title: What happends to a failed message in AWS SQS if there is no redrive policy set?
body: <p>I do understand that when I want my failed messages to be moved to a DLQ I can use a redrive policy, where I can mention the number of retries and the DLQ name.</p>
  
  <p>What happens if I don't set a redrive policy? What is the default retry number and what happens when the number of retries exceeds the threshold?</p>
  
  <p>Your responses are highly appreciated.</p>
