title: Dynamodb - Get all rows with a hash key
body: <p>Is there a way to get all rows from DynamoDB that use a specific hash key when your rows use both hash key and range key?</p>
  
  <p>Example:
  <code>
  Hash           Range 
  A              B
  A              C
  A              D
  E              F
  </code></p>
  
  <p>Then getItems(Hash=A) returns 3 rows</p>
