title: How reduce cassandra virtual memory usage?
body: <p>Is there a settings in cassandra to reduce it memory usage? I understand that cassandra manages memory well, but for testing purposes I do not want to spent 6Gb memory only when cassandra service running on my windows mchine.</p>
  
  <p><strong>UPDATED</strong></p>
  
  <p>I have tired setting <code>disk_access_mode: standart</code> instead of <code>disk_access_mode: auto</code>. It was not help. Also I pay attention that in cassandra 2.0.9 <code>cassandra.yaml</code> file do not contains <code>disk_access_mode</code> by  default. So it seems (but I not sure) that <code>disk_access_mode</code> was removed from cassandra.</p>
