Question : How to guarantee HA of redis-cluster-proxy #84

I've tried this app out and find that it is very nice! My question is: Considering that Redis itself has replica mode to guarantee HA, is there any measure to guarantee HA of redis-cluster-proxy? If yes, then how to use redis-cluster-proxy in replica mode? If no, then do you have any plan about this?

AFAIK, proxy needn't have replica mode. This repo proxy also doesn't support. For HA, maybe you can use DNS/VIP that contain many proxies ip, you parse DNS/VIP to get all proxy instances, and connect one of them. Connect another proxy instance if one is failed. Moreover, you also add into new proxy instances into DNS/VIP to guarantee there always are some available proxy instances.

We use "keepalived" to provide a virtual IP with 3 servers.
