title: How do you define a relay connection for pagination against an ORM?
body: <p>I've looked through all of Relay's documentation and there doesn't seem to be a straightforward explanation on how to build a Relay connection with an ORM. All the examples seem to use the <code>connectionFromArray</code> method which is fine if you're storing your data in memory but when you're storing the data in a database how would you go about providing the information necessary for a connection's pagination to work?</p>
