+Lazy Collections
+================
+
+To create a lazy collection you can extend the
+``Doctrine\Common\Collections\AbstractLazyCollection`` class
+and define the ``doInitialize`` method. Here is an example where
+we lazily query the database for a collection of user records:
+
+.. code-block:: php
+    use Doctrine\DBAL\Connection;
+
+    class UsersLazyCollection extends AbstractLazyCollection
+    {
+        /** @var Connection */
+        private $connection;
+
+        public function __construct(Connection $connection)
+        {
+            $this->connection = $connection;
+        }
+
+        protected function doInitialize() : void
+        {
+            $this->collection = $this->connection->fetchAll('SELECT * FROM users');
+        }
+    }
