Ok after reading this over a few times I've realized that you wrote broken code on purpose to prove the switching was working.
Did you turn on the middleware that will automatically swap based on HTTP verb? If you didn't your POST/GET requests won't switch connections automatically. If you're in a model/controller/test you need to wrap it in a `connected_to` block like this ``` ActiveRecord::Base.connected_to(role: :reading) do # read from your replica end ``` Rails can't know if your replica is up to date so we didn't implement always select from the replica, you have to tell it you want that.
