title: Boto3: Is there a way to batch get items using hash range keys from dynamodb?
body: <p>I see from their documentation you can batch_get_item for single items</p>

  <p>but I'm not quite sure how to get items from tables with hash range keys. Particularly batch getting items with just the hash value, is this possible?</p>
