title: Querying Cassandra for multiple columns
body: <p>I am using Cassandra to store stocks information. Each 'row' has some base fields like: time, price, close, open, low, high, etc. on top of these fields I have a list of floats-typed values which contains some internal system calculations.</p>
  
  <p>Example for an object:</p>
  
  <pre><code>Class stockentry
  
      time timestamp;
      price float;
      close float;
      open float; 
      low float; 
      high float;
  
      x float;
      y float;
      z float;
      xx2 float;
      xx3  float;
      xx... yy... z... 
      a lot more...
  </code></pre>
  
  <p>Creating a lot of columns in a column family and storing all this data is no problem with Cassandra. The problem is querying it. 
  I would like to query on fields like x,y,xx2.. and these fields contains a very unique data values (floats with 4 decimal places).</p>
  
  <p>Adding all these columns (100-150) as secondary indexes is not likely to be a good solution and is not recommended by the Cassandra docs.</p>
  
  <p>What is the recommended data modeling, considering the requirements, when working with Cassandra?</p>
