高频更新到UI网格. [英] High frequency updates to a UI grid.

问题描述

大家好.

我有一个托管一个网格的屏幕，该网格显示了我从多个来源接收到的数据，并且每秒最多可以进行1000次更新.读取有关多个对象的X coordiante位置的信息.我通过创建一个缓存来维护更改并将网格绑定到数据集来开始设计.在数据不那么繁重之前，我使用了另一个数据集作为缓存(具有相同的架构)，并在UI上使用了计时器，我从cache_DS进行getchanges，与UI_DS合并，并接受更改.由于数量急剧增加，因此我开始考虑使用其他机制，基本上是一个哈希表(用于高查找)，并且在发生任何更改时，都会在哈希表上更新数据.我在UI上创建了一个计时器，每增加1.5秒就会滴答一次，我会从哈希表中获取所有更新.我的问题是:如何确定使用该设计已更新了哪些节点?哈希表具有键和值，键是对象名称，值是x coordiante.

I have a screen hosting one grid, that grid shows data I recieve from multiple sources and can reach up to 1000 updates per second.  Reading information on X coordiante positions of a number of objects. I started the design by creating a cache to maintain the changes , and binding the grid to a dataset. Before the data was not that heavy so I uised another dataset as a cache ( with the same schema), and with a timer on the UI, I go and getchanges, from the cache_DS, merge with the UI_DS, and accept changes. Since the volume has increased dramatically I started thinking of a different mechanis, basically a hashtable ( for high lookups ) , and when any change occurs, the data is updated on the hashtable. I created a timer on the UI that ticks every 1.5 seconds upen which I go to get any updates from the hashtable. my question is : How do I figure out which nodes have been updated using this design? the hashtable has keys and values, keys being the object name, and value being the x coordiante.

推荐答案

所以您有一个数据集/缓存的数据表-如何将记录放在那里?您可以从缓存"表中选择"记录的主要思想是第一个表中不存在.您必须放置一些键"，然后从中进行选择.

So you have a dataset/datatable for cache - how do you put records there ? The main idea that you can 'SELECT' records from 'cache' table that not exist in first table. You have to put some 'keys' and then SELECT from them.

 

这是我的2美分
