SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the complexity of implementing caching by providing a structured framework to classify data staleness, select appropriate cache layers, and enforce correct invalidation patterns to prevent stale data issues.

Core Features & Use Cases

  • Data Inventory Analysis: Systematically categorizes data types by access patterns and staleness tolerance.
  • Strategy Selection: Maps data requirements to optimal cache layers like CDN, KV store, or in-memory.
  • Anti-Pattern Auditing: Identifies dangerous practices such as cache-as-truth or broad invalidation that lead to system instability.
  • Use Case: Use this when designing a new API architecture to ensure that real-time inventory data is never cached while static assets are aggressively cached at the edge.

Quick Start

Use the design-cache-strategy skill to audit the current data access patterns and propose an invalidation strategy for the user session and product catalog services.

FAQPage Schema
How do I determine the optimal caching layers for different data access patterns?▼

Determining optimal caching layers requires evaluating data access patterns to map staleness tolerance to appropriate storage like CDN, KV store, or in-memory. Systematically categorizing data types ensures static assets hit edge caches while real-time data remains uncached.

What is the best way to prevent stale data issues during system architecture reviews?▼

Preventing stale data issues requires enforcing canonical database source-of-truth principles and precise cache invalidation logic. Auditing for dangerous anti-patterns like cache-as-truth or broad invalidation ensures system stability and data consistency.

How do I set appropriate TTL settings and invalidation strategies for an API architecture?▼

Setting appropriate TTL settings and invalidation strategies involves classifying data staleness tolerance and mapping requirements to optimal cache layers. This structured framework prevents stale data by ensuring correct invalidation patterns are applied to specific data types.

Can I use this approach to debug data consistency issues in existing services?▼

You can debug data consistency issues by auditing current data access patterns for dangerous anti-patterns. Identifying cache-as-truth practices or broad invalidation helps isolate the root cause of staleness and instability in user session or product catalog services.

When should I not use aggressive caching at the edge?▼

Aggressive edge caching should not be used for real-time inventory data or information with low staleness tolerance. Apply edge caching only to static assets while maintaining direct database access for data requiring strict consistency.
