我一直在研究Drools Fusion复杂事件处理组件和WSO2 复杂事件处理器/ Siddhi ,我想知道这些组件中的一个/两个是否能够处理2D 和 3D 事件的空间事件。

我有兴趣创建触发器,例如:

  • 如果 2 点之间的距离小于 [X] 英里
  • 如果对象在区域/多边形内
  • 如果对象在区域/多边形之外

是否可以创建这些触发器,或者我是否需要编写扩展/自定义函数?

如果空间事件是可能的,我在哪里可以找到一些我可以查看的文档。

到目前为止我发现了什么:

流口水融合: http ://blog.athico.com/2009/10/secret-sauce.html | 表明基于空间的问题应该是可能的(但是这是一个旧的来源)。

空间和时间推理的规则引擎?| 类似的问题,但它很老

(对不起 [Link]: 部分,我似乎不能发布超过 2 个链接,因为我是新来的。)

感谢您的时间和精力!

此致,

I won't be able to answer regarding support in Drools Fusion since am not much aware of Drools. Regarding WSO2 CEP, you can find some articles in [1,2]. More functionalities are being added to Siddhi as extensions by using external libraries as discussed in the architecture@wso2.org mail thread pointed out by you in the question.

Also there is some work for a geo dashboard done in [3]. There are no publicly available articles/ tutorials as yet on these, but you can drop a mail to dev@wso2.org to get more info on the implementation details, capabilities, if you are interested.. :-)
