# cache-setup

Set up caching: Redis, Memcached, or in-memory caching for API responses, sessions, and expensive computations. Use when the goal asks to add caching, improve response times, or reduce database load.

## Goal pattern

cache redis memcached caching performance speed up response time

## Parameters

- backend (choice [default: auto]): Cache backend

## Steps

1. [analyst] Identify cache targets: expensive queries, API responses, session data, and computed results. Choose the cache backend.

2. [analyst] Set up the cache client: install Redis/Memcached driver, configure connection, add health checks. (after: step-0)

3. [analyst] Implement caching patterns: cache-aside, write-through, or write-behind. Define TTLs and invalidation strategies. (after: step-1)

4. [analyst] Add cache warming: pre-populate hot keys on startup. Add cache stampede protection (locks/lease). (after: step-2)

5. [analyst] Monitor and tune: add hit/miss metrics, measure latency improvement, and tune TTLs based on access patterns. (after: step-3)
