Wso2 匹配没有事件的情况

我有一个简单的对象状态流：

define stream statusStream (id string, success bool);

我想查询自5分钟以来“失败”（success=false）的所有对象：statusStream（，false）的所有事件，其中5分钟内没有事件（相同id，true）

对于这种工作，最简单的siddhi查询是什么

目前我有：

define stream statusStream (id string, success bool);

from statusStream[ success == false ]#window.time(5 minutes)
insert expired events into expiredStatusStream;

from every status = statusStream[ success == false ]
  -> ackStatus = statusStream[ success == true and id == status.id]
    or expiredStatus = expiredStatusStream[ id == status.id ]
select status.id, ackStatus.id as ackId
into filteredStatusStream;

from filteredStatusStream[ ackStatus.id is null ]
insert into failedStatusStream;

---

如果您收到“success==false”消息表示失败，请尝试以下执行计划：

@Import('statusStream:1.0.0')
define stream statusStream (id string, success bool);

@Export('alertStream:1.0.0')
define stream alertStream (alert string);

from statusStream
select id, success, time:timestampInMilliseconds() as ts
insert into statusStreamWithTS;

from every e1=statusStreamWithTS[success==false], statusStreamWithTS[success==false]*, e2=statusStreamWithTS[success==false AND (e2.ts - e1.ts) >= 500000]
select 'some message' as alert
insert into alertStream;

在这里，如果我们在5分钟内继续收到“success==false”消息，将生成一个警报
