title: Dynamodb scan in sorted order
body: <p>Hi I have a dynamodb table. I want the service to return me all the items in this table and the order is by sorting on one attribute.</p>
  
  <p>Do I need to create a global secondary index for this? If that is the case, what should be the hash key, what is the range key? 
  (Note that query on gsi must specify a "EQ" comparator on the hash key of GSI.)</p>
  
  <p>Thanks a lot!</p>
