  • 基于分发机制的公众订阅平台设计


    • 分发的throughput。由于群发的放大效应,如何让拥有大量订阅用户的企业帐号能及时投递消息。以及到客户端的移动push通道也存在throughput的问题。
    • 存储的性能,根据客户端的访问型态,如果考虑数据保存在云端,大多需要更新最近联系人、用户与企业订阅帐号之间的会话索引,以及每个会话的未读提醒数。由于客户端本地也可以保存部分数据,因此不同的实现型态可能云端存储及更新的数据有一定差异。
    • 分发及存储模型。分发指数据投递推拉方式的选取,由于筛选条件及通过移动网络主动push的可能性,推送方式可以更好满足业务型态。存储模型指如何选择合适的模型让上万订阅用户的推送能更及时快捷。

      shell and gave it to my 4 year old daughter
      and said “You can hear the ocean if you put this to your ear.” She placed the shell to her ear and screamed.
      There was a hermit crab inside and it pinched her ear.
      She never wants to go back! LoL I know this is entirely off topic but I had to tell someone!

      The actors and the producers will disappear. So will the cricketers and the franchisee owners, in case IPL fails with the paying public.
