# Feast Java Helm Charts (alpha)

This repo contains Helm charts for Feast Java components that are being installed on Kubernetes:

* Feast (root chart): The complete Helm chart containing all Feast components and dependencies. Most users will use this chart, but can selectively enable/disable subcharts using the values.yaml file.

* [Feature Server](charts/feature-server): High performant JVM-based implementation of feature server.

* [Transformation Service](charts/transformation-service): Transformation server for calculating on-demand features

* Redis: (Optional) One of possible options for an online store used by Feature Server
