Stream Amazon DynamoDB table data to Amazon S3 Tables for analytics

This article discusses how to stream data from Amazon DynamoDB to Amazon S3 Tables for advanced analytics, offering two primary implementation patterns for change data capture and real-time data replication.

• Pattern 1 uses DynamoDB Streams with Lambda and Amazon Data Firehose for near real-time data replication
• Pattern 2 uses Kinesis Data Streams for extended data retention and multiple stream consumers
• S3 Tables provide native Iceberg support with benefits like ACID transactions, schema evolution, and optimized query performance
• The solution uses AWS CDK to deploy a serverless data pipeline with comprehensive error handling
• Analytics can be performed using Amazon Athena, with sample queries demonstrating transaction and risk analysis

The architecture enables organizations to maintain a transactional database while simultaneously performing complex analytics without impacting performance, using a fully managed solution with minimal operational overhead.
