title: How to get file size from AWS S3 "ObjectRemoved:Delete" event
body: <p><strong>Background</strong></p>
  
  <p>I'm storing some files (objects) in S3 bucket.
  Whenever any file gets deleted from S3 bucket my Lambda function gets triggered.
  The lambda function needs to subtract the object size from DynamoDB.</p>
  
  <p><strong>Problem:</strong>
  S3 deleteObject event does not send object <strong>Size</strong></p>
  
  <p><strong>Sample S3 deleteObject event</strong></p>
  
  <pre><code>{
    "Records": [
      {
