Hot-path cache

Redis Cache Architecture

Wrong caching means dirty reads at best and stampedes at worst. Clarify the boundary before choosing the build path.

Cache tiers, key design, TTL and stampede protection.

Measure then change Slow logs and load tests before index/schema changes.
Rollback-minded changes Schema changes ship with scripts and rollback thinking.
Capacity planning Estimate growth before sharding—avoid early complexity.

Cache issues

These usually show up before a project starts—or right after a rushed launch.

01

No TTL—teams then argue across ownership lines.

02

Key collisions—it often surfaces only after production impact.

03

Unordered dual writes—iteration and local integration slow down.

04

Large keys—users feel it as inconsistent data or UX.

Invalidatable read models

Cache rebuildable data; TTL+active invalidate; single-flight hot keys; monitor hit rate and memory. Define what is cacheable, TTLs and consistency expectations. Design keyspace and protections—Redis isn't a second unreliable DB.
