title: tinkerpop driver - janusgraph lose data - new vertex is not stored
body: <p>I try to add data to an existing janusdb on cassandra storage.</p>
  
  <p>I use tinkerpop driver.</p>
  
  <p>In this way i create a traversal:</p>
  
  <pre><code>g = traversal().withRemote(DriverRemoteConnection.using(host,port,"g"));
  </code></pre>
  
  <p>And in this way I add user</p>
  
  <pre><code>g.addV("User").properties("name",name).hasNext();
  </code></pre>
  
  <p>Then i try to recover user from DB</p>
  
  <pre><code>g.V().has("name",user).values("name")   
  </code></pre>
  
  <p>But user not found  </p>
  
  <p>Same result from gremlin console</p>
  
  <pre><code>graph.addVertex(label, 'User', 'name', 'ciro2')
  </code></pre>
  
  <p>If i search user in same session i find it. If I close session and restart console I can't found user.</p>
  
  <p>Ok after using commit command, the data persist in database, but only from console.</p>
  
  <pre><code>graph.tx().commit();
  </code></pre>
