Write the online store configuration
provider says which system holds the values, key says how a row is addressed and ttl says how long a value may be served before it is considered stale.
echo 'online_store:\n provider: redis\n connection_string: "redis://localhost:6379"\n key: "feast:user_activity"\n ttl: 86400' > ~/feast/online_store.yaml - 2 locked · each failed submit reveals one
