Query All Google App Engine

Im trying to build a query that get all rows in datastore,but my problem is that i have hundreds of rows and when i try to run one time,i almost get limits quotas.. So my question is,what im doing wrong? 

Query query = new Query(myObject);
 PreparedQuery pq = datastore.prepare(query);
 QueryResultList<Entity> results = pq.asQueryResultList(fetchOptions);
 resp.setContentType("text/plain");
 resp.getWriter().println(results.size());
 for (Entity entity : results) {
  resp.getWriter().println("entity.getProperty("name")");

What you have wrong is your algorithm. You cant do that with many rows since your frontend will timeout. Look at task queues and backends.
