我正在尝试使用 esper 时间间隔 (timer:interval) 为 perseo CEP 建模规则，就像http://esper.espertech.com/release-6.1.0/esper-reference/html/event_patterns 上记录的那样。 html#pattern-atoms。

特别是这个必须每 20 秒触发一次的示例永远不会执行：

{
    "name": "timer_interval_update",
    "text": "select *,\"timer_interval_update\" as ruleName from pattern [every timer:interval(20 sec)]",
    "action": {
        "type": "update",
        "parameters": {
            "id":"${id}",
            "type":"A",
            "attributes": [
                {
                    "name": "status",
                    "value": "open",
                    "type": "text"
                }

            ]
        }
    }
}

在我收到的 perseo-core 日志中：

我正在使用使用此 docker-compose 的 dockerized 环境：
