[CDK] Enable Kinesis DS from DDB stream

You can do this in CDK by few lines of code:

import * as cr from "@aws-cdk/custom-resources";

    const ddbToKinesis = new cr.AwsCustomResource(
  this,
  "CustomResourceDDBtoKinesis",
  {
    policy: cr.AwsCustomResourcePolicy.fromStatements([
      new iam.PolicyStatement({
        actions: [
          "dynamodb:EnableKinesisStreamingDestination",
          "dynamodb:DisableKinesisStreamingDestination",
          "dynamodb:DescribeKinesisStreamingDestination",
        ],
        effect: iam.Effect.ALLOW,
        resources: [tableArn],
      }),
      new iam.PolicyStatement({
        actions: ["kinesis:*"],
        effect: iam.Effect.ALLOW,
        resources: [streamArn],
      }),
    ]),
    onCreate: {
      service: "DynamoDB",
      action: "enableKinesisStreamingDestination",
      parameters: {
        StreamArn: streamArn,
        TableName: tableName,
      },
      physicalResourceId: cr.PhysicalResourceId.of(Date.now().toString()),
    },
    onDelete: {
      service: "DynamoDB",
      action: "disableKinesisStreamingDestination",
      parameters: {
        StreamArn: replicationStream.streamArn,
        TableName: tableName,
      },
      physicalResourceId: cr.PhysicalResourceId.of(Date.now().toString()),
    },
    installLatestAwsSdk: true,
  }
);
