title: Cassandra timeuuid comparison
body: <p>I have a table, </p>
  
  <pre><code>CREATE TABLE log (
      uuid uuid,
      time timeuuid,
      user text,
      ....
      PRIMARY KEY (uuid, time, user)
  )  
  </code></pre>
  
  <p>and</p>
  
  <blockquote>
    <p>CREATE CUSTOM INDEX time_idx on Log(time) USING 'org.apache.cassandra.index.sasi.SASIIndex';</p>
  </blockquote>
  
  <p>then I want to select base on time</p>
  
  <blockquote>
    <p>select * from Log where time >  84bfd880-b001-11e6-918c-24eda6ab1677;</p>
  </blockquote>
  
  <p>and nothing return, it will return if I use equal(=). Which step did I go wrong ?</p>
