title: aws lambda function triggering multiple times for a single event
body: <p>I am using aws lambda function to convert uploaded wav file in a bucket to mp3 format and later move file to another bucket. It is working correctly. But there's a problem with triggering. When i upload small wav files,lambda function is called once. But when i upload a large sized wav file, this function is triggered multiple times.</p>
  
  <p>I have googled this issue and found that it is stateless, so it will be called multiple times(not sure this trigger is for multiple upload or a same upload).</p>

  <p><strong>Is there any method to call this function once for a single upload?</strong></p>
