title: DynamoDB: Query all data and sorted by date descending
body: <p>I'm new to the AWS DynamoDB and need a guidance from the experts in here. </p>
  
  <p>I'm creating an application that will display a list of events with a condition the event date must be greater than today date and order by event date descending. My table schema like below:</p>
  
  <p>Partition key = eventid</p>
  
  <p>Sort Key = eventdate</p>
  
  <p>If I use relational db i can use "SELECT * FROM events where eventdate > todaydate ORDERBY eventdate DESC", but how i want to achieve this with AWS DynamoDB? I'm looking to use QUERY instead of SCAN.</p>
