Description (last modified by Vsevolod Timchenko)

The RedisCacheClient is explicitly initialized with the standard Redis client from the redis-py library:

        import redis

        self._lib = redis
        ...
        self._client = self._lib.Redis

To work with clusterized deployments another class, RedisCluster, has to be used. It offers support for cluster features and peculiarities, i.e. smart retries and refreshes on MOVED errors as well as node discovery.

Relevant piece of code:

Redis class that I propose to support:
