# Enterprise Upgrade - Phase 1 Progress

## ✅ Completed

### Infrastructure
- [x] **Docker Compose:** Added PostgreSQL (pgvector) and Redis services with resource limits
- [x] **PM2 Config:** Created `ecosystem.config.js` for background process management
- [x] **Logger:** Implemented Winston logger with file rotation (`apps/backend/src/utils/logger.ts`)
- [x] **Redis Event Bus:** Created `RedisEventBus.ts` to replace in-memory EventEmitter

### Dependencies Installed
- [x] `winston` (Logging)
- [x] `ioredis` (Redis client)
- [x] `pm2` (Process manager - global)

## 🚧 Next Steps

### 1. Prisma Setup
- [x] Install Prisma: `npm install --save-dev prisma @prisma/client`
- [x] Create comprehensive schema in `prisma/schema.prisma`
- [x] Update `.env.example` with PostgreSQL and Redis URLs
- [ ] Initialize database: `npx prisma migrate dev --name init`
- [ ] Run migration script: `node dist/scripts/migrate-to-postgres.js`

### 2. Integrate RedisEventBus
- [ ] Update `apps/backend/src/mcp/EventBus.ts` to use Redis in production
- [ ] Test event persistence across server restarts

### 3. Database Adapters
- [x] Create `PrismaDatabaseAdapter.ts`
- [x] Create `PgVectorStoreAdapter.ts` (replaces ChromaDB)
- [ ] Update `UnifiedMemorySystem` to use Prisma adapter
- [ ] Update all code references from ChromaDB to PgVector


## 🎯 How to Start Services

```bash
# 1. Start Docker services in background
docker-compose up -d

# 2. Build backend
cd apps/backend && npm run build

# 3. Start backend with PM2
pm2 start ecosystem.config.js

# 4. Check status
pm2 status
docker ps
```

## 📊 Resource Usage Target
- **Postgres:** Max 512MB RAM, 0.5 CPU
- **Redis:** Max 256MB RAM, 0.25 CPU
- **Backend (PM2):** Max 1GB RAM (autorestart)

**Status:** Foundation laid. Ready for Prisma integration.
