title: DynamoDB createTable if not exists
body: <p>Hi need to create a table on DynamoDB. The problem is, if it exists <code>createTable</code> response is an error. How do i avoid that. Because I throw a notification when error occurs, but in this case, I don't want to.</p>
  
  <p>I don't want to compare the error code because <code>ResourceInUseException</code> is too vague for it. Also, I don't think sending a describe table request first is really a proper solution.</p>
  
  <p>Is there any way to <code>createIfNotExists</code>?</p>
