AWS CDK 2.47.0でDynamoDBの作成: 備忘録

準備

npm i -g aws-cdk
npm i @aws-cdk/aws-dynamodb

実行

mkdir fanzamodb
cd fanzamodb
cdk init sample-app --language=typescript

lib/fanzamodb-stack.tsを編集

import * as dynamodb from "aws-cdk-lib/aws-dynamodb";
import { Duration, Stack, StackProps, RemovalPolicy } from "aws-cdk-lib";
import { Construct } from "constructs";
import * as lambda from "@aws-cdk/aws-lambda";

export class FanzamodbStack extends Stack {
  constructor(scope: Construct, id: string, props?: StackProps) {
    super(scope, id, props);
    const table = new dynamodb.Table(this, "Table", {
      partitionKey: { name: "id", type: dynamodb.AttributeType.STRING },
      billingMode: dynamodb.BillingMode.PROVISIONED,
      readCapacity: 20,
      writeCapacity: 20,
      removalPolicy: RemovalPolicy.DESTROY,
      sortKey: { name: "createdAt", type: dynamodb.AttributeType.NUMBER },
      pointInTimeRecovery: true,
      tableClass: dynamodb.TableClass.STANDARD_INFREQUENT_ACCESS,
    });

    table.addLocalSecondaryIndex({
      indexName: "statusIndex",
      sortKey: { name: "status", type: dynamodb.AttributeType.STRING },
      projectionType: dynamodb.ProjectionType.ALL,
    });

    const readScaling = table.autoScaleReadCapacity({
      minCapacity: 1,
      maxCapacity: 50,
    });

    readScaling.scaleOnUtilization({
      targetUtilizationPercent: 50,
    });

    const globalTable = new dynamodb.Table(this, "Table", {
      partitionKey: { name: "id", type: dynamodb.AttributeType.STRING },
      replicationRegions: ["us-east-1", "us-east-2", "us-west-1"],
      billingMode: dynamodb.BillingMode.PROVISIONED,
      replicationTimeout: Duration.hours(3),
    });
    globalTable
      .autoScaleWriteCapacity({
        minCapacity: 1,
        maxCapacity: 10,
      })
      .scaleOnUtilization({ targetUtilizationPercent: 75 });
  }
}

cdk deploy

確認

AWSコンソール->DynamoDB->リージョン ["us-east-1", "us-east-2", "us-west-1"]それぞれにテーブルが作成されていることを確認
