** Leveraging EventBridge Pipes and Firehose for Real-time DynamoDB Data Querying via Athena

Amazon's DynamoDB, a highly scalable NoSQL database, has limited query capabilities. To overcome this limitation, users can export DynamoDB data to S3 in near real-time using EventBridge Pipes and Firehose, allowing them to query it with SQL via Amazon Athena.

This approach enables the combination of DynamoDB's scalability with the flexibility of SQL queries, offering a truly serverless approach to SQL querying. The solution is built using CDK and TypeScript, covering both single- and multiple-table designs.

While this method has advantages, such as efficient data storage and optimized query performance, it also introduces complexities, including potential delay in real-time data storage and the need for custom queries to account for deleted or updated records.

Amazon Athena's cost-effectiveness is a significant benefit; however, handling duplicate records or complex queries may lead to performance trade-offs, especially with large datasets.
