Redis

Description
The Redis online store provides support for materializing feature values into Redis.
Both Redis and Redis Cluster are supported.
The data model used to store feature values in Redis is described in more detail here.
Getting started
In order to use this online store, you'll need to install the redis extra (along with the dependency needed for the offline store of choice). E.g.
pip install 'feast[gcp, redis]'
pip install 'feast[snowflake, redis]'
pip install 'feast[aws, redis]'
pip install 'feast[azure, redis]'
You can get started by using any of the other templates (e.g. feast init -t gcp or feast init -t snowflake or feast init -t aws), and then swapping in Redis as the online store as seen below in the examples.
Examples
Connecting to a single Redis instance:
feature_store.yaml
project: my_feature_repo
registry: data/registry.db
provider: local
online_store:
  type: redis
  connection_string: "localhost:6379"
Connecting to a Redis Cluster with SSL enabled and password authentication:
feature_store.yaml
project: my_feature_repo
registry: data/registry.db
provider: local
online_store:
  type: redis
  redis_type: redis_cluster
  connection_string: "redis1:6379,redis2:6379,ssl=true,password=my_password"
The full set of configuration options is available in RedisOnlineStoreConfig.
