Issue #, if available:
Description of changes:
Overview
This PR adds serverless pattern demonstrating real-time data processing using DynamoDB Streams, AWS Lambda, and Amazon SNS for inventory monitoring and notifications.
Features
L2 Construct Implementation: Fine-grained control over DynamoDB streams with custom Lambda configuration
L3 Construct Implementation: Simplified best-practice implementation using AWS Solutions Constructs
Real-time Inventory Monitoring: Automatically detects when item count reaches zero and sends notifications
Error Handling: Implements SQS Dead Letter Queue for Lambda function failure handling
Security: Uses KMS encryption for SNS topics and SQS queues
Usage
The pattern triggers notifications when inventory items reach zero count, making it ideal for stock management and alerting systems.
