Implement event-driven architectures with Amazon DynamoDB

This article discusses implementing near real-time Time-to-Live (TTL) for Amazon DynamoDB using Amazon EventBridge Scheduler, addressing limitations in DynamoDB's native TTL functionality.

• Native DynamoDB TTL can take up to a few days to delete expired items
• The solution uses EventBridge Scheduler to delete items within 1-2 minutes of expiration
• Key components include DynamoDB, DynamoDB Streams, AWS Lambda, and EventBridge Scheduler
• A Lambda function processes stream events and creates/updates/deletes EventBridge schedules
• Benefits include near real-time data accuracy, improved user experience, and optimized resource utilization

The solution provides a more precise and immediate approach to managing time-sensitive data in DynamoDB, with minimal additional cost and complexity.
