使用create-function 命令建立一個 Lambda 函數。 aws lambda create-function --function-name ProcessDynamoDBRecords \ --zip-file fileb://function.zip --handler example.handler --runtime nodejs18.x \ --role arn:aws:iam::
首先我们通过sam init 命令初始化一个包含AWS Lambda、API Gateway、DynamoDB资源的应用模版。 输入sam init ,选择"AWS Quick Start Templates" 询问选择的模版,选择"Serverless API" 询问选择的runtime,这里选择nodejs16.x 询问是否使用X-Ray追踪应用性能,选择y 输入project name 完成后我们将有一个quick start的模...
相对DynamoDB表的schema-free模式,TcaplusDB采用的是schema架构,即需要用户提前定义好表的schema,但与传...

Lambda 既然是个方法,就要选择相应的 Runtime 环境,如下图所示,总有一款适合你的(最近在用 Node.js, 这里就用这个吧) 点击右下角的 Create function 按钮进入配置页面 在上图红色框线的位置就可以配置出发 Lambda 的触发器了,点击 Add trigger 从上图可以看出,AWS 内置的很多服务都可以触发 Lambda,我在工作中...
从上图可以看出,AWS 内置的很多服务都可以触发 Lambda,我在工作中常用的有: APIGateway (一会的 demo 会用到,也是最常见的调用方式) ALB - Application Loac Balancer CloudFront DynamoDB S3 SNS - Simple Notification Service SQS - Simple Queue Service ...
import{DynamoDBProvider}from'@aws-lambda-powertools/parameters/dynamodb';constdynamoDBProvider=newDynamoDBProvider({tableName:'my-table'});exportconsthandler=async():Promise<void>=>{// Retrieve a value from DynamoDBconstvalue=awaitdynamoDBProvider.get('my-parameter');console.log(value);}; ...
(3) Using an Amazon DynamoDB table to filter duplicate events If you need the output object to have the same bucket name and key but you cannot set user-defined metadata, use this design: Inthis example, there are two Lambda functions and a DynamoDB table. The first function writes the...
