Hi @joeylee2023! I'm Dosu and I’m helping the dify team.

Dify supports both single-node Redis and Redis Cluster mode, but these are separate deployment modes. A single-node Redis instance cannot operate as a Redis Cluster; Redis Cluster mode requires multiple nodes and specific configuration. If you want to use Redis Cluster mode with Dify, you need to set REDIS_USE_CLUSTERS=true and provide your cluster node addresses in the REDIS_CLUSTERS environment variable. The system will then initialize a RedisCluster client and connect to your cluster as expected. For details, see the configuration examples in the .env.example file and the Redis client initialization logic.

To reply, just mention @dosu.
