**Usado por:** SAAS-010-webhooks, SAAS-007-notifications
|
|
|
|
## Resumen
|
|
|
|
Redis como backend para BullMQ (colas de procesamiento).
|
|
|
|
## Uso
|
|
|
|
- Cola de webhooks outbound
|
|
- Cola de notificaciones asincronas
|
|
- Cache de sesiones (opcional)
|
|
|
|
## Caracteristicas
|
|
|
|
- BullMQ para job processing
|
|
- Retry logic automatico
|
|
- Dead letter queue para fallos
|
|
- Dashboard Bull Board (opcional)
|
|
|
|
## Configuracion
|
|
|
|
```env
|
|
REDIS_HOST=localhost
|
|
REDIS_PORT=6379
|
|
REDIS_PASSWORD=... # opcional
|
|
REDIS_DB=0
|
|
```
|
|
|
|

## Manejo de Errores
|
|
| Codigo | Descripcion | Accion |
|
|
|--------|-------------|--------|
|
|
| ECONNREFUSED | Conexion rechazada | Verificar servicio Redis |
|
|
| ETIMEDOUT | Timeout | Retry con backoff |
|
|
| NOAUTH | Sin autenticacion | Configurar REDIS_PASSWORD |
|
|
| OOM | Sin memoria | Escalar o limpiar cache |
|
|
|
|
## Fallbacks
|
|
|
|
### Estrategia Redis Fallback
|
|
|
|
| Escenario | Estrategia |
|
|
|-----------|------------|
|
|
| Redis no disponible | Memory cache temporal (node-cache) |
|
|
| Conexion perdida | Reconexion automatica con backoff |
|
|
| Cluster failover | Redis Sentinel para HA |
|
|
| Memoria llena | Eviction LRU automatico |
|
|
|
|
### Configuracion Sentinel (Alta Disponibilidad)
|
|
|
|
```typescript
|
|
// Configuracion recomendada para produccion
|
|
{
|
|
sentinels: [
|
|
{ host: 'sentinel-1', port: 26379 },
|
|
{ host: 'sentinel-2', port: 26379 },
|
|
{ host: 'sentinel-3', port: 26379 }
|
|
],
|
|
name: 'mymaster',
|
|
sentinelRetryStrategy: (times) => Math.min(times * 100, 3000)
|
|
}
|
|
```
|
|
|
|
### Circuit Breaker
|
|
|
|
- Umbral apertura: 5 fallos consecutivos
|
|
- Timeout semi-abierto: 30 segundos
|
|
- Fallback: In-memory cache con TTL reducido
|
|
|
|
## Multi-tenant
|
|
- Credenciales: Global (una instancia Redis compartida)
|
|
- Configuracion: Por tenant via prefijos de clave
|
|
- Aislamiento: Prefijo tenant_id en todas las operaciones (keys: tenant:{tenant_id}:*)
|
|
|
|
## Testing
|
|
### Sandbox/Test Mode
|
|
- Usar Redis local o redis-mock para tests
|
|
- DB separada para tests (REDIS_DB=1)
|
|
- Fixtures disponibles para testing unitario
|
|
|
|
## Monitoreo
|
|
| Metrica | Descripcion | Alerta |
|
|

|
|
| Latencia | Tiempo de respuesta | >2s |
|
|
| Errores | Tasa de errores | >1% |
|
|
| Disponibilidad | Uptime del servicio | <99.9% |
|
