选择lambda-dynamodb-stream 表。 在Exports and streams(导出和流)下,选择 DynamoDB stream details(DynamoDB 流详细信息)。 选择打开。 对于视图类型,选择仅键属性。 选择开启流。 记下流 ARN。在下一步中将该流与 Lambda 函数关联时,您将需要此类信息。有关启用流的更多信息,请参阅使用DynamoDB Streams 捕获...
OLD_IMAGE— 整个项目在修改前的显示。 NEW_AND_OLD_IMAGES— 项目的新旧映像。 您可以随时启用或禁用流。但是,如果您尝试在已有流的表上启用流,则会收到 ValidationException。如果您尝试在没有流的表上禁用流,也会收到 ValidationException。 当您将 StreamEnabled 设置为 true 时,DynamoDB 将创建一个新流,并...

利用Lambda与DynamoDB Streams构建动态仪表板:第一部分原文链接:
To use zero-ETL integration, you will first need to enablepoint-in-time recovery (PITR)on your table. Once PITR is enabled, select the ‘new and old images’ option for your DynamoDB streams. The integration operates without impacting DynamoDB table throughput, providing a safe ...
NEW_AND_OLD_IMAGES—Both the new and the old images of the item You can process DynamoDB streams in multiple ways. The most common approaches useAWS Lambdaor a standalone application that uses theKinesis Client Library (KCL)with the DynamoDB Streams Kinesis Adapter. The KCL is a client-sid...

AWS Lambda based incremental backup The DynamoDB Stream StreamViewType needs to be one of NEW_IMAGE, NEW_AND_OLD_IMAGES, or KEYS_ONLY. Note that DynamoDB Streams does not support encryption at rest. const Backup = require('dynamodb-backup-restore').Backup; module.exports.handler = (event,...
