Implement Redis-based caching for improved performance

[mn3m-24]

Summary

Implement Redis as a caching layer in the CartCraze application to improve performance and reduce load on the primary data store.

Motivation

• Improve response times by reducing database queries
• Enable scalability as user activity increases
• Decrease latency for frequently accessed data (such as product, cart, and session information)

Proposed Approach

• Integrate Redis server with the application
• Identify key data/services for caching (e.g., product catalog, cart contents, session data)
• Implement cache storage and retrieval logic
• Establish cache invalidation/expiration strategies
• Add necessary environment and configuration variables
• Document caching behavior and configuration

Acceptance Criteria

• Redis is successfully integrated into the codebase
• Frequently read data is cached and retrieved from Redis
• Cache behavior is tested, and performance improvements are demonstrated
• Documentation is updated with configuration and operational details

Additional Notes

• Ensure that sensitive data is not cached in Redis
• Follow best practices for Redis connection security and resource management
