title: How to sort DynamoDB table by a single column?
body: <p>I'd like to list records from my DDB table ordered by creation date.
  My table has an attribute <code>DateCreated</code>.</p>
  <p>All examples I can find describe ordering within some partition.
  But I want global ordering.
  Am I supposed to create an artificial attribute which will have the same value across all records, just to use it as a partition key? E.g. add new attribute <code>GlobalPartition</code> with value <code>1</code> to every record in the table, and create a GSI with partition key <code>GlobalPartition</code> and sort key <code>DateCreated</code>. Isn't there a better way?</p>
  <p>Thx!</p>
