title: Random Data From Cassandra DB
body: <p>I'm using the Random Partitioner, and I'm wondering if there's a way to do the equivalent of a range scan to get a batch of random rows.  I assume that the rows are rather randomly placed on disk across the cluster?</p>
  
  <p>In other words, given a row key in a random partition, is there a way to get X number of neighbors to that row as a random sample of data?</p>
