推荐答案

为什么你需要一个术语呢？如果要在网上找到一些东西，最好告诉我们你在寻找什么。



我从来没有听说过这样的术语，但这是拉动的一部分技术，与推技术形成对比。

这意味着拉动是一件坏事，这是定期轮询，因为网络通信模式的严苛限制。服务器端没有推送新添加的修改到客户端。这是一个松散的情况：如果您更频繁地进行轮询，则会浪费资源和流量，如果您很少轮询，则会在两者之间丢失事件。



这是客户端 - 服务器数据库技术和Web的问题;并且存在一些解决方案（服务器推送）。太糟糕了，您没有提供有关您正在使用的技术的任何信息。有关详细信息，请参阅我之前的回答：

Why would you need a term for that? If this is to find something on the Web, better tell us what you are looking for.

I never heard about such term, but this is a part of "pull technology", in contrast to "push technology".
That means that "pulling" is a bad thing, this is periodic polling because of the draconian limitation of the model of the network communication. The server side is not "pushing" newly added modification to the client. This is a loose-loose situation: if you poll more frequently, you waste resources and traffic for nothing, if you poll rarely, you loose events in between.

This is a problem with the client-server database technologies and the Web; and some work-around solutions exist ("server push"). Too bad, you did not provide any information on the technologies you are using. For further detail, please see my past answer:
Application 'dashboard' for website accounts[^].
