 QueryService queryService = PoolManager.find("client").getQueryService();
 CqAttributesFactory cqAf = new CqAttributesFactory();
 CqAttributes cqa = cqAf.create();
 
 String cqQueryStr = "SELECT * FROM /root/employees " +
   "WHERE salary > 50000";
   
 CqQuery cq = queryService.newCq("MyCq", cqQueryStr, cqa); 
 CqResults results = cq.executeWithInitialResults();     
 
 for (Object o : results.asList()) {
   Struct s = (Struct)o;
   System.out.println("key : " + s.get("key") + " value : " + s.get("value"));
