For users with very latency-sensitive and high QPS use-cases, Feast offers a high-performance Java feature server.

Besides the benefits of running on JVM, this implementation also provides a gRPC API, which guarantees good connection utilization and

small request / response body size (compared to JSON).

You will need the Feast Java SDK to retrieve features from this service. This SDK wraps all the gRPC logic for you and provides more convenient APIs.

This chart will deploy two services: `feature-server` and `transformation-service`.
268-
Both must have read access to the registry file on cloud storage. Both will keep a copy of the registry in their memory and periodically refresh it, so expect some delays in update propagation in exchange for better performance.

The next step would be to install an L7 Load Balancer (eg, [Envoy](https://www.envoyproxy.io/)) in front of the Java feature server.
273-
For seamless integration with Kubernetes (including services created by Feast Helm chart) we recommend using [Istio](https://istio.io/) as Envoy's orchestrator.

This chart will deploy a single service.

It will keep a copy of the registry in their memory and periodically refresh it, so expect some delays in update propagation in exchange for better performance.

In order for the Go feature server to be enabled, you should set `go_feature_serving: True` in the `feature_store.yaml`.

Autogenerated from chart metadata using [helm-docs v1.11.0](https://github.com/norwoodj/helm-docs/releases/v1.11.0)
40+
41+
42+
Docker repository and tag are required. Helm install example:
43+
```
44+
helm install feast-feature-server . --set image.repository=REPO --set image.tag=TAG
45+
```
46+
47+
Deployment assumes that `feature_store.yaml` exists on docker image. Example docker image:
48+
```
49+
FROM python:3.8
50+
51+
RUN apt update && \
52+
apt install -y jq
53+
54+
RUN pip install pip --upgrade
55+
56+
RUN pip install feast
57+
58+
COPY feature_store.yaml /feature_store.yaml
59+
```
60+
61+
Furthermore, if you wish to use the Go feature server, then you must install the Apache Arrow C++ libraries, and your `feature_store.yaml` should include `go_feature_server: True`.
62+
For more details, see the [docs](https://docs.feast.dev/reference/feature-servers/go-feature-server).
63+
The docker image might look like:
64+
```
65+
FROM python:3.8
66+
67+
RUN apt update && \
68+
apt install -y jq
69+
70+
RUN pip install pip --upgrade
71+
72+
RUN pip install feast
73+
74+
RUN apt update
75+
RUN apt install -y -V ca-certificates lsb-release wget
76+
RUN wget https://apache.jfrog.io/artifactory/arrow/$(lsb_release --id --short | tr 'A-Z' 'a-z')/apache-arrow-apt-source-latest-$(lsb_release --codename --short).deb
77+
RUN apt install -y -V ./apache-arrow-apt-source-latest-$(lsb_release --codename --short).deb
78+
RUN apt update
79+
RUN apt -y install libarrow-dev
80+
