Separate read-only instance from read/write instance #180

Closed rcurrington closed 3 years ago

I don't see anything in the default config for separating out a read only connection. I'm using AWS Elasticache and have a cluster setup for caching. AWS is able to provide endpoints for read/write and read only. As of right now, all read and writes are happening on the same instance. Is there any additional configuration that can be added to support this functionality?

Use your configuration endpoint. https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Endpoints.html#Endpoints.Find.RedisCluster

Thanks for the tip! Is there a max version of the redis engine that this plugin supports?

I'm running Redis 6 just fine. Redis is really good at being backwards compatible. I just upgraded a server from Redis 1.x to Redis 6 without any code changes.

Thank you

BTW, you are probably way overprovisioned if you're using a cluster. A single node will run thousands of cmd/sec just fine.
