## Próximos Pasos (Roadmap restante)
|
||
|
||
### Opción C — Consolidación Técnica (en progreso)
|
||
1. **Materialized view `part_vehicle_preview`** — Fallback robusto al Redis cache para vehicle info
|
||
2. **Fix cache warming script** — Autonomía sin `sudo -u postgres`
|
||
3. **CSS dinámico residual** — Extraer CSS inyectado por JS a archivos externos
|
||
4. **Load testing script** — Benchmark básico de endpoints críticos
|
||
5. **Docs audit** — Corregir métricas y marcar estado post-FASE 7
|
||
|
||
### Opción A — Arquitectura (pendiente)
|
||
1. **Serialización `orjson`** — 2-10× faster JSON
|
||
2. **Virtual scroll** — Tablas grandes sin lag
|
||
3. **Celery worker queue** — Tareas pesadas async
|
||
4. **Asyncpg + Quart PoC** — Evaluar I/O no bloqueante para catálogo
|
||
5. **Particionar `vehicle_parts`** — Escalabilidad ilimitada (254 GB → particiones)
|
||
|
||
### Features de Negocio (futuro)
|
||
1. **Mercado Libre / Amazon sync** — Publicar inventario en marketplaces
|
||
2. **IA por voz (Chalán de Nexus)** — Web Speech API → chatbot existente
|
||
3. **PWA mejorada** — Offline mode, install prompt, background sync
|
||
4. **Portal de proveedores** — Demand analytics, heatmaps, stock recommendations
|
||
5. **Dashboard in-app** — Gráficos de rendimiento en tiempo real
