hi @joelchen unfortunately i am not familiar enough with Codis right now. Is Codis able to work with my own defined Redis server instances instead of Redis server instances started by Codis ?

@centminmod I'm not familiar with Codis either. I'm researching the available options for Redis Cluster for my project, and came across your benchmark and Codis.
