In general I think you're right but I'm not sure why you would have 5,000 connections to each node. There isn't any reason I can think of to maintain more than 1 connection per client (application process) to each node. You don't gain anything by 'connection pooling' with Redis so it's not like each app server would want to keep a 100 connection pool around. I guess you could have an issue if you have 5000 application processes all wanting to connect to a single redis cluster, but I'd argue that you'd be well past the point of needing to break your system into services by then anyway.
