Hi,

I am writing a web application that uses compojure and monger 2.0.0-rc1.

I have learnt that I should only be connecting to mongodb once and not on every request.

So I need to be able to share this connection across different requests. Is there any recommendation on how I could check if a connection is already established ?

Thanks,

Aneesh

You probably want to store your connection somewhere, since in 2.0 connection is a required argument.

I recommend using Component but you can also store a connection in a var and check if it's bound with clojure.core/bound?.
