isRedisCluster config

[tonystaark]

If I am using AWS to configure the redis cluster, do I need to specify isRedisCluster : true, in my redis config in local app?
In the AWS, I have already configured my clusters there.
Because if I specify the isRedisCluster in the app, and I do not specify the nodes options, my backend calling that involves redis operations will hang indefinitely.
So my question is whether I can choose not to specify isRedisCluster and the nodes options at all, and solely depends on my aws config, or do I need to specify them in the local app and pass my value from AWS config into koa redis?
