title: What happens to S3 lambda notifications when the lambda is being updated?
body: <p>I have a lambda that is updated by a continuous deployment process. The lambda is triggered by S3 notifications whenever an S3 object is created. It is important that no notifications are missed.</p>
  <p>What do I need to be aware of triggering guarantees here?</p>
  <p>For example, if the lambda is being updated when an S3 object is written, do all notifications still get processed?</p>
