Seems to not work with a redis cluster.

Please see the issue I opened here: redis/ioredis#431

Has someone tested it on their own and can confirm that it's broken/not broken?

Just to have all the information complete, here are the relevant docker-compose services:

    redis-primary:
        image: bitnami/redis:latest
        environment:
            - REDIS_REPLICATION_MODE=master
        volumes:
            - ./_redisdata:/bitnami/redis
        restart: always

    redis-secondary:
        image: bitnami/redis:latest
        depends_on:
            - redis-primary
        environment:
            - REDIS_REPLICATION_MODE=slave
            - REDIS_MASTER_HOST=redis-primary
            - REDIS_MASTER_PORT=6379
        restart: always

And here is the DS config:

plugins:
  message:
    name: redis
    options:
      nodes:
       - host: "redis-primary"
         port: 6379
       - host: "redis-secondary"
         port: 6379
      maxRedirections: 16
      scaleReads: slave
      redisOptions:
        foo: bar # just to have an entry here, otherwise the connector will fail in another way
  cache:
    name: redis
    options:
      nodes:
       - host: "redis-primary"
         port: 6379
       - host: "redis-secondary"
         port: 6379
      maxRedirections: 16
      scaleReads: slave
      redisOptions:
        foo: bar

I created a little demo project to show the failure. https://github.com/PhillippOhlandt/deepstream-redis-cluster
