title: What options are there to speed up a full repair in Cassandra?
body: <p>I have a Cassandra datacenter which I'd like to run a full repair on. The datacenter is used for analytics/batch processing and I'm willing to sacrifice latencies to speed up a full repair (<code>nodetool repair</code>). Writes to the datacenter is moderate.</p>
  
  <p>What are my options to make the full repair faster? Some ideas:</p>
  
  <ul>
  <li>Increase <code>streamthroughput</code>?</li>
  <li>I guess I could disable autocompation and decrase <code>compactionthroughput</code> temporarily. Not sure I'd want to that, though...</li>
  </ul>
  
  <p>Additional information:</p>
  
  <ul>
  <li>I'm running SSDs but haven't spent any time adjusting <code>cassandra.yaml</code> for this.</li>
  </ul>
