Recently I have asked the same question over here. Here is the mail thread. I have gone through a post and I have done my integration and it works well with my staging server. I would like to know is there would be any performance issue or does this integration may create an issue within app? Has anyone does this kind of integration?
(Note: I can’t upgrade my app as I am using Mongoid as my ORM and Mongoid doesn’t support Rails5 as of now)
