Redis Caching Patterns
Overview
Use this skill to design cache behavior that improves performance without silently violating correctness expectations.
Scope Boundaries
- Use this skill when the task matches the trigger condition described in
description. - Do not use this skill when the primary task falls outside this skill's domain.
Shared References
- Cache invalidation rules:
- references/cache-invalidation-rules.md
Templates And Assets
- Redis cache policy template:
- assets/redis-cache-policy-template.md
- Cache observability checklist:
- assets/cache-observability-checklist.md
Inputs To Gather
- Read/write hotspots and latency objectives.
- Freshness and consistency constraints.
- Redis memory/eviction limits.
- Failure/degradation expectations.
Deliverables
- Key namespace and TTL/invalidation policy.
- Stampede/hot-key mitigation plan.
- Cache observability and operational guardrails.
Workflow
- Define cache policy in
assets/redis-cache-policy-template.md. - Apply freshness/invalidation rules from
references/cache-invalidation-rules.md. - Validate stampede and hot-key behavior.
- Define failure behavior for cache misses/outages.
- Finalize with
assets/cache-observability-checklist.md.
Quality Standard
- Key strategy is consistent and ownership is explicit.
- Invalidation policy matches correctness requirements.
- Failure paths preserve system correctness.
- Observability supports rapid cache regression diagnosis.
Failure Conditions
- Stop when invalidation policy cannot satisfy correctness bounds.
- Stop when cache behavior is unobservable in production.
- Escalate when caching introduces tail-latency or error regressions.
