使用 CloudWatch Events 自動化 DataBrew

Amazon CloudWatch Events 可讓您自動化您的AWS服務，並自動回應系統事件，例如應用程式可用性問題或資源變更。來自AWS服務的事件會以近乎即時的方式交付至 CloudWatch Events。您可編寫簡單的規則，來指示您在意的事件，以及當事件符合規則時所要自動執行的動作。可以自動觸發的動作如下：

  • 叫用 Amazon EC2 執行命令

  • 將事件轉傳至 Amazon Kinesis Data Streams

  • 啟用AWS Step Functions狀態機器

  • 通知 Amazon SNS 主題或 Amazon SQS 佇列

DataBrew 會在您AWS帳戶中的資源狀態變更時，向 CloudWatch Events 報告事件。盡可能發出事件。

以下是數個事件的範例，顯示 DataBrew 任務的各種狀態：SUCCEEDED、TIMEOUT、 FAILED和 STOPPED。
