title: Cassandra 1.1: querying multiple row keys, but not a range
body: <p>I have read a lot of documentation about building reverse indexes in Cassandra, but I've seen nothing about how to then use these results to fetch the applicable rows.</p>
  
  <p>I know about row slices, but that doesn't apply here. My question is: how does one fetch a large number of specific rows according to the row key?</p>
  
  <p>In pseudo-SQL:</p>
  
  <pre><code>SELECT * FROM table where Primark_Key IN (2, 32, 76, 1000, 2427)
  </code></pre>
