDK

// configure serving host and port.
cli := feast.NewGrpcClient("localhost", 6566)

Visit the Feast Go SDK API reference to learn more about available configuration parameters.

Java SDK

// configure serving host and port.
client = FeastClient.create(servingHost, servingPort);
