批量计算服务(BatchCompute)使用 MNS 提供的主题模式来实现消息通知。

用户负责主题(Topic)的创建、管理和订阅,并在使用 BatchCompute 创建集群或提交作业时指定主题相关的配置。BatchCompute 依据配置向指定用户主题推送消息。用户可在 MNS 控制台配置 URL、队列、邮件和短信四种方式获取消息通知。目前,BatchCompute 主要支持两大类消息事件,即集群事件和作业事件。

A) 开通消息服务

B) 创建 MNS 主题

C) 创建 MNS 主题订阅

1. 授权 BatchCompute 推送消息

请登录控制台上进行一键授权。如果没有授权过,控制台会出现这个提示:授权如果已经授权,过请忽略。

2. 计费相关

消息通知产生的费用统一由 消息服务结算 ,批量计算不再额外收取。

3. 消息类型

A) 集群事件

使用 SDK 或控制台创建集群(cluster)时,可以配置如下类型消息事件。

{
    "Notification": {
        "Topic": {
            "Name": "test-topic",
            "Endpoint": "http://[UserId].mns.[Region].aliyuncs.com/", 
            "Events": [
                "OnClusterDeleted",
                "OnInstanceCreated",
                "OnInstanceActive"
            ]
        }
    }
}
字段 说明
Name MNS 主题名称
Endpoint MNS 私网 Endpoint,参考 如何获取 Endpoint

B) 作业事件

使用 SDK 或控制台创建作业(job)时,可以配置如下类型消息事件。

{
    "Notification": {
        "Topic": {
            "Name": "test-topic",
            "Endpoint": "http://[UserId].mns.[Region].aliyuncs.com/",
            "Events": [
                "OnJobWaiting",
                "OnJobRunning",
                "OnJobStopped",
                "OnJobFinished",
                "OnJobFailed",
                "OnTaskWaiting",
                "OnTaskRunning",
                "OnTaskStopped",
                "OnTaskFinished",
                "OnTaskFailed",
                "OnInstanceWaiting",
                "OnInstanceRunning",
                "OnInstanceStopped",
                "OnInstanceFinished",
                "OnInstanceFailed",
                "OnPriorityChange"
            ]
        }
    }
}
字段 说明
Name MNS主题名称
Endpoint MNS私网Endpoint,参考 如何获取Endpoint。
