WP Engine is limiting long queries (longer than 1024 characters) for performance reasons. The above line in wp-config.php prevents that.
A performance tip: if you are hosting your website on WP Engine, and your site is using the Pods plugin, experiment with the Pods Alternative Cache add-on plugin. It was developed for and tested specifically on the WP Engine platform to improve the performance of cached objects generated from Pods (but it works on other hosting providers too). See our Pods page for more info.
