  1. 顶一下。
     
  2. If you are looking at CEP, the current market leaders are:
    1) Apama (hugely expensive)
    2) Aleri

    Other runner-up are:
    3) Corel8
    4) StreamBase

    Good blog: http://apama.typepad.com/

    It will be interesting to see how CEP is develop in China for the next few years
     
  3. A new addition with release of Microsoft SQL 2008 StreamInsight
     
  4. 偶又來挖墳啦~~剛注意老外的菜譜里時不時提到這個,查了一下,果然海洋上的先人已經曬過啦~

    Esper在双2GHz CPU的Intel系统测试环境下,处理超过500 000个事件/秒;在VWAP基准测试中在有1000语句的情况下,引擎延时平均小于3微妙(在10us时超过99%的预测准确率)——最高时有70 Mbit/s流量并占用85%的CPU资源。

    虽然这个基准测试是基于一个相当简单的用例,其发表的目的是震动整个行业,因为它提供了完整的工具集来重现测试结果。Esper事件服务器监听远端客户端通过网络传送过来的股票市场事件信息。Esper引擎是通过一个滑动的时间窗口或事件窗口,来实时计算输入信息的成交量加权平均价。
