AWS CDK中 aws-kinesis 模块的 CfnDeliveryStream 类可以配置Kinesis Delivery Stream的动态分区。需要在 ExtendedS3DestinationConfiguration 属性中设置 S3Configuration 对象的 dynamicPartitioningConfiguration 属性为 DynamicPartitioningConfiguration 对象。示例代码如下：

import * as cdk from 'aws-cdk-lib';
import * as kinesis from 'aws-cdk-lib/aws-kinesis';
import * as s3 from 'aws-cdk-lib/aws-s3';
import { Construct } from 'constructs';

class MyStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const deliveryStream = new kinesis.CfnDeliveryStream(this, 'MyDeliveryStream', {
      deliveryStreamName: 'my-delivery-stream',
      deliveryStreamType: 'DirectPut',
      extendedS3DestinationConfiguration: {
        bucketArn: 'arn:aws:s3:::my-bucket',
        roleArn: 'arn:aws:iam::1234567890:role/my-delivery-stream',
        dynamicPartitioningConfiguration: {
          enabled: true,
          retryOptions: {
            durationInSeconds: 300
          }
        }
      }
    });

    const bucket = new s3.Bucket(this, 'MyBucket', {
      bucketName: 'my-bucket',
    });

    bucket.grantReadWrite(deliveryStream);
  }
}
