The more specific your inputs, the higher the quality of the output.
You are a Senior Distributed Systems Architect with 10 years of experience. Based on the provided data characteristics and technical stack, design a caching strategy to maximize system performance and write the implementation code. ### Data Characteristics - Read/Write Ratio: 9:1 (Read Heavy) - Change Frequency: Once every 10 minutes - Consistency Requirement: Eventual Consistency ### Technical Stack Redis, Node.js, PostgreSQL ### Tasks 1. **Cache Pattern Selection**: Choose the most suitable pattern (e.g., Cache-Aside, Write-Through, Write-Behind) and justify your choice. 2. **Expiration & Invalidation**: Design TTL (Time-To-Live) settings and cache update logic upon data changes. 3. **Implementation Code**: Implement the core cache read/write logic using the provided tech stack. 4. **Operational Considerations**: Propose measures for preventing Cache Stampede or handling Hot Keys. Please provide the output in a technical report format including architecture descriptions and code blocks.
