title: Cassandra TimeOut?
body: <p>I have a large dataset in a single table (over 2 million rows, each with over 100 columns), stored in cassandra, a few months ago  (2 maybe?) I was able to execute a simple command to keep track of the amount of records in that table: </p>
  
  <pre><code>SELECT count(*) from mydata limit 11111111;
  </code></pre>
  
  <p>A few days ago I tried the same command and got the following error:</p>
  
  <pre><code>errors={}, last_host=168.176.61.25
  </code></pre>
  
  <p>The error itself does not say much, After some research on google I think it might be related to a timeout. As you might expect shorter running queries execute properly, and the error appears always after some 10 seconds of processing.</p>
  
  <p>A far as I understand, the timeouts for cassandra are set in cassandra.yaml, I have changed the following values</p>
  
  <p>read_request_timeout_in_ms: 25000 </p>
  
  <p>range_request_timeout_in_ms: 25000</p>
  
  <p>request_timeout_in_ms: 25000</p>
  
  <p>However there is no change at all on the error and it still fails after the same 10 seconds,</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks a lot</p>
