Implement Advanced DynamoDB Features in Social Media Application

Amazon DynamoDB provides a structured, scalable, and fully managed NoSQL database solution designed for high-performance applications.

This Cloud Lab offers a hands-on experience with several key DynamoDB features. You‘ll begin by creating two tables, one for storing user posts and another for user profiles. To enhance query efficiency, you will configure both local and global secondary indexes. Next, you’ll enable DynamoDB Streams on the user posts table to monitor and react to changes in posts. Finally, you’ll demonstrate how to achieve idempotency using DynamoDB’s transaction APIs to ensure safe and repeatable write operations.

By the end of this Cloud Lab, you’ll be confident in implementing these advanced features in your own DynamoDB tables. The lab environment’s provisioned architecture is shown below.
