# Feast Java components (deprecated) [](https://github.com/feast-dev/feast-java/actions/workflows/complete.yml) ### Note: This repository worked with Feast 0.9 and before. Please look at http://github.com/feast-dev/feast for the more up to date version of this repo. ### Overview This repository contains the following Feast components. * Feast Core: The central feature registry used to define and manage entities and features. * Feast Serving: A service used to serve the latest feature values to models. * Feast Java SDK: A client used to retrieve features from Feast Serving. * Helm Charts: The repository also contains Helm charts to deploy Feast Core and Feast Serving into a Kubernetes cluster. ### Architecture  * Feast Core has a dependency on Postgres. * Feast Serving has a dependency on an online store (Redis) for retrieving features. The process of ingesting data into the online store (Redis) is decoupled from the process of reading from it. Please see [Feast Spark](https://github.com/feast-dev/feast-spark) for more details about ingesting data into the online store. * Feast Serving has a dependency on Feast Core. * The Go and Python Clients are not a part of this repository. ### Contributing Guides on Contributing: - [Contribution Process for Feast](https://docs.feast.dev/v/master/contributing/contributing) - [Development Guide for Feast](https://docs.feast.dev/contributing/development-guide) - [Development Guide for feast-java (this repository)](./CONTRIBUTING.md) ### Installing using Helm Please see the Helm charts in [charts](infra/charts).
