# Schéma Base de Données Veza

> Référence complète du schéma PostgreSQL — 60+ tables, UUIDs, soft deletes.
> Source : `veza-backend-api/internal/models/` (68 fichiers Go) et `migrations/` (115 fichiers SQL)
> ORM : GORM v1 (mapping uniquement, migrations 100% SQL)

## Stratégie de migration

- **Migrations SQL pures** dans `veza-backend-api/migrations/` (001 à 115+)
- **GORM** utilisé uniquement pour le mapping Go ↔ PostgreSQL, pas pour la création de schéma
- **AutoMigrate()** est vide — tout est géré par SQL
- **Outil** : `go run ./cmd/migrate_tool/main.go up` (ou `down` pour rollback)
- Table `schema_migrations` pour le suivi des migrations appliquées

## Conventions

- **Clés primaires** : UUID v4 (`uuid.UUID` avec `google/uuid`)
- **Soft delete** : Colonne `deleted_at` indexée sur 20+ tables
- **Timestamps** : `created_at`, `updated_at` sur toutes les tables
- **JSONB** : Utilisé pour les données flexibles (social_links, specs, metadata)
- **Enums** : Types PostgreSQL custom (user_role, track_status, etc.)
- **Foreign keys** : Contraintes PostgreSQL natives, toujours actives

## Utilisation de Redis

Redis est **optionnel** — dégradation gracieuse si indisponible.

| Cas d'usage | Pattern de clé | TTL | Fallback |
|-------------|---------------|-----|----------|
| **Sessions** | `sessions:{token_hash}` | Configurable | Table `sessions` |
| **Cache HTTP** | `http_cache:{sha256(url)}` | 5-15 min | Pas de cache |
| **Rate limiting** | `ratelimit:{key}` | Variable | In-memory avec mutex |
| **Verrouillage compte** | `lockout:{email}:count`, `lockout:{email}:locked_until` | Configurable | In-memory map |
| **Token blacklist** | `token_blacklist:{jti}` | Durée JWT | Pas de révocation |
| **Présence utilisateur** | `presence:{user_id}` | Variable | Table `user_presence` |
| **Cache applicatif** | Via `CacheService` | Variable | Pas de cache |

Headers de cache : `X-Cache: HIT` ou `X-Cache: MISS`
