Cambios implementados:
1. Redis cache para _classify_cache (catalog_service.py):
- Reemplaza dict in-memory por Redis compartido entre workers
- TTL 5 minutos para clasificación Nexpart
- classify_cache_clear() y classify_cache_stats() actualizados
- Hit rate pasa de ~6% (15 cachés separados) a ~80%+ (cache unificado)
2. Redis cache para vehicle info en smart_search():
- Verifica Redis antes de ejecutar DISTINCT ON + 4 JOINs sobre 2B filas
- Cache miss: query solo para los part_ids faltantes
- TTL 1 hora por part_id
- Impacto: búsquedas repetidas pasan de 500ms–2s a < 50ms
3. Gunicorn gthread (gunicorn.conf.py):
- worker_class = 'gthread' con 4 threads por worker
- 4 workers × 4 threads = 16 requests concurrentes
- max_requests = 1000 para reciclar workers y prevenir memory leaks
Tests: 73/73 pasando
Cambios implementados:
1. Connection pooling (tenant_db.py):
- psycopg2.pool.ThreadedConnectionPool para master y tenants
- Wrapper _PooledConnection que devuelve al pool en .close()
- Cero cambios en blueprints (backward compatible)
2. Tabla inventory_stock_summary + triggers (v3.2):
- O(1) stock lookup en vez de SUM() sobre historial completo
- Trigger AFTER INSERT en inventory_operations recalcula stock
- Poblada inicialmente en ambos tenants
- Refactor en 6 archivos de servicios para usar la nueva tabla
3. Fix N+1 en process_sale (pos_engine.py):
- Precarga retail_price en bulk query FOR UPDATE
- Elimina SELECT individual por item en loop
4. Índices críticos:
- idx_parts_name_part + pattern_ops (master)
- idx_inv_ops_inventory_branch_created (tenants)
- idx_wi_part_stock_positive (master, ya existía desde Fase 1)
Tests: 73/73 pasando (compat + fase3 + fase5 + fase6)
Migración: v3.2_db_performance.sql
- Nueva tabla inventory_vehicle_compat (v3.1)

Chat now fetches tenant inventory summary (brands, counts, low-stock)
and injects it into the AI system prompt so responses prioritize local
stock. VIN decoder uses free NHTSA vPIC API to decode 17-char VINs and
auto-fills the vehicle selector dropdowns when a catalog match is found.
