Implement event-driven architectures with Amazon DynamoDB – Part 3

This article is Part 3 of a series demonstrating how to implement event-driven architectures using Amazon DynamoDB, focusing on scheduling future actions based on data writes to a DynamoDB table.

• Uses DynamoDB Streams and AWS Lambda to automatically schedule future actions
• Enables precise event scheduling using Amazon EventBridge Scheduler
• Demonstrates a workflow for creating time-based schedules from DynamoDB item writes
• Provides an example of scheduling email reminders for appointments or subscriptions
• Includes sample Node.js Lambda function code to process stream events and create schedules

The solution allows for reliable, scalable event-driven workflows by leveraging DynamoDB Streams, Lambda, and EventBridge Scheduler to trigger downstream actions at specific times based on stored data.
