title: Delete large data with same partition key from DynamoDB
body: <p>I have DynamoDB table structured like this</p>
  
  <pre><code>A   B    C    D
  1   id1  foo hi
  1   id2  var hello
  </code></pre>
  
  <p><code>A</code> is the partition key and <code>B</code> is the sort key.</p>
  
  <p>Let' say I only have the partition key and don't know the sort key and I'd like to delete all entries have the same partition key.</p>
  
  <p>So I am thinking about loading entries by query with a fixed size (e.g 1000) and delete them in a batch until there are no more entries with the partition key left in DynamoDB.</p>
  
  <p>Is it possible to delete entries without loading them first?</p>
