 ## Reusing Persistent Connections
 If you're using AWS Lambda, be sure to set `context.callbackWaitsForEmptyEventLoop = false;` in your main handler. This will allow the freezing of connections and will prevent Lambda from hanging on open connections. See [here](https://www.jeremydaly.com/reuse-database-connections-aws-lambda/) for more information.
