I am interested to learn more about connection pooling in rails. Is there any good articles about this? I want to know specifically how is connection pooling in rails works. Does rails open one connection to the database for every user that is connected or does every user share the same database connection? Does different app server handles connection pooling differently [i.e passenger, unicorn, mongrel, thin] ? Or does app server doesn’t really care about this?
Thank you very much in advance for your help and insights.
