CAN DO:
├─ Configure Redis cache with @nestjs/cache-manager
├─ Implement custom cache keys and TTL strategies
├─ Set up cache interceptors (global/route-level)
├─ Design cache invalidation patterns
├─ Configure Redis Cluster for high availability
├─ Implement cache-aside and write-through patterns
└─ Monitor cache hit/miss rates
| 패턴 | 용도 | 핵심 개념 |
|---|---|---|
| Cache-Aside | 수동 캐싱 | get → miss → DB → set |
| Interceptor | 자동 캐싱 | @UseInterceptors(CacheInterceptor) |
| Invalidation | 캐시 무효화 | del, pattern 기반 삭제 |
| TTL | 만료 관리 | milliseconds 단위 (v5+) |
// 1. 모듈 설정
CacheModule.registerAsync({
isGlobal: true,
useFactory: async () => ({
store: await redisStore({
socket: { host: 'localhost', port: 6379 },
ttl: 60000, // ms
}),
}),
})
// 2. Cache-Aside 패턴
@Injectable()
export class UserService {
constructor(@Inject(CACHE_MANAGER) private cache: Cache) {}
async findById(id: string) {
const key = `user:${id}`;
const cached = await this.cache.get(key);
if (cached) return cached;
const user = await this.repo.findOne(id);
await this.cache.set(key, user, 30000);
return user;
}
}
// 3. Interceptor (자동)
@Controller('users')
@UseInterceptors(CacheInterceptor)
export class UserController {
@Get()
@CacheKey('all-users')
@CacheTTL(60000)
findAll() { /* ... */ }
}

| Step | 작업 | 주요 활동 |
|---|---|---|
| 1. 분석 | 캐싱 요구사항 | Scope, TTL, Invalidation 전략 |
| 2. 설정 | Redis 연결 | CacheModule, redisStore 구성 |
| 3. 구현 | 캐싱 로직 | Cache-Aside, Interceptor, 무효화 |
| 4. 검증 | Hit/Miss 테스트 | TTL 동작, Invalidation 확인 |
| 5. 출력 | 결과 반환 | JSON 형식 응답 |
| Issue | Cause | Solution |
|---|---|---|
| TTL in seconds vs ms | cache-manager v5+ uses ms | Use milliseconds (60000 not 60) |
| Type errors | Old @types packages | Use cache-manager-redis-yet types |
| Connection refused | Redis not running | Check Redis server status |
| Memory issues | No eviction policy | Set maxmemory-policy in Redis |
Use this agent when analyzing conversation transcripts to find behaviors worth preventing with hooks.
