有没有更好的方法来为繁忙的交通网页创建实时排行榜？

Question

我使用从php中的mysql数据库获取的数据在web应用程序中创建了一个排行榜。网页还有其他功能以及其他sql查询。排行榜的参考是

what is the best practice leaderboard with php, mysql, memcached?，

  

让我担心的问题是有更好的方法来考虑   制作排行榜应用程序？

与此同时，我遇到了Firebase，并且能够在Fiddle中运行代码，如下所示：

 var LEADERBOARD_SIZE = 6;

  var scoreListRef = new Firebase('https://i62qrqslypp.firebaseio-demo.com//scoreList');

  var htmlForPath = {};

  function handleScoreAdded(scoreSnapshot, prevScoreName) {
    var newScoreRow = $("<tr/>");
    newScoreRow.append($("<td/>").append($("<em/>").text(scoreSnapshot.val().name)));
    newScoreRow.append($("<td/>").text(scoreSnapshot.val().score));


    htmlForPath[scoreSnapshot.key()] = newScoreRow;

    // Insert the new score in the appropriate place in the table.
    if (prevScoreName === null) {
      $("#leaderboardTable").append(newScoreRow);
    }
    else {
      var lowerScoreRow = htmlForPath[prevScoreName];
      lowerScoreRow.before(newScoreRow);
    }
  }

  function handleScoreRemoved(scoreSnapshot) {
    var removedScoreRow = htmlForPath[scoreSnapshot.key()];
    removedScoreRow.remove();
    delete htmlForPath[scoreSnapshot.key()];
  }

  var scoreListView = scoreListRef.limitToLast(LEADERBOARD_SIZE);


  scoreListView.on('child_added', function (newScoreSnapshot, prevScoreName) {
    handleScoreAdded(newScoreSnapshot, prevScoreName);
  });

  scoreListView.on('child_removed', function (oldScoreSnapshot) {
    handleScoreRemoved(oldScoreSnapshot);
  });


  var changedCallback = function (scoreSnapshot, prevScoreName) {
    handleScoreRemoved(scoreSnapshot);
    handleScoreAdded(scoreSnapshot, prevScoreName);
  };
  scoreListView.on('child_moved', changedCallback);
  scoreListView.on('child_changed', changedCallback);


  $("#scoreInput").keypress(function (e) {
    if (e.keyCode == 13) {
      var newScore = Number($("#scoreInput").val());
      var name = $("#nameInput").val();
      $("#scoreInput").val("");

      if (name.length === 0)
        return;

      var userScoreRef = scoreListRef.child(name);

      userScoreRef.setWithPriority({ name:name, score:newScore }, newScore);
    }
  });
